Abstract

Disclosed is a navigation device provided with a radio communication unit, a GPS unit, a positional information acquisition unit, a display unit, and a voice output unit, further provided with a warning operation unit for performing a warning operation, further provided with a recording unit for recording map information, further provided with a warning history generation unit for acquiring point information indicating a point at which the warning operation is detected, and generating warning history information in which the contents of the warning operation and the point information are associated with each other, further provided with a point detection unit for determining, using the positional information acquisition unit and the map information, whether or not the current position is within a predetermined range from an intersection and within a predetermined range from a position indicated by the point information, and further provided with a notification unit for, when the current position is determined to be within the abovementioned ranges, generating information for notification from the warning history information including said point information, and performing output control.

Claims

1. A navigation device including:

a wireless communication portion that performs wireless communication by using an antenna;

a GPS device that performs communication with a GPS (Global Positioning System) satellite;

a position information acquisition portion that acquires position information by using the GPS device;

a display portion or a voice output portion;

a warning operation portion that performs a warning operation by means of the display portion or the voice output portion based on information obtained from between-vehicles communication or between-road-and-vehicle communication by the wireless communication portion; and

a record portion that records map information;

the navigation device comprising;

a warning history generation portion that in a case where the warning operation is performed by the warning operation portion, obtains, from the position information acquisition portion, point information indicating a point where the warning operation is performed, generates warning history information which relates content of the warning operation and the point information to each other, and records the warning history information into the record portion;

a point detection portion that determines whether or not a position indicated by the position information obtained from the position information acquisition portion is in a predetermined area from an intersection indicated by the map information, and determines whether or not the position indicated by the position information is in a predetermined area from a position indicated by the point information which is included in the warning history information; and

a notification portion that in a case where it is determined by the point detection portion that the position indicated by the position information is in the predetermined area, generates notification information that indicates content of the warning history information which includes the point information, and based on the notification information, controls the display portion or the voice output portion to perform a notification operation.

2. The navigation device according to claim 1, wherein

in a case where the warning operation is performed by the warning operation portion, the warning history generation portion includes situation information, which indicates a traveling situation of a vehicle on which the navigation device is mounted, into the warning history information and records the situation information into the record portion;

the point detection portion determines whether or not the position indicated by the position information acquired by the position information acquisition portion is in a predetermined area from the intersection indicated by the map information and from the position indicated by the point information which is included in the warning history information, and determines whether or not the traveling situation of the vehicle agrees with the traveling situation indicated by the situation information; and

in a case where it is determined by the point detection portion that the position indicated by the position information acquired by the position information acquisition portion is in the predetermined area and the traveling situations agree with each other, the notification portion generates the notification information which indicates the content of the warning history information which includes the situation information, and based on the notification information, controls the display portion or the voice output portion to perform the notification operation.

3. The navigation device according to claim 2, further comprising a speed detection portion or an angle detection portion, wherein

in the case where the warning operation is performed by the warning operation portion, the warning history generation portion detects, from the speed detection portion, a traveling speed of the vehicle on which the navigation device is mounted, or detects, from the angle detection portion, a traveling direction of the vehicle, and generates the situation information based on the detected traveling speed or the detected traveling direction;

the point detection portion uses the speed detection portion or the angle detection portion to compare the raveling speed or the traveling direction of the vehicle with the traveling speed or the traveling direction indicated by the situation information, and determines whether or not a comparison result meets a predetermined condition; and

in a case where it is determined by the point detection portion that the position indicated by the position information acquired by the position information acquisition portion is in the predetermined area and the comparison result meets the predetermined condition, the notification portion generates the notification information which indicates the content of the warning history information which includes the situation information, and based on the notification information, controls the display portion or the voice output portion to perform the notification operation.

4. The navigation device according to claim 2, wherein

in the case where the warning operation is performed by the warning operation portion, the warning history generation portion uses an ITS (Intelligent Transportation System) to detect the number or types of vehicles around the vehicle on which the navigation device is mounted, and based on the detected number or types, generates the situation information;

the point detection portion uses the ITS to compare the number or types of peripheral vehicles of the vehicle with the number or types of vehicles around indicated by the situation information, and determines whether or not a comparison result meets a predetermined condition;

in a case where it is determined by the point detection portion that the position indicated by the position information obtained from the position information acquisition portion is in the predetermined area and the comparison result meets the predetermined condition, the notification portion generates the notification information which indicates the content of the warning history information which includes the situation information, and based on the notification information, controls the display portion or the voice output portion to perform the notification operation.

5. The navigation device according to claim 1, wherein

the warning operation portion uses an ITS to perform the between-vehicles communication or the between-road-and-vehicle communication, thereby performing the warning operation;

and

the warning history generation portion generates the warning history information by relating the point information acquired by the position information acquisition portion to information which indicates the content of the warning operation that is performed by using the ITS.
