The invention relates to the technical field of hybrid electric vehicles, and discloses an engine control method and device of a hybrid electric vehicle, the hybrid electric vehicle and a storage medium. State parameters and target demand power of the vehicle are obtained, initial discharge power of a battery and the current starting frequency of an engine in unit time are obtained, and then the engine is started according to the initial discharge power of the battery and the current starting frequency of the engine in unit time; the initial discharge power is corrected based on the current starting times and the state parameters to obtain the actual discharge power, the accuracy of battery discharge capacity calculation is improved, and therefore whether the difference value between the actual discharge power and the target demand power is smaller than the preset power threshold value or not is detected more accurately, and starting of an engine is controlled conveniently; assistance is provided for vehicle driving, vehicle driving is smoother, and the driving experience of a user is improved.
本发明涉及混合动力汽车技术领域,公开了混动车辆的发动机控制方法、装置、混动车辆及存储介质,本发明通过获取车辆的状态参数和目标需求功率,并获取电池的初始放电功率以及发动机在单位时间内的当前启动次数,然后,基于当前启动次数和状态参数对初始放电功率进行修正,得到实际放电功率,提高电池放电能力计算的准确度,从而更准确地检测实际放电功率和目标需求功率之间的差值是否小于预设功率阈值,以便控制发动机启动,为车辆行驶提供助力,使车辆行驶更加顺畅,提高用户驾驶体验。
