An automotive bus is a communication system used to transfer data and control information in a vehicle's electronic system.<\/p>

It enables different electronic control units (ECUs) to communicate with each other within the vehicle and to coordinate the operation of the various systems, thus realizing functional integration and synergy.<\/p>

In modern automobiles, taking into account the communication performance and cost, the common and widely used automobile bus includes the following three main types:
LIN, CAN and CAN FD.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In electric vehicles and large battery systems, the BMS (Battery Management System) usually communicates with the battery modules in the battery pack via a CAN bus. However, in actual production testing, ECUs using LIN communication protocols such as window control and motor motors also need to communicate with the BMS for testing. In this case, the key issue is how to ensure that different protocols can communicate and test properly.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
