Description

A kind of electronlmobil body control system
Technical field
The utility model relates to a kind of autobody control system, especially relates to a kind of electronlmobil body control system.
Background technology
At present, (Body Control Module BCM) mainly comprises three types to the auto body control module: distributing, centralized and distributed (bus type).
Distributing BCM by several dispersions independently electronic control unit (ECU) form, each ECU controls a certain function separately.Owing to do not communicate by letter between each ECU, be not easy to the lifting of information sharing and function, distributing BCM can't realize powerful controllable function.
Centralized BCM adopts powerful Central Control Module (CCM).All terminators (gate, lamp control, panel, catadioptre, vehicle window, windscreen wiper, defrosting etc.) are all through lead and Central Control Module (CCM) direct connection.The wire harness of centralized control is too concentrated, and installation wiring is complicated, and power consumption is many, and heat dissipation problem is outstanding, and the possibility of makeing mistakes is bigger, and reliability is not fine, in case certain components and parts among the BCM are damaged, just must change whole BCM.
Each basic load among the distributed BCM is all controlled by an ECU, is connected, communicates by letter through LIN and/or CAN between each ECU and the Central Control Module (CCM).The shortcoming of distributed BCM is that ECU quantity is too many, and cost is high.
The raising day by day of Along with people's environmental protection consciousness, electronlmobil have become one of target of automobile industry development.Electronlmobil BCM mainly adopts distributed BCM framework at present, but the too high shortcoming of its cost still exists.
The utility model content
The purpose of the utility model be exactly provide a kind of in order to overcome the defective that above-mentioned prior art exists and save electric energy, reduce wire harness, wiring is convenient, save cost, electronlmobil body control system easy to maintenance.
The purpose of the utility model can realize through following technical scheme:
A kind of electronlmobil body control system; Comprise the CAN bus; It is characterized in that; Also comprise respectively with CAN bus bonded assembly before BCM, back BCM, preceding BCM control load module, back BCM control load module, be positioned at of the load of car front portion by preceding BCM control, be positioned at of the load of car rear portion by back BCM control; BCM control load module is connected with preceding BCM before described, and described back BCM control load module is connected with back BCM.
BCM, back BCM include control unit and fuse box before described.
The described car front portion that is positioned at comprises driver door, preceding vehicle window, preceding windscreen wiper and front car light by the load that preceding BCM controls.
The described car rear portion that is positioned at comprises tail gate, vehicle rear window, back windscreen wiper, back car light and baggage container by the load of back BCM control.
Compared with prior art, the utlity model has following advantage:
1, saves electric energy: because BCM is divided into preceding BCM and back BCM; BCM control load module and back BCM control load module before BCM control load module also is divided into; Distance between two BCM and each load is nearer; Distance between two BCM and BCM control load module is also nearer, thereby wire harness reduces, and current draw is few.
2, reduce wire harness, wiring conveniently: can know that by advantage one wire harness reduces, simultaneously, other CAN nodes of CAN bus in the native system and car load are shared; Thereby do not increase the wire harness of CAN bus, generally speaking, the wire harness of car load reduces; And orderly before and after the wire harness distribution, wiring is convenient.
3, save cost: because the wire harness minimizing, thereby cost has reduced.Simultaneously, the BCM and the fuse box that separate originally are integrated into a BCM, have also reduced cost.
4, easy to maintenance: as, to make things convenient for diagnostic equipment to insert and safeguard owing to adopt the CAN bus.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
Because the electric energy of electronlmobil is extremely valuable, when its power saving performance is design electronlmobil BCM, the factor of overriding concern.The utility model combines the construction characteristic of centralized BCM and distributed BCM, and based on saving electric energy, reduce wire harness, practicing thrift cost or the like consideration, the overall situation has designed a kind of electronlmobil body control system.
As shown in Figure 1; A kind of electronlmobil body control system; Comprise the CAN bus; Also comprise respectively with CAN bus bonded assembly before BCM1, back BCM2, preceding BCM control load module 3, back BCM control load module 4, be positioned at of the load of car front portion by preceding BCM control, be positioned at of the load of car rear portion by back BCM control; BCM control load module 3 is connected with preceding BCM1 before described, and described back BCM control load module 4 is connected with back BCM2.The described car front portion that is positioned at comprises driver door, preceding vehicle window, preceding windscreen wiper, front car light by the load that preceding BCM controls.The described car rear portion that is positioned at comprises tail gate, vehicle rear window, back windscreen wiper, back car light, baggage container by the load of back BCM control.
BCM control load module 3 or CAN bus signals before preceding BCM1 accepts, the process Algorithm Analysis, behind the integrated dispatch, the output control signal.Wherein, relate to by the load of preceding BCM control, directly by preceding BCM1 through lead output.Relate to by the load of back BCM control, export to back BCM2 through the CAN bus by preceding BCM1.
Back BCM2 accepts back BCM control load module 4 or CAN bus signals, through Algorithm Analysis, and behind the integrated dispatch, the output control signal.Wherein, relate to by the load of back BCM control, directly by back BCM2 through lead output.Relate to by the load of preceding BCM control, BCM2 exports to preceding BCM1 through the CAN bus by the back.
Include control module and fuse box among preceding BCM1 and the back BCM2.Control module is accepted input, and the operation respective algorithms is exported control signal, and carries out the trouble diagnosing of respective load.Fuse box guarantees that each body electric system power supply is separate, does not disturb mutually.
