Description

Technical Field

[0001] The present invention relates to the field of interactive technology, and in particular to an interactive method, a first device, a second device, a server and a third device, an interactive system, a vehicle and a computer-readable storage medium. Background Art

[0002] In the related art, electronic interactive devices based on sound waves rely on independent sound wave emitting devices. Such electronic interactive devices are separated from the existing devices of the application equipment and require additional devices such as ultrasonic generators and speakers. This separate architecture results in a low degree of device integration. Not only does it require the deployment of multiple additional hardware modules in the application equipment, but it also brings greater system design complexity due to factors such as space, power supply, and environmental interference. At the same time, since these devices are often exposed to the surface of the application equipment, they are easily affected by harsh external environments such as dust, water vapor, and vibration, causing device performance to degrade or even be damaged, further affecting the stability and interactive reliability of the overall system. In addition, the reuse rate of these devices is low and they are only used for sound wave communication. They fail to effectively utilize the existing actuator resources of the application equipment, increasing costs and maintenance complexity. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide an interaction method that can directly utilize motors for acoustic interaction, eliminating the need for additional acoustic wave emitting devices. This method reduces the need for additional hardware equipment, lowers equipment costs, and avoids the risk of damage to additional hardware equipment, thereby improving the reliability of interaction.

[0017] In order to achieve the above-mentioned purpose, the interaction method of the first aspect of the embodiment of the present invention is used for a first device, wherein the first device has a first controller and a first motor, and the interaction method includes: the first controller obtains an interaction request; the first controller controls the first motor to emit a first sound wave signal, and the first sound wave signal contains interaction information, and the interaction information is obtained according to the interaction request.

[0018] According to the interaction method of an embodiment of the present invention, after receiving an interaction request, the first controller controls the operation of the first motor, causing it to begin vibrating and thereby emitting a first sound wave signal of a specific frequency and specific loudness. This signal carries the interaction information, thereby enabling acoustic transmission of information. Because this method directly reuses the first motor already in the first device as the source of the sound wave signal, eliminating the need for an additional dedicated sound wave transmitter (such as a speaker or ultrasonic module), it can effectively reduce reliance on external hardware devices, lowering the overall hardware complexity and cost of the system. Furthermore, since the first motor itself is a standard feature of the first device, its stability and reliability have been fully verified. Its relatively fixed position and strong environmental adaptability make it less susceptible to damage due to external environmental influences. This avoids the risk of damage to independent sound wave transmitters in the prior art, thereby improving the reliability of the interaction.

[0019] In some embodiments, the first controller controls the operation of the first motor by sending a control signal to the first motor, where the control signal includes the transaction information.

[0020] In some embodiments, the control signal is a signal encoded using a preset encoding rule.

[0031] According to the interaction method of an embodiment of the present invention, a second device, through its own second sound wave receiving module, can receive a first sound wave signal generated by the operation of the first motor of the first device. This signal contains interaction information. Specifically, after receiving an interaction request, the first controller controls the operation of the first motor, causing it to vibrate, thereby emitting a first sound wave signal of a specific frequency and loudness. This signal carries the interaction information, thereby enabling acoustic transmission of information. Because this method directly reuses the first motor already in the first device as the source of the sound wave signal, eliminating the need for a dedicated sound wave transmitter (such as a speaker or ultrasonic module), it effectively reduces reliance on external hardware devices, lowering the overall hardware complexity and cost of the system. Furthermore, since the first motor itself is a standard feature of the first device, its stability and reliability have been fully verified. Its relatively fixed position and strong environmental adaptability make it less susceptible to damage due to external environmental influences. This avoids the risk of damage to independent sound wave transmitters in the existing technology, thereby improving the reliability of the interaction.

[0042] In order to achieve the above-mentioned purpose, the interaction method of the third aspect of the embodiment of the present invention is used for a server, and the interaction method includes: receiving interaction information, which is obtained based on a first sound wave signal emitted by a first motor of a first device; obtaining interaction feedback information, which is obtained by interactive processing based on the interaction information; and sending the interaction feedback information.

[0043] According to an interaction method according to an embodiment of the present invention, a server can receive and process interaction information to obtain interaction feedback information. The interaction information is obtained based on a first acoustic wave signal emitted by a first motor of a first device. Specifically, after receiving an interaction request, the first controller controls the first motor to vibrate, thereby emitting a first acoustic wave signal of a specific frequency and loudness. This signal carries the interaction information, thereby enabling acoustic transmission of the information. Because this method directly reuses the first motor already in the first device as the source of the acoustic wave signal, eliminating the need for a dedicated acoustic wave transmitter (such as a speaker or ultrasonic module), it effectively reduces reliance on external hardware devices, lowering the overall hardware complexity and cost of the system. Furthermore, since the first motor itself is a standard feature of the first device, its stability and reliability have been fully verified. Its relatively fixed position and strong environmental adaptability make it less susceptible to damage due to external environmental influences. This avoids the risk of damage to independent acoustic wave transmitters in the prior art, thereby improving the reliability of the interaction.

[0044] In some embodiments, the interaction information includes transaction information.

[0047] In some embodiments, before obtaining the interaction feedback information, the interaction method further includes: receiving authentication information of the first device; obtaining an authentication result, where the authentication result is obtained by authenticating the first device based on the authentication information; and sending the authentication result.

[0048] In some embodiments, the interaction feedback information is obtained by performing interaction processing based on the interaction information after the first device is authenticated.

[0050] According to the interaction method of an embodiment of the present invention, a third device can extract device information containing the first device's identification or attributes by collecting and identifying image information from the first device. This device then generates and transmits authentication information to the second device. This authentication method effectively prevents interception, replay, or tampering attacks, thereby improving transaction security. Furthermore, the acoustic signal containing the interaction information is generated by the first motor in the first device. Specifically, after receiving the interaction request, the first controller controls the first motor to vibrate, thereby emitting a first acoustic signal of a specific frequency and loudness. This signal carries the interaction information, thereby enabling acoustic transmission of information. Because this method directly reuses the first motor already in the first device as the acoustic signal source, eliminating the need for a dedicated acoustic transmitter (such as a speaker or ultrasonic module), it effectively reduces reliance on external hardware devices, lowering the overall hardware complexity and cost of the system. In addition, since the first motor itself is the original standard configuration of the first device, its stability and reliability have been fully verified, its position is relatively fixed, its environmental adaptability is strong, and it is not easily damaged by external environmental influences. It avoids the risk of independent sound wave emitting devices in the existing technology being easily damaged in the external environment, thereby improving the reliability of the interaction.

[0102] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0103] With the rapid development of the Internet, electronic payment has become an important method of modern financial transactions. The key to this payment method lies in how to accurately verify personal identity. The basic methods of personal identity verification can be divided into three categories:

[0104] First, identity authentication based on private information. This authentication method relies on information held by the consumer, such as ID number, name, password, etc. Its advantage is that it is easy to implement, but its disadvantage is that information can be easily stolen, posing a security risk.

[0105] Second, identity authentication is based on items held by the user, such as bank cards, loan certificates, credit cards, USB shields, etc. The advantage of this method is high reliability, but there is a risk of item loss or theft.

[0106] Third, biometric-based identity authentication uses unique biometric features (such as palm print, face, iris, voiceprint, etc.) to verify identity. This method has the advantage of strong anti-counterfeiting, is difficult to steal or copy, and has high security.

[0107] Among them, the voiceprint feature is a voice spectrum realized through specific coding rules. Therefore, the voiceprint characteristics can carry identity information. Compared with traditional passwords, ID numbers and other information, voiceprint authentication is fast, stable, anti-counterfeiting and easy to carry.

[0108] Electronic payments include mobile payments, which can be accomplished by sending transaction instructions to banks or financial institutions via the internet via smart devices such as mobile phones, smartwatches, and AR glasses to complete fund transfers. This method offers the advantage of avoiding the risk of counterfeit currency and the hassle of manual change. Currently, mainstream mobile payment methods can be categorized by their information transmission method into near-field payment technologies: infrared, Bluetooth, acoustic wave, NFC, and QR code. Infrared payment technology has high device requirements, requiring specialized infrared transmitters and receivers. Bluetooth payment allows for near-field data exchange via Bluetooth devices, but requires Bluetooth protocol support. Transmission stability is affected by device compatibility, posing security risks. Acoustic wave payment relies on sound frequencies to encode and transmit payment information, enabling short-range payment. Acoustic wave payment does not rely on cellular network data, offers low latency, eliminates contactless payment, and is highly convenient, making it suitable for charging station payments, parking fees, toll booth payments, and vehicle maintenance. NFC payment utilizes NFC chips for short-range payment interactions. This payment method is limited by the compatibility of payment terminal devices, and the transaction distance is usually short (generally within 10 cm). QR code payment, such as mainstream payment methods such as WeChat Pay and Alipay, completes payment by scanning the QR code. This payment method relies on the phone camera and may fail if the QR code is damaged or defaced.

