VEHICLE CONTROL SYSTEM COMPRISING SYNCHRONIZED CONTROL CIRCUITS

Provided is a vehicle control system that appropriately performs synchronization control for a plurality of control systems when a control system configured to output a synchronization signal serving as a reference to synchronization between the control systems is changed from a stopped state to an operating state. A monitoring circuit (38) generates a command signal (S1) when only a first reset signal (Rs1) is input. The monitoring circuit (38) generates a command signal (S2) when the state in which only the first reset signal (Rs1) is input is changed to the state in which the input of the first reset signal (Rs1) is stopped. With the command signal (S1), a second clock signal (CK2) is output to a timer generator (34a) as a second timing signal (T2). With the command signal (S2), the second clock signal (CK2) generated by a second synchronization signal generating circuit (33) is output to a first synchronization signal generating circuit (23), and a third clock signal (CK3) generated by the first synchronization signal generating circuit (23) is output to a timer generator (24a) as a first timing signal (T1).
