Also, the schedule information transmission function of the terminal control device 210 acquires the user schedule information stored in the terminal storage device 230, and sends the acquired user schedule information to the information center 300 via the terminal communication device 240. Send.

  Next, the information center 300 will be described. The information center 300 is installed outside the vehicle, collects the user's schedule information from the user's information terminal 200, and based on the collected user's schedule information, provides information on the parking lot in consideration of the user's schedule. To provide. Specifically, as shown in FIG. 1, the information center 300 includes a center control device 310, a center communication device 320, a schedule database 330, and a parking lot information database 340.

  Center communication device 320 communicates with in-vehicle device 100 and information terminal 200. Specifically, the center communication device 320 receives the route information transmitted from the in-vehicle device 100, and transmits the received route information to the center control device 310. Further, the center communication device 320 receives the schedule information transmitted from the information terminal 200 and transmits the received schedule information to the center control device 310. Furthermore, the center communication device 320 transmits the parking lot information transmitted from the center control device 310 to the in-vehicle device 100.

  The schedule database 330 stores user schedule information received from the information terminal 200. Here, FIG. 2 is a diagram illustrating an example of schedule information stored in the schedule database 330. As shown in FIG. 2, the schedule information stored in the schedule database 330 includes information such as the user name, the planned location where the user is scheduled, the scheduled start time of the user, and the required time for the schedule.

  The parking lot information database 340 stores information on parking lots installed in various places. Here, FIG. 3 is a diagram illustrating an example of parking lot information stored in the parking lot information database 340. As shown in FIG. 3, the parking lot information stored in the parking lot information database 340 includes information such as the name of the parking lot, the location of the parking lot, the basic parking fee, and the upper limit fee. The parking lot information stored in the parking lot information database 340 is not limited to the example shown in FIG. 3. For example, the parking lot information database 340 is an indoor parking lot, has a roof, has a large parking space, or has a charging stand. Such information may be stored.

  The center control device 310 includes a CPU, a ROM, and a RAM, similarly to the in-vehicle control device 110 and the terminal control device 210. And the center control apparatus 310 performs the program memorize | stored in ROM by CPU, a schedule information acquisition function, a route information acquisition function, a travel time prediction function, a margin time calculation function, and a parking lot search function And a parking lot information transmission function. Hereinafter, each function realized by the center control device 310 will be described.

  The schedule information acquisition function of the center control device 310 acquires user schedule information from the user information terminal 200 via the center communication device 340. Note that the user's schedule information acquired by the schedule information acquisition function is stored in the schedule database 330.

  The route information acquisition function of the center control device 310 acquires the route information transmitted from the in-vehicle device 100 via the center communication device 320. Specifically, the route information acquisition function acquires information including the destination, current position, traffic information, and scheduled travel route of the vehicle on which the in-vehicle device 100 is mounted from the in-vehicle device 100 as route information.

  The travel time prediction function of the center control device 310 predicts the travel time from the current position P0 of the vehicle to the next planned planned location P1 as the first travel time T1. For example, the travel time prediction function is based on the current location P0 of the user received from the in-vehicle device 100, the destination of the user (the next planned location P1), and the planned travel route, and the next planned schedule from the current location P0. The road link of the road on which the vehicle travels up to the place P1 is specified. The travel time prediction function is the next schedule from the current position P0 based on information such as the travel time of the road link, the distance, the road type, and the presence / absence of a traffic light, which is also included in the traffic information received from the in-vehicle device 100. The travel time to the planned location P1 is predicted as the first travel time T1. Thus, prediction accuracy of the 1st movement time T1 can be improved by predicting 1st movement time T1 using traffic information.

  The travel time prediction function predicts the travel time from the next scheduled place P1 to the next scheduled place P2 as the second travel time T2. For example, the travel time prediction function is the second scheduled schedule among the user's destination received from the in-vehicle device 100 (the next scheduled scheduled place P1) and the user's schedule information stored in the schedule database 330. From the in-vehicle device 100 by searching for the planned travel route from the next planned planned location P1 to the next planned planned location P2 based on the location P2, and identifying the road link of the searched planned travel route. Based on the received traffic information, the travel time from the next planned planned location P1 to the next planned planned location P2 is predicted as the second travel time.

