Description
Technical field
The present invention relates to the electric automobile field, relate in particular to electric automobile debug data field.
Background technology
Along with the development of new energy technology and automotive engineering, electric automobile more and more receives everybody concern, and its control technology is more and more advanced, and the cooperation between each parts becomes increasingly complex.And in the combined debugging performance history of car load, the effect of on-line debugging is also more and more important.Need to be by the BDM relevant with each parts (Background Debugging Mode during general on-line debugging, abbreviation BDM) interface directly is connected with computing machine, but during owing to on-line debugging, the restriction of the position of each parts and the signal of control chip is difficult to utilize BDM to debug easily.Be difficult to simulation car load environment and will need the parts debugged to take off to debug from car; (the Controller Area Network by CAN is also arranged, be called for short CAN) the clamping method receiving and assigned address is made amendment, but this method wants the commissioning staff to be very familiar to the problem that will debug, just can locate fast the address of the data that need modification, and how to revise.In case during the problem that did not run into before running into, often need to determine for a long time to cause data and its position of this problem.
Therefore necessaryly provide a kind of adjustment method, to overcome the problems referred to above.
Summary of the invention
The purpose that the present invention will reach is: a kind of electric automobile on-line debugging method based on real-time curve is provided, is intended to adapt to the parts of various models, the problem that can show intuitively again and the parameter that causes this problem, minimizing commissioning staff's labour intensity.
For achieving the above object, the present invention adopts following technical scheme: a kind of electric automobile on-line debugging method based on real-time curve, wherein said described method is with the integrated functional module with real-time curve demonstration car load control parameter and operational factor in the car load monitoring software, debug by the functional module that shows car load control parameter and operational factor with real-time curve, with CAN signal transmitting and receiving instrument USBCANII access Full-vehicle CAN bus network, connect car load monitoring software and the signal transmitting and receiving instrument USBCANII on the PC and start the car load monitoring software, when the commissioning staff need to search the position of breaking down and reason, the step of this method was as follows:
The first step. move the car load monitoring software, receive in real time and resolve the content of the CAN message on the CAN bus, open the real-time curve drafting module, draw the control parameter of each parts timed sending of car load and the real-time change curve of operational factor;
Second step. the commissioning staff finds out the curve abnormality point, thereby finds the moment of breaking down, the parameter that causes this fault and abort situation by observing the variation of curve;
The 3rd step. the commissioning staff debugs by analyzing, and behind the affirmation modification, sends order and revises parameter;
The 4th step. effect after observation was revised after this time debugging was finished, judge whether to proceed debugging, return the first step if continue debugging; Debugging finishes if debugging is finished then.
Advantage of the present invention and beneficial effect are: control parameter and the operational factor of not only can real-time online checking each parts of car load, also can check by real-time curve the change procedure of these state parameters, can be easy to like this to determine when, which parameter of which parts caused this time fault, then the commissioning staff can analyze the reason that breaks down accordingly, and use and modification order that these parts are appointed, revise the parameter in this part programs, to fix a breakdown.
Description of drawings
Fig. 1 is the FB(flow block) of electric automobile on-line debugging method of the present invention.
Fig. 2 is the hardware block diagram that electric automobile on-line debugging method of the present invention is rely and realized.
Embodiment
Consult Fig. 1 to Fig. 2, electric automobile on-line debugging method of the present invention is a kind of electric automobile on-line debugging method based on real-time curve, by the CAN bus car load is debugged, described adjustment method is with the integrated functional module with real-time curve demonstration car load control parameter and operational factor, by the functional module that shows car load control parameter and operational factor with real-time curve is debugged in the car load monitoring software.Its FB(flow block) as shown in Figure 1.
When the commissioning staff need to debug vehicle, with the Two Channels CAN Bus analyzer of CAN signal transmitting and receiving instrument USBCANII(based on USB) the access Full-vehicle CAN bus network, connect PC(Personal Computer) on car load monitoring software and signal transmitting and receiving instrument USBCANII and start the car load monitoring software.
When the commissioning staff need to search the position of breaking down and reason, the step of this method was as follows:
The first step. move the car load monitoring software, receive in real time and resolve the content of the CAN message on the CAN bus, open the real-time curve drafting module, draw the control parameter of each parts timed sending of car load and the real-time change curve of operational factor.
Second step. the commissioning staff finds out the curve abnormality point, thereby finds the moment of breaking down, the parameter that causes this fault and abort situation by observing the variation of curve.
The 3rd step. the commissioning staff debugs by analyzing, and behind the affirmation modification, sends order and revises parameter.
The 4th step. effect after observation was revised after this time debugging was finished, judge whether to proceed debugging, return the first step if continue debugging; Debugging finishes if debugging is finished then.
When the commissioning staff will revise the parameter of certain parts in the car because of needs, then send by monitoring software and revise order, this process is as follows:
The first step. monitoring software sends the CAN message of revising parameter command.
Second step. interior each parts judgement of car is also accepted relative modification order.
The 3rd step. revise designated parameter according to order request.
The 4th step. working procedure after the modification parameter.
The 5th step. the commissioning staff debugs according to ruuning situation.
The 6th step. judge whether to proceed debugging after this time debugging is finished, then return the first step if continue debugging; Debugging finishes if debugging is finished then.
