The invention belongs to the technical field of relay control, and particularly relates to a vehicle relay switch control system which comprises a control module, a power supply module and a latch module. The control module is used for generating a corresponding control signal according to the starting signal; the power supply module is used for ensuring the power supply of the control module and the latch module in a normal working mode or limping mode of the vehicle; the power supply module is also used for monitoring the operation state of the control module and outputting a state signal according to the operation state; the latch module is used for generating a corresponding driving signal according to the starting signal, the control signal and the state signal; when the starting signal is effective, the driving signal drives the relay to be closed; and when the starting signal is invalid, the driving signal drives the relay to be disconnected. Compared with the prior art, the on-off control system of the vehicle relay is low in hardware cost, simple and easy to realize in software strategy and higher in reliability.
