Description

Technical field [0001] The present invention relates to the field of hybrid electric vehicle control, in particular to a hybrid electric vehicle torque distribution system and method based on parallel control. Background technique [0002] Hybrid electric vehicles (HEV) combine the advantages of traditional fuel vehicles and pure electric vehicles, and at the same time have the characteristics of low emissions and low energy consumption, and become the most promising vehicles today. Hybrid electric vehicles include at least two vehicle-mounted power sources designed to increase the flexibility of system control. Through the coordinated control of the power source and other components, different working modes can be formed to adapt to different driving conditions. Therefore, vehicle control strategy is the key technology that determines vehicle energy consumption and emissions. Establish an advanced and reasonable torque distribution control strategy, and use the auxiliary torque...
