In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
Technical solution be clearly and completely described, it is clear that described embodiments are some of the embodiments of the present invention, rather than
Whole embodiments.The component of embodiments of the present invention, which are generally described and illustrated herein in the accompanying drawings can be matched with a variety of different
It sets to arrange and design.Therefore, the detailed description of the embodiment of the present invention provided in the accompanying drawings is not intended to limit below
The range of claimed invention, but it is merely representative of selected embodiment of the invention.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work, belongs to the present invention
The range of protection.
Troubleshooting test can only be carried out on rack or on real vehicle using manual mode for existing, test process is numerous
Trivial, test repeatability and Test coverage degree are poor, cause the problem that test result is undesirable, the embodiment of the invention provides one
Kind automated diagnostic methods, devices and systems, below first describe to automated diagnostic method of the invention in detail.
Embodiment one
A kind of automated diagnostic method is present embodiments provided, this method is applied to hardware-in-the-loop test system
Host computer in (HIL, hardware-in-the-loop), and hardware-in-the-loop test system includes ECU, ECU with it is upper
Machine connection.Fig. 1 show the flow chart of automated diagnostic method, this method comprises:
Step S102 calls diagnosis algorithm library, analyzes the diagnostic message being stored in advance, obtain diagnostic command.Its
In, diagnostic message includes the automatic test sequence to checkup item, and diagnosis algorithm library is the library function in host computer.
The embodiment of the present invention uses host computer automated software for TestStand (test execution management software),
The test code module that TestStand allows a variety of programming languages to write develops automatic test sequence.Further, this is examined
Disconnected algorithms library can be by Labview (Laboratory Virtualinstrument Engineering Workbench, void
Quasi- instrument development platform) exploitation, when carrying out automated diagnostic, which is desirably integrated into host computer as upper
One library function of position machine.Meanwhile the diagnosis algorithm library meets 14229 diagnostic service agreements.
Fig. 2 show the interaction figure of automated diagnostic method, and when carrying out automated diagnostic, host computer can call above-mentioned
Library function builds automatic test sequence as diagnostic message in advance, and diagnostic message is sent to ECU so that ECU believes the diagnosis
Breath is handled.But ECU can not identify the diagnostic message, and the diagnostic message that will be stored in advance is needed to be converted into message information,
Then according to the corresponding relationship of message information and diagnostic command, diagnostic command is determined, which can be with the lattice of message
Formula is transferred to ECU, and ECU can recognize the diagnostic command.It is understood that the corresponding relationship can be the automatic test sequence
Corresponding relationship between column and message information format.
Diagnostic command is sent to ECU by step S104, so that ECU receives diagnostic command.
In conjunction with Fig. 2, includes host computer and ECU in hardware-in-the-loop test system, be integrated with diagnosis algorithm in host computer
Library simultaneously can build automated diagnostic sequence, and when carrying out automated diagnostic, host computer sends diagnostic command, ECU to ECU
Receive the diagnostic command.
Specifically, according to the content of diagnostic command, host computer can be sent the diagnostic command with the format of multiframe message
To ECU, ECU, the ECU diagnostic command ready to receive sent with message format can also be sent to the format of single frames message.
In order to determine that can ECU normally judge that checkup item, either with or without failure, host computer can also build direct fault location
Sequence, and the direct fault location sequence is sent to ECU, so that ECU receives the direct fault location sequence, ECU can be infused the failure
Enter sequence to be analyzed and handled, if the ECU can judge to be out of order, it is determined that ECU can normally judge to checkup item
Failure.
For example, the voltage value to the hydrostatic sensor that checkup item is automobile, the normal model of the voltage value of the hydrostatic sensor
It encloses for 5V~10V, should be 5V~10V to the normal range (NR) of the voltage value for the hydrostatic sensor that checkup item is automobile, it will be hydraulic
The voltage value of sensor is the direct fault location sequence that 11V is built as host computer, and the direct fault location sequence is sent to ECU,
So that ECU receives the direct fault location sequence, can verify the ECU judge the failure, if ECU can judge the failure, say
Bright ECU can normally judge the voltage value of hydrostatic sensor.
Step S106 receives the diagnostic response message that ECU is returned, and is handled diagnostic response message to obtain diagnosis knot
Fruit.
Specifically, after the diagnostic response message for receiving ECU return, host computer calls diagnosis algorithm library to ring the diagnosis
It answers message to be analyzed and handled, obtains diagnostic result.
It is understood that the version information that the diagnostic result can be the ECU software is either corresponding to checkup item
Error code.For example, there is event in low -velocity electron cooling fan relay if the low -velocity electron cooling fan relay in ECU breaks down
Barrier is used as diagnostic response message, then after host computer is to the diagnostic response message analysis and processing, diagnostic result is and low -velocity electron
The corresponding error code of cooling fan relay；For another example, if the high-velocity electrons cooling fan relay in ECU breaks down, high-velocity electrons wind
Relay is fanned to break down as diagnostic response message, then after host computer is to the diagnostic response message analysis and processing, diagnosis knot
Fruit is error code corresponding with high-velocity electrons cooling fan relay.
Automated diagnostic method provided in this embodiment, by calling diagnosis algorithm library, to the diagnostic message being stored in advance
It is analyzed, obtains diagnostic command, diagnostic command is then sent into ECU, so that ECU receives diagnostic command, then received ECU and return
The diagnostic response message returned handles diagnostic response message to obtain diagnostic result, be realized in hardware-in-the-loop test system
Automated diagnostic functional test is completed on system, is reduced tester's working strength and cost, is improved the accuracy of test result, mention
The efficiency of the repeatability and diagnosis of high Test coverage degree and test, keeps test process more safe and orderly.
