2. Description of the Related Art Conventionally, there is known a navigation device that can specify a point to be registered while the vehicle is running, write it in a memory, and edit the designated registered point after stopping. In this navigation device, it is possible to edit the name of the point read from the memory after stopping, etc. over time.
JP-A-8-327373 (page 3-4, FIGS. 1-4)

  By the way, in the navigation device disclosed in Patent Document 1, it is possible to specify a point that is intriguing while the vehicle is running with a simple operation. However, if the number of unedited points increases, the number of points to be edited that are displayed during editing increases, and the operability deteriorates. In order to avoid this, it is necessary to read unnecessary points from the memory and delete them each time when the vehicle stops after specifying the points, and the operation becomes complicated. In addition, generally, there are few users who delete points of interest every time, and as a result, the number of unedited points increases.

  The present invention was created in view of the above points, and an object of the present invention is to provide a navigation device that can prevent deterioration in operability due to an increase in unedited registration points.

  In order to solve the above-described problems, a navigation device according to the present invention includes a map display unit that displays a map image in a predetermined range while the vehicle is traveling, and a point designation that specifies a point on the map image displayed by the map display unit. Temporary registration means for temporarily registering the point designated by the point designation means, and temporary registration cancellation for canceling the temporary registration at this point when the point temporarily registered by the temporary registration means passes without stopping after that. Means. As a result, the temporary registration at this point is canceled when passing without stopping after the point designated at the time of passing and temporarily registered, avoiding an increase in the number of points left unattended after designation And deterioration of operability can be prevented.

  In addition, it is desirable to further include a main registration unit that performs main registration corresponding to the point when the vehicle is subsequently stopped at the point temporarily registered by the temporary registration unit. As a result, it becomes possible to perform the main registration for the points where the interest has been maintained and stopped again among the points designated at the time of passing and temporarily registered, and the operation by reducing the number of target points for the main registration It becomes possible to improve the performance.

  Further, it is preferable that the main registration means described above includes a display process of an edit screen relating to a point that is a target of the main registration, and a process of accepting a user input to the edit screen. As a result, when the user is interested and goes to that point again and stops, editing related to that point can be performed.

  A route search means for searching for an optimum travel route by performing route search processing using the temporarily registered point as a transit or destination when the vehicle stops after temporary registration is performed by the temporary registration means described above; It is desirable to further include route guidance means for guiding the vehicle traveling along the travel route obtained by the search by the route search means. As a result, it is possible to reconfirm the existence of a point that has been designated and temporarily registered at the time of vehicle travel and to guide the travel to that point.

  Further, it is desirable that the temporary registration canceling unit described above cancels the temporary registration at the point where the temporary registration by the temporary registration unit is not performed by the main registration unit within a predetermined period. Thereby, it is possible to cancel the temporary registration for the point designated at the time of passing and for which the temporary registration has been performed, and the point left after that, and it is possible to reduce the trouble of canceling the temporary registration for the point that has lost interest.

  Hereinafter, an in-vehicle navigation device according to an embodiment to which the present invention is applied will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration of a navigation device according to an embodiment. The navigation device shown in FIG. 1 includes a navigation controller 1, a DVD 2, a disk reading device 3, a remote control (remote control) unit 4, a vehicle position detection unit 5, a display device 6, and an audio unit 7.

  The navigation controller 1 controls the overall operation of the navigation device. The navigation controller 1 realizes its function by executing a predetermined operation program using a CPU, ROM, RAM, or the like. The detailed configuration of the navigation controller 1 will be described later.

  The DVD 2 is an information recording medium that stores map data necessary for map display, facility search, route search, and the like. This DVD 2 stores map data in units of rectangular figure leaves divided into appropriate sizes by longitude and latitude. The map data of each leaf can be specified and read by designating the leaf number.

