Abstract
A vehicle receiver system includes: a receiver provided in a vehicle cabin, wherein an operating mode of the receiver includes a first mode for receiving a first wireless signal transmitted from a portable key, and a second mode for receiving a second wireless signal relating to a tire air pressure, transmitted from a transmitter provided on a tire; and a key verification device that performs key verification on the portable key in the vehicle cabin on the basis of the first wireless signal. In a predetermined situation, the receiver is configured such that the operating mode of the receiver is switched between the first mode and the second mode, and proportion of a second mode operation time in which the receiver operates in the second mode is set to be greater when a vehicle speed is relatively high than when the vehicle speed is relatively low.
