Embodiment
Below in conjunction with accompanying drawing, structure and the principle of the vehicle control device of identifying based on address wire of the present invention are done further detailed elaboration.
The present invention can pass through to make the vehicle control device of same structure and principle, and each vehicle control device is installed in each control area of vehicle, all comprises the load that several are used for carrying out different control functions in each control area of vehicle.As shown in Figure 1, this vehicle control device comprises following each parts:
1) digital data acquisition unit, this unit is provided with the switching value interface, be connected with wire harness on the switching value interface, this wire harness is set as the geocoding line of this control area middle controller according to the coding of control area, this unit is used for reading the wire harness address, and this wire harness address is reached microprocessor;
2) analog acquisition unit, this unit is provided with the analog quantity interface, and this unit is used for gathering the parameter of this load, and this parameter is reached microprocessor;
3) analog line driver unit is used for driving this load and carries out the corresponding function of controlling;
4) CAN bus communication interface unit carries out information interaction by CAN bus and this load; And
5) microprocessor, be used for above-mentioned each unit is controlled, be used for judge whether the wire harness address of reading the digital data acquisition unit equals the address of certain control area, load place, be used for the load parameter that analog acquisition unit relatively gathers and whether meet the parameter request that microprocessor is preset.
As shown in Figure 2, driving cabin in figure, piggyback pod and member cabin can be considered each control area in vehicle, engine can be considered a load in piggyback pod, describes as example in the startup control (namely controlling function) of this engine (being load) in to carry out piggyback pod (being the control area).Before the installation controller, the wire harness of drawing in each controller can be set according to the coding of each control area, by the geocoding line of this wire harness as corresponding control area middle controller.Control area in general vehicle can be over 8, so usually adopt 12 stitch sockets as the switching value socket in practical application, wherein pin one-3 are the Address Recognition pin, 4-8 is the high level pin, 9-12 is the low level pin, if be less than in the situation of 4 control areas, can the part pin is idle.In this example, only relate to 3 control areas in Fig. 2, two pin design with the switching value interface that just can adapt to are the Address Recognition pin, and wire harness is set as the geocoding line of corresponding control area middle controller according to the coding of control area, thereby realize that corresponding installation site installs control module and realize respective control function.In this example, can be 11 with the code Design of driving cabin, be 10 with the code Design of piggyback pod, be 00 with the code Design in member cabin, and with each code storage in microprocessor, when being arranged on 3 controllers of the present invention in corresponding control area so, the wire harness that is connected with two pins of switching value socket in the driving cabin controller is carried out respectively unsettled setting, the wire harness address that reads, digital data acquisition unit is 11 o'clock, and can go out the control area that detects at present by microprocessor judges is driving cabin; The wire harness that is connected with first pin of switching value socket in the piggyback pod controller is carried out unsettled setting, and (switching value of this moment is high level 24V, be 1), the wire harness that is connected with second pin is connected to that on vehicle enclosure, (switching value of this moment is low level 0V, be 0), the wire harness address that reads, digital data acquisition unit is 10 o'clock, and can go out the control area that detects at present by microprocessor judges is piggyback pod; The wire harness that is connected with two pins of switching value socket in the controller of member cabin is connected to respectively on the outer bridge of vehicle, the wire harness address that reads, digital data acquisition unit is 00 o'clock, can go out the control area that detects at present by microprocessor judges and be the member cabin.
After the vehicle power-up initializing, controller is realized Address Recognition and is carried out the control function of respective load.this example is controlled to be example with the startup of carrying out engine in piggyback pod, concrete steps are: when at first the digital data acquisition unit reads the wire harness address and be 11, go out to be driving cabin by microprocessor judges, engine is not in this control area, so continuation addressing, again reading the wire harness address is 10, go out to be piggyback pod by microprocessor judges, the CAN bus communication interface is obtained startup command and the current state (whether in running order) of engine by the CAN bus, as in running order in engine, by the CAN bus with result feedback to the user, and stop the control flow of this starting engine, be in not under duty as engine, gather the parameter of this engine by the analog acquisition unit, and this parameter is sent to microprocessor, by microprocessor, engine parameter default in this parameter and microprocessor (this parameter can make rotating speed, oil consumption of engine etc.) is compared, parameter as engine meets the requirements, by analog line driver unit drives engine start, parameter as engine is undesirable, by the CAN bus with result feedback to the user, and stop the control flow of this starting engine.
What the strand design of this invention by the Address Recognition in control module initialization procedure design and control module realized identical control module completes the different control units function.Thereby realize control module to be arranged on diverse location and become the purpose of different control modules.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although with reference to above-described embodiment, the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can modify or be equal to replacement the specific embodiment of the present invention, and do not break away from any modification of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of claim scope of the present invention.
