It’s critical to comprehend the essential phases of EV powertrain software development before delving into the details of the MBD approach and how Dorleco tools support development.

1. Requirement gathering and analysis:

Development teams examine the functional and performance needs of the electric vehicle powertrain system at the outset of the process. At this point, it’s important to comprehend how the various parts of the powertrain will work together as well as how the control software will operate the entire system to meet objectives like performance, safety, efficiency, and range optimization.

2. Control Design and Architecture:

Creating the control system architecture comes next after defining the requirements. This involves defining the control logic and creating algorithms that can manage the intricacies of the powertrain, such as coordinating motor control and controlling energy flows. At this point, interactions with further parts, such as the battery and transmission systems, are also specified.

3. Model-Based Design:

Model-Based Design (MBD) is used in this situation. The powertrain system’s physical components are represented mathematically by MBD, which also simulates their interactions in a controlled setting. By taking this step, it is certain that design problems can be found and fixed early on, which lowers the expense of repairing them later.

4. Testing and Validation:

Model-in-the-loop (MIL) testing is the first step in the testing process. It involves simulating and testing the control logic inside a virtual model of the system. Once confirmed, the control logic is tested in a more thorough simulation that closely resembles the actual system during the Software-in-the-Loop (SIL) phase. During the last phase, known as Hardware-in-the-Loop (HIL) testing, the control logic is implemented on hardware in real-time, and the software’s ability to communicate with physical components is tested.

5. Hardware Prototyping and Deployment:

After the simulation has been used to verify the control software, real hardware is used for testing. After verifying proper input/output responses through open-loop operation, the controller is placed through a battery of tests to verify its real-world performance.

6. Testing Hardware-in-the-Loop (HIL):

During this phase, engineers can test the controller without requiring the physical components to be present because HIL testing simulates the full plant (motor, inverter, battery system, etc.) in real time. Rapid testing under a variety of conditions is made possible by the HIL test bench, which functions as an effective virtual vehicle.

Model-Based Design (MBD) and Its Benefits

1. EV Powertrain Software Development has been transformed by Model-Based Design (MBD), which helps teams reduce the risks associated with late-stage testing and debugging. MBD provides several advantages:

This enables engineers to guarantee that the software satisfies performance requirements and optimizes control algorithms.

Through a smooth integration with test benches and labs, the VX1000 system enables developers to measure ECUs in real-time driving scenarios. Additionally, it facilitates high transfer rates for quick data processing, which boosts testing and calibration process effectiveness.

3. Highest Fidelity Ultra-HIL Testing

Thanks to its robust simulation capabilities, an extremely realistic hardware-in-the-loop (HIL) testing platform allows developers to test control software before building physical prototypes. Typhoon HIL allows for comprehensive testing under a variety of scenarios by simulating the behavior of real powertrain components (such as motors, inverters, and battery systems) in real-time.

With the help of HIL’s platform, developers can create digital twins, or virtual versions of actual powertrain systems, which let them mimic how the systems would behave in various operating scenarios. Additionally, the platform facilitates automated testing, which enables developers to run intricate test scenarios, repeat test cycles, and guarantee that every control software release satisfies reliability requirements.

4. NXP S32K3XX Microcontrollers

Dorleco uses this microcontroller in their VCUs. It covers the primary characteristics of the S32K344 White Board, which may be used to assess various applications, including T-boxes, Domain Controllers, BCM, and Gateways.

Internal Combustion Engine

Introduction

Internal combustion engine (ICEs), which power around 250 million roadway cars in the US alone, have been the foundation of industrial and transportation uses for more than a century. They are a powerful force in the automotive industry because of their durability, driveability, and compatibility with a wide range of fuels, including ethanol, natural gas, propane, diesel, gasoline, and biodiesel. Additionally, they can be included in plug-in hybrid and hybrid systems to improve range and fuel economy. Internal combustion engines are under increased scrutiny because of environmental concerns and the growing demand for greener alternatives, despite their extensive use and benefits.

Internal Combustion Engine Classification

Continuous combustion engines and intermittent combustion engines are the two main types of internal combustion engines that are distinguished by their combustion mechanisms.

1. Engines with Continuous Combustion

Fuel and oxidizer are continuously injected into these engines, maintaining a constant flame. Two of the best examples of continuous-combustion engines that are frequently used in industrial and aerospace settings are gas turbines and jet engines.

2. Engines with intermittent combustion

Conversely, the air-fuel combination is ignited in cycles by intermittent-combustion engines, commonly referred to as reciprocating engines. This group includes diesel and gasoline piston engines, which produce power by burning fuel in precise order.

