Device for support of coupling trailer to trailer coupling of motor car e.g. passenger car, controls relative movement of trailer coupling of motor car based on determined relative position of trailer coupling of trailer

摘要

The device has ultrasonic sensor that determines the relative position of trailer coupling of trailer (18) with respect to trailer coupling (12) of motor car (10). The relative movement of trailer coupling of motor car is controlled based on determined relative position of trailer coupling of trailer. An independent claim is included for method for coupling trailer to motor car.
