The invention provides a vehicle anti-skid control method and system, a vehicle and a storage medium, and relates to the technical field of vehicles. The method comprises the steps that the actual rotating speed of a motor in a vehicle is obtained; determining the target rotating speed of the motor under the current road surface; generating a torque adjusting signal at the current moment according to the rotating speed deviation value at the current moment; under the condition that the frequency of the torque adjusting signal at the current moment is larger than or equal to the safe frequency, the rotating speed deviation value at the next moment is input into a notch filter, and the corrected rotating speed deviation value at the next moment is obtained; and according to the corrected rotating speed deviation value at the next moment, a torque adjusting signal at the next moment is generated, so that the actual rotating speed of the motor is adjusted under the safe frequency, and anti-skid control is conducted on the vehicle. According to the scheme provided by the embodiment of the invention, the fluctuation in the torque adjusting signal can be adaptively eliminated while anti-slip control is performed on the vehicle, so that the driving safety and comfort are improved.
本公开提供一种车辆防滑控制方法、系统、车辆及存储介质,涉及车辆技术领域。该方法包括:获取车辆中电机的实际转速;确定当前路面下电机的目标转速;根据当前时刻的转速偏差值,生成当前时刻的扭矩调节信号;在当前时刻的扭矩调节信号的频率大于或等于安全频率的情况下,将下一时刻的转速偏差值输入陷波滤波器,得到下一时刻修正后的转速偏差值;根据下一时刻修正后的转速偏差值,生成下一时刻的扭矩调节信号,以便在安全频率下,调节电机的实际转速,从而对车辆进行防滑控制。本公开实施例提供的方案,在对车辆进行防滑控制的同时,能够自适应的消除扭矩调节信号中的波动,从而提升驾驶安全性和舒适性。