The Internal Combustion Engine’s Operating Principles

The basic chemical process of combustion, in which fuel and oxygen combine to create energy, is at the heart of internal combustion engines. ICEs use direct fuel combustion to produce energy inside, as opposed to external combustion engines like steam engines.

An ICE is made up of a moving piston and a stationary cylinder. The crankshaft is turned by the piston’s movement, which is pushed by expanding combustion gases. The powertrain then uses this mechanical energy to drive the wheels of the vehicle.

Currently, there are two main categories of ICEs in production:

Spark-Ignition Gasoline Engines: These engines use a spark plug to ignite a mixture of gasoline and air before compression.

Diesel engines that use compression ignition only compress air before injecting high-pressure fuel, which ignites on its own because of the heat generated during compression.

The four-stroke cycle used by the majority of ICEs consists of four crucial stages:

The Cycle with Four Strikes

Stroke of Intake: The piston is close to the top dead center (TDC) at the start of the intake stroke. The piston descends as the intake valve opens, bringing in fuel and air (or just air in diesel engines). For the combustion chamber to receive a new charge, this stroke is necessary.

An engine cycle needs two full crankshaft revolutions (720°), and only one power stroke produces torque; the other strokes use energy.

Internal Combustion Engine Components

Important elements of an ICE consist of:

Cylinder Head: The camshaft, valves, valve buckets, return springs, spark plugs for gasoline engines, and fuel injectors for direct injection engines are all housed in the cylinder head. Additionally, it has engine coolant tubes.

Engine Block: The crankshaft, connecting rods, pistons, and cylinders make up the engine block. To regulate temperature, it also makes coolant flow easier.

Combustion Chamber: The combustion chamber is the area between the piston, cylinder head, and engine block where air-fuel combustion takes place.

Internal Combustion Engine Benefits

Compact Size: Internal combustion engines (ICEs) are substantially smaller than external combustion engines.

High Power-to-Weight Ratio: They are appropriate for transport applications due to their high power-to-weight ratio.

Portability: the ability to fit a variety of vehicles and allow for easier carrying.

Fast Start Time: Internal combustion engines (ICEs) may start nearly instantly, in contrast to steam engines.

More Efficiency: Compared to external combustion engines, it offers higher efficiency.

Reduced Maintenance: Needs comparatively less care.

Lower Lubricant Consumption: Lubrication is more effective than in external combustion engines.

Moderate Operating Temperature: In contrast to steam engines, internal combustion engines’ maximum temperatures only last a brief period.

Internal Combustion Engine Drawbacks

ICEs have significant disadvantages despite their benefits:

Limited Fuel Options: Rely on premium gaseous or liquid fuels.

High Fuel Costs: When compared to alternative energy sources, gasoline and diesel are more costly.

Environmental Issues: Compared to external combustion engines, internal combustion engines emit more pollutants.

Noise pollution: reciprocal engines produce a lot of noise during burning.

Power Restrictions: Not recommended for applications requiring a lot of power.

Internal Combustion Engine Applications

Many industries make extensive use of ICEs.

Gasoline Engines: Automobiles, boats, and airplanes all use gasoline engines.

Industries use gas engines to generate electricity.

Diesel engines power large machinery, trucks, ships, and railroads.

Industrial, maritime, and aviation settings employ gas turbines.

Internal Combustion Engines’ Future

Cleaner alternatives are becoming more and more necessary as environmental concerns and resource depletion become more urgent issues. Even with notable improvements in ICE efficiency and emissions management, their dependence on fossil fuels continues to be a major drawback.

To overcome these obstacles, research and development initiatives concentrate on:

Alternative Fuels: Sustainable substitutes include hydrogen, biofuels, and synthetic fuels.

Electrification: hybrid and plug-in hybrid technologies integrate electric motors to lower pollution and fuel consumption.

Advanced Engine Management Systems: Control systems powered by AI increase productivity.

Lightweight Materials: Better materials contribute to a lighter engine, which improves fuel economy.

Aerodynamic Enhancements: Improving a car’s aerodynamics helps it use less fuel.

Regenerative Braking Systems and Control Strategies

Introduction

Regenerative braking systems are becoming more and more common in contemporary transportation systems, such as trains, industrial equipment, and electric and hybrid cars. During braking or deceleration, this novel braking technique enables the recovery and conversion of kinetic energy into electrical energy. By doing this, regenerative braking lessens the need for traditional friction braking systems, which release kinetic energy as heat, while also greatly increasing energy efficiency.

The basic ideas of regenerative braking, its essential elements, different control schemes, and its advantages and disadvantages will all be covered in this blog. We will also emphasize how developments in this technology are pushing the limits of efficient and ecological transportation.

