Abstract

The invention discloses a power distribution method of a mechanical-electric transmission tracked vehicle. According to the power distribution method of the mechanical-electric transmission tracked vehicle, the needed power of a driver is regarded as a discrete random dynamic process, a markov model of the needed power of the driver is built by summarizing driver powers of multiple cyclic operation states, a recursive decision equation is built based on the random dynamic planning concept, and the optimal power distribution method of random conditions is obtained through solution. The power distribution method of the mechanical-electric transmission tracked vehicle overcomes the defect a control strategy based on rules and a control strategy based on instant optimization can not realize the optimal fuel oil economy in the whole course, takes the characteristics of whole-course optimization of dynamic planning solution and the advantages of a markov decision processing random process into account and can realize whole-course optimization, thereby effectively improving the fuel oil economy of the mechanical-electric transmission tracked vehicle.

Description

technical field [0001] The invention belongs to the technical field of electromechanical compound transmission control, and in particular relates to a method for distributing power of a crawler vehicle with electromechanical compound transmission. Background technique [0002] For tracked vehicles with electromechanical compound transmission, the power distribution control strategy directly determines the driving performance of the vehicle, and the formulation of the control strategy is one of the key technologies for tracked vehicles with electromechanical compound transmission. The control strategy should not only achieve the best fuel economy of the vehicle, but also take into account the requirements of engine emissions, power battery life, driving performance, reliability of each component and vehicle cost, etc. The characteristics of each component and the operating conditions of the vehicle enable the engine, motor, power battery pack and transmission system to achiev...
