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.

    本发明属于继电器控制技术领域,具体涉及一种车辆继电器的开关控制系统,包括:控制模块、供电模块和锁存模块;控制模块,用于根据启动信号生成对应的控制信号;供电模块,用于在车辆正常工作模式或跛行模式下保证所述控制模块和所述锁存模块的供电;供电模块还用于监控所述控制模块的运行状态,并依据运行状态输出状态信号;锁存模块,用于依据所述启动信号、所述控制信号和所述状态信号生成对应的驱动信号;且在所述启动信号为有效时,所述驱动信号驱动继电器闭合;在所述启动信号为无效时,所述驱动信号驱动继电器断开。本发明的车辆继电器的开关控制系统相较于传统技术,硬件成本低,且软件策略简单易实现,具有更高的可靠性。
