Abstract

By executing the program, the processor realizes an acquisition unit, a diagnosis unit, and a message application providing unit. The acquisition unit acquires the driving data of the watching target person from the vehicle. The diagnosis unit performs a driving diagnosis based on the driving data. The message application providing unit displays a message input by the watching target person and the watcher on the chat screen. The message application providing unit includes a display control unit and a message generation unit. The display control unit displays a message on the chat screen. After the notification message notifying that the result of the driving diagnosis has been generated is displayed on the chat screen, the message generation unit can generate a reaction message for the result of the driving diagnosis.

Claims (4)

1 . A driving diagnosis system comprising a processor and a storage medium, wherein: the processor is configured to execute a program stored in the storage medium to implement an acquisition unit configured to acquire driving data of a watching target person from a vehicle, a diagnosis unit configured to perform driving diagnosis based on the driving data, and a message application providing unit configured to display, on a chat screen, messages input by the watching target person and a watcher; the message application providing unit includes a display control unit configured to display messages on the chat screen, and a message generation unit configured to generate a reaction message to a result of the driving diagnosis after a notification message for notification that the result of the driving diagnosis has been generated is displayed on the chat screen; and the display control unit is configured to display the reaction message on the chat screen after a predetermined waiting period for waiting for input of a message by the watcher has elapsed from a point in time when the notification message was displayed on the chat screen.
2 . The driving diagnosis system according to claim 1 , wherein the message generation unit is configured to determine whether the reaction message is generable based on a frequency of input of the message by the watcher.
3 . The driving diagnosis system according to claim 1 , wherein the message generation unit is configured to transmit a safety check message after a predetermined observation period has elapsed from a point in time when a latest message was input by the watching target person.
4 . The driving diagnosis system according to claim 3 , wherein: the result of the driving diagnosis includes an evaluation of a cognitive function of the watching target person; and the predetermined observation period is determined based on the evaluation of the cognitive function.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims priority to Japanese Patent Application No. 2023-150682 filed on Sep. 19, 2023, incorporated herein by reference in its entirety. BACKGROUND 1. Technical Field The present specification discloses a driving diagnosis system. 2. Description of Related Art The behavior of a vehicle and a driving operation can be detected by providing a sensor in the vehicle. Details of driving can be evaluated based on detected data (driving data). For example, in Japanese Unexamined Patent Application Publication No. 2023-85100 (JP 2023-85100 A), a bonus is given when the result of driving diagnosis is good. This bonus is given to a person (beneficiary) other than a driver. For example, when the driver is an elderly person, a grandchild of the driver is the beneficiary. That is, when the details of driving of the driver are good, a bonus is given to the grandchild of the driver. By providing such a bonus service, the driver is motivated to improve the quality of the driving operation. In Japanese Unexamined Patent Application Publication No. 2015-210547 (JP 2015-210547 A), when watching the action of a watching target person such as an elderly person, a camera is used to capture an image of the watching target person. The image of the watching target person is replaced with an avatar image. Thus, the privacy of the watching target person is protected. SUMMARY A driving diagnosis obtained when the watching target person drives the vehicle may be sent to a watcher as well as the watching target person. When the monitoring target person and the watcher communicate with each other about the sent driving diagnosis, improvement in the driving operation by the watching target person can be expected. However, it may be difficult to immediately check the driving diagnosis, for example, because the watcher is at business. Therefore, the present specification discloses a driving diagnosis system capable of achieving more active communication between a watching target person and a watcher. A driving diagnosis system disclosed herein includes a processor and a storage medium. The storage medium stores a program. The processor is configured to execute the program to implement an acquisition unit, a diagnosis unit, and a message application providing unit. The acquisition unit is configured to acquire driving data of a watching target person from a vehicle. The diagnosis unit is configured to perform driving diagnosis based on the driving data. The message application providing unit is configured to display, on a chat screen, messages input by the watching target person and a watcher. The message application providing unit includes a display control unit and a message generation unit. The display control unit is configured to display messages on the chat screen. The message generation unit is configured to generate a reaction message to a result of the driving diagnosis after a notification message for notification that the result of the driving diagnosis has been generated is displayed on the chat screen. With the above configuration, the reaction message to the result of the driving diagnosis is input to the chat screen on behalf of the watcher. Thus, the communication about the result of the driving diagnosis is made active. In the above configuration, the display control unit may be configured to display the reaction message on the chat screen after a predetermined waiting period for waiting for input of a message by the watcher has elapsed from a point in time when the notification message was displayed on the chat screen. With the above configuration, it is possible to reduce the occurrence of a case where the reaction message generated by the message generation unit is displayed on the chat screen before a reaction message is input by the watcher. In the above configuration, the message generation unit may be configured to determine whether the reaction message is generable based on a frequency of input of the message by the watcher. The message generation unit is provided to assist communication of the watcher. In a case where the communication of the watcher is active, the generation of the reaction message is restricted, thereby suppressing interference with the communication between the watching target person and the watcher. In the above configuration, the message generation unit may be configured to transmit a safety check message after a predetermined observation period has elapsed from a point in time when a latest message was input by the watching target person. In the above configuration, when the motion of the watching target person is unknown from the message application, the safety check message is displayed to prompt the watching target person to make a response. In the above configuration, the result of the driving diagnosis may include an evaluation of a cognitive function of the watching target person. In this case, the observation period may be determine
