Abstract

The invention discloses a dynamic torque cooperative control method of a planetary series-parallel hybrid power system. The dynamic torque cooperative control method comprises two development parts ofan offline calculation method based on model prediction and an online cooperative control method. Firstly, a dynamic model of the planetary series-parallel hybrid power system is built, and an outputtorque observation model and a shock extent observation model of the planetary series-parallel hybrid power system are deduced based on the dynamic model of system; then, the output torque observation model and the shock extent observation model of the system are discretized, and thus a prediction model of the corresponding observed quantity is obtained; offline dynamic control models of a speed-regulating motor and a torque-regulating motor are deduced based on the prediction model; and offline simulating calculation is carried out, control rules of the two motors in the mode switching process are extracted based on the offline calculation result, the online torque cooperating method is obtained, and the online torque is cooperatively controlled.

Description

technical field [0001] The invention relates to a dynamic torque coordination control method of a planetary hybrid power system, which belongs to the control field of hybrid electric vehicles. Background technique [0002] Faced with the current situation of energy shortage and increasingly serious environmental pollution, as an important way to save energy and reduce emissions, the hybridization of automobiles has attracted more and more attention. Among various hybrid system configurations, the planetary hybrid system has two motors and a set of planetary gear coupling mechanism, which can realize the decoupling of the engine speed by using the speed regulating motor, and realize the torque decoupling of the engine by using the torque regulating motor. Coupling, that is, realizes double decoupling of the speed and torque of the engine, which is easy to realize the optimal control of the engine, and has the most prominent energy-saving potential. However, during the mode s...
