That is, the control / notification determination unit 26 extracts display data that prompts the load not to be applied to the opening / closing member 12 such as “please press the open / close switch without applying a load” from the ROM 27, and the display output circuit 22. To be output to the display unit 16. Alternatively, audio data that prompts the load not to be applied to the similar opening / closing member 12 is extracted from the ROM 27 and output to the speaker 19 via the audio output circuit 23.
Thereafter, the sequence returns to step ST302, and the above-described processing is repeated.

  On the other hand, if the control / notification determination unit 26 determines in step ST305 that the open / close switch has not been pressed (“NO” in step ST305), the process in step ST306 is skipped, and the sequence returns to step ST302. Repeat the process.

  On the other hand, when the load determination unit 25 determines in step ST302 that the load of the opening / closing member 12 is not equal to or greater than the threshold ("NO" in step ST302), the control / notification determination unit 26 then closes the opening / closing member 12. Is permitted (step ST307). That is, the control / notification determination unit 26 enables the opening / closing member 12 to be closed by enabling the function of the opening / closing switch of the operation unit 18, and when the opening / closing switch is pressed, the motor drive By driving the motor 14 via the circuit 21, the opening / closing member 12 is shifted to the closed state.

  As described above, according to the first embodiment of the present invention, when the opening / closing member 12 is in the open state, a beverage or the like is placed on the opening / closing member 12 or the weight is applied, whereby a load greater than a predetermined threshold is applied. When added, a notification indicating that a load is not applied to the opening / closing member 12 is given by display or sound, and the opening / closing member 12 is prohibited from shifting to the closed state. In the placed state, the closing operation is not performed, the beverage is not tilted and liquid or the like is not spilled on the opening / closing member 12, and the opening / closing member 12 is not operated in a state where a load is applied. Further, breakage of the opening / closing mechanism 13 can be prevented.

  In step ST401, when the opening / closing determination unit 24 determines that the opening / closing member 12 is not closed (step ST401 “NO”), the sequence ends. On the other hand, in step ST401, when the open / close determining unit 24 determines that the open / close member 12 is closed (step ST401 “YES”), the load determining unit 25 then determines whether the load of the open / close member 12 is equal to or greater than the threshold value. Is determined (step ST402). In step ST402, when the load determination unit 25 determines that the load of the opening / closing member 12 is equal to or greater than the threshold value, the control / notification determination unit 26 then outputs an output indicating that no load is applied to the opening / closing member 12 ( Step ST403). Next, the control / notification determination unit 26 prohibits the opening operation of the opening / closing member 12 (step ST404). In other words, the control / notification determination unit 26 prohibits the opening / closing member 12 from shifting to the open state by disabling the function of the opening / closing switch for opening / closing the opening / closing member 12 that is normally operable by the operation unit 18. .

  Next, the control / notification determination unit 26 determines whether the open / close switch is pressed (step ST405). In step ST405, when the control / notification determination unit 26 determines that the open / close switch has been pressed (step ST405 “YES”), the control / notification determination unit 26 then outputs an output indicating that no load is applied to the open / close member 12 (step ST406). ). Thereafter, the sequence returns to step ST402, and the above-described processing is repeated. On the other hand, when the control / notification determination unit 26 determines in step ST405 that the open / close switch has not been pressed (“NO” in step ST405), the process in step ST406 is skipped, and the sequence returns to step ST402. Repeat the process. On the other hand, when the load determination unit 25 determines in step ST402 that the load of the opening / closing member 12 is not equal to or greater than the threshold value (step ST402 “NO”), the control / notification determination unit 26 then opens the opening / closing member 12. Is permitted (step ST407). That is, the control / notification determination unit 26 enables the switching of the opening / closing member 12 by enabling the function of the opening / closing switch of the operation unit 18, and when the opening / closing switch is pressed, the motor drive By driving the motor 14 via the circuit 21, the open / close member 12 is shifted to the open state.

  As described above, according to the second embodiment of the present invention, when the opening / closing member 12 is in the closed state, for example, when a long object such as a bag is loaded on the vehicle, the load exceeding the predetermined threshold is placed on the opening / closing member 12. When added, a notification indicating that a load is not applied to the opening / closing member 12 is given by display or sound, and the switching of the opening / closing member 12 to the open state is prohibited, so that the opening / closing member 12 is in the closed state. However, the opening / closing member 12 and the opening / closing mechanism 13 can be prevented from being damaged by not operating the opening / closing member 12 in a state where a load is applied.

