Then, the set destination is released by a destination releasing means 44. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to an improvement in navigation technology.

  In recent years, with the development of electronic technology, the spread of navigation devices for in-vehicle use is remarkable. The navigation device displays the position and direction of the vehicle specified by GPS on the surrounding map, and searches and calculates routes to destinations (also referred to as taxiways and guidance routes) set by facility searches and cursors. Then, along the route, guidance guidance such as a turn direction or a right or left turn at an intersection is performed by a map display or synthetic voice.

  Such a navigation apparatus stores in advance a map data obtained by digitizing roads, place names, buildings, and the like on a map and road data representing a network structure of the road as a database in a storage medium such as a CD-ROM. Then, based on the map data, destination setting is accepted from the user by facility search, map scrolling, etc., and a taxiway to the destination is searched by calculation based on the road data. Then, the guideway obtained by the search and the own vehicle position estimated from the self-contained navigation using the gyroscope and the vehicle speed pulse and the radio navigation using GPS and FM multiplexing are displayed on the screen while performing map matching. The guidance guidance such as the direction of travel is output by voice output or an enlarged view near the intersection.

Conventionally, as shown in FIG. 3, this guidance route presentation and guidance are continued until reaching a point on the road that is the shortest distance from the coordinates of the designated destination, and the mobile phone connected during that time. A device such as controlling the drive mode is also proposed (for example, Patent Document 1).
JP2001-231081

  However, in the conventional technology as described above, depending on the destination, the guidance guidance may not be completed at an appropriate timing, which may be inconvenient. For example, there is a case where guidance to the set position is not necessarily required like a facility having a large number of large parking lots. For example, as shown in FIG. For example, it is a case where the position of the 2nd parking lot in the example of a figure is separated.

  In this case, for the user, for example, although he intends to arrive at the destination when the car is stopped at the second parking lot, since he actually does not travel to the vicinity of the set facility A, on the navigation device side, It cannot be determined that the user has reached the destination. Therefore, if you start running without setting another destination for some reason, such as heading to another parking lot or annex, auto reroute (automatic route recalculation) takes place and unnecessary guidance to facility A continues. There were inconveniences such as annoying.

  This state can be canceled manually, such as by canceling the destination or setting another destination, but it is cumbersome to perform such an operation one by one, and if you forget that operation or If you do not know anything, even if you do not know, guidance to the unnecessary facility A continues in the subsequent run, uncomfortable for the user, it was not a solution.

  The present invention solves the above-described problems of the prior art, and an object of the present invention is to easily end unnecessary route guidance when the vehicle stops near the destination in the navigation technology.

  In order to achieve the above object, according to one aspect of the present invention, in a navigation device that receives a destination setting and guides a route from the departure point to the destination, the vehicle is within a predetermined distance from the destination. Vehicle position determining means for determining whether or not the vehicle is stopped, vehicle stop determining means for determining whether or not the vehicle has stopped when the vehicle position determining means determines that the vehicle is within a predetermined distance from the destination, and the vehicle stop determination And a destination canceling means for canceling the set destination when the means determines that the vehicle has stopped.

  In this way, by determining that the vehicle has stopped within a predetermined range of the destination and canceling the setting of the destination, it is possible to easily eliminate the complexity of unnecessary guidance guidance after arriving substantially at the destination. And it can avoid reliably and can eliminate a user's discomfort and troublesome operation effectively.

  In another aspect of the present invention, the destination canceling means further includes destination cancel selection means for allowing a user to select whether or not to cancel the destination when attempting to cancel the destination.

  In this way, even if you stop near the destination, instead of canceling the destination setting immediately without permission, the facility at the destination Although it has been confirmed, it is possible to make an optimal selection according to the circumstances and circumstances such as driving a little further and seeing the situation and returning with the reroute function.

  In another aspect of the present invention, the vehicle stop determining means further includes a side brake operation determining means for determining whether or not a side brake is applied.

  In this way, the operation state of the side brake, which is often operated when the destination arrives, is used as a criterion for arrival, thereby eliminating simple temporary stops and eliminating the need for complicated equipment and algorithms. This makes it easy to achieve reliable arrival determination.

  In another aspect of the present invention, the vehicle stop determination means further includes gear position determination means for determining whether or not the gear is parked.

  In this way, by using the operation state of the gear, which is often operated to enter the parking when the destination arrives, as a criterion for arrival, it eliminates mere temporary stopping without requiring complicated equipment and algorithms, A simple method makes it easy to achieve reliable arrival determination.

