Description

Technical Field

[0001] This application relates to the field of new energy vehicle technology, and in particular to a vehicle communication control method, device and readable storage medium. Background Technology

[0002] Currently, the typical vehicle control method for in-vehicle calling functions involves a simple Bluetooth connection between the vehicle's infotainment system and the user's mobile phone or other terminal. This transmits the user's call signal to the infotainment system, allowing the user to answer or hang up calls. However, this conventional call operation fails to protect the user's call privacy. Therefore, existing vehicle call control methods suffer from technical issues such as low privacy protection levels. Summary of the Invention

[0003] This application provides a vehicle call control method, apparatus, and readable storage medium to address technical problems such as low privacy protection levels in the prior art.

[0004] A first aspect of this application provides a vehicle communication control method. The vehicle includes a communication module, an audio system, and multiple seats. The communication module is used to connect to a communication terminal outside the vehicle, and each seat is equipped with a headrest speaker. The method includes: When the communication module detects that the communication terminal has initiated a call, it determines the target seat of the passenger using the communication terminal among multiple seats. The target seat is any one of the multiple seats. Control the headrest speakers of the target seat to output audio to the communication terminal; Obtain the preset volume range corresponding to the target seat, and adjust the volume of the headrest speaker of the target seat to the preset volume range; During a call at the communication terminal, the headrest speakers of non-target seats are controlled to output a cancellation wave. Non-target seats are those other than the target seat among multiple seats. The cancellation wave is used to shield the audio output of the headrest speakers of the target seat.

[0005] The vehicle call control method in this embodiment, when detecting that the communication terminal has initiated a call, determines the target seat where the passenger using the communication terminal is located, activates the headrest speaker on the target seat to output the audio of the communication terminal, and adjusts the volume of the headrest speaker on the target seat to a safe volume range, thereby achieving directional and quantitative audio output for the passenger and ensuring the passenger's privacy.

[0006] Meanwhile, when passengers are making calls, the headrest speakers of non-target seats output cancellation waves. These cancellation waves can precisely cancel the audio from the headrest speakers of the target seats, limiting the audio propagation distance of the target seats' headrest speakers and preventing the audio from propagating too far. This prevents the leakage of passengers' call privacy and further enhances the level of passenger privacy protection.

[0007] A second aspect of this application provides a vehicle communication control device. The vehicle includes a communication module, an audio system, and multiple seats. The communication module is used to connect to an external communication terminal. Each seat is equipped with a headrest speaker. The device includes: The determination module is used to determine the target seat of the passenger using the communication terminal among multiple seats when the communication module detects that the communication terminal has initiated a call. The target seat is any one of the multiple seats. The first control module is used to control the audio output of the communication terminal from the headrest speaker of the target seat; The acquisition module is used to acquire the preset volume range corresponding to the target seat and adjust the volume of the headrest speaker of the target seat to the preset volume range; The second control module is used to control the audio system to output a cancellation wave to the target seat during a call at the communication terminal. The cancellation wave is used to limit the audio propagation distance of the headrest speaker in the target seat.

[0014] In some embodiments, such as Figure 1 As shown, an embodiment of this application provides a vehicle communication control method, including: Step S101: When the communication module detects that the communication terminal has initiated a call, the target seat of the passenger using the communication terminal is determined from among multiple seats. Step S102: Control the headrest speaker of the target seat to output audio to the communication terminal; Step S103: Obtain the preset volume range corresponding to the target seat, and adjust the volume of the headrest speaker of the target seat to the preset volume range; Step S104: During a call at the communication terminal, control the headrest speaker output of the non-target seat to eliminate the wave.

[0015] In this embodiment, a vehicle communication control method is proposed. The vehicle includes a communication module, an audio system, and multiple seats. The communication module is used to connect to a communication terminal outside the vehicle. Each seat is equipped with a headrest speaker. The vehicle's communication module is a module used to connect to a communication terminal outside the vehicle. The vehicle's audio system is a comprehensive in-vehicle device that integrates sound playback, signal processing, and acoustic design. Its core function is to provide drivers and passengers with a high-quality audio experience.

[0016] For example, a vehicle seat refers to the spatial location where the vehicle's seats are situated. Vehicle seats are not only the core carrier of driving and riding comfort but also a key component of the vehicle's passive safety system. Seats need to provide good support and adjustability during daily use, while effectively protecting occupant safety in a collision.

[0017] For example, a vehicle may include four seats, each equipped with a headrest speaker. The headrest speaker integrates a speaker inside the headrest to achieve directional sound for navigation, calls, or music, which not only ensures driving safety but also enhances the privacy and comfort of the vehicle.