Embodiment 3 FIG.

The in-vehicle navigation device 10 according to Embodiment 3 of the present invention includes an opening / closing member. The vehicle navigation device 10 according to the third embodiment of the present invention is configured to perform notification indicating that no load is applied by display or sound. Based on the load applied to the opening and closing member 12 and the size of the object placed on the opening and closing member 12, the switching of the opening and closing member 12 to the closed state (open state) is controlled and displayed or notified by voice. Yes, the in-vehicle navigation device 10 according to Embodiment 1 of the present invention shown in FIG. 1 determines whether the object sensor 29 for detecting the presence or absence of an object and the size of the object are equal to or larger than a threshold value. It is obtained by adding the object determination unit 30.
In the following, the same or similar configuration as the invention according to the first embodiment of the present invention shown in FIG.

  The object sensor 29 detects the presence or absence of an object placed on the opening / closing member 12, and detects the size of the object when the object is present. For example, the object sensor 29 is a touch panel, an infrared sensor, a camera, or a light. Consists of sensors and the like. The size of the object detected by the object sensor 29 is transmitted to the object determination unit 30 of the electronic control unit 20.

  The object determination unit 30 detects the object by comparing the size of the object placed on the opening / closing member 12 detected by the object sensor 29 with a preset threshold (for example, a size equivalent to a paper cup). It is determined whether the size of the selected object is equal to or greater than a threshold value. The determination result of whether or not the size of the object placed on the opening / closing member 12 determined by the object determination unit 30 is equal to or larger than the threshold value is transmitted to the control / notification determination unit 26.

  When the opening / closing determination unit 24 determines that the opening / closing member 12 is in the open state (closed state), the control / notification determination unit 26 sets a load applied to the opening / closing member 12 in advance by the load determination unit 25. When it is determined that it is greater than or equal to the threshold value, or when it is determined by the object determination unit 30 that the size of the object placed on the opening / closing member 12 is greater than or equal to the threshold value set in advance, the opening / closing member 12 is prohibited from shifting to the closed state (open state), and notification data (display data or voice data) indicating that no load is applied to the opening / closing member 12 or notification data (display data or voice) indicating that no object is placed. Data).

Next, operation | movement of the electronic control part 20 of the vehicle-mounted navigation apparatus 10 comprised as mentioned above is demonstrated.

FIG. 6B shows an opening / closing control process when the opening / closing member 12 is closed.
Hereinafter, the same or similar configuration as the operation of the electronic control unit 20 of the in-vehicle navigation device 10 according to the first and second embodiments of the present invention shown in FIGS. Simplify the description.

  First, in the opening / closing control process for the case where the opening / closing member 12 is in the open state shown in FIG. 6A, the opening / closing determination unit 24 determines whether the opening / closing member 12 is open (step ST301). In step ST301, when the open / close determining unit 24 determines that the open / close member 12 is not open (step ST301 “NO”), the sequence ends. On the other hand, when the opening / closing determination unit 24 determines that the opening / closing member 12 is open in step ST301 (step ST301 “YES”), the load determination unit 25 then determines whether the load of the opening / closing member 12 is equal to or greater than the threshold value. Is determined (step ST302). If the load determination unit 25 determines in step ST302 that the load of the opening / closing member 12 is not equal to or greater than the threshold value, then the object determination unit 30 determines whether there is an object on the opening / closing member 12 (step ST601). . That is, the object determination unit 30 compares the size of the object placed on the opening / closing member 12 detected by the object sensor 29 with a threshold value set in advance (for example, a size corresponding to a paper cup). Thus, it is determined whether or not the size of the object placed on the opening / closing member 12 is equal to or greater than a threshold value.

