Description

CAN-BUS practical training platform

Technical Field

The utility model relates to a real standard platform of CAN-BUS.

Background

CAN-bus (controller Area network), i.e. controller Area network, is one of the most widely used field buses in the world. Initially, CAN-bus was designed to communicate as a microcontroller in the automotive environment, exchanging information between the onboard electronic control units ECUs to form the automotive electronic control network. At present, the application of the CAN-BUS on vehicles is more and more popular, and the CAN-BUS is not only limited to high-grade vehicles (such as Polo, Baolai and Passat), but also more and more equipped on medium-grade vehicles (such as the public Tugan in Shanghai). The practical training platform selects a popular Passat CAN-BUS local area network communication system, and the comfortable system comprises an s-comfortable system electric control unit, an electric rearview mirror, a central control lock, an electric door and window, an anti-theft system and other elements.

A large number of wire harnesses are buried in a cabin and a body of a traditional car to transmit signals collected by sensors, the number of the wire harnesses in the car CAN be greatly reduced by applying the CAN-BUS BUS technology, coordinated operation and information sharing of all systems of the car CAN be guaranteed, and the car is safer, more comfortable and more reliable to run.
