The content of the operation is the mode of the navigation processing device 200 switched by the slide operation of the mode switching button 101 or the pressing of the operation execution button 103. When the mode switching button 101 is slid, the operation content determination unit 203 stores the setting of the mode switching button 101. When the operation detection unit 201 detects that the operation execution button 103 is pressed, the control unit 205 controls the operation according to the mode of the navigation processing device 200 set by the mode switching button 101 to be performed.

  The positioning unit 207 operates according to an instruction from the control unit 205 when the setting of the mode switching button 101 when the operation execution button 103 is pressed is “record” or “guidance”. Positioning unit 207 includes a receiving device (not shown) that receives radio waves from GPS satellites. The positioning unit 207 measures the current position of the key 100 by receiving radio waves from GPS satellites. Information (current position information) measured by the positioning unit 207 is represented by latitude, longitude, and height.

  When the setting of the mode switching button 101 is “record”, the positioning unit 207 records the current position information in the memory 209 as parking position information. The memory 209 stores the current position information measured by the positioning unit 207 as parking position information. When the positioning unit 207 records the current position information in the memory 209, the positioning unit 207 notifies the control unit 205 to that effect. When the control unit 205 receives the notification, the control unit 205 instructs the audio output processing unit 219 to output a voice message indicating that the current position information is recorded as the parking position information of the vehicle corresponding to the key 100 from the speaker 105. On the other hand, when the setting of the mode switching button 101 is “guidance”, the positioning unit 207 inputs the current position information to the route guidance processing unit 213.

In order to perform route guidance, the route guidance processing unit 213 acquires parking position information stored in the memory 209. Further, the route guidance processing unit 213 identifies the direction from the current position to the parking position. Further, the route guidance processing unit 213 instructs the map data processing unit 215 to acquire map information of an area including the current position and the parking position measured by the positioning unit 207. The route guidance processing unit 213 searches for a route from the current position to the parking position based on the map information obtained from the map data processing unit 215, the current position and the parking position, and provides route guidance from the current position to the parking position. Process to do with voice. For example, the route guidance processing unit 213 provides guidance according to the route after guiding the distance and direction from the current position to the parking position by voice. At this time, the route guidance processing unit 213 also guides the direction in which the user should proceed according to the searched route and the determination result by the direction determining unit 211. A direction is represented by the front-rear left-right direction, the diagonal direction, and the up-down direction.

The following is an example of audio output from the speaker 105 during route guidance.
“To the destination, it is 700m diagonally forward right.”
"After going straight 100m, turn right."
"Please go straight."
"Please turn right."
"Turn right after 5m."
“Turn right at the intersection.”
"To the destination, it is 50m diagonally left front."
“It is 10m leftward to the destination.”
"It is 5m forward to the destination."
“To the destination, it is 50m ahead diagonally to the left, upward. The floor may be different.”
“To the destination, it is 50m behind. Please turn back.”
“You have arrived at your destination.”

  The map data processing unit 215 reads the map information of the area instructed from the route guidance processing unit 213 from the map information DB 217, and performs data processing in a form that can be processed by the route guidance processing unit 213. The map information DB 217 is a database in which map information is stored. The voice output processing unit 219 performs processing to output voice route guidance obtained as a result of processing by the route guidance processing unit 213 from the speaker 105. In addition, the voice output processing unit 219 performs processing to output a voice message regarding each operation status instructed from the control unit 205 from the speaker 105.

  Hereinafter, the operation of the navigation processing apparatus 200 according to the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart showing the operation of the navigation processing apparatus 200 shown in FIG. The operation detection unit 201 of the navigation processing device 200 determines whether or not the operation execution button 103 has been operated (step S101), and when the operation execution button 103 has been operated, the process proceeds to step S103.

  In step S103, the control unit 205 determines the mode set by the mode switching button 101. If “record”, the control unit 205 proceeds to step S105. If “guide”, the process proceeds to step S111. If “stop”, the control unit 205 proceeds to step S111. Proceed to step S131. For example, after parking in a large parking lot or the like and getting off, the user slides the mode switching button 101 to “MEMORY” to store the stop position of the own vehicle, and presses the operation execution button 103. move on.

  In step S105 performed when the mode is “recording”, the positioning unit 207 measures the current position. Next, the positioning unit 207 records information on the current position measured in the memory 209 as parking position information (step S107). Next, the control unit 205 instructs the audio output processing unit 219 to output from the speaker 105 a voice message that the current position information is recorded in the memory 209 as the parking position information of the vehicle. Is output (step S109). After the voice message is output from the speaker 105, the user may slide the mode switching button 101 to the “stop” position. If the mode switching button 101 is set to the “stop” position, the parking position information recorded in the memory 209 is not overwritten even if the operation execution button 103 is pressed by mistake.

  In step S <b> 111 performed when the mode is “guidance”, the route guidance processing unit 213 acquires the parking position information stored in the memory 209. Next, the positioning unit 207 measures the current position, and the route guidance processing unit 213 specifies the direction from the current position to the parking position (step S113). Next, the route guidance processing unit 213 instructs the map data processing unit 215 to acquire map information of an area including the current position and the parking position (step S115). Next, the route guidance processing unit 213 searches for a route from the current position to the parking position (step S117).

  Next, the route guidance processing unit 213 instructs the voice output processing unit 219 to output from the speaker 105 voice messages for completion of route search and start of route guidance, and the voice message is output from the speaker 105 ( Step S119). Next, the route guidance processing unit 213 performs processing to perform route guidance by voice output from the speaker 105 (step S121). Next, when the route guidance processing is completed, the route guidance processing unit 213 outputs a voice message indicating that the route guidance is to be terminated (for example, “voice guidance is terminated”) from the speaker 105. The voice message is output from the speaker 105 (step S123).

  In step S131 performed when the mode is “stop”, the control unit 205 determines whether the route guidance processing unit 213 is in the middle of performing route guidance (step S131) and executes route guidance. If so, the process proceeds to step S133. In step S133, the control unit 205 instructs the route guidance processing unit 213 to stop the route guidance processing. Next, the control unit 205 instructs the voice output processing unit 219 to output from the speaker 105 a voice message indicating that the route guidance has been canceled (for example, “voice guidance is canceled.”). A voice message is output (step S135).

  As described above, the operation for registering the current position as the parking position performed on the key 100 provided with the navigation processing device 200 of the present embodiment is the operation for starting the route guidance to the parking position. Also, it can be performed only by sliding the mode switching button 101 and pressing the operation execution button 103. Even if the navigation processing apparatus 200 does not include a communication unit, route guidance to the parking position can be performed. Furthermore, since the route guidance is performed by voice, a display is not necessary. Therefore, the configuration of the navigation processing device can be simplified.

  The navigation processing apparatus according to the present invention is useful as a navigation processing apparatus or the like for performing route guidance to a preset position.
