The invention belongs to the technical field of new energy passenger cars, and provides a new energy intelligent network connection passenger car creeping control system and method, and the system comprises a whole car controller, a motor controller and a driving system; the controller is used for reading the condition judgment signal and the motor rotating speed signal, judging whether the whole vehicle enters a wriggling mode or not according to the condition judgment signal, entering the wriggling mode if the judgment signal meets all judgment conditions, calculating the current vehicle speed according to the motor rotating speed signal, and outputting the current vehicle speed. The expected output torque of the driving motor is adjusted based on the difference value between the current vehicle speed and the target vehicle speed, and the final required torque value is sent to a motor controller; the motor controller is used for sending a torque request to the driving system, and the whole vehicle wriggles under the required torque value.
本发明属于新能源客车技术领域,提供了一种新能源智能网联客车蠕动控制系统及控制方法,包括:整车控制器、电机控制器以及驱动系统;所述控制器用于读取条件判断信号和电机转速信号,根据条件判断信号判断整车是否进入蠕动模式,若所述判断信号满足所有判断条件,则进入蠕动模式,根据电机转速信号计算当前车速,基于当前车速和目标车速的差值调整驱动电机期望输出扭矩,并将最终的需求扭矩值发送给电机控制器;所述电机控制器用于向驱动系统发送扭矩请求,整车在该需求扭矩值下进行蠕动。
