The invention belongs to the technical field of electric vehicle control, and discloses a novel electric vehicle capable of reducing the steering radius, a control system and a control method. The novel electric vehicle control method capable of reducing the steering radius comprises the steps that the steering angle of a steering wheel is detected through a steering wheel rotation angle sensor; the rolling speed of the driving wheel is detected through a driving wheel rolling angle sensor; signals of all the sensors are received through the steering control computer, calculated and analyzed,then judgment is made, corresponding rotating speed instructions are sent to the two steering motors and the hub motor, and finally automobile small-radius steering meeting Ackerman steering geometrical characteristics is achieved. The novel electric automobile capable of reducing the steering radius is provided with the two steering motors, the two steering motors independently control the rotating angles of the steering wheels on the same side respectively, the Ackerman steering geometrical relationship can be achieved more easily through accurate control of a computer, and switching of theautomobile between different steering modes is achieved.
本发明属于电动汽车控制技术领域,公开了一种新型可减小转向半径的电动汽车、控制系统及控制方法,新型可减小转向半径的电动汽车控制方法包括:通过转向轮转动角度传感器检测转向轮转向角度的大小;通过驱动轮滚动角度传感器检测驱动轮的滚动速度大小;通过转向控制电脑接收所有传感器的信号并进行计算和分析,然后做出判断并对两个转向电机和轮毂电机发出相应的转速指令,最终实现符合阿克曼转向几何特性的汽车小半径转向。本发明提供的新型可减小转向半径的电动汽车,有两个转向电机,它们分别单独控制着同侧的转向轮的转动角度,通过电脑的精准控制,能够更容易达到阿克曼转向几何关系,实现汽车在不同转向模式之间的切换。
