This paper presents a method to implement the opening of vehicle network data. This method uses STM 32 as the master chip, MCP2551 as the CAN Transceiver and RTL8019AS as the Ethernet Controller. In this method, slave nodes communicate with the master node by CAN bus while the master node communicates with the host computer by the Ethernet. A temperature signal acquisition system is designed as one node of the Ethernet in this paper. The host computer can collect temperature data of this node via Ethernet. The method presented in this paper lays the foundation for realization of remote fault diagnosis for the Vehicle Body System. It also provides a new way for car manufacturers to collect data of the vehicle system, which is very important in improving the performance of products.