Regenerative Braking System Fundamentals

Energy conservation is the fundamental idea underlying regenerative braking. Conventional braking systems release heat energy into the atmosphere after converting a vehicle’s kinetic energy. Regenerative braking, on the other hand, absorbs this kinetic energy and transforms it into electrical energy. Energy waste can be minimized and efficiency increased by using the recovered energy to power the electric motor right away or storing it in batteries.

Key Components of a Regenerative Braking System

Several crucial parts make up a standard regenerative braking system:

Electric Generator/Motor: This multifunctional part transforms kinetic energy into electrical energy while braking and acts as a motor when accelerating to provide propulsion.

Energy Storage System: Depending on the use, the recovered electrical energy is kept in capacitors or batteries. The total efficiency of the vehicle can be increased by reusing this stored energy.

Control System: The control unit is in charge of controlling the energy transfer between the traction system, energy storage system, and motor/generator. It decides how much energy can be efficiently recovered and when to use regenerative braking.

Techniques for Regenerative Braking System Control

Several control mechanisms are used to optimize regenerative braking’s efficacy and efficiency. These methods maximize energy recovery while guaranteeing smooth braking performance. Below, we list some of the most popular control techniques:

Torque Blending: This tactic guarantees a seamless changeover between regenerative and friction braking. To maximize energy recovery and minimize wear on traditional brakes, the system determines the required braking force and divides it between regenerative and friction brakes.

Regeneration Prioritization: The control system prioritizes regenerative braking over friction braking when it does not completely charge the battery. The amount of battery charge and the necessary deceleration force are two examples of the variables that influence the choice between the two braking techniques.

Regenerative Braking Modes: There are various regenerative braking modes available in many electric and hybrid cars, including “high” and “low.” While the low mode simulates traditional coasting and offers a more natural driving experience, the high mode offers sharper deceleration and increased energy recovery.

Predictive Control: To maximize regenerative braking, advanced control systems use prediction algorithms based on road gradients, traffic circumstances, and driver behavior. For example, when drivers approach a stoplight, they can reduce regenerative braking, and when they approach a downhill slope, they can increase it.

Benefits of Regenerative Braking Systems

The following benefits of regenerative braking systems enhance the effectiveness, performance, and sustainability of contemporary transportation:

Increased Energy Efficiency: Regenerative braking increases overall vehicle efficiency, especially in stop-and-go traffic situations, by transforming kinetic energy into reusable electrical energy.

Increased Driving Range of Electric Vehicles (EVs): Regenerative braking in electric and hybrid cars helps increase driving range by lowering energy loss, which eventually lessens the need for frequent recharging.

Decreased Operating Costs: Regenerative braking lessens brake wear and tear by reducing the need for conventional friction brakes, which lowers maintenance and repair expenses throughout the vehicle’s life.

Improved Braking Control: Particularly in slick situations, regenerative braking systems offer more control over braking force, which lowers the chance of sliding and increases overall vehicle stability.

Environmental Benefits: Regenerative braking systems help to reduce greenhouse gas emissions and a smaller carbon footprint by minimizing energy waste and dependency on fossil fuel-based energy sources.

Predictive and Adaptive Control: Regenerative braking can adjust to different road conditions and driving styles thanks to clever control algorithms, which enhance energy recovery and overall vehicle performance.

Sustainability and Energy Recovery: Regenerative braking is an essential technology for upcoming industrial and transportation applications since it can recover and reuse energy, which is in line with global sustainability goals.

Regenerative braking systems have certain drawbacks and restrictions despite their many benefits:

High Initial Cost: Some individuals and organizations find regenerative braking technology prohibitively expensive to use due to the substantial investment needed in electric motors, control electronics, and energy storage devices.

Complexity: Regenerative braking introduces complexity to an automobile’s current systems, necessitating advanced hardware and software to efficiently control energy flow.

Weight and Space Restrictions: Adding batteries or capacitors raises a vehicle’s weight and space needs, which may affect its performance and design adaptability.

Limited Energy Recovery in Some Situations: Road conditions and driving habits affect how well regenerative braking works. Compared to stop-and-go urban driving, vehicles on highways or at consistent speeds may have less energy recovery.

Standardization and compatibility issues: When transferring between car brands or models, there may be compatibility issues because different automakers use different regenerative braking technologies.

Noise Concerns: Although this is usually a small problem, some drivers may find the sound made by regenerative braking systems strange or disturbing.

Restricted Performance at High Speeds: Regenerative braking works best at modest braking and lower speeds. During high-speed deceleration or emergency braking, it might not offer a substantial energy recovery.