  Note that the method and the program also conform to the above-described embodiments.

  As described above, according to the present invention, in the navigation technology, it is possible to easily end unnecessary route guidance when stopping near the destination, so that the user's discomfort and troublesome operations are also effective. Is resolved.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings. Note that assumptions common to the explanation in the background art and problems are omitted as appropriate.

[1. Constitution〕
The navigation device (hereinafter referred to as “this device”) in the present embodiment receives a destination setting and guides a route from the departure point to the destination. As shown in the configuration diagram of FIG. An absolute position / azimuth detection unit 1 using a gyro, a relative direction detection unit 2 using a gyro, a vehicle speed detection unit 3 for processing vehicle speed pulses obtained from a vehicle, a main CPU for controlling the entire system and its peripheral circuits (“ 4), memory 5-7 for operation, and memory 8 for display.

  The arithmetic control unit 4 is connected via a user interface unit 9 to a display unit 10 for displaying a map or a menu on the screen and an input unit 11 for receiving an operation or information input from a user. Reference numeral 12 denotes a disk control unit such as a CD-ROM for storing and reading various information including map data and road data in the form of a database. Reference numeral 15 denotes a side brake detection unit that detects whether or not the side brake is being pulled by receiving information from the electrical system of the vehicle.

  Moreover, in this apparatus, each means 40-48 shown in FIG. 1 is implement | achieved by controlling the arithmetic control part 4 by computer programs, such as incorporation. Each of these means is a processing means for realizing and executing the following functions and operations.

[2. Action and effect)
The operation procedure of the present embodiment configured as described above is shown in the flowchart of FIG. That is, when there is a route to the destination but the destination has not yet been reached (step S01), the vehicle position determination means 40 determines that the vehicle is within a predetermined distance (R meters) from the destination. For example, it is determined whether or not the radius is within 500 m centering on the destination (step S02, own vehicle position determination processing), and when it is determined that the vehicle is within a predetermined distance (step S02), the vehicle stop determination means 42 It is determined whether or not the vehicle has deviated from the route (step S03) and the vehicle has stopped (step S04, vehicle stop determination process).

  Then, if it is determined that the vehicle has stopped, voice guidance such as “I will arrive near the destination. I will release the destination.” (Step S05), the destination release means 44, Cancel the set destination (destination cancellation processing).

  In this way, by determining that the vehicle has stopped within a predetermined range of the destination and canceling the setting of the destination, it is possible to easily eliminate the complexity of unnecessary guidance guidance after arriving substantially at the destination. And it can avoid reliably and can eliminate a user's discomfort and troublesome operation effectively.

  Here, the condition that the vehicle is traveling on the route is imposed to release the destination (step S03). This is because the side brake may be pulled due to traffic light, traffic jams, etc. When the side brake is pulled when not guiding, it is determined that the vehicle is not guiding, that is, the vehicle has entered the parking lot.

  When making such a determination, it is also desirable to cancel the destination or present it to the user for selection. In this case, when the destination cancellation selection means 46 of the destination cancellation means 44 tries to cancel the destination, the user selects whether to cancel (destination cancellation selection processing). As a specific example, in step S05, a question such as “Arrival near destination. Do you want to cancel the destination?” Is selected and “Destination cancellation” or “Continue guidance” is selected on the screen.

  In this way, even if you stop near the destination, instead of canceling the destination setting immediately without permission, the facility at the destination Although it has been confirmed, it is possible to make an optimal selection according to the circumstances and circumstances such as driving a little further and seeing the situation and returning with the reroute function.

  In the above example, the vehicle stop determination unit 42 uses the side brake detection unit 15 to determine whether the side brake is applied by the side brake operation determination unit 47 (side brake operation determination process). If the brake is applied, it will proceed to release the destination. In this way, the operation state of the side brake, which is often operated when the destination arrives, is used as a criterion for arrival, thereby eliminating simple temporary stops and eliminating the need for complicated equipment and algorithms. This makes it easy to achieve reliable arrival determination.

  However, the release of the destination is not limited to the side brake as described above, and may be performed on the condition that the gear has entered into parking. In this case, the vehicle stop judging means 42 judges whether or not the gear is parked by the gear position judging means 48 (gear position judging processing). It is a waste. In this way, by using the operation state of the gear, which is often operated to enter the parking when the destination arrives, as a criterion for arrival, it eliminates mere temporary stopping without requiring complicated equipment and algorithms, A simple method makes it easy to achieve reliable arrival determination.
