Information notification method, information notification system, and recording medium for user who parks vehicle

An information notification system comprising:

• a navigation system mounted in a vehicle, the navigation system guiding a user to a destination and a parking lot;
• and
• a mobile device carried by the user and capable of communicating with the navigation system,
• wherein the mobile device includes a processor and a non-transitory recording medium having a computer program therein, and the computer program causes the processor to perform,
• obtaining a parking time limit during which the user is allowed to continuously park the vehicle at the parking lot,
• measuring a travel time required for the user to move from the parking lot to the destination,
• obtaining a round trip time required for the user to make a round trip between the destination and the parking lot,
• calculating a remaining time during which the user is allowed to stay at the destination by subtracting, from the parking time limit, the round trip time and an elapsed time measured from when the user has reached the destination,
• determining whether the remaining time is less than or equal to a threshold value preset to a value that is greater than or equal to zero, and
• notifying the user that the remaining time is short if it is determined that the remaining time is less than or equal to the threshold value.

A non-transitory computer-readable recording medium storing a computer program for use in an information notification system including a navigation system mounted in a vehicle and a mobile device of a user, the navigation system guiding the user to a destination and a parking lot, the mobile device being capable of communicating with the navigation system, the computer program causes a processor of the mobile device to perform:

• obtaining a parking time limit during which the user is allowed to continuously park the vehicle at the parking lot;
• measuring a travel time required for the user to move from the parking lot to the destination;
• obtaining a round trip time required for the user to make a round trip between the destination and the parking lot;
• calculating a remaining time during which the user is allowed to stay at the destination by subtracting, from the parking time limit, the round trip time and an elapsed time measured from when the user has reached the destination;
• determining whether the remaining time is less than or equal to a threshold value preset to a value that is greater than or equal to zero;
• and
• notifying the user that the remaining time is short if it is determined that the remaining time is less than or equal to the threshold value.
