FIG. 3 is a flowchart of route guidance processing according to the embodiment (steps are abbreviated as “S” in the description of each processing below). FIG. 4 is a flowchart of the route guidance process following FIG. This route guidance processing is performed by using the in-vehicle device 20 to specify the information for identifying the getting-off point when the in-vehicle device 20 acquires information for specifying the getting-off point of the owner of the mobile terminal 10 from the mobile terminal 10. This is a process in which guidance for the second route is performed after the guidance for the first route is performed based on the first route. For example, the processing is started after the mobile terminal 10 and the in-vehicle device 20 are powered on. As a premise of this route guidance processing, it is assumed that one owner of the mobile terminal 10 and one driver are on the vehicle.

  When the route guidance process is activated, as shown in FIGS. 3 and 4, the control unit 16 of the mobile terminal 10 performs the processes from SA1 to SA3 to guide the third route to the owner of the mobile terminal 10. I do.

  First, the route search unit 16a of the mobile terminal 10 receives the predetermined operation via the operation unit 13 by the owner of the mobile terminal 10, so that the departure point, the destination, and the getting-off point of the owner of the mobile terminal 10 are determined. Wait until it is set (SA1, No).

  Here, the setting of the departure place is not limited to being set when a predetermined operation is received via the operation unit 13 by the holder of the mobile terminal 10, and is acquired by the terminal current position acquisition unit 16b, for example. The current position of the mobile terminal 10 may be set as the departure place. Further, the setting of the alighting point is not limited to being set by a predetermined operation being accepted by the holder of the mobile terminal 10 via the operation unit 13, but for example, the departure place and the purpose set in SA1 Based on the location and map information stored in the map information DB 17a (particularly, feature data, etc.), a public transportation station or the like in the area from the departure point to the destination is automatically set as the drop-off point. May be.

  When the departure point, the destination, and the getting-off point for the owner of the mobile terminal 10 are set (SA1, Yes), the route search unit 16a of the mobile terminal 10 uses the known route search method to change to SA1. The third route from the departure point to the destination via the disembarking point is searched based on the starting point, the destination and the disembarking point set in the above and the map information stored in the map information DB 17a ( SA2). Then, the guidance unit 16d of the mobile terminal 10 starts guidance for the searched third route via the display 14 (SA3).

  For the guidance of the third route, specifically, the third route is superimposed on the map of the display 14, and the current location of the mobile terminal 10 acquired by the terminal current location acquisition unit 16b of the mobile terminal 10 is displayed. Are also displayed in superposition (the same applies to the guidance of the third route of SA11 described later, the guidance of the first route of SB6 described later, and the guidance of the second route of SB13). Here, regarding the acquisition of the current position of the mobile terminal 10 by the terminal current position acquisition unit 16b, specifically, the current position of the mobile terminal 10 is acquired at predetermined time intervals (for example, 1 sec) and acquired. Between the current position of the mobile terminal 10 and the detection time acquired from an internal clock (not shown) provided in the control unit 16 of the mobile terminal 10 and the current position of the mobile terminal 10 is detected. Is recorded in the data recording unit 17 of the mobile terminal 10. Such a series of processes is continuously performed from the process of SA3 until the route guidance process is completed.

  Next, the control unit of the mobile terminal 10 is configured so that data can be shared between the mobile terminal 10 and the in-vehicle device 20 by performing pairing processing on the mobile terminal 10 and the in-vehicle device 20. 16 performs processing from SA4 to SA6, and the control unit 27 of the in-vehicle device 20 performs processing from SB1 to SB3. Here, the “pairing process” is a process for establishing communication between the mobile terminal 10 and the in-vehicle device 20 in order to enable short-range communication between the mobile terminal 10 and the in-vehicle device 20. Means.

