Example (b):
referring to fig. 1, a schematic view of an application scenario of a car-mounted device volume compensation method according to an embodiment of the present invention is shown, where the car-mounted device volume compensation method is applied to a car-mounted system with an audio management function. As shown in fig. 1, the in-vehicle system 100 includes an audio management system 110. Further, as shown in fig. 2, the audio management system includes a connection module 111, a control module 112, and an audio output module 113.
The connection module 111 is used for managing audio input sources, such as playing music or making a call through a bluetooth headset, playing usb sound sources, playing local sound sources, and the like. Specifically, the connection module 111 is used to connect the local disk and the bluetooth mobile phone to perform audio input, such as multimedia music input source, system sound, or input of the bluetooth mobile phone. The control module 112 is configured to set an audio control policy, that is, to control which sound source can be output, detect related information, and execute a volume policy of the currently played sound source according to the related information; the related information is mainly information for determining volume compensation. The audio output module 113 is mainly an output device for controlling the current audio, and is usually referred to as a vehicle speaker for output. The sound output by the vehicle speakers generally includes: navigation, answering/making calls, radio, playing music, news voice broadcast, VR voice recognition, vehicle warning tones, system alert tones, and the like. The car machine volume compensation method mainly compensates for the output sound types.
Referring to fig. 3, a car-mounted device volume compensation method is shown, wherein the volume compensation method includes:
s110: the current speed of the vehicle is obtained.
In some possible embodiments, as shown in fig. 4, the step S110 may include the following steps:
s111: judging whether the speed of the vehicle changes or not;
s112: and if the speed of the vehicle changes, acquiring the current speed of the vehicle.
Further, the current vehicle speed can be detected through a control module of the audio management system, and if the vehicle speed changes, an external Electronic Control Unit (ECU) sends the current vehicle speed to the control module through network Remote Procedure Call (RPC) communication. The vehicle speed range detected by the control module can be 0-200 KM/h.
S120: and acquiring the current playing volume of the vehicle audio.
In some possible embodiments, as shown in fig. 5, the step S120 may include:
s121: acquiring the output voltage of the playing equipment when the vehicle audio is played;
s122: and calculating the current playing volume according to the rated voltage of the playing equipment and the output voltage.
In an embodiment of the present invention, the volume may be expressed in a logarithmic manner following Weber's law and fisher's law (Weber-Fechnerlaw). In the Android system, the volume may also be called loudness and intensity, which refers to the subjective feeling of the human ear on the magnitude of the heard sound, and the objective evaluation scale is the amplitude of the sound. This sensation is derived from the pressure, i.e. sound pressure, generated when the object vibrates. The object vibrates through different media, conducting its vibrational energy away. In order to quantify the perception of sound as a monitorable indicator, one divides the sound pressure into "levels" -sound pressure levels, so that the intensity of the sound can be objectively represented in units called "decibels" (dB).
Wherein dB is defined as 20lg (Volume), wherein Volume is Volume, and can be understood as the ratio of the voltage output by the loudspeaker to the rated voltage (representing the range between 0 and 1); namely Volume ═ exp ((dB × ln 10)/20). Specifically, the voltage varies with the change in decibels, and the relationship between the two conforms to a logarithmic curve, which is a volume curve, and the volume curve described below has a dB range of (-99 to 0dB) and an output voltage range of (0v to 5 v).
S130: and acquiring the current compensation level of the vehicle, and determining a corresponding volume compensation table according to the current compensation level, wherein the volume compensation table stores the corresponding relation among the vehicle speed parameter, the playing volume parameter and the volume compensation information.
It will be appreciated that the compensation for volume may be set to a number of levels, each level having its corresponding compensation policy, based on user-defined settings or product provider presets.
For example, in some possible embodiments, the compensation levels may include a High level (High), a medium level (Mid), and a Low level (Low), in which case the compensation amount of the High level is greater than that of the medium level. Therefore, the user can select the corresponding compensation grade to compensate according to the requirement of the user, and better use experience is obtained. Of course, according to the actual situation, only the high level, the medium level and the low level can be set, and other self-defined levels can be set to meet the actual requirements. In the embodiment of the present invention, only the high, medium and low compensation levels are described. In addition, in actual operation, a certain grade may be selected as a default grade, for example, a middle grade may be selected as a default grade, or a grade frequently used by a user may be automatically selected as a default grade.
In some possible embodiments, the volume compensation information may be an offset of the audio volume, that is, the volume that needs to be increased or decreased based on the current volume.
