The invention discloses a motor braking method and system based on brake pedal feeling. The method specifically comprises the following steps: S1, searching for a corresponding motor braking adjustment coefficient K in real time based on the current brake pedal stroke t and the current vehicle speed v; S2, obtaining an initial braking torque based on the brake pedal stroke t and the vehicle speedv; S3, correcting the initial braking torque based on the motor braking adjustment coefficient K; under the same braking stroke, the motor outputs stable braking torque at different vehicle speeds based on the motor braking torque adjustment coefficient K. The motor braking torque is adjusted based on the motor braking adjustment coefficient K, and the adjusted motor braking better meets the driving habit of a user, that is, the feeling of a brake pedal is guaranteed; on the premise that pedal feeling control is guaranteed, the driving feeling of a client is met, and braking energy of the whole vehicle can be recycled.

    本发明公开了一种基于制动踏板感觉的电机制动方法及系统,该方法具体包括如下步骤:S1、基于当前制动踏板行程t与当前车速v实时查找对应的电机制动调整系数K;S2、基于制动踏板行程t及车速v获取初始制动扭矩;S3、基于电机制动调整系数K对初始制动扭矩进行修正;在同一制动行程下,基于电机制动力矩调整系数K实现电机在不同车速下输出稳定的制动力矩。基于电机制动调整系数K对电机制动扭矩进行调整,调整后的电机制动更为满足用户的驾驶习惯,即保证了制动踏板感觉;保证踏板感觉控制的前提下,满足客户的驾驶感觉,并能够对整车进行制动能量回收。
