Embodiment
Below in conjunction with accompanying drawing the structure and the principle of the vehicle control device of discerning based on address wire according to the 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, in each control area of vehicle, all comprises the load that several are used to carry out different control functions.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, is connected with wire harness on the switching value interface, according to the coding of control area the geocoding line of this wire harness as this control area middle controller is set; This unit is used to read 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 to gather the parameter of this load, and this parameter is reached microprocessor;
3) analog line driver unit is used to drive this load and carries out the control corresponding function;
4) CAN bus communication interface unit carries out information interaction through CAN bus and this load; And
5) microprocessor; Be used for above-mentioned each unit is controlled; Be used to judge whether the wire harness address that the digital quantity collecting unit is read equals the address that certain load belongs to the control area, and whether the load parameter that is used for being gathered comparison analog acquisition unit meets the preset parameter request of microprocessor.
As shown in Figure 2; Driving cabin among the figure, piggyback pod and member cabin can be considered each control area in the vehicle; Engine can be considered a load in the piggyback pod, is that example describes at this with the start-up control (being control function) of carrying out engine (being load) in the piggyback pod (being the control area).Before the installation and control device, the wire harness of drawing in each controller can be set, according to the coding of each control area through the geocoding line of this wire harness as corresponding control area middle controller.Control area in the general vehicle can be above 8; So adopt 12 stitch sockets in the practical application usually as the switching value socket; Wherein pin one-3 is the Address Recognition pin, and 4-8 is the high level pin, and 9-12 is the low level pin; If be less than under the situation of 4 control areas, can the part pin is idle.In this example; Only relate to 3 control areas among Fig. 2; Two pin design with the switching value interface that just can adapt to are the Address Recognition pin; And the geocoding line of wire harness as corresponding control area middle controller is set, thereby realize that installation and control unit, corresponding installation site realizes respective control function according to the coding of control area.In this example; Can be 11 with the code Design of driving cabin; With the code Design of piggyback pod is 10, is 00 with the code Design in member cabin, and with each code storage in microprocessor; When being installed in 3 controllers of the present invention in the corresponding control area so; The wire harness that links to each other with two pins of switching value socket in the driving cabin controller is carried out unsettled setting respectively, and then the wire harness address that reads, digital data acquisition unit is 11 o'clock, and can go out present detected control area through microprocessor judges is driving cabin; The wire harness that links to each other 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 links to each other with second pin is connected to that (switching value of this moment is low level 0V on the vehicle enclosure; Be 0); Then the wire harness address that reads, digital data acquisition unit is 10 o'clock, and can go out present detected control area through microprocessor judges is piggyback pod; The wire harness that links to each other with two pins of switching value socket in the controller of member cabin is connected to respectively on the outer bridge of vehicle; Then the wire harness address that reads, digital data acquisition unit is 00 o'clock, and can go out present detected control area through microprocessor judges is the member cabin.
Behind the vehicle power-up initializing, controller is realized Address Recognition and is carried out the control function of respective load.This example is an example with the start-up control of carrying out engine in the piggyback pod, and concrete steps are: when the digital data acquisition unit at first reads the wire harness address when being 11, go out to be driving cabin through microprocessor judges; Engine is not in this control area; So the continuation addressing, reading the wire harness address once more is 10, goes out to be piggyback pod through microprocessor judges; Then the CAN bus communication interface is obtained the startup command and the current state (whether in running order) of engine through the CAN bus; In running order like engine, then the result is fed back to the user, and stop the control flow of this starting engine through the CAN bus; Be in not under the duty like engine; Then gather the parameter of this engine through the analog acquisition unit; And this parameter is sent to microprocessor; By microprocessor engine parameter preset in this parameter and the microprocessor (this parameter can make rotating speed, oil consumption of engine or the like) is compared, meet the requirements like the parameter of engine, then by analog line driver unit drives engine start; Parameter like engine is undesirable, then through the CAN bus result is fed back to the user, and stops the control flow of this starting engine.
This invention realizes the completion different control units function of identical control module through the design of the Address Recognition in the control module initialization procedure and the strand design of control module., the realization control module becomes the purpose of Different control unit thereby being installed in diverse location.
Should be noted that at last: above embodiment is only in order to technical scheme of the present invention to be described but not to its restriction; Although the present invention has been carried out detailed explanation with reference to the foregoing description; Under the those of ordinary skill in field be to be understood that: still can specific embodiments of the invention make amendment or be equal to replacement; 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 the claim scope of the present invention.
