LOAD DRIVING SYSTEM FOR VEHICLE, SIGNAL OUTPUT DEVICE, AND LOAD DRIVING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a load driving system for a vehicle capable of synchronously driving synchronous drive electric loads without disposing a synchronous signal transmission cable from a signal output device to respective load driving devices in the load driving system for the vehicle allowing the multiple load driving devices to independently control the driving of the synchronous drive electric loads respectively. SOLUTION: This load driving system 1 for the vehicle is so constituted that a combination switch 29 simultaneously outputs drive command signals to a right-side front ECU 3, a left-side front ECU 5, and a rear ECU 7 respectively. The respective ECUs start load driving controls based on receiving timings of the driving command signals so as to synchronously drive the same type of synchronous electric loads independently drive-controlled respectively. Thereby each ECU can control the driving of each synchronous electric load synchronously with the other ECUs.
