[0039] The present invention will be described in detail below in conjunction with the drawings:
[0040] Refer to figure 1 To Figure 7, the left and right steering wheel drive shafts of the traditional car are connected by a mechanical differential. Due to the existence of the kingpin offset distance, the longitudinal force on the tire footprint will produce a moment around the kingpin. Generally, on a good road, the left and right steering wheel drive forces generate the moment around the kingpin. The magnitude of the moment around the kingpin is about the same, and the directions are opposite. Offset each other. For electric vehicles with independent steering wheels, since the left and right steering wheels are driven by independent wheel motors, the driving force of each wheel can be individually controlled, and the driving torque generated by the wheel motors is rapid and accurate. The driving force of the wheels can be unequal, then the torque of the driving force to the ax...
