The invention provides traction control for an all-wheel drive vehicle. A method of controlling torque in an all-wheel drive vehicle limits the duration of traction loss. During a wheel slip event, the controller reduces the commanded torque from the driver demand level. The controller calculates a normalized wheel speed for each wheel based on the measured yaw rate, the measured wheel speed, and the calculated wheel diameter. The controller determines an end of the wheel slip event by comparing the normalized speeds of each wheel with each other.
本公开提供了“用于全轮驱动车辆的牵引力控制”。一种控制全轮驱动车辆中的扭矩的方法限制牵引力损失的持续时间。在车轮滑移事件期间,控制器从驾驶员需求水平减小命令的扭矩。控制器基于测量的横摆率、测量的车轮速度和计算的车轮直径来计算每个车轮的归一化车轮速度。控制器通过将每个车轮的归一化速度彼此进行比较来确定车轮滑移事件的结束。
