The invention relates to the technical field of electric vehicle braking, and discloses an electric vehicle braking control method and an electric vehicle. The electric vehicle braking control method comprises the steps that the braking requirement of a driver is judged, and the required braking force is calculated according to the braking requirement; if the required braking force is smaller than the maximum braking force of the motor, the motor applies braking force to the front axle and starts braking energy recovery; if the required braking force is within the range of the maximum braking force of the motor and the preset braking force, the motor and a hydraulic braking system of the automobile apply braking force to a front axle at the same time; and if the required braking force is larger than the preset braking force, motor braking quits, and the hydraulic braking system applies braking force to the front axle and the rear axle at the same time. The electric vehicle is braked by adopting the electric vehicle braking control method. According to the electric vehicle braking control method, secondary triggering of the vehicle ABS can be avoided, safety is high, and the energy recovery efficiency is high. The electric vehicle is good in braking stability and high in riding comfort.

    本发明涉及电动车制动技术领域,公开一种电动车制动控制方法及电动车,电动车制动控制方法包括:判断驾驶员的制动需求,并根据制动需求计算需求制动力;若需求制动力小于电机的最大制动力,则电机对前轴施加制动力并开启制动能量回收;若需求制动力在电机的最大制动力和预设制动力范围之间,则电机和汽车的液压制动系统同时对前轴施加制动力;若需求制动力大于预设制动力,则电机制动退出,液压制动系统同时对前轴及后轴施加制动力。电动车采用上述的电动车制动控制方法进行制动。本发明提供的电动车制动控制方法能够避免车辆ABS的二次触发,安全性高且能量回收效率高。本发明提供的电动车制动稳定性好,乘坐舒适性高。
