The invention belongs to the technical field of engine control of hybrid electric vehicles, and relates to a control method and device of an extended-range engine, a hybrid electric vehicle and a medium. Acquiring a plurality of control parameters, a plurality of preset performance parameters, a working state parameter and an average performance parameter corresponding to the pulse spectrogram; if the working state parameters meet a preset stable condition and the updating interval time of the pulse spectrogram meets a preset interval condition, judging whether each average performance parameter meets a preset deviation condition or not; if the average performance parameters deviate, updating the control parameters through a trained neural network model based on the control parameters and the average performance parameters until the thermal efficiency meets a preset thermal efficiency condition; based on the updated control parameters and the working state parameters, the engine is controlled to provide power for the generator until the generator stops running; and the cost of calibrating each control parameter when the pulse spectrogram deviates is reduced.
本申请属于混合动力汽车的发动机控制技术领域,涉及一种增程式发动机的控制方法、装置、混合动力车辆及介质,包括:若电池荷电状态小于等于预设荷电百分比,获取脉谱图对应的多个控制参数、多个预设性能参数、工作状态参数及平均性能参数;若工作状态参数满足预设稳定条件且脉谱图的更新间隔时间满足预设间隔条件,判断各平均性能参数是否满足预设偏离条件;若各平均性能参数发生偏离,基于控制参数和平均性能参数,通过训练好的神经网络模型更新各控制参数,直至热效率满足预设热效率条件;基于各更新的控制参数和各工作状态参数,控制发动机为发电机提供动力,直到发电机停止运转;降低了在脉谱图发生偏离时标定各控制参数的各项成本。
