Description

Vehicle-mounted high-speed bus LAN and CAN communication system device

Technical Field

The utility model relates to an automobile vehicle mounted network technical field, in particular to on-vehicle high-speed bus LAN, CAN communication system device.

Background

With the rapid development of electronic technology and the wide application thereof in the automobile industry, the degree of automobile electronization is higher and higher, and the traditional wire harness connection mode is far from meeting the requirements of exchanging and sharing a large amount of information inside and outside the automobile. Therefore, various network technologies suitable for the automotive environment have been developed. CAN is an abbreviation of Controller Area Network (Controller module Area Network), and LAN is an abbreviation of local Area Network (local Area Network).

The CAN bus was originally developed by Robert Bosch GmbH in the 80's of the 20 th century. Today, it is supported by many integrated circuit and subsystem manufacturers and is used in all modern automobiles. The CAN bus allows different controller modules or processors on the bus to communicate with each other via messages transmitted on the bus. It uses a priority-ordering approach so that low priority messages do not interfere with high priority messages. The transmission rate of the CAN bus is less than 1 Mbps, and the message length (CAN frame) is typically 50 to 100 bits.

The existing automobiles mostly adopt low-speed communication modes such as LIN communication, CAN communication, FlexRay communication and the like, and various high-speed data are transmitted by using the vehicle-mounted high-speed bus LAN and CAN communication system device due to the general speed characteristics, the diversity of the communication modes and the application scene limitations (mainly applied to the control of electric doors and windows, seat adjustment, light illumination and the like, the mainstream technology is LIN; and the mainstream technology is CAN; and the systems of an electronic vehicle information center, fault diagnosis, instrument display, an airbag and the like, the mainstream technology is CAN). For example: navigation systems and controls, etc. It CAN be used as a CAN bus in the same way and at the same time provide more bandwidth. Ethernet is an ideal alternative to CAN bus, but because of its high cost per node, it may not replace CAN bus, but rather supplement it.

Meanwhile, the existing communication device needs to be stably fixed at a working position when working.

Therefore, a vehicle-mounted high-speed bus LAN and CAN communication system device is proposed.
