Description

Technical Field

[0001] This invention relates to the field of sound control technology, and more particularly to a sound control system and method for vehicles. Background Technology

[0002] Vehicles are equipped with multiple doors. Most doors are located on the sides of the vehicle for passenger entry and exit. Additionally, doors may include a front trunk lid, a trunk lid, or a tailgate. In the case of a sedan-type passenger car, a trunk lid is located at the rear. In the case of other types of vehicles such as sport utility vehicles (SUVs), recreational vehicles (RVs), or vans, a tailgate is located at the rear. Trunk lids or tailgates provide ample and open loading space. To further increase loading space, in addition to a rear trunk lid or tailgate, many vehicles (e.g., electric vehicles) have a front trunk lid.

[0003] Taking the tailgate as an example, current vehicles are equipped with automatically opening tailgates, allowing them to open automatically when a user with a smart key approaches within a predetermined distance. However, the tailgate can also open automatically when the user approaches without intending to open it. For instance, if a user with a smart key is washing the back of the vehicle, talking in the back, or a child playing in the back, the tailgate may open unintentionally. Furthermore, there are hands-free tailgate systems. With these systems, when the user is carrying packages, they must lift their foot and kick it into the detection range of a sensor located at the bottom inside the rear bumper. However, this can happen if the user's kicking motion is inaccurate, preventing the tailgate from opening, or if the user needs to maintain the kicking position for too long, causing them to fall.

[0004] The above description of the background technology is only for the purpose of facilitating a deeper understanding of the technical solution of the present invention (the technical means used, the technical problems solved, and the technical effects produced, etc.), and should not be regarded as an admission or in any form an implication that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a vehicle voice control system and method. More specifically, when a vehicle user carrying a mobile device approaches the vehicle, the tailgate / rear trunk / front trunk can be opened by saying "open tailgate / rear trunk / front trunk".

[0040] The following provides a detailed description of the embodiments of the present invention. These embodiments are implemented based on the technical solution of the present invention, and provide detailed implementation methods and specific operation processes. However, the scope of protection of the present invention is not limited to the following embodiments.

[0041] Figure 1 This is a block diagram of a sound control system according to an embodiment of the present invention. Figure 1 As shown, a vehicle sound control system 100 according to an embodiment of the present invention includes a communication device 110, a sound receiving device 120, and a sound control device 130. When a mobile device 200 carried by a vehicle user enters the detection range of the communication device 110, the communication device 110 communicates with the detected mobile device 200 to detect the location of the mobile device 200 and whether the mobile device 200 is authorized. The sound receiving device 120 is configured to receive the user's voice information. In response to detecting that an authorized mobile device 200 has entered the detection range of the communication device 110, the sound control device 130 controls the sound receiving device 120 to receive sound information from outside the vehicle, which includes at least sound information for controlling the vehicle doors. Furthermore, the sound control device 130 is configured to identify the sound information received from the sound receiving device 120, and based on the identification result, control the corresponding target vehicle-mounted equipment 140, including the vehicle doors. The vehicle doors may include a tailgate, a trunk door, or a front trunk door.

[0042] Therefore, when a vehicle user carrying a mobile device 200 (such as a smart key) approaches the vehicle (specifically, enters the detection range), they can open the tailgate / trunk / front trunk by saying "Open tailgate / trunk / front trunk". This avoids the inconvenience of the door automatically opening when the vehicle user approaches the door without intending to open it, or the inconvenience of operating the door by kicking it.

[0043] Specifically, the sound receiving device 120 can be a microphone 121.

[0044] The microphone 121 can be installed on the left / right exterior rearview mirror 171 of the vehicle. Figure 2 This is a schematic diagram showing a microphone installed in the left / right exterior rearview mirror of a vehicle. The position of the microphone 121, which protrudes from the vehicle's outline, ensures that it can receive sounds from outside the vehicle well, especially suitable for receiving sounds when the vehicle user wants to control the front trunk door.

