Problems solved by technology

[0006] In the above-mentioned navigation device, although the user is guided to the positions that need to be paid attention to when driving, the positions to be guided are only predetermined general dangerous positions such as sharp curves and train crossings.
Therefore, guidance cannot be given to locations that pose a danger in combination with actual driving, such as locations where accidents actually occurred or locations where the driver actually feels dangerous.

[0063]

[0064] figure 1 and figure 2 It is a diagram showing a schematic configuration of the in-vehicle display system 100 of the present embodiment. The in-vehicle display system 100 is mounted on the vehicle 8 and provides various information to a user (typically a driver) in the vehicle compartment, and is configured to include a navigation device 1 and a drive recorder 2 . That is, the navigation device 1 and the drive recorder are mounted on the same vehicle 8 .

[0065] The navigation device 1 has a display, and the screen of the display is installed on a dashboard or the like of the vehicle 8 so that the user can see it. On the other hand, the drive recorder 2 is configured separately from the navigation device 1 and is arranged at an appropriate position in the cabin of the vehicle 8 .

[0066] The navigation device 1 has, as a basic function, a function of displaying a map showing the current position of the vehicle 8 , that is, the vehicle's position, on a di...

no. 2 approach

[0152] Next, a second embodiment will be described. The configuration and operation of the vehicle-mounted display system of the second embodiment are almost the same as those of the first embodiment, so the description will focus on differences from the first embodiment.

[0153]At locations where the vehicle 8 is traveling at a risk, the event sometimes occurs multiple times. Conversely, for a location where a plurality of events occurred, it can be said that it is a location with a high degree of risk that the event may reoccur, and the user needs to drive more cautiously. In the second embodiment, the degree of danger is indicated by displaying signs corresponding to the number of events that have occurred at "event occurrence locations" on the map.

[0154] Figure 15 A diagram showing a state where a warning sign 46 is displayed on the map of the display 13 in the second embodiment. At the "event occurrence location" on the map, a warning mark 46 is displayed as a sig...

Abstract

The invention provides a technology capable of informing the location where an attention is required for driving, adapting to the actual driving. A drive recorder for installation in a vehicle detects occurrence of predetermined events such as an accident, and records an 'event occurrence location' that is a location of the vehicle at the time of the event occurrence. A navigation apparatus obtains the 'event occurrence location' recorded by the drive recorder, and if there is the 'event occurrence location' in the range of a map displayed on a display (13), the navigation apparatus superimposes a warning mark (42) on the event occurrence location. Thereby the location, where the event occurred actually, is indicated on the map. Thus it is possible to inform the location where an attention is required for driving, adapting to the actual driving. As a result, a user can aware of the driving at the location to improve safety.

Description

technical field [0001] The present invention relates to a technique for displaying recorded data recorded by a drive recorder. Background technique [0002] Conventionally, a navigation device mounted on a vehicle called a navigator is known. The navigation device acquires the current position of the vehicle, that is, the position of the own vehicle by using GPS or the like, and displays a map showing the position of the own vehicle on the display. Also, when a destination is set, the navigation device derives a route from the position of the own vehicle to the destination, and guides the user to the route. [0003] In recent navigation devices, various kinds of guidance are provided to users in addition to route guidance. For example, there is known a navigation device that displays a prescribed warning sign at the position on the map when there is a sharp turn or a train crossing in the display area of ​​the map that requires attention during driving, and when the positi...
