Abstract
The invention discloses a kind of active diagnosing method of whole electric vehicle failure, belong to electric vehicle engineering field, including：S1, master system are monitored to the current complete vehicle fault of selection, and are sent fault diagnosis and instructed to entire car controller；S2, entire car controller read the failure code of current complete vehicle fault according to the fault diagnosis instruction received, and start Diagnostic Strategy corresponding with the failure code；S3, entire car controller send the current complete vehicle fault reason-code being diagnosed to be to master system；S4, master system search the reason for current complete vehicle fault occurs and fault solution in database and carry out text importing according to the current complete vehicle fault reason-code received.By the communication of master system and entire car controller, active diagnosing is carried out to complete vehicle fault, the accuracy rate and efficiency of fault diagnosis is improved.
Description
Technical field
The present invention relates to electric vehicle engineering field, more particularly to a kind of active diagnosing method of whole electric vehicle failure.
Background technology
With the fast development of electric automobile, the production of the high-volume electric motor coach of vehicle factory face middle speed of production it is slow,
The problem of quality of production uniformity difference and difficult vehicle diagnosis.Traditional electric motor coach Breakdown Maintenance, mainly by vehicle factory
Personnel after sale, depth failure even will rely on the technical staff of vehicle factory and could solve, and the difficult in maintenance and cycle is long, causes whole
Car Breakdown Maintenance efficiency is low, accuracy rate is low.
The content of the invention
It is an object of the invention to provide a kind of active diagnosing method of whole electric vehicle failure, to improve complete vehicle fault
Maintenance efficiency.
To realize object above, the present invention provides a kind of active diagnosing method of whole electric vehicle failure, and this method includes：
S1, master system are monitored to the current complete vehicle fault of selection, and are sent fault diagnosis and instructed to entire car controller；
S2, entire car controller read the failure code of current complete vehicle fault according to the fault diagnosis instruction received, and start with
The corresponding Diagnostic Strategy of the failure code；
S3, entire car controller send the current complete vehicle fault reason-code being diagnosed to be to master system；
S4, master system search current complete vehicle fault according to the current complete vehicle fault reason-code received in database
The reason for generation and fault solution simultaneously carry out text importing.
Further, above-mentioned Diagnostic Strategy, including：
Start the failure corresponding with the current complete vehicle fault code and produce simulation process；
In simulation process, monitoring obtains the real causes of each fault message.
Further, communicated between above-mentioned master system and above-mentioned entire car controller by controller LAN.
Further, the above method also includes：
When vehicle is built, entire car controller is reserved with active diagnosing interface.
Compared with prior art, there is following technique effect in the present invention：The present invention passes through master system and full-vehicle control
Device coordinates, and complete vehicle fault active diagnosing interface is reserved when Full Vehicle System is built, by operating master system to vehicle control
Device processed sends active diagnosing instruction, you can carries out active analysis to whole electric vehicle failure by entire car controller, obtains vehicle
The reason for failure occurs.Its diagnosis effect science is objective, with higher accuracy rate and efficiency, is conducive to whole electric vehicle failure
Maintenance and easy to spread.

Embodiment
In order to illustrate further the feature of the present invention, please refer to the following detailed descriptions related to the present invention and accompanying drawing.Institute
Accompanying drawing is only for reference and purposes of discussion, not for being any limitation as to protection scope of the present invention.
As shown in figure 1, present embodiment discloses a kind of active diagnosing method of whole electric vehicle failure, this method is included such as
Lower step S1 to S4：
S1, master system are monitored to the current complete vehicle fault of selection, and are sent fault diagnosis and instructed to entire car controller；
It should be noted that whole electric vehicle failure includes electric fault in high pressure, driving faults, hangs shelves switch failure, charging event
The functional faults such as barrier, while the equipment fault of also each high-tension apparatus.During actually diagnosis, master system, which can be chosen, to be needed
The failure to be monitored, and start the active diagnosing instruction of the failure, the failure to selection carries out active diagnosing.
S2, entire car controller read the failure code of current complete vehicle fault according to the fault diagnosis instruction received, and open
Move Diagnostic Strategy corresponding with the failure code；
It should be noted that carrying the failure for being currently needed for diagnosis in the failure active diagnosing instruction that master system is sent
Code, failure code has uniqueness, and entire car controller recognizes the need for the failure of diagnosis according to failure code, and starts corresponding
Diagnostic Strategy.
S3, entire car controller send the current complete vehicle fault reason-code being diagnosed to be to master system；
S4, master system search current complete vehicle fault according to the current complete vehicle fault reason-code received in database
The reason for generation and fault solution simultaneously carry out text importing.
Further, as shown in Fig. 2 above-mentioned Diagnostic Strategy, including：
Start the failure corresponding with the current complete vehicle fault code and produce simulation process；
In simulation process, monitoring obtains the real causes of each fault message.
Specifically, entire car controller identifies the failure for being currently needed for diagnosis, then to this when receiving failure code
The generation process of failure is simulated, and then finds out the real causes of failure generation in simulations.
Below by taking Fig. 3 to Fig. 4 as an example, illustrate the diagnostic process of specific failure：
Fig. 3 shows the active diagnosing process of electric fault in high pressure, and Fig. 4 shows the active diagnosing process of driving faults, due to
The reason for driving faults, is more, and failure cause is investigated one by one can improve the accuracy of diagnosis, but in actual applications, can also
Common failure cause is investigated, to improve diagnosis efficiency.In the application, code has uniquely the reason for every kind of failure
Property, master system code according to the reason for failure can find cause description corresponding with the reason-code in database
And corresponding solution explanation, and described above is shown, so that Breakdown Maintenance personnel are carried out with failure cause investigation, event
Hinder solution etc. to instruct.
Further, communicated between above-mentioned master system and above-mentioned entire car controller by controller LAN.
Wherein, currently transmitted fault diagnosis instruction can be converted into CAN communication instruction transmission to entire car controller by master system.It is whole
Failure Producing reason code is converted into CAN communication instruction and sent to master system by vehicle controller.Here CAN communication refers to
Order belongs to CAN communication mechanism, equivalent to one communications protocol.
Further, the present embodiment is when Full Vehicle System is built, and entire car controller is reserved with active diagnosing interface, to receive
The diagnostic instruction of master system performs fault diagnosis.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
