Problems solved by technology

[0003] In the existing car audio playback devices, it is generally not combined with the driving situation and the impact of audio on the driver's psychological emotions to optimize the control of audio playback
Therefore, the Chinese patent with the publication number CN 104750685 A mentions a method of using the corresponding relationship between scenes and music to recommend different music in different scenes, but this method cannot automatically classify music according to various complex scenes. Manually establish the classification relationship; the Chinese patent with the publication number CN 104978983A also mentions the application scenario of optimizing the audio playback content according to the external environment, but this patent performs music classification and recommendation according to the label information in the music file. For most music files In general, there is no perfect label to mark the music style, so it is also necessary to manually set the music label, and if the music label is set incorrectly, it will have the opposite effect
For example, if you are in an extremely congested road situation, if you play rock music with a strong rhythm, it is likely to increase the restlessness of the car owner and increase the probability of a scratch accident; in a high-speed road with good road conditions and stable speed, If soothing music is played for a long time, it may induce the car owner to enter a drowsy state, reduce the reaction speed of the car owner, and increase the probability of high-speed accident risk

Embodiment 1

[0078] A method for random playing of vehicle audio, comprising:

[0079] S101: Obtain the rhythm of all playable songs; sort all playable songs according to the rhythm of the songs from low to high;

[0080] S102: Use GPS to obtain the current position of the vehicle; upload the position to the real-time road condition server through wireless networks such as 2G / 3G / 4G, and query to obtain the congestion index; calculate the speed of the vehicle within the time period from the current moment to the previous 5 minutes mean and variance;

[0081] S103: If the above average value is less than 15 kilometers per hour, the variance is greater than 50, and the traffic index is greater than 8, it is determined that the current driving state is the first state, that is, the congestion state; if the above average value is greater than 60 kilometers per hour, the variance is less than 10 And the traffic index is less than 2, then it is determined that the current driving state is the se...

Embodiment 2

[0088] A method for random playing of vehicle audio, comprising:

[0089] S201: Obtain the rhythm of all playable songs; sort all playable songs according to the rhythm of the songs from low to high;

[0090] S202: create a sequence 1; obtain the total number of all playable songs; sequentially select an element combination whose group number is the same as the total number of all playable songs in sequence 1, and the number of elements in the element combination is sequentially increased, and Each element does not repeat each other; according to the arrangement order of the songs and the order of the element combinations, the songs and the element combinations are associated one by one;

[0091] S203: create a sequence 2; obtain the total number of all playable songs; sequentially select an element combination whose group number is the same as the total number of all playable songs in sequence 2, and the number of elements in the element combination is in descending order, an...

Embodiment 3

[0100] A method for random playback of vehicle audio, the difference from the first embodiment above is:

[0101] The above-mentioned S104 is specifically:

[0102] S1041: Obtain the number N and arrangement order of audio data;

[0103] S1042: If the current driving state is the first state, then create a sequence 1, which contains N(N+1) / 2 elements, and associate each song with K consecutive elements in the sequence 1; Said N is the total number of songs that can be played, and K is the sequence number of each song; if the songs are sorted as 1-10, sequence 1 includes elements a1-a55, and song 1 is associated with a1, and song 2 is associated with a2 and a3 ;

[0104] If the current driving state is the second state, then create sequence 2, which contains N(N+1) / 2 elements, and associates it with N-K+1 elements in sequence 2 for each song;

[0105] If the current driving state is a state other than the first state and the second state, a sequence 3 is created, which conta...

Abstract

The present invention provides a car audio randomly playing method. The method comprises: acquiring a rhythm of all audio data; sorting all audio data according to the order of the volume level of therhythm of the audio data; acquiring a traffic index of a current location of the vehicle and a current speed parameter of the vehicle; creating a sequence according to the traffic index and the speedparameter; selecting a different number of elements from the sequence according to an arrangement order of the audio data, and associating the audio data with the different number of elements obtained by selection, wherein the elements corresponding to each piece of audio data are not repeated; randomly selecting the elements in the sequence; and playing the audio data corresponding to the selected elements. According to the method provided by the present invention, a play probability conforming to the current driving state is set for each piece of audio data, so that the music with the appropriate rhythm is played according to the current road condition and the vehicle state, and the adverse effect of the audio entertainment system on the driver is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle multimedia, in particular to a method for randomly playing vehicle audio. Background technique [0002] The car audio entertainment system can play audio files including MP3, WMA, CD, etc. Although the audio entertainment system is a common configuration in modern cars, the entertainment function and the driving safety of the car owner have always been a problem that requires mutual balance and optimization. The stronger the impact of entertainment functions on the car owner's attention or emotions, the more likely dangerous traffic accidents will occur. In fact, the music played by the car audio entertainment system has a direct impact on the mood of the car owner. The relationship between music and human emotions is a branch of music psychology. In the field of international psychology, there is an academic journal dedicated to the relationship between human emotions and music. Psychology of Mu...
