The 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 control module 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. As a result, the power steering control module adjusts the steering effort so that it is lighter during low speed driving and heavier during high speed driving.
Power Steering Control Module
The power steering control module calculates assisting power based on steering torque signals from the torque sensor and vehicle speed signals from the skid control module.
Torque Sensor
The torque sensor detects the steering effort generated when the steering wheel is turned and converts it to an electrical signal.
Power Steering Motor
The power steering motor is activated by the current from the power steering control module and generates torque to assist the steering effort.
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 control module. As a result, it ensures efficient electric power steering control.