  First, the pairing detection unit 16c of the mobile terminal 10 stands by until the owner of the mobile terminal 10 performs a predetermined operation via the operation unit 13 to accept the start of the pairing process (SA4, No). . In addition, the pairing detection unit 27d of the in-vehicle device 20 waits until the start of the pairing process is accepted when a predetermined operation is performed by the driver of the vehicle (or the passenger of the vehicle) via the operation unit 24. (SB1, No). When the start of the pairing process is accepted (SA4, Yes, SB1, Yes), the pairing detection unit 16c of the mobile terminal 10 and the pairing detection unit 27d of the in-vehicle device 20 execute the pairing process ( SA5, SB2). Here, regarding the acceptance of the pairing process, specifically, the in-vehicle device 20 performs an operation for setting to a state in which the pairing process is possible, and then the mobile terminal 10 performs the pairing process. By performing an operation of selecting an in-vehicle device 20 to be subjected to pairing processing or an operation of inputting a password such as a PIN code in a state where a device or the like in a possible state is displayed on the display 14, Pairing processing is accepted.

  Next, the control unit 16 of the mobile terminal 10 and the control unit 27 of the in-vehicle device 20 start data sharing processing (SA6, SB3).

  Here, for this data sharing processing, specifically, the control unit 27 of the in-vehicle device 20 detects and detects the current position of the mobile terminal 10 recorded in the data recording unit 17 of the mobile terminal 10 via the communication unit 23. The time is acquired, and the acquired current position and detection time of the mobile terminal 10 are associated with each other and recorded in the data recording unit 28. This SA6 process is executed from SA7 to SA9, and this SB3 process is executed from SB4 to SB10.

  Next, in order to guide the first route to the driver of the host vehicle and the passengers of the host vehicle, the control unit 16 of the mobile terminal 10 performs the processes of SA7 and SA8 and the control unit 27 of the in-vehicle device 20. Performs processing from SB4 to SB6.

  First, the control unit 16 of the mobile terminal 10 transmits a signal including the getting-off point set in SA1 to the in-vehicle device 20 via the communication unit 12 (SA7).

  Next, the control unit 27 of the in-vehicle device 20 stands by until a signal including the disembarking point transmitted from the mobile terminal 10 is received via the communication unit 23 (SB4, No).

  And when the signal containing an alighting point is received (SB4, Yes), the route search part 27a of the vehicle-mounted apparatus 20 is the said received from the vehicle-mounted apparatus 20 via the communication part 23 using the well-known route search method. From the current location of the host vehicle based on the drop-off point included in the signal, the current location of the host vehicle acquired by the current vehicle location acquisition unit 27b at that time, and the map information stored in the map information DB 28a. The first route to the disembarking point is searched (SB5). And the guide part 27f of the vehicle-mounted apparatus 20 starts the guidance of this searched 1st route via the display 25 (SB6).

  Further, after the processing of SA7, the guidance unit 16d of the mobile terminal 10 stops the guidance of the third route on the assumption that the guidance of the first route in the in-vehicle device 20 is started by performing this processing ( SA8).

  Next, after the owner of the mobile terminal 10 gets off from the own vehicle at the getting-off point and its vicinity, the second route is guided to the driver of the own vehicle, and the third person is given to the owner of the mobile terminal 10. In order to guide the route, the control unit 16 of the mobile terminal 10 performs processing from SA9 to SA11, and the control unit 27 of the in-vehicle device 20 performs processing from SB7 to SB13.

  First, the getting-off detection unit 27e of the in-vehicle device 20 determines whether or not the owner of the mobile terminal 10 has got off the own vehicle (SB7). Here, with regard to the determination of getting off for the owner of the mobile terminal 10, for example, whether or not the short-distance wireless communication between the mobile terminal 10 and the in-vehicle device 20 is disconnected, the current position of the mobile terminal 10 and the current position of the in-vehicle device 20 Any one of a distance between the vehicle, a change in the vehicle speed of the own vehicle, a change in the seat weight of the own vehicle, a gear operation state of the own vehicle, a change in the reverse signal of the own vehicle, and a blinking state of the hazard of the own vehicle. However, in the embodiment, the distance between the current position of the mobile terminal 10 and the current position of the in-vehicle device 20 and the change in the vehicle speed of the host vehicle are considered. It is assumed that the determination is based on the above.