[0109] Figure 1 This is a functional block diagram of the prior art QR code acoustic wave payment device and its payment system, such as Figure 1 As shown, this payment system uses QR code scanning to process transaction requests between embedded devices such as mobile phones, watches, and glasses. When a transaction occurs, the user opens the payment QR code on the terminal device. The QR code acoustic wave payment device encodes the QR code information into a specific acoustic signal and emits the signal through a speaker. The payment system's settlement platform receives the acoustic signal through a microphone and interprets the QR code information. It then verifies the transaction information and completes the payment deduction process. Once the payment is completed, the QR code acoustic wave payment device returns the transaction results to the user terminal and uploads the transaction data to the payment system's settlement platform to complete the entire transaction process.

[0110] like Figure 1 As shown, the QR code acoustic wave payment device includes a power supply module, a microphone, a speaker, a power amplifier module, a processor module, a QR code module and a human body monitoring module.

[0111] However, existing QR code-based acoustic wave payment devices have significant shortcomings when applied to electric vehicle scenarios. These payment devices are relatively independent of the electric vehicle system, resulting in low integration and requiring the deployment of multiple additional hardware modules, significantly increasing the complexity and cost of the vehicle's equipment. Furthermore, since these external devices are easily exposed to environmental factors such as dust, moisture, and vibration, they are susceptible to damage, leading to increased maintenance costs. Furthermore, this method relies on a dedicated app (application) and QR code generation mechanism, making it impossible to complete the payment process independently of the QR code. Furthermore, it requires a constant internet connection, making payment transactions difficult in areas with poor signal strength or no cellular network coverage. Furthermore, this method requires the participation of an additional mobile device (such as a mobile phone or POS terminal) in the transaction process, preventing the full autonomous execution of the transaction process. Furthermore, this delivery method's overly simplistic authentication method for the transaction target presents security risks.

[0112] In general, in the related technologies, electronic interactive devices based on sound waves rely on independent sound wave emitting devices. Such electronic interactive devices are separated from the existing devices of electric vehicles and require additional equipment such as ultrasonic generators and speakers. This separate architecture leads to low device integration. Not only does it require the deployment of multiple hardware modules on the vehicle body, but it also brings greater system design complexity due to factors such as space, power supply, and environmental interference. At the same time, since these devices are often exposed to the surface of the vehicle, they are extremely susceptible to harsh external environments such as dust, water vapor, and vibration, causing device performance to degrade or even be damaged, further affecting the stability and interactive reliability of the overall system. In addition, the reuse rate of these devices is low and they are only used for sound wave communication. They fail to effectively utilize the existing actuator resources of electric vehicles, increasing the cost and maintenance complexity of the entire vehicle.

[0113] To address the above issues, embodiments of the present invention provide an interaction method that can be used with a first device, such as a vehicle, having a first controller and a first motor. This interaction method enables acoustic interaction directly using the motor, eliminating the need for additional acoustic wave emitting devices. This reduces the need for additional hardware, lowers device costs, and avoids the risk of damage to the additional hardware, thereby improving interaction reliability.

[0114] Reference below Figure 2-Figure 9 An interaction method according to an embodiment of the present invention is described.

[0115] Figure 2 is a flow chart of an interactive method according to an embodiment of the present invention. Figure 2 As shown, the interaction method of the embodiment of the present invention at least includes steps S1-S2.

[0116] S1: The first controller obtains an interaction request.

[0117] In some embodiments, the interaction request can be triggered by the local internal logic of the first device or by a signal sent by an external system. Specifically, the interaction request can be initiated by the first device itself. For example, when the vehicle detects that the charging gun is inserted and the charging pile is successfully locked, the local sensor of the first device detects the state change and then transmits the interaction request to the first controller via the vehicle bus or other internal communication bus. It can also be initiated by an external device or system. For example, a third-party payment platform sends an interaction request to the first device by calling an API interface during the transaction initiation phase. The interaction request is transmitted to the first controller for processing via a wireless communication module (such as Wi-Fi, cellular communication, Bluetooth, etc.). In addition, the interaction request can also come from user operations. For example, after the user clicks the payment button or confirms the interaction instruction in the vehicle system, the vehicle system generates an interaction request and transmits it to the first controller. After receiving the interaction request, the first controller immediately enters the subsequent sound wave signal sending process.

[0118] S2. The first controller controls the first motor to emit a first sound wave signal. The first sound wave signal includes interaction information, and the interaction information is obtained according to the interaction request.

[0119] In some embodiments, the first controller can be a motor controller, which controls the first motor to rotate at high speed or vibrate in a specific manner, so that the first motor itself emits a first sound wave signal with a specified frequency and specified loudness. The sound wave signal carries interactive information, thereby realizing the function of transmitting information through sound waves.

[0120] In some embodiments, after the first controller obtains the interaction request, the first device can obtain the interaction information required for the transaction activity, including but not limited to: payment amount, product number, serial number, buyer token, timestamp and other necessary data related to the transaction process.

[0121] In some embodiments, the interactive methods of the present invention utilize the powertrains inherent in electric vehicles, reusing motors to generate sound waves of a specified frequency and amplitude. Because no additional hardware is required, they can be deployed on a large scale via Over-The-Air (OTA) technology. This allows for remote push of software updates or feature upgrades via wireless networks, eliminating the need for manual hardware replacement in vehicles and making implementation simple.

[0122] In some embodiments, the interactive method of the embodiments of the present invention does not rely on QR codes, does not rely on the assistance of additional mobile devices, can be independent of third-party devices, and does not rely on cellular networks, Bluetooth, WiFi, etc. for short-distance communication. It can be applied to electric vehicle charging stations to achieve charging protocol matching, charging request sending, unattended charging, automatic settlement, and can also be used for automatic payment in parking lots.

[0123] In some embodiments, since the loudness and frequency of the sound wave signal generated by the motor are adjustable, it has the effect of confidential transmission in a physical sense, and its transmission content is not easily monitored or stolen.

[0124] According to the interaction method of an embodiment of the present invention, after receiving an interaction request, the first controller controls the operation of the first motor, causing it to begin vibrating and thereby emitting a first sound wave signal of a specific frequency and specific loudness. This signal carries the interaction information, thereby enabling acoustic transmission of information. Because this method directly reuses the first motor already in the first device as the source of the sound wave signal, eliminating the need for an additional dedicated sound wave transmitter (such as a speaker or ultrasonic module), it can effectively reduce reliance on external hardware devices, lowering the overall hardware complexity and cost of the system. Furthermore, since the first motor itself is a standard feature of the first device, its stability and reliability have been fully verified. Its relatively fixed position and strong environmental adaptability make it less susceptible to damage due to external environmental influences. This avoids the risk of damage to independent sound wave transmitters in the prior art, thereby improving the reliability of the interaction.

[0125] In some embodiments, the first controller controls the operation of the first motor by sending a control signal to the first motor, where the control signal includes transaction information, including but not limited to: payment amount, product number, serial number, buyer token, timestamp, and other necessary data related to the transaction process.

[0126] In some embodiments, the control signal is a signal encoded using a preset encoding rule.

[0127] Preset encoding rules may include, but are not limited to, frequency shift keying (FSK), amplitude shift keying (ASK), and phase shift keying (PSK). Furthermore, the encoder's encoding style may utilize character sets such as the American Standard Code for Information Interchange (ASCII) or the Chinese Internal Code Extension (GBK). The encoder can assemble the interactive information to be transmitted into a pre-formatted message that complies with the communication protocol requirements. This message may include a 1-byte flag bit, a 2-byte length bit, a 1-byte parity bit, and several bytes of data bits to ensure the integrity and accuracy of the information parsing process.

[0128] Specifically, the first controller can encode the interactive information using the preset encoding rules to obtain an acoustic wave signal whose acoustic wave characteristics correspond to the interactive information. The first controller then further generates an inverter control signal based on the generated acoustic wave signal, where the inverter control signal can be a PWM (Pulse Width Modulation) signal used to control the first motor to emit a corresponding acoustic wave signal. The first controller sends a PWM signal to the inverter, and the inverter controls the current amplitude and frequency in the stator coil of the first motor according to the duty cycle of the PWM signal, thereby causing the first motor to generate mechanical vibrations with a specific frequency and loudness. As a result, the first motor can emit a first acoustic wave signal containing the interactive information, achieving the purpose of transmitting the interactive information through acoustic waves.

[0129] In some embodiments, before the first controller controls the first motor to emit the first sound wave signal, the interaction method further includes: the first controller obtains a user confirmation instruction for the interaction information.