Specifically, as shown in tables 1 to 3, there are a compensated volume table at a low level of compensation, a compensated volume table at a medium level of compensation, and a compensated volume table at a high level of compensation, respectively. In the table, the longitudinal direction represents the vehicle speed parameter (taking the detection range of 0-200 KM/h as an example), the transverse direction represents the dB value of the playing volume parameter, and the content in the table unit represents the offset of the audio dB value increased according to the playing volume parameter and the vehicle speed parameter. In addition, the compensation volume table may be a data structure imported at initialization of the audio management system.
TABLE 1
TABLE 2
TABLE 3
S140: and processing the current vehicle speed and the current playing volume according to the volume compensation table, and acquiring the corresponding volume compensation information from the volume compensation table according to the processing result.
In some possible embodiments, the processing of the current vehicle speed and the current playing volume may be quantization processing; the quantization processing can be understood as that the current vehicle speed is judged to be in an interval range corresponding to a certain two vehicle speed parameters, the difference value between the current vehicle speed and two end points of the interval is compared, and the end point value with the smaller difference value is selected as the vehicle speed parameter for selecting the volume compensation information from the volume compensation table. Similarly, judging that the current playing volume is in an interval range corresponding to a certain two playing volume parameters according to the current playing volume, comparing the absolute value of the difference value between the current playing volume and two endpoints of the interval, and selecting the endpoint value with smaller absolute value of the difference value as the playing volume parameter for selecting volume compensation information from a volume compensation table.
Taking the above table as an example, for example, if the current compensation level of the vehicle is obtained as the middle level, the corresponding volume compensation table is determined as the compensation table of the middle level compensation level, that is, table 2. And if the obtained current vehicle speed is 87km/h and the current playing volume is-48 dB, respectively carrying out quantization processing on the current vehicle speed and the current playing volume. The current vehicle speed is quantized to judge that the current vehicle speed is 87km/h in a vehicle speed parameter 80 km/h-vehicle speed parameter 90km/h interval, the absolute value of the difference between the current vehicle speed 87km/h and the vehicle speed parameter 80km/h is 7, the absolute value of the difference between the current vehicle speed 87km/h and the vehicle speed parameter 90km/h is 3, and then 90km/h is selected as an actual vehicle speed parameter; the quantization processing of the current playing volume can be that-48 dB of the current playing volume is judged to be in the interval of-45 dB of the playing volume parameter and-50 dB of the playing volume parameter, the absolute value of the difference value between the current playing volume-48 dB and the playing volume parameter-45 dB is 3, the absolute value of the difference value between the current vehicle speed-48 dB and the playing volume parameter-50 dB is 2, and then-50 dB is selected as the actual playing volume parameter. Therefore, in the compensation table of the middle-level compensation level, the vehicle speed parameter is 90km/h, the playing volume parameter is-50 dB, and the 15dB offset is obtained as volume compensation information.
Further, if the current vehicle speed or the current playing volume is a median, a larger parameter is taken as a vehicle speed parameter or a playing volume parameter. For example, if the current vehicle speed is 85km/h, the current playing volume is-47.5 dB, which is the median of the vehicle speed parameter and the playing volume parameter, respectively, i.e., the absolute value of the difference between the current vehicle speed 85km/h and the vehicle speed parameter 80km/h is equal to the absolute value of the difference between the current vehicle speed 90km/h and the absolute value of the difference between the current playing volume-47.5 dB and the playing volume parameter-45 dB is equal to the absolute value of the difference between the current playing volume-50 dB and the playing volume parameter-45 dB. Then, 90km/h is selected as an actual vehicle speed parameter, 45dB is selected as an actual playing volume parameter, and 12dB offset is obtained according to the actual playing volume parameter to serve as volume compensation information.
The corresponding volume compensation information can be dynamically searched from the corresponding volume compensation table through the current vehicle speed and the current playing volume acquired in real time, so that the volume compensation can be compensated along with the actual working condition.
S150: and compensating the current playing volume of the vehicle audio according to the volume compensation information to obtain the actual playing volume.
S160: and playing the vehicle audio according to the actual playing volume.
In some possible embodiments, as shown in fig. 6, the step S160 further includes:
s161: acquiring the category of the vehicle audio;
s162: and outputting the vehicle audio to corresponding playing equipment for playing according to the category of the vehicle audio.
