Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an inspection apparatus and an inspection system for an in-vehicle information transmission / reception system including a plurality of communication devices.
[0002]
[Prior art]
Communication devices installed in recent automobiles include automobile mobile phones, VICS receivers, ETC in-vehicle devices, and the like. These communication devices operate independently. For example, the communication data of the VICS communication device and the communication data of the ETC in-vehicle device are not supplemented to form complete data.
[0003]
[Problems to be solved by the invention]
By the way, recently, a large amount of data is communicated by connecting a vehicle to the Internet, driving data is exchanged between vehicles for safe driving of vehicles, and information is sent from person to vehicle. It is considered. In such a system, a plurality of communication devices are used, and communication performed by one communication device with the outside is performed by another communication device, or information is simultaneously transmitted and received from a plurality of communication devices. It will be necessary to grasp the situation around.
[0004]
For example, when a car phone is connected to an in-vehicle information transmission / reception system and information is acquired via the Internet, if the mobile phone is out of the communication area, the connection is changed to another communication device to receive information from the Internet. It is necessary to continue.
In addition, it is possible to recognize vehicles around the vehicle through inter-vehicle communication, or to detect people walking in the front or people hiding in the front vehicle by acquiring position information from a mobile phone carried by a person. When constructing a simple driving support system, it is necessary to allow a plurality of communication devices to communicate with the outside at the same time.
[0005]
For this reason, in an in-vehicle information transmission / reception system, it is important that a plurality of communication devices operate according to specifications regardless of the environment. When such a communication device for an in-vehicle information transmission / reception system is mounted on a vehicle, if a user has a mobile phone as a car phone or uses a DSRC in-vehicle device retrofitted, the communication is currently performed. Since it cannot be inspected in advance whether normal communication is performed using a device, normal communication operation cannot be guaranteed.
[0006]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an in-vehicle information transmission / reception system that can inspect whether a communication device is retrofitted or whether the attached communication device operates normally. An inspection apparatus and an inspection system are provided.
[0007]
[Means for Solving the Problems]
The present invention allows the inspection device to perform the same operation as the communication device to be newly installed, operates the already-installed communication device while communicating with the outside by this inspection device, and also installs the already-installed communication device one by one. Since the communication with the inspection device is performed while operating and the influence on the communication of the inspection device by the already installed communication device is inspected, the communication device to be newly installed receives a failure from the already installed communication device and malfunctions. It is possible to inspect whether or not this occurs.
[0008]
In the present invention, the operation program for causing the inspection apparatus to perform an operation equivalent to that of a communication device to be newly installed can be configured to be acquired by communication with the outside. In this way, it is not necessary to store various operation programs in the inspection apparatus.
[0009]
In addition, it is possible to execute an operation of outputting a signal from the information processing device to each device and returning a response signal from each device to the information processing device, and inspecting whether there is a response signal from each device to the information processing device. Thus, it can be configured to determine whether the connection between the information processing apparatus and each device is successful.
Further, when the communication device is incorporated into the vehicle information transmission / reception system, if the communication device has a defect, the communication device individual information and the defect information can be transmitted to the communication device manufacturer. it can.

[0026]
Next, the contents of inspection by the inspection device 29 will be described in order with reference to the display screen of the display 35 in FIG. 5 and the flowcharts shown in FIGS.
When the power of the inspection device 29 is turned on, the inspection selection screen shown in FIG. That is, the inspection device 29 can execute three types of inspections, that is, individual device inspection, device mounting inspection, and application operation inspection, and a desired inspection is selected on this screen.
[0027]
Here, the individual device inspection is a content for inspecting whether or not the communication device is normally operated before mounting the communication device on the vehicle. The device mounting inspection is for inspecting whether or not the communication device operates normally in a state where the device is mounted on the vehicle. The application operation inspection is for inspecting whether a desired communication device performs communication operation without interfering with other communication devices in a state where a plurality of communication devices are mounted on the vehicle. In the following, description will be given separately for each case.
[0028]
(1) Individual device inspection (flow chart in FIG. 6)
When the inspection device 29 is connected to a communication device (referred to as an individual inspection target device) to be inspected and the inspection device 29 is turned on, the inspection selection screen of FIG. Then, select the device individual inspection software on the screen. Then, power is supplied to the inspection target device (step S1 in FIG. 6). The device to be inspected is initialized when the power is turned on. When the initial setting is completed, the device ID, the initial setting completion notification, the command set information, and the data dictionary ID are transmitted to the inspection device 29.