  Next, the margin time calculation function of the center controller 310 will be described. The allowance time calculation function calculates the allowance time that can be used for the user to move from the parking lot around the next scheduled place P1 to the next scheduled place P1 as the first allowance time. Specifically, the allowance time calculation function is based on the current time t0 and the first travel time T1 from the current position P0 predicted by the travel time prediction function to the next planned place P1, and the next time The estimated arrival time t1 arriving at the place P1 is predicted. The margin time calculation function acquires the scheduled start time t2 at the next planned location P1 based on the user's schedule information acquired by the schedule information acquisition function. The allowance time calculation function calculates the difference (t2−t1) between the scheduled arrival time t1 when the vehicle arrives at the next planned location P1 and the planned start time t2 at the next planned location P1. It is calculated as the first margin time that can be used to move from the parking lot around the place P1 to the next planned place P1.

  For example, in the example shown in FIG. 2, when providing parking information to the user A, the current time is “11:00” and the first travel time from the current position P0 to the next scheduled place P1 Is predicted to be “40 minutes”, the margin time calculation function calculates the estimated arrival time t1 at which the vehicle arrives at the next scheduled location P1 as “11:40”. On the other hand, the margin time calculation function specifies the scheduled start time t2 at the next planned location P1 as “12:00” from the schedule information shown in FIG. The margin time calculation function is “11:40” which is the scheduled arrival time t1 when the vehicle arrives at the next scheduled place P1, and “12:00” which is the scheduled start time t2 at the next scheduled place P1. , That is, “20 minutes”, can be calculated as the first margin time that can be used for the user to move from the parking lot around the next planned location P1 to the next planned location P1.

  Furthermore, the margin time calculation function calculates a margin time that can be used for the user to return from the next planned location P1 to the parking lot around the planned location P1 as the second margin time. Specifically, the margin time calculation function calculates the next schedule end time t3 from the start time and the required time of the next schedule in the schedule information, and predicts the next schedule end time t3 and the travel time. Based on the second travel time T2 from the next planned location P1 predicted by the function to the next planned location P2, the estimated arrival time t4 at which the vehicle arrives at the planned location P2 is predicted. Further, the allowance time calculation function acquires the scheduled start time t5 at the second scheduled planned location P2 based on the user's schedule information acquired by the schedule information acquiring function. The allowance time calculation function calculates the difference (t5−t4) between the scheduled arrival time t4 when the vehicle arrives at the second scheduled planned location P2 and the scheduled start time t5 at the planned location P2 by the user It is calculated as a second margin time that can be used to move from the planned location P1 to a parking lot around the planned location P1.

  For example, in the example shown in FIG. 2, when providing parking information to the user A, it is possible to specify from the schedule information that the schedule at the next planned location P1 ends at “14:00”. Therefore, when the second travel time T2 from the next planned location P1 to the next planned location P2 is predicted to be “50 minutes”, the allowance time calculation function causes the vehicle to arrive at the planned location P2. The estimated arrival time t4 is calculated as “14:50”. On the other hand, the margin time calculation function can identify the second scheduled start time t5 as “15:00” from the schedule information shown in FIG. The allowance time calculation function is “14:50”, which is the scheduled arrival time t4 when the vehicle arrives at the second planned location P2, and “15:00”, which is the planned start time t5 at the second planned location P2. "10 minutes" can be calculated as the second margin time that can be used for the user to move from the next planned location P1 to the parking lot around the planned location P1.

  Further, the allowance time calculation function includes a first allowance time that the user can use to move from the parking lot around the next scheduled place P1 to the next scheduled place P1, and the user from the next scheduled place P1 to the scheduled place. Of the second margins that can be used to move to the parking lot around the ground P1, the shorter time is calculated as the reference margin time. For example, in the example shown in FIG. 2, since the first margin time is “20 minutes” and the second margin time is “10 minutes”, the second margin time “10 minutes” is calculated as the reference margin time. Is done.

  Next, the parking lot search function of the center control device 310 will be described. The parking lot search function searches for a parking lot where the user can move within the reference margin time from the next scheduled place P1 based on the reference margin time calculated by the margin time calculation function. Specifically, the parking lot search function first determines the range of the moving distance within the reference margin time on foot from the next scheduled place P1 as the parking lot search range. For example, when the reference margin time calculated by the margin time calculation function is 10 minutes and the average walking speed of a person is 80 m / min, the range for searching for a parking lot is as follows: The parking lot search function calculates a range of 10 × 80 = 800 (m) from the next planned location P1 as a search range.