  Specifically, first, the getting-off detection unit 27e of the in-vehicle device 20 determines that the vehicle speed of the host vehicle is zero or more based on the vehicle speed of the host vehicle acquired by the vehicle speed acquisition unit 27c at that time. It is determined whether or not (for example, 10 sec or longer). Here, when it is determined that the state in which the vehicle speed of the host vehicle is zero has not continued for a predetermined time or more, it is determined that the owner of the mobile terminal 10 has not got off the host vehicle. On the other hand, when it is determined that the vehicle speed of the host vehicle is maintained for a predetermined time or longer, the current position of the host vehicle acquired by the vehicle current position acquisition unit 27b at that time, and Based on the current position of the mobile terminal 10 acquired by the terminal current position acquisition unit 16b and the map information stored in the map information DB 28a, the current position of the mobile terminal 10 is within the peripheral region of the current position of the host vehicle. It is determined whether or not it is located (for example, within a radius of 100 m from the current position of the host vehicle). When it is determined that the current position of the mobile terminal 10 is located within the peripheral region of the current position of the host vehicle, it is determined that the owner of the mobile terminal 10 has not got off the host vehicle, and the current position of the mobile terminal 10 is determined. When it is determined that the position is not within the peripheral region of the current position of the host vehicle, it is determined that the owner of the mobile terminal 10 is getting off the host vehicle. In this case, the acquisition of the current position of the mobile terminal 10 when the communication state of the short-range communication between the mobile terminal 10 and the in-vehicle device 20 is unstable or incapable of communication is, for example, the mobile terminal 10 The control unit 16 transmits the current position of the mobile terminal 10 to the server (not shown) on the network 2 via the network 2 by the communication unit 12, and the getting-off detection unit 27 e of the in-vehicle device 20 transmits The current position of the mobile terminal 10 may be acquired by receiving the current position of the mobile terminal 10 from a server on the network 2.

  As described above, the getting-off detection unit 27e of the in-vehicle device 20 detects that the owner of the mobile terminal 10 gets out of the own vehicle based on the vehicle speed and the current position of the mobile terminal 10. Since it is possible to detect the getting-off in consideration of the moving state of the own vehicle, the detection accuracy of getting-off can be improved.

  Here, when it is determined that the owner of the mobile terminal 10 has not got off the host vehicle (SB7, No), the getting-off detection unit 27e of the in-vehicle device 20 indicates that the owner of the mobile terminal 10 has got off the vehicle. Until the determination is made, the process of SB7 is repeated at predetermined time intervals (for example, every 5 seconds).

  On the other hand, when it is determined that the owner of the mobile terminal 10 has got off the host vehicle (SB7, Yes), the guide unit 27f of the in-vehicle device 20 acquires the host vehicle acquired by the vehicle current position acquisition unit 27b at that time. The current position of the host vehicle is within a predetermined distance (for example, within 300 m) from the departure point based on the current location of the vehicle, the departure point received at SB4, and the map information stored in the map information DB 28a. Whether or not (SB8).

  Here, when it is determined that the current position of the host vehicle is not within a predetermined distance from the getting-off point (SB8, No), the point where the owner of the mobile terminal 10 is located in a region other than the region including the getting-off point and its surroundings However, there is no need to guide the second route to the driver of the own vehicle, but there is a need to guide the third route to the owner of the mobile terminal 10. is there. Accordingly, the guide unit 27f of the in-vehicle device 20 ends the route guidance process, and the control unit 16 of the mobile terminal 10 proceeds to SA10 described later. If the current position of the host vehicle is not on the third route when moving to SA10 described later, the route search unit 16a of the mobile terminal 10 is set in SA1 in SA11 described later.
