The invention relates to an HCU-oriented hybrid electric vehicle scene adaptive mode decision-making method, which comprises the following steps of: obtaining a pre-constructed mapping mode decision-making result, constructing a mode decision-making strategy with parameter function control on the basis of the pre-constructed mapping mode decision-making result, acquiring data to construct a training set, and optimizing each undetermined parameter of the mode decision-making strategy; the method comprises the following steps: acquiring driving data of a tested hybrid electric vehicle in real time, obtaining a mode decision result by adopting a mode decision strategy, establishing a typical working condition capable of reflecting current driving scene characteristics according to a working condition construction algorithm, and evaluating the difference between the typical working condition of the current driving scene characteristics and the working condition characteristics obtained by the mode decision strategy. Therefore, online parameter updating of the mode decision strategy is carried out. Compared with the prior art, the method has the advantages that the reproduction degree of a mode decision result of an advanced algorithm in HCU application is improved; in the face of new scenes, mode decisions can be adaptively and flexibly adjusted, and parameter updating is efficient and convenient.
