| 摘要 |
The present invention relates to a steering system for the rear wheels (13,14) of a vehicle comprising an actuator (18) for steering the rear wheels (13,14), sensor unit for measuring vehicular parameters (e.g. a vehicle speed sensor (20), an accelerometer (21) and a steer angle sensor (23)) and generating signals indicative thereof, and a control system for controlling the actuator (18) comprising a processor (17) which processes the signals generated by the sensor unit (20,21,23) and controls the rear wheels (13,14) accordingly. The control system of the invention has detection unit to detect when the signals generated by the sensor unit (20,21,23) indicate that the vehicle is sliding and override unit which modifies the operation of the control system when sliding is detected.