[0045] The microphone 121 can also be installed on the tailgate 141 or the trunk door. Figure 3 This is a schematic diagram showing the location of the microphone installed on the tailgate of the vehicle. (For example...) Figure 3 As shown, microphone 121 can be positioned on the edge of tailgate 141, and when tailgate 141 is fully closed, microphone can be hidden between tailgate 141 and vehicle body 170, thus being unaffected by weather conditions. The location of microphone 121 on tailgate 141 or trunk is suitable for receiving sound when vehicle users wish to control tailgate 141 or trunk door.

[0046] In addition, microphone 121 can also be a microphone 121 located inside a mobile device.

[0047] Figure 4 This is a schematic diagram of a communication device according to an embodiment of the present invention. Figure 4 As shown, the communication device 110 may include multiple Ultra-Wideband (UWB) sub-devices 111, a UWB Bluetooth Low Energy (BLE) master device 112, and a Body Domain Controller (BDC) 113. Each UWB sub-device 111 and UWB BLE master device 112, located at the four corners of the vehicle, in the passenger compartment, and in the trunk, communicates with the BDC 113 via the Local Controller Area Network (L-CAN). Each UWB sub-device 111 can communicate with the UWB BLE master device 112 via the vehicle's L-CAN. The UWB sub-devices 111 and UWB BLE master device 112 communicate with the mobile device 200.

[0048] Figure 5 This is a schematic diagram showing the locations of multiple UWB sub-devices. For example... Figure 5 As shown, multiple UWB sub-devices 111 are disposed in multiple locations on the vehicle. Specifically, the multiple UWB sub-devices 111 may include at least a first UWB sub-device 111a to a sixth UWB sub-device 111f. The first UWB sub-device 111a is disposed on the front left side of the vehicle body, the second UWB sub-device 111b is disposed on the front right side of the vehicle body, the third UWB sub-device 111c is disposed on the rear left side of the vehicle body, the fourth UWB sub-device 111d is disposed on the rear right side of the vehicle body, the fifth UWB sub-device 111e is disposed in the vehicle passenger compartment (specifically, on the roof along the vehicle's central axis and corresponding to above the rear seats), and the sixth UWB sub-device 111f is disposed in the vehicle trunk (specifically, in the trunk along the vehicle's central axis).

[0049] BDC 113 sends a transmission request signal to UWB sub-device 111. When UWB sub-device 111 receives the transmission request signal from BDC 113, it can transmit a request signal. Each of the first UWB sub-devices 111a to the sixth UWB sub-device 111f can transmit a request signal, meaning the request signal can be transmitted from the corresponding UWB sub-device 111. The request signal has a transmission radius of a predetermined distance, thereby forming a detection area that can cover the exterior of the vehicle within the predetermined range.

[0050] When a mobile device 200 (e.g., a smartphone) enters the detection area formed by the request signal, the mobile device 200 can send a response signal in response to the request signal. The UWB sub-device 111 can receive the response signal from the mobile device 200.

[0051] When the mobile device 200 is far from the vehicle, the UWB BLE master device 112 first performs positioning via BLE. When the mobile device 200 is closer to the vehicle, it then performs precise positioning via UWB. During the precise positioning by the UWB BLE master device 112, the UWB BLE master device 112 can detect the position of the mobile device 200 based on the response signal of the mobile device 200 and the request signal of the UWB sub-device 111.

[0052] Specifically, the UWB sub-device 111 sends the response signal received from the mobile device 200 to the UWB BLE master device 112. Since the UWB sub-device 111 can transmit request signals at preset time intervals, and the UWB BLE master device 112 can receive the response signal from each UWB sub-device 111, the UWB BLE master device 112 can determine the time point at which the response signal is provided. Therefore, the UWB BLE master device 112 can measure the time delay between the request signal and the response signal. Because multiple UWB sub-devices 111 are spatially distributed and all communicate with the mobile device 200, the UWB BLE master device 112 can calculate the precise location of the mobile device 200 by measuring the difference in time delay between the mobile device 200 and each UWB sub-device 111, using methods such as triangulation. However, the invention is not limited to this; the UWB BLE master device 112 can accurately calculate the location of the mobile device 200 using other UWB positioning algorithms.