[0018] For example, the communication module can be an in-vehicle Bluetooth module. The in-vehicle Bluetooth module is a core component in modern cars that enables wireless connectivity and intelligent interaction. The in-vehicle Bluetooth module seamlessly connects the vehicle with smart devices such as mobile phones through the Bluetooth protocol. It mainly serves high-frequency driving scenarios such as calls, music playback, navigation information synchronization, and voice control, aiming to improve driving safety and driving experience.

[0019] When the communication module detects that the communication terminal has initiated a call, it determines the target seat of the passenger using the communication terminal among multiple seats, where the target seat is any one of the multiple seats.

[0020] For example, the communication terminal can specifically be a mobile phone, headset, or other device.

[0021] For example, the seat of the passenger making a call using a communication terminal is identified as the target seat.

[0022] For example, when the communication module detects that the communication terminal has connected and initiated a call, the vehicle's privacy call mode can be triggered.

[0023] For example, the communication module is integrated into the vehicle's onboard host and has the functions of device connection recognition and call audio acquisition. It can associate Bluetooth-connected devices with corresponding seats and simultaneously synchronize call audio data to the algorithm module in real time.

[0024] After identifying the target seat, activate the headrest speaker of the target seat and control the headrest speaker of the target seat to output audio to the communication terminal.

[0025] For example, the headrest speakers of the target seat can directionally output audio to passengers using communication terminals, enhancing passenger privacy and comfort.

[0026] Obtain the preset volume range corresponding to the target seat, where the preset volume range is the private volume range of the target seat.

[0027] For example, the preset volume range may specifically be 60 dB to 80 dB.

[0028] For example, the preset volume range can be manually adjusted by the passenger, increasing the flexibility of using the headrest speakers.

[0029] Adjust the volume of the headrest speaker in the target seat to the preset volume range.

[0030] For example, adjusting the volume of the headrest speaker to a preset volume range can be adapted to the range of hearing of the person making the call.

[0031] For example, headrest speakers allow passengers to answer / make calls without holding their phones, improving passenger comfort.

[0032] For example, the headrest speaker can integrate an in-vehicle voice assistant, supporting voice commands such as "answer a call" and "make a call," reducing manual intervention and improving safety.

[0033] During a call at the communication terminal, the headrest speakers of non-target seats are controlled to output a cancellation wave. Non-target seats are those other than the target seat among multiple seats. The cancellation wave is used to shield the audio output of the headrest speakers of the target seat.

[0034] For example, during a call at the communication terminal, the vehicle's audio system is activated, and the audio system is controlled to output a cancellation wave to the target seat.

[0035] For example, a vehicle's audio system may include door speakers and roof speakers. Door speakers form the foundation of the vehicle's sound field and undertake the main sound-emitting task. The doors are the core installation area for door speakers because of their moderate space and proximity to the passengers' ears, making them the "main battleground" for constructing a three-dimensional vehicle sound field. Roof speakers are used to expand dimensions and create a three-dimensional sound field. Roof speakers are mainly used to complete the longitudinal sound field, enabling the vehicle to achieve a panoramic sound effect and improving the passenger's immersive experience.

[0036] For example, during a call at the communication terminal, the vehicle's door speakers and roof speakers are activated simultaneously, and the door speakers and roof speakers are controlled to output a cancellation wave to the target seat. The cancellation wave can prevent the audio from the headrest speakers of the target seat from propagating too far, thus avoiding the leakage of the passenger's call privacy and improving the level of passenger privacy protection.

[0037] For example, the vehicle's audio system can dynamically adapt and adjust, monitoring changes in passenger status (such as passengers getting on and off the vehicle, seat movement) and call status (such as changes in call volume, fluctuations in voice frequency) in real time, and then adjusting accordingly: if the number of passengers decreases to 1, the cancellation wave output is turned off and the default audio output mode is restored; if the passenger position changes, the non-target seat is repositioned and the cancellation wave output channel and parameters are adjusted; if the call volume fluctuates, the cancellation wave amplitude is optimized synchronously to maintain the cancellation effect.

[0038] The vehicle call control method in this embodiment, when detecting that the communication terminal has initiated a call, determines the target seat where the passenger using the communication terminal is located, activates the headrest speaker on the target seat to output the audio of the communication terminal, and adjusts the volume of the headrest speaker on the target seat to a safe volume range, thereby achieving directional and quantitative audio output for the passenger and ensuring the passenger's privacy.

