In addition, an optical sensor may be provided as an ambient brightness detection means, and the ambient brightness is estimated by the control means without using the optical sensor based on sunrise / sunset time data, current position information, etc. It may be. In the above description, the navigation device itself has various map data and route search / guidance programs for guidance processing. However, the navigation device itself obtains data to be distributed through various traffic centers and distribution centers. You may make it guide.

ところで、携帯型ナビゲーション装置の場合、携帯しているユーザが自転車、自動車、電車等どのような移動手段で移動中であるかによりそれに適した案内情報は異なる。例えば、歩いているときや地下鉄に乗車しているときには道路地図は必要なく、一方、バイクや自動車で走行しているときには陸橋や駅の乗り換え案内は必要がない。このような、自転車、自動車、電車等の移動手段の種別（移動種別）の認識は、例えば、現在位置を計測するＧＰＳセンサ２により求めた移動速度、高度、位置情報等、無線通信装置３で受信した交通センタ等から配信される情報や公共交通機関から発せられる電波の受信、操作装置１による手動選択により行うことができる。次に、主としてＧＰＳセンサにより移動種別を推測し、それに相応しい地図情報の表示形態を変化させる例について図２〜図１０により説明する。   By the way, in the case of a portable navigation device, suitable guidance information varies depending on the moving means such as a bicycle, a car, or a train that the user carrying is moving. For example, a road map is not necessary when walking or taking a subway, while there is no need for crossover or station transfer guidance when traveling by motorcycle or car. Such recognition of the type of movement means (movement type) such as a bicycle, a car, or a train is performed by the wireless communication device 3 such as the moving speed, altitude, and position information obtained by the GPS sensor 2 that measures the current position. The information can be received by receiving information distributed from a traffic center or the like, or by receiving radio waves emitted from public transportation, or by manual selection using the operation device 1. Next, an example in which the movement type is estimated mainly by a GPS sensor and the display form of map information suitable for the movement type is changed will be described with reference to FIGS.

図２は徒歩の場合の案内画面の例を示す図である。
ＧＰＳセンサで移動速度を測定し、移動速度が遅い、例えば、時速５ｋｍ以下のような場合は徒歩であると認識して市外地図を表示し、横断歩道や歩道橋、目印としての陸橋等を道路情報として表示する。 FIG. 2 is a diagram showing an example of a guidance screen when walking.
If the moving speed is measured with a GPS sensor and the moving speed is slow, for example, 5 km / h or less, it is recognized as walking and a long distance map is displayed, and a crosswalk, a pedestrian bridge, a crossover as a landmark, etc. Display as information.

図３は自転車の場合の案内画面の例を示す図である。
操作装置による徒歩からの手動切り替えによる認識、或いは移動速度が、例えば、時速１０〜２０ｋｍ程度の場合は自転車であると認識して市外地図を表示し、自転車が通行可能な歩道や、横断歩道、歩道橋、目印としての陸橋等を道路情報として表示する。また、自転車横断帯のない歩道や歩道橋等の自転車を降りる必要のある場所は点滅表示するなど、自転車に乗車したまま走行できる場所と区別できるように表示する。さらに、地図中に上り坂・下り坂等の勾配情報を表示してもよい。この表示により、ユーザは急な坂道を避ける等の行動をとることができる。 FIG. 3 is a diagram showing an example of a guidance screen for a bicycle.
When the operation device recognizes by manual switching from walking or when the moving speed is, for example, about 10-20 km / h, it recognizes that it is a bicycle, displays a city map, and walks and crosswalks where bicycles can pass , Pedestrian bridges, overpasses as landmarks, etc. are displayed as road information. In addition, a place where it is necessary to get off a bicycle such as a sidewalk or a pedestrian bridge without a bicycle crossing zone is displayed in a blinking manner so that it can be distinguished from a place where the user can travel while riding the bicycle. Further, gradient information such as uphill and downhill may be displayed on the map. With this display, the user can take actions such as avoiding a steep slope.

図４は自動車の場合の案内画面の例を示す図である。
ＧＰＳセンサで測定した移動速度が速い、例えば、時速３０〜４０ｋｍ以上の場合は自動車であると認識して道路地図を表示し、渋滞区間などの周辺交通情報や、一方通行等の道路情報を表示する。 FIG. 4 is a diagram showing an example of a guidance screen in the case of an automobile.
When the moving speed measured by the GPS sensor is fast, for example, when the speed is 30 to 40 km / h or more, it is recognized as a car and a road map is displayed, and surrounding traffic information such as a traffic jam section and road information such as one-way traffic are displayed. To do.

