The invention discloses a vehicle and a driving anti-skid torque distribution method and device thereof. The method comprises the steps that the activation state of a front axle TCS function and the activation state of a rear axle TCS function of the vehicle are obtained; determining an inter-axle torque distribution coefficient according to the activation state of the front axle TCS function and the activation state of the rear axle TCS function; determining a front axle distribution demand torque and a rear axle distribution demand torque based on the inter-axle torque distribution coefficient; and determining a front axle target torque and a rear axle target torque according to the activation state of the front axle TCS function, the activation state of the rear axle TCS function, the front axle distribution torque or the front axle request torque, and the rear axle distribution torque or the rear axle request torque. According to the distribution method, the total driving torque is not reduced to the maximum extent in the activation process of the TCS driving anti-skid function, the total driving torque is close to the torque required by a driver as much as possible, and power loss is reduced.

    本发明公开了一种车辆及其驱动防滑扭矩分配方法和分配装置,所述方法包括:获取车辆的前轴TCS功能的激活状态和后轴TCS功能的激活状态;根据前轴TCS功能的激活状态和后轴TCS功能的激活状态确定轴间扭矩分配系数;基于轴间扭矩分配系数确定前轴分配需求扭矩和后轴分配需求扭矩;根据前轴TCS功能的激活状态、后轴TCS功能的激活状态、前轴分配扭矩或前轴请求扭、后轴分配扭矩或后轴请求扭矩确定前轴目标扭矩和后轴目标扭矩。本发明的分配方法,能够实现TCS驱动防滑功能激活过程中总驱动扭矩最大程度的不降低,使总驱动扭矩尽量与驾驶员需求扭矩接近,减少动力损失。
