[0032] To make the above-mentioned objects, features, and advantages of this disclosure more apparent and understandable, the disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0033] When playing audio from a vehicle to pedestrians or other objects, especially when playing audio from a vehicle to people outside the vehicle, the same volume is usually used in all locations. However, the positions of pedestrians and other objects outside the vehicle may change, resulting in the sound volume being insufficient for them.

[0034] Based on this, some embodiments of this disclosure provide a method, apparatus, device, vehicle, and medium for controlling the volume of sound emitted by a vehicle.

[0035] Referring to FIG1, a flowchart of a method for controlling the volume of a vehicle's sound according to some embodiments of the present disclosure is shown. In some embodiments, the vehicle may be a car equipped with at least one motor module, such as an electric vehicle or a hybrid vehicle. The motor module is a motor module used to drive the vehicle. The motor module may include a motor and a controller. The motor may be an asynchronous motor, a synchronous motor, or an electrically excited motor.

[0036] In practical applications, a vehicle can be equipped with at least two motor modules, such as two motor modules, three motor modules, or four motor modules. At least two motor modules can be installed in different positions on the vehicle, such as at least two motor modules installed in the corresponding positions of the front right wheel, front left wheel, rear right wheel, and rear left wheel.

[0037] As shown in Figure 2, the motor module may include a front right electric drive assembly and a front left electric drive assembly, which are respectively connected to the power battery. As shown in Figure 3, the motor module may include a rear right electric drive assembly and a rear left electric drive assembly, which are respectively connected to the power battery. As shown in Figure 4, the motor module may include a front electric drive assembly and a rear electric drive assembly, which are respectively connected to the power battery.

[0038] For example, the method may include steps 101-103 as follows.

[0039] Step 101: Obtain the location information of the target object;

[0040] In some embodiments of this disclosure, the target object is an object located outside the vehicle cabin, such as a pedestrian outside the vehicle cabin, and obtaining the location information of the target object includes: collecting the location information of the target object through sensors.

[0041] In some embodiments of this disclosure, the sensor includes one or more of the following: a camera system, an infrared thermal imaging system, an audio microphone pickup system, and a radar system.

[0042] In practical applications, the location information of the target object can be collected through sensors such as camera systems, infrared thermal imaging systems, audio microphone pickup systems, and radar systems.

[0043] Step 102: Based on the location information of at least one motor module of the vehicle and the location information of the target object, determine the target motor module from the at least one motor module.

[0044] In practical applications, the motor module has position information. For example, at least one motor module is set at the corresponding positions of the front right wheel, front left wheel, rear right wheel, and rear left wheel. The position information of the motor module can be compared with the position information of the target object to determine the target motor module with the matching position.

[0045] In some embodiments of this disclosure, determining a target motor module from the at least one motor module based on the location information of the vehicle's motor module and the location information of the target object includes: determining a motor module that meets the target conditions as the target motor module.

[0046] In some embodiments, at least one motor module may include one to four motor modules, and the target motor module may be some or all of the motor modules therein, such as the target motor module may also include one to four target motor modules.

[0047] The target conditions include at least one of the following: the target motor module and the target object are located on the same side of the vehicle, or the target motor module is located within a preset distance range of the target object.

[0048] For example, the target object being located on the same side of the vehicle can be: if the target object is on the left side of the vehicle, then the target motor module is the front left wheel and the rear left wheel; if the target object is on the right side of the vehicle, then the target motor module is the front right wheel and the rear right wheel.

[0049] Step 103: Control the sound volume of the target motor module.

[0050] The distance to objects outside the vehicle is identified by cameras, infrared, audio microphones, or radar devices. Based on the distance of the objects, the volume of each motor module is automatically adjusted to achieve a wider stereo range, ensuring that the sound playback volume and other effects are basically consistent across different locations of objects outside the vehicle, and expanding the stereo range according to the location of the objects outside the vehicle.

[0051] In some embodiments of this disclosure, the method further includes: controlling the volume of the remaining motor modules; the number of target motor modules is less than the number of motor modules in the vehicle, and the remaining motor modules are the motor modules in the vehicle other than the target motor modules.

[0052] In addition to controlling the volume of the target motor module, the volume of the remaining motor modules can also be controlled. For example, if there are four motor modules, the target motor modules can be one, two, or three, and the others can be the remaining motor modules.

[0053] In some embodiments of this disclosure, controlling the sound volume of the target motor module includes: determining the distance information between the target motor module and the target object based on the position information of the vehicle's motor module and the position information of the target object; and controlling the sound volume of the target motor module based on the distance information.

[0054] In some embodiments of this disclosure, controlling the sound volume of the target motor module based on the distance information includes: when the target motor module includes a single target motor module, controlling the sound volume of the target motor module based on the distance information corresponding to the target motor module, on the basis of a preset volume.

[0055] In some embodiments of this disclosure, when the target motor module includes a single target motor module, the sound output volume of the target motor module is controlled based on a preset volume according to the distance information corresponding to the target motor module. This includes: converting the distance information corresponding to the target motor module into a target volume; the magnitude of the target volume is negatively correlated with the magnitude of the distance information; and comparing the target volume with the preset volume, and based on the comparison result, increasing, decreasing, or maintaining the sound output volume of the target motor module based on the preset volume.

