In order to explain the technical means of the present application, the following examples are given below.
Example one
Referring to fig. 1, an embodiment of the present application provides an audio playing control method, as shown in fig. 1, the audio playing control method may include the following steps 101 to 103.
The driving environment information comprises environment volume and the area type of the area where the target vehicle is located currently. The above-mentioned ambient volume is generally the volume of the environment in which the target vehicle is located. In practice, the current location area is usually the current location area of the target vehicle.
In practical applications, the area types may include any one of the following: the user sets a region type, a hospital type, a school type, a research institute type, and a general region type. The area type set by the user is generally a type of an area set by the user, for example, the area set by the user may be a certain cell area. The hospital types mentioned above are generally types corresponding to hospital areas. The school type is generally a type corresponding to a school zone. The types of research units are generally types corresponding to areas of the research units. The general area types described above are typically types other than the types described above.
The target vehicle may be any of various vehicles. The driving environment information is generally information describing the driving environment of the target vehicle. In practice, the driving environment information may include, but is not limited to, an environment volume and a zone type. In practical applications, the driving environment information usually further includes a vehicle speed, a vehicle position, and the like.
In this embodiment, the executing body of the audio playing control method is generally a vehicle, and specifically may be a controller in the vehicle for controlling an audio playing function of the AVAS system. In some application scenarios, the execution subject of the audio playing control method may also be an AVAS system in a vehicle.
In this embodiment, the execution subject may acquire driving environment information of the target vehicle during the driving of the target vehicle. For example, the execution subject may obtain the ambient volume by using a volume sensor, and may also obtain the vehicle position of the target vehicle by using a positioning system on the vehicle, such as a GPS positioning system, so as to obtain the current location area of the target vehicle and the area type of the current location area.
The target analog sound is generally analog sound for the AVAS system to play. The above-mentioned analog sound may be various audio frequencies, for example, an audio frequency including a "protruding sound". The target volume is typically the volume for playback by the AVAS system. In practice, the target simulated sound generally corresponds to the driving environment information, and the target volume generally corresponds to the driving environment information.
Here, the execution subject may determine a target simulated sound currently suitable for the AVAS system of the target vehicle and a volume of the target simulated sound using the driving environment information. As an example, the execution subject may select the associated information corresponding to the driving environment information from a pre-stored associated information set, determine the simulated sound in the associated information as the target simulated sound, and determine the volume in the associated information as the target volume. The associated information in the associated information set may include corresponding driving environment information, analog sound, and volume.
And 103, controlling the acoustic vehicle alarm system to play the target analog sound at the target volume.
Here, after determining the target artificial sound and the target volume, the execution body may control the AVAS system to play the target artificial sound at the target volume. As an example, the execution subject may send an audio playing instruction to the AVAS system, where the audio playing instruction is used to instruct the AVAS system to play the target analog sound at the target volume. Thus, after receiving the audio playing instruction, the AVAS system can play the target analog sound at the target volume.
The audio playing control method provided by the embodiment can select the target analog sound and the target volume matched with the driving environment information of the target vehicle, and control the AVAS system to play the target analog sound at the target volume, so that the audio and the volume of the audio played by the AVAS system can be flexibly and effectively controlled, and the method is more intelligent and is beneficial to improving the user experience.
In some optional implementation manners of this embodiment, the determining a target simulated sound of an AVAS system in a target vehicle and a target volume of the target simulated sound according to driving environment information may include the following steps: firstly, the analog sound corresponding to the area type of the current area is determined as the target analog sound. And then, determining the volume of the target analog sound according to the environment volume to obtain the target volume.
Here, the area of each area type may correspond to an analog sound. In practical application, the corresponding analog tones can be set in advance for the region of each region type. In this way, when the vehicle travels to the area corresponding to the area type, the AVAS system can prompt the surrounding pedestrians with corresponding simulated sounds.
Here, the execution body may determine the analog sound corresponding to the region type of the current region as the target analog sound. Then, the execution subject may determine the target volume using the ambient volume. For example, the execution subject may calculate the target volume by substituting the ambient volume into a preset volume calculation formula. The volume calculation formula may be a formula for calculating the volume, and as an example, the volume calculation formula may be M = H + C, where M is the target volume, H is the ambient volume, and C is a constant, for example, C may be 20.
