The invention relates to an intelligent continuous braking method and system for an electric vehicle, which is applied to the technical field of electric vehicles, and comprises the following steps: acquiring the pressure of a mechanical brake of the electric vehicle and the acceleration value in the real-time driving process, and comparing the acceleration value corresponding to the preset pressure of the mechanical brake with the real-time acceleration; whether the mechanical brake breaks down or not is judged, if the real-time acceleration value is smaller than the acceleration value corresponding to the mechanical brake pressure, it is indicated that the mechanical brake fails or breaks down, reverse current is compensated for the vehicle motor, the vehicle motor provides reverse electromotive force, and the reverse electromotive force can compensate the acceleration value during mechanical brake; the acceleration during mechanical braking is equal to the acceleration value corresponding to the pressure borne by the mechanical braking, and potential safety hazards caused by failure of the mechanical braking are avoided.
本发明涉及一种电动车智能连续刹车方法及系统,应用于电动车技术领域中,包括:通过获取电动车的机械刹车的压力以及实时行驶过程中的加速度值,根据预设的机械刹车的压力所对应的加速度值与实时加速度进行比对,判断机械刹车是否出现故障,若实时加速度值小于该机械刹车压力所对应的加速度值,表明机械刹车失灵或出现故障,通过对车辆电机补偿反向电流,使得车辆电机提供反向电动势,反向电动势会补偿机械刹车时的加速度值,使得机械刹车时的加速度与机械刹车受到的压力所对应的加速度值相等,避免因机械刹车失灵而导致安全隐患的发生。
