POWER STEERING SYSTEM GENERAL

OUTLINE

1. A vehicle speed sensing type Electric Power Steering (EPS) system is used.

2. A rack and pinion type steering gear assembly is used.

3. The EPS system uses a power steering motor, a power steering torque sensor and a reduction mechanism that are built into the steering column assembly to generate assist torque, in order to assist the driver steering effort.

4. The EPS system activates the power steering motor only when the driver turns the steering wheel. As a result, no energy is consumed when the vehicle is going straight, enhancing fuel economy.

5. Vehicle Dynamics Integrated Management (VDIM) or Enhanced-Vehicle Stability Control (VSC) performs integrated control of the brake control and the EPS systems. The power steering ECU controls the assist torque for the power steering motor based on the assist torque request sent from the skid control ECU.
