The invention discloses a vehicle gear clearance control method and device and a vehicle. The method comprises the following steps that the triggering frequency of an accelerator pedal of the vehicle within the preset duration is detected; when it is detected that the triggering frequency is larger than the frequent accelerator stepping-on threshold value, the vehicle is controlled to enter the frequent accelerator stepping-on working condition, and the current vehicle speed and the current gear of the vehicle are obtained; and the change rule of the required torque of the vehicle is analyzed, the output pre-tightening torque is determined according to the current vehicle speed, the current gear and the change rule, and the gear clearance of the vehicle is adjusted based on the output pre-tightening torque. Therefore, the problems of whole vehicle shaking, abnormal sound and the like caused by gear clearances when the accelerator is frequently loosened and stepped at present are solved.

    本申请公开了一种车辆的齿轮间隙控制方法、装置及车辆,其中,方法包括以下步骤:检测车辆在预设时长内油门踏板的触发次数;在检测到触发次数大于频繁松踩油门阈值,则控制车辆进入频繁松踩油门工况,获取车辆的当前车速和当前挡位;分析车辆的需求扭矩的变化规律,并根据当前车速、当前挡位和变化规律确定输出预紧扭矩,以基于输出预紧扭矩调整车辆的齿轮间隙。由此,解决了目前频繁松踩油门时齿轮间隙导致的整车抖动、异响等问题。