  The disc reader 3 can be loaded with one or more DVDs 2 and reads map data from any of the DVDs 2 under the control of the navigation controller 1. The loaded disc is not necessarily a DVD but may be a CD. Further, both DVD and CD may be selectively loaded. Alternatively, a hard disk device may be used instead of the DVD 2 and the disk reader 3.

  The remote control unit 4 includes a joystick for designating directions such as up, down, left, and right, and various operation keys such as a numeric keypad for inputting numbers and a “decision key” for confirming various settings. A signal is output to the navigation controller 1. The vehicle position detection unit 5 includes, for example, a GPS receiver, an orientation sensor, a distance sensor, and the like, detects the vehicle position (longitude, latitude) at a predetermined timing, and outputs a detection result.

  Based on the drawing data output from the navigation controller 1, the display device 6 displays various images such as a map image around the vehicle position and a menu screen image necessary for the main registration process at the designated location. The audio unit 7 outputs a guidance voice or the like generated based on the voice signal input from the navigation controller 1 into the vehicle interior.

  Next, a detailed configuration of the navigation controller 1 will be described. A navigation controller 1 shown in FIG. 1 includes a map buffer 10, a map read control unit 12, a map drawing unit 14, a vehicle position calculation unit 20, a route search processing unit 22, a guidance route drawing unit 24, a voice guidance unit 26, and a destination setting. Unit 30, provisional registration processing unit 40, passage determination unit 42, cancellation processing unit 44, stop determination unit 46, main registration processing unit 48, input processing unit 50, and display processing unit 60.

  The map buffer 10 temporarily stores map data read from the DVD 2 by the disk reader 3. The map reading control unit 12 outputs a request for reading a predetermined range of map data to the disk reading device 3 in accordance with the vehicle position calculated by the vehicle position calculating unit 20 and an instruction from the input processing unit 50. Based on the map data stored in the map buffer 10, the map drawing unit 14 performs drawing processing necessary to display a map image and creates map image drawing data.

  The vehicle position calculation unit 20 calculates the vehicle position based on the detection data output from the vehicle position detection unit 5, and if the calculated vehicle position is not on the road of the map data, the vehicle position is calculated. Perform map matching processing to correct.

  The route search processing unit 22 performs route search processing for a travel route (guidance route) that connects a departure point and a destination (or a waypoint) according to a predetermined search condition. The guide route drawing unit 24 generates guide route drawing data for displaying the guide route obtained by the route search processing by the route search processing unit 22 so as to overlap the map. The voice guidance unit 26 generates a voice signal such as intersection guidance necessary for guiding the vehicle along the guidance route obtained by the search process by the route search processing unit 22. The destination setting unit 30 sets a destination or waypoint for the route search process. For example, the destination setting unit 30 searches for a facility that satisfies a search condition specified by the user and sets it as a destination.

  The temporary registration processing unit 40 temporarily registers the designated point when an arbitrary position on the map image displayed while the vehicle is traveling (this temporary registration is referred to as “temporary registration”). Process). The passage determination unit 42 determines whether or not the vehicle has passed the temporarily registered point. The cancellation processing unit 44 performs processing for canceling temporary registration of points that satisfy a predetermined condition. For example, the provisional registration is canceled for the provisional registration point where the passage determination unit 42 has made a passage determination or the provisional registration point for which a predetermined period has elapsed after provisional registration. The stop determination unit 46 determines whether or not the vehicle has stopped at the temporarily registered point. The main registration processing unit 48 performs processing for registering a point having a predetermined condition from the temporarily registered points (this registration is referred to as “main registration”). For example, the main registration process is performed for a point where the stop determination unit 46 determines that the vehicle has stopped after the temporarily registered points. In the main registration process, a main registration menu image that also serves as an editing screen is generated by the main registration processing unit 48, and the user operates the remote control unit 4 to input predetermined editing items while viewing the main registration menu image. Is done.

