The invention discloses a control method and device for a vehicle range extender, a vehicle and a storage medium. The method comprises the steps that the pure electric running remaining electric quantity value of a power battery of the vehicle and a target running road section of the vehicle are obtained; determining an expected total demand electric quantity value and an expected total generating capacity value of the vehicle based on the target driving road section; determining an expected total electric quantity difference value based on the pure electric driving residual electric quantity value, the expected total electric quantity generation value and the expected total demand electric quantity; if the expected total electric quantity difference value is larger than a first preset electric quantity value, a target power generation level is determined based on the expected total electric quantity difference value and a preset mapping relation, the target power generation level is one of a plurality of candidate power generation levels, and power generation powers corresponding to the candidate power generation levels are different; the preset mapping relation is used for indicating the mapping relation between the expected total electric quantity difference value and the candidate power generation level; and controlling a range extender of the vehicle to generate power based on the target power generation level. By applying the technical scheme, the NVH performance of the vehicle can be taken into account while the requirement for power guarantee of the vehicle can be met.

    本申请公开了一种车辆增程器的控制方法、装置、车辆及存储介质,该方法包括:获取车辆的动力电池的纯电行驶剩余电量值和车辆的目标行驶路段;基于目标行驶路段确定车辆的预期总需求电量值和预期总发电量值;基于纯电行驶剩余电量值、预期总发电量值与预期总需求电量确定预期总电量差值;若预期总电量差值大于第一预设电量值,则基于预期总电量差值与预设映射关系确定目标发电等级,目标发电等级为多个候选发电等级中的一个,各候选发电等级对应的发电功率均不同,预设映射关系用于指示预期总电量差值与候选发电等级的映射关系;基于目标发电等级控制车辆的增程器进行发电。应用本申请的技术方案,能够在满足车辆保电的需求的同时,还兼顾车辆的NVH性能。
