  Hereinafter, the outline of the parking position notification system of the first embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an outline of a parking position notification system 100 according to the present embodiment. As shown in FIG. 1, the parking position notification system 100 of the present embodiment is the property of the automobile 1, the parking position notification device 31 placed and installed in the automobile 1, and the user of the automobile 1. This is a configuration including the mobile terminal 2 in the automobile 1. The automobile 1 includes at least a drive recorder 11 and a gear lever 13. The drive recorder 11 may be replaced with a function of acquiring a front image in the car navigation system. The gear lever 13 may be replaced with another device that can be used for detecting the backward movement of the automobile 1 such as an accelerometer. Note that the parking position notification device 31 can communicate with the mobile terminal 2 by short-range wireless communication, and can perform data communication with other devices when necessary.

  With reference to FIG. 2, the structure of each apparatus which comprises the parking position alerting | reporting system 100 of a present Example is demonstrated. FIG. 2 is a block diagram illustrating the configuration of each device of the parking position notification system 100 according to the present embodiment. As illustrated in FIG. 2, the parking position notification device 31 includes a reverse detection unit 311, a video acquisition unit 312, and a data transmission unit 313, and the video acquisition unit 312 includes a front video acquisition unit 3121 and a front video temporary storage. Part 3122. The portable terminal 2 includes a data receiving unit 21 and a display unit 22.

  Hereinafter, with reference to FIG. 3, operation | movement of each apparatus which comprises the parking position alerting | reporting system 100 of a present Example is demonstrated. FIG. 3 is a sequence diagram showing the operation of each device of the parking position notification system 100 of the present embodiment. First, the reverse detection unit 311 detects the reverse of the vehicle (automobile 1) (S311A). For example, the reverse detection unit 311 detects reverse of the vehicle (automobile 1) by detecting whether or not the reverse gear (reverse gear) is selected by the gear lever 13 (S311A). For example, the gear lever 13 may be provided with a selection gear notification function (for example, by short-range wireless communication), or the reverse detection unit 311 captures the gear lever 13 and detects the state of the gear lever from the captured image. Thus, whether or not the reverse gear (reverse gear) is selected by the gear lever 13 may be detected. The reverse detection unit 311 may detect reverse of the vehicle (automobile 1) from other than the gear lever 311. For example, the reverse detection unit 311 may detect the reverse of the vehicle (automobile 1) from the direction of the acceleration vector measured by the accelerometer 14 (S311A). The accelerometer 14 may be built in the parking position notification device 31, or the accelerometer 14 may be an in-vehicle device, and data may be transmitted and received with the parking position notification device 31 by wireless communication. Further, the reverse detection unit 311 may detect the reverse of the vehicle (automobile 1) using, for example, an OBD steering angle signal, an engine stop signal (which can be considered to detect the end of reverse) (S311A). ). When the reverse detection unit 311 detects the reverse of the vehicle (the automobile 1), the reverse detection unit 311 outputs a signal notifying the front image acquisition unit 3121 of this (S311B). It is assumed that this signal includes the time when the vehicle (automobile 1) is detected to move backward.

  The forward image acquisition unit 3121 is an image of a predetermined time interval based on the time when the vehicle (automobile 1) is detected to reverse when the signal including the above notification is received, and the vehicle (automobile 1) A front image, which is an image in the forward direction, is acquired (S3121A). Specifically, when the front video acquisition unit 3121 receives a signal including the above-described notification, the forward video acquisition unit 3121 passes the predetermined time (for example, up to 3 minutes before) from the time when the backward movement of the vehicle (the automobile 1) is detected. Then, the front video of the vehicle (automobile 1) is taken as the front video, and the front video is acquired from the drive recorder 11 (S3121A). The front video acquisition unit 3121 temporarily stores the acquired front video in the front video temporary storage unit 3122 (S3121B).

  The data transmission unit 313 transmits the front video temporarily stored in the front video temporary storage unit 3122 by short-range wireless communication (S313). “Sending” in step S313 is a concept similar to “broadcasting” because it is executed without specifying a partner device, and is called broadcast, multicast, anycast, or advertisement.

  The data receiving unit 21 of the portable terminal 2 has a short-range wireless communication function, and receives the front image transmitted by the data transmitting unit 313 (S21). The display unit 22 displays the received front video (S22). The portable terminal 2 stores the received front video. The display unit 22 displays the stored front video as needed according to the user's operation.

  According to the parking position notification system 100 of the present embodiment, the parking position notification device 31 detects the backward movement of the vehicle (the automobile 1) from the state of the gear lever 13, and the predetermined time from the detected time with reference to the detected time. The video of the drive recorder 11 over time is acquired as a front video, the front video is distributed by the short-range wireless communication function, and is received and displayed by the mobile terminal 2, so that the vehicle (automobile 1) moves backward to the user. The scenery in front of the vehicle (automobile 1) immediately before the operation can be notified.

  When the vehicle (the automobile 1) moves backward, the vehicle (the automobile 1) is likely to be in a state immediately before entering the parking space in the parking lot. Of course, it is not uncommon for the vehicle (car 1) to move backwards in a place unrelated to the parking lot, but even if a video of such an unrelated scene is recorded as a front video, Is immediately recognizable. Therefore, the user can check the state (scenery) in front of the vehicle just before entering the parking space by checking one or at most two of the most recent forward images. Thus, the parking position of the vehicle (car 1) can be roughly known.
