Problems solved by technology

However, if the radio receiver has already been tuned to the broadcast program by the user, and then simply suddenly tunes to the traffic information of this adjacent area when approaching the boundary, the user cannot continue to listen to this broadcast program
Doing so would reduce the value or user friendliness of the radio receiver as a radio tuner

Embodiment Construction

[0013] Below, reference figure 1 with figure 2 A wireless broadcast receiving device for a vehicle according to the embodiment of the present invention will be described.

[0014] The navigation system 10 for a vehicle includes multiple functions of an example of a controller of a wireless broadcast receiving device. Such as figure 1 As shown, the navigation system 10 includes a position detector 1, a map data obtaining device 2, and a plurality of operation switches 3. The position detector 1 detects the current position of the vehicle. The map data obtaining device 2 obtains map data and various data from an external storage device that stores map data and various data. The operation switch 3 is used to allow the user to input instructions.

[0015] The navigation system 10 also includes a traffic information receiver 4, a radio receiver 5, a display device 6 and a controller 7. The traffic information receiver 4 is a radio tuner that can only be tuned to a traffic informatio...

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.

Description

Technical field [0001] The present invention relates to a wireless broadcast receiving device for vehicles. Background technique [0002] JP 2003-152575A discloses a device that includes a plurality of frequency division multiple receivers and tunes the corresponding receivers to channels in different broadcasting service areas. Therefore, this device can receive traffic information in multiple areas. [0003] One receiving mechanism is made to be used only to receive traffic information from traffic information broadcasting stations in a wireless manner (this receiver is called traffic information receiver hereinafter); another receiving mechanism is made to be used in a wireless manner and selectively Receive traffic information and broadcast programs from radio stations (hereinafter, this receiver is called a radio receiver). There may be some traffic information broadcasting stations located in multiple regions (such as counties or countries); therefore, this traffic informat...
