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, refer to figure 1 and figure 2 A wireless broadcast receiving device for a vehicle according to an embodiment of the present invention will be described.

[0014] The navigation system 10 for vehicles includes a plurality of functions of one example of a controller of a wireless broadcast receiving device. Such as figure 1 As shown, a 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 means 2 obtains map data and various data from an external storage device storing 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 the traffic ...

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 invention relates to a wireless broadcast receiving device for vehicles. Background technique [0002] JP 2003-152575A discloses an apparatus which includes a plurality of frequency division multiple receivers and tunes the corresponding receivers to channels of different broadcast service areas. Such a device is therefore capable of receiving traffic information for multiple areas. [0003] A receiving mechanism is configured only for receiving traffic information from a traffic information broadcasting station in a wireless manner (hereinafter, this receiver is called a traffic information receiver); another receiving mechanism is configured for wirelessly and selectively Traffic information and broadcast programs are received from a radio broadcasting station (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); thus, this...
