Abstract: A system includes: a transmission device provided on a vehicle, for transmitting a signal including a vehicle ID within an area set in advance; a receiving means for receiving the signal; an external control means provided on the vehicle, for receiving a command including an authentication key for a usage right, and for performing vehicle state control including at least unlocking/locking a door of the vehicle from outside a control system inherent in the vehicle; a communication connection means for establishing a communication link to send the command from a user terminal to the external control means; and a management server located on a communication network, for linking and managing the vehicle ID with a status of the usage right.

Abstract: An onboard system that reduces a mental pressure on a driver includes 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 the remaining amount detector at a timing at which the lighting detector detects the lighting of the low power source indicator, a notification remaining amount detector that detects a remaining power source amount larger by a predetermined amount than the lighting remaining amount stored in the 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.
