The invention relates to a vehicle braking feedback torque compensation method and system and a vehicle, and the method comprises the steps: S1, responding to the power-on of the vehicle, and obtaining the state information of the vehicle; s2, when the state information meets a preset condition, obtaining a target feedback torque and a current torque; and S3, pressure closed-loop control is conducted on a motor according to the target feedback torque and the current torque, so that when the vehicle is in the full-power working condition, the vehicle is pressurized, and then brake feedback torque compensation is provided for the vehicle. According to the technical scheme, the braking feedback torque is compensated under the full-power working condition, the consistency of braking drivability under the full working condition is ensured, and the driving experience is good.

    本申请涉及一种车辆制动回馈扭矩补偿方法、系统及车辆,方法包括:S1、响应于车辆上电,获取所述车辆的状态信息;S2、当所述状态信息满足预设条件时,获取目标回馈扭矩和当前扭矩;S3、根据所述目标回馈扭矩和所述当前扭矩对电机进行压力闭环控制,以当所述车辆处于满电工况时为所述车辆增压进而为所述车辆提供制动回馈扭矩补偿。本申请的技术方案,在满电工况下补偿制动回馈扭矩,确保全工况下制动驾驶性的一致性,驾驶体验好。
