摘要
由于现有的仪表板通常是把所有的仪表罗列出来,显得没有重点,本文以当前正处于研发阶段的电动公交车的仪表显示为设计目标,利用液晶显示器代替传统仪表板,采用智能提示和组合变换的方法把最能反映当前工况的仪表状态显示出来。在此基础上设计出来了针对电动公交车的HHEBI-001仪表智能显示系统。
     本文简要的介绍了电动公交车整车控制系统的组成,分析了本仪表系统的整体架构,概括了车载CAN总线网络的工作原理以及仪表显示在整车系统的地位和作用。通过对驾驶工况的分析,统计了HHEBI-001仪表智能显示系统需要采集的信息和需要检测的数据量和传感器类型。信息通过CAN总线网络传输到整车ECU(电子控制单元),在这里信息经过分析再传输到仪表显示系统。依据驾驶经验和当前的工况来判断电动公交车所处状态或车辆的动作,从而通过仪表显示区域对驾驶员当前操作给出简单的提示。
     本设计是在三星公司的s3c2410上搭建硬件平台,连接了8寸液晶显示屏,在其基础上根据需要对linux系统进行了裁减和定制,搭建了嵌入式linux操作系统。使用QT对HHEBI-001仪表智能显示的软件系统进行了详细的设计。在基本仪表界面中设计出了速度表、电机转速表、里程表、能量表、冷却水温度表以及状态灯,并且设计了给驾驶员提示信息的综合显示区域和组合变换区域。为了模拟仪表显示界面的正常工作和汽车在不同工况下仪表显示的作用,最后进行了模拟仿真验证,设计了工况模拟控制台、故障控制台。它们的作用是模拟汽车所处的工况和可能发生的故障。通过在控制台或故障控制台改变选项的状态来模拟工况的改变。经过模拟仿真验证,在指定的工况下仪表显示界面给出鲜明的提示信息,组合变换区域也显示了相应的仪表状态。
It looks no emphasis that all instruments are arranged in the panel like existing product. This paper takes the instrument display of developing electrical bus as designing target. The LCD dispay is emploied to replace traditional panel. Instrument's state which reflect most current driving status is showed on it through intelligent help method and combination transforming method. Furthermore HHEBI-001 intelligent instrument display system is designed.
     This paper briefly introduces the components of electrical bus control system; analyses the intelligent nistrument sysytem structure and generalizes both the operation principle of CAN bus in vehicle and status of instrument display in vehicle control system. By analysing driving status, the paper has sum up the information needed to be collected and parameters needed be checked and sensor's styles in HHEBI-001 intelligent instrument display system. Information is transmitted to ECU(electronic control unit) through CAN bus and passed to instrument display system after being analysed. Currently status and action of electrical bus can be estimated by driving experience and currently condition. Accordingly, a simple assistant driving information is offered to driver in instrument display area.
     This designing hardware flat has been founded on SAMSUNG'S s3c2410 and connected to 8 inch LCD. Linux has been reduced and customized for required, and then the embeded linux is builded up. The designing details of HHEBI-001 intelligent instrument interface has been used of QT. The speedmeter, motor tachometer, odometer, energy meter, cooling water thermometer and status signal lamp have been designed in the basic instrument interface. The integrated display area and combination transforming area for helping driver has been designed as well. The simulation is done in order to simulate the real condition and instrument display function by designing drive status and malfunction console. The drive status can be changed through setting the simulated console. It is validated that the instrument display interface can offer the driver important information in simulation. And corresponding instrument status is represented in combination transforming area.
