DESCRIPTION

The NSK - EMPAS Electrical Power Assisted Steering system reduces the effort required to steer the car by using the torque produced by an electric motor. This assistance is supplied by an electric motor that applies a torque to the steering column via a gear set. This torque aids steering manoeuvres when the car is at a standstill or moving at low speed without making the steering too light during normal driving.

The electronic control unit contains a management programme which consists of a set of strategies designed to manage system control functions.

The control unit software processes incoming information to determine direction of rotation and electrical motor current. It then controls the supply of power to achieve the desired power steering effect.

The instrument panel includes an electrical steering failure warning light which comes on if there is a fault in the system.
