Wireless broadcast receiving device for vehicle
First Claim
1. A wireless broadcast receiving device for a vehicle, comprising:
- a first receiver that wirelessly receives traffic information from one of a plurality of traffic information broadcasting stations;
a second receiver that wirelessly and selectively receives one of (i) traffic information from one of the traffic information broadcasting stations and (ii) a radio program from a radio broadcasting station;
a storage device that stores correspondence data that associates each of the traffic information broadcasting stations with a certain region included in a plurality of regions, wherein traffic information from the each of the traffic information broadcasting stations is receivable in the certain region;
a position detector that detects a current position of the vehicle; and
a controller that includes a tuning unit that tunes the first receiver and the second receiver to the traffic information broadcasting stations based on the detected current position and a determining unit that makes a determination whether or not the second receiver is in use when the vehicle approaches a border between (i) a current region including the current position and (ii) a neighboring region adjacent to the current region, while the first receiver is tuned to a first station of the traffic information broadcasting stations which is associated with the current region, wherein the tuning unit tunes one of the first receiver and the second receiver to a second station of the traffic information broadcasting stations which is associated with the neighboring region, based on the determination made by the determining unit.

Abstract
A vehicle is provided with a navigation system that includes a traffic information receiver and a radio receiver. The traffic information receiver receives traffic information from one of multiple traffic information broadcasting stations having respective service regions. The radio receiver selectively receives (i) traffic information from one of the multiple traffic information broadcasting stations and (ii) a radio program from a radio broadcasting station. When the vehicle approaches a border between (i) a current service region where the traffic information receiver is receiving traffic information and (ii) a neighboring service region, whether the radio receiver is in use or not is determined. Based on the determination, the traffic information receiver or the radio receiver is tuned to a traffic information broadcasting station covering the neighboring service region.

8. A wireless broadcast receiving device for a vehicle, comprising:
-
a first receiver that wirelessly receives traffic information from one of a plurality of traffic information broadcasting stations;
a second receiver that wirelessly and selectively receives one of (i) traffic information from one of the traffic information broadcasting stations and (ii) a radio program from a radio broadcasting station;
a storage device that stores correspondence data that associates each of the traffic information broadcasting stations with a certain region included in a plurality of regions, wherein traffic information broadcasted from the each of the traffic information broadcasting stations is receivable in the certain region;
a position detector that detects a current position of the vehicle; and
a controller that includes a tuning unit that tunes the first receiver to a first station of the traffic information broadcasting stations which is associated with a current region including the current position, and tunes the second receiver to a second station of the traffic information broadcasting stations which is associated with a neighboring region adjacent to the current region when the second receiver is not in use when the vehicle approaches a border between (i) the current region and (ii) the neighboring region; and
a determining unit that makes a determination whether a broadcasting station, to which the second receiver is tuned, accords with the first station when the second receiver is in use when the vehicle approaches the border, wherein when the broadcasting station to which the second receiver is tuned is determined to be according with the first station, the tuning unit switches a traffic information broadcasting station, to which the first receiver is tuned, from the first station to the second station. - View Dependent Claims (9)