It will be appreciated that there are many audio categories in the car system, such as navigation, answering/making calls, radio, playing music, news voice broadcasts, VR voice recognition, vehicle warning tones, system alert tones, etc. The way it is played is different for different classes of audio.
In some possible embodiments, the audio may be output to the corresponding playback device through Policy. Specifically, the Policy policies mainly include Policy1 Policy and Policy2 Policy. Wherein, Policy1 is to output audio such as multimedia music/radio to the front and back rows of the automobile; policy2 means that in addition to other audio in Policy1 (e.g., multimedia music, radio, etc.) as described above, such as navigation, telephone, alarm, etc., audio can be output at the front row of the car. And an output module of the audio management system judges and implements an output Policy strategy of the audio management system according to the type of the currently played sound, so that the corresponding sound is output at a proper position.
Through the mode, the volume of multimedia output by the vehicle can be changed along with the change of the vehicle speed, and when the engine stops running, the strategy for volume compensation is invalid. The problem of in the driving process, because tire noise, engine noise and wind noise etc. cause experience effect poor to audio output can be solved.
The actual driving road conditions of the vehicle are complex, for example, the external noise may be different when the vehicle is driven on a highway, an urban area, a rural area, a rainy or snowy day, a windy day, a clear sky, etc. Specifically, for the road conditions, the road conditions on a common expressway are better, and the wind noise and the tire noise are consistent with the situations; the noise of the urban road also takes the noise of the environment into consideration besides the tire noise and the wind noise; the rural roads have the condition of uneven gravel road and the like, and the tire noise can be increased. For the weather, the wind noise is smaller in clear sky and breeze; wind noise increases in windy days; and the tire noise is reduced in rainy and snowy days. Among them, the snow tire noise is reduced because a water film is formed between the tire and the road surface to separate friction between the tire and the road surface, so that the noise is reduced. The same factor exists in snowy weather, snow and tire friction is reduced, and tire noise is naturally reduced. Therefore, the following solutions are provided in the embodiments of the present invention for different road conditions and weather.
In some possible embodiments, as shown in fig. 7, the influence of the road condition on the volume compensation is mainly considered, and the volume compensation method may further include:
s210: acquiring current road condition information of the vehicle;
s220: determining road condition compensation information according to the current road condition information and the current compensation grade;
s230: and compensating the current playing volume according to the road condition compensation information and the volume compensation information to obtain the actual playing volume.
Before step S210, the implementation steps of steps S110 to S140 may be further included, and step S150 may be implemented by step S230.
It is understood that the road condition compensation information may be different for different road condition information and different current compensation levels. Specifically, the traffic compensation information may be a specific volume compensation value. For example, if the current volume compensation level is medium and the road condition of the vehicle is a highway, the road condition compensation value is 0, that is, the volume compensation gain is compensated according to the above table 2. If the road condition of the vehicle is urban road, the road condition compensation value is set to be 3dB, namely 3dB is added on the basis of the volume compensation value in the table 2. If the road condition of the vehicle is a country road and the vehicle speed is lower than 60KM/h, the road condition compensation value is set to 2dB, that is, 2dB is added on the basis of the volume compensation value in table 2.
In other possible embodiments, as shown in fig. 8, mainly considering the influence of weather on the volume compensation, the volume compensation method may further include:
s310: acquiring current environmental information around the vehicle;
s320: determining environmental compensation information according to the current environmental information;
s330: and compensating the current playing volume according to the environment compensation information and the volume compensation information to obtain the actual playing volume.
Before step S310, the implementation steps of steps S110 to S140 may be further included, and step S150 may be implemented by step S330.
It will be appreciated that the environmental compensation information may also be different for different environmental information, mainly the weather conditions around the vehicle while it is running, and different current compensation levels. Specifically, the traffic compensation information may be a specific volume compensation value. For example, if the current volume compensation level is medium and the environment around the vehicle is breeze in a sunny day, the environment compensation value is 0, that is, the volume compensation gain is compensated as shown in table 2. If the environment around the vehicle is windy, the environment compensation value is set to be 3dB, namely 3dB is added on the basis of the volume compensation value in the table 2. Wherein, the grade of blowing can be regarded as the strong wind weather at 5 ~ 7 grades. If the environment around the vehicle is rainy or snowy weather, setting the environmental compensation value to be 2dB, namely reducing the environmental compensation value by 2dB on the basis of the volume compensation value in the table 2; but the actual volume value after the reduction is larger than the volume value before the uncompensation, that is, the volume value when the volume compensation function is turned off.