[0029]
As shown in FIG. 5B, the inspection device 29 displays the name and model number of the inspection target device on the display 35 based on the transmission information from the inspection target device, and then displays the inspection screen in FIG. 5C. Switch. At this time, if the model number of the inspection target device is not displayed on the display 35, a driver for operating the inspection target device is installed in the inspection device 29, or “device” is displayed on the screen of FIG. “Data setting” is selected, and various data of the inspection target device are input to the inspection device 29 on the screen of FIG.
[0030]
Here, the command set is a command set that can be accepted by the inspection target device. This instruction set is necessary according to the operation of the inspection target device from the standard instruction set database that defines the instruction set of the inspection target device when the specification of how the inspection target device operates is determined. Selected from instructions. The contents of this instruction set database are classified into basic instructions and application instructions that can be customized as appropriate according to how the device to be inspected is used. If the device to be inspected receives only the basic function, it is only necessary to transmit the ID of the basic instruction set defined in the instruction set database to the inspection device 29. Software using the basic function instruction set can package the instruction set program, which facilitates software development (in order to develop software, it is only necessary to define data to be used). If the data to be used is standard, the function of the device in which the instruction set and the data set are packaged can be integrated into one chip. Alternatively, the operating environment can be configured by downloading an instruction set and a data set from the outside using programmable logic.
[0031]
When the information such as the initial setting completion notification is not received from the inspection target device, the inspection device 29 resets the power supply of the inspection target device and receives information such as the initial setting completion notification from the inspection target device. wait. When this power reset is performed a predetermined number of times (“NO” in step S2, “NO” in step S3 and step S4), and no information is received from the target device (“YES” in step S4), an inspection is performed. The device 29 stores the startup error in the RAM 40 (step S5), ends the power supply to the inspection target device (step S19), and ends the individual device inspection.
[0032]
When information such as an initial setting completion notification is received from the inspection target device (“YES” in step S2), the inspection device 29 sets the received data dictionary (DD) (step S6), and among many commands One command is selected and transmitted to the inspection target device (step S7).
[0033]
When receiving the command, the inspection target device transmits data in response to the command. Upon receiving a response to the command, the inspection device 29 checks the received response data, and if the check result is good, transmits the next command to the inspection target device (“YES” in step S8, step S9). ("YES" in step S10, "NO" in step S11, repeat step S12). When the check is an error (“NO” in step S10), the error is recorded (step S13), and the process proceeds to a step of transmitting the next command to the inspection target device.
[0034]
If the response is not received after transmitting the command, the inspection device 29 transmits the command again and waits for information such as an initial setting completion notification from the inspection target device. This power reset is performed a predetermined number of times ("NO" in step S8, "NO" in steps S14 and S15), and if no response data is transmitted from the target device ("YES" in step S15)), an inspection is performed. The device 29 stores the response error in the RAM 40 (step S16), and proceeds to the step of transmitting the next command.
[0035]
When the response data is checked for all commands (“YES” in step S11), the inspection device 29 transmits a completion notification to the inspection target device (step S17). Then, when a response to the completion notification is received from the inspection target device (step S18), the inspection device 29 stops the power supply to the inspection target device (step S19) and ends the individual device inspection. After the inspection is completed, for the communication device having a defect, the inspection device 29 is connected to the manufacturing company server 44 via the Internet 26, and the ID (individual information) and the defect information of the communication device are transmitted.
[0036]
(2) Equipment mounting inspection (flow charts of FIGS. 7 and 8)
When the inspection device 29 is connected to the communication interface 15 of the in-vehicle server 2 and the inspection device 29 is turned on, the screen shown in FIG. 5A is displayed. Here, the on-board inspection software is selected. Then, the in-vehicle server 2 and the inspection device 29 communicate with each other (step A1), and thereby the in-vehicle server 2 activates a device connection program installed in itself. This device connection program is for checking the connection status between the signal line and the power supply line between the in-vehicle server 2 and the devices connected to the in-vehicle server 2, and the in-vehicle server 2 includes the communication devices 16-23. And determines whether the connection between the information server 2 and each of the communication devices 16 to 23 is successful (connection determination means). The determination result is displayed on the display 35 of the inspection apparatus 29 as shown in FIG. 9 (step A2). On this connection check screen, a confirmation button is displayed for each connection part. By operating this confirmation button, input is made to confirm that the devices are correctly connected and that the power supply is also correctly connected. (Step A3).
