Abstract
An auxiliary back-up and trailer coupling device for motor vehicles includes ultrasonic sensors mounted on the motor vehicle. The ultrasonic sensors transmit and receive sound waves, and are linked to a control and display device. The device permits the position of a trailer unit that is equipped with a coupling device and arranged behind the motor vehicle to be exactly determined. The trailer is equipped with a coupling device, preferably a tow bar, and has an additional transmitting and receiving ultrasonic sensor.
