The invention provides a wheel anti-slip control method, a whole vehicle controller and a vehicle, and the method comprises the steps: determining the whole vehicle demand torque, and distributing an initial torque for each driving wheel according to the whole vehicle demand torque; determining the actual slip rate of the driving wheel under the action of the initial torque; determining an additional decision moment based on the actual slip rate and the target slip rate; receiving a vehicle driving mode sent by a user, and selectively determining a target driving torque for driving the wheels based on the vehicle driving mode, the basic torque for driving the wheels or the reference driving torque; the reference driving torque comprises the basic torque and the additional decision torque; the current driving torque of the driving wheel is adjusted to be consistent with the target driving torque, so that the sliding wheel stops sliding; therefore, in different vehicle driving modes, the torque of the driving wheel can be selectively adjusted in real time based on the basic torque or the reference driving torque of the driving wheel, so that the sliding wheel stops sliding, and the safety and the stability of the vehicle are effectively improved.
本发明提供一种车轮防滑转的控制方法、整车控制器及车辆,包括:确定整车需求力矩,根据整车需求力矩为各驱动车轮分配初始力矩;确定驱动车轮在初始力矩作用下的实际滑转率;基于实际滑转率及目标滑转率确定附加决策力矩;接收用户发送的车辆驱动模式,选择性地基于车辆驱动模式、驱动车轮的基础力矩或参考驱动力矩确定驱动车轮的目标驱动力矩;参考驱动力矩包括所述基础力矩及所述附加决策力矩;将驱动车轮的当前驱动力矩调节为与目标驱动力矩一致,使得滑转车轮停止滑转;如此,不同的车辆驱动模式下,可选择性地基于驱动车轮的基础力矩或参考驱动力矩来实时调节驱动车轮的力矩,进而使得滑转车轮停止滑转,有效提高车辆的安全性和稳定性。
