Research On The Identifying Method And Application Of Driving Intention

Along with the progress and development of the world, various of high and new technologies are bring forth the new through the old in unceasing weeding. Along with the emergence of a variety of high-tech products, our daily life has become more convenient. This performance is very obvious on automotive product. The automobile develop from the most primitive "does not have horse’s horse-drawn vehicle to the present high-tech product which collect each kind of intelligence technology in a body. Using the vehicle has brought very big convenience for people who use it. Driving vehicle is more simpler, the labor intensity is more lower, riding comfortableness is more higher, the automobile’s power and efficiency is more effective.The computerization and intellectualization of automotive product are developing unceasingly, many of the operations and implementations of functions in vehicles do not require the driver’s participation. Although this reduced the driver’s labor intensity, because of the incorrect read of driver’s intentions, the realization of some functions don’t satisfy the driver. Therefore, many scholars and engineers began to study how to properly identify drivers’intentions, which enables the car of the future to be able to truly intelligent humanoid type operation and driver assistance.With the application of the electronic products on automobile, the emergence of automatic transmission has brought very big promoter action to the promotion of automobile Because of the automatic transmission vehicles can shift simpler and operate more convenient, it can reduce the different driving skill disparity, therefore, it become the more and more person’s first choice. Because of this, the research to automatic transmission vehicles are growing, what’s more, the main research is about the automatic shift schedule. The development of the research about the automatic transmission shift schedule is from the initial single parameter, two parameter, three-parameter shift schedule to the present fuzzy control and neural network control which considered the vehicle running and the driver’s intentions In recent years, some scholars apply the driver’s driving intention distinguish method in the automatic transmission shifting schedule which carries on the identification to some state of roads or the operating mode driving intention. But all these researches are quite single, and the driving intention which obtained is not the real-time monitor result.The problem that exists in automatic transmission shift schedule is that it cannot recognize the driving intention which cased by the controlling action in the automobile driving environment and running status. This article mainly researches about this problem. Therefore, this article mainly conducts the research and the analysis from the following several aspects:First of all, in the foundation of reading a lot of domestic and foreign articles related to how to formulate the automatic transmission shift schedule and how to identify the drivers’driving intention, summarizes and outlines the significance that this article has and the research situation about the identification of driving intention in domestic and foreign countries.Secondly, based on the main content of the identification of driver’s manipulation intention, this article analysis the common driving action type the driver did in the course of driving a vehicle. And obtain the operation data and vehicle condition data correlated through solid vehicle experiment.Then, in order to establish the quantification mathematical model of driver’s operating intention, this article analyzes the flow of how to identify the driver’s driving intention, then based on this to organize the quantification mathematical model of driver’s driving intention under different traveling road conditions using the method of weighting matrix according to the field measurement data.Finally, to operates the intention quantification mathematical model to apply in the pilot who under different state of roads condition this article establishes the revision of automatic transmission shifting strategy, And use Matlab/Simulink software to build simulation models for vehicle power transmission systems, Through the simulation contrast analysis, confirms the pilot who establishes to operate the intention quantification mathematical model and to shift gears automatically the accuracy, the rationality which the strategy revises.
