The invention discloses an engine overspeed protection control method, a vehicle-mounted controller and a vehicle. The engine overspeed protection control method comprises the steps that the current vehicle speed is obtained; based on the current vehicle speed, a target gear matched with the current vehicle speed is determined; and outputting display information, wherein the display information is used for prompting a driver to switch to the target gear. According to the technical scheme, the target gear matched with the current vehicle speed can be determined on the basis of the current vehicle speed under the working condition that the vehicle needs to downshift, the display information for prompting a driver to switch to the target gear is output, the driver can be reminded to conduct gear shifting operation in time when the vehicle runs at a high speed, and the driving safety is improved. And the target gear needing to be reduced currently is displayed, and overspeed operation of the engine is avoided.

    本申请技术公开了一种发动机超速保护控制方法、车载控制器以及车辆中,发动机超速保护控制方法包括:获取当前车速;基于当前车速,确定当前车速所适配的目标挡位;输出显示信息,显示信息用于提示驾驶人员切换到目标挡位。本申请技术方案能够在车辆需要降挡的工况下,基于当前车速,确定与当前车速所适配的目标挡位,并输出提示驾驶人员切换到目标挡位的显示信息,在车辆高速行驶时能够及时提醒驾驶人员进行换挡操作,并展示当前所需降低到的目标挡位,避免发动机超速运行。
