The invention relates to a wheel inflation and deflation control method, and belongs to the technical field of automobile control, and the method comprises the steps that the slip rate of each wheel of a vehicle and the yaw velocity of the vehicle are obtained; a slip rate difference value of each wheel is obtained based on the slip rate of each wheel, and a yaw velocity difference value is obtained based on the yaw velocity; the deviation degree of the slip rate and the deviation degree of the yaw velocity of each wheel are obtained based on the slip rate difference value and the yaw velocity difference value of each wheel; obtaining a target tire pressure of each wheel based on the deviation degree of the slip rate of each wheel, the deviation degree of the yaw velocity, a preset working low tire pressure and a preset working high tire pressure; and determining to deflate or inflate each wheel based on the target tire pressure and the actual tire pressure of each wheel. The target tire pressure of each wheel is finally obtained based on the slip rate of each wheel and the yaw velocity of the vehicle, and the actual tire pressure of the wheel is adjusted according to the target tire pressure, so that the dynamic property of the wheel is improved.

    本发明涉及一种车轮充放气的控制方法,属于汽车控制技术领域,其中,该方法包括:获取车辆每个车轮的滑转率和车辆的横摆角速度;基于每个车轮的滑转率得到每个车轮的滑转率差值,基于横摆角速度得到横摆角速度差值;基于每个车轮的滑转率差值和横摆角速度差值得到每个车轮滑转率的偏离度和横摆角速度的偏离度;基于每个车轮的滑转率的偏离度、横摆角速度的偏离度、预设的工作低胎压以及预设的工作高胎压得到每个车轮的目标胎压;基于每个车轮的目标胎压和实际胎压确定对每个车轮进行放气或者充气。本发明基于每个车轮的滑转率以及车辆的横摆角速度最终得到每个车轮的目标胎压,根据目标胎压调整车轮的实际胎压,从而提高车轮的动力性。
