Embodiment 1

[0060] Such as figure 1 As shown, the vehicle control system with domain control function includes a central domain controller 100 , a display device 200 , a vehicle electronic module 300 and a gateway 400 .

[0061] The central domain controller 100 has a central processing unit 101 , an input signal processing unit 102 , an output driving circuit unit 103 , an LVDS interface 104 , a CAN interface 105 , and an Ethernet communication interface 106 . Specifically, the central domain controller 100 in this embodiment may use an existing commercially available vehicle body domain controller.

[0062] The display device 200 is connected to the central domain controller through the LVDS interface.

[0063] The vehicle electronic module 300 communicates with the central domain controller through Ethernet.

[0064] The gateway 400 is connected to the central domain controller through the CAN interface and Ethernet,

[0065] Wherein, the input signal processing unit receives and pr...

Embodiment 2

[0067] On the basis of Embodiment 1, further, the display device in this embodiment includes three types: a combination instrument display screen, a central control display screen, and a HUD display screen. If necessary, it can also be expanded by the user. As long as it is a display device with LVDS interface, it can be connected.

[0068] The central domain controller receives the signal forwarded by the gateway through the CAN interface and is processed by the input signal processing unit and the output drive circuit unit, and then sent to the combination instrument display screen, the central control display screen and the HUD display through the LVDS interface screen to display.

Embodiment 3

[0070] On the basis of Embodiment 1 or 2, further, the vehicle-mounted electronic module described in this embodiment is a surround-view camera, a V2X module, a driving recorder, a night vision device, and a T-box,

[0071] The central domain controller receives the signal collected by the on-vehicle electronic module 300 through Ethernet, processes it by the input signal processing unit and the output driving circuit unit, and sends it to the corresponding display device for display through the LVDS interface.

Abstract

The invention discloses a vehicle-mounted control system with a domain control function and an upgrading method, and relates to the technical field of automotive electronics. The system compires a central domain controller and a display device, the display device is connected with the central domain controller through an LVDS interface; a vehicle-mounted electronic module is connected with the central domain controller through the Ethernet; and a gateway connected with the central domain controller through a CAN interface and the Ethernet, wherein the input signal processing unit receives andprocesses signals of the gateway and the vehicle-mounted electronic module, and then the output driving circuit unit sends the signals to corresponding display devices for display through an LVDS interface and sends the signals to the vehicle-mounted electronic module for execution through an Ethernet communication interface. Due to the fact that the central domain controller is introduced, vehicle-mounted electronic modules, display equipment and the like which can use the same interface and communication protocol are concentrated, the interface and the communication protocol can be degenerated, the mutual dependence between wire harnesses and parts is reduced, a vehicle-mounted control system of an automobile is safer, and the flexibility of the system is improved.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a vehicle-mounted control system with a domain control function. Background technique [0002] With the development of automotive electronics technology, there are more and more electrical components on the car, and different components need to interact to achieve a function. [0003] Specifically, the central controller will be connected with various display devices (instrument display, central control display, etc.) Connection, used to collect external information for processing and control. Further, a remote communication gateway will be introduced to communicate, and multiple resources will be integrated to form a smart car. [0004] Obviously, if the above peripheral devices (display devices, on-board electronic modules, gateways, etc.) These will cause the electronic device part of the car to become complicated and redundant, and occupy too much space. ...
