POWER STEERING SYSTEM


  1. OUTLINE


    1. The Electric Power Steering (EPS) system uses a motor and a reduction mechanism that are built into the steering gear housing to generate assist torque, in order to assist the driver's steering effort.

    2. The EPS system actuates the motor only during steering when torque assist is required. As a result, the EPS system does not consume any energy during straight line driving, thus achieving fuel economy.

    3. The EPS system is driven by a high voltage (46 V). A power steering converter assembly coverts the power of auxiliary battery (12 V) and supplies to the motor.

    4. The EPS system performs control in cooperation with the brake control system. The power steering ECU assembly controls the assist torque for the motor based on the assist torque request sent from the skid control ECU assembly.
