摘要

A vehicular system includes a vehicle side unit and mobile devices registered to the vehicle side unit. The vehicle side unit transmits a first request signal designating a first mobile device. A replying section of the first mobile device replies a response signal when receiving the first request signal. A replying section of a second mobile device replies a non-designated report signal when receiving the first request signal at a time point different from a time point at which the first mobile device replies the response signal. The vehicle side unit includes a vehicle side receiving section receiving the signal transmitted from the replying section of each mobile device and a locked-in determiner determining that only the first mobile is locked in the compartment of the vehicle when the response signal from the first mobile device is received and the non-designated report signal is not received.
