Abstraction
This chapter provides requirements for the function of message notification function.
In products, message notification functions are required in various situations. For example, when an anomaly occurs in a system, there may be a case where the anomaly is messaged. The requirements for the function to notify messages for such cases are described.
Use cases
In the following table, use cases which need the message notification for services are described.
# | Item | User |
1 | The user searches for a destination and uses the navigation system to display the route. The user sets the destination in the navigation system and follows the navigation system's guidance to drive to the destination. In this case, if the function to display a map is not working properly due to the lack of the remaining memory, the destination cannot be displayed properly or the screen will stop. When there is not enough memory left, an event will be issued to notify the necessary applications in the system. Then, in order to display the map correctly, the entire system will be automatically restarted and the user can use the navigation system normally, but before that, the necessary applications can take fail-safe actions. | Driver |
