System for data transmission in motor vehicle with a control facility having at least one transceiver and bus system so that control facility across transceiver and bus system exchanges

摘要

The system for data transmission is designed with a bypass facility (14), which with the bypassing of the control facility (16), depending on a switching facility signal (11) transmits an activation signal (15) to the transceiver (18) for activating the transceiver and-or the bus system. The bypass facility (14) is a monoflop, timer or waking signal generator, to which the switching facility signal (11) is supplied, and which as output signal, the activation signal (15) is transmitted to the transceiver (18).
