The invention relates to a braking energy recovery torque coordination control method and device, a vehicle and a medium, and the method comprises the steps that the actual working condition of the vehicle is recognized; when the actual working condition is the preset working condition, whether the vehicle meets the preset energy recovery condition while executing the braking operation or not is judged; and if the vehicle executes the braking operation, the vehicle is controlled to enter a braking energy recovery torque coordination mode, and an electro-hydraulic coordination type energy recovery device is controlled to adjust the driving wheel slippage rate based on the rapid torque rise request value. The vehicle can be controlled to enter the braking energy recovery torque coordination mode according to the actual working condition of the vehicle in combination with the energy recovery condition and the like, the CRBS module actively guides the braking feedback torque to exit according to a certain gradient, the feedback torque is prevented from being suddenly changed, meanwhile, feedback torque control is preposed to the CRBS module, torque control is more efficient, and the service life of the vehicle is prolonged. Therefore, the forward rushing feeling of the vehicle is avoided, the safety and reliability of the vehicle are effectively improved, and the driving experience of a user is improved.
本申请涉及一种制动能量回收扭矩协调的控制方法、装置、车辆及介质,其中,方法包括:识别车辆的实际工况;在实际工况为预设工况时,判断车辆是否执行制动操作的同时达到预设能量回收条件;如果车辆执行制动操作,则控制车辆进入制动能量回收扭矩协调模式,控制电液协调式能量回收装置基于快速升扭请求值调整驱动轮滑移率。本申请可根据车辆的实际工况,结合能量回收条件等,控制车辆进入制动能量回收扭矩协调模式,由CRBS模块主动引导制动回馈扭矩按一定梯度退出,防止回馈扭矩突变,同时将回馈扭矩控制前置至CRBS模块,使得扭矩控制更加高效,从而避免车辆前冲感,有效提升了车辆的安全性和可靠性,改善了用户的驾乘体验。
