The invention provides an automobile driving controller and a control method thereof.The controller comprises two independently-distributed control units and a driving unit electrically connected with the control units, the control units and a vehicle control unit VCU conduct information interaction through CAN communication, the driving unit is connected with a driving motor, and the driving motor is electrically connected with the control units. The control unit and the driving unit are connected with a power supply unit; the control unit sends a PWM signal to the driving unit according to a collected driving motor signal and an operation instruction issued by the vehicle control unit VCU, and the driving unit converts the PWM signal into a driving level signal to control the driving motor to act. On the premise of ensuring safe driving of the automobile, the application of the automobile in more specific scenes can be met, for example, the VCU receives the angle value of the steering system and the driving speed of the automobile, issues a steering instruction to the four motor controllers, issues 90-degree steering instructions to the front, rear, left and right motors respectively, and automatically enters a side parking mode; and the driving experience of the user can be effectively improved.
本申请提供了一种汽车驱动控制器及其控制方法,所述控制器包括两独立分布的控制单元、以及与控制单元保持电连接的驱动单元,控制单元与整车控制器VCU通过CAN通信进行信息交互,驱动单元连接驱动电机,控制单元与驱动单元均连接有供电单元;控制单元根据采集到的驱动电机信号和整车控制器VCU下发的运行指令,向驱动单元发送PWM信号,驱动单元将PWM信号转换为驱动电平信号以控制驱动电机动作。本申请能够保证汽车安全行驶前提条件下,满足更多特定场景车辆使用,如VCU接收转向系统角度值与汽车行驶速度,并下发转向指令给四个电机控制器,分别给前后左右四个电机下发90℃转向指令,自动进入侧位泊车模式,可有效提升用户的驾乘体验。
