Convenience electronics

from Wikipedia, the free encyclopedia

For convenience electronics include all electrical and electronic components and assemblies in motor vehicles that the comfort increase of the occupant or the overall safety of the vehicle.

These are e.g. B. central locking , radio , telephone, heated seats , electric windows , mirror and seat memory, navigation systems , seat ventilation or massage, electric top operation ( convertible ).

The control units of the convenience electronics, also known as the convenience system, are usually connected to one another in modern motor vehicles via their own CAN bus - the so-called convenience CAN. Since this works at different speeds compared to the drive CAN (engine, transmission, ABS control unit, etc.), a gateway control unit forms the interface between the two systems, so that the vehicle speed signal from the ABS control unit is also used for calculation the speed-dependent volume increase on the radio can be used. The separation also has security reasons.
