Problems solved by technology

[0005] In order to solve the problem of non-linearity and strong coupling of hybrid electric buses, it is difficult to control quickly and accurately in real time during operation, the parameters of the controller cannot be adjusted in time according to information such as vehicle mechanical wear, and the system efficiency cannot be guaranteed to be optimal during the entire life cycle. Due to the technical problem of low hourly average load rate and low fuel utilization rate, the present invention proposes a parallel control-based hybrid vehicle torque distribution system and its method

Description

technical field [0001] The invention relates to the control field of hybrid electric vehicles, in particular to a parallel control-based torque distribution system and method for a complete vehicle of hybrid electric vehicles. Background technique [0002] Hybrid electric vehicle (HEV) has become the most promising vehicle today because it combines the advantages of traditional fuel vehicles and pure electric vehicles and has the characteristics of low emission and low energy consumption. The design of a hybrid vehicle including at least two vehicle-mounted power sources increases 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, the vehicle control strategy is the key technology to determine the energy consumption and emissions of the vehicle. Establish an advanced and reasonable torque distribution control strategy, and use ...
