Vehicle receiver system, vehicle receiver, and operating method for vehicle receiver
First Claim
1. A vehicle receiver system comprising:
- a receiver that is provided in a vehicle cabin, wherein an operating mode of the receiver includes a first mode in which processing is performed to receive a first wireless signal for key verification, transmitted from a portable key, and a second mode in which processing is performed to receive 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 a key verification on the portable key in the vehicle cabin on the basis of the first wireless signal received by the receiver, wherein;
in a predetermined situation where the key verification device performs the key verification continuously, the receiver is configured such that the operating mode of the receiver is alternated between the first mode and the second mode; and
in the predetermined situation, a 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.

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.

9. A vehicle receiver provided in a vehicle cabin comprising:
-
a receiving unit having a plurality of operating modes including a first mode in which processing is performed to receive a first wireless signal for key verification, transmitted from a portable key, and a second mode in which processing is performed to receive a second wireless signal relating to a tire air pressure, transmitted from a transmitter provided on a tire; and a switching control unit that alternates the operating mode of the receiving unit between the first mode and the second mode in a predetermined situation where key verification on the basis of the first wireless signal is performed continuously, wherein in the predetermined situation, a proportion of a second mode operation time in which the receiving unit 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.

10. An operating method for a vehicle receiver provided in a vehicle cabin comprising:
-
when the receiver is operated in a first mode, performing processing to receive a first wireless signal for key verification, transmitted from a portable key; when the receiver is operated in a second mode, performing processing to receive a second wireless signal relating to a tire air pressure, transmitted from a transmitter provided on a tire; and in a predetermined situation where key verification on the basis of the first wireless signal is performed continuously, alternating an operating mode of the receiver between the first mode and the second mode, wherein in the predetermined situation, a 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.
