摘要： A positioning and navigation system for land vehicles features a simple and memory-conserving route entry method. Routes on maps can be specified by the junctions traversed by the route, so that entering only the junctions in memory uses much less space than prior art digital route storage systems which stored the coordinates of each point along the route. A trip progress information display shows the route vividly by using color or brightness contrast with the rest of the map. Additional direction of travel indications can be given, for example on a Head Up Display reflected off the inside of the windshield within the operator's field of view or by acoustic signals or speech-synthesized announcements. This results in particularly easy-to-follow guide to the driver or operator. Head-up displays on motor vehicles often have double images and interfering reflections on the windshield. To avoid these, arrangements of linear polarization filters or shutter foils are suggested, which have particularly high light transmission. Arrangements of filter plates on a combiner inside of the windshield are also advantageous.

摘要： 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.

摘要： In a device for measuring the distance to an obstacle, a second transmission pulse as a control measurement for an ultrasonic distance measurement is transmitted only when an echo signal has been received for a first transmission pulse. In addition, a timing window, within which the expected echo signal falls when it is reflected by an obstacle, is created. In this manner, interference signals are advantageously suppressed and the measuring time is accelerated, so that for an application in a motor vehicle to measure distance, a current measured value is always known while the vehicle velocity and the path covered are taken into consideration.
