The invention discloses a range extender maintenance prompting method and device and a vehicle, and the method comprises the steps: calculating an engine oil loss characteristic function of a range extender through a bench test, and obtaining the historical operation power of the range extender within a preset operation duration through a cloud; calculating the current total engine oil loss value of the range extender in combination with the engine oil loss characteristic function and the historical operation power; and comparing the current total engine oil loss value with an engine oil loss threshold value, and judging whether a range extender maintenance prompt needs to be sent out or not. The range extender maintenance prompting method provided by the invention is based on the actual loss of engine oil instead of the experience mileage or the maintenance time period, so that the prompting is more accurate and intelligent.

    本发明公开了一种增程器保养提示方法、装置以及车辆,包括:通过台架试验计算增程器的机油损耗特性函数,通过云端获取在预设运行时长内增程器的历史运行功率;结合机油损耗特性函数和历史运行功率计算增程器的当前总机油损耗值;比较当前总机油损耗值与机油损耗阈值,判断是否需要发出增程器保养提示。本发明提供的增程器保养提示方法基于机油实际的损耗而非基于经验里程或保养的时间周期,从而使得提示更加准确和智能。
