The invention discloses a braking feedback torque distribution method and device, a vehicle controller and a vehicle, and belongs to the technical field of automobile control. The method comprises the steps that first, according to deceleration corresponding to a braking stroke and a preset deceleration threshold value, a first braking feedback torque of a first motor and a second braking feedback torque of a second motor are determined, and the efficiency of the first motor is higher than that of the second motor; secondly, acquiring running condition parameters of the vehicle; and the first brake feedback torque and the second brake feedback torque are corrected according to the driving working condition parameters, and the first corrected brake feedback torque and the second corrected brake feedback torque are obtained. According to the method, the braking expectation of a driver is considered, distribution of the braking feedback torque is considered in combination with the running working condition parameters, the probability of tire locking is reduced, the service life of tires is prolonged, the braking performance of the vehicle is improved, and the safety, stability and comfort of vehicle braking are further improved.
本发明公开了一种制动回馈扭矩分配方法、装置、车辆控制器及车辆,属于汽车控制技术领域。该方法包括:首先根据制动行程对应的减速度和预设的减速度阈值,确定第一电机的第一制动回馈扭矩与第二电机的第二制动回馈扭矩,该第一电机的效率高于第二电机;其次获取车辆的行驶工况参数;根据行驶工况参数对第一制动回馈扭矩和第二制动回馈扭矩进行修正,得到第一修正的制动回馈扭矩和第二修正的制动回馈扭矩。上述方法考虑了驾驶员的制动预期并结合了行驶工况参数来考虑制动回馈扭矩的分配,降低了轮胎抱死的概率,提高了轮胎的使用寿命和车辆的制动性能,还提高了车辆制动的安全性、稳定性和舒适性。
