FIG. 4 is a flowchart of an example of the information notification process of the navigation device according to the first embodiment. In the flowchart of FIG. 4, the navigation device 300 first waits until the vehicle stops and the engine stops (step S401: No loop). When the engine stops (step S401: Yes), The engine is stopped and the measurement of force time (stop time T) is started (step S402). Even if the engine is stopped, the navigation device 300 is still on. Specifically, for example, the ignition key is in the “ACC” state, and the navigation device 300 is not turned off.

[0051] Then, it is determined whether or not the current location of the vehicle is a predetermined location (step S403). The place A certain place is a place where there is a possibility of stopping for a certain period of time. Specifically, for example, there are a vicinity of a railroad crossing or a signal, a rotary of a station, and the like. In addition, it may be possible to include factors such as time zones. Specifically, it may be determined whether or not it is a commuting time zone with a heavy traffic volume.

 [0052] If it is determined in step S403 that the current location of the vehicle is a predetermined location (step S403: Yes), it is determined whether or not the stop time is equal to or greater than a threshold (step S404). Here, the threshold value of the stop time is set to, for example, 20 seconds, which may be set to the idling continuation time for consuming the same fuel as that required for each engine start.

 If it is determined in step S404 that the stop time is greater than or equal to the threshold (step S404: 丫 63), a fuel saving amount 0 is calculated (step 3405). Specifically, the fuel consumption A per unit time during idling and the fuel consumption B consumed each time the engine is started are obtained, and the fuel consumption A per unit time and idling are stopped. Then, by multiplying the powerful stop time T, the fuel consumption C is calculated when it is assumed that the engine is idling.

Thereafter, it is determined whether or not the engine has been started (step S409). If it is determined in step S409 that the engine has started (step S409: Yes), the series of processing ends. In step S409, the calculated information may be stored after determining that the engine has started.

 [0057] On the other hand, if it is determined in step S409 that the engine has started! /! (Step S409: No), the processing from step S404 is performed again. If it is determined in step S404 that the stop time is not greater than or equal to the threshold value (step S404: No), the processing after step S409 is performed.

 [0058] If it is determined in step S403 that the current location is not a predetermined place (step S403: No), it is determined whether a hazard has been issued (step S410). If it is determined in step S410 that a hazard has been issued (step S410: Yes), the processing after step S404 is performed.

 [0059] If it is determined in step S410 that a hazard has been issued (step S410: No), it is determined whether the current location is a recommended idling stop location (step S411). Here, the recommended idling stop location is a point where idling stop is desired, and specific examples include places with very high traffic volume, near schools and hospitals. If it is determined in step S411 that the recommended idling stop location is given (step S411: Yes), the processing after step S404 is performed. If it is determined in step S411 that the recommended idling stop location is not! / (Step S411: No), the series of processing ends.

Specific examples include the vicinity of a railroad crossing, the vicinity of a signal, and a rotary of a station. If it is determined in step S803 that the current location of the vehicle is a predetermined location (step S803: Yes), it is determined whether the idling time is greater than or equal to a threshold value (step S804). Here, the idling time threshold is set to, for example, 20 seconds, which may be set to the duration of idling that consumes fuel equivalent to that consumed each time the engine is started.

 In step S804, when it is determined that the idling time is equal to or greater than the threshold (step S804: Yes), the idling stop is notified (step S805). The notification may be displayed on the display 313 or by voice notification using the speaker 310.

[0094] Then, a fuel waste amount d is calculated (step S806). Specifically, the fuel consumption a per unit time during idling and the fuel consumption b consumed every time the engine is started are obtained, and the fuel consumption a per unit time a and the idling time t are obtained. And squared To calculate the fuel consumption c when consumed by idling. Then, by subtracting the obtained fuel consumption b every time the engine is started from the fuel consumption consumed by idling, the waste fuel consumption d is calculated.

To S811). The number of hazards set to four or more is set based on the possibility of stopping for a certain period of time, and the number of hazards is not limited to this. Also, in addition to determining whether or not a hazard is being applied, it may be determined whether or not the gear has been put into a-neutral position or parking position.

 [0100] If it is determined in step S811 that the hazard has been issued four times or more (step S811: Yes), the processing after step S804 is performed. On the other hand, if it is determined that the hazard has not been issued four or more times (step S811: No), it is determined whether or not the current location is a recommended idling stop location (step S812). Here, the idling stop recommended place is, for example, a point where idling stop is desired, such as a place with very high traffic volume, near a school or a hospital. If it is determined in step S812 that the recommended idling stop location is set (step S812: Yes), the processing after step S804 is performed. Further, if it is determined in step S812 that it is not a recommended idling stop place (step S812: No), the idling is not required to stop, and thus a series of processing is ended.
