The invention relates to the field of hybrid electric vehicles, and discloses a hybrid electric vehicle regenerative braking control method optimized by a particle swarm optimization algorithm, which mainly comprises three parts of front and rear wheel braking force distribution, fuzzy controller design and fuzzy rule optimization by the particle swarm optimization algorithm. Firstly, front and rear wheel braking force distribution is achieved through a front and rear wheel braking force distribution curve; then distribution of front wheel mechanical braking force and regenerative braking force is achieved through a fuzzy controller; and finally, the braking effect and braking energy recovery serve as optimization objective functions, the fuzzy rule is optimized through the particle swarm optimization, and the optimized fuzzy rule is applied to regenerative braking control of the hybrid electric vehicle. According to the method, the fuzzy rule design difficulty is reduced, the energy recovered by braking is improved under the condition that the braking effect is met, and energy conservation and emission reduction of the hybrid electric vehicle are facilitated.
