12.4.4. The amplifier of a steering - the general information
Operation of the electroamplifier of the steering (EPAS) which has been built in a steering column, the special block operates, being based on data on effort and an angle of rotation of a steering wheel, and also about speed of the car.
If EPAS works during the long period, the EPAS control unit reduces its return that э / the motor did not overheat.
At malfunction emergence in an electric chain the EPAS control unit passes to emergency operation, disconnecting э / the motor. Thus on the dashboard joins corresponding To/l. Information on malfunction can be received by means of the diagnostic device since the block management of EPAS is connected to the tire CAN.
For strengthening of the torque transferred to a steering shaft from э / the EPAS motor, reduktsionny transfer is built in assembly of a steering column.
