The invention discloses a windscreen wiper driving device, a windscreen wiper control system and a vehicle. The windscreen wiper driving device comprises a control unit, a first switch tube, a second switch tube and an anti-backflow unit. A controlled end of the first switch tube is connected with a first control signal output end of the control unit, and a first end of the first switch tube is used for being connected with a power supply; the first end of the anti-backflow unit is connected with the second end of the first switch tube, and the second end of the anti-backflow unit is used for being connected with the low-speed driving end of the wiper motor; a controlled end of the second switch tube is connected with a second control signal output end of the control unit, a first end of the second switch tube is used for being connected with a power supply, and a second end of the second switch tube is used for being connected with a high-speed driving end of the wiper motor; wherein the anti-backflow unit is used for preventing current of the high-speed driving end from flowing backwards to the first switch tube from the low-speed driving end when the wiper motor is in a high-speed working state. In this way, the working reliability of the wiper motor can be improved.

    本申请公开了一种雨刮驱动装置、雨刮控制系统及车辆,雨刮驱动装置包括:控制单元、第一开关管、第二开关管和防倒灌单元。第一开关管的受控端与控制单元的第一控制信号输出端连接,第一开关管的第一端用于与电源连接;防倒灌单元的第一端与第一开关管的第二端连接,防倒灌单元的第二端用于与雨刮电机的低速驱动端连接;第二开关管的受控端与控制单元的第二控制信号输出端连接,第二开关管的第一端用于与电源连接,第二开关管的第二端用于与雨刮电机的高速驱动端连接;其中,防倒灌单元用于在雨刮电机处于高速工作状态时防止高速驱动端的电流从低速驱动端倒灌至第一开关管。通过该方式,能够提高雨刮电机工作的可靠性。