図５はバイクの場合の案内画面の例を示す図である。
ＧＰＳセンサで測定した移動速度では自動車との区別はつきにくいので、操作装置による自動車からの手動切り替えでバイクと認識する。自動車の場合と同様の道路地図を表示するが、渋滞などの周辺交通情報にはあまり左右されないのでこれを非表示とし、一方通行等の道路情報を表示する。 FIG. 5 is a diagram showing an example of a guidance screen for a motorcycle.
Since the moving speed measured by the GPS sensor is difficult to distinguish from the automobile, it is recognized as a motorcycle by manual switching from the automobile by the operating device. The same road map as in the case of a car is displayed, but it is not influenced by surrounding traffic information such as traffic jams, so it is not displayed and road information such as one-way traffic is displayed.

図６は電車の場合の案内画面の例を示す図である。
ＧＰＳセンサで測定した移動速度が、例えば、時速８０ｋｍ以上と速く、現在位置（移動位置）が路線とマッチングしている時に電車であると認識して線路周辺の地図を表示する。図示の例では、２画面表示で、一方の画面に線路とその周辺の地図、他方の画面に次駅（ここではＡ駅）周辺の地図を表示している。また、図示は省略するが、乗り継ぎや運行情報などの交通機関情報を表示するようにしてもよい。 FIG. 6 is a diagram showing an example of a guidance screen in the case of a train.
When the moving speed measured by the GPS sensor is as fast as, for example, 80 km / h or more, and the current position (moving position) matches the route, the train is recognized as a train and a map around the track is displayed. In the illustrated example, a two-screen display displays a map of the track and its surroundings on one screen, and a map around the next station (here, A station) on the other screen. Although illustration is omitted, transportation information such as connection and operation information may be displayed.

図７は地下鉄の場合の案内画面の例を示す図である。

When the radio communication device receives radio waves radiated from the subway entrance, or when the GPS sensor response disappears after the subway entrance, it recognizes the subway and displays a ground map around the track. In the example shown in the figure, a two-screen display, a ground map of the track and its surroundings on one screen, a transfer screen from line A to line B on the other screen (transfer from the platform at A1 station to the platform at B1 station on the escalator) Is displayed. Moreover, although illustration is abbreviate | omitted, you may make it display the ground map around a transfer station, or traffic information, such as operation information.

図８はバスの場合の案内画面の例を示す図である。
ＧＰＳセンサで測定した移動速度が速い、例えば、時速３０〜４０ｋｍ以上で、バス停で停車することが検出された場合には、バスであると認識してバス路線を強調表示する。図示の例では、２画面表示で、一方の画面に破線で強調表示したＢ路線から太線で強調表示したＡ路線に乗り継ぐことを示しており、他方の画面にＢ路線のバス停ｂからＡ路線のバス停ａへ移動して乗り継ぐことを示している。また、図示は省略するが、運行情報などの交通機関情報を表示するようにしてもよい。 FIG. 8 is a diagram showing an example of a guidance screen in the case of a bus.
If it is detected that the moving speed measured by the GPS sensor is fast, for example, 30 to 40 km / h or more and the vehicle stops at a bus stop, the bus route is highlighted by recognizing that it is a bus. In the example shown in the figure, it is shown that a transfer is made from the B line highlighted on the broken line on one screen to the A line highlighted on the thick line on one screen, and the A line from the bus stop b on the B line is displayed on the other screen. It shows moving to bus stop a and transferring. Although illustration is omitted, transportation information such as operation information may be displayed.

図９は飛行機の場合の案内画面の例を示す図である。
ＧＰＳセンサで測定した移動速度、高度により飛行機であるに認識し、例えば、地形図を表示する。図示の例では海岸線が表示されている。また、図示は省略するが、乗り継ぎや運行情報などの交通機関情報を表示するようにしてもよい。 FIG. 9 is a diagram showing an example of a guidance screen in the case of an airplane.
Based on the moving speed and altitude measured by the GPS sensor, it is recognized as an airplane and, for example, a topographic map is displayed. In the illustrated example, a coastline is displayed. Although illustration is omitted, transportation information such as connection and operation information may be displayed.

When the position measured by the GPS sensor is at sea, the ship is recognized as a ship, and a conspicuous high-rise building, landform, etc. that can be viewed from the ship are displayed. Although illustration is omitted, transportation information such as connection and operation information may be displayed.