  The input processing unit 50 outputs commands for performing operations corresponding to various operation instructions input from the remote control unit 4 to each unit in the navigation controller 1. The display processing unit 60 receives the map image drawing data generated by the map drawing unit 14 and displays a predetermined range of map images on the screen of the display device 6 based on the drawing data. When the main registration menu image data generated by the main registration processing unit 48 and the guidance route drawing data generated by the guidance route drawing unit 24 are input, the display processing unit 60 converts the drawing data into a map image. The images are displayed on the screen of the display device 6 again.

  The disk reading device 3, the vehicle position detection unit 5, the map buffer 10, the map reading control unit 12, the map drawing unit 14, the vehicle position calculation unit 20, and the display processing unit 60 described above are used as the map display means, the remote control unit 4 and the input processing. The unit 50 is a point designation unit, the temporary registration processing unit 40, the passage determination unit 42 is a temporary registration unit, the cancellation processing unit 44 is a temporary registration cancellation unit, the stop determination unit 46, and the main registration processing unit 48 are main registration units. Further, the route search processing unit 22 corresponds to the route search means, and the guidance route drawing unit 24, the voice guidance unit 26, and the display processing unit 60 correspond to the route guidance means.

  The navigation device of the present embodiment has such a configuration, and next, an operation in the case where registration is performed by designating an arbitrary point included in the map image displayed while the vehicle is traveling will be described. FIG. 2 is a flowchart showing an operation procedure of provisional registration performed while the vehicle is traveling. The temporary registration processing unit 40 determines whether or not temporary registration is instructed by designating an arbitrary position in the map image displayed while the vehicle is traveling (step 100). For example, by operating the remote control unit 4, designation of an arbitrary position in the map image and an instruction for temporarily registering the designated arbitrary position are performed. If no provisional registration instruction is given, a negative determination is made and the determination in step 100 is repeated. If a temporary registration instruction is given, an affirmative determination is made in step 100, and the temporary registration processing unit 40 temporarily registers a point corresponding to the designated arbitrary position (step 101). In this temporary registration process, at least the address of the target point and the temporary registration date and time are stored in a built-in memory or the like.

  FIG. 3 is a flowchart showing an operation procedure for performing the main registration or the temporary registration cancellation with respect to the temporarily registered point. For example, it is assumed that the operation shown in FIG. 3 is started when the running vehicle stops and the key switch is turned off, and then the engine key is turned again and the accessory switch is turned on.

First, the temporary registration processing unit 40 determines whether there is temporary registration information (step 200). An affirmative determination is made when there is one or more temporarily registered points. Next, the cancellation processing unit 44 determines whether or not there is provisional registration information that has passed for a certain period of time, that is, whether or not there is a point that has passed for a certain period of time since provisional registration (step 201). If there is provisional registration information after a certain period of time, an affirmative determination is made, and the cancellation processing unit 44 performs a process of canceling provisional registration at a point after the certain period has elapsed (step 202). Thereafter, the temporary registration processing unit 40 determines whether there is temporary registration information that has not been canceled (step 203). If there is provisional registration information that has not been canceled, an affirmative determination is made. After that, or when there is no provisional registration information after a certain period of time and a negative determination is made in the determination of step 201, the contents of the provisional registration information (address and provisional registration date and time) are displayed in a list format ( Step 204)
Next, the route search processing unit 22 determines whether or not a route search is instructed by setting a destination or a waypoint (step 205). If there is no temporary registration information and a negative determination is made in step 200, or if all the temporary registration information is canceled and a negative determination is made in step 203, this step is performed. The process proceeds to the determination operation 205.