[0039] Meanwhile, when passengers are making calls, the headrest speakers of non-target seats output cancellation waves. These cancellation waves can precisely cancel the audio from the headrest speakers of the target seats, limiting the audio propagation distance of the target seats' headrest speakers and preventing the audio from propagating too far. This prevents the leakage of passengers' call privacy and further enhances the level of passenger privacy protection.

[0040] In addition, the vehicle call control method of this embodiment solves the problem that the prior art cannot dynamically adapt to changes in passenger status and call status. It detects the number and location of passengers in the vehicle and call audio parameters in real time, and dynamically adjusts the headrest speaker output and wave cancellation parameters to ensure a balance between privacy and sound quality in different scenarios.

[0041] The vehicle call control method in this embodiment also solves the problem of scene conflict caused by volume adjustment. Non-target seats cancel out the leakage sound by eliminating the need to deliberately reduce the volume of other audio playback, thus ensuring a personalized experience for all passengers in the vehicle.

[0042] In some embodiments, this application provides a vehicle communication control method, which determines a target seat for a passenger using a communication terminal among multiple seats, including: Determine the signal strength between the communication module and the communication terminal; Determine the first distance between the communication module and the communication terminal based on the signal strength; Based on the first distance, determine the first seat among multiple seats; Set the first seat as the target seat.

[0043] In this embodiment, the signal strength between the communication module and the communication terminal is obtained, wherein the signal strength is used to represent the signal transmission status between the communication module and the communication terminal.

[0044] For example, the signal strength of a communication module is affected by various factors, and its normal range is usually measured by the received signal strength indicator. An absolute value less than 70dBm (i.e., greater than -70dBm) is considered normal signal strength, and ideally it should be maintained above -50dBm. The closer the signal is to 0dBm, the stronger it is. If the signal strength is below -70dBm, problems such as unstable connection, audio stuttering, or disconnection may occur.

[0045] Based on the signal strength, a first distance is determined between the communication module and the communication terminal, wherein the first distance is the distance between the communication module and the communication terminal.

[0046] For example, the signal strength of the communication module is mainly affected by distance. Therefore, based on the correspondence between signal strength and distance, a first distance between the communication module and the communication terminal can be determined. Based on the first distance, multiple seats can be located by distance, and then the first seat among the multiple seats can be determined and set as the target seat. The first seat is the seat determined by positioning based on the signal strength.

[0047] For example, inside a vehicle, the distance difference between the communication module and multiple seats is fixed. The first seat can be determined by performing distance positioning on the multiple seats based on the first distance.

[0048] In some embodiments of this application, a vehicle communication control method is provided, wherein the vehicle further includes a camera. After determining a first seat among a plurality of seats based on a first distance, the method further includes: Control the camera to collect image data inside the vehicle; The image data is identified to determine the second seat occupied by the passenger using the communication terminal among multiple seats; If the second seat is the same as the first seat, set the second seat as the target seat.

[0049] In this embodiment, the vehicle also includes a camera for capturing images of the vehicle's interior.

[0050] For example, the camera can specifically be a driver monitoring camera, a key safety device in modern smart cars used to monitor the driver's condition in real time. It uses infrared imaging and AI algorithms to accurately identify high-risk driving behaviors such as fatigue and distraction, and issues warnings before an accident occurs.

[0051] For example, the camera may specifically be a cabin surround view camera, installed in the center of the roof or above the center console, with passenger facial recognition and seat occupancy detection functions, a resolution of not less than 1080P, and a frame rate of ≥30fps, used to accurately identify the number of passengers in the vehicle and the seat position of each passenger.

[0052] The system controls a camera to capture image data of the vehicle's interior, which is a real-time image of the vehicle's interior.

[0053] For example, the image data can be two-dimensional images. Two-dimensional images require less time to acquire and process, making them suitable for rapid identification and dynamic monitoring. Two-dimensional images have a smaller data volume and a higher pixel density per unit area, enabling them to present more detailed structural information.

[0054] For example, the image data can be a three-dimensional image. By adding a depth dimension (z-axis), a three-dimensional image can realistically reproduce the spatial structure of an object. The target can be rotated and scaled from multiple angles, significantly improving the ability to understand anatomical structures.

[0055] Image data is identified to determine the second seat occupied by the passenger using the communication terminal among multiple seats, wherein the second seat is the seat determined by image recognition.

[0056] For example, human motion recognition can be performed on image data to identify a passenger making a phone call in the image, and then to determine the passenger's second seat.

