Thereby, 1 A of navigation apparatuses perform route guidance by the sound output from the display of the display monitor 14 and the speaker 16 so that it can drive | work along a recommended route with respect to a driver.

  Next, with reference to FIG. 2 and FIG. 3, the break time notification process in the embodiment of the present invention will be described. Here, the break time is a time when it is necessary to take a driving break, and is calculated by adding a predetermined time to the time of departure or the time of the end of the break. For example, when a break must be taken every other hour, the time obtained by adding 1 hour to the departure time is the break time.

  FIG. 2 is a diagram for explaining a display screen of the display monitor 19 displayed when the time comes to a break time. On the display screen, the vehicle position mark 31 is displayed at the current location of the vehicle, overlaid on the map 30 around the vehicle position. When the break time is reached, the speaker 16 outputs a voice 32 instructing the break, “The break time is reached. Please take a break.” Then, after the break time is reached, a place where a break can be taken around the vehicle is searched based on the POI information stored in the map storage device 109. Then, a recommended route to the searched resting place is searched.

  When the recommended route is searched, the searched recommended route 33 is displayed on the display monitor 14 as shown in FIG. Then, the speaker 16 outputs a voice 34 saying “Guide to the resting place. Turn right at the next T-junction.” And route guidance to the resting place is performed.

  Next, the break time notification control process in the first embodiment of the present invention will be described with reference to the flowchart of FIG. The process of FIG. 3 is executed by a program that starts when the ignition switch of the engine is turned on. This program is stored in the memory 102.

  In step S301, a break time is calculated. The break time is calculated by measuring the current time with the clock circuit 111 and adding a predetermined time to the time. As described above, since the process of FIG. 3 is a program that starts when the ignition switch of the engine is turned on, the break time is a time obtained by adding a predetermined time to the departure time or the time when the break is over. In step S302, the clock circuit 111 measures the current time. In step S303, it is determined whether or not the current time has passed the break time. If the current time has passed the break time, an affirmative determination is made in step S303 and the process proceeds to step S307. If the current time has not passed the break time, a negative determination is made in step S303, and the process proceeds to step S304.

  In step S304, based on the signal output from the engine ECU 21, it is determined whether the engine has stopped. In this embodiment, the rest of the driver is detected by detecting the stop of the engine. If the engine has stopped, an affirmative decision is made in step S304 and the process proceeds to step S306. If the engine is not stopped, a negative determination is made in step S304, and the process proceeds to step S305.

  In step S305, it is determined whether or not the sheet position has been changed based on the information on the detection result of the sheet position output from the sheet position detection device 22. In this embodiment, it is detected that the driver has replaced another driver by detecting a change in the seat position. If the driver changes, the driver who has been driving can take a break even if the vehicle is traveling. Therefore, it is not necessary to take a break at the break time calculated in step S301. When the sheet position is changed, an affirmative determination is made in step S305, and the process proceeds to step S306. If the sheet position has not been changed, a negative determination is made in step S305, and the process returns to step S302.

  In step S306, the break time calculated in step S301 is canceled. As a result, even when the current time is the break time calculated in step S301, the sound 32 instructing the break is not output from the speaker 16 or the route guidance to the break place is not performed. The process returns to step S301.

  When returning to step S301, the rest time is calculated again. When the engine is stopped, the break time continues to be canceled, so that a time obtained by adding a predetermined time to the time when the engine operation starts is calculated as the break time. When the driver changes without stopping the engine, a time obtained by adding a predetermined time to the time when the driver changed is calculated as the break time.

  In step S307, a sound instructing a break is output from the speaker 16. In step S308, based on the POI information stored in the map storage device 109, a place where the vehicle can be rested is searched, and a recommended route to the rest place is searched. In step S309, route guidance is performed so that the vehicle can travel according to the recommended route to the searched break place.

The navigation device 1A according to the first embodiment described above has the following operational effects.
(1) Since the engine was stopped, it was determined that the driver took a break and the set break time was canceled. In addition, it is determined that the driver has changed by changing the seat position of the driver seat provided in the vehicle, and the set rest time is canceled. This prevents the set break time from being notified of the break time even though the break has been completed or the driver has changed before the set break time. Can do.

(2) Since the break time set by changing the seat position of the driver seat has been canceled, even if the driver changes without stopping the engine, the break time is set at the set break time. It is possible to prevent notification.

(3) When the set break time is canceled, the next break time can be set based on the canceled time. This is convenient because the driver does not need to reset the rest time after the rest time is canceled.

The navigation device 1A of the first embodiment described above can be modified as follows.
-Other embodiments 1-
Some vehicles can store the driver seat positions of a plurality of drivers (driving position memory). In the case of such a vehicle, when the seat position detected by the seat position detection device 22 becomes a seat position of a different driver, the break time may be canceled. When the driver who is driving adjusts the seat position, it is possible to prevent the driver from being detected as a change of the driver, and the change of the driver can be detected more reliably.

  Next, a break time notification control process in another embodiment 1 of the present invention will be described with reference to the flowchart of FIG. The process of FIG. 4 is executed by a program that starts when the ignition switch of the engine is turned on. This program is stored in the memory 102. In the process of FIG. 4, the same steps as those of the process of FIG. 3 are denoted by the same reference numerals, and differences from the process of FIG.

  If a negative determination is made in step S304, the process proceeds to step S401. In step S401, based on the information on the detection result of the seat position output from the seat position detection device 22, it is determined whether or not the seat position has been changed to a seat position of a different driver. When the seat position is changed to a seat position of a different driver, an affirmative determination is made in step S401 and the process proceeds to step S306. If the seat position has not been changed to the seat position of a different driver, a negative determination is made in step S401 and the process returns to step S302.

