Automobile onboard electrical supply network for control devices, has master control device controlling switching of slave control devices from stand-by mode to normal operating mode

摘要

The network has a power source (4), a master control device (1), a power distribution circuit (14) and at least one slave control device (2,3) operating at the minimum power level required for communication with the master control device in a stand-by mode and responding to a wake-up signal from the master control device for switching to a normal operating mode with a higher operating voltage. The communication between the master control device and the slave control devices can be effected via an information network (15).
