Next, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic configuration block diagram of a main part of the in-vehicle device of the embodiment.
The in-vehicle device 10 includes an MPU 11 that controls the entire in-vehicle device 10, a display panel 12 that displays various information, a sub MPU 13 that performs drive control of the display panel 12 under the control of the MPU 11, and operations that perform various operations. A motor driver 15 that generates a drive signal to control the attitude of the display panel 12 under the control of the unit 14 and the sub MPU 13, and a motor that actually drives the display panel 12 based on the drive signal output from the motor driver 15 16, a card slot 17 into which a card-type device CRD such as a memory card is inserted, and a card interface (I / F) 18 that performs an interface operation of the card slot 17.

Here, connected to the MPU 11 are a ROM 21 that stores a control program and control data in advance, a RAM 22 that temporarily stores various data, and an EEPROM 23 that stores various data in a nonvolatile manner so as to be updatable. In addition, a CPU (not shown) that performs various controls based on a control program stored in the ROM 21 is provided.
The display panel 12 includes, for example, a liquid crystal display, and a touch panel that constitutes a part of the operation unit 14 is provided on the surface of the display panel 12 as necessary.

  The sub MPU 13 performs various controls based on a ROM (not shown) that stores a control program and control data in advance, a RAM (not shown) that temporarily stores various data, and a control program stored in the ROM. And a CPU (not shown). The sub MPU 13 further includes a first insertion detection switch (SW) 24 for detecting that the card type device CRD is inserted into the card slot 17 and that the card type device CRD is completely installed in the card slot 17. A second insertion detection switch (SW) 25 for detection is connected.

FIG. 2 is an explanatory diagram of an installation state of the in-vehicle device. FIG. 3 is an external perspective view of the in-vehicle device in a normal use state. FIG. 4 is an external perspective view of the card slot operating state of the in-vehicle device.
The in-vehicle device 10 is provided so that the housing 10A is accommodated in the dashboard panel DP.
The operation unit 14 instructs the display panel 12 to change from the normal use state (closed state) of the display as shown in FIG. 3 to the open state where the card slot 17 can be operated as shown in FIG. And a close key 20 for giving an instruction to change the posture of the display panel 12 from the open position to the normal use state (closed state).

Above the side surface of the display panel 12, as shown in FIG. 2, there is provided a sliding shaft 12A that slides in a sliding groove 10B provided on the opposing surface of the housing 10A. Further, below the side surface of the display panel 12, there is provided a rotation shaft 12B that is rotatably supported by a slide bar 16A that is driven by the motor 16 in the directions of arrows F and R.
As a result, when the slide bar 16A is driven in the direction of arrow F by the motor 16, the display panel 12 falls in the clockwise direction in FIG. 2, and the slide shaft 12A slides downward in the slide groove 10B. As shown in FIG. 4, the user can operate the card slot 17 or the like (open state).

  On the other hand, when the slide bar 16A is driven in the arrow R direction by the motor 16, the display panel 12 rises counterclockwise in FIG. 2, and the slide shaft 12A slides upward in the slide groove 10B. Then, as shown in FIG. 3, a normal use state (closed state) is obtained.

Next, the operation of the in-vehicle device according to the embodiment will be described.
First, the MPU 11 detects the state of the first insertion detection switch 24 (step S11).
Next, the MPU 11 determines whether or not the card-type device CRD has been inserted based on the state of the first insertion detection switch 24 (step S12).
If the card type device CRD is not inserted in the card slot 17 in the determination in step S12 (step S12; No), the MPU 11 permits the sub-MPU 13 to put the display panel 12 into a normal use state. Therefore, a close permission command is issued (step S19).

As a result, when the close key 20 is operated by the user, the sub MPU 13 drives the slide bar 16 </ b> A in the direction of arrow R by the motor 16 via the motor driver 15. As a result, the display panel 12 rises counterclockwise in FIG. 2, and the sliding shaft 12A slides upward in the sliding groove 10B. As shown in FIG. State).
When the card type device CRD (length L) is inserted into the card slot 17 in the determination in step S12 (step S12; Yes), the MPU 11 detects the state of the second insertion detection switch 25 (step S13). ).

Next, the MPU 11 determines whether or not the card-type device CRD is completely inserted into the card slot 17 based on the state of the second insertion detection switch 25, that is, the card slot 17 while the card-type device CRD is usable. It is discriminated whether or not it is mounted inside (step S14).
If it is determined in step S14 that the card type device CRD is not completely inserted into the card slot 17, that is, if the card type device CRD is usable and not installed in the card slot 17 (step S14). S14; No), the process proceeds to step S12 again, and the same process is performed thereafter.

  In step S14, whether or not the card-type device CRD is completely inserted into the card slot 17, that is, if the card-type device CRD is inserted in the card slot 17 in a usable state (step S14). S14; Yes), the MPU 11 makes an inquiry to the card-type device CRD mounted via the card I / F 18 to determine the type of the card-type device CRD (step S15).

  Subsequently, with reference to the card information database in the ROM 21 or the EEPROM 23, the attitude (slope angle) data of the display panel 12 corresponding to the card type device CRD is searched (step S16).

Next, the MPU 11 determines whether or not the attitude data of the display panel 12 corresponding to the card type device CRD exists in the card information database in the ROM 21 (or the EEPROM 23) (step S17).
If it is determined in step S17 that the posture information of the display panel 12 corresponding to the card type device CRD exists in the card information database in the ROM 21 (or further the EEPROM 23) (step S17; Yes), based on the posture data. Then, it is determined whether or not the card-type device CRD is likely to interfere with the display panel 12 which is a movable part (step S18).

