The invention discloses a braking mode switching consistency control system and a control method thereof. The braking mode switching consistency control system comprises a target braking force acquisition device, a hydraulic braking force detection device, a hydraulic braking force storage device, a braking consistency control device, a hydraulic braking force control device and a motor braking force control device. The hydraulic braking force is compensated through the motor braking force to avoid braking force impact in the braking mode switching process, and the hydraulic braking force dynamic response curves in the pressure building process or the pressure relief process corresponding to different current hydraulic braking force and target hydraulic braking force are obtained through neural network training of the pressure building data set and the pressure relief data set. The motor braking force response curve is obtained through calculation of the hydraulic braking force dynamic response curve, the compensation precision is improved, and the problem that the driving experience feeling is poor due to braking force impact generated in the braking mode switching process due to the fact that motor response lags is solved.

    本发明公开了一种制动模式切换一致性控制系统及其控制方法,包括:目标制动力获取装置、液压制动力检测装置、液压制动力存储装置、制动一致性控制装置、液压制动力控制装置和电机制动力控制装置;本发明通过电机制动力补偿液压制动力避免在制动模式切换过程中产生制动力冲击,利用建压数据集和泄压数据集神经网络训练得到不同当前液压制动力和目标液压制动力对应的建压过程或泄压过程液压制动力动态响应曲线,通过液压制动力动态响应曲线计算得到电机制动力响应曲线,提高补偿精度,避免因电机响应存在滞后导致制动模式切换过程中产生制动力冲击,造成驾驶体验感差的问题。