Conclusion :

In terms of industrial machinery and transportation, regenerative braking systems and the control schemes that go along with them are revolutionary.

Significant advantages of these systems include increased EV range, lower maintenance costs, better braking control, decreased environmental impact, and increased energy economy.

Traction Control Systems and Chassis Control Logic

Introduction

The two most important pillars in the field of automotive engineering are performance and safety. Automakers have always tried to find a balance between these crucial elements as technology has developed.

To achieve that balance and ensure that cars provide the best possible performance while upholding the highest standards of safety and stability, contemporary developments like Traction Control Systems (TCS) and Chassis Control Logic (CCL) are essential. Modern cars now come equipped with these technologies, which increase their dependability and efficiency in a variety of driving scenarios.

The fundamentals of these technologies, their constituent parts, their interactions, and the numerous advantages they offer to the driving experience are all examined in this blog. We can understand TCS and CCL’s function in modern car dynamics by comprehending how they operate.

Traction Control Systems (TCS)

The purpose of Traction Control Systems (TCS), a crucial part of an automobile’s electronic stability control system, is to preserve the best possible wheel traction when accelerating.

The chance of losing traction in difficult driving situations rises as cars get stronger and can accelerate more quickly. TCS mitigates this risk by limiting excessive wheel spin, particularly when the car accelerates on slick terrain like snow, ice, or wet roads.

Crucial Elements and Roles of Traction Control Systems

Wheel-Speed Sensors: To track the wheels’ rotational speed, TCS installs sensors on each wheel. The system receives real-time data from these sensors and uses it to identify any variations in wheel speed, which are a sign that one or more wheels are sliding or spinning more quickly than the others.

Engine Control Module (ECM): The engine control module, or ECM, is in charge of regulating engine power to stop wheel spin. To minimize slide, the ECM can temporarily lower engine power to a tire that begins to lose traction by adjusting ignition timing or reducing throttle input.

Brake Actuation: TCS can apply brake pressure to particular wheels in addition to managing engine power. By slowing down the spinning wheel and redistributing torque, this aids in the vehicle’s traction recovery.

Intelligent Control Logic: Smart control algorithms in advanced TCS systems evaluate sensor data to identify the optimal strategy for traction maintenance without sacrificing performance. By limiting excessive wheel spin, these technologies help to maintain the best possible vehicle stability.

How TCS Works in Practice

The technology continuously tracks each wheel’s speed when the driver accelerates. The system kicks off when one or more wheels start spinning more quickly than the others, which is a sign of a loss of traction.

Either either lowering engine power or by selectively applying the brakes to one or more wheels, TCS can step in. Without requiring any input from the driver, the intervention is mild yet effective, enabling the car to restore traction swiftly and safely.

CCL, or chassis control logic

A collection of advanced technologies and control systems known as chassis control logic (CCL) maximizes a car’s handling, stability, and general driving characteristics. By combining several vehicle control technologies, this system improves performance and offers a controlled, balanced, and smooth driving experience.

The car can adjust to a variety of driving circumstances thanks to the interaction between CCL and other systems including TCS, ABS (Anti-lock Braking System), and ESC (Electronic Stability Control).

Essential Elements and Purposes of Chassis Control

Electronic Stability Control (ESC): ESC stands for Logic Electronic Stability Control. An essential component of CCL is ESC. Using the brakes selectively and, in certain situations, lowering engine power to steady the vehicle, helps avoid skidding and losing control. It works especially well when there are abrupt turns or when a car starts to oversteer or understeer.

Anti-lock Braking System (ABS): ABS keeps the wheels from locking up when applying severe braking, preserving steering control. By distributing braking forces evenly among the wheels, ABS makes it possible for the car to stop swiftly and safely without losing stability.

Electronic Brake-force Distribution (EBD): EBD modifies the brake force distribution between the front and back wheels to maximize braking. Road conditions, speed, and vehicle load are some of the variables that affect this adjustment. ABS and EBD combine to enhance total braking performance.

Adaptive Suspension Systems: Adaptive suspension systems, which automatically modify shock absorber settings, are a characteristic of certain cars with CCL. Through improved cornering stability, a smoother ride, and road condition adaptation, these systems can improve handling.

How CCL Works in Practice?

CCL collects information from a variety of sensors that track the activity of the car. These sensors, which identify any changes in the dynamics of the vehicle, include wheel-speed sensors, gyroscopes, and accelerometers.

To guarantee the best handling and stability, the CCL system continuously modifies the suspension, steering, braking, and other vital components based on this data. To restore stability, the system might, for example, alter engine power, change the suspension, or apply brakes to particular wheels if it notices a loss of traction during a turn.

