Design and Implementation of an Embedded Intelligent Instrument for Pure Electric Vehicles

摘要

In order to deal with the dissatisfaction of traditional automobile instruments applied in pure electric vehicles, an automobile intelligent instrument is designed to meet new requirements of the pure electric vehicles by combining the embedded development board with the embedded configuration software MCGS. In this instrument, the hardware development platform is developed to communicate with the main controller of vehicles by extending CAN bus interfaces on the embedded development board, the main control chip of which is S3C2440. Moreover, the embedded configuration software MCGS is adopted to achieve the software design of the instrument system. Compared with traditional automobile instruments, the intelligent instrument is of high reliability, high precision and diversifications in display interfaces and can be installed in pure electric vehicles as a universal instrument.