[0130] In some embodiments, after receiving the interaction request, the first device does not immediately perform the sound wave emission action, but requires the user to actively confirm the operation first, thereby improving the control authority during the interaction process and the security of the transaction.

[0131] Specifically, the first controller can display interactive information (such as payment method, payment amount, product name, transaction serial number, payment channel, payment status, etc.) to the user. After confirming that the interactive information is correct, the user generates and sends a confirmation instruction. After receiving the user's confirmation instruction, the first controller can combine and encode the interactive information and the confirmation instruction, modulate the combined data according to preset encoding rules, and generate a corresponding acoustic wave signal. Subsequently, the first controller generates a PWM signal based on the acoustic wave signal to control the operation of the inverter to drive the first motor, thereby causing the first motor to emit a first acoustic wave signal containing the interactive information and the confirmation instruction, thereby achieving secure information transmission.

[0132] In some embodiments, the method for generating the user confirmation instruction may include, but is not limited to: physical button confirmation, touch screen click confirmation, voice command confirmation, biometric confirmation (e.g., fingerprint recognition, facial recognition), etc. Different confirmation methods can be flexibly selected according to specific application scenarios to meet different security levels and interaction convenience requirements.

[0133] In some embodiments, the interaction method further includes: the first controller presenting confirmation information including the interaction information to the user through the terminal device for user confirmation.

[0134] The terminal device may include, but is not limited to, an in-vehicle central control screen, a smart instrument panel, a head-up display (HUD), etc. After the user verifies that the displayed transaction details are correct, they can click the "Confirm" button on the terminal device's interface. In response to the user's confirmation instruction, the first controller combines and encodes the user confirmation instruction with the target interaction information and modulates it into a first sound wave signal. If the user clicks the "Cancel" button on the terminal device interface, the generation of the first sound wave signal is stopped, and a "Transaction Cancelled" or similar prompt message pops up on the terminal device to prompt the user that the current operation has been terminated, thereby ensuring the security and controllability of the transaction process.

[0135] In some embodiments, the terminal device is a terminal device of the first device or a mobile terminal connected to the first controller. The terminal device of the first device may refer to a display and interaction device integrated into the first device (e.g., a vehicle), such as an in-vehicle central control screen, a smart instrument panel, or a head-up display (HUD). In this case, the first controller within the first device may directly invoke the terminal interface built into the device to display interaction information for user confirmation.

[0136] In some embodiments, the mobile terminal connected to the first controller may be an external device connected to the first controller wirelessly or wired, such as a mobile phone, tablet computer, smartwatch, or an in-vehicle passenger entertainment tablet. In this case, the first controller may send the interaction information to the mobile terminal via, for example, Bluetooth, Wi-Fi, NFC (Near Field Communication), or a wired interface (such as USB, Universal Serial Bus), which then displays the interaction information to the user and receives confirmation instructions from the user.

[0137] In some embodiments, the interaction request may be that the first device actively monitors the sound wave interaction request or receives the sound wave interaction request through an application programming interface.

[0138] Among them, the first device actively monitoring the sound wave interaction request may refer to the first device periodically or continuously actively monitoring the external physical state, network connection status, user operation behavior and other triggering conditions through its built-in control logic to determine whether there is a scenario where sound wave interaction needs to be performed. For example, when it is detected that a vehicle is plugged into a charging gun, the first device can automatically generate a sound wave interaction request related to the charging fee. Receiving a sound wave interaction request through an application programming interface may refer to the first device being called by a third-party application through an API (Application Programming Interface), sending a target interaction request to it, and the first device executing the subsequent sound wave interaction process after receiving the request.

[0139] In some embodiments, the interaction information includes transaction information. Specifically, when the interaction information includes transaction information, the first device transmits this transaction information to the second device via a first acoustic signal. This provides basic data for subsequent payment verification, authentication, settlement, and other operations. Because transaction information often contains sensitive data (such as account number and amount), encryption or other methods may be required to ensure information security during transmission. This can be combined with an authentication mechanism to ensure the security and legitimacy of the information transmission process.

[0140] In some embodiments, the transaction information includes at least one of the following: payment method, payment amount, product name, transaction serial number, payment channel, and payment status. In acoustic interaction, the transmission of transaction information facilitates transaction automation, ensuring that all transaction details are accurately transmitted to the receiving device and can be verified and processed during transaction settlement.

[0141] In some embodiments, the first device further includes a first sound wave receiving module, and the interaction method further includes: the first sound wave receiving module receives a second sound wave signal including first feedback information, and the first feedback information includes a transaction result.

[0142] Receiving the second sound wave signal containing the first feedback information can be achieved by a first sound wave receiving device in the first device, such as a built-in microphone, an external microphone, or a sound wave sensing device of a specific frequency. The sound wave receiving device can collect the second sound wave signal containing the first feedback information and convert the collected analog sound wave signal into a digital signal for subsequent processing.

[0143] In some embodiments, the decoding module built into the first device can demodulate and restore the received second sound wave signal based on a preset modulation and demodulation protocol, thereby extracting the effective first feedback information therefrom.

[0144] In some embodiments, the transaction result is used to indicate whether the corresponding business interaction is successfully completed, for example, whether the payment is completed, whether the order is generated, or whether the recharge is successful.

[0145] In some embodiments, the first device may graphically present transaction results to the user through its terminal device (such as a vehicle's central control screen, instrument panel, or head-up display) to enhance interaction transparency and user experience. For example, a text prompt such as "Payment Successful" or "Payment Failed" may pop up on the display screen, or real-time feedback may be provided through voice announcements.

[0146] In some embodiments, the interaction method further includes: the first controller controlling the first motor to emit a third sound wave signal, where the third sound wave signal includes device information of the first device. The device information of the first device may include, but is not limited to, device ID (identity), device model, manufacturer information, device configuration, etc.

[0147] In some embodiments, if the first device is a vehicle, the device information may include but is not limited to: frame number, motor number, license plate information, vehicle model information, manufacturer information, etc.

[0148] In some embodiments, the device information carried by the third acoustic signal can provide an important data foundation for subsequent authentication and verification. For example, it may be necessary to verify the legitimacy of the first device or to authorize the first device. The included device information can be used as part of the identity verification process to confirm the legitimacy of the first device by comparing it with the information in the device database. This process can enhance system security and ensure that only authorized devices can proceed with subsequent operations.

[0149] In some embodiments, the first device also includes a first sound wave receiving module, and the interaction method also includes: the first sound wave receiving module receives a fourth sound wave signal containing second feedback information, the second feedback information includes an authentication result, and the authentication result is obtained by authentication based on the authentication information generated by the device information.

[0150] The second feedback information includes the authentication result. The authentication result can refer to a determination of the device's legitimacy or identity. This result can be a "success" or "failure" flag, indicating whether the device has passed security verification. For example, if the device information matches a record in the database, "authentication successful" is returned; otherwise, "authentication failed" is returned.

[0151] In some embodiments, the fourth acoustic wave signal carries the authentication result and is received by the first acoustic wave receiving module of the first device. The fourth acoustic wave signal is used to return the authentication result from the second device to the first device, notifying the device of the result of the authentication process. For example, in a vehicle scenario, after verification, if the device information such as the vehicle frame number successfully matches, the fourth acoustic wave signal will return a "successful authentication" message, indicating that the device can continue to perform operations.

[0152] In some embodiments, the authentication result can be graphically presented to the user via a terminal device of the first device (such as an in-vehicle central control screen, instrument panel, HUD, etc.), thereby improving interaction transparency and user experience. For example, a text prompt such as "Authentication successful" or "Authentication failed, please try again" can be displayed on the screen, or feedback can be provided through voice broadcast or other means.

[0153] In some embodiments, the first device may be a vehicle. The vehicle may serve as the active or passive party of the acoustic wave interaction and may exchange information with external devices such as charging stations, parking gates, gas station terminals, access control systems, and unmanned stores.

[0154] The second embodiment of the present invention further proposes an interaction method, which is used for a second device. The second device includes a second controller and a second sound wave receiving module, wherein the second sound wave receiving module can be any device that can perceive sound wave signals, such as a microphone.

[0155] Figure 3 is a flow chart of an interactive method according to another embodiment of the present invention. Figure 3 As shown, the interaction method of the embodiment of the present invention at least includes steps S10-S11.

[0156] S10, a second sound wave receiving module receives a first sound wave signal, where the first sound wave signal is emitted by a first motor of a first device and contains interaction information.

[0157] Specifically, after the sound wave interaction is initiated, the second sound wave receiving module in the second device continuously monitors the sound wave signals within a predetermined frequency band (e.g., 1kHz–8kHz) until it successfully receives the first sound wave signal containing the interaction information. The received analog sound wave signal is then bandpass filtered to remove ambient noise and signals outside the target frequency band. The analog signal is then converted to digital at a set sampling rate (e.g., 16kHz or 32kHz) to obtain a digitized sound wave signal sequence.

