The invention relates to a windscreen wiper driving circuit, a windscreen wiper control system and a vehicle. The windscreen wiper driving circuit comprises a driving module, a signal receiving module and a latch module. Wherein the input end of the driving module is electrically connected with the output end of the wiper motor; the output end of the driving module is grounded; the output end of the signal receiving module is electrically connected with the control end of the driving module; and the latch module is electrically connected with the control end of the driving module. The signal receiving module is used for controlling the driving module to be switched on after receiving a wiper motor starting signal and controlling the driving module to be switched off after receiving a wiper motor switching-off signal; and the latch module is used for latching the potential of the control end of the driving module when the signal receiving module has no signal input. The current working state of the windscreen wiper driving circuit can be latched, when no signal is input due to the situation that the external controller is reset and the like, the windscreen wiper can be kept in the original working state, and the use experience of a user is improved.
本公开涉及雨刮驱动电路、雨刮控制系统及车辆,雨刮驱动电路包括驱动模块、信号接收模块和锁存模块。其中,驱动模块的输入端与雨刮电机的输出端电连接;驱动模块的输出端接地;信号接收模块的输出端与驱动模块的控制端电连接;锁存模块与驱动模块的控制端电连接。信号接收模块用于在接收雨刮电机开启信号后控制驱动模块导通,在接收雨刮电机关闭信号后控制驱动模块关闭;锁存模块用于在信号接收模块无信号输入时,锁存驱动模块的控制端的电位。本公开可以锁存雨刮驱动电路当前的工作状态,在外部控制器发生复位等情况导致无信号输入时,可以使雨刮保持原有工作状态,提高用户使用体验。
