The invention discloses an accidental starting control circuit of an electric bicycle, and belongs to the technical field of electric bicycles. The accidental starting control circuit comprises a pressure strain circuit, a primary amplifying circuit, a secondary amplifying circuit, an electric bicycle battery pack, a power supply module, a voltage comparison circuit, a handle switch and a siliconcontrolled rectifier switching circuit. A pressure strain gauge is adopted to replace a switch, and the influence caused by poor contact or adhesion due to the switch is eliminated. The pressure strain gauge is adopted as a resistance strain gauge, the size is small, installation is convenient, the gain of an amplifier IC2 can be adjusted, a good sensitivity compensation effect is achieved, and the maintenance cost is reduced.

    本发明公开了一种电动自行车意外起步控制电路,属于电动车技术领域,包括压力应变电路、一级放大电路、二级放大电路、电动车电池组、电源模块、电压比较电路、把手开关和可控硅开关电路;解决了采用压力应变计代替开关,杜绝了由于开关引起的接触不良或粘连所带来的影响,本发明采用压力应变计为电阻应变片,体积小,安装方便,本发明可以调节放大器IC2的增益,从而起到很好的灵敏度补偿作用,减少了维护成本。
