Onboard system, onboard device, information processing method, and information processing program

An onboard device comprising:

• a remaining amount detector that detects a remaining amount of a power source remaining in a vehicle;
• a lighting detector that detects that a low power source indicator provided in the vehicle lights up;
• a lighting remaining amount storage unit that stores, as a lighting remaining amount, the remaining power source amount detected by said remaining amount detector at a timing at which said lighting detector detects the lighting;
• a notification remaining amount detector that detects a remaining power source amount larger by a predetermined amount than the lighting remaining amount stored in said lighting remaining amount storage unit;
• and
• a notifier that notifies information for promoting supply of the power source after the remaining power source amount larger than the lighting remaining amount by the predetermined amount is detected before the lighting remaining amount is detected.

An information processing method comprising:

• detecting a remaining amount of a power source remaining in a vehicle;
• detecting that a low power source indicator provided in the vehicle lights up;
• storing, as a lighting remaining amount, the detected remaining power source amount at a timing at which the lighting is detected in the detecting that the low power source indicator lights up;
• detecting a remaining power source amount larger by a predetermined amount than the stored lighting remaining amount;
• and
• notifying information for promoting supply of the power source after the remaining power source amount larger than the lighting remaining amount by the predetermined amount is detected before the lighting remaining amount is detected.

A non-transitory computer readable medium storing a program for causing a computer to execute a method, comprising:

• detecting a remaining amount of a power source remaining in a vehicle;
• detecting that a low power source indicator provided in the vehicle lights up;
• storing, as a lighting remaining amount, the detected remaining power source amount at a timing at which the lighting is detected in the detecting that the low power source indicator lights up;
• detecting a remaining power source amount larger by a predetermined amount than the stored lighting remaining amount;
• and
• notifying information for promoting supply of the power source after the remaining power source amount larger than the lighting remaining amount by the predetermined amount is detected before the lighting remaining amount is detected.
