Electric power steering introduction

What is the use of 1?


Turning directions, parking, and turning around are easier and more convenient.

2 advantages


· Power assist is provided by the electric booster, which does not directly occupy the engine power. It also saves components such as pulleys mounted on the engine, which relatively saves energy consumption.

Compact and lightweight, it is conducive to layout and assembly. There are no oil pumps and other components, and later there is no need to change the booster oil to save money.

· Various manufacturers are gradually gaining popularity, which is the development trend of the power steering system.

3 technical principles


Electric power steering system, or EPS, is the abbreviation of English Electric Power Steering. The system is powered directly by an electric power assist, eliminating the power steering oil pumps, hoses, hydraulic oil, conveyor belts, and pulleys mounted on the engine necessary for hydraulic power steering systems.


When the driver steers the steering wheel, the torque sensor detects the steering wheel and the magnitude of the torque, and sends the voltage signal to the electronic control unit. The electronic control unit detects the torque signal and the direction of rotation according to the torque sensor. And vehicle speed signals, etc., to the motor controller instructions, so that the motor output corresponding size and direction of the steering assist torque to generate auxiliary power. When the car does not turn, the electronic control unit does not issue a command to the motor controller and the motor does not operate.

There are three types of electric power steering systems: steering shaft assist, gear assist, and rack assist.