[0158] S11: The second controller obtains interaction information according to the first sound wave signal.

[0159] Specifically, the second controller may extract the interactive information in the first sound wave signal through decoding technology, and perform corresponding operations according to the information.

[0160] According to the interaction method of an embodiment of the present invention, a second device, through its own second sound wave receiving module, can receive a first sound wave signal generated by the operation of the first motor of the first device. This signal contains interaction information. Specifically, after receiving an interaction request, the first controller controls the operation of the first motor, causing it to vibrate, thereby emitting a first sound wave signal of a specific frequency and loudness. This signal carries the interaction information, thereby enabling acoustic transmission of information. Because this method directly reuses the first motor already in the first device as the source of the sound wave signal, eliminating the need for a dedicated sound wave transmitter (such as a speaker or ultrasonic module), it effectively reduces reliance on external hardware devices, lowering the overall hardware complexity and cost of the system. Furthermore, since the first motor itself is a standard feature of the first device, its stability and reliability have been fully verified. Its relatively fixed position and strong environmental adaptability make it less susceptible to damage due to external environmental influences. This avoids the risk of damage to independent sound wave transmitters in the existing technology, thereby improving the reliability of the interaction.

[0161] In some embodiments, the interaction information is obtained by the second controller decoding the first sound wave signal according to a preset decoding rule.

[0162] Specifically, after receiving the digital sound wave signal, the second controller in the second device may decode the signal according to a preset decoding rule. The preset decoding rule may adopt a standard character encoding method, such as American Standard Code for Information Interchange (ASCII), GBK (Extended Standard for Chinese Character Encoding), or Unicode.

[0163] Furthermore, during the decoding process, the second controller first performs an integrity check on the acoustic signal packet. Common check methods include CRC, parity, or hashing. Once the integrity check passes, the second controller parses the message structure according to the frame format, identifying the flag bit, length field, data field, and check field within the message. The second device then converts the data field according to the specified character encoding method to recover the original interaction information.

[0164] In some embodiments, the second device further includes a sound wave transmitting module, and the interaction method further includes: the second controller controls the sound wave transmitting module to transmit a fifth sound wave signal, where the fifth sound wave signal includes confirmation information corresponding to the interaction information.

[0165] In some embodiments, the sound wave transmitting module can be an ultrasonic sensor, a buzzer, a speaker, or other devices.

[0166] In some embodiments, the fifth acoustic wave signal includes "confirmation information" related to the interaction information, that is, confirmation or response to the interaction information. This information can be used to ensure effective information exchange between the first device and the second device, or to confirm certain parameters of the interaction process.

[0167] Specifically, after the second device completes the reception and parsing of the interactive information, in order to ensure that the transaction behavior is initiated with the authorization of a legitimate user and to avoid erroneous operations or unauthorized automatic transactions, it will generate a confirmation information corresponding to the interactive information, and encode the confirmation information and the interactive information to generate a corresponding fifth sound wave signal, which is sent to the first device. After the first device receives the fifth sound wave signal, it presents the confirmation information containing the corresponding interactive information to the user for confirmation through the terminal device. When the user verifies that the transaction details are correct, he or she can click the "Confirm" button on the interface of the interactive device. The first device then combines the user confirmation instruction with the interactive information, encodes it, and modulates it into a first sound wave signal for transmission. The second device will obtain the first sound wave signal containing the confirmation instruction as the final authorization signal for executing the transaction or continuing the subsequent process. This method forms a two-way confirmation interaction mechanism based on sound waves, which can effectively reduce the probability of erroneous transactions and improve the controllability of the interaction and user trust.

[0168] In some embodiments, the second device further includes a first communication module, and the interaction method further includes: the second controller controls the first communication module to send interaction information.

[0169] Specifically, when the second device receives the first sound wave signal containing the user confirmation instruction sent by the first device, the second controller in the second device can decode the first sound wave signal based on a preset decoding rule to obtain the interaction information. The second controller then controls the first communication module to upload the interaction information to the server.

[0170] In some embodiments, the first communication module may be a Wi-Fi module, a cellular communication module (such as a 4G or 5G module), or a Bluetooth module, etc., suitable for data transmission requirements in different application environments.

[0171] In some embodiments, the interaction information includes transaction information. Specifically, a second acoustic wave receiving module in the second device may receive a first acoustic wave signal emitted by the first device, and a second controller may decode the first acoustic wave signal based on a preset decoding rule to obtain the interaction information. The second controller may further extract transaction information related to the transaction from the interaction information.

[0172] In some embodiments, the transaction information includes at least one of the following: payment method, payment amount, product name, transaction serial number, payment channel, and payment status.

[0173] In some embodiments, the second device further includes an acoustic wave transmission module, and the interaction method further includes: the first communication module receiving a transaction result corresponding to the transaction information; and the second controller controlling the acoustic wave transmission module to transmit a second acoustic wave signal including the first feedback information, where the first feedback information includes the transaction result.

[0174] Specifically, after the transaction settlement is completed, the transaction settlement platform will generate a corresponding transaction result based on the sent transaction information and transmit the transaction result back to the second device. The first communication module in the second device is responsible for receiving the transaction result and providing it to the second controller. The second controller encodes the transaction result into first feedback information according to the preset coding rules, and sends the first feedback information to the first device in the form of a sound wave signal (i.e., a second sound wave signal) by controlling the sound wave transmitting module. The first sound wave receiving module in the first device receives the second sound wave signal containing the first feedback information, and converts the collected analog sound wave signal into a digital signal for subsequent processing by the first controller. The first controller decodes the digital signal based on the preset decoding rules, parses the first feedback information contained therein, and thereby extracts the transaction result, thereby confirming the completion status of the transaction.

[0175] In some embodiments, the interaction method further includes: the second controller controlling the first communication module to transmit authentication information of the first device, where the authentication information is generated based on the device information of the first device. Methods for generating the authentication information may include: directly using the device information as the authentication information; encrypting the device information (e.g., using symmetric encryption, asymmetric encryption, hash encryption, etc.) to generate the authentication information; or generating a one-time authentication token based on the device information combined with dynamic elements such as a current timestamp and a random number.

[0176] In some embodiments, the interaction method further includes: the second sound wave receiving module receives a third sound wave signal, the third sound wave signal is emitted by the first motor of the first device, and the third sound wave signal contains device information of the first device.

[0177] Specifically, when the first device interacts with the second device, to ensure the security of the interaction and the legitimacy of the device identity, the first controller can generate authentication information based on the device information of the first device. Then, the first controller encodes the authentication information according to a preset encoding rule to generate a control signal. The first controller controls the operation of the first motor by sending the control signal to the first motor to generate a third sound wave signal containing the device information of the first device.

[0178] Furthermore, after the second device receives a third acoustic signal sent by the first device containing the first device's authentication information, the second controller in the second device can decode the third acoustic signal based on preset decoding rules to extract the first device's authentication information. The second controller then uploads the authentication information (such as the vehicle frame number, motor number, license plate information, vehicle model information, etc.) to the server via the first communication module. The server verifies the legitimacy of the first device based on the authentication information and proceeds with subsequent interactions or transactions.

[0179] In some embodiments, the interaction method further includes: the second controller receiving authentication information of the first device, the authentication information is generated based on device information of the first device, and the device information of the first device is obtained based on image information of the first device.

[0180] The image information of the first device can be acquired using an image acquisition device (such as a camera or sensor). The image information may include the first device's appearance, identifiers (such as a license plate, barcode, or QR code), or other characteristic images related to the first device. The image information can be used to extract the device's unique identification information (such as the device model, serial number, and production date) using image recognition algorithms (such as machine vision and deep learning).

[0181] In some embodiments, the second device further includes an acoustic wave transmission module, and the interaction method further includes: a second controller receiving an authentication result, where the authentication result is obtained by authenticating the first device based on the authentication information; and the second controller controlling the acoustic wave transmission module to transmit a fourth acoustic wave signal including second feedback information, where the second feedback information includes the authentication result.

[0182] Specifically, the second controller controls the first communication module to send the authentication information of the first device to the server. The server will authenticate the first device based on the received authentication information, including verifying data integrity, verifying the legitimacy of the transaction, identifying the identity of the transaction user, etc., so as to prevent forgery or tampering of information. When the server completes the authentication process, the second controller receives the authentication result sent by the server. The authentication result may include information such as "authentication successful" or "authentication failed". The second controller can encode the authentication result and generate a second feedback message. The second feedback information not only includes the authentication result, but also includes more detailed information, such as the device status, the steps that can be continued after successful authentication, or a prompt that re-authentication is required.

