Host processing system is the core of whole automobile electronic information platform, adds that by central processing unit other peripherals constitute, as high speed processor, liquid crystal display, mass-memory unit etc.

Central processing unit can adopt automobile PC or flush bonding processor as core, is connected with all subsystem, submodule by the CAN bus.Its external input equipment has keyboard, touch-screen, mouse, microphone etc., and output device has LCDs, sound equipment earphone interface etc.Also have jumbo memory device simultaneously, be used for the resource of stored GIS information, various parameter, entertainment systems etc.

Subsystem, submodule mainly comprise:

Power transmission subsystem: engine management module, transmission control module, suspension control module, traction control module and ABS+ASR control module.

Body subsystem: car door administration module, vehicle window administration module, car light administration module, seat control module, rear-view mirror control module and air conditioning managing module etc.

Secure subsystem: air bag administration module, securing band administration module, child belt identification module, acceleration sensor module, air bag controlled module and TPMS tire pressure detection subsystem.

Vehicle body information subsystem: GPS global positioning satellite subsystem, car phone module, audio and video information module, radio module and Internet link block.

The software of host processing system mainly contain CAN bus communication control and, corresponding driving program and information processing and man-machine interface, by the conversion between CAN adapter realization CAN bus and the pci bus, on the basis of data communication, data are handled computing, realize the control of subsystem and reflect the running status of each subsystem by the various way of outputs (as audio frequency, video etc.).

Host processing system can replace traditional instrument panel by man-machine interface, on display interface, can comprise all parameter informations relevant with automobilism, as: System self-test, GPS navigation, TPMS monitoring, infosystem, network system, Body Control, condition of the vehicle demonstration etc.All information demonstrations all are embodied on the liquid crystal display.
