The invention provides an optimized control rule extraction method for a planetary hybrid power system and belongs to the technical field of hybrid vehicle control. The optimized control rule extraction method comprises the steps of the extraction of mode switching rules of a battery-only mode and a hybrid mode and the determination of working state assignment rules for each power source under thehybrid mode. The optimized control rule extraction method reduces the operation cost and improve the real-time performance of a control strategy by applying optimization results to the online controlstrategy in the form of control rules. In addition, the optimized control rule extraction method does not rely on the experience of engineering personnel, thereby eliminating a large amount of calibration time and efforts by virtue of automated implementation and providing a basis for automatic optimization and calibration.
Description
technical field [0001] The invention relates to a method for extracting optimal control rules of a planetary hybrid power system, which belongs to the control field of hybrid power vehicles. Background technique [0002] Facing the current situation of energy shortage and increasingly serious environmental pollution, considering the mileage anxiety of pure electric vehicles, hybrid vehicles are still an important way for vehicles to save energy and reduce emissions in the short to medium term. In various hybrid system configurations, the planetary hybrid system has two motors and a set of planetary gear coupling mechanism, which can use the speed regulating motor to realize the decoupling of the engine speed, and use the torque regulating motor to realize the torque decoupling of the engine. That is to say, the double decoupling of engine speed and torque is realized, and it is easy to realize the optimal control of the engine, and has the most prominent energy-saving potent...
