The invention discloses a motor-assisted braking method for an electric vehicle in emergency, which is characterized in that on the premise of not increasing the hardware investment of the vehicle, the vehicle is judged to be in a relatively emergency condition through the release rate of an accelerator pedal, auxiliary braking is provided through a motor in the emergency condition, and a driver is transferred from the accelerator pedal to a brake pedal, so that the driver can brake the vehicle in the emergency condition. The vehicle is judged to be in an emergency condition through the release speed of the accelerator pedal, the motor is controlled to perform energy recovery with the maximum or larger energy recovery intensity, the vehicle begins to slow down, the time of a driver from finding the emergency condition to starting braking of the vehicle is shortened, or the injury and economic loss of passengers after the vehicle is collided are reduced, and the safety of the vehicle is improved. And the safety of the vehicle in an emergency is improved.
本发明公开了一种用于电动车紧急情况下电机辅助制动方法,在不增加车辆硬件投入的前提下,通过加速踏板的松开速率来判断车辆处于较为紧急的情况,在紧急的情况下通过电机来提供辅助的制动,驾驶员从加速踏板转移到制动踏板,通过加速踏板的松开速率来判断车辆处于较为紧急的情况,并控制电动机以最大或较大的能量回收强度进行能量回收,让车辆开始减速,缩短驾驶员从发现紧急情况到车辆开始制动的时间,或降低车辆碰撞后乘员的伤势、经济损失,提高了车辆在紧急情况下的安全性。
