基于ARM和Qt/E的车载HMI终端的设计

摘要

On-board HMI is the key component between driver and his vehicle enabling human to control over the machine. A new type of on-board HMI terminal is designed combining touch control and digital display based on ARM processor and transplanted Qt/E. The experimental results from using a Polo car CAN test- bed shows the basic equipments can be touch-controlled and the vehicle running state information can be displayed real-timely. The terminal can meet the system requirements for HMI.%车载HMI是人与车辆之间的关键设备,使人能够对车辆的运行实现控制；设计了一种触摸控制与数字显示合理结合的车载HMI终端,采用ARM作为处理器,通过移植Qt/E对系统加以实现;该终端通过在Polo车CAN总线试验台测试,实现了对基本设备的触摸控制和车辆状态信息的实时显示,表明所设计的终端能够满足车载HMI的基本要求.