図１１は移動種別に応じて案内画面の表示内容を変える処理フローを示す図である。
現在位置（移動位置）が線路にマッチングしているか否か判断し（ステップＳ１）、移動位置と線路とが一致していれば移動種別は電車と推測する（ステップＳ２）。移動位置が線路とマッチングしていない場合は、地下鉄入口の信号をキャッチした後、ＧＰＳセンサの反応が消失したか否か判断し（ステップＳ３）、地下鉄入口の信号をキャッチした後、ＧＰＳセンサの反応が消失した場合には移動種別は地下鉄と推測する（ステップＳ４）。電車や地下鉄と推測できない場合は、移動スピードが速い、例えば３０〜４０ｋｍ以上かか否か判断し（ステップＳ５）、移動スピードが速い場合にバス停で停車したか否か判断する（ステップＳ６）。バス停で停車する場合はバスと推測し（ステップＳ７）、バス停で停車しない場合は自動車（またはバイク）と推測する（ステップＳ８）。ステップＳ５で移動スピードが速くない場合には、徒歩又は自転車と推測する（ステップＳ９）。こうして、移動手段を推測すると、移動種別に基づいた案内情報を画面に表示する。 FIG. 11 is a diagram showing a processing flow for changing the display content of the guidance screen according to the movement type.
It is determined whether or not the current position (moving position) matches the track (step S1). If the moving position matches the track, the moving type is estimated to be a train (step S2). If the moving position does not match the track, after catching the signal at the subway entrance, it is determined whether the GPS sensor response has disappeared (step S3). After catching the signal at the subway entrance, If the reaction disappears, the movement type is estimated to be subway (step S4). When it cannot be estimated that the train or the subway is used, it is determined whether or not the moving speed is fast, for example, 30 to 40 km or more (step S5). If the moving speed is fast, it is determined whether or not the vehicle is stopped at the bus stop (step S6). When it stops at a bus stop, it is estimated as a bus (step S7), and when it does not stop at a bus stop, it is estimated as a car (or motorcycle) (step S8). If the moving speed is not fast in step S5, it is estimated that the walking or bicycle (step S9). Thus, when the moving means is estimated, guidance information based on the movement type is displayed on the screen.

上記の例においては移動種別に応じて画面に表示する案内情報を変えるようにしたが、移動種別に応じてナビゲーション装置の音声案内における音量を変化させるようにしてもよい。例えば、ユーザが「車→歩行→公共交通機関（電車、地下鉄、バス、飛行機、船舶等）」のように移動手段を変えた場合、ナビゲーション装置の音声案内の音量を、「大→小→ミュート（文字のみ案内）」のように変化させることで、適切な案内を行うことができる。なお、公共交通機関の場合には音量はミュートになるが、ナビゲーション装置にイヤホンが装着可能な場合には、イヤホン装着時にはイヤホンを介して音声案内が聞けるようにする。   In the above example, the guidance information displayed on the screen is changed according to the movement type, but the volume in the voice guidance of the navigation device may be changed according to the movement type. For example, when the user changes the moving means such as “car → walk → public transport (train, subway, bus, airplane, ship, etc.)”, the volume of the voice guidance of the navigation device is changed from “large → small → mute”. It is possible to perform appropriate guidance by changing to “Guided only for characters”. Note that the volume is muted in the case of public transportation, but if earphones can be attached to the navigation device, voice guidance can be heard via the earphones when the earphones are attached.

次に、周囲の明るさを考慮して案内画面の輝度（見やすさ）を変化させるようにした例について処理フローと日の出・日没時刻データを用いて説明する。
図１２は画面を昼画面と夜画面に切り替える処理フローを示す図、図１３は日の出・日没時刻データを説明する図である。
図１２において、ＧＰＳセンサにより現在位置が屋内か否か判断し（ステップＳ１１）、屋内でない場合には移動手段が公共交通機関（電車、地下鉄、バス、飛行機、船舶等）か否か判断する（ステップＳ１２）。公共交通機関か否かは図６〜図１０で説明したような方法で判別する。現在位置が屋内の場合、公共交通機関の場合には、常に昼画面の輝度とする。現在位置が屋内でも公共交通機関でもない場合には、日の出・日没時刻データに基づき昼／夜画面を切り替える。日の出・日没時刻データは、例えば、図１３に示すように、現在位置と月次に応じた日の出・日没時刻に対して、日の出から日没までは昼画面、日没から日の出までは夜画面となるように設定されており、このデータに基づいて昼／夜画面を切り替える。なお、上記の例では現在位置に応じて昼／夜画面を切り替えるようにしたが、携帯型ナビゲーション装置に光センサが備えられている場合には、光センサで検出した周りの明るさに応じて自動的に切り替えるようにしてもよい。 Next, an example in which the brightness (ease of viewing) of the guidance screen is changed in consideration of ambient brightness will be described using a processing flow and sunrise / sunset time data.
FIG. 12 is a diagram showing a processing flow for switching the screen between a day screen and a night screen, and FIG. 13 is a diagram for explaining sunrise / sunset time data.
In FIG. 12, it is determined whether or not the current position is indoor by the GPS sensor (step S11). Step S12). Whether it is public transportation or not is determined by the method described with reference to FIGS. When the current position is indoors, in the case of public transportation, the brightness of the daytime screen is always used. When the current position is neither indoor nor public transportation, the day / night screen is switched based on the sunrise / sunset time data. For example, as shown in FIG. 13, the sunrise / sunset time data is a day screen from sunrise to sunset and a night from sunset to sunrise with respect to the sunrise / sunset time according to the current position and monthly. The screen is set to be a screen, and the day / night screen is switched based on this data. In the above example, the day / night screen is switched according to the current position. However, in the case where the portable navigation device is provided with a light sensor, the screen is switched according to the surrounding brightness detected by the light sensor. You may make it switch automatically.
