The invention discloses an automobile creeping working condition control method and system. According to the automobile creeping working condition control method, creeping judgment parameters are obtained; whether an automobile enters a creeping working condition or not is judged according to the creeping judgment parameters; if the automobile enters the creeping working condition, a creeping driving mode of the automobile is activated, and the automobile is enabled to drive according to an accelerator pedal characteristic curve under the creeping driving mode; in the accelerator pedal characteristic curve under the wrig creeping driving mode, the opening degree of an accelerator pedal is 0, the rotating speed of an engine of the automobile ranges from 650 rmp to 2000 rpm and is divided into at least ten subdivision rotating speed points corresponding to different torque values; and therefore, the creeping starting response and creeping stable automobile speed of the automobile can beimproved, the creeping performance of the automobile is optimized, and the drivability of the whole automobile is improved.

    本发明公开了一种汽车蠕动工况的控制方法及系统,其中,在汽车蠕动工况的控制方法中,首先获取蠕动判定参数,根据蠕动判定参数判断汽车是否进入蠕动工况;若汽车进入蠕动工况,激活汽车的蠕动行驶模式,并使汽车按照蠕动行驶模式下的油门踏板特性曲线行驶;其中蠕动行驶模式下的油门踏板特性曲线中,油门踏板的开度为0的状态下,汽车的发动机转速在650rmp~2000rpm之间,并且被划分为至少10个对应不同扭矩值的细分转速点,可提高车辆蠕动起步响应及蠕动稳定车速的大小,优化汽车蠕动性能,改善整车驾驶性能。
