Referring to fig. 5, S30 includes:
s31, obtaining a volume adjustment result according to the state of the passenger;
and S33, controlling the volume in each sound zone according to the volume adjusting result.
So, can realize according to passenger's state, finely tune the volume of each sound zone, the demand of the car condition of fitting more multi-passenger.
Specifically, the volume adjustment result may include a plurality of shift positions, each shift position includes an adjustment direction and an adjustment value, and the passenger state corresponds to the shift position. The volume adjustment results include more adjustment, less adjustment, no change, less adjustment and more adjustment. Specifically, the higher gear may be to adjust the volume to 130%, 140%, 150%, 160%, etc. of the original volume, and the lower gear may be to adjust the volume to 110%, 120%, 130%, etc. of the original volume, and the amplitude of the lower gear adjustment is lower than that of the higher gear adjustment. The more-lowered gear positions can adjust the volume to 30%, 40%, 50% and the like of the original volume, the less-lowered gear positions can adjust the volume to 60%, 70%, 80% and the like of the original volume, and the adjustment range of the less-lowered gear positions is lower than that of the less-lowered gear positions. The more lowered gears can correspond to the state of the passenger for making a call, the less lowered gears can correspond to the state of the passenger for chatting, and the corresponding relation between the gears and the state of the passenger is more, so that specific limitation is not required.
The gear of the volume adjustment result can be 3 gears, 4 gears, 5 gears, 6 gears and the like, and the specific gear of the volume adjustment result can be adjusted according to factors such as user use habits and model construction, and is not limited specifically here. The specific value of each gear adjustment can be set by a manufacturer during production, can also be set by a user according to the use habit of the user, and can also be adjusted by after-sales personnel, without specific limitation.
Further, referring to fig. 6, the passenger statuses include at least four zone passenger statuses, and the at least four zone passenger statuses correspond to the at least four zones one to one, S33, including:
s331, obtaining a state adjusting result corresponding to the sound zone according to the passenger state of the sound zone;
s333, obtaining the sound zone adjusting result of each sound zone according to the state adjusting result and the position relation of at least four sound zones, wherein the volume adjusting result comprises the sound zone adjusting result of each sound zone.
Therefore, the sound zone adjusting results of the sound zones can be obtained, and a basis is provided for finely controlling the volume in each sound zone according to the sound zone adjusting results of the sound zones.
In particular, the voice zone passenger status is used to indicate the status of the passengers within the voice zone. The vehicle 1000 includes four ranges, which are respectively named as a main driving range, an auxiliary driving range, a rear row left range and a rear row right range, and the passenger states include four ranges passenger states respectively corresponding to the passenger states of the four ranges. Specifically, the state adjustment result obtained according to the zone passenger state corresponding to the main driving zone corresponds to the main driving zone, for example, the state adjustment result obtained according to the zone passenger state corresponding to the main driving zone is that the volume is increased by 50%, which means that the volume of the main driving zone needs to be increased by 50%. The sound vice driving area, the rear row left side sound area, the rear row right side sound area and the sound area have the same principle, and detailed description is omitted here.
Between S331 and S333, the status adjustment results may be screened to obtain the status adjustment result that needs to be adjusted. For example, if the state adjustment result obtained is unchanged according to the state of the zone occupant of a zone, the step of obtaining the adjustment result for each zone according to the state adjustment result for that zone and the positional relationship between at least four zones can be omitted. Thus, the calculation steps can be reduced, and the vehicle 1000 can respond quickly; for another example, if the obtained state adjustment result is 50% lower according to the zone passenger state of a zone, S333 is continued to obtain the zone adjustment results of the respective zones.
Further, referring to fig. 7, S333 includes:
s3331, acquiring corresponding weights according to the distances between the at least four sound zones and the sound zones corresponding to the state adjustment result, wherein the larger the distance is, the smaller the weight is;
s3333, obtaining the sound zone adjusting result of each sound zone according to the state adjusting result and the weight.
Therefore, the weights can be obtained by the distances between the at least four sound zones and the sound zones corresponding to the state adjusting results, so that the sound zone adjusting results of all the sound zones can be obtained according to the weights and the state adjusting results, and a basis is provided for finely controlling the volume in all the sound zones according to the sound zone adjusting results of all the sound zones.
Specifically, the closer the two ranges are, the greater the influence therebetween is, and the farther the two ranges are, the smaller the influence therebetween is, and thus the weight decreases with increasing distance. The specific relationship between the weight and the distance can be calculated by setting a formula, or can be set according to experience, vehicle type and the like, as long as the weight is ensured to be gradually reduced along with the gradual increase of the distance. Specifically, the specific relationship between the weight and the distance may be set by a manufacturer, or may be set and adjusted by a user according to a use habit of the user, which is not specifically limited herein.
For ease of understanding, the following examples are given. In one embodiment, the vehicle 1000 includes four zones arranged in a two-by-two rectangular array, and for convenience of description, the four zones are named as a main driving zone, a sub-driving zone, a rear left zone, and a rear right zone according to their positions. Taking the sound zone corresponding to the state adjustment result as the main driving sound zone as an example, and acquiring the weight of the main driving sound zone as 1, the weight of the auxiliary driving sound zone as 0.6, the weight of the rear row left sound zone as 0.6 and the weight of the rear row right sound zone as 0 according to the distances between the four sound zones and the main driving sound zone; and the state adjustment result corresponding to the main driving zone is that the volume is reduced by 50%, the sound is reduced by 50% and weighted according to the weight, and the volume reduction of the main driving zone by 50%, the volume reduction of the auxiliary driving zone by 30%, the volume reduction of the rear left sound zone by 30%, and the volume reduction of the rear right sound zone by 0% are obtained, namely, the volume of the rear right sound zone is unchanged.
It should be noted that, S3331 and S3333 may be performed on the state adjustment result corresponding to each sound zone, and the obtained sound zone adjustment results may be superimposed to obtain a final sound zone adjustment result. The state adjustment results may be first screened to obtain a state adjustment result to be adjusted, only the state adjustment results to be adjusted are subjected to S3331 and S3333, and the obtained range adjustment results are superimposed to obtain a final range adjustment result.
The volume control method in the vehicle 1000 further includes:
the volume level in each zone is controlled according to the passenger status and the current driving speed of the vehicle 1000.
Therefore, the passenger state and the current running speed of the vehicle 1000 can be considered at the same time, and the volume in each sound zone can be controlled to be more suitable for the actual use condition.
It is understood that, in general, the higher the vehicle speed, the higher the noise in the vehicle, so that in order to allow the passengers to hear the audio in the sound zone, when the current vehicle 1000 running speed exceeds a certain threshold, the volume level in each sound zone may be increased appropriately. For example, when the volume levels in the respective sound zones are turned down according to the passenger states, the turning-down width may be reduced in consideration of the faster vehicle speed; for another example, when the volume levels in the respective sound zones are turned up according to the passenger states, the turning-up width may be increased in consideration of a faster vehicle speed.
The volume control method of the vehicle 1000 includes:
recording initial volume before controlling the volume in each sound zone according to the state of the passenger;
and restoring the volume of each sound zone to the initial volume according to the change of the state of the passenger.
Therefore, under the conditions that a passenger calls and chats at ease, the volume can be actively recovered without the indication of the user, and the use experience of the user is improved.
Specifically, the passenger status such as telephone communication, chat, etc. has a starting, in-progress, and ending status, and can be used as a basis for controlling the volume in each sound zone when the passenger status such as telephone communication, chat, etc. is started or in-progress.
