Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration of a departure time guidance system according to Embodiment 1 of the present invention.
As shown in FIG. 1, the departure time guidance system includes an in-vehicle information device 1, a telematics server 2, and a mobile information terminal 3.
The in-vehicle information device 1 is mounted on a vehicle on which a user who receives departure time guidance is boarded, and acquires position information acquisition means 10 for acquiring the current position of the vehicle, time information acquisition means 11 for acquiring the current time, and various information for the user. Display device 12 for presenting information, communication means 13 for communicating with telematics server 2, and processing based on information obtained from position information acquisition means 10, time information acquisition means 11, communication means 13, etc. The information processing means 14 which performs is provided.

  The telematics server 2 includes a route point setting means 20 for a user who receives route guidance to a destination by the in-vehicle information device 1 to set a departure point, a transit point, and a destination, and the user wishes to arrive at the destination. A desired arrival time input means 21 for inputting a desired arrival time, a communication means 22 for communicating with the in-vehicle information device 1 and the mobile information terminal 3, and a route point setting means 20, a desired arrival time input means. 21 and information processing means 23 for performing processing based on information obtained from communication means 22 and the like.

  The mobile information terminal 3 communicates with the departure time notifying means 30 for notifying the user of the departure time by display, voice, vibration, etc., based on the departure time notification information received from the telematics server 2 and the telematics server 2. A communication unit 31 is provided, and an information processing unit 32 that performs processing based on information obtained from the departure time notification unit 30 and the communication unit 31 is provided. Here, the departure time notifying means 30 displays the departure time on the display means (not shown in FIG. 1) of the mobile information terminal 3, or the voice output means (not shown in FIG. 1) of the mobile information terminal 3, for example. ) To output the voice of the departure time, or the vibration means (not shown in FIG. 1) of the mobile information terminal 3 vibrates at the departure time, thereby notifying the user that the departure time has been reached. .

Next, the processing operation of the departure time guidance system of the present embodiment will be described with reference to FIG.
The telematics server 2 receives the departure point, waypoint, destination set by the user in the route point setting means 20, and the desired arrival time input in the desired arrival time input means 21 (step S1). Then, the information processing means 23 calculates a route to the destination based on the departure point, waypoint, and destination set by the user and the desired arrival time set by the user (step S2). After the route calculation, the information processing unit 23 transmits the calculated route information to the in-vehicle information device 1 via the communication unit 22 (step S3). Thereafter, the process proceeds and the telematics server 2 receives the estimated arrival time from the in-vehicle information device 1 (step S9).

The in-vehicle information device 1 receives route information from the telematics server 2 via the communication means 13 (step S4). The in-vehicle information device 1 uses the route information received by the information processing means 14 and the current position of the vehicle acquired by the position information acquisition means 10, traffic information acquired via the communication means 13, and the like for route guidance. The estimated arrival time at the destination is calculated based on the information (step S5).
Thereafter, the information processing means 14 transmits the estimated arrival time calculated in step S5 to the telematics server 2 at predetermined time intervals. At this time, the information processing means 14 determines whether or not the predetermined time has passed. If the transmission condition is satisfied (step S6, step S7), the estimated arrival time is transmitted to the telematics server 2 via the communication means 13 (step S8).

Note that the transmission condition determination in step S6 is performed for the purpose of preventing excessive communication with the telematics server 2, but in addition to the transmission condition determination whether or not a certain period of time has elapsed, a change in the moving speed of the in-vehicle information device 1 may occur. If it is larger, the estimated arrival time largely fluctuates in accordance with the change in the moving speed of the in-vehicle information device 1, and therefore the estimated arrival time in consideration of the movement status of the in-vehicle information device such as shortening the transmission interval for transmitting the estimated arrival time. May be transmitted to the telematics server 2.
If the transmission condition is not satisfied in step S7, the process returns to step S5 and the process is continued.
Thereafter, in step S8, when the in-vehicle information device 1 transmits the estimated arrival time to the server, the telematics server 2 receives the estimated arrival time via the communication unit 22 (step S9).

Next, the telematics server 2 receives the estimated arrival time transmitted from the in-vehicle information device 1, but the information processing means 23 has not received the estimated arrival time transmitted from the in-vehicle information device 1 at regular intervals. A determination is always made (step S10). Then, when the estimated arrival time is not received for a certain time, the information processing means 23 determines that the user of the in-vehicle information device 1 has stopped the vehicle, and calculates the difference between the desired arrival time and the estimated arrival time as the stayable time. (Step S11), a timer corresponding to the stayable time is started (Step S12).
If it is determined in step S10 that the expected arrival time is received within a certain time, the process returns to step S9 and the processing is continued.

After starting the timer in step S12, the information processing means 23 confirms whether or not the stayable time has elapsed (step S13). When the stayable time has elapsed, the departure time guidance information is immediately sent via the communication means 22 via e-mail. To the mobile information terminal 3 (step S14).
Although the mail transmission method is described here as the communication means, the communication means is not particularly limited. If the stayable time has not elapsed in the determination in step S13, the confirmation is continued until the stayable time has elapsed.

  Next, when the mobile information terminal 3 receives departure time guidance information from the telematics server 2 via the communication means 31 (step S15), the departure time notification means 30 provides the departure time guidance to the user (step S16).

As described above, according to the present embodiment, the telematics server 2 calculates the route information to the destination based on the departure point, waypoint, destination, and desired arrival time set or input by the user, The in-vehicle information device 1 calculates the estimated arrival time at the destination based on the route information calculated by the telematics server 2 and the current position of the vehicle, and transmits it to the telematics server 2. When the estimated arrival time is not transmitted, the difference between the desired arrival time and the estimated arrival time is calculated as the stayable time. If the stayable time has elapsed, this departure time guide information is transmitted to the mobile information terminal 3. be able to.
As a result, the departure time guidance system can be used without any special operation or burden on the user even when the user suddenly interrupts the movement due to a break or the like at any point. It is possible to realize departure time guidance at a sudden movement interruption point without requiring special components (devices, instruments, etc.) such as a secondary power source. Therefore, the user can avoid the situation where the desired arrival time is exceeded when the movement is suddenly interrupted, and the user can use meaningful time at the movement interruption point where the movement is suddenly interrupted. It becomes possible to support.

Embodiment 2. FIG.