If it is determined in step S18 that the attached card-type device CRD is not likely to interfere with the display panel 12 (step S18; No), the MPU 11 sets the display panel 12 in a normal use state with respect to the sub MPU 13. In order to permit this, a close permission command is issued (step S19).
As a result, when the close key 20 is operated by the user, the sub MPU 13 drives the slide bar 16 </ b> A in the direction of arrow R by the motor 16 via the motor driver 15. As a result, the display panel 12 rises counterclockwise in FIG. 2, and the sliding shaft 12A slides upward in the sliding groove 10B. As shown in FIG. 3 and FIG. The state (closed state) is entered, and the card-type device CRD is housed on the back side of the display panel 12.

If it is determined in step S18 that the attached card type device CRD may interfere with the display panel (step S18; Yes), is the card type device CRD capable of avoiding interference by adjusting the angle of the display panel 12? It is determined whether or not (step S20).
If it is determined in step S20 that a card-type device CRD capable of avoiding interference by adjusting the slope angle of the display panel 12 is mounted (step S20; Yes), the MPU 11 cards the display panel 12 to the sub MPU 13. A conditional close permission command is issued to allow a position laid down from the normal use state by a predetermined slope angle based on the maximum close position CMAX included in the posture data registered in the information database to be closed. (Step S21).

  As a result, when the user operates the close key 20, the sub MPU 13 drives the slide bar 16 </ b> A in the arrow R direction by the motor 16 via the motor driver 15. As a result, the display panel 12 rises counterclockwise in FIG. 2, and the sliding shaft 12A slides upward in the sliding groove 10B. As shown in FIGS. The position that does not interfere with the device CRD1 is set to the maximum closed position CMAX, and the closed state is entered. Here, the length L1 of the card-type device CRD1 is longer than the length L of the card-type device CRD shown in FIG.

  If it is determined in step S20 that a card-type device CRD that cannot avoid interference by adjusting the slope angle of the display panel 12 is mounted (step S20; No), the MPU 11 moves the display panel 12 to the sub MPU 13. In order to prohibit the close state, issue a close prohibit command. As a result, the operation of the close key 20 is ignored until the card type device CRD is removed by the MPU 11.

If it is determined in step S17 that the posture information of the display panel 12 corresponding to the card type device CRD does not exist in the card information database (step S17; No), it is determined whether or not the user's manual closing operation has been performed. (Step S23).
That is, the fact that the attitude data of the display panel 12 corresponding to the card type device CRD does not exist in the card information database means that the card type device CRD is newly installed. It is appropriate to treat the card type device CRD that cannot avoid interference as if it is mounted. However, since it is considered that the user is performing a manual closing operation based on the actual card-type device CRD mounted state, when the user manually performs the closing operation, the state after the closing operation is maximum closed. This is because the position CMAX is handled.

  Here, as the manual closing operation, for example, when it is determined that the attitude data of the display panel 12 corresponding to the card type device CRD does not exist in the card information database, and the close key 20 is operated, Instead of closing the display panel 12 at once, it is possible to increase the predetermined slope angle, for example, 5 ° by a single operation of the close key 20, and to obtain a desired slope angle by a plurality of operations. It is done. Of course, it is also possible to increase the predetermined slope angle and perform the operation in the same manner by performing a long press operation of the close key 20.

If the user's manual closing operation is performed in step S23 (step S23; Yes), the card information database in the EEPROM 23 is used with the final closing position as the posture data corresponding to the card type device CRD. Is stored (registered) (step S24).
Subsequently, the MPU 11 permits the sub MPU 13 to close the position laid down from the normal use state by a predetermined slope angle based on the maximum close position CMAX included in the posture data registered in step S24. Therefore, a conditional close permission command is issued (step S21).

As a result, when the close key 20 is operated by the user, the sub MPU 13 drives the slide bar 16 </ b> A in the direction of arrow R by the motor 16 via the motor driver 15. As a result, the display panel 12 rises counterclockwise in FIG. 2, and the sliding shaft 12A slides upward in the sliding groove 10B. As shown in FIGS. The position that does not interfere with the mold device CRD1 is set to the maximum closed position CMAX, and the closed state is entered.
If it is determined in step S23 that the user's manual closing operation has not been performed (step S23; No), the MPU 11 is mounted with a card-type device CRD that cannot avoid interference even by adjusting the angle of the display panel 12. The close prohibit command is issued to the sub MPU 13 to prohibit the display panel 12 from being closed (step S26). As a result, the operation of the close key 20 is ignored until the card type device CRD is extracted by the MPU 11.

  As described above, according to the present embodiment, when the card-type device CRD is inserted in the card slot 17, the maximum closed position (maximum slope angle) of the display panel according to the type of the card-type device CRD. ) To prevent interference between the display panel 12 and the card-type device CRD, so that damage due to interference between the display panel 12 or the card-type device CRD can be prevented. In a range in which interference with the mold device CRD does not occur, it is possible to make the position more highly visible and highly operable.

  In the above description, the case where the control program for controlling the in-vehicle device is stored in advance in the ROM constituting the MPU 11 or the sub MPU 13 has been described. The control program can be recorded in advance, read from these recording media, and installed. It is also possible to provide a communication interface and download the control program via a network such as the Internet or LAN, and install and execute the program. By configuring in this way, it becomes possible to provide a higher function in terms of software or to configure a more reliable vehicle-mounted device.

  Similarly, the card information database can also be configured such that a control program is recorded in advance on recording media such as various magnetic disks, optical discs, and memory cards, and is read and updated from these recording media. It is also possible to provide a communication interface and download and update via a network such as the Internet or a LAN. With this configuration, the card information database can always be kept up-to-date.