[0056] When the target motor module includes a target motor module, the distance information can be directly converted into the target volume, and then the volume difference between the target volume and the preset volume can be calculated. Then, the preset volume can be increased, decreased, or kept unchanged based on the volume difference.

[0057] In some embodiments of this disclosure, controlling the sound volume of the target motor module based on the distance information includes: when the target motor module includes multiple target motor modules, determining a distance difference based on the distance information corresponding to the multiple target motor modules, and controlling the sound volume of the multiple target motor modules based on the distance difference.

[0058] In some embodiments of this disclosure, controlling the sound volume of the plurality of target motor modules based on the distance difference includes: when the distance difference is within a preset difference range, controlling the sound volume of the target motor module farthest from the target object to increase, and controlling the sound volume of the target motor module closest to the target object to decrease or remain unchanged; when the distance difference is less than the minimum value of the preset difference range, controlling the sound volume of the plurality of target motor modules to remain unchanged; and when the distance difference is greater than the maximum value of the preset difference range, controlling the sound volume of the plurality of target motor modules to remain unchanged.

[0059] In practical applications, the location of the center of a person or crowd (i.e., an object outside the vehicle) is identified through a camera system, infrared thermal imaging system, audio microphone pickup system, or radar system. The distance between the object outside the vehicle and the motor is calculated based on the location of the object outside the vehicle, and then the volume is controlled.

[0060] For example, if the distance between the person and motor 1 is calculated to be A, and the distance between the person and motor 2 is calculated to be B, the steps to adjust the volume ratio of the two motors are as follows.

[0061] When the identified person or group of people is only in a single direction (such as left, right, front, or back), the steps for adjusting the two motor modules closest to that direction include: when the absolute value |AB| < M1, no adjustment is made to the sound volume; when M1 ≤ |AB| ≤ M2, the sound volume is adjusted with weights, increasing the volume of the motor module farther from the person. If the increased volume weight causes the motor to exceed the volume amplitude range of the sound, the maximum amplitude value is maintained for control; when |AB| > M2, the sound volume is no longer adjusted, and the previous volume state is maintained.

[0062] Where M1 and M2 are the minimum and maximum values ​​of the preset difference range.

[0063] In some embodiments of this disclosure, the energy of the motor module for playing music is allocated based on the position of a person or group of people. The music moves with the person, achieving an intelligent allocation of music volume and a better stereo sense of position and spatial reproduction effect.

[0064] In some embodiments, by utilizing the spatial arrangement of at least two motors, the decoded data of at least two channels is transmitted to two sets of motor modules. After receiving the playback command, the two sets of motor modules simultaneously start the playback action, allowing the two motors to play the audio signals of the two channels at the same time, which can form a special music surround sound.

[0065] In some embodiments, one set of motor modules plays music, while the other set plays background sounds of nature, simulating music playback in scenes such as waterfalls, forests, and rain, creating an immersive experience. This allows for the perception of beautiful stereo sound over a larger area, achieving the effect of at least two motors playing stereo, thus reproducing the sense of position and space in the sound.

[0066] In some embodiments of this disclosure, controlling the sound volume of the target motor module includes: acquiring volume control parameters and an electrical control signal, and controlling the electrical control signal according to the volume control parameters.

[0067] The volume control parameter is the amplitude of increasing or decreasing the sound volume, and the electrical control signal is the electrical control parameter obtained by converting the audio data to be played to control the target motor module to produce sound.

[0068] For the electrical control signal, after obtaining the audio signal, the audio signal can be converted into an electrical control signal. Then, the electrical control signal can be used to perform field-oriented control on the motor in the motor module. Through field-oriented control, the electromagnetic vibration in the motor can emit a sound corresponding to the audio signal.

[0069] In practical applications, a field-oriented control (FOC) vector control system can be pre-established, such as a rotor field-oriented FOC vector control system based on a permanent magnet synchronous motor, a rotor field-oriented FOC vector control system based on an asynchronous motor, or a rotor excitation field-oriented FOC vector control system based on an electrically excited synchronous motor.

[0070] For a vector control system, the first electrical control signal can be converted into a component perpendicular to the rotor magnetic field and a component parallel to the rotor magnetic field by combining the rotor position in the motor. Then, the rotor in the motor can be controlled by the components perpendicular to the rotor magnetic field and the components parallel to the rotor magnetic field, thereby realizing the field-oriented control of the motor.

[0071] In some embodiments of this disclosure, controlling the electrical control signal according to the volume control parameters includes controlling at least one of the amplitude or phase of the electrical control signal according to the volume control parameters.

[0072] In some embodiments of this disclosure, by obtaining the location information of the target object, determining the target motor module from the motor modules based on the location information of the vehicle's motor module and the location information of the target object, and controlling the sound volume of the target motor module, the sound volume is controlled according to the location of the object when the vehicle's motor module emits sound, thereby improving the sound emission effect of the vehicle.

[0073] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that the embodiments of this disclosure are not limited to the described order of actions, because according to the embodiments of this disclosure, some steps can be performed in other orders or simultaneously.
