Research On Fuzzy Control For Vehicle Automatic Garage Parking

Automatic parking technology is one of hot automotive electronic technologies these days, which will greatly reduce the driver's physical and mental strength, as well as reducing the difficulty of parking operation, and traffic accident caused by the reasons such as the driver is not sure about the sense of direction, faulty operations and judges, by the same time, this technology will ultimately have a positive meaning to the unmanned auto vehicles. The content of the research is about the fuzzy control algorithm for automatic vertical parking based on the actual parking lot, and also has give the simulation analysis based on ADAMS/Car vehicle model.This essay comparatively analyses the current different types of automatic parking system's structures as well as the different control methods, based on the actual car parking environmental conditions, it raises a new simple and efficient fuzzy parking control method, which is different from the study of wheeled robot automatic parking of vehicles, sums up the new fuzzy control rules, then uses matlab's fuzzy logic toolbox to build it and gives the simulation results. Meanwhile, it is known that the vehicle's kinematics model plays an important role to the effect of the fuzzy parking control, so this essay analyzes the general vehicle kinematics model then builds an expansion vehicles kinematics model by integrating the structural characteristics of vehicle's steering system, making a better and real effect of the control results. In addition, the essay also researches and analyses the knowledge of the software ADAMS, uses its function of mechanical dynamics simulation, instead of a real vehicle simulation, to establish an ADAMS based vehicle model, and then with the introduce of the Matlab control simulation results to generate the driver file which is used by the ADAMS/Car simulation software. Through analyzing the results, we can find out that this fuzzy control method is effective.The innovations of this essay are as below:developing a new vehicle kinematic model for low-speed parking; researching and analyzing the actual vehicle parking, then designing a compact and efficient fuzzy control algorithm; using ADAMS to simulate the vehicle's parking operation and verifying the effectiveness of the method.