  And a parking lot search function searches a parking lot within a search range. Even if the user moves on foot between the next scheduled place P1 and the parking lot, the user can enter the parking area within the search range that can move within the reference margin time from the next scheduled place P1. The schedule at the next planned location P1 can be made in time, and after the schedule at the next planned location P1 is completed, the vehicle has moved on foot from the next planned location P1 to a parking lot around the planned location P1. Even in this case, it is possible to meet the schedule at the next scheduled place P2.

  Furthermore, the parking lot search function determines one parking lot according to a predetermined condition as a parking lot for providing information to the user from a plurality of parking lots searched in the search range. For example, the parking lot search function determines a parking lot with the lowest parking fee as a parking lot for providing information to the user from a plurality of parking lots searched within the search range.

  Here, a method for determining a parking lot with the lowest parking fee will be described. First, the parking lot search function calculates the scheduled required time at the next planned place P1 as the parking time for parking the vehicle in the parking lot from the user's schedule information acquired by the schedule information acquisition function. Then, the parking lot search function refers to the parking lot information database 340 and calculates the parking fee at each parking lot searched within the search range based on the calculated parking time.

  Here, FIG. 3 is a diagram illustrating an example of the parking lot information stored in the parking lot information database 340. As shown in FIG. 3, the parking lot information database 340 stores parking lot information including the name of the parking lot, the location of the parking lot, the basic parking fee, and the upper limit fee for each parking lot. For example, in the example shown in FIG. 3, the parking lot is located at north latitude XX ° XX'XX "and west longitude XX ° XXX's every 15 minutes from 8:00 to 22:00. There is a fee system in which 100 yen is charged and 100 yen is charged every 60 minutes from 22:00 to 8:00. If the parking time is 24 hours or less, 1000 yen is applied as the upper limit amount.

  And in the example shown in FIG. 3, there are three parking lots within the search range, XX parking lot, △△ parking lot, and XX parking lot, for 1 hour from 12:00 to 13:00, When the vehicle is parked, the parking fee is 400 yen for the XX parking lot and the Δ △ parking lot, but the parking fee is 300 yen for the XX parking lot. Therefore, the parking lot search function determines the XX parking lot with the lowest parking fee as a parking lot for providing information to the user. In the above example, when parking for 5 hours from 12 o'clock to 17 o'clock, the upper limit charge is applied at XX parking lot and △△ parking lot, and the parking fee is 1000 yen each. Although it is 1500 yen, since the upper limit charge is not set in the xx parking lot, the parking charge is 1500 yen. Therefore, the parking lot search function determines the parking lot with the lowest parking fee as a parking lot for providing parking information to the user.

  Next, the parking lot information transmission function of the center control device 310 will be described. The parking lot information transmission function transmits information on one parking lot determined to provide information to the user by the parking lot search function via the center communication device 220 to the in-vehicle device 100. Thereby, in the vehicle-mounted apparatus 100, the information of the parking lot suitable for a user's schedule will be provided to a user.

  Next, the information providing process according to the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing information providing processing according to the present embodiment. In the following, a description will be given of an example of providing a user with information on a parking lot with the lowest parking fee among the parking lots existing within the search range.

  In step S101, the in-vehicle device 100 acquires the route search information including the current position P0 of the vehicle, the destination (next planned location P1), and traffic information by the route search information acquisition function of the in-vehicle control device 110. . In step S102, the route search function of the in-vehicle control device 110 searches for the planned travel route from the current position P0 to the next planned planned location P1 based on the route search information acquired in step S101. . Then, the route search information acquired in step S101 and the information on the planned travel route acquired in step S102 are transmitted to the information center 300 via the in-vehicle communication device 120 of the in-vehicle device 100.