  For example, the destination setting unit 30 performs a process of setting a route search destination or waypoint according to the user's operation. The user selects the temporary registration point displayed in the list format in step 204. It can be specified as a destination or waypoint for route search. In addition, when the temporarily registered point displayed in the list format is not designated as the destination or waypoint, the destination setting unit 30 temporarily registers the travel route to the destination set separately from these points. Process to include the point as a transit point. However, temporary registration points that deviate significantly from the route toward the destination due to the positional relationship between the vehicle position and the destination are excluded from the intermediate points. Whether or not it deviates significantly may be judged based on the distance from the line connecting the vehicle position and the destination to each point of temporary registration, or when the point of temporary registration is included in the transit point Judgment may be made based on the difference in travel time when not included. After the destination and waypoint are set in this way, the route search processing unit 22 calculates the optimum travel route to the destination using the own vehicle position as the departure point by the route search processing (step 206). Next, a route guidance operation along the calculated guidance route is started (step 207). Specifically, the guidance route drawn by the guidance route drawing unit 24 is displayed on a map image, or an audio signal such as an intersection guidance generated by the voice guidance unit 26 is output from the audio unit 7 to guide the route. Operation is performed.

  In parallel with this route guidance operation, the stop determination unit 46 determines whether or not the vehicle has stopped at the temporarily registered point (step 208). If the vehicle does not stop, a negative determination is made, and the passage determination unit 42 determines whether or not the vehicle has passed the temporarily registered point (step 209). If not, a negative determination is made, and the process returns to step 208 to repeat the determination of whether or not there is a stop at the temporary registration point. If the vehicle passes through the temporarily registered point, an affirmative determination is made in the determination in step 209, and the cancellation processing unit 44 performs a process of canceling the temporary registration corresponding to the passed point (step 210).

  If the vehicle stops at the temporarily registered point, an affirmative determination is made in the determination of step 208. Next, the main registration processing unit 48 generates a main registration menu image, and the display processing unit 60 The registration menu image is displayed on the screen of the display device 6 (step 211). Thereafter, the user operates the remote control unit 4 to input information necessary for editing the place name and the like, and the main registration processing by the main registration processing unit 48 is performed (step 212). The main registration processing unit 48 determines whether or not input of necessary information has been completed (step 213). If the input has not ended, a negative determination is made and the main registration processing at step 212 is continued. In addition, when the input of necessary information is completed and an operation for instructing that is performed by the user, an affirmative determination is made in the determination in step 213, and step 208 is performed in order to perform the same processing for other temporarily registered points. The process is continued after returning to.

  In this way, in the navigation device of this embodiment, since the temporary registration at this point is canceled when passing without stopping after the point designated at the time of passing and temporarily registered, without doing anything after the designation. It is possible to avoid an increase in the number of neglected points, and to prevent deterioration in operability.

  In addition, when the vehicle stops at the tentatively registered point, the main registration corresponding to this point will be performed. This makes it possible to perform the main registration and to improve the operability by reducing the number of target points for the main registration.

  Also, when the vehicle stops after temporary registration, the route search process is performed using the temporarily registered point as a transit point or destination to determine the travel route. It is possible to reconfirm the existence of the tentatively registered point and to guide traveling to that point.

  In addition, when the main registration is not performed within the predetermined period for the point where the temporary registration has been performed, the temporary registration at this point is canceled by canceling the temporary registration at this point. Temporary registration can be canceled for a point that has been lost, and the effort to cancel temporary registration for a point that has lost interest can be reduced.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention. In the above-described embodiment, the point at the time of temporary registration is specified using the remote control unit 4, but an input device made up of a touch panel is attached to the display device 6, and a part of the screen is displayed with a user's finger or the like. You may make it designate the point of temporary registration by pointing directly.

  Further, in the above-described embodiment, the main registration process is performed when the engine rotation is temporarily stopped and the accessory switch is turned on again after the temporary registration. However, the stop determination criterion for starting the main registration is appropriately changed. Can do. For example, the main registration process may be performed regardless of the engine rotation state when the vehicle is stopped for a predetermined time. Alternatively, when a driver's main registration instruction is given, the main registration process may be performed regardless of the stop condition of the vehicle.

It is a figure which shows the structure of the navigation apparatus of one Embodiment. It is a flowchart which shows the operation | movement procedure of the temporary registration performed while driving | running | working a vehicle. It is a flowchart which shows the operation | movement procedure which cancels main registration or temporary registration with respect to the temporarily registered point.
