To facilitate understanding of the volume adjusting method disclosed by the present invention, the present invention provides several in-vehicle scenario modes, and provides a corresponding audio playing volume adjusting and controlling strategy for each in-vehicle scenario mode, that is, step S103 specifically includes:
(1) rest scene of passengers in vehicle
And when the current in-vehicle scene mode is the in-vehicle passenger rest scene, reducing the audio playing volume of the passenger rest area to a first audio playing value.
The value of the first audio playing value in this embodiment is determined according to actual needs, and is preferably 0.
In the vehicle driving process, when the vehicle-mounted audio equipment plays audio, for example, music and navigation are played, the state of a secondary driver and the state of a rear passenger are identified according to the environment image in the vehicle collected by the camera in the vehicle, and when the passenger in the vehicle has a rest, the audio playing volume in the rest area of the passenger is reduced to a first audio playing value.
The passenger resting area in the present embodiment includes: a copilot area and a rear row area. When only the passengers on the back row have a rest, the audio playing volume of the back row area can be only reduced to a first audio playing value; when the passenger in the front row and the passenger in the rear row both have a rest, the audio playing volume at other positions is reduced to the first audio playing value except the audio playing volume at the driver side. In practical application, white noise can be played to help sleep.
When the vehicle is provided with the headrest sound box, the audio can be played through the headrest sound box on the main driving side, and the audio playing volume of other positions is reduced to a first audio playing value.
The camera includes in the car in this embodiment: an OMS (Occupant Monitoring Sensor) camera and a DMS (Driver Monitoring System) camera.
When the current in-vehicle scene mode is a preset volume increasing scene, increasing the audio playing volume of the passenger rest area from the first audio playing value to the volume corresponding to the normal state in a gradual-up mode;
wherein the predicted volume up mode is: the vehicle interior passenger wakes up or the remaining distance from the current position of the vehicle to the destination is a preset distance.
Specifically, when the in-vehicle passenger is identified to wake up according to the in-vehicle camera acquiring the in-vehicle environment image, the volume corresponding to the normal state can be increased from the first audio playing value in a gradual-increase manner after the passenger wakes up for a preset time period, for example, 1 minute.
The normal state in this embodiment refers to a state when none of the occupants in the vehicle is at rest.
And when the remaining distance from the current position of the vehicle to the destination is determined to be a preset distance according to the navigation route, the volume corresponding to the normal state is increased from the first audio playing value in a gradual-up mode so that the passenger can wake up in advance and is ready to get off when the vehicle reaches the destination.
The value of the preset distance is determined according to actual needs, and the invention is not limited herein.
(2) In-vehicle passenger call receiving and making scene
When the current in-vehicle situation mode is the situation that a passenger in the vehicle makes a call, the in-vehicle audio playing volume is reduced to a second audio playing value;
and when the passenger in the vehicle stops making a call, increasing the volume of the audio playing in the vehicle from the second audio playing value to the volume corresponding to the normal state in a gradual-up mode.
The value of the second audio playing value may be the same as or different from the value of the first audio playing value, and the specific value is determined according to actual needs, which is not limited herein.
In practical application, when the in-vehicle signal detector detects that a telephone signal is accessed in the vehicle, the in-vehicle audio playing volume is reduced, and the in-vehicle atmosphere lamp can be controlled to flicker to remind a passenger in the vehicle of the telephone signal access.
And determining whether the passengers in the automobile make calls or not according to the image of the environment in the automobile acquired by the camera in the automobile, and continuously reducing the audio playing volume in the automobile to a second audio playing value when the passengers in the automobile make calls. When the fact that a telephone signal is connected into the vehicle and a passenger in the vehicle does not answer the telephone is detected, the reduced volume of the audio playing in the vehicle can be recovered to the volume corresponding to the normal state after a preset time period.
In the process of answering and making a call of the passengers in the automobile, the environment images in the automobile are collected in real time, and when the passengers in the automobile are determined to stop answering and making a call according to the environment images in the automobile collected by the camera in the automobile, the audio playing volume can be controlled to enter playing.
(3) In-vehicle occupant communication scene
When the current in-vehicle situation mode is the in-vehicle passenger communication situation, the volume evasion function is started;
when the communication of the passengers in the vehicle is finished, the volume evasion function is closed, and the volume of the audio playing in the vehicle is restored to the volume corresponding to the normal state;
wherein, the communication scene of the passengers in the vehicle is as follows: human voice and motion interaction between the occupants is detected.
The volume evasion function in this embodiment means: when a person speaks or does not speak, the sound card can automatically adjust the volume of the background music. The volume evasion function has the effect of gradually entering and gradually exiting.
Specifically, when the vehicle-mounted audio device plays audio, if the audio playing volume is large, passengers in the vehicle need to speak loudly or even shout when communicating with each other.
According to the invention, when the vehicle-mounted audio equipment plays audio, the voice is detected in real time according to the microphone in the vehicle, the interaction action among the passengers in the vehicle is detected in real time according to the camera in the vehicle, and when the current communication scene of the passengers in the vehicle is determined according to the interaction action between the voice and the passengers in the vehicle, the volume evasion function is started. When the communication of the passengers in the vehicle is finished, for example, when the voice is not detected in a preset time period, the volume dodging function is turned off, and the volume of the audio playing in the vehicle is restored to the volume corresponding to the normal state.
(4) Communication scene between people inside and outside vehicle
When the current in-vehicle situation mode is a communication situation of people inside and outside the vehicle, the in-vehicle audio playing volume is reduced to a third audio playing value;
when the communication between the personnel inside and outside the vehicle is finished, the audio playing volume inside the vehicle is restored to the volume corresponding to the normal state from the third audio playing value;
wherein, the communication scene of the personnel inside and outside the vehicle is as follows: playing audio in the vehicle, wherein the audio playing volume is greater than the preset audio volume, the vehicle speed is reduced to 0, the vehicle side window is opened, and the direction pointed by the sight line or the head of a passenger in the vehicle faces the opened vehicle side window; alternatively, the vehicle speed is reduced to 0, the door is opened, and the line of sight or the head of the occupant faces the opened door or the alighting.
In this embodiment, when the volume of the in-vehicle audio is higher than the preset volume, the in-vehicle audio will inevitably affect the communication between the in-vehicle and the outside, so that when the current in-vehicle scene mode is determined to be the in-vehicle and the outside communication scene, the in-vehicle audio playing volume is reduced to the third audio playing value to ensure the smooth communication between the in-vehicle and the outside.
The value of the third audio playing value is determined according to actual needs, and the invention is not limited herein.