[0183] Furthermore, the second controller controls the acoustic wave transmitting module to transmit a fourth acoustic wave signal containing the second feedback information to the first device. The first acoustic wave receiving module in the first device can receive the fourth acoustic wave signal and convert it into a digital signal for subsequent processing. The first controller then decodes the fourth acoustic wave signal according to a preset decoding rule and extracts the second feedback information. Based on the decoded feedback information, the first device will be able to obtain the authentication result and perform corresponding subsequent operations based on different feedback results, such as continuing the interaction, re-authenticating, or terminating the interaction.

[0184] The third embodiment of the present invention further proposes an interaction method, which is used for a server.

[0185] Figure 4 is a flow chart of an interactive method according to another embodiment of the present invention. Figure 4 As shown, the interaction method of the embodiment of the present invention at least includes steps S20-S22.

[0186] S20 , receiving interaction information, where the interaction information is obtained based on a first sound wave signal emitted by a first motor of a first device.

[0187] Specifically, the first controller controls the first motor to rotate at high speed or vibrate in a specific manner, so that the first motor itself emits a first sound wave signal with a specified frequency and specified loudness. The sound wave signal carries interactive information, thereby realizing the function of transmitting information through sound waves.

[0188] Furthermore, the second sound wave receiving module in the second device continuously monitors sound wave signals within a predetermined frequency band (e.g., 1kHz–8kHz) until it successfully receives the first sound wave signal containing the interactive information. The received analog sound wave signal is then bandpass filtered to remove ambient noise and non-target frequency band signals. The analog signal is then analog-to-digital converted at a set sampling rate (e.g., 16kHz or 32kHz) to obtain a digitized sound wave signal sequence. The second controller can extract the interactive information from the first sound wave signal through decoding technology and perform corresponding operations based on this information.

[0189] Furthermore, the second device may send the interaction information to the server through the first communication module, and the server may receive the interaction information through wireless communication.

[0190] S21, obtaining interactive feedback information, where the interactive feedback information is obtained by interactive processing based on the interactive information.

[0191] In some embodiments, the interactive feedback information may be digital information or encoded data with a specific format or protocol to ensure that it can be understood by the recipient (eg, the second device).

[0192] S22: Send interactive feedback information.

[0193] Specifically, after processing the interaction information, the server may send the generated interaction feedback information to the target device (eg, the second device, etc.) through a network or a communication interface.

[0194] According to an interaction method according to an embodiment of the present invention, a server can receive and process interaction information to obtain interaction feedback information. The interaction information is obtained based on a first acoustic wave signal emitted by a first motor of a first device. Specifically, after receiving an interaction request, the first controller controls the first motor to vibrate, thereby emitting a first acoustic wave signal of a specific frequency and loudness. This signal carries the interaction information, thereby enabling acoustic transmission of the information. Because this method directly reuses the first motor already in the first device as the source of the acoustic wave signal, eliminating the need for a dedicated acoustic wave transmitter (such as a speaker or ultrasonic module), it effectively reduces reliance on external hardware devices, lowering the overall hardware complexity and cost of the system. Furthermore, since the first motor itself is a standard feature of the first device, its stability and reliability have been fully verified. Its relatively fixed position and strong environmental adaptability make it less susceptible to damage due to external environmental influences. This avoids the risk of damage to independent acoustic wave transmitters in the prior art, thereby improving the reliability of the interaction.

[0195] In some embodiments, the interaction information includes transaction information. Specifically, the server may receive the transaction information sent from the second device and, based on the transaction information, invoke a transaction settlement platform. The transaction settlement platform may complete settlement operations such as transaction deductions based on the transaction information and generate a transaction result (e.g., transaction success, payment failure, etc.). After completing the settlement operation, the transaction settlement platform may feed the transaction result back to the server.

[0196] In some embodiments, the transaction information includes at least one of the following: payment method, payment amount, product name, transaction serial number, payment channel, and payment status.

[0197] In some embodiments, a vehicle is pre-linked to a bank account or third-party payment account when it is purchased or first connected to the platform. Once linked, the vehicle's unique identifier (such as the vehicle frame number or motor number) is automatically linked to the payment account. During subsequent transactions, the system can quickly identify the user based on this unique identifier and automatically deduct payments, eliminating the need for the user to repeatedly enter their account number or authorize payment each time.

[0198] Therefore, because the motor or vehicle code is inherently unique, it can serve as a natural basis for identity authentication in certain scenarios, significantly simplifying the traditional registration and authentication process. Compared to traditional methods that require account registration, bank card binding, or manual authorization, the present invention uses acoustic interaction technology to complete device identification, identity verification, and payment settlement, greatly improving the convenience of interaction and user experience. This acoustic interaction technology can also be extended to near-field transmission of arbitrary encoded information.

[0199] In some embodiments, the interactive feedback information includes the transaction results of the corresponding transaction information. For example: transaction success, transaction failure, etc. Specifically, the server can send the transaction results to the second device, and the first communication module in the second device is responsible for receiving the transaction results and providing them to the second controller. The second controller encodes the transaction results into first feedback information according to the preset coding rules, and sends the first feedback information to the first device in the form of a sound wave signal (i.e., a second sound wave signal) by controlling the sound wave transmitting module. The first sound wave receiving module in the first device receives the second sound wave signal containing the first feedback information, and converts the collected analog sound wave signal into a digital signal for subsequent processing by the first controller. The first controller decodes the digital signal based on the preset decoding rules, parses out the first feedback information contained therein, and thereby extracts the transaction results, thereby confirming the completion status of the transaction.

[0200] In some embodiments, before obtaining interactive feedback information, the interactive method further includes: receiving authentication information of the first device; obtaining an authentication result, where the authentication result is obtained by authenticating the first device based on the authentication information; and sending the authentication result. Specifically, the server can receive authentication information of the first device sent by the first communication module in the second device. The server can authenticate the first device based on the received authentication information, including verifying data integrity, verifying the legitimacy of the transaction, identifying the identity of the transaction user, etc., thereby preventing forgery or tampering of information. When the server completes the authentication process, the server can send the authentication result to the first communication module in the second device. After receiving the authentication result, the first communication module transmits the authentication result to the second controller. The second controller then encodes the authentication result and generates second feedback information containing the result. The second controller controls the sound wave transmission module to transmit a fourth sound wave signal containing the second feedback information, which is transmitted to the first device, thereby feeding back the authentication result to the first device.

[0201] In this way, the first device can receive the authentication result (e.g., "authentication successful" or "authentication failed") via an acoustic signal and perform corresponding operations based on the authentication result. This effectively ensures security and identity verification during the interaction process, preventing the involvement of unauthorized devices or users.

[0202] In some embodiments, interaction feedback information is obtained through interaction processing based on interaction information after the first device has been authenticated. This means that subsequent interaction can only proceed after the authentication information has been effectively verified and the identity of the first device has been confirmed. If authentication fails, the interaction will be interrupted or re-authentication will be requested to ensure the security and legitimacy of the transaction.

[0203] The fourth embodiment of the present invention further proposes an interaction method, which is used for a third device.

[0204] Figure 5 is a flow chart of an interactive method according to another embodiment of the present invention. Figure 5 As shown, the interaction method of the embodiment of the present invention at least includes steps S30-S32.

[0205] S30: Obtain device information of the first device according to the image information of the first device, wherein the first device is a device for sending a first sound wave signal of interaction information.

[0206] In some embodiments, the third device may capture image information of the first device through an image acquisition module and analyze the image using an image recognition algorithm to extract identifiable features of the first device to further obtain device information of the first device. The device information of the first device may include, but is not limited to, device ID, device model, manufacturer information, device configuration, etc.

[0207] S31, obtaining authentication information, where the authentication information is generated based on device information.

[0208] Specifically, if the first device is a vehicle, the device information may include, but is not limited to, vehicle frame number, motor number, license plate, vehicle model, and manufacturer information. The third device can use the identified vehicle information to further retrieve or match the corresponding vehicle registration information, such as the owner's payment information and associated payment channels. Based on this vehicle information, an identification code uniquely corresponding to the first device can be generated. The vehicle information, payment information, associated payment channels, and identification code are then combined to generate authentication information for the first device.

[0209] S32, sending authentication information.

[0210] Specifically, the third device may send the authentication information to the second device via an acoustic signal, or may send the authentication information to the second device via wireless communication, for subsequent authentication in the server.