[0037]
When there is an input for connection confirmation (“YES” in step A3), the inspection device 29 can select one of the communication devices connected to the communication interface 15 as the inspection target device and communicate with the device. Therefore, the port of the inspection target device on the communication interface 15 is set, and power is supplied to the inspection target device (steps A4 and A5).
[0038]
Next, the inspection device 29 communicates with the inspection target device under default communication conditions, and acquires a driver and communication software from the inspection target device (step A6). Drivers and communication software may be installed by an inspector. The inspection target device that has transmitted the driver and the communication software thereafter transmits the device ID, command set information, and data dictionary ID.
[0039]
When the information such as the initial setting completion notification is not received from the inspection target device, the inspection device 29 resets the power supply of the inspection target device and receives information such as the initial setting completion notification from the inspection target device. wait. This power reset is performed a predetermined number of times (“NO” in step A7, “NO” in step A20 and step A21), and if no information is received from the target device (“YES” in step A21), the inspection is performed. The device 29 stores the activation error in the RAM 40 (step A22), and proceeds to the inspection of the next inspection target device (step A17).
[0040]
When information such as an initial setting completion notification is received from the inspection target device (“YES” in step A7), the inspection device 29 sets the received data dictionary (DD) (step A8), and a number of inspection items. One inspection item is selected from the inside, and the inspection command is transmitted to the inspection target device (step A9, step A10).
[0041]
When receiving the inspection command, the inspection target device transmits data in response to the inspection command (step A10). When a response to the inspection command is received (“YES” in step A11), the inspection device 29 checks the received response data (step A12), and if the check result is good (“YES” in step A13). Then, the fact that the check of the one inspection item is completed is transmitted (step A14), and when a response from the inspection target device is received (step A15), it is then determined whether or not all the inspection items are completed (step A15). A16). If the result of checking the response data is not good ("NO" in step A13), an error is recorded (step A17), and the process proceeds to step A16 to determine whether all inspection items have been completed. To do.
[0042]
In addition, after transmitting the inspection command, if the data in response to the inspection command is not received (“NO” in step A11), the inspection device 29 retransmits the same inspection command and the data in response thereto is sent. It is determined whether or not it has been received (“NO” at step A24 and step A25, step A10, step A11). If the response data is not received even after repeating this operation a predetermined number of times, a list of inspection items is displayed on the display 35 to indicate that the process proceeds to the next inspection item ("YES" in step A25, step A26).
[0043]
When there is an operation for accepting the transition to the next inspection item (“YES” in step A27), or when a predetermined time has passed without the operation (“NO” in step A27, “YES” in step A28) ]), The inspection device 29 stores the error of the current inspection item and skips the current inspection item (step A29).
[0044]
Then, a command for the next inspection item is transmitted to the inspection target device (“NO” in step A16, step A30, step A10), and thereafter, the same operation as described above is executed for each inspection item. When the check is completed for all inspection items for one inspection target device (“YES” in step A16), the inspection device 29 determines whether there is an uninspected communication device, and if there is one (step In step A17, "NO"), the power supply to the inspection-finished device is cut off, and the same operation as described above is executed for all inspection items for one of the untested communication devices (step A31 to step A4). To).
[0045]
When there is no unexamined communication device (“NO” in step A17), the inspection device 29 stops supplying power to the communication device that has been inspected (step A18), and displays the inspection result on the display 35. (Step A19), the individual mounting inspection is terminated. After the inspection is completed, for the communication device having a defect, the inspection device 29 is connected to the manufacturing company server 44 via the Internet 26, and the ID (individual information) and the defect information of the communication device are transmitted.
[0046]
(3) Application operation inspection (flow charts of FIGS. 10 to 13)
In this application operation inspection, in the system configuration shown in FIG. 1, the mobile phone 20 is not yet installed, but this time the mobile phone 20 is newly installed, and the other communication devices 16-19 and 21-23 are Assume that it is already installed. It is assumed that the owner of the vehicle desires a model of the cellular phone 20 to be mounted, but has not purchased the actual product.
[0047]
When this inspection is performed, first, a driver and communication software (hereinafter referred to as operation software) of the mobile phone 20 (retrofitted communication device) desired to be installed in the inspection apparatus 29 are downloaded. This download is done as follows. That is, the mobile phone communication software stored in the ROM 39 is downloaded to the programmable logic unit 31 to cause the programmable logic unit 31 to function as a mobile phone. Then, the programmable logic unit 31 is connected to the information server 43 via the Internet 26, and the operation software for the mobile phone 20 desired to be installed is downloaded from the information server 43 (step B1).
