The invention discloses a constant speed cruise ramp compensation method and device, a storage medium and a vehicle. The method comprises the steps that after it is detected that the vehicle enters a constant speed cruise mode, target vehicle speed information, dynamic gradient information and vehicle speed error information of the vehicle are obtained; acquiring basic driving torque according to the target vehicle speed information, acquiring ramp compensation torque according to the dynamic gradient information, and acquiring vehicle speed compensation torque according to the vehicle speed error information; and controlling a motor controller to drive a motor to output driving torque according to the basic driving torque, the ramp compensation torque and the vehicle speed compensation torque. Therefore, based on the constant-speed cruise ramp compensation method, the control precision of the ramp speed can be effectively improved, the reliability and stability of vehicle constant-speed cruise are ensured, and the driving experience of a user is improved.

    本发明公开了一种定速巡航坡道补偿方法、装置和存储介质及车辆,其中,方法包括:在检测到车辆进入定速巡航模式后,获取车辆的目标车速信息、动态坡度信息、车速误差信息;根据目标车速信息获取基础驱动扭矩,根据动态坡度信息获取坡道补偿扭矩,并根据车速误差信息获取车速补偿扭矩;根据基础驱动扭矩、坡道补偿扭矩和车速补偿扭矩,控制电机控制器驱动电机输出驱动扭矩。由此,基于本发明实施例的定速巡航坡道补偿方法,可以有效提高坡道车速的控制精度,确保车辆定速巡航的可靠性和稳定性,提升用户的驾乘体验。
