Abstract

The invention discloses a vehicle-mounted radio and a control method. The vehicle-mounted radio comprises a signal receiving module, a frequency discrimination processing module, a micro controller module, a power amplification and volume control module, a positioning module, a human-machine interaction interface, and a loudspeaker; the signal receiving module, the frequency discrimination processing module, the power amplification and volume control module, the positioning module and the human-machine interaction interface are respectively connected with the micro controller module; the loudspeaker is connected with the power amplification and volume control module; the radio further comprises a storage connected with the micro controller module, a radio station database is stored in thestorage; and the radio station database comprises broadcast frequency codes, coordinate codes and station captions and literal data of frequency of the frequency-modulation radio stations at differentregions. Stored radio stations of the radio are automatically updated when the vehicle-mounted radio is switched to the radio function or detecting that the vehicle-mounted radio is across time zones, and the station caption can be displayed by using different colors according to the signal intensity.

Description

technical field [0001] The invention belongs to the technical field of vehicle navigation and entertainment systems, and in particular relates to a vehicle radio and a control method. Background technique [0002] At present, the car's navigation and entertainment system is controlled by a computer chip and has a radio function. The radio is also one of the necessary devices for entertainment while driving. The difference between the car radio and other radios is that the car radio is mobile, which means that the channels that are usually familiar and favorite may become content that you don’t like to listen to when you are in a different place. In addition, during the driving process, the signal strength received by the car radio will keep changing, and when the signal is weak, there will be a "click" noise from the speaker. In addition, picking a station while driving a car is a potential safety hazard. [0003] Therefore, it is necessary to develop a car radio and a co...