  In step S103, in the information center 300, the travel time T1 from the current position P0 to the next scheduled place P1 is predicted by the travel time prediction function of the center control device 310. In step S <b> 104, the schedule information of the user is acquired from the schedule database 330 by the schedule information acquisition function of the center control device 310. For example, in the example illustrated in FIG. 2, when providing parking information to the user A, the schedule information acquisition function acquires all schedule information of the user A from the schedule database 330. That is, in the example shown in FIG. 2, as schedule information of the user A, schedule information of a schedule starting from “March 3 12:00” (plan at the next planned place P1) and “March 3 The schedule information of the schedule starting from “15:00” (the schedule at the next next scheduled place P2) is acquired.

  Further, in step S105, the travel time prediction function of the center control device 310 searches for a planned travel route from the next planned location P1 to the next planned location (next planned next location) P2. . In step S106, the travel time prediction function predicts the travel time T2 from the next planned location P1 to the next planned location P2 based on the planned travel route to the planned location P2 searched in step S105. Done. When calculating the travel time T2 in step S106, if the latest traffic information is acquired while the vehicle is traveling, it is preferable to calculate the travel time T2 based on the latest traffic information. .

  In Step S107, the first allowance time, which is an allowance time that can be used for the user to move from the parking lot around the next scheduled place P1 to the next scheduled place P1, is calculated by the allowance time calculating function. . For example, in the example shown in FIG. 2, when providing parking information to the user A, the current time is “11:00”, and in step S103, from the current position P0 to the next scheduled place P1. When the first movement time is predicted to be “40 minutes”, the surplus time calculation function calculates the estimated arrival time t1 when the vehicle arrives at the next planned location P1 as “11:40”. At the same time, the schedule start time t2 at the next scheduled place P1 is specified as “12:00” from the schedule information shown in FIG. The margin time calculation function is “11:40” which is the scheduled arrival time t1 when the vehicle arrives at the next scheduled place P1, and “12:00” which is the scheduled start time t2 at the next scheduled place P1. , That is, “20 minutes”, is calculated as the first margin time that can be used for the user to move from the parking lot around the next planned location P1 to the next planned location P1.

  In Step S108, the margin time calculation function calculates a second margin time, which is a margin time that can be used by the user to return from the next planned location P1 to the parking lot around the planned location P1. . For example, in the example shown in FIG. 2, when providing parking information to the user A, the second travel time T2 from the next scheduled place P1 to the next scheduled place P2 is “50” in step S106. If it is predicted that the time is “minute”, the allowance time calculation function can identify from the schedule information of the user A that the schedule at the next planned location P1 ends at “14:00”, so that the vehicle is scheduled The scheduled arrival time t4 arriving at the place P2 is calculated as “14:50”, and the start time t5 of the second schedule is specified as “15:00” from the schedule information. The allowance time calculation function is “14:50”, which is the scheduled arrival time t4 when the vehicle arrives at the second planned location P2, and “15:00”, which is the planned start time t5 at the second planned location P2. "10 minutes" is calculated as the second margin time that can be used for the user to move from the next planned location P1 to the parking lot around the planned location P1.

  Furthermore, in step S109, the reference margin time is calculated by the margin time calculation function. For example, in the above example, the margin time calculation function has the first margin time “20 minutes” and the second margin time “10 minutes”. The shorter time “10 minutes” is calculated as the reference margin time.

  In step S110, the search range of the parking lot is determined by the parking lot search function of the control device 10 based on the reference margin time calculated in step S109. Specifically, the parking lot search function determines the range of the moving distance within the reference margin time on foot from the next planned place P1 as the parking lot search range. In step S111, the parking lot search function searches for a parking lot that exists within the search range determined in step S110.

  In step S112, the required time for the next scheduled place P1 is calculated as the parking time based on the user's schedule information acquired in step S104 by the parking lot search function. In step S113, for each parking lot searched in step S111, a parking fee is calculated when the vehicle is parked for the parking time calculated in step S112. Specifically, the parking lot search function calculates a parking fee according to the parking time and the parking time from the basic parking fee among the parking lot information stored in the parking lot information database 340. Furthermore, the parking lot search function calculates the parking fee in consideration of the upper limit fee.

  In step S114, the parking lot search function selects the parking lot with the cheapest parking fee from the parking lots existing in the search range based on the parking fee calculated in step S113. . In step S115, the parking lot information transmission function of the center control device 310 acquires the parking lot information selected in step S114 from the parking lot information database 340 of the information center 300, and the obtained parking lot information is obtained.