[0211] According to the interaction method of an embodiment of the present invention, a third device can extract device information containing the first device's identification or attributes by collecting and identifying image information from the first device. This device then generates and transmits authentication information to the second device. This authentication method effectively prevents interception, replay, or tampering attacks, thereby improving transaction security. Furthermore, the acoustic signal containing the interaction information is generated by the first motor in the first device. Specifically, after receiving the interaction request, the first controller controls the first motor to vibrate, thereby emitting a first acoustic signal of a specific frequency and loudness. This signal carries the interaction information, thereby enabling acoustic transmission of information. Because this method directly reuses the first motor already in the first device as the acoustic signal source, eliminating the need for a dedicated acoustic transmitter (such as a speaker or ultrasonic module), it effectively reduces reliance on external hardware devices, lowering the overall hardware complexity and cost of the system. In addition, since the first motor itself is the original standard configuration of the first device, its stability and reliability have been fully verified, its position is relatively fixed, its environmental adaptability is strong, and it is not easily damaged by external environmental influences. It avoids the risk of independent sound wave emitting devices in the existing technology being easily damaged in the external environment, thereby improving the reliability of the interaction.

[0212] In some embodiments, the present invention combines authentication information with secondary composite authentication of transaction information, thereby improving transaction security and preventing the signal from being intercepted during the generation of the acoustic wave signal and suffering from replay attacks.

[0213] In some embodiments, the interaction method further includes: generating sound wave transmission and reception direction adjustment information based on the relative position of the first device and the second device, and sending the sound wave transmission and reception direction adjustment information to the second device, where the second device is a device that interacts with the first device through sound waves.

[0214] The relative position of the first and second devices can refer to the spatial relationship between the two devices, such as distance and angle. This information determines the transmission path and strength of the acoustic signal. The transmission efficiency and reliability of acoustic signals are affected by the location of the devices. For example, physical obstacles (such as walls or metal objects) or excessive distance between the devices may cause signal attenuation or distortion. Therefore, a third device can monitor the position of the first and second devices in real time and, based on this information, generate acoustic transmission and reception direction adjustment information to optimize signal transmission.

[0215] In some embodiments, the sound wave transmission and reception direction adjustment information may include the sound wave transmission angle, sound wave reception angle, and signal strength adjustment. The third device can send the sound wave transmission and reception direction adjustment information to the second device via wireless communication (such as Wi-Fi, Bluetooth, etc.) or sound waves. Upon receiving the sound wave transmission and reception direction adjustment information, the second device adjusts the direction of its sound wave receiver or transmitter accordingly. This approach ensures interference-free transmission of sound wave signals and maximizes signal reception quality.

[0216] Based on the interaction method described in the above embodiment, Figure 6 Describes the logical process of sound wave interaction between the first device and the second device.

[0217] Figure 6 FIG. 1 is a logic diagram of a first device and a second device performing sound wave interaction according to an embodiment of the present invention. Figure 6As shown, assuming the first device is a vehicle and the second device is a charging station, when the vehicle is detected to be plugged into a charging station, the vehicle's onboard host can actively monitor for an acoustic interaction request. This acoustic interaction request can include the charging station's device ID and the data to be transmitted, i.e., the interaction information. The onboard host can transmit the interaction information to a first controller. The first controller encodes the interaction information to generate an acoustic signal whose acoustic characteristics match the interaction information. The controller then generates a corresponding pulse-width modulation (PWM) signal based on the acoustic signal. The PWM signal is transmitted to an inverter. The inverter controls the current level and frequency in the stator coil of the first motor based on the duty cycle of the PWM signal, causing the first motor to generate mechanical vibrations of a specific frequency and loudness, thereby emitting a first acoustic signal containing the interaction information, thus achieving acoustic information transmission. The charging station can capture this acoustic signal through its built-in acoustic detection module (e.g., a microphone) and parse it to extract the interaction information, thereby enabling data exchange between the vehicle and the charging station.

[0218] Based on the interaction method described in the above embodiment, Figure 7 The process of the sound wave payment method is described, in which a first sound wave signal sent by a first device is decoded in a second device.

[0219] Figure 7 is a flow chart of a sound wave payment method according to an embodiment of the present invention. Figure 7 As shown, the process of the acoustic wave payment method includes at least steps S100-S106.

[0220] S100: A first device actively monitors a sound wave interaction request or receives a sound wave interaction request through an application programming interface.

[0221] S101: A first controller obtains an interaction request and acquires interaction information required for a transaction activity.

[0222] S102: The first controller transmits the interaction information to the terminal device, and presents confirmation information including the interaction information to the user for confirmation via the terminal device.

[0223] S103: After the user confirms, the authentication is passed, and the system organizes the interaction information to be sent and transmits it to the first controller.

[0224] S104, the first controller encodes the interactive information to obtain a sound wave signal whose sound wave characteristics match the interactive information, generates an inverter control signal based on the sound wave signal, and drives the first motor to emit a first sound wave signal through the inverter based on the inverter control signal.

[0225] S105: The second device receives the first sound wave signal containing the interaction information and performs a decoding operation to obtain the interaction information, and sends the interaction information to the transaction settlement platform for settlement.

[0226] S106, the transaction settlement platform completes the settlement and the transaction is completed.

[0227] In some embodiments, if the first device is a vehicle and the second device is a charging station, when a program within the vehicle's host computer actively detects an acoustic interaction request, or when the charging station sends an acoustic interaction request to the vehicle via a pre-defined API, the vehicle's host computer will begin processing. Upon receiving the interaction request, the vehicle's host computer will extract interaction information related to the transaction. This interaction information includes, but is not limited to, key transaction information such as payment method, payment amount, product name, product number, transaction serial number, payment channel, payment status, and buyer token. A confirmation message containing the interaction information is then presented to the user for confirmation via a terminal device (such as an in-vehicle central control screen, instrument panel, or head-up display). When the user clicks "Confirm," authentication is successful, and the vehicle system compiles the interaction information to be sent and transmits it to the first controller. The first controller encodes the interaction information to obtain an acoustic signal whose acoustic wave characteristics match the interaction information. Based on the acoustic signal, it generates an inverter control signal. Based on the inverter control signal, the inverter drives the first motor to emit the first acoustic signal. The charging station receives the first acoustic signal containing the interaction information and decodes it to obtain the interaction information. This information is then transmitted to the transaction settlement platform for settlement. The transaction settlement platform executes the payment deduction based on the received interactive information and returns the transaction result (such as payment success or payment failure) to the charging station. The charging station then feeds the payment result back to the vehicle, completing the transaction.

[0228] Based on the interaction method described in the above embodiment, Figure 8 Describe the interaction logic between the first device, the second device and the server.

[0229] Figure 8 is a flow chart of the interaction logic between the first device, the second device and the server according to one embodiment of the present invention. Figure 8As shown, if the first device is a vehicle and the second device is a charging station, the vehicle host, multimedia device, or other display device with an operating system in the vehicle can initiate a transaction request containing key information such as the user's purchased items and payment amount. This means that the vehicle is the data source for the entire transaction process, responsible for collecting and transmitting relevant information, namely, interaction information. The interaction information is then sent to the first controller in the first device (the vehicle). The first controller encodes the interaction information to obtain an acoustic signal whose acoustic characteristics match the target interaction information. The controller then generates a corresponding pulse-width modulation (PWM) signal based on the acoustic signal. The PWM signal is transmitted to the inverter, which controls the current and frequency in the stator coil of the first motor according to the duty cycle of the PWM signal, causing the first motor to generate mechanical vibrations of a specific frequency and loudness, thereby emitting the first acoustic signal containing the interaction information.

[0230] Furthermore, the second device (charging station) can capture the first sound wave signal containing the interactive information through its built-in sound wave detection module (e.g., a microphone), and perform enhancement, filtering, and denoising on the first sound wave signal, thereby extracting the effective sound wave signal from the ambient noise, filtering out interference signals, and performing analog-to-digital conversion to generate a digitized sound wave signal sequence. The device used to process the first sound wave signal may include one or more general-purpose microprocessors, application-specific integrated circuits, application-specific instruction set processors, graphics processing units, logic units, coprocessors, digital signal processing units, audio processing units, etc.

[0231] Furthermore, the second controller decodes the first acoustic wave signal to obtain interaction information. The second controller then sends a fifth acoustic wave signal containing confirmation information corresponding to the interaction information to the first device (vehicle). The first controller of the first device (vehicle) decodes the fifth acoustic wave signal to obtain confirmation information corresponding to the interaction information. The terminal device then presents the confirmation information containing the interaction information to the user for confirmation.

[0232] Furthermore, after the user confirms the request, the first controller can encode the user's confirmation instruction and the device information of the first device together (or can encode and send a separate acoustic signal), generate a third acoustic signal, and send this signal to the second device (charging station). The second controller can convert the third acoustic signal into an electrical signal and send it to the server via the first communication module for analysis. The server can then recover the interaction information through the analysis operation, which includes transaction information and authentication information. Based on the authentication information, the server authenticates the first device. Once the authentication is successful, the server can call a preset payment channel interface or upload the relevant transaction information to a third-party transaction settlement platform for payment deduction or order processing. After completing the settlement transaction, the server sends the transaction result and authentication result back to the second device (charging pile). The second controller in the second device (charging pile) encodes the transaction result and returns it to the first device (vehicle) in the form of a sound wave signal (i.e., the second sound wave signal). At the same time, the second controller can also encode the authentication result and return it to the first device (vehicle) in the form of a sound wave signal (i.e., the fourth sound wave signal). The first controller in the vehicle can extract and analyze the sound wave characteristic value by decoding the signal, thereby obtaining the transaction result and authentication result, and further display the transaction result and authentication result on the vehicle screen for the user to view.

