The invention discloses an automobile limping mode control circuit which comprises a first switch module, a second switch module, a third switch module, a one-way conduction module and a voltage division circuit. The output end of the voltage division circuit is electrically connected with the control end of the first switch module; the first end of the first switch module is electrically connected with a first voltage end, and the second end of the first switch module is electrically connected with the control end of the second switch module and the control end of the third switch module. The first end of the second switch module is electrically connected with the control end of the first switch module, and the second end of the second switch module is electrically connected with a second voltage end; the first end of the third switch module serves as the output end of the automobile limping mode control circuit, and the second end of the third switch module is electrically connected with the second voltage end. When the automobile breaks down, the fault output end of the automobile outputs a fault signal, so that the first switch module, the second switch module and the third switch module are switched on, and the limping mode is triggered. The circuit structure is simple, and automobile cost is reduced.

    本发明公开了一种汽车跛行模式控制电路,包括第一开关模块、第二开关模块、第三开关模块、单向导通模块和分压电路;分压电路的输出端与第一开关模块的控制端电连接;第一开关模块的第一端与第一电压端电连接,第一开关模块的第二端分别与第二开关模块的控制端和第三开关模块的控制端电连接;第二开关模块的第一端与第一开关模块的控制端电连接,第二开关模块的第二端与第二电压端电连接;第三开关模块的第一端作为汽车跛行模式控制电路的输出端,第三开关模块的第二端与第二电压端电连接。汽车出现故障时,汽车的故障输出端输出故障信号,使得第一开关模块、第二开关模块和第三开关模块导通,触发跛行模式。电路结构简单,降低汽车成本。
