In step S1 of FIG.
When it is detected that the vehicle is being stored and the ignition IGN is ON (Y in step S1), the process proceeds to step S2 to display an initial screen, otherwise, the vehicle is being stored in this step S1 and the ignition is turned ON. (N in step S1).

In step S2, the CPU 12
The D driver 14a is controlled to display an initial screen on the LCD 14b, and waits for a predetermined switch operation in steps S3 and S4 or a diagnosis start command from the handy terminal H / T in step S5.

In step S3, when the end switch is pressed, the CPU 12 ends a series of processing (Y in step S3), and otherwise shifts to step S4 (N in step S3). In step S4, the CPU 12
Detects whether the end switch and the A switch (SW-A in the figure) have been pressed for a predetermined time. Here, for example, it is determined that the A switch has been pressed for 2 seconds or more while the end switch has been pressed for 3 seconds. If detected, the process proceeds to step S6 to execute self-diagnosis 1 (Y in step S4), otherwise, the process proceeds to step S5 to wait for a diagnosis start command from the handy terminal H / T (step S4). N).

In step S5, the CPU 12 waits for a diagnosis start command from the handy terminal H / T (N in step S5). If a diagnosis start command is received here (Y in step S5), diagnosis starts in step S7. After returning the permission command to the handy terminal H / T, the process proceeds to step S8 to execute the self-diagnosis 2. In step S8, the self-diagnosis of the diagnosis item according to the diagnosis request of each diagnosis item from the handy terminal is performed, and the result is returned to the handy terminal.
The diagnostic content of each diagnostic item is the same as the individual processing in steps S602 to S613 in FIG. When the self-diagnosis 2 is completed, the process returns to step S1.

On the other hand, in step S6, processing relating to the self-diagnosis 1 as shown in FIG. 4 is performed. This self-diagnosis 1 is to execute a self-diagnosis from the vehicle operation information collection device. When the self-diagnosis 1 is completed, the process returns to step S1.

Next, referring to FIG. 4, a description will be given of an example of processing when the self-diagnosis 1 is executed from the vehicle operation information collecting device corresponding to step S6. FIG. 4 is a flowchart illustrating a processing example in a case where self-diagnosis is executed from the vehicle operation information collection device.

In step S601, the CPU 12 controls the buzzer BZ to notify the start of the self-diagnosis, outputs the buzzer sound three times, and shifts the processing to the self-diagnosis processing including the respective diagnosis items in steps S602 to S614. I do.

In step S602, display diagnosis is performed. Here, the CPU 12 performs a test display of digital numbers, a colon, a period, and a symbol mark on the LCD 14b sequentially, or performs a test display of the OK, ALM, and CARD LEDs sequentially. Then, when these test displays are completed, the process moves to step S603.

In step S603, switch diagnosis is performed. Here, the CPU 12 causes a corresponding result to be displayed on the LCD 14b every time each switch is pressed, and the operator displays OK (normal) or NG according to the result display.
(Abnormal) judgment. Then, for example, when the changeover switch is pressed, the process proceeds to step S604.

In step S604, an ignition diagnosis is performed. Here, the CPU 12 determines based on the fact that the ignition switch has been turned ON / OFF.
A corresponding result is displayed on the LCD 14b, and the operator determines OK (normal) or NG (abnormal) based on the result display. Further, for example, if no result is displayed within a predetermined time, the CPU 12 sounds the buzzer BZ to warn of an abnormality. Then, if the diagnosis result is OK, the process automatically proceeds to step S605 if the diagnosis result is NG, for example, by pressing a changeover switch.

In step S605, a speed pulse diagnosis is performed. Here, the CPU 12 controls the LCD based on the speed pulse supplied from the speed sensor 201.
A corresponding speed display is made on 14b, and the operator judges OK (normal) or NG (abnormal) based on the result display. Then, for example, when the changeover switch is pressed, the process proceeds to step S606.

In step S606, an engine rotation pulse diagnosis is performed. Here, the CPU 12 displays the corresponding engine rotation speed on the LCD 14b based on the engine rotation pulse supplied from the engine rotation sensor 211, and the operator determines OK (normal) or NG (abnormal) based on the result display. do. Then, for example, when the changeover switch is pressed, the process proceeds to step S607.

