The invention belongs to the technical field of automobiles, and discloses an electric vehicle braking control method and a vehicle, and the electric vehicle braking control method comprises the following steps: monitoring the working condition of the vehicle, circularly judging whether the vehicle meets an energy recovery condition according to a set step length, and if the vehicle meets the energy recovery condition, recovering braking energy; the braking energy recovery comprises the steps that whether the current vehicle speed is larger than or equal to the set vehicle speed or not is judged, and if yes, the current standard braking torque and the current vehicle target acceleration are determined according to the current vehicle speed and the current brake pedal opening degree; determining a current first brake torque correction coefficient according to a difference value between the current actual acceleration of the vehicle and the current target acceleration of the vehicle; determining a current target braking torque according to the current first braking torque correction coefficient and the current standard braking torque; and the motor torque is controlled to be adjusted towards the current target braking torque.
本发明属于汽车技术领域,公开了一种电动车辆制动控制方法及车辆,电动车辆制动控制方法包括:监测车辆工况,按照设定步长循环判断车辆是否满足能量回收条件,如果车辆满足能量回收条件,则进行制动能量回收;制动能量回收包括:判断当前车速是否大于或等于设定车速,如果当前车速大于或等于设定车速,则根据当前车速及当前刹车踏板开度确定当前标准制动扭矩和当前车辆目标加速度,并且根据当前车辆实际加速度与当前车辆目标加速度的差值确定当前第一制动扭矩修正系数;根据当前第一制动扭矩修正系数和当前标准制动扭矩确定当前目标制动扭矩;控制电机扭矩向当前目标制动扭矩进行调整。