When the collation is completed, the intelligent key unit 25 instructs a control circuit (not shown) that controls the door lock / unlock to perform the operation (door lock, unlock, etc.) instructed from the intelligent key 25b. . Moreover, the intelligent key unit 25 outputs the detection result of key ID to the navigation apparatus 1D.

  Next, a break time notification control process according to the fourth embodiment of the present invention will be described with reference to the flowchart of FIG. The process of FIG. 13 is executed by a program that starts when the ignition switch of the engine is turned on. This program is stored in the memory 102. The process of FIG. 13 will be described mainly with respect to differences from the process of FIG.

  If a negative determination is made in step S304, the process proceeds to step S1301. In step S1301, the vehicle speed is detected by the vehicle speed sensor 11c. In step S1302, it is determined whether the vehicle is stopped based on the vehicle speed detected by the vehicle speed sensor 11c. If the vehicle is stopped, affirmative determination is made in step S1302 and the process proceeds to step S1303. If the vehicle is not stopped, a negative determination is made in step S1302, and the process returns to step S302. In step S1303, the intelligent key unit 25 detects the key ID. In step S1304, it is determined whether the key ID has not been detected for a predetermined time or more. If the key ID cannot be detected for a predetermined time or more, an affirmative determination is made in step S1304 and the process proceeds to step S306. If the key ID can be detected, or if the predetermined time has not elapsed since the key ID could not be detected, a negative determination is made in step S1304 and the process returns to step S302.

The navigation device 1D according to the fourth embodiment described above has the following operational effects in addition to the operational effects of the first embodiment.
When the key ID cannot be detected for a predetermined time or more while the vehicle is stopped, there is no driver in the vehicle or around the vehicle for a predetermined time or more. Therefore, since the key ID cannot be detected for a predetermined time or more while the vehicle is stopped, it can be determined that the driver is resting, and the driver's rest can be detected more reliably.

The navigation device 1D of the fourth embodiment described above can be modified as follows.
-Other Embodiments-
If it is ID (driver ID) which can identify a driver, it will not be limited to key ID of intelligent key 25b. This is because if the driver ID cannot be detected for a predetermined time or more, it can be detected that the driver is not in the vehicle for the predetermined time or more.

-Fifth embodiment-
A fifth embodiment of the navigation device according to the present invention will be described with reference to FIGS. In the navigation 1E of the fifth embodiment, when the vehicle height changes while the vehicle is stopped, the break time is reset. FIG. 14 is a diagram showing an overall configuration of a navigation device 1E according to the fifth embodiment of the present invention. Regarding the configuration of the navigation device 1E according to the fifth embodiment of the present invention, the differences from the navigation 1A according to the first embodiment will be mainly described.

  Peripheral circuits of the control device 100 are a memory 102, a parallel I / O 103, an A / D converter 104, a serial I / O 105, a counter 106, a graphic controller 107, an image memory 108, a map storage device 109, an audio output circuit 110, a clock. The circuit 111, interfaces (I / F) 112 and 113, and the like. The I / F 113 is an interface for connecting an auto levelizer control unit (hereinafter, auto levelizer C / U) 26 described later.

  The auto-leveler C / U 26 is a control device that controls the headlamp to an appropriate optical axis height in accordance with a rear vehicle height change in the vehicle. For this reason, vehicle height information is output to the auto levelizer C / U 26 from a vehicle height sensor attached to the suspension arm of the vehicle. The navigation apparatus 1E can acquire information relating to the vehicle height of the vehicle by connecting to the auto levelizer C / U 26.

  Next, a break time notification control process according to the fifth embodiment of the present invention will be described with reference to the flowchart of FIG. The process of FIG. 15 is executed by a program that starts when the ignition switch of the engine is turned on. This program is stored in the memory 102. In the processing of FIG. 15, the same steps as those of FIG. 3 are denoted by the same reference numerals, and different portions from the processing of FIG.

  If a negative determination is made in step S304, the process proceeds to step S1501. In step S1501, the vehicle speed is detected by the vehicle speed sensor 11c. In step S1502, it is determined whether the vehicle is stopped based on the vehicle speed detected by the vehicle speed sensor 11c. If the vehicle is stopped, affirmative determination is made in step S1502 and the process proceeds to step S1503. If the vehicle is not stopped, a negative determination is made in step S1502, and the process returns to step S302. In step S1503, the vehicle height information of the vehicle is acquired from the auto levelizer C / U26. In step S1504, it is determined whether the vehicle height has changed. If the vehicle height has changed, an affirmative decision is made in step S1504 and the process proceeds to step S306. If the vehicle height does not change, a negative determination is made in step S1504, and the process returns to step S302.

The navigation device 1D according to the fifth embodiment described above has the following operational effects in addition to the operational effects of the first embodiment.
When the vehicle height changes while the vehicle is stopped, the driver has got off the vehicle. Therefore, by detecting that the height of the vehicle has changed while the vehicle is stopped, it is possible to determine that the driver is taking a break or that the driver has changed, so that the driver can take a break or change more reliably. Can be detected.

  In the above embodiment, the vehicle speed sensor 11c detects that the vehicle is stopped, but it may be detected from the parking brake or the lever position of the shift lever. In the case of a parking lever, if the parking lever is operating, it is determined that the vehicle is stopped. If the parking lever is not operating, it is determined that the vehicle has not stopped. In the case of the position of the shift lever, when the position of the shift lever is “P” (parking position), it is determined that the vehicle is stopped. When the position of the shift lever is other than “P”, it is determined that the vehicle is not stopped. The stop of the vehicle may be detected based on two or more of the vehicle speed, the operation of the parking brake, and the lever position of the shift lever.

  Although the case where the break time notification device for notifying the break time is mounted on the navigation device has been described, the present invention is also applied to devices mounted on various vehicle-mounted devices other than the navigation device.
