概述

As automotive technology continues to evolve, vehicles such as cars, commercials and EVs have more and more features which are controlled electronically. It is also typical to see some features and functions available on only some models of the vehicle, or even available as options after purchase. Traditional methods of control such as mechanical dials, switches and LEDs are no longer flexible enough and could lead to cluttered control panels. The colour touch display is a good way for designers to embrace this trend as controls can be laid out in a user-friendly manner, either on dedicated displays or as multiple pages on the same display. Systems such as Climate Control, Tyre Pressure Monitoring, and Seat position can be controlled as well as other features such as lighting and many others. The EVE devices are an ideal solution, especially the latest generation BT817A which has AEC-Q100 qualification. Other EVE devices can also be used depending on the application if AEC qualification is not needed. Here are just some of the benefits of using touch-enabled displays for Climate Control, Type Pressure Monitor, Seat Position and other multi-function displays:

  • Allow multiple functions to be controlled on a single display by having different pages and menus
  • Use touch to select menus and operate controls, and have context sensitive menus that appear when needed
  • Replace complex mechanical controls with a touchscreen
  • Sound audio tones and alerts to the driver and passengers easily without burdening the MCU
  • Use common hardware platforms between models with features enabled via software
  • Update and enhance features easily via software during servicing etc.

主要特征​

The following key features of EVE make it ideal for automotive multifunction display applications:​

  • 符合 AEC 标准的 BT817A 为汽车应用提供更宽的温度范围
  • Wide range of screen shapes/sizes supported e.g.
    • 3.5″ or 5” panels for panels located around the cabin
    • 10.1” or 7″ for the main multifunction console panel
  • Capacitive touch interface with up to 5 simultaneous touches
  • Touch tagging and tracking make buttons, keypads and rotary controls simpler to implement
  • EVE 连接的闪存芯片支持 (BT81x) 允许独立于主机 MCU 进行图像存储
  • 自定义字体允许多语言支持和符号/单位
  • 音频输出和内置声音范围，用于警告和指示声音等
  • PWM调光输出可动态调节屏幕背光亮度
