Commercial vehicle vehicle-mounted electronic network system

Abstract

The invention discloses a commercial vehicle vehicle-mounted electronic network system which comprises an elemental network module, a chassis network expansion module and a vehicle body network expansion module. The elemental network module comprises various instruments, a vehicle-mounted recorder and a diagnosis interface. The chassis network expansion module comprises an auxiliary safety system, an EPS, an electric control suspension, an SCR, an engine antitheft system, an EMS, a retarder, a TCU, an angle sensor, an ESP, an ABS and an ASR. The vehicle body network expansion module comprises a switch module, a door and window module, a tire pressure detection module, a vehicle control module, vehicle backing radar and an automatic air conditioner. The elemental network module, the chassis network expansion module and the vehicle body network expansion module are connected through a gateway. By the adoption of the commercial vehicle vehicle-mounted electronic network system, all the instruments and devices on a vehicle are connected through the gateway, a central processing unit is used for centralized processing, the number of electric control units and the number of sensors are reduced, wiring harnesses are reduced, and resource sharing is achieved.

Description

technical field [0001] The invention relates to a vehicle electronic system. Background technique [0002] The rapid development of automotive electronics technology. The number of electronic control systems on automobiles has increased sharply, and their functions have become increasingly complex. The traditional point-to-point communication method connects the electronic control unit and load equipment, which will inevitably introduce a large number of wiring harnesses. As a result, the following problems are brought about: 1) The rapid increase of wiring harnesses makes it more difficult to route wiring in limited car space, which limits the expansion of functions; 2) A large number of wiring harnesses increases the weight of the car; 3) The introduction of a large number of sensors and connectors leads to reduced reliability. Contents of the invention [0003] The purpose of the present invention is to provide an on-board electronic network system for commercial vehi...
