| With the environmental and energy issues caused by the widespread use of automobiles,new energy vehicles are generally accepted as a countermeasure.Under the premise that the key technology of electric vehicles fails to break through,the hybrid vehicle as a transitional stage will inevitably become the mainstream trend of automobile development for a long period of time in the future.This paper studies the vehicle impact problem and energy management problems introduced by the engine.The specific research work of this paper is as follows:(1)Through the mastery of the structure and principle of the fully automatic integrated hybrid powertrain,the selection of key components of the powertrain is completed and modeled at the same time.(2)Complete the hardware design of the solar mainstream passenger car control system.Mainly for the vehicle controller and its control core module,signal processing,power drive,power supply and communication interface and other module chip selection and circuit design.(3)The mode switching conditions are defined according to the type of the vehicle operating mode state.At the same time,aiming at the whole vehicle impact problem introduced by the engine,a clutch control method based on PID+Bang-Bang control is proposed.The proposed control strategy is verified by simulation experiments.The proposed mode switching control strategy can be effectively reduced.When the power is switched,the spindle speed fluctuates,and the impact of the whole vehicle is also significantly improved,which achieves the goal of smooth switching of the power of the mainstream solar passenger cars.Aiming at the energy management problem of solar mainstream passenger cars,a random dynamic programming control method is proposed,which is verified by experimental simulation.Figure 36;Table 6;Reference 58. |
