An object sensing device and method for a motor vehicle utilizes one or more transmitter/receiver pairs to obtain a reflex signal from an object from an object situated in front of the motor vehicle in terms of the driving directions. In a first operating mode for clear visibility, a reflex signal is emitted for the object when it is standing still or driving more slowly relative to the motor vehicle containing the device. In a second operating mode for poor visibility the reflex signal is additionally emitted when the object is sensed as coming toward the motor vehicle.

In a radio signal receiver for motor vehicles with a radio receiver with an RDS decoder for digital signals, convertible via a table into traffic information, the signals can be forwarded from the decoder via a data link to a navigation system provided with a route data storage which generates the traffic information from the signals.

In a method for avoiding a collision of a motor vehicle and an obstacle, in which the output signal of a ranging device with several scanning beams emitted in a fan shape toward the front, is received by a receiver and analyzed by an analysis unit connected thereto, the transmitting frequency for scanning beams on the inside of the curve is selected to be higher than for scanning beams on the outside of the curve.

A door lock for motor vehicles having a control element which is driven by an electric motor, is controlled by an electronic control unit and can be moved, upon a control signal emitted by a transmitter, into a position which at least prepares the opening of the door lock. An energy accumulator, which is independent of the wiring of the motor vehicle and which, as required, can be connected to a signal receiver, is assigned to the electronic control system so that the signal receiver will then activate the control element directly.

In a method for avoiding a collision of a motor vehicle with an obstacle, in which the output signal from a distance measuring device with a plurality of scanning beams emitted fanwise in and beside the motion path of the motor vehicle is fed to an evaluation unit, the output signal from a steering angle sensor is additionally fed to the evaluation unit. The motion path of the motor vehicle is calculated in the evaluation unit and the obstacle is evaluated in terms of the motion path of the motor vehicle. The obstacle is taken into account only if it enters the motion path of the motor vehicle.

A seat occupancy switching device for motor vehicles having a sensor responding to seat occupancy and an analysis circuit which emits a signal when a seat is occupied. The sensor is a lateral-force-sensitive cable which is arranged in the area of the seat surface. This cable provides a plurality of signal changes occurring continuously during seat occupancy. The analysis circuit registers each change of the sensor output signal as seat occupancy information. This analysis circuit includes a processor that receives the sensor output signal, and a monostable-circuit step.

An acceleration sensor for the automatic triggering of occupant protection systems in vehicles comprises a liquid which is moved in a housing as a function of the acceleration, with a detector which responds to a critical acceleration value. The housing is a level tube which is aligned relative to the acceleration to be determined and contains both the liquid and an indicating medium. The detector responds to the position of the indicating medium, as it moved in the liquid as a function of the acceleration.

An image-reproducing arrangement for motor vehicles, in which a real image is represented as virtual image in the field of vision of the vehicle user by means of a lens and the windshield following the lens in the path of the light rays; the real image and the lens are thereby arranged at the upper edge of the windshield. Only a mirror element is located between the lens and the windshield within the area of the surface of the instrument panel. This mirror element requires a relatively small amount of space and by reason of the relatively large distance from the lens element offers the possibility to match the virtual image falling into the eye of the vehicle user to the respective prevailing conditions.

An arrangement for the recognition of obstacles for motor vehicles with a transmitter and a receiver for electromagnetic radiation which are directed to an examination area (close range) that commences in direct proximity of the motor vehicle; a second receiver is provided which together with the transmitter is directed to a second examination area (distance or long range) which commences at a considerably greater distance in front of the motor vehicle than the close range. As a result thereof, interfering reflections at water droplets (fog) can be far-reachingly excluded.

Arrangement for the recognition of obstacles for motor vehicles

In a security installation for motor vehicles with a stationary transponder installed at the motor vehicle for producing a coded interrogating signal, with a portable transponder for receiving the coded interrogating signal and for transmitting a coded response signal and with a coded signal comparator which in case of matching of the coded response signal with an expected coded signal produces an unlocking signal, the switching signal is produced with the aid of a manually actuatable switch arranged at the motor vehicle which is connected with an actuating member provided already for the use of the motor vehicle.

A method and apparatus for testing ignition systems of internal combustion engines in motor vehicles, in which an ignition voltage signal on the primary side for one ignition operation or averaged for several ignition operations is compared with a should-be signal and the electrode distance of a spark plug is determined in that the should-be signal is taken at the beginning of a service interval and under an operating condition which at least approximately equals the actual operating condition at the point of time of the test.

A security installation with a portable transmitter and a receiver arranged at the object to be protected for an IR, respectively, UHF code signal which is changeable at least in part; alone the code signal of the transmitter can be changed upon random command and can be written into the associated storage device of the transmitter.

Security installation

A service-interval display for motor vehicles, which generates a signal when a limiting parameter value is reached. Total fuel consumption serves as the basic parameter instead of the distance travelled, previously employed. Other parameters may serve to modify the generation of the signal to cause an earlier or later warning to be displayed.

Service-interval display for motor vehicles

In an anti-theft apparatus for vehicles with wireless transmission of the code signal, the latter is suitably overlapped outside of the vehicle by a secondary signal which is not to be received in or on the vehicle. This results in an effective protection against interception of the code signal.
