纯电动汽车CAN总线通信液晶显示系统

LCD Information System for Electrical Vehicle Based on CAN Bus

针对电动汽车的发展需要,设计了一种基于DSP和CAN总线的纯电动汽车通信液晶显示系统。首先设计了电动车各CAN总线节点,完成了与电池管理单元和电机驱动单元的通讯,通过串口TFT液晶显示屏的信息提示,实现了对电动汽车各种运行工况的监测和控制。

According to the development needs of Electric Vehicles （EV）, a LCD information system for EV based on DSP and CAN bus is designed in this paper. The CAN bus nodes are designed, and the communication with the battery management unit and the motor drive unit is completed. With the LCD information suggests, the EV running condition can be monitored and controlled.
