Research And Design: Automobile Instrument Plan Based On CAN Bus And SOPC

With the rapidly economical growth. The automobile popularization and widely using in families, the automobile manufacturing is developing quickly in our country; the automobile electronics has occupied very important position in the field of the automobile manufacturing. Electronic Control Unit (ECU) is the core component in automobile electronics; it acts a part in some aspects such as the engine, bodywork, chassis controlling systems and the communication function. But with the development of GPS, vehicle communication and entertainment. The capability of ECU need more powerful.At present, most of the ECU is designs using single chip with peripheral circuit, it has some defects such as low integration rate, bulky, bad dependability; most of ECU chip depends on import, it is so costliness that has no intellectual property rights. Therefore designs has the proprietary intellectual property rights controller has the vital significance to our country automobile industry and other correlation industry development.This dissertation works originates from GAGC's eleventh Five-Year Plan. This plan is produce the automobile of independent brand with independent intellectual and property right. Then this automobile's body, chassis and electronic all need independent design, innovation and develop.This dissertation according as the design request, uses the newest SOPC technology to propose the design proposal. Designed of automobile instrument based on CAN-bus with the hardware description language of VHDL. This automobile instrument can accomplish the system of vehicles including the security, the travelling parameter, the GPS, the vehicle entertainment and other kinds of information with demonstration and control. Also has function of communication based on CAN-bus. It has some advantages such as easing to use, fast proeessing speed, high integration,good depend ability and the low price ate.
