Control method for two or more motor vehicle control units, especially blinker or indicator light controllers, whereby the timer circuits of the two controllers are synchronized using existing control bus signals

摘要

Control method for a first (6) and at least a second (8) motor vehicle control unit each with their own clock circuits (5, 7), with each control unit intended for controlling at least one load (2, 4), especially an indicator light, that is cyclically operated. The control units are connected via a bus (10) for exchange of bus messages. At least one of the bus messages is used by the control units to correct its clocking signal so that the control units are synchronized. An independent claim is made for a motor vehicle system for synchronizing the operation of blinking indicator lights.