In step S607, analog channel diagnosis is performed. Here, the CPU 12 displays the corresponding temperature on the LCD 14b based on a temperature detection signal supplied from, for example, a temperature sensor connected to the analog CH I / F 22, and the operator displays OK (normal) based on the result display. Alternatively, NG (abnormal) is determined. When there are a plurality of channels, the diagnosis is sequentially performed by operating the changeover switch.
Move to 8.

In step S608, external channel diagnosis is performed. Here, the CPU 12 is connected to the external CH
For example, based on the brake operation of the brake device connected to the I / F 23, a corresponding code is displayed on the LCD 14b, and the operator can confirm that the code is OK (normal).
Alternatively, NG (abnormal) is determined. When there are a plurality of external channels, diagnosis is sequentially performed by operating the changeover switch, and when all the channels are completed, the process proceeds to steps S609 and S610.

In steps S609 and S610, a GPS connection diagnosis and a radio clock connection diagnosis are performed. Here, the CPU 12 is connected to the GP
It is determined whether or not predetermined GPS data and time information can be received from the S device. For example, if accurate data can be received within 4 seconds, OK is displayed on the LCD 14b. If not, NG is displayed and the buzzer BZ is displayed. Sounds for a predetermined time to warn of abnormality. Then, when the diagnosis result is OK, automatically, and when the diagnosis result is NG, for example, by pressing a changeover switch, the process proceeds to step S611.

As described above, when the diagnosis result is normal, the process automatically shifts to the next diagnosis item, and when the diagnosis result is abnormal, the sound is emitted and the shift to the next diagnosis item is temporarily stopped. Then, the temporarily stopped diagnostic item is switched by operating the changeover switch. Therefore, if the diagnosis result is normal, the diagnosis proceeds sequentially, so that the diagnosis is performed efficiently and in a short time. If the diagnosis is abnormal, the diagnosis is performed and stopped temporarily, so that the cause inspection and repair can be surely performed. Become like Such processing corresponds to the transition control means and the diagnostic item switching means in claim 2.

In step S611, a handy terminal diagnosis is performed. Here, the CPU 12 diagnoses the communication terminal and the connection terminal of the handy terminal H / T connected to the handy terminal I / F17. For example, the CPU 12 sends a check command to the handy terminal H / T. If a normal response signal is returned within a predetermined time, OK is displayed on the LCD 14b. Sounds for an hour and alerts you of any abnormalities. Then, when the diagnosis result is OK, automatically, and when the diagnosis result is NG, for example, by pressing a changeover switch, the process proceeds to step S612.

In step S612, an option unit diagnosis is performed. In this case, the CPU 12
A check command is transmitted to an external device connected to the UI 19, and if a normal response signal is returned within a predetermined time, OK is displayed on the LCD 14b. The BZ is sounded for a predetermined time to alert an abnormality. Then, when the diagnosis result is OK, automatically, and when the diagnosis result is NG, for example, by pressing a changeover switch, the process proceeds to step S613 and step S614.

In steps S613 and S614, the CPU 12 displays, for example, “EN” on the LCD 14b to indicate that a series of self-diagnosis processing has been completed.
A message indicating the end of "D" etc. is displayed,
The buzzer BZ is sounded together with the buzzer BZ for a predetermined time to notify the end of the diagnosis. Then, the process proceeds to step S615.

In step S615, the CPU 12
Waits for depression of the changeover switch (N in step S615), and if there is depression (Y in S615), the series of processes of the self-diagnosis 1 is terminated and the process returns.

As described above, according to the above-described embodiment, the start command switch (both switches in step S4 are equivalent).
Each diagnosis item is executed in response to the start command by the following.
The diagnostic result is displayed on the diagnostic result display means (LCD driver 1).
5a and the LCD 15b correspond to this). Therefore, self-diagnosis can be performed by the vehicle operation information collecting device itself without connecting a printer or the like having a diagnostic function as in the related art. As a result, diagnosis of the vehicle operation information collection device can be performed very efficiently. Note that the processing of steps S602 to S612 corresponds to the diagnosis executing means of claim 1.

Further, an example of processing when the self-diagnosis 2 is executed from the handy terminal will be described with reference to FIGS. FIG. 5 is a flowchart illustrating a processing example on the handy terminal side when performing self-diagnosis from the handy terminal. FIG. 8 is an explanatory diagram illustrating an example of a menu screen when a diagnosis item is selected.

In step S801 in FIG. 5, when the self-diagnosis is executed from the handy terminal, the HC which is the CPU of the handy terminal H / T is responded to a predetermined switch operation on the handy terminal H / T.
