Embodiment Construction

[0018] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0019] The present invention takes a new model under research and development as an embodiment, which is defined as a mid-to-high-end luxury four-wheel-drive SUV, and adopts a series of new configurations and comfort devices. The following table lists the network node configuration of this embodiment:

[0020]

[0021] In addition, this embodiment is also equipped with some controllers that do not require high communication speed and low real-time requirements: window anti-pinch module (FLAM left front window anti-pinch module, FRAM right front window anti-pinch module, RLAM left rear Window anti-pinch module, RRAM right rear window anti-pinch module), reversing radar controller (Reverse Radar), rain sensor (Rain Sensor), these nodes use LIN bus communication in planning.

Abstract

The invention relates to a controller area network (CAN) and local interconnect network (LIN) bus-based vehicular network communication device. The CAN and LIN bus-based vehicular network communication device is characterized by comprising a CAN main network, a CAN subnetwork, an LIN and CAN and LIN gateways, wherein nodes in the CAN main network need to communicate with a plurality of other nodes; the nodes in the CAN subnetwok have high signal real-time and higher transmitting frequency, and occupy more occupied bandwidth; the nodes in the LIN have low communication speed and lower real-time; and the CAN and LIN gateways are integrated in a body control module (BCM) and exchange information required in communication between a CAN and the LIN.

Description

technical field [0001] The invention relates to a vehicle network communication system based on CAN / LIN bus, in particular to the planning and realization of a vehicle network communication system. Background technique [0002] With the rapid development of electronic technology and its wide application in the automotive industry, the degree of automotive electronics is getting higher and higher, and the traditional wiring harness connection method is far from meeting the needs of a large amount of information exchange and sharing inside and outside the car. Therefore, various network technologies suitable for the automotive environment have emerged as the times require. CAN is the abbreviation of Controller Area Network (Controller Local Area Network), and LIN is the abbreviation of Local Interconnect Network (Local Interconnect Network). [0003] According to the classification of SAE (society automotive engineering) network standards, automotive networks are roughly divi...
