Driving Simulator Anti-lock Brake System (ABS) With the increase of the vehicle velocity and augment of the running vehicles density on the road,the requirement which people want about the performance of running vehile for securith is higher and higher. Anti-lock Brake System (ABS) makes an essential contribution to the traffic safety for it ensures optimal stability, steerability and stopping distance during hard braking. ABS has been widely used since the mid of 1980s and has become a standard assembled part in the middle and top grade cars. There are many kinds of control algorithms of ABS,.But,in the present, The utility and effective control logic on the vehicle is logic limit values. As a rual, we carry out the simulation research by the snigle computer, plot the simulation curve applying pure simulated data, and analyse them while researching the Anti-lock Brake System. So it is bad considering the real-time performance and simplex for the judgement and appraisement. The driving simulator of ADSL in JiLin university is the great test equipment device for Simulationn research and exploitation about active safety performance for the vehicle. It is distinguished either from a pure numerical simulator or a pure physical model, or from a simulator for driver training purposes. It can make the driver who is the most difficult for modeling in mathematical and computer forms, participates in the test directly, add to all sorts of accutate dynamics models that are exploited on the driver simulator, so the test done on it is closer to the practical test, in some hand, it can agree about 90% with the true vehicle test. Whats more,it can give the driver the visual, audio, kinematics senses and tactile impression. So ,it has many merits with which the pure simulation test can not compare. Add to the test carried out in the ADSL development driving simulator is safe, either for a professional test driver or for an ordinary driver. The limit operating conditions, such as in the cases of slip, rear wheel slip or losing control at high speed, can be tested safely. So, it is significant to develop the control system that is used to the vehicle, the whole car and assess the vehicle performance applying the driving simulator. In this paper, we researched and exploited the Anti-lock Brake System utilizing the driving simulator of ADSL, based on the analysis of basic control strategy about ABS logic limit values control, established the ABS control model, including hydraulic system model,arrester model and pressure model between the brake pedal and the master cylinder, ect. After interfacing the simulator, through the test on the simulator, the validity of control logic is verified, and by analizing the test result, found the experiences and the rule about adjusting the control parameters of ABS. Specifically, the following research steps have been completed: First, in theory, the basic principle and contruction of ABS are introducd, then, analyzed and compared the merit and the deficiency of each control method, established the design rule of ABS control logic. Second, based on comparing several familiar ABS control logic, analyzed basic control strategy about ABS logic limit values control, established the ABS control model, including hydraulic system model,arrester model and pressure model between the brake pedal and the master cylinder, ect. After interfacing with the simulator, carried out the test on the simulator. Third, identified the road coherence coefficient. Because of the diversity of the road friction conditions that the vehicle encounters while braking, and the difference of the ideal slippage rate is very great on different fricton coefficient road, in order to ensure the work of ABS is normal, and ABS can make good use of the maximal road coherence coefficient that each road can provide, it is necessary to adjust different control logic and strategy according to the different road condition. So, it is essential to identify the road condition. In this dissertation, based on the hydraulic system model, the changing characteristics of hydraulic system are studied, then the relations among hydraulic pressure, the change of wheel angle acceleration and tire-road friction are analyzed. And through identification, found the relation between the change of wheel angle acceleration and tire-road friction. Finally, the limit values of the control logic are analized, and research the influence that each limit brings forth to the control system. After analizing the test result, we draw conclusions about the influence degree that each control parameter brings forth to braking performance, and search after the experiences and rule through which the control parameters are adjusted, so that it provide the instruction while matching the ABS for the new vehicle type in the future. The Anti-lock Brake System model which is built in this dissertation can be applied on the silulator of ADSL, and the adjustment experiences to each control parameter which are drawed in the thesis are greatly helpful for matching ABS to the new vehicle type later.Besides , it will provide the console and experiences while exploiting other control systems used in the vehicle by Driving Simulator in the future. 駕駛模擬器 防抱制動系統(tǒng) (ABS) 隨著汽車行駛速度的提高及道路行車密度的增大 ,人們對汽車行駛安全性能的要求也越來越高 .防抱制動系統(tǒng) (簡稱 ABS)能夠最大限度地保證車輛緊急制動時的 操縱穩(wěn)定性和制動性能 ,從而較大地提高了行車安全性 .自八十年代中 ,后期以來 ,ABS 得到了廣泛而迅速的普及 ,在汽車發(fā)達國家 ,ABS 已經(jīng)成為中 ,高檔轎車的標準裝配部件 .ABS 控制邏輯種類較多 ,但目前車輛上比較實用且有效的控制邏輯為邏輯門限值控制 .在研究制動防抱控制系統(tǒng)時 ,一般的方法是在微機上進行仿真研究 ,應用單純的仿真數(shù)據(jù)繪制成仿真曲線來進行分析 ,實時性差并且判斷 ,評價較單一 . 吉林大學國家汽車動態(tài)模擬試驗室的駕駛模擬器是對汽車主動安全性能等進行仿真研究和開發(fā)的大型實驗裝備 ,它既不同于在計算機上進行的純數(shù)字仿真 ,又不同于臺架或場地試驗等純實物物理模擬 ,它可以讓難以用數(shù)學模擬加以描述的駕駛員直接參與試驗 ,加上模擬器上開發(fā)出的各種精確的動力學模型 ,使得試驗更接近于實車試驗 ,在某些方面可以與實車試驗高達 90%的吻合度 ,并且它可以給駕駛員良好的視覺 ,聽覺 ,觸覺及運動感覺 ,因而它具有許多純仿真試驗無法比擬的優(yōu)勢 ,又由于在駕駛模擬器上可以對多種實車難以完成的極限工況進行試驗 ,因此 ,駕駛模擬器在開發(fā)車用控制系統(tǒng) ,整車產(chǎn)品開發(fā)及性能評價上具有極為重要的作用 . 本文利用實驗室的駕駛模擬器對制動防抱系統(tǒng)進行了研究和開發(fā) ,在分析ABS 邏 輯門限值控制的基本控制策略后 ,建立了具有防抱死制動控制性能的 ABS控制仿真模塊 ,包括 ABS 控制邏輯模塊 ,液壓系統(tǒng)模塊 ,制動器模塊以及制動踏板與制動主缸間的壓力模型等 .在將上面所有子模塊進行包裝成對外僅有輸入輸出接口的獨立模型后 ,與駕駛模擬器進行連接 ,然后在模擬器上進行試驗分析 .通過模擬器試驗 ,驗證了控制邏輯的正確性 ,并對路面附著狀況進行了識別 ,通過辨識找到了車輪角加速度變化與路面附著系數(shù)之間的關系 .通過試驗結果分析 ,找到了 ABS 控制參數(shù)進行調(diào)整的經(jīng)驗和規(guī)律得出了一些對控制參數(shù)進行調(diào)控的經(jīng)驗和規(guī)律 .并且 ,本文 所開發(fā)的制動防抱系統(tǒng)可以應用于駕駛模擬器上 ,從而使駕駛模擬器的動力學模型得到了進一步的完善 . 具體開展了以下幾個方面的研究工作 : 首先 ,從理論上介紹了汽車制動防抱死系統(tǒng)控制的基本原理和結構 ,并分析 ,比較各種控制方法的優(yōu)劣 .在此基礎上確定所開發(fā)系統(tǒng)的基本控制方式
