DETAILED DESCRIPTION OF THE INVENTION
Embodiments of a navigation device according to the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram schematically showing a main part of the navigation device according to the embodiment ( 1 ). Here, the same components as those of the navigation apparatus shown in FIG. 6 are denoted by the same reference numerals, and the description thereof is omitted.
[0015]
In the figure, reference numeral 14 denotes image storage means. The image storage means 14 is a driver having a driving characteristic of the driver, in this case a driver having a high traveling frequency in the mountains or a driver having a high traveling frequency along the coast. Characters according to driving characteristics such as being a driver with a high driving frequency on a general road or a driver with a high driving frequency on a highway are stored, for example, in the mountains Driver's driving characteristics and image, such as “Climber-like character” displayed for drivers with high driving frequency, “Surfer-like character” displayed for drivers with high driving frequency along the coast, etc. Are stored and connected to the data processing means 15.
[0016]
Further, the environmental data storage means 16 and the data processing means 15 in which environmental data corresponding to the traveling position of the vehicle, in this case, environmental data such as that the traveling road is in the mountains / coast, are stored.
[0017]
Further, for environmental data (road type data) such as general roads / highways that are often stored in the conventional map data storage means 2, the map data storage means is used without using the environment data storage means 16. 2 can also be used.
[0018]
Be described with reference to the flowchart showing the operation of the data processing unit 15 in FIG. 2 in the next navigation apparatus according to the embodiment (1).
First, driving characteristics based on the driving environment of the driver are obtained from the current position detected by the current position detecting unit 1 and the environmental data stored in the environmental data storage unit 16 (S31).
[0019]
Here, how to obtain the driving characteristics will be described.
1) Current position data detected by the current position detecting means 1 is fetched.
2) The environmental data (whether in the mountains or along the coast, etc.) corresponding to the acquired current position data is acquired from the environmental data storage means 16.
3) By performing the processing of 1) and 2) at any time and integrating them, for example, when traveling time in the mountains accounts for 40% or more of the total traveling time, driving that favors traveling in the mountains If the traveling time along the coast accounts for 40% or more of the total traveling time, the driver prefers traveling along the coast.
[0020]
Next, based on the driving characteristics determined in S31, it is determined whether or not the driver is a driver who likes to travel in the mountains (S32). If it is determined that the driver likes to travel in the mountains, the character corresponding to the driving characteristic, that is, the “mountainer character” is read from the image storage means 14 (S33), and is displayed on the display unit 4 as the vehicle position mark. Control is performed to display the “mountainer character” (S34).
[0021]
On the other hand, if it is determined that the driver does not like traveling in the mountains, it is determined whether or not the driver likes traveling along the coast (S35). If the driver prefers driving along the coast, the character corresponding to the driving characteristic, that is, the “surfer-like character” is read from the image storage means 14 (S 36), and “surfer-like” is displayed on the display unit 4 as the vehicle position mark. Control is performed to display "character" (S37). If it is determined that the driver is not a driver who prefers driving in the mountains or along the coast, that is, if he / she is an average driver, the vehicle position mark (for example, a ▲ mark) as usual is displayed on the display unit 4. (S38).
[0022]
According to the navigation device according to the above embodiment ( 1 ), the current position detected by the current position detecting means 1 and the environmental data stored in the environmental data storage means 16, here in the mountains / in the coast The driving characteristics of the driver can be obtained from the environmental data, and a character corresponding to the driving characteristics can be displayed. For example, if you are a driver with a high frequency of driving in the mountains, you should select “Climber-style character”, and if you are a driver with a high frequency of driving along the coast, select “Surfer-like character”. It can be displayed on the map as a vehicle position mark.
[0023]
The environmental data includes not only the fact that the road is a general road / highway or mountains / along the coast, but also an area where the driver usually travels (a frequently traveled area) as a travel area such as a prefecture. ), For example, when there are many runs in Tokyo, “definite character” is displayed, and when there are many runs in Hokkaido, “Doshinko character” is displayed. You can also.
[0024]
FIG. 3 is a block diagram schematically showing a main part of the navigation device according to the embodiment ( 2 ). Here, the same components as those of the navigation apparatus shown in FIG. 6 are denoted by the same reference numerals, and the description thereof is omitted.
