The invention provides a vehicle energy recovery control method and system and a vehicle, and the method comprises the steps that after an energy recovery function is enabled, a VCU determines a reference vehicle speed according to the driving data of the vehicle; the VCU sends the actual wheel speed and the reference vehicle speed to the MCU; the MCU determines a target torque through a proportional-integral-derivative control strategy according to the actual wheel speed and the reference vehicle speed; wherein in the proportional integral differential control strategy, the larger the deviation value of the reference vehicle speed and the actual wheel speed is, the smaller the target torque is; and the MCU controls the motor torque according to the target torque. By means of the mode, only communication between the two controllers is achieved, the torque response time is shortened, and slipping of wheels can be controlled more quickly; besides, the torque is controlled in real time according to the deviation value of the reference vehicle speed and the actual wheel speed, when the vehicle slips, the vehicle speed is slowly converged by reducing the energy recovery torque, the convergence of the speed change is good, and the stability of the vehicle is improved.

    本发明提供一种车辆能量回收控制方法、系统及车辆,该方法包括:在能量回收功能启用后,VCU根据车辆的行驶数据,确定参考车速;VCU将实际轮速和参考车速发送到MCU;MCU根据实际轮速和所述参考车速,通过比例积分微分控制策略确定目标扭矩;其中,在比例积分微分控制策略中,参考车速和实际轮速的偏差量越大时,目标扭矩越小;MCU根据目标扭矩控制电机扭矩。通过本方式,只有两个控制器之间的通讯,扭矩响应时间缩短,车轮的打滑可以得到更快的控制;另外,根据参考车速和实际轮速的偏差量进行实时控制扭矩,在车辆发生打滑现象时,通过减少能量回收扭矩使车辆速度慢慢收敛,速度变化的收敛性好,提高车辆的稳定性。
