The present invention provides the estimation of vehicle speed in a all-wheel-drive vehicle. The vehicle includes an electric machine and a controller, and the controller is programmed to responsive to a threshold difference, indicative of wheel slip, between the average wheel speed and the vehicle speed that is based on a difference between the wheel acceleration and the measured vehicle acceleration, to command a speed to the electric machine to reduce the wheel slip.

    本公开提供了“全轮驱动车辆中对车辆速度的估计”。一种车辆包括电机和控制器。所述控制器被编程为响应于平均车轮速度和基于车轮加速度和测量的车辆加速度之间的差的车辆速度之间的指示车轮打滑的阈值差,而向所述电机命令速度以减少所述车轮打滑。
