Zusammenfassung:A vehicle steering aid system for use with a vehicle 10 and trailer 12 combination, comprises a control unit 16, vehicle movement sensors, proximity sensors 18, 20, 22, 24, 26, 28, video cameras 30, 32, 34, 36, and a user interface 54. The vehicle movement and proximity sensors enable a digital map of the car surroundings to be formed. The view from the video cameras is displayed on a touch screen which is used to input a desired parking destination. Indication of target destination may also be achieved by using a joystick. The control unit then formulates a best route and delivers both visual and audio steering cues via a screen and indicators. The steering cues incorporate a proportional element to indicate the amount of steering required. The invention claimed herein relates to a jack-knife detection means, included in the steering aid system, wherein sensors monitor the trailer angle, rate of change in trailer angle and distance moved by the vehicle. When the trailer angle exceeds a predetermined angle then an alarm sounds and corrective steering cues are issued. As the user manoeuvres the vehicle, the digital map and relative position of the vehicle are continually updated and steering correction cues delivered via the interface.
