摘　　要：设计了一款基于CAN总线的汽车仪表。仪表系统控制器选用了NEC公司的μPD78F0822单片机,CAN通信应用层完全遵循SAEJ1939协议,给出了系统软硬件设计方案,并利用CANoe模拟车况发送节点进行了系统测试。试验结果表明,该系统设计方案具有较高的可靠性,基本上能够满足现代汽车对仪表系统指示精度及稳定性的要求。A car instrument based on CAN bus is introduced. System controller chooses theμPD78F0822 microcontroller of the NEC corporation, CAN bus communication protocol completely conforms to the SAE J1939, providing the system hardware and software design, and finally, using the CANoe as a send node simulating the car information, the system was tested. The experiment results show that this design has high reliability, basically can meet the stability and precision request of the modern car instrument system.