[0057] For example, lip reading can be performed on human targets in image data to identify a passenger making a phone call in the image, and then to determine the passenger's second seat.

[0058] If the second seat is the same as the first seat, it means that the second seat and the first seat are the same seat, indicating that the seat identification is accurate, and the second seat is then set as the target seat.

[0059] In some embodiments of this application, a vehicle communication control method is provided, wherein the vehicle further includes a seat sensor, and a second seat is set as the target seat, comprising: The control seat sensor collects the pressure value of the second seat; Determine the seating posture of the passenger in the second seat based on the pressure value; If the passenger's sitting posture in the second seat is the same as the preset sitting posture, the second seat will be set as the target seat.

[0060] In this embodiment, the vehicle also includes seat sensors, which include pressure sensors and posture detection sensors. The seat sensors are integrated into the seat cushion and backrest, and can monitor in real time whether the seat is occupied and the passenger's posture. This complements the data from the in-vehicle camera and improves the accuracy of passenger position recognition.

[0061] For example, a pressure sensor is a device that converts physical pressure signals into electrical signals. Based on the piezoresistive, piezoelectric, or capacitive effects, the resistance, voltage, or capacitance of a material changes when it is subjected to force, thereby outputting a measurable electrical signal.

[0062] For example, the posture detection sensor is used to identify common postures such as standard sitting posture, leaning forward, leaning to the side, and semi-reclining, and to judge the sitting posture by features such as the position of the pressure center and left-right symmetry.

[0063] The control seat sensor collects the pressure value of the second seat, where the pressure value is the pressure value of the second seat when the passenger sits in the second seat.

[0064] For example, the pressure value of the second seat can be accurately monitored by a pressure sensor in the seat sensor.

[0065] The seating posture of the passenger in the second seat is determined based on the pressure value.

[0066] For example, the posture of a passenger in a second seat can be accurately determined by a posture detection sensor in the seat sensor.

[0067] If the passenger's sitting posture in the second seat is the same as the preset sitting posture, it means that the second seat is the target seat and the second seat is set as the target seat.

[0068] For example, the preset sitting posture can be a phone call posture. If the passenger in the second seat has the same sitting posture as the preset posture, it means that the passenger in the second seat is indeed making a phone call, thus ensuring the accuracy of the second seat identification.

[0069] In some embodiments, this application provides a vehicle call control method for obtaining a preset volume range corresponding to a target seat, including: Obtain the size data of the target seat; Based on the size data, determine the communication space for the target seat; Determine the preset volume range based on the call space.

[0070] In this embodiment, the size data of the target seat is obtained, wherein the size data is data representing the specific size of the target seat.

[0071] For example, the size data may specifically include length, width, and height.

[0072] Based on the size data, determine the communication space of the target seat, where the communication space is a safe communication space.

[0073] For example, the call space is a secure call space in which passenger privacy can be prevented.

[0074] Determine the preset volume range based on the call space.

[0075] For example, the call space is proportional to the preset volume range, and the preset volume range can be determined based on the call space.

[0076] In some embodiments, this application provides a vehicle call control method that controls the headrest speaker output of a non-target seat to cancel out echoes, including: Determine the second distance between the non-target seat and the target seat; Based on the second distance, determine the output frequency corresponding to the non-target seat; Acquire the sound wave frequency, phase, and amplitude of the headrest speaker output of the target seat; Based on the sound wave frequency, sound wave phase, and sound wave amplitude, a cancellation wave is generated; Control the headrest speakers of non-target seats to output cancellation waves according to the output frequency.

[0077] In this embodiment, a second distance between the non-target seat and the target seat is determined, wherein the second distance is the distance between the non-target seat and the target seat.

[0078] Based on the second distance, determine the output frequency corresponding to the non-target seat.

[0079] For example, the output power of the audio system is dynamically adjusted based on a second distance between the non-target seat and the target seat to ensure the cancellation effect while avoiding the generation of additional noise.

[0080] For example, the sound wave frequency, sound wave phase, and sound wave amplitude of the headrest speaker output of the target seat are obtained, wherein the sound wave frequency is the frequency of the sound wave output by the headrest speaker, the sound wave phase is the phase of the sound wave output by the headrest speaker, and the sound wave amplitude is the amplitude of the sound wave output by the headrest speaker.

[0081] An elimination wave is generated based on the sound wave frequency, phase, and amplitude.

[0082] Control the headrest speakers of non-target seats to output cancellation waves according to the output frequency.

