Abstract

The invention discloses a vehicle body control system based on area controllers, which comprises a central computer, a plurality of area controllers and an Ethernet transmission backbone network used for connecting each area controller and the central computer. The area controller comprises a left front vehicle body area controller, a right front vehicle body area controller and a rear vehicle body area controller, and the left front vehicle body area controller, the right front vehicle body area controller and the rear vehicle body area controller are in pairwise communication interaction connection through an Ethernet transmission backbone network. One domain controller is used for carrying out communication interaction on all the collected data and a central computer in a centralized manner through an Ethernet transmission backbone network; and a plurality of sub-control units for controlling actuators or sensors in respective corresponding areas are distributed on the left front vehicle body area controller, the right front vehicle body area controller and the rear vehicle body area controller.

Description

technical field [0001] The invention belongs to the field of vehicle body control, and in particular relates to a vehicle body control system based on an area controller. Background technique [0002] With the development of smart cars, there are more and more functions on the car. Correspondingly, there are more and more various controllers, actuators and sensors, which brings many problems to the electronic and electrical architecture of the car body. In the following aspects: 1. At present, there are dozens or even hundreds of electronic control units distributed on the car body, which brings huge challenges to the wiring harness design; 2. The power distribution of the electronic control unit is mainly based on the fuse box. If it is damaged, it cannot be self-recovered, and must be disassembled and replaced; 3. The demand for communication services on the vehicle continues to increase, and the data exchange rate of traditional gateways cannot meet the requirements of di...
