Embodiment Construction

[0015] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] Such as figure 1 As shown, the radio receiver for a car includes a plurality of antennas, namely, a main antenna 1 and a sub antenna 2 .

[0017] The comparator 30 compares the strength of a signal selected from the diversity receiving module 10 and input to the audio system with a predetermined reference value, and then inputs the result to the diversity receiving module 10 .

[0018] The diversity receiving module 10 selects a high-intensity signal from the radio signals received by the main antenna 1 and the auxiliary antenna 2, and outputs it to the audio system through an amplifier 20 . The programming of the diversity receiving module 10 makes it possible to select a radio wave signal according to the input result of the comparator 30 (for example, if the input signal strength from the audio system is greater than the reference va...

Abstract

A radio receiver for a vehicle and a control method thereof is disclosed. The radio receiver includes a diversity receiver module which selects a radio signal having small intensity a smaller wave signal to input into an audio system if the intensity of a signal inputted to an audio is higher than a reference value, thereby simplifying a configuration and reducing the produce cost.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Application No. 10-2003-0051954 filed on July 28, 2003, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a diversity system radio receiver for automobiles and its control method. Background technique [0004] Luxury cars often use diversity systems to improve radio reception. [0005] The diversity system is a switching system that divides a group of FM signals received by the glass antenna into a main antenna (FM1) and a secondary antenna (FM2) to compare the value of each radio wave received and output the higher value . Therefore, when the radio wave intensity of the main antenna is low due to geographical location, the diversity system can replace the reception value of the main antenna with the reception value of the secondary antenna. [0006] Automotive radio receivers can also us...
