Abstract


Energy and environmental issues have become increasingly prominent in today's society, the hybrid technology and the research and development of new energy technologies to the automotive industry, scientific and technological innovation hotspots. Immature technology of new energy vehicles, taking into account the hybrid car has become the first choice of the R \u0026 D of the advantages of the traditional fuel vehicles and electric vehicles. Domestic R \u0026 D as one of the key technologies of the dual-clutch double clutch control system, it is possible to shorten the gap and foreign auto technically, at the same time in the wholly owned independent intellectual property rights on the basis of, we can achieve the dual clutch parts to develop their own hybrid vehicle standards, speed up the development of the automotive industry. The current hybrid program is used mainly in the power structure single clutches program, due to the kinetic energy recovery, do not disengage the engine can not be the biggest the recycled car's kinetic energy, the purpose of this research is to design a hybrid car with a dual-clutch The control system, so that the maximum efficiency of the recovery of kinetic energy, and proposed a hybrid double clutch control strategy and control algorithm of the control system, and verified by experiment. Introduce hybrid dual-clutch control system solutions based on five working modes of the hybrid dual-clutch control system solutions, detailed discussion of the control system control strategy, including the dual-clutch action process control strategy and the implementation of parts (brushless motor) control strategy. Second, the combination of the design method and control strategy proposed in this paper design of hybrid cars with dual-clutch control system hardware circuit and the preparation of the control strategy software program. The executive body parts of the system using a brushless DC motor-driven hydraulic gear, the controller is part of the control core, the counter electromotive force from the motor terminal voltage detect zero with ST7FMC2S6 microcontrollers which according to the dynamic position of the rotor, do the right commutation, and estimate the rotor speed and the number of turns, for closed-loop control loop speed control and position control. Finally, experiments verify that the system has a good response performance, to be completed within 0.3 seconds hybrid car with a dual-clutch control system control strategy, while the hardware circuit is simple, stable and reliable system allows the motor-driven hydraulic device, low manufacturing costs .
