Electric Power Steering Market: Taking a Smooth Turn

With a shift in the automotive industry toward more fuel-efficient and smarter vehicles, the electric power steering market has a huge potential to grow in the upcoming years. Consumers have started preferring the electric power steering (EPS) system over the traditional Hydraulic Power Steering (HPS) system when they decide to buy a new vehicle, as EPS provides an enhanced and smooth driving experience.

The EPS system does not require a mechanical connection between the steering and the wheels. In the electric power steering system, when the steering is turned, a torque sensor on the steering column detects this movement and sends information to the Powertrain Control Module (PCM), which is the control unit of the car. This control unit then sends electricity to the motor placed at the end of the steering column. Once the motor receives the correct voltage signal, its gears start rotating, which controls the movement of the car's rack and ensures that the front wheels move in the desired direction!

Integration with other Automotive Systems: One of the biggest benefits of adopting the EPS system is that it can be integrated with other automotive systems, which is the need of the hour. Lane departure warning (LDW), automated parking and electronic stability control (ESC) are recent trends of the automotive industry that are compatible with the EPS system. The diverse applications of EPS in other automotive systems increase vehicles’ overall safety and enable more sophisticated steering assistance.

Integration with Autonomous Driving System: Another major industry trend is autonomous driving systems, and the EPS is crucial here, too! An Autonomous Driving System (ADS) requires electric power steering, as it allows the car to steer itself without the driver's assistance.

Why the Electric Power Steering Market is Growing: Advantages Offered by Electric Power Steering System

The EPS system is becoming popular as it offers many advantages when compared to the traditional hydraulic power steering system. HPS has a complicated design and consumes more power than electric power steering. Growing environmental concerns have given rise to the adoption of EPS as they consume less fuel than their traditional counterpart. According to some estimates, EPS can save up to 90% of the energy used by the HPS system. Moreover, the EPS system does not require hydraulic fluids, which results in reduced maintenance costs. Electric power steering also helps in reducing the weight of the vehicle as it uses electric motors instead of hydraulic pumps.

Governments and regulatory organizations in many countries have enforced strict guidelines related to CO2/CO emissions, fuel efficiency and vehicle safety, that mandate manufacturers to integrate cutting-edge technologies in steering mechanisms. For example, in case of frontal impact, collapsible electric power steering (CEPS) collapses the steering column and provides additional safety to the driver by reducing the risk of chest and head injuries.

How Traction Control Works

Traction control is a modern technology designed to improve the grip between a vehicle and the road. It is most commonly used in cars, but can also be found in motorcycles, ATVs, and other vehicles.

Traction control works by detecting when a wheel is slipping. It does this by monitoring the speed of each wheel, and comparing it to the speed of the other wheels. If there is a difference in speed, it indicates that one wheel is slipping.

When this is detected, the traction control system will apply the brakes to the slipping wheel. This reduces the speed of the wheel and helps to restore grip. It also reduces the amount of power being sent to the wheel, helping to prevent further slippage.

In addition, traction control also helps to improve vehicle stability. It can detect when a vehicle is beginning to skid, and will apply the brakes to help keep the vehicle in control. This allows drivers to maintain control of their vehicle in less than ideal conditions.

Traction control can be found in many modern vehicles, and is designed to help improve vehicle performance and safety. By reducing wheel slip and improving vehicle stability, it can help drivers stay in control and maintain better control of their vehicles.
