Abstract
A vehicle system comprises an onboard apparatus that is mounted to a vehicle, and a portable device. The vehicle system controls the vehicle according to a result of collation using wireless communication in which a signal is transmitted and received on electric wave, between the onboard apparatus and the portable device. The onboard apparatus includes a vehicle-side transmission processor that transmits a first signal which specifies signal intensity information and, following transmission of the first signal, transmits a second signal having a signal intensity, the signal intensity information being information on the signal intensity of the second signal. The portable device includes a portable device-side reception antenna that receives a signal transmitted from the vehicle-side transmission antenna, a signal intensity measurement portion, and a reply determiner that determines whether a replay is performed to the onboard apparatus for the collation.
