The panel of automobile is the main instrument of automobile ,through which the driver can get the status of the automobile,and the safety of driving is greatly influenced by it. Recently,with the widely using of computer,micro-electronics and field bus communication technology,automobile electronically technology is developing fast ,and the traditional mechanical and electrical combined instrument could not meet the need any more. Especially with the development of automatic drive and satellite navigation technology ,the panel of automobile is expected to become an integrated information system with multifunction of displaying,controlling,communication and entertainment. The paper is to present and design all onboard panel system in which an ARM controller is used as CPU and Embedded Linux is used as the core of software. With the Embedded Microprocessor as its core,the panel could acquire various information of the vehicle,such as the cell voltage and the vehicle velocity. At the same time,the system can process,display and warn in the abnormal situation. Therefore,the driver could react correctly according to the alarm,which makes the car always run in a safe condition. The appearance of the system is different from the traditional panel of automobile. A LCD screen is used to replace all the traditional display equipment,and all information of the vehicle is displayed on the screen. In order to meet the driving custom of the driver,the speed of vehicle and its engine are displayed on the screen by t