In this embodiment, the target simulated sound is determined by the area type of the area where the target vehicle is currently located, so that different simulated sounds can be played in areas corresponding to different area types, and the user experience can be improved. In addition, the target volume is determined by adopting the environment volume, so that the analog sound can be played at different volumes under the condition of corresponding to different environment volumes, for example, the analog sound can be played at a higher volume when the environment volume is higher, namely in a noisy scene of an external environment, and the analog sound can be played at a lower volume when the environment volume is lower, namely in a quiet scene of the external environment, so that the analog sound can be played flexibly and effectively, and the user experience can be further promoted.
In some application scenarios, when analog sound and volume are set for a certain region in advance, the region may correspond to the analog sound and volume. In this application scenario, the execution subject may also determine a target simulated sound of the AVAS system in the target vehicle by: when the current area corresponds to the analog sound and the volume, the analog sound corresponding to the current area is determined as the target analog sound of the AVAS system, and the volume corresponding to the current area is determined as the target volume of the AVAS system.
In some optional implementations, the determining the volume of the target analog sound according to the environmental volume to obtain the target volume may include: and determining a volume interval to which the environment volume belongs, and determining the volume corresponding to the determined volume interval as the target volume.
Each volume interval may correspond to a volume. As an example, the volume interval [50, 80] may correspond to a volume of 75. In practice, a plurality of volume sections may be set in advance, and one volume may be set for each volume section.
Here, the execution body may compare the ambient sound volume with each sound volume section, so as to determine a sound volume section to which the ambient sound volume belongs. Then, the execution subject may determine a volume corresponding to the volume section to which the execution subject belongs as the target volume. The present embodiment facilitates a fast and efficient determination of the volume of an AVAS system.
In some optional implementations of various embodiments, before obtaining the driving environment information of the target vehicle, the audio playing control method may further include the following first step and second step.
Step one, according to the vehicle position of the target vehicle, determining the current region of the target vehicle and the region type of the current region.
Here, the execution subject may acquire the vehicle position of the target vehicle using a positioning system on the vehicle, for example, a GPS positioning system. Then, the execution subject may determine the current location area and the area type of the target vehicle by using the vehicle location. In practice, each region may correspond to a region type. As an example, if the vehicle position is within an area range of a certain hospital, the current location area of the target vehicle is the hospital area, and the area type of the current location area is the hospital type.
And step two, determining the existence condition of the movable obstacle of the target vehicle in the driving direction according to the environment image of the target vehicle in the driving direction, and generating obstacle indication information.
Wherein the obstacle indicating information is used to indicate the presence of a movable obstacle in the traveling direction of the target vehicle. In practice, the movable barrier may be a human or other animal. The obstacle indication information may be various information. As one example, the obstacle indicating information may be "person" indicating that the target vehicle has a movable obstacle in the traveling direction, and the movable obstacle is a person. As another example, the above-mentioned obstacle indication information may also be "yes" for indicating that the target vehicle has a movable obstacle in the traveling direction.
Here, the execution body may adopt a camera device, for example, a camera, to capture an environment image of the target vehicle in the traveling direction. The executing entity may then perform obstacle analysis on the environment image, for example, the environment image may be input into a pre-trained obstacle recognition model to obtain an obstacle recognition result, which may indicate the existence of a movable obstacle in the traveling direction of the target vehicle. The obstacle recognition model may be a model obtained by training an initial model (e.g., a Convolutional Neural Network (CNN), a residual error Network (ResNet), etc.) by using a machine learning method based on a training sample.
Finally, the execution body may generate obstacle indication information in conjunction with the presence of the movable obstacle. Specifically, if the presence of a movable obstacle indicates that a movable obstacle is present, obstacle indication information indicating that a movable obstacle is present is generated, and if the presence of a movable obstacle indicates that a movable obstacle is not present, obstacle indication information indicating that a movable obstacle is not present is generated.
The embodiment can timely and accurately determine the driving environment information of the target vehicle in the driving direction.
Example two
With continued reference to fig. 2, the present embodiment provides another audio playing control method, as shown in fig. 2, the audio playing control method may include the following steps 201 to 204.
