SYSTEM DESCRIPTION

1. DESCRIPTION

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 power steering effort.

The power steering ECU determines the direction and the amount of assisting power in accordance with the vehicle speed signals and signals from the power steering torque sensor and motor rotation angle sensor. As a result, steering effort is controlled to be light during low speed driving and moderately high during high speed driving.

2. FUNCTION OF MAIN COMPONENTS

The power steering ECU, power steering torque sensor, power steering motor and motor rotation angle sensor are built into the steering column assembly.
