Description
Technical field
The utility model relates to bus system, specifically is a kind of vehicle CAN bus system.
Background technology
Along with the development that auto industry is maked rapid progress, increasing electronic-controlled installation has been installed, for example engine electric-controlled system, anti-lock brake system (ABS), auto-manual wheel box (AMT), automatically controlled door and window, active suspension system etc. on the automobile.Each electronic-controlled installation all need be communicated by letter with actuator with many sensors, and also need communicate between each electronic-controlled installation.Information wire transmits if the exchange of every group of information is all used independently; Can cause the weight and the cost of the wire harness of electronic-controlled installation to increase sharply; Give the layout of car load and install and fix the great problem of having brought, also can cause the problem of information transmission interference between each electronic-controlled installation simultaneously.In order to address the above problem, be necessary to invent a kind of bus system that is exclusively used in electronic control device for vehicle communication.Yet still there is not a kind of like this bus system at present.
Summary of the invention
The utility model does not still have a kind of problem that is exclusively used in the bus system of electronic control device for vehicle communication at present in order to solve, and a kind of vehicle CAN bus system is provided.
The utility model is to adopt following technical scheme to realize: a kind of vehicle CAN bus system comprises amusement CAN network channel, power CAN network channel, vehicle body CAN network channel and diagnosis CAN network channel; Said amusement CAN network channel comprises amusement CAN bus, NAVSTAR, audiovisual system, air-conditioning system and radar for backing car display system; Said power CAN network channel comprises power CAN bus, control unit of engine, anti-lock braking system and auto-manual wheel box; Said vehicle body CAN network channel comprises vehicle body CAN bus, car body controller, chassis controller, tire pressure monitoring system, instrument display module, teleterminal system and drive recorder; Said diagnosis CAN network channel comprises diagnosis CAN bus and diagnose interface; Wherein, NAVSTAR, audiovisual system, air-conditioning system, radar for backing car display system all link to each other with car body controller through amusement CAN bus; Control unit of engine, anti-lock braking system, auto-manual wheel box all link to each other with car body controller through power CAN bus; Chassis controller, tire pressure monitoring system, teleterminal system, drive recorder all link to each other with car body controller through vehicle body CAN bus; The instrument display module links to each other with car body controller with vehicle body CAN bus through power CAN bus respectively; Diagnose interface links to each other with car body controller through diagnosis CAN bus; Be connected with sensor, power output module and switching value module on the car body controller respectively.
During work, car body controller is the Centroid of whole network, and it has following function: one, be responsible for the message exchange and the information processing of each CAN network channel.Two, gather vehicle body switching information, sensor information and have the power output function.The instrument display module is as the subsequent use Centroid and the display device at whole networking, and it has following function; One, do not receive the car body controller data within a certain period of time, will judge that car body controller damages, the instrument display module begins as backup network node processing important information, and the prompting driver keeps in repair.Two, the running status and the fault that show each system of car load.The external diagnostic device of diagnose interface is used to read the existing information and the failure message of amusement CAN network channel, power CAN network channel, vehicle body CAN network channel.In said process; The CAN bus design efficiently arbitration mechanism solve the transmission data collision problem; Make high-grade data obtain preferential transmission fast; The CAN bus also has error correction simultaneously, and the mistake that occurs in the time of can finding to detect data transmission is also corrected, and has improved the stability of system greatly.Based on this; The described a kind of vehicle CAN bus system of the utility model is through adopting the CAN network system of four network channels; Satisfied on the automobile each electronic-controlled installation to the requirement of different CAN network transmission speeds; Simultaneously it has reasonably distributed each network channel data, and the load factor of four network channels is controlled at reasonable levels, makes that the total system operation is more stable.Thus, the described a kind of vehicle CAN bus system of the utility model not only greatly reduces the use of wire harness, has made things convenient for the layout of car load wire harness and fixing, has thoroughly solved the problem of information transmission interference between each electronic-controlled installation simultaneously.
The utility model efficiently solves does not still have a kind of problem that is exclusively used in the bus system of electronic control device for vehicle communication at present, is applicable to the Vehicle Electronic Control field, is particularly useful for heavily blocking field of electric control.
