System Description
Major Components
The Electrical Power Steering system is composed of the following major components:
EPS CONTROL UNIT
COUNTERSHAFT
SPEED SENSORALTERNATOR
SPEEDOMETER
EPS INDICATOR
LIGHT
STEERING
SENSOR
BATTERY
POWER UNIT
MOTOR
IGNITION
SWITCH
A steering gearbox that converts rotary operation of the steering wheel into transverse operation via a rack and pinion
mechanism. Steering sensors and an actuating motor are incorporated.
A control unit that computes the optimum amount of power assistance, taking into account steering torque, steering
speed, and vehicle speed. Selfdiagnosis functions are included.
A power unit that drives the motor according to the signals from the EPS control unit. A current sensor is built in to
give feedback information to the EPS control unit. Two relays shut off the power if a problem in the system occurs.
A speed sensor, the countershaft speed sensor, send vehicle speed signal to the EPS control unit. Also the
speedometer send vehicle speed signal to the EPS control unit. Two signals are used as a double-check.
