The invention relates to a vehicle braking control method and device and a rear-drive electric vehicle. Specifically, the invention relates to a vehicle braking control method. According to the method, a front wheel state monitoring module monitors the rotating speed and acceleration of front wheels of a vehicle in real time, judges whether the vehicle passes through a deceleration strip or not and generates a deceleration strip recognition signal. According to the identification signal, the system actively cancels braking energy recovery and sliding energy recovery so as to avoid unstable deceleration caused by energy recovery. And then, the hydraulic execution control module adjusts the pressure of the hydraulic system according to the quitted energy recovery torque data so as to compensate the braking force loss caused by energy recovery quitting. According to the method, energy recovery and brake control can be dynamically adjusted, unstable deceleration caused by the deceleration strip and impact on the speed reducer are prevented, and therefore driving safety and comfort are effectively improved.

    本申请涉及一种车辆制动控制方法、装置及后驱电动汽车。具体地,本申请涉及一种车辆制动控制方法。该方法通过前轮状态监测模块实时监测车辆前轮的转速和加速度,判断车辆是否正在经过减速带,并生成减速带识别信号。根据该识别信号,系统主动取消制动能量回收和滑行能量回收,以避免因能量回收引起的减速不平稳。随后,液压执行控制模块根据退出的能量回收扭矩数据,调整液压系统压力,以补偿因能量回收退出所造成的制动力损失。该方法能够动态调整能量回收与制动控制,防止因减速带引起的减速不稳定和对减速器的冲击,从而有效提高驾驶安全性与舒适性。
