【摘要】：隨著我國山區(qū)高速公路通車?yán)锍痰牟粩嘣鲩L,山區(qū)高速公路的安全問題也日益顯現(xiàn)。本文從山區(qū)高速公路駕駛員車速控制特點角度出發(fā),建立了一個簡單而又適用的駕駛員速度控制模型來描述駕駛員在山區(qū)高速公路中的速度控制特性,該研究成果對山區(qū)高速公路在設(shè)計與安全評價方面具有重要的參考價值。本研究分析了不同道路條件下真實駕駛員的速度控制行為及影響因素,采用相關(guān)理論和方法建立了基于模糊控制的駕駛員速度控制模型;研究了Carsim軟件中的三維道路建模理論、駕駛員方向控制模型和車輛動力學(xué)模型,將本文中所建立的駕駛員速度閉環(huán)控制模型與Carsim中基于二階最優(yōu)預(yù)瞄橫向加速度的駕駛員方向控制模型相結(jié)合構(gòu)成了綜合控制駕駛員模型,并將該駕駛員模型與Carsim中的車輛動力學(xué)模型和三維道路模型相結(jié)合搭建了人-車-路閉環(huán)仿真實驗平臺;在西漢高速秦嶺段進行了道路試驗數(shù)據(jù)采集,采集了熟練駕駛員行駛過程中車輛的行駛狀態(tài)信息,并對試驗數(shù)據(jù)進行了相關(guān)處理,使用湊試法對駕駛員模型進行了參數(shù)標(biāo)定,將參數(shù)標(biāo)定下的駕駛員模型與真實熟練駕駛員在相同道路線形條件下的行駛速度歷程曲線進行對比,上行路段中,仿真實驗與實車試驗行駛速度相對誤差為8%;下行路段中,仿真實驗與實車試驗行駛速度相對誤差為14%,試驗結(jié)果表明該駕駛員速度控制模型具有良好的準(zhǔn)確性和適用性。
[Abstract]:With the increasing mileage of mountain highway, the safety problem of mountain highway is becoming more and more obvious. A simple and applicable driver's speed control model is established to describe the driver's speed control characteristics in mountainous highway. The research results have important reference value for the design and safety evaluation of mountain expressway. This study analyzes the speed control behavior and influencing factors of real drivers under different road conditions. The driver speed control model based on fuzzy control is established by using relevant theories and methods, and the 3D road modeling theory, driver direction control model and vehicle dynamics model in Carsim software are studied. This paper combines the driver speed closed-loop control model established in this paper with the driver direction control model based on the second-order optimal preview lateral acceleration in Carsim. The driver model is combined with the vehicle dynamics model in Carsim and the three-dimensional road model to build the human-vehicle-road closed-loop simulation platform, and the road test data are collected in the Qinling section of the Western Han high-speed. The driving state information of the vehicle during the driving process of the skilled driver was collected, and the test data were processed, and the driver model was calibrated with the method of cobbler test. This paper compares the driving speed history curve of the real skilled driver with that of the real skilled driver under the same road alignment condition. The relative error between the simulation experiment and the real vehicle test is 8 in the uplink section, and the relative error is 8 in the downlink section, and in the downlink, the relative error between the simulation experiment and the real vehicle test is 8. The relative error of the driving speed between the simulation experiment and the real vehicle test is 14. The test results show that the driver speed control model has good accuracy and applicability.
