In order to read and write the motor controller parameters, download the motor controller program and make the upper computer interface display the running state of the new energy vehicle drive system. This paper designs a serial communication host computer software using Modbus communication protocol and Ymodem communication protocol. The CAN bus interface is provided by the motor controller. The PC is connected to the CAN bus interface of the controller through USB to realize the communication hardware connection between the upper computer and the lower computer. MFC development framework and C + + programming language are used to complete the development of the upper computer software in Visual Studio 2015. Through the analysis of CAN Bus Analyzer and motor test bench, it shows that the upper computer software runs stably and can correctly read the motor controller parameters and send data to it. The design meets the expected requirements.