[0048]
Next, when the inspection device 29 is connected to the communication interface 15 of the in-vehicle server 2 and the inspection device 29 is turned on, the screen of FIG. 5A is displayed. Here, the application operation inspection software is selected. Then, first, an inspection similar to the above-described device mounting inspection is performed (step B2). And the inspection apparatus 29 memorize | stores the use conditions of the communication apparatus which responded in step B3 while memorize | storing ID of the already mounted communication apparatus which responded in the test | inspection of step B2 (step B4), The already mounted devices are classified according to the use conditions (step B5). Here, the use condition of the already-installed communication device indicates whether the vehicle is used while parked or stopped, or used while the vehicle is running. The standard-equipped communication device 16, first and second The wireless LAN communication devices 17 and 18 and the DSRC communication device 19 are used when parked and stopped, and the front and rear inter-vehicle communication devices 21 and 22 and the ETC in-vehicle device 23 are used during traveling.
[0049]
Next, the inspection device 29 starts an individual interference inspection at the time of parking and stopping. This individual interference inspection at the time of parking / stopping is performed as a mobile phone 20 to be retrofitted by the downloaded operation software by the programmable logic unit 31 of the inspection device 29 and communicates with the outside (step B6), and the existing interference / parking use is already performed. One communication device is selected from the mounted devices, and the communication device is operated to communicate with the outside (step B7).
[0050]
A specific example of the contents of the interference inspection will be described. For example, the inspection device 29 is connected to the information server 43 via the Internet, and the data created for inspection (inspection data) is downloaded while the vehicle is parked. A single communication device is activated. Then, by using predetermined inspection data, it is possible to check whether there is interference between the mobile phone replaced by the inspection device 29 and the already installed communication device depending on whether the download time is short or whether the downloaded data is correct or not. Judgment can be made.
[0051]
The inspection device 29 determines the presence or absence of interference based on the result of the interference inspection (step B8). When there is no interference (“NO” in step B8), the inspection device 29 stores the inspection condition and the inspection result ( Step B9), the next communication device used for parking and stopping is selected and the same interference inspection is performed ("NO" in step B10, and the process proceeds to step B8 in step B11).
[0052]
If there is interference (“YES” in step B8), the inspection device 29 stores the ID and interference status of the selected communication device in the RAM 40 (step B12), and selects the next communication device to be used when parked or stopped. A similar interference test is performed. Such interference inspection is carried out one by one for the already mounted equipment used at the time of parking and stopping, and when the inspection of all the already mounted equipment used at the time of parking is completed, the individual interference inspection at the time of parking is terminated (in step B10). "YES").
[0053]
When the individual interference inspection at the time of parking and stopping is completed, a display asking whether or not to shift to the next inspection is displayed on the display 35 of the inspection device 29 (step B13). When an operation for shifting to the next inspection is performed based on this display, the combined inspection at parking and stopping is started (“YES” in step B14). If it is not desired to shift to the next inspection, it can be left as it is. Then, when a certain time has elapsed, the inspection device 29 performs an inspection end process, stops the communication device in operation, and displays the inspection result on its own display 35 (“NO” in step B14, step B15). "YES", step B16), the application operation inspection is terminated.
[0054]
When the inspection apparatus 29 starts the combined interference inspection at the time of parking and stopping, it operates the programmable logic unit 31 of the inspection apparatus 29 as the mobile phone 20 and communicates with the outside (step B17), while the installed equipment used at the time of parking and stopping is checked. Two communication devices are selected from among them and the communication devices are operated (step B18).
[0055]
The contents of the interference inspection are, for example, operating two communication devices used during parking while connecting the inspection device 29 to the information server 43 via the Internet and downloading the inspection data. Then, the presence or absence of interference between the mobile phone replaced by the inspection device 29 and the two installed communication devices is determined based on the length of the download time of the inspection data, or whether the downloaded data is correct.
[0056]
The inspection device 29 determines the presence or absence of interference based on the result of the interference inspection (step B19), and if there is no interference (“NO” in step B19), the inspection condition and result are stored in the RAM 40 (step B20). ). If there is interference (“YES” in step B19), the inspection apparatus 29 stores the ID and interference status of the selected communication device in the RAM 40 (step B23). In this way, the inspection of interference with the mobile phone (inspection device 29) is carried out with two already installed communication devices used at the time of parking and stopping as a set until there is no new combination of two units ("NO" in step B21). ”, The process proceeds to step B19 in step B22). When all the combinations of the two units are completed, the combined interference inspection at the time of parking and stopping is terminated (“YES” in step B21).
