The Research On The Vehicle Integrated Display And Control System Based On Embedded Linux

As the speedy development of national economy and the improvement of people's living standard, automobiles will enter thousands of households gradually and become an indispensable daily tool of transportation. Vehicle integrated display and control system is important interaction equipment between the drivers and the automobiles, through which the drives can access the automobiles running status in real-time and operate it better. It supplies reliable safeguard for the automobiles'operation and comfortable environment for traveling. So it is clear that there is important meaning on the research of Vehicle integrated display and control system.Compared with traditional automotive equipments, the vehicle integrated display and control system based on embedded Linux has more real time performance, more intelligent, low power consumption and short development cycle. It is the result of rapid development of computer technology and vehicle technology and it is an important application of computer technology in the automotive technology.A project of vehicle integrated display and control system is given. The project is a low cost, high reliability aptitude, general-purpose solution project of which the core is the embed microprocessors. This paper introduces vehicle integrated display and control system which based on S3C44B0X development board and embedded operating systemμCLinux as embedded hardware and software environment. In order to obtain embedded operating system which suitable for the system, this paper reconfigure and migrate the core of embedded operating systemμCLinux; the ARM processor receive the signal of vehicle speed, rotation speed, water temperature and fuel level which come from sensor of automobile, and the signal is displayed on needle meters or LCD; the system can protect important data in Electrically Erasable Programmable Read-Only Memory (EEPROM) when power off, alarm for over speed and low fuel; the system supplies TFT-LCD module and touch screen module, which can provide interface for new functions.Vehicle integrated display and control system can provide all kinds of information more accurately for drivers in time, it supplies reliable safeguard for the automobiles'operation. In order to the driver can be very intuitive to read the information, the rotation speed, vehicle speed, water temperature and fuel level are displayed on needle meters in this system. And also, it is very easy to upgrade and expand for this system.
