Abstract:
A vehicle electronic control system includes a first electronic control unit that completes execution of a first control process in a predetermined time, and a second electronic control unit connected to the first electronic control unit that executes a second control process inseparable from the first control process. The first electronic control unit transmits a synchronization signal at periods sufficiently less than the predetermined time. The second electronic control unit starts execution of the second control process with reference to the synchronization signal received.