The Advantages of Chassis and Traction Control Systems (TCS)

Logic of Control (CCL)

Numerous benefits that greatly enhance vehicle performance, safety, and stability are provided by both TCS and CCL. These technologies make modern cars more reliable and flexible for the driver by improving their performance in a variety of driving situations.

Traction control systems (TCS) advantages

Enhanced Traction: Even in slick weather like rain or snow, TCS makes sure the car keeps its maximum traction by minimizing wheel spin. As a result, the driver can continue to steer the car without fear of losing control.

Better Acceleration: TCS helps to make acceleration more controlled and smooth. TCS ensures that power is delivered to the road effectively during rapid acceleration by preventing wheel spin, which improves vehicle performance.

Decreased Skidding Risk: TCS improves overall vehicle stability by reducing the chance of skidding during abrupt turns by enhancing traction and managing wheel spin.

Enhanced Off-Road Capability: TCS makes sure the car maintains traction when driving off-road or on uneven terrain, assisting drivers in navigating difficult situations.

Enhanced Safety: By reducing traction loss, particularly during fast twists or emergency maneuvers, TCS greatly increases safety. This facilitates drivers’ ability to keep control, especially under challenging circumstances.

Easy to use: TCS is a completely automated system that doesn’t require any input from drivers, thus drivers of all experience levels can use it. Overall driving safety and confidence are raised as a result.

Chassis Control Logic’s (CCL) advantages

Better Management: CCL improves a car’s handling and cornering skills by modifying the steering and suspension. This makes driving more responsive and smooth, especially when negotiating tight curves or difficult road conditions.

Enhanced Stability: CCL enhances stability, especially when navigating curves or performing fast turns, by coordinating with other systems like ESC and ABS. This lessens the chance of skidding or rollover, particularly in higher cars like trucks and SUVs.

Optimal Braking: By ensuring that the vehicle’s braking power is distributed evenly across all wheels, ABS and EBD work together to improve brake efficiency and shorten stopping distances.

Customized Driving Modes: Certain cars with CCL include driving modes that can be changed, such as sport, comfort, and eco. To suit the driver’s preferences and the state of the road, these modes modify the throttle sensitivity, steering response, and suspension firmness.

Improved Vehicle Control: By enhancing vehicle control, features like torque vectoring and variable steering assistance make it simpler to handle challenging driving situations.

Decreased Tire Wear: CCL helps avoid uneven tire wear by more uniformly transmitting forces over all four wheels, which extends tire life.

The disadvantages of chassis control logic (CCL) and traction control systems (TCS)

Although TCS and CCL have many benefits, these systems do have certain disadvantages.

Traction control systems (TCS) disadvantages

Diminished Power Output: TCS may briefly lower engine power or apply braking force when it steps in to limit wheel spin. This may cause a brief drop in acceleration performance, which in some circumstances — particularly for high-performance cars — may not be acceptable.

Loss of Driver Control: For seasoned drivers who would rather manually control traction, TCS intervention may occasionally feel excessively harsh. A sense of lost control may result from this.

Limited Off-Road Effectiveness: Although TCS works well on paved roads, it may not operate as well off-road, especially when negotiating obstacles that need wheel spin for traction.

False Activation: On rare occasions, TCS may mistakenly identify wheel slips in traffic or under mild acceleration, resulting in needless interventions that could irritate drivers.

Cost and Complexity: Production costs and vehicle complexity are raised by the incorporation of TCS systems. Over time, this may lead to increased maintenance expenses.

Chassis Control Logic (CCL) drawbacks

Enhanced Intricacy: The combination of many control systems, such as adaptive suspension, ABS, and ESC, can result in a complicated configuration that can be expensive and challenging to fix.

Dependency on Sensors: Electronic components and sensors are crucial to CCL. The whole functionality of the system may be impacted if any of these parts malfunction, raising safety issues.

Driver Adaptation: When the system modifies the handling or responsiveness of a vehicle, some drivers may find it difficult to become used to the new behavior.

Restricted Off-Road Capability: Although CCL improves handling and stability on roads, it might not provide the same advantages off-road, where other factors are in work.

Environmental Impact: Non-electric vehicles may use less fuel due to the increased energy consumption caused by the additional electronic components needed for CCL systems.

Conclusion:

To sum up, modern cars have been transformed by revolutionary technology like Chassis Control Logic (CCL) and Traction Control Systems (TCS).

Together, these systems enhance vehicle performance, safety, and stability, enabling cars to confidently traverse a variety of road conditions.
