The invention provides a creeping starting smoothness control method and system. The method comprises the steps that when a whole vehicle is in a creeping starting stage, a vehicle control unit (VCU) receives an ACC activation signal, a torque activation signal and a current cruise acceleration torque sent by an ESC controller; and the received current cruise acceleration torque is compared with the creeping starting control torque of the vehicle, and if the current cruise acceleration torque is close to the creeping starting control torque, whole vehicle torque control right is transferred, and the whole vehicle is controlled to start with the current cruise acceleration torque as the driving torque of the whole vehicle. Only when the ACC cruise acceleration torque is close to the creeping starting control torque of the VCU, transfer of the whole vehicle torque control right can be executed, and therefore, the smoothness of activating the ACC at the moment of creeping starting of the whole vehicle can be guaranteed.
本发明提供一种蠕行起步平顺性控制方法及控制系统,方法包括:当整车处于蠕行起步阶段时,整车控制器VCU接收ESC控制器发送的ACC激活信号、扭矩激活信号和当前巡航加速扭矩;将接收的当前巡航加速扭矩与自身的蠕行起步控制扭矩进行比较,若当前巡航加速扭矩与蠕行起步控制扭矩接近,对整车扭矩控制权进行移交,使得整车以当前巡航加速扭矩作为整车驱动扭矩控制车辆起步。本发明中只有当ACC巡航加速扭矩与VCU的蠕行起步控制扭矩接近时,才会执行整车扭矩控制权的移交,这样能够保证整车蠕行起步瞬间激活ACC的平顺性。
