The invention discloses a vehicle parameter adjusting method and device, and belongs to the field of vehicle control. The method includes determining a wheel end demand torque of the vehicle based on at least one of a driving mode, a driving parameter, or a system request of the vehicle; determining a driving mode based on vehicle parameters of the vehicle, and determining a wheel end actual torque of the vehicle by using the driving mode and the vehicle parameters; calculating a deviation value between the actual torque of the wheel end and the required torque of the wheel end, and determining adjustment parameters of the vehicle under the condition that the deviation value meets an adjustment condition; and adjusting the vehicle based on the adjustment parameter. According to the method, the actual wheel end torque of the vehicle is calculated through the multiple vehicle parameters in the different driving modes, and the accuracy of the determined actual wheel end torque is improved; under the condition that the deviation value of the actual wheel end torque and the wheel end demand torque of the vehicle meets the adjusting condition, the adjusting parameters of the vehicle can be determined, the vehicle is controlled through the adjusting parameters, and the stability and safety of the vehicle are improved.

    本申请公开了一种车辆参数的调整方法和装置,属于车辆控制领域。方法包括:基于车辆的驾驶模式、行驶参数、或者系统请求中的至少一种确定车辆的轮端需求扭矩;基于车辆的车辆参数确定驱动模式,利用驱动模式和车辆参数确定车辆的轮端实际扭矩;计算轮端实际扭矩与轮端需求扭矩的偏差值,在偏差值满足调整条件的情况下,确定车辆的调整参数;基于调整参数对车辆进行调整。本申请在不同的驱动模式下利用多个车辆参数计算车辆的轮端实际扭矩,提高了确定的轮端实际扭矩的准确性;在车辆实际轮端扭矩与轮端需求扭矩的偏差值满足调整条件的情况下,可以确定车辆的调整参数,利用调整参数控制车辆,提高车辆的稳定性和安全性。