[0233] Based on the interaction method described in the above embodiment, Figure 9 Describe the interaction logic between the first device, the second device, and the third device.

[0234] Figure 9 is a flow chart of the interaction logic between the first device, the second device and the third device according to one embodiment of the present invention. Figure 9 As shown, if the first device is a vehicle, the second device is a charging station, and the third device is a camera, when a program within the host computer of the first device (vehicle) actively detects a sonic interaction request, or when the second device (charging station) sends a sonic interaction request to the vehicle by calling a preset API interface, the first controller in the first device (vehicle) can receive the interaction request and obtain interaction information based on the interaction request. The first controller encodes the interaction information to obtain a sonic signal whose acoustic characteristics match the target interaction information. The first controller then generates a corresponding pulse-width modulation (PWM) signal based on the sonic signal. The PWM signal is transmitted to the inverter. The inverter controls the current magnitude and frequency in the stator coil of the first motor according to the duty cycle of the PWM signal, causing the first motor to generate mechanical vibrations of a specific frequency and loudness, thereby emitting a first sonic signal containing the interaction information. This sonic signal can have no specific propagation direction. Of course, if required, the specific vehicle structure can also be used to make the sonic signal emitted by the motor propagate in a directional manner.

[0235] Furthermore, the second device (charging station) can capture the sound wave signal containing the interaction information through its built-in sound wave detection module (such as a microphone), and perform processing such as enhancement, filtering, and denoising on the first sound wave signal to extract the effective sound wave signal from the ambient noise, filter out the interference signal, and perform analog-to-digital conversion to generate a digitized sound wave signal sequence. The first sound wave signal containing the interaction information is then decoded to obtain the interaction information.

[0236] Furthermore, after receiving and parsing the interaction information, the second device (charging station) generates a confirmation message to ensure the transaction is authorized by the legitimate user and to prevent erroneous operations or unauthorized automated transactions. This confirmation message is then encoded with the interaction information to create a corresponding fifth acoustic signal, which is then transmitted to the first device (vehicle). Upon receiving the fifth acoustic signal, the first device (vehicle) presents the confirmation message, including the interaction information, to the user via a terminal device for confirmation. Once the user verifies the transaction details are correct, they click the "Confirm" button on the terminal device's interface. The first device (vehicle) then encodes the user's confirmation instruction and the interaction information, modulates it into an acoustic signal, and transmits it. The second device (charging station) receives the acoustic signal containing the confirmation instruction, decodes it, and obtains the confirmation instruction and interaction information. The interaction information is then uploaded to the server. Based on the transaction information contained in the interaction information, the server calls the transaction settlement platform for settlement processing.

[0237] Furthermore, the third device (camera) can capture vehicle image information through its internal image acquisition module and analyze the image using an image recognition algorithm to extract identifiable features of the vehicle to further obtain the vehicle's device information. This device information may include, but is not limited to, the vehicle's license plate and vehicle model. Using the identified license plate and vehicle model information, the corresponding vehicle registration information, such as the owner's payment information and associated payment channels, can be retrieved or matched. Based on this vehicle information, an identification code uniquely corresponding to the first device can be generated. The license plate information, vehicle model information, payment information, associated payment channels, and identification code are then combined to generate authentication information for the first device (vehicle). This authentication information is then sent to the second device (charging station) for subsequent authentication on the server.

[0238] Furthermore, the server authenticates the first device (vehicle) based on the received authentication information, including verifying data integrity, validating the transaction legitimacy, and identifying the transacting user, thereby preventing forgery or tampering of the information. After the server completes the authentication process, the second controller receives the authentication result from the server. The authentication result may include information such as "authentication successful" or "authentication failed." The second controller may encode the authentication result to generate second feedback information. The second controller controls the acoustic wave transmission module to transmit a fourth acoustic wave signal containing the second feedback information to the vehicle. The first acoustic wave receiving module in the first device (vehicle) receives the fourth acoustic wave signal containing the second feedback information and converts the collected analog acoustic wave signal into a digital signal. The decoding module built into the first controller demodulates and restores the received fourth acoustic wave signal based on preset decoding rules, extracting the valid second feedback information from it and providing feedback on the authentication result, either in real time on the terminal device or via voice broadcast.

[0239] At the same time, the second controller can also receive the transaction results sent by the server. The transaction results may include information such as "transaction successful" or "transaction failed". The second controller can encode the transaction results and generate first feedback information. The second controller controls the sound wave transmitting module to transmit a second sound wave signal containing the first feedback information to the first device (vehicle). The first sound wave receiving module in the vehicle can receive the second sound wave signal containing the first feedback information and convert the collected analog sound wave signal into a digital signal. The decoding module built into the first controller can demodulate and restore the received second sound wave signal based on preset decoding rules, extract the valid first feedback information from it, and display the transaction results in real time on the terminal device or through voice broadcast to ensure that the user is aware of the transaction status in a timely manner.

The first device 1, the second device 2, the third device 3 and the server 4 communicate to implement the interactive method described in the above embodiment.

[0270] According to the interactive system 100 of an embodiment of the present invention, the first device 1, the second device 2, the third device 3 and the server 4 can realize the function of directly using motors to perform sound wave interaction by adopting the interaction method described in the above embodiment, without relying on additional sound wave emitting devices, reducing the demand for additional hardware equipment, reducing equipment costs, and avoiding the risk of damage to additional hardware equipment, thereby improving the reliability of interaction.

[0277] Reference below Figure 15 A first device according to an embodiment of the present invention is described.

[0278] Figure 15 is a block diagram of a first device according to an embodiment of the present invention, such as Figure 15 As shown, the first device 1 according to the embodiment of the present invention includes: a first motor 11 and a first controller 12 .

[0279] In some embodiments, the first motor 11 can include any AC or DC motor, such as a single-phase motor, a multi-phase motor, or an induction motor. The motor 11 can be configured in multiple operating states, such as a sound wave generating state, a driving state, a power generation state, a boost charging state, and a heating state. When operating in the sound wave generating state, the electric vehicle is in a parking or driving state.

[0280] In some embodiments, the first controller 12 is connected to the first motor 11 for executing the interaction method described in the above embodiments.

[0281] According to an embodiment of the present invention, a first device 1 includes a first controller 12 connected to a first motor 11. By executing the interaction method described in the above embodiment, the first motor 11 can be controlled to vibrate, thereby emitting a first acoustic signal of a specific frequency and loudness. This signal carries the interaction information, thereby enabling acoustic transmission of information. Because this method directly reuses the first motor 11 already in the first device 1 as the source of the acoustic signal, eliminating the need for a dedicated acoustic transmitter (such as a speaker or ultrasonic module), it effectively reduces reliance on external hardware devices, lowering the overall hardware complexity and cost of the system. Furthermore, since the first motor 11 itself is a standard component of the first device 1, its stability and reliability have been fully verified. Its relatively fixed position and strong environmental adaptability make it less susceptible to damage due to external environmental influences. This avoids the risk of damage to independent acoustic transmitters in the prior art, thereby improving the reliability of the interaction.

[0282] In some embodiments, the first device 1 further includes an inverter 13 , which is connected to the first motor 11 and the first controller 12 and is configured to drive the first motor 11 to emit a sound wave signal.

[0283] Specifically, the vehicle-mounted host in the first device 1 can actively monitor whether there is a sound wave interaction request from the second device 2. The sound wave interaction request can include the device identification (ID) of the second device 2 and the data content to be transmitted, that is, the interaction information. The vehicle-mounted host can transmit the interaction information to the first controller 12. The first controller 12 encodes the interaction information to generate a sound wave signal whose sound wave characteristics match the interaction information, and then generates a corresponding pulse width modulation (PWM) signal based on the sound wave signal. By transmitting the PWM signal to the inverter 13, the inverter 13 controls the current size and frequency in the stator coil of the first motor according to the duty cycle of the PWM signal, so that the first motor 11 generates mechanical vibrations of a specific frequency and loudness, thereby emitting a first sound wave signal containing the interaction information, thereby realizing the sound wave transmission of information.

[0284] In some embodiments, the first device 1 further includes: a first sound wave receiving module 14, for receiving a second sound wave signal containing first feedback information and / or receiving a fourth sound wave signal containing second feedback information, the first feedback information includes a transaction result, and the second feedback information includes an authentication result.

