The invention discloses an electric vehicle galloping prevention and control system, and belongs to the field of galloping prevention and control, the electric vehicle galloping prevention and control system comprises an unlocking module, after the unlocking module is triggered, an electric vehicle enters a galloping monitoring state, and the system supervises an output signal in real time to obtain a real-time signal; a linear safety range of an output signal under safe driving is preset in the system; when the real-time signal exceeds the linear safety range and no brake signal sudden change influence exists, the controller controls the speed regulation signal to carry out regulation; otherwise, the speed regulation signal output of the controller is not influenced. According to the scheme, the output signal is supervised in real time, the state of linear disturbance caused by sudden change of the output signal in a short time can be rapidly distinguished according to the preset linear safety range, and when a nonlinear signal is generated and sudden change is not caused by a brake signal, rapid braking can be achieved, a speed regulation signal can be controlled and adjusted, and the phenomenon of galloping is reduced; and the parking and driving safety is effectively guaranteed.
本发明公开了一种电动车飞车防控系统,属于飞车防控领域,一种电动车飞车防控系统,包括开锁模块,开锁模块触发后,电动车进入飞车监控状态,系统对输出信号进行实时性监督,得到实时信号;系统内预设有安全行驶下,输出信号的线性安全范围;当实时信号超出线性安全范围,且未有刹车信号突变影响时,控制器控制调速信号进行调整;否则,控制器的调速信号输出不受影响。本方案实时对输出信号监督,并根据预设线性安全范围,能快速对输出信号在短时间内突变造成线性扰乱的状态进行辨别,当产生非线性信号,且不是由刹车信号引起的突变时能快速制动,控制调整调速信号,降低“飞车”现象发生,有效保障驻车和行驶安全。
