The invention discloses a hybrid electric vehicle control method and system based on driving style recognition. The method comprises the steps that driving data to be recognized are collected, the driving data to be recognized are processed to obtain parameters to be recognized, the driving data are collected, characteristic parameters are extracted according to the collected data, and the characteristic parameters comprise the speed, the accelerator pedal opening degree change rate and the brake pedal opening degree change rate; an S4VM driving style recognition model is established based ongenetic algorithm optimization, the parameters to be recognized are input into the model to obtain a driving style recognition result, and optimal control parameters of the vehicle are obtained according to the driving style recognition result; an optimal vehicle control parameter is obtained according to a driver driving style recognition result; and a control strategy is established by taking the minimum energy consumption of the whole vehicle as an optimization target, and the control strategy is adaptively adjusted according to the driving style. Vehicle control parameters are adjusted through driving style recognition, so that an engine works in an efficient area, and the fuel economy of the whole vehicle is greatly improved.
