Brief description
Fig. 1 is onboard instruments and external testing host computer annexation schematic diagram in one embodiment of the invention.
Fig. 2 is the flow chart of the onboard instruments parts independent test method in one embodiment of the invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention are more
It is easily readily appreciated by one skilled in the art, thus make apparent defining to protection scope of the present invention.
In order to avoid the test of some redundancies, improve production test equipment development efficiency and product test efficiency, this
Bright carry out on the basis of original instrument, a kind of new onboard instruments method of testing be provided, as it is shown in figure 1, it include multiple firmly
Part parts and the controller controlling multiple hardware component, described controller includes conventional control instruction set unit and test control
Instruction set unit processed, described conventional control instruction set unit is in normal mode according to program or control signal control
Hardware component；For coordinating with host computer in test mode, described testing and control instruction set unit realizes that alone hardware component is surveyed
Examination., make onboard instruments individually can carry out with the outside host computer for test under test conditions independent of meter contact function
Communication, and respond unique specific instruction that host computer sends.
In specific implementation process, hardware component passes through CAN agreement or K wire protocol and host computer communication.
Wherein, above-mentioned hardware component can but be not limited only to include display screen, LED, buzzer, stepper motor, hard
One or more in part input signal and meter key.
Onboard instruments in the present embodiment is combined, and also provides a kind of onboard instruments parts independent test method, such as Fig. 2 institute
Show, including host computer, communication interface, by the communication instruction that formulation is fixing, and communication instruction is sent by CAN or K line
To onboard instruments, it is achieved instrument is mutual with test host computer information.Host computer sends command adapted thereto, and instrument program control is corresponding
Hardware component performs correlation function, and instrument also can feed back to host computer performing result simultaneously, and host computer automatic decision performs
Result.As long as guaranteeing that each class hardware effort is normal, it becomes possible to ensure that meter hardware is qualified.
Concrete method of testing comprises the following steps：
S10. the unique specific bus communication instruction of hardware component distribution to described onboard instruments；This unique specific control
Instruct unrelated with the model of onboard instruments, for it is only for the hardware component of onboard instruments, as long as same Hardware Subdivision
Part, no matter it is arranged on any one onboard instruments, host computer all can by this unique specific control instruction with vehicle-mounted
Instrument communicates.
In the preferred case：S11., before carrying out hardware production detection, whether host computer can go detection communication interface
Conducting, in the case of occurring that communication interface and onboard instruments are disconnected, it will send false alarm；If reminded, perform step
Rapid S12.S12., after determining that communication interface is working properly, host computer is tested automatically.
S20. when the duty carrying out hardware component is tested, host computer by described communication interface to vehicle-mounted
Instrument individually sends unique specific control instruction, is used for controlling one or more hardware componenies in onboard instruments, and this is specific
Control instruction follows CAN agreement or K wire protocol.In order to ensure that onboard instruments is during normal use interference-free, control
System instruction is different from the mailing address when normal use for the onboard instruments and control instruction.
S30. described host computer obtains the feedback states of one or more described hardware component；Obtaining display screen, LED
Lamp, stepper motor feedback states during also use acquisition user to detect the optical device of hardware component, such as optical camera
Head or sensor etc., the method obtaining feedback states includes following sub-step：
S31. the optical states of described hardware component before host computer is obtained by described optical device and sends control instruction；S32. go up
Position machine is obtained the optical states of described hardware component after sending control instruction by described optical device；S33. host computer is by right
Obtain feedback states than the difference of optical states twice.
In addition, when obtaining hardware circuit for checking input signals and meter key, then by testboard bay input difference
Low and high level, pwm signal, resistance signal, host computer sends command adapted thereto, and instrument feeds back testing result, and host computer is according to instead
Feedback result, whether automatic decision meter hardware signal input circuit is qualified.
S40. the contrast according to feedback states i.e. can determine that whether the one or more hardware componenies being communicated are normal.
Further, described communication interface is CAN interface or K line interface.
In order to describe more easily, illustrate with ABS alarm lamp in instrument, the instrument of different depots, ABS alarm lamp
Control logic different, have plenty of and need to judge different rigid line low and high levels or different CAN data.So press
According to traditional detection method, host computer is necessary for, according to the depot's specification corresponding to this instrument, sending corresponding trigger,
Just can light ABS alarm lamp to detect, for the instrument of different depots, light logic different, host computer exploitation will
More complicated and loaded down with trivial details.According to new test thinking, depart from the function of instrument, define a fixing agreement, by CAN or
K line is sent to instrument, and the agreement that for example ABS alarm lamp is lighted in definition is that host computer sends：0x11 0x55 0x23 0x01, that
When host computer sends the data reserved in agreement, instrument just lights ABS alarm lamp.The instrument of different depots, it is fixed all to support
The good agreement of justice, it is possible to promote the development efficiency of test equipment and the testing efficiency of instrument.
Above in conjunction with accompanying drawing, embodiments of the present invention are explained in detail, but the present invention is not limited to above-mentioned enforcement
Mode, in the ken that those of ordinary skill in the art are possessed, can also be on the premise of without departing from present inventive concept
Make a variety of changes.