[0025]
In the figure, reference numeral 17 denotes image storage means. The image storage means 17 is a driver's driving characteristics, in this case, a driver having a high driving frequency in Tokyo or a driver having a high driving frequency in Hokkaido. The character according to the driving characteristic obtained based on the traveling area according to the prefecture is stored, for example, “flawless character” displayed for a driver with high driving frequency in Tokyo, Hokkaido, etc. Characters that match the driving characteristics of the driver and the image, such as “Doshinko-like character” displayed for a driver with a high driving frequency, are stored and connected to the data processing means 19.
[0026]
In addition, the environmental data storage means 20 in which the environmental data corresponding to the travel position of the vehicle, here the travel area data for each prefecture such as Tokyo or Hokkaido is stored, and the data processing means 19 are connected. Has been.
[0027]
In addition, since the method for obtaining the driving characteristics of the driver here is the same as the operation of the data processing means 15 in the navigation device according to the embodiment ( 1 ), the description thereof is omitted.
[0028]
The image storage means 18 stores characters corresponding to the area where the driver normally travels (driving characteristics) and the current travel area. For example, a driver with a high travel frequency in Hokkaido can visit Tokyo. A “Midori-san-like character” or the like displayed when going to Tokyo is stored and connected to the data processing means 19.
[0029]
It will be described with reference to operation of the data processing unit 19 in the flowchart shown in FIG. 4 in the next navigation device according to Embodiment (2) of the embodiment.
First, it is determined whether or not the travel area with high travel frequency (the area in which the vehicle travels normally) is a local area such as Hokkaido or Tohoku (S41). If it is determined that the current area is a local area, the current position data is fetched by the current position detecting means 1 (S42), and the current prefecture data is obtained from the fetched current position data and the environmental data stored in the environmental data storage means 20. Is calculated (S43).
[0030]
Next, it is determined whether or not the currently traveling area is Tokyo (S44). If it is determined that the vehicle is currently traveling in Tokyo, the “Midori-san-style character” is read from the image storage means 18 (S45), and the “Midori-san-style character” is displayed on the display unit 4 as the vehicle position mark. (S46).
[0031]
According to the navigation device according to the above embodiment ( 2 ), when the driver is driving the vehicle in an area different from usual, the character corresponding to the situation can be displayed as the vehicle position mark. . For example, when a driver with high driving frequency in the Tohoku region has moved to Tokyo, the “Mitake-style character” can be displayed as the vehicle position mark.
[0032]
FIG. 5 is a block diagram schematically showing a main part of the navigation device according to the embodiment ( 3 ). The navigation device is for region-based image storage means 34 is connected to the data processing means 15 (where the data processing unit 15A is) of the navigation device according to the embodiment (1) shown in FIG.
[0033]
The regional storage means 34 stores characters (such as mountaineer-like characters and surfer-like characters) displayed according to the driving characteristics of the driver, and current position data and environmental data stored by the current position detection means 1. An area-specific character corresponding to the current travel area obtained from the environmental data stored in the means 16 is stored.
[0034]
For example, when a “surfer-like character” is displayed as the vehicle position mark, that is, when a driver who prefers traveling along the coast travels along the coast, In addition, when the “mountainer-like character” is displayed as the vehicle position mark, that is, when a driver who likes to travel in the mountains travels in the mountains, a hail mark or the like is stored.
[0035]
The data processing means 15A does not display the regional character (sea pig mark) when the vehicle travels along the coast when the “mountainer-style character” is displayed as the vehicle position mark. When the “surfer-like character” is displayed as the vehicle position mark, when the vehicle travels along the coast, the sea pig mark is read from the regional image storage means 34 and the map of the display unit 4 Sea pig mark is displayed on the screen.
[0036]
According to the navigation device according to the above embodiment ( 3 ), not only the character corresponding to the driving characteristic of the driver is displayed as the vehicle position mark, but also the driving characteristic and the driving area of the driver, Since characters by region can be displayed, it is possible to realize a navigation device that further suits the driver's preference.