[0057]
Thereafter, it is selected whether or not to proceed to the next inspection. If no operation is performed, the application operation inspection can be ended here ("NO" in step B25, "YES" in step B26, step B27). When it is selected to shift to the next inspection (“YES” in step B25), the inspection device 29 starts the traveling individual interference inspection. In this individual interference inspection during traveling, the programmable logic unit 31 of the inspection device 29 is operated as the mobile phone 20 to communicate with the outside (step B28), and one communication device is selected from the already installed devices used during traveling. The communication device is selected and operated (step B29). The details of the inspection are the same as the individual interference inspection at the time of parking and stopping.
[0058]
The inspection device 29 determines the presence or absence of interference based on the result of the interference inspection (step B30), and if there is no interference (“NO” in step B30), the inspection condition and result are stored in the RAM 40 (step B31). ). If there is interference (“YES” in step B30), the inspection apparatus 29 stores the ID and interference status of the selected communication device in the RAM 40 (step B34).
[0059]
Thereafter, the next communication device used during traveling is selected and the same interference test is performed (“NO” in step B32, step B33). Such interference inspection is carried out one by one for the already mounted devices used during traveling, and when all the already mounted devices used for parking and stopping have been inspected ("YES" in step B32), individual End interference inspection.
[0060]
When the traveling individual interference inspection is completed, it is selected whether or not to proceed to the next inspection (step B35, step B36). When it is selected to shift to the next inspection (“YES” in step B36), the inspection device 29 starts the traveling-time complex interference inspection. In this complex interference inspection during traveling, the programmable logic unit 31 of the inspection device 29 is operated as the mobile phone 20 to communicate with the outside (step B39), and two communication devices among the already installed devices used during traveling are connected. The communication apparatus is selected and operated (step B40). The details of the inspection are the same as those in the combined interference inspection during parking and stopping.
[0061]
The inspection device 29 determines the presence or absence of interference based on the result of the interference inspection, and if there is no interference (“NO” in step B41), the inspection device 29 stores the inspection condition and result in the RAM 40 (step B42). When there is interference (“YES” in step B41), the inspection device 29 stores the ID and interference status of the selected communication device in the RAM 40 (step B45). In this way, the inspection of interference with the mobile phone (inspection apparatus 29) is performed until two sets of already-installed communication devices used at the time of parking and stopping are used (“NO” in step B43). ”, The process proceeds to step B41 in step B44). When all the combinations of the two units are completed, the parking / interlocking combined interference inspection is terminated (“YES” in step B43), and the application operation inspection is terminated.
[0062]
After the inspection is completed, for the communication device having a defect, the inspection device 29 is connected to the manufacturing company server 44 via the Internet 26, and the ID (individual information) and the defect information of the communication device are transmitted.
[0063]
As described above, according to the present embodiment, since the inspection device 29 functions in the same manner as the retrofit communication device, the installed communication devices are operated one by one to perform the interference inspection, so that the retrofit communication device is a reality. Even if it is not, it is possible to inspect whether or not interference occurs between the retrofit communication device and the existing communication device when it is actually attached to the vehicle.
[0064]
In this embodiment, two communication devices used at the time of parking and stopping are combined to determine whether interference occurs between them and a retrofit communication device. Also, two communication devices used at the time of traveling are combined in units of two. Therefore, it is possible to more reliably inspect the presence or absence of interference between the retrofit communication device and the existing communication device.
[0065]
In addition, for a communication device that has failed due to the inspection, the contents of the failure are transmitted to the manufacturing company, which can be used when upgrading the product version.
[0066]
The present invention is not limited to the embodiments described above and shown in the drawings, and can be expanded or changed as follows.
The inspection by the inspection device 29 is not limited to the case where there is no post-installation communication device, and after the post-installation communication device is attached to the vehicle, before the delivery to the user, the post-installation communication device and the pre-installation communication device It can be used when inspecting the presence or absence of interference.
The inspection device 29 is not limited to a portable type.
When performing an interference test between a retrofitted communication device and an existing communication device, check the interference between the retrofitted communication device and all the existing communication devices, Interference inspections with all communication devices used when the vehicle is stopped and interference inspections with all the communication devices used during travel among the installed communication devices and the installed communication devices. You may make it perform an interference test | inspection with one each of the already mounted communication apparatus.