The driving environment information comprises environment volume and the area type of the area where the target vehicle is located currently.
In this embodiment, the specific operations in step 201 to step 203 are substantially the same as the operations in step 101 to step 103 in the embodiment shown in fig. 1, and are not described herein again.
And 204, when the driving environment information further comprises obstacle indication information and the obstacle indication information indicates a movable obstacle of the target vehicle in the driving direction, adjusting the target volume according to the obstacle distance between the target vehicle and the movable obstacle.
Wherein the adjusted target volume is inversely related to the obstacle distance.
Wherein the obstacle distance is typically the distance between the target vehicle and the movable obstacle. In practice, the above-described executing body may employ a distance measuring device, such as a range finder, an ultrasonic sensor, a laser radar, or the like, to detect the distance between the target vehicle and the movable obstacle.
Wherein the obstacle indicating information is used to indicate the presence of a movable obstacle in the traveling direction of the target vehicle. In practice, the movable barrier may be a human or other animal. The obstacle indicating information may be various information, for example, "person" may indicate that the target vehicle has a movable obstacle in the traveling direction, and the movable obstacle is a person. The obstacle indication information may also be "yes" for indicating that the target vehicle has a movable obstacle in the traveling direction.
In this embodiment, when the obstacle indication information indicates a movable obstacle in the traveling direction of the target vehicle, the execution main body may adjust the volume of the audio played by the AVAS system by using the distance between the target vehicle and the movable obstacle. For example, the target volume may be turned down when the obstacle distance is large, or may be turned up when the obstacle distance is small.
The method provided by the embodiment can prompt the existence of the target vehicle with the larger and larger volume when the target vehicle approaches the movable barrier, for example, the target vehicle approaches a pedestrian, so that the movable barrier can find the vehicle which is driven more easily, the traffic safety can be ensured, and the user experience is improved.
In some optional implementation manners of this embodiment, the audio playing control method may further include the following steps: when the region setting operation is detected, the region set by the region setting operation is determined as the user-set region.
The area setting operation is generally an operation for setting an area. In practice, the region setting operation may be one operation or a combination of a plurality of operations. As an example, the region setting operation may be an operation of clicking a "confirm region setting" button, inputting the region center coordinates, and finally inputting the coordinates of a plurality of boundary points of the region. The area setting operation may be an operation of drawing a closed curve in the map area to be presented.
Here, the execution body may detect the region setting operation through a sensor, for example, a pressure sensor. Then, the execution body may determine the closed region set by the region setting operation as a user-set region. The area type of the user-set area is a user-set area type.
In this embodiment, the user can set some areas to realize that the vehicle can be played with the simulated sound and the volume expected by the user when the vehicle travels to the area, which is helpful for further improving the user experience.
In some optional implementation manners of this embodiment, the audio playing control method may further include the following steps: and when the analog sound selection operation aiming at the target area is detected, determining the analog sound and the volume selected by the analog sound selection operation as the analog sound and the volume corresponding to the target area.
Wherein the target area is an area of any area type. In practice, the target area may be a certain area, or an area of a certain area type. That is, the user may set the corresponding analog sound and volume for a certain region, or may set the corresponding analog sound and volume for all regions of a certain region type.
The above-mentioned analog sound selecting operation is usually an operation of selecting analog sound and volume. In practice, the analog sound selecting operation may be implemented as an operation of selecting an analog sound from an analog sound list, or an operation of requesting a certain analog sound from a target device through a network. Wherein, the analog sound in the analog sound list has volume. The target device may be a user terminal or a server. The target device may send the corresponding analog sound to the execution main body when receiving the request, so that the execution main body may select the analog sound as the analog sound corresponding to the target area and determine a default volume as the volume corresponding to the target area.
Here, the execution subject may detect the analog tone selection operation of the user with respect to the target area through the sensor. Then, the executing body can determine the analog sound and the volume selected by the analog sound selecting operation as the analog sound and the volume corresponding to the target area.
According to the embodiment, the user can set the analog sound and the volume of each area individually, so that when the vehicle runs to the target area, the AVAS system of the vehicle can play audio with the analog sound and the volume expected by the user, and the user experience can be further improved.