[0083] For example, the audio acquisition step of the headrest speaker output includes: acquiring the voice audio signal of the caller in real time through the communication module, with the sampling rate set to 44.1kHz, and simultaneously acquiring ambient sound and leaked call sound through a microphone near a non-target seat as a feedback signal.

[0084] For example, the cancellation wave can be specifically an anti-phase cancellation wave. The steps for generating the anti-phase cancellation wave include: based on the acquired call audio signal, the algorithm generates an anti-phase cancellation wave with the same amplitude and opposite phase in real time, and dynamically adjusts the frequency, amplitude and phase of the cancellation wave according to the ambient sound feedback to ensure accurate cancellation with the leaked sound. For example, the dynamic calibration step of wave cancellation includes: continuously optimizing wave cancellation parameters through a minimum mean square error algorithm to compensate for deviations caused by audio hardware delays and acoustic reflections in the vehicle interior, ensuring stable cancellation effect.

[0085] In some embodiments of this application, a vehicle call control method is provided. After controlling the headrest speaker output of a non-target seat to cancel the wave, the method further includes: When the communication terminal ends the call, the headrest speakers of the non-target seats stop outputting the cancellation wave.

[0086] In this embodiment, when the communication terminal ends the call, the headrest speakers of the non-target seats are controlled to stop outputting cancellation waves.

[0087] For example, after the call ends, the main control module disables the privacy call mode, the audio system returns to its previous operating state, and the algorithm module goes into standby mode. The main control module uses an automotive chip to integrate various hardware data, run the sound cancellation algorithm, and control the audio system output. It has millisecond-level data processing capabilities to ensure real-time performance.

[0088] In some embodiments, such as Figure 2 As shown, an embodiment of this application provides a vehicle communication control device 200. The vehicle includes a communication module, an audio system, and multiple seats. The communication module is used to connect to an external communication terminal. Each seat is equipped with a headrest speaker. The communication control device 200 includes: The determining module 202 is used to determine the target seat of the passenger using the communication terminal among multiple seats when the communication module detects that the communication terminal has initiated a call. The target seat is any one of the multiple seats. The first control module 204 is used to control the headrest speaker of the target seat to output audio to the communication terminal. The acquisition module 206 is used to acquire the preset volume range corresponding to the target seat and adjust the volume of the headrest speaker of the target seat to the preset volume range; The second control module 208 is used to control the headrest speaker output cancellation wave of non-target seats during a call at the communication terminal. Non-target seats are seats other than the target seats among multiple seats. The cancellation wave is used to shield the audio output of the headrest speaker of the target seat.

[0089] In this embodiment, the vehicle's communication control device 200, upon detecting a communication terminal initiating a call, determines the target seat of the passenger using the communication terminal, activates the headrest speaker on the target seat to output the communication terminal's audio, and adjusts the volume of the headrest speaker to a safe and controlled level. This achieves directional and quantitative audio output for the passenger, ensuring the passenger's privacy.

[0090] Meanwhile, when passengers are making calls, the headrest speakers of non-target seats output cancellation waves. These cancellation waves can precisely cancel the audio from the headrest speakers of the target seats, limiting the audio propagation distance of the target seats' headrest speakers and preventing the audio from propagating too far. This prevents the leakage of passengers' call privacy and further enhances the level of passenger privacy protection.

[0091] In addition, the vehicle communication control device 200 in this embodiment solves the problem that the prior art cannot dynamically adapt to changes in passenger status and call status. It detects the number and location of passengers in the vehicle and call audio parameters in real time, and dynamically adjusts the headrest speaker output and wave cancellation parameters to ensure a balance between privacy and sound quality in different scenarios.

[0092] The vehicle communication control device 200 in this embodiment also solves the problem of scene conflict caused by volume adjustment. Non-target seats cancel out the leakage sound by eliminating the need to deliberately reduce the volume of other audio playback, thus ensuring a personalized experience for all passengers in the vehicle.

[0097] In some embodiments of this application, a vehicle communication control device 200 is provided, wherein the second control module 208 is further configured to: Determine the second distance between the non-target seat and the target seat; Based on the second distance, determine the output frequency corresponding to the non-target seat; Acquire the sound wave frequency, phase, and amplitude of the headrest speaker output of the target seat; Based on the sound wave frequency, sound wave phase, and sound wave amplitude, a cancellation wave is generated; Control the headrest speakers of non-target seats to output cancellation waves according to the output frequency.

[0098] In some embodiments of this application, a vehicle communication control device 200 is provided, wherein the second control module 208 is further configured to: When the communication terminal ends the call, the headrest speakers of the non-target seats stop outputting the cancellation wave.
