A kind of control method for car radio

Abstract

The invention provides a control method for a car radio and belongs to the field of car radios. The control method includes: receiving an automatic station search instruction for indicating to enter a target mode; controlling the car radio to search for a station with a step frequency and recording the first target parameters of each frequency point; judging the target mode contained in the automatic station search instruction Is it the quality priority mode or the quantity priority mode; when the target mode is the quality priority mode, store the frequency point where the first target parameter meets the first preset condition, so as to ensure the quality of the searched station; when the target mode is In the quantity priority mode, the frequency points whose first target parameters satisfy the second preset condition are stored, so as to ensure the number of stations searched. The control method for the car radio of the present invention can meet the personalized requirements of users and effectively improve the noise reduction effect.

Description

technical field [0001] The invention relates to the field of car radios, in particular to a control method for car radios. Background technique [0002] Traditional car radios have the function of automatic channel search. The common solution is as follows: After clicking to execute the automatic channel search function, the radio searches for stations with stepping frequency and checks and judges the effective frequency points at the same time. The frequency points that meet the conditions will be stored In the list; when the signal quality of the radio station deteriorates, the radio starts the internal solidified noise reduction processing mechanism to improve the listening effect. [0003] When the traditional car radio is searching for channels, the software filters the signal of the station by setting a fixed standard value, and performs a fixed mode of noise reduction processing on the demodulated sound signal. When the standard value is set too high, there may be a ...

AI Technical Summary

Problems solved by technology

When the standard value is set too high, there may be a phenomenon that the number of effective locked stations is very small, which cannot meet the needs of users; if the standard value is set too low, the number of effective locked stations can be increased, but the quality of the radio stations may be poor, and the user produce irritability

[0004] Therefore, the existing car radio has the problem of being unable to meet the user's individual requirements when automatically searching for stations.
