Structure-simplified vehicle-mounted communication network architecture

Abstract

The invention discloses a structure-simplified vehicle-mounted communication network architecture which comprises at least one sensing equipment arranged on a vehicle body, the sensing equipment is connected with a combination instrument through a communication line, a gateway routing chip is integrated on the combination instrument, and the combination instrument is connected with a vehicle CAN network. According to the scheme, the gateway routing chip is integrated on the combination instrument; an algorithm program executed by the ADAS controller is installed, and the combination instrumentis adopted for replacing functions of the existing gateway controller, the ADAS controller and the ADAS external visual display screen. Compared with the prior art, the network architecture has the following advantages that a special gateway controller, an ADAS controller and a visual reminding screen are canceled, and the cost pressure of economical vehicle models is reduced; the whole vehicle communication network structure is simplified, the bus load rate is reduced, the failure rate is reduced, the advantages of a current combination instrument in operation and display are fully utilized,reasonable distribution of resources is achieved, meanwhile, the design difficulty is reduced, and the method is easier to achieve compared with an original communication network.

Description

technical field [0001] The invention relates to the field of vehicular communication networks, in particular to a structure-simplified vehicular communication network architecture. Background technique [0002] At present, with the technological progress of Advanced Driver Assistant System (ADAS), more and more automobile OEMs are applying it to mass-produced models, and it has become the standard configuration of smart models in the new era. ADAS functions mainly rely on radar and cameras. The vehicle network architecture has become more complex, the amount of data transmission has increased greatly, and there are higher requirements for the vehicle bus. [0003] as attached figure 1 As shown, the current mainstream solution for car manufacturers is to configure a dedicated gateway controller for data routing and separate the ADAS domain from the vehicle domain. The sensing device is interconnected with the ADAS controller and the visual reminder screen through the CAN li...

Problems solved by technology

[0004] For some low-end models, especially new energy models with extremely strict cost control, dedicated gateway controllers, ADAS controllers and external visual warning screens will cause great cost pressure, while low-cost gateway controllers and ADAS controllers Devices will bring great security risks, and the contradiction between cost and security needs to be adjusted urgently
