The invention relates to an electronic control system framework for a vehicle body, which has flexible and reliable control and less required wiring harness. The invention has the technical scheme that the electronic control system framework for the vehicle body is characterized by comprising a plurality of electronic control modules; each control module can drive a corresponding load; and the control modules are connected with each other through a bus, wherein a front vehicle body control module is a main node on the bus.
Description
Technical field
The present invention relates to a kind of electronic control system framework for vehicle body.
Background technology
At present, the existing auto body modes that adopt centralized control just adopt the integrated control of car body controller, drive each device of vehicle body more.Adopt the car body controller integrated level of centralized control high more, used wire harness is just many more, and volume is also big more, brings power consumption, heat dissipation problem thus, if certain components and parts damages, must change whole car body controller.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of electronic control system framework for vehicle body, and control flexibility and reliability, required wire harness is few.
Realize the technical scheme of the object of the invention:
A kind of electronic control system framework for vehicle body is characterized in that: have a plurality of ECU electronic control unit, each control module can drive corresponding load, and each control module is by total wire joint, and wherein the front body control module is the major joint on the bus.
ECU electronic control unit is made of front body control module, back Body control module, left front vehicle window control module, left back vehicle window control module, right front vehicle window control module, right back vehicle window control module.
The position of each ECU electronic control unit is front body, back vehicle body, left front vehicle window, left back vehicle window, right front vehicle window, the right back vehicle window zone of corresponding automobile respectively.
Left front vehicle window control module, left back vehicle window control module, right front vehicle window control module, right back vehicle window control module are connected with the front body control module by the LIN bus, and the front body control module is the major joint of LIN bus.
The front body control module is passed through the total wire joint of CAN with the back Body control module, and the front body control module is controlled the back Body control module.
The front body control module can receive wiper switch, lighting switch, horn switch, boot switch, back Curtain switch or driver side car window switch signal, but windscreen wiper, car light, loudspeaker or wind screen defrosting operation are carried out in the load of front body control module direct drive.
The signal input part of back Body control module signal output termination boot release motor, back curtain control motor or car door door-lock motor.
The signal output part of left front vehicle window control module, left back vehicle window control module, right front vehicle window control module, right back vehicle window control module connects corresponding vehicle window control motor respectively, and the signal input part of left back vehicle window control module, right front vehicle window control module, right back vehicle window control module connects corresponding car window switch respectively.
The beneficial effect that the present invention has:
The present invention uses distributed control mode, according to functional area a plurality of ECU electronic control unit are set, wherein the front body ECU electronic control unit is controlled other ECU electronic control unit, each ECU electronic control unit can drive corresponding vehicle body device, and be arranged in corresponding vehicle body zone, make bodywork system control reliable more rapidly, can effectively reduce strand design and body structure design-calculated complexity simultaneously.The present invention adopts the design of hardware and software platform, by the increase scale, can effectively reduce average unit cost.

The specific embodiment
As shown in Figure 1, ECU electronic control unit is made of front body control module, back Body control module, left front vehicle window control module, left back vehicle window control module, right front vehicle window control module, right back vehicle window control module, the position of each ECU electronic control unit is front body, back vehicle body, left front vehicle window, left back vehicle window, right front vehicle window, the right back vehicle window zone of corresponding automobile respectively, the input and output of each module controls respective regions.
As shown in Figure 2, left front vehicle window control module, left back vehicle window control module, right front vehicle window control module, right back vehicle window control module are connected with the front body control module by the LIN bus, and the front body control module is the major joint of LIN bus.Four vehicle window control modules are only controlled automatic window, because the requirement that automatic window was controlled the time is not very high, semaphore is not very big, therefore adopt the total wire joint of the low LIN of cost.
The front body control module is passed through the total wire joint of CAN with the back Body control module, and the front body control module is controlled the back Body control module.Require speed of response fast during semaphore Datong District that forward and backward Body control module transmits, so the two is by the total wire joint of CAN.The front body control module is the gateway of CAN bus and LIN bus, is the major joint in the LIN bus simultaneously, is responsible for the message scheduling of whole LIN network.
As shown in Figure 3, the front body control module can receive wiper switch, lighting switch, horn switch, boot switch, back Curtain switch or driver side car window switch signal, but windscreen wiper, car light, loudspeaker or wind screen defrosting operation are carried out in the load of front body control module direct drive.
As shown in Figure 4, the signal input part of back Body control module signal output termination boot release motor, back curtain control motor or car door door-lock motor, the door lock of four car doors of back Body control module controlling and driving and electric trunk, back curtain.
As shown in Figure 5, the corresponding vehicle window control of the signal output termination of vehicle window control module (left front vehicle window control module, left back vehicle window control module, right front vehicle window control module, right back vehicle window control module) motor, the signal input part of vehicle window control module (left back vehicle window control module, right front vehicle window control module, right back vehicle window control module) connects corresponding car window switch
Press and be positioned near the boot release switch of chaufeur, be arranged near the front body control module of instrument carrier panel and at first detect the boot switch signal, judgement is also sent the baggage container switch order, switch order sends near the back Body control module that is positioned at the vehicle body C post by the CAN bus, and back Body control module drives the boot release motor according to switch order.
Press and be positioned at the driver side car window switch, the front body control module at first detects on-off signal, judges that switch also sends instruction, and instruction sends to corresponding vehicle window control module by the LIN bus, and the vehicle window control module drives corresponding vehicle window control motor.
Press copilot's sidecar window (right front vehicle window), right back vehicle window or left back car window switch, corresponding vehicle window control module detects the input of on-off signal, drives corresponding vehicle window control motor.
