The embodiment of the invention discloses an automobile electronic pump driving control circuit and an automobile electronic module. The control circuit comprises a first logic gate, a first level conversion circuit, a first pull-up resistor, a second logic gate, a second level conversion circuit and a second pull-up resistor. And the first level conversion circuit and the second level conversion circuit respectively output a first driving signal and a second driving signal which are completely opposite logically so as to drive the electronic pump to continuously operate. According to the embodiment of the invention, the problem that a user cannot effectively control the electronic pump due to the fact that the electronic pump enters a paralyzed state when an existing vehicle-mounted control system breaks down is solved. Under the working condition that the vehicle-mounted control system breaks down, short-time effective control over the electronic pump can be achieved, and vehicle running and user personal safety risks caused by control failure of the electronic pump can be effectively avoided.

    本发明实施例公开了一种汽车电子泵驱动控制电路和汽车电子模块。控制电路包括第一逻辑门、第一电平转换电路、第一上拉电阻、第二逻辑门、第二电平转换电路和第二上拉电阻,在第一PWM调速控制信号和第二PWM调速控制信号失效后,第一电平转换电路和第二电平转换电路分别输出逻辑上完全相反的第一驱动信号和第二驱动信号,以驱动电子泵持续运行。本申请实施例解决了现有车载控制系统本身发生故障会导致电子泵进入瘫痪状态,进而使用户无法对电子泵进行有效控制的问题。在车载控制系统发生故障的工况下,本发明实施例不仅能够实现对电子泵的短时有效控制,还能有效规避因电子泵控制失效而产生的车辆行驶及用户人身安全风险。