  In this step ST601, when the object determining unit 30 determines that the size of the object is greater than or equal to the threshold (step ST601 “YES”), or in step ST302, the load determining unit 25 determines that the load is greater than or equal to the threshold. If so (step ST302 “YES”), the control / notification determination unit 26 then outputs an output indicating that no object is placed / load is not placed on the opening / closing member 12 (step ST602). In other words, the control / notification determination unit 26 adds display data from the ROM 27 such as “Do not place an object on the opening / closing member” or a load such as “Do not apply a load”. The display data that prompts the user to cease is extracted and output to the display unit 16 via the display output circuit 22. Alternatively, audio data having the same content is extracted from the ROM 27 and output to the speaker 19 via the audio output circuit 23.

Next, the control / notification determination unit 26 prohibits the closing operation of the opening / closing member 12 (step ST304). Next, the control / notification determination unit 26 determines whether the open / close switch has been pressed (step ST305). In step ST305, when the control / notification determination unit 26 determines that the open / close switch has been pressed ("YES" in step ST305), the object is not placed on the open / close member 12 / no load is applied. Output is performed (step ST603). That is, the control / notification determination unit 26 displays the display data prompting not to place an object such as “Please remove the object on the opening / closing member and then press the opening / closing switch” from the ROM 27 or “Open / close switch without applying a load”. The display data for urging not to apply a load such as “Please press” is extracted and output to the display unit 16 via the display output circuit 22. Alternatively, audio data having the same content is extracted from the ROM 27 and output to the speaker 19 via the audio output circuit 23.
Thereafter, the sequence returns to step ST302, and the above-described processing is repeated.

  On the other hand, if the control / notification determination unit 26 determines in step ST305 that the open / close switch has not been pressed (“NO” in step ST305), the process in step ST603 is skipped, and the sequence returns to step ST302. Repeat the process. On the other hand, when the object determination unit 30 determines in step ST601 that the size of the object is not equal to or greater than the threshold (step ST601 “NO”), the control / notification determination unit 26 then closes the opening / closing member 12. Allow (step ST307).

  In addition, the opening / closing control process for the case where the opening / closing member 12 in FIG. 6B is in the closed state includes steps ST301, ST302, ST304, ST305, ST307 in FIG. 6A and steps ST401, ST402, ST404 shown in FIG. , ST405, and ST407, and the description thereof is omitted.

  As described above, according to the third embodiment of the present invention, when the opening / closing member 12 is in the open state (closed state), a load of a predetermined threshold value or more is applied to the opening / closing member 12 or the opening / closing member 12 has a predetermined threshold value or more. When an object of a size is placed, a notification indicating that a load is not applied or a notification indicating that no object is placed is performed on the opening / closing member 12 by display or sound, and the opening / closing member 12 is closed (opened state). ), The load is not more than the threshold value, for example, when a paper cup containing a small amount of liquid is placed on the opening / closing member 12, but the opening / closing member 12 is opened / closed. Even when the operation causes the paper cup to fall down and the liquid in the spilling out causes damage to the display unit 16 or the like of the opening / closing member 12, the movement of the opening / closing member 12 can be controlled. 12 breakage It is possible to prevent exactly.

  In addition, in the in-vehicle navigation device 10 according to Embodiment 1-3 of the present invention, display when detecting a load or object that is equal to or greater than a predetermined threshold, audio output processing, and load or object that is equal to or greater than the predetermined threshold are detected. Closed operation (opening operation) prohibition process, display when the open / close switch is pressed while closing operation (opening operation) is prohibited, and audio output processing are configured, but all these processes are not performed Alternatively, only a part may be implemented.

  Moreover, in the vehicle-mounted navigation apparatus 10 according to Embodiment 1-3 of the present invention, the display unit 16 is configured to output display data extracted from the ROM 27, but the output by the display unit 16 has a notification function. For example, the display unit 16 may be configured to simply output blinking of light or the like.

  Further, in the in-vehicle navigation device 10 according to Embodiment 1-3 of the present invention, it has been described that the in-vehicle navigation device 10 operates in the ON state (ACC power source is ON), but the battery power source is used. By adopting such a configuration, the same operation may be performed even when the ACC power source is in the OFF state.

  Further, in the in-vehicle navigation device 10 according to Embodiment 1-3 of the present invention, when detecting a load or an object having a predetermined threshold value or more, a notification unit that notifies the outside is built in the in-vehicle navigation device 10. Although it comprised by the display part 16 and the speaker 19, it is not restricted to this, You may comprise an alerting | reporting part by what is connected to the vehicle-mounted navigation apparatus 10 externally.
