Beschreibung
Zusammenfassung:	The invention discloses a virtual wheel speed measuring method, a virtual wheel speed sensor and a vehicle. The method comprises the following steps: establishing a vehicle wheel speed model based on a steering angle; the longitudinal speed, the lateral acceleration and the steering wheel angle of the vehicle are obtained, and the virtual wheel speed is obtained through calculation by means of the established vehicle wheel speed model based on the steering angle; wherein if the rear wheel speed sensor is reserved, the wheel speed measured by the rear wheel speed sensor serves as the longitudinal speed of the vehicle, and the virtual wheel speed of the front wheel is obtained through calculation; if the front wheel speed sensor is reserved, the longitudinal speed of the vehicle is obtained in combination with the obtained steering wheel rotation angle and the front wheel speed, and the virtual wheel speed of the rear wheels is obtained through calculation. According to the invention, the wheel speed can be mea
