Abstract

The invention discloses a vehicular radio control method and device, a vehicular radio and a vehicle; wherein the device comprises a monitoring module for creating a monitoring thread so as to monitor RSSI (Received Signa Strength Indication) information and SNR (SIGNAL-NOISERATIO) information of a current geographic position; an analyzing and smoothing module for analyzing and smoothing the RSSI information and the SNR information, thus obtaining smooth RSSI parameters and smooth SNR parameters; a radio quality parameter determining module for determining the integral radio quality parameter of the vehicular radio according to the RSSI information and the SNR information; and a processing executing module for judging whether the integral radio quality parameter is more than a set threshold value and reducing the playing volume of the vehicular radio if the integral radio quality parameter is more than the set threshold value. According to the method, the device, the vehicular radio and the vehicle provided by the invention, the integral radio quality is judged according to the RSSI and the SNR, and therefore, the playing volume of the radio is adjusted according to the set threshold value, thus reducing noises.

Description

technical field [0001] The invention relates to the field of radios, in particular to a control method and device for a vehicle-mounted radio in the field of vehicles, a vehicle-mounted radio and a vehicle. Background technique [0002] FM / AM radio is a relatively frequently used device, and it is more and more applied to products such as automobiles and mobile phones. However, a vehicle is a moving object that may enter garages, undergrounds, culverts or suburban areas, but in garages, undergrounds, culverts, etc. Or in the suburbs, it may be impossible to receive FM / AM signals. At this time, the radio will produce extremely loud noises, which will damage people's hearing, affect the user's emotions and experience, and require the user to manually adjust the volume or change the channel. Solve the noise problem. [0003] Therefore, in view of the above-mentioned problems in the prior art, it is necessary to study a control device or method for a car radio to solve the tech...
