Simulate Investigation Of The Power Matching For The Parallel Hybrid Electric Vehicle

In this paper, the SVW7183AGi car is taken as the prototype vehicle, the main object of research is the Parallel Hybrid Electric Vehicle (Parallel Hybrid Electric Vehicle is called PHEV), which equipment the planet gears, and the system of power transmission mathematical model for PHEV is established. The Matlab/Simulink is used to simulate the system of power transmission, and its movement is simulated with SolidWorks.The main task and acquire result in this paper includes: Firstly, according to the power matching device type characteristic of PHEV, the PHEV system of power transmission (planet gears) mathematical model is established. Secondly, according to the run mode and mathematic model, the software Matlab is used to establish the Simulink model structure frame fig, which under mix driving modes (startup accelerate and stabilize run) and FUD72 circle drive mode. Thirdly, a further PHEV model on the basis of Matlab/Simulink is used to simulate the speed, power assign and torque output characteristic curve for various situation. Lastly, establishes the system of power transmission model in three-dimensional of PHEV, simulating its movement in various driving mode with SolidWorks.In this paper, the power match method and uses the Matlab/Simulink software obtains the characteristic curve, which by providing the references for studying the optimization of PHEV power match and correspond control, the whole vehicle control strategy and mode, it sets up certain foundation for improving whole vehicle run capability. The Simulation results indicate that this device can achieve the objectives of low oil consumption, low exhaustion and energy saving.
