The invention discloses a rule control parameter optimization method based on a unified model of a hybrid electric vehicle, and belongs to the technical field of hybrid electric vehicle control. The method aims at solving the problems that in the existing hybrid electric vehicle development process, the reusability of a whole vehicle model is poor, and optimization of control parameters is difficult. The method comprises the following steps: constructing a hybrid electric vehicle model; and determining rule control parameters. The method comprises the following steps: constructing a hybrid electric vehicle model; determining rule control parameters, and sorting and layering the rule control parameter populations through a rapid dominating sorting algorithm; and judging whether the populations at the moment meet a termination condition or not through a target function, if so, ending the optimization calculation, and if not, optimizing the populations through an NSPSOFS algorithm. According to the method, the control parameter optimization precision in a hybrid electric vehicle development process is improved.
