Toyota RAV4 Service Manual: System description

  1. Description

The eps (electronic power steering) system generates torque through the operation of the motor and the reduction gear installed on the column shaft in order to assist steering effort.

The power steering ecu determines directions and the amount of assisting power in accordance with vehicle speed signals and signals from the torque sensor built into the steering column assembly. As a result, the power steering adjusts the steering effort so that it is lighter during low speed driving and heavier during high speed driving.

  1. Power steering ecu: the power steering ecu calculates assisting power based on steering torque signals from the torque sensor and vehicle speed signals from the skid control ecu.
  2. Torque sensor: the torque sensor detects the steering effort generated when the steering wheel is turned and converts it to an electrical signal.
  3. Eps motor: the eps motor is activated by the current from the power steering ecu and generates torque to assist the steering effort.
  4. Motor rotation angle sensor: the motor rotation angle sensor consists of the resolver sensor, which excels in reliability and durability. The rotation angle sensor detects the rotation angle of the motor and outputs it to the power steering ecu. As a result, it ensures efficient eps control.