[0285] The first sound wave receiving module 14 can be any sound wave receiving device installed on the electric vehicle, such as a built-in microphone, an external microphone, a specific frequency sound wave sensing device, etc.

[0286] In some embodiments, the first sound wave receiving module 14 can collect the second sound wave signal containing the first feedback information and / or receive the fourth sound wave signal containing the second feedback information, and convert the collected analog sound wave signal into a digital signal for subsequent processing. The decoding module built into the first device 1 can demodulate and restore the received second sound wave signal and / or fourth sound wave signal based on preset decoding rules to extract the first feedback information and / or the second feedback information therefrom.

[0287] In some embodiments, the first device 1 further includes: a terminal device 15 , which is connected to the first controller 12 and is configured to interact with the user to obtain a confirmation instruction from the user regarding the interaction information.

[0288] Among them, the terminal device 15 can be a vehicle-mounted central control screen, instrument panel, voice interaction module or HUD, etc., which is presented to the user in a graphical and voice manner through the terminal device 15 of the first device 1, thereby improving the interaction transparency and user experience.

[0289] In some embodiments, the first device 1 includes a vehicle. The vehicle can act as an active or passive party in the acoustic wave interaction and can exchange information with a second device including a charging station, a parking gate, a gas station terminal, an access control system, an unmanned store, and the like.

[0290] Reference below Figure 16 The second device according to the embodiment of the present invention is described. The second device may be a charging pile, a parking gate, a gas station terminal, an access control system, etc.

[0291] Figure 16 is a block diagram of a second device according to an embodiment of the present invention, such as Figure 16 As shown, the second device 2 according to the embodiment of the present invention includes: a second sound wave receiving module 21 and a second controller 22 .

[0292] In some embodiments, the second sound wave receiving module 21 may be a microphone array or a sound wave sensor, configured to receive a first sound wave signal emitted by the first motor 11 of the first device 1 , and the first sound wave signal includes interaction information.

[0293] In some embodiments, the controller 22 is connected to the second sound wave receiving module 21 and is used to execute the interaction method described in the above embodiment, and is responsible for receiving signals from the second sound wave receiving module 21 and performing corresponding processing operations.

[0294] According to the interaction method of an embodiment of the present invention, the second sound wave receiving module 22 is configured to receive a first sound wave signal emitted by the first motor 11 of the first device 1. Specifically, after receiving an interaction request, the first controller 12 controls the first motor 11 to vibrate, thereby emitting a first sound wave signal of a specific frequency and loudness. This signal carries the interaction information, thereby enabling acoustic transmission of information. Because this method directly reuses the first motor 11 already in the first device 1 as the source of the sound wave signal, eliminating the need for a dedicated sound wave transmitter (such as a speaker or ultrasonic module), it effectively reduces reliance on external hardware devices, lowering the overall hardware complexity and cost of the system. Furthermore, since the first motor 11 is a standard feature of the first device 1, its stability and reliability have been fully verified. Its relatively fixed position and strong environmental adaptability make it less susceptible to damage due to external environmental influences. This avoids the risk of damage to independent sound wave transmitters in the prior art, thereby improving the reliability of the interaction.

[0295] In some embodiments, the second device 2 further includes an acoustic wave transmitting module 23. The acoustic wave transmitting module 23 is connected to the second controller 22 and is configured to transmit at least one of a second acoustic wave signal containing the first feedback information, a fourth acoustic wave signal containing the second feedback information, and a fifth acoustic wave signal containing the second feedback information, wherein the first feedback information includes a transaction result, the second feedback information includes an authentication result, and the fifth acoustic wave signal includes confirmation information corresponding to the interaction signal.

[0296] In some embodiments, the acoustic wave transmitting module 23 may include, but is not limited to, an acoustic wave oscillator, a speaker, and a signal modulator. The acoustic wave oscillator may be responsible for generating vibrations of a specific frequency, the speaker may convert electrical signals into acoustic wave signals, and the signal modulator may be used to encode feedback information into an acoustic wave signal suitable for transmission.

[0297] In some embodiments, the second device 2 further includes: a first communication module 24 , which is connected to the second controller 22 and is used to communicate with the server 4 or the third device 3 .

[0298] In some embodiments, the first communication module 24 can establish a connection with the server 4 or the third device 3 via a standard wireless communication protocol (such as Wi-Fi, Bluetooth, 4G / 5G, etc.). Through this communication, the second device 2 can receive authentication information sent from the third device 3 and can send authentication information and interaction information including transaction information to the server 4. Simultaneously, the second device 2 can also receive first feedback information and second feedback information regarding the interaction information transmitted by the server 4.

[0299] Reference below Figure 17 The third device according to an embodiment of the present invention is described, and is used to communicate with the second device 2 described in the above embodiment. The third device may be an image acquisition device such as a camera.

[0300] Figure 17 is a block diagram of a third device according to an embodiment of the present invention, such as Figure 17 As shown, the third device 3 of the embodiment of the present invention includes: an image acquisition module 31 , an image processing module 32 and a second communication module 33 .

[0301] In some embodiments, the image acquisition module 31 may be a camera or other types of image sensing devices, used to acquire image information of the first device 1 , wherein the first device 1 is a device for sending a first acoustic wave signal of interactive information.

[0302] In some embodiments, the image acquisition module 31 can also determine whether the range of the first device 1 is within the recognition area of ​​the second device 2. By identifying the position of the first device 1, it can be used to adjust the direction of the sound wave transmitting module 23 or the sound wave receiving module 21 of the second device 2 to improve the success rate of the sound wave interaction.

[0303] In some embodiments, the image processing module 32 is connected to the image acquisition module 31 and is configured to execute the interaction method described in the above embodiments. Specifically, image recognition technology is used to extract device information from the image. This device information includes, but is not limited to, the device ID, device model, manufacturer information, and device configuration of the first device 1. To extract useful device information from the image, the image processing module 32 may utilize image processing algorithms such as feature matching, template recognition, optical character recognition (OCR), and machine learning methods. Using these technologies, the image processing module 32 can accurately identify and extract the device information of the first device 1.

[0304] In some embodiments, the second communication module 33 is connected to the image processing module 32 and is configured to transmit the processed authentication information to the second device 2. Specifically, if the first device 1 is a vehicle, the identified license plate and vehicle model information is used to further retrieve or match the corresponding vehicle registration information, such as the owner's payment information and associated payment channels. Based on this vehicle information, an identification code uniquely corresponding to the first device 1 can be generated. The license plate information, vehicle model information, payment information, associated payment channels, and the identification code are then combined to generate authentication information for the first device 1. This authentication information is then transmitted to the second device 2 for subsequent authentication on the server 4.

[0305] In some embodiments, the second communication module 33 can also be used to transmit sound wave transmission and reception direction adjustment information. Specifically, the third device 3 can transmit the sound wave transmission and reception direction adjustment information to the second device 2 via wireless communication (such as Wi-Fi, Bluetooth, etc.). Upon receiving the sound wave transmission and reception direction adjustment information, the second device 2 will adjust the direction of its sound wave receiver or transmitter accordingly. This approach ensures that the transmission of sound wave signals is not interfered with and maximizes the quality of signal reception.

[0306] In some embodiments, the second communication module 33 can support multiple communication protocols, such as Wi-Fi, Bluetooth, Zigbee, etc. It can provide necessary security protection during data transmission, such as using TLS / SSL protocol to encrypt communication to ensure data privacy and integrity.

[0307] According to the third device 3 of the embodiment of the present invention, the image processing module 32 is connected to the image acquisition module 31. By identifying the image information of the first device 1 captured by the image acquisition module 31, it can extract device information including the first device's identification or attributes, thereby generating authentication information. This authentication information is then transmitted to the second device 2 via the second communication module 33. This authentication method effectively prevents interception, replay, or tampering attacks, thereby improving transaction security. Furthermore, the first acoustic signal containing the interaction information is generated by the first motor 11 in the first device 1. Specifically, after receiving the interaction request, the first controller 12 controls the first motor 11 to vibrate, thereby emitting a first acoustic signal of a specific frequency and loudness. This signal carries the interaction information, thereby enabling acoustic transmission of information. Because this method directly reuses the first motor 11 already in the first device 1 as the acoustic signal source, it eliminates the need for a dedicated acoustic transmitter (such as a speaker or ultrasonic module). This effectively reduces reliance on external hardware devices, lowering the overall hardware complexity and cost of the system. In addition, since the first motor 11 itself is the original standard configuration of the first device 1, its stability and reliability have been fully verified, its position is relatively fixed, its environmental adaptability is strong, and it is not easily damaged by external environmental influences, thus avoiding the risk of independent sound wave emitting devices in the existing technology being easily damaged in the external environment, thereby improving the reliability of the interaction.
