基于驾驶员意图采集的车辆状态控制系统分析

Control System Analysis of the Vehicle State Based on the Driver Condition Recognition

驾驶员操作意图是整车状态变化的基础,对整车运行具有重要影响。以驾驶员操作意图为研究的出发点,对驾驶员执行车辆各种操作时,车辆的状态进行分析,主动包括启动自检工况,档位变化、加速、制动、转向等工况;基于分析结果对各工况的控制流程进行分析和设计;提出了实现车辆基本功能的控制模式,并对控制电路进行设计。在此基础上,应用实车调试,对控制系统进行了测试。结果可知:对车辆进行准确控制的前提是对驾驶员意图进行准确的分析采集,控制流程应简洁明了,尽可能减少控制器的执行周期,缩短控制周期;实车测试表明系统能准确的实现驾驶员的操作意图,实现加速、减速、制动等,表明所设计的控制系统的可靠性与准确性,为此类设计提供参考。

Driver’s operation intention is the basis of vehicle state change,which has an important impact on vehicle operation.Taking the driver’s operation intention as the starting point,the state of the vehicle was analyzed when the driver performs vari-ous operations of the vehicle,including starting self-test condition,gear change,acceleration,and braking,steering and other conditions.Based on the analysis results,the control process of each condition was analyzed and designed.The control mode to re-alize the basic functions of the vehicle was proposed,and the control circuit was analyzed.On this basis,the control system was tested by real vehicle debugging.The results show that:the premise of accurate control of the vehicle is the accurate analysis and collection of the driver’s intention.The control process should be simple and clear,reduce the execution cycle of the controller as far as possible,and shorten the control cycle.The real vehicle test shows that the system can accurately realize the driver’sopera-tion intention,realize the acceleration,deceleration,braking,etc.,indicating the reliability and accuracy of the designed con-trol system which can provide reference for this kind of design.
