A system and method for estimating a wheel speed of a vehicle are provided. The system includes wheel speed sensor that detects a rotation speed of a wheel of a vehicle and a motor speed sensor that detects a speed of the driving motor. A controller receives a signal of the wheel speed sensor, a signal of the motor speed sensor, and information regarding a gear stage indicating current gear stagestatus of the transmission, and estimates a wheel speed including direction information of wheel rotation.
提供了一种用于估计车辆的车轮速度的系统和方法。该系统包括检测车辆车轮转速的车轮速度传感器和检测驱动发动机速度的发动机速度传感器。控制器接收车轮速度传感器的信号、发动机速度传感器的信号,以及关于指示变速器的当前档位状态的档位的信息,并且估计包括车轮旋转的方向信息的车轮速度。