[0053] Furthermore, the present invention is not limited to using UWB sub-device 111 and UWB BLE master device 112, wherein UWB sub-device 111 can be replaced by BLE sub-device.

[0054] Currently, positioning methods based on low frequency (LHF) and radio frequency (RF) can only detect the area where the mobile device 200 is located, and may not be able to accurately detect the location of the mobile device 200. However, the UWB-based positioning method according to the embodiment of the present invention can accurately detect the location of the mobile device 200.

[0055] In addition, the response signal of the mobile device 200 includes the authentication information of the mobile device 200. The UWB BLE master device 112 can compare the authentication information of the mobile device 200 with the pre-stored authentication information. When the authentication information in the response signal of the mobile device 200 matches one of the pre-stored authentication information, the UWB BLE master device 112 can detect that the mobile device is authorized.

[0056] The UWB BLE master device 112 sends the detection results (including the location of the mobile device 200 and whether the mobile device 200 is authorized) to the BDC 113. After receiving the detection results, the BDC 113 can send a wake-up command to the voice control device 130.

[0057] Specifically, the voice control device 130 can be implemented through the vehicle's audio, video, navigation, and telematics (AVNT).

[0058] Figure 6 This is a block diagram illustrating the detailed structure of a vehicle's sound control system according to an embodiment of the present invention. Figure 6 As shown, after receiving the wake-up command from BDC 113, AVNT 131 can control the microphone 121 located outside the vehicle to operate in order to receive the user's voice information.

[0059] As described above, the positions of microphones 121 on the left / right exterior rearview mirrors are suitable for receiving sound when the vehicle user wishes to control the front trunk door, and the positions of microphones 121 on the tailgate 141 or trunk are suitable for receiving sound when the vehicle user wishes to control the tailgate 141 or trunk door. Therefore, preferably, during the operation of microphones 121 controlled by AVNT 131, AVNT 131 can activate microphones 121 at the corresponding positions based on the position of the mobile device detected by UWB BLE master device 112. That is, when the mobile device is located at the rear of the vehicle, only the microphones 121 located at the tailgate 141 or trunk are operational; when the mobile device is located at the front of the vehicle or the side of the vehicle, only the microphones 121 located on the left / right exterior rearview mirrors are operational. Thus, problems such as noise intrusion and sound recognition error delays caused by microphones 121 being operational in all positions can be prevented.

[0060] While the microphone 121 located on the left / right exterior rearview mirror is in operation, the BDC 113 can control the left and right exterior rearview mirrors 150 of the vehicle to unfold via the Side Body Control Module (SBCM) 163, thereby reminding the vehicle user that the microphone 121 is receiving sound information from outside the vehicle.

[0061] When a vehicle user emits a sound message, the microphone 121 can receive the sound message and send it to the AVNT 131. The AVNT 131 identifies the sound message received from the microphone and controls the corresponding target vehicle device 140 based on the identification result.

[0062] When microphone 121 is located inside the mobile device, voice control device 130 can be implemented via the mobile device and AVNT 131. The mobile device can identify the received sound information to obtain the identification result. After receiving the wake-up command from BDC 113, AVNT 131 can establish a connection with the mobile device. Therefore, the mobile device can send the identification result to AVNT 131, and AVNT 131 can control the corresponding target vehicle device 140 based on the identification result.

[0063] Specifically, AVNT 131 can send control commands to BDC 113, which acts as the main controller. After processing the control commands received from AVNT 131, BDC 113 can send control commands to the control unit 160 of the target vehicle device 140. The control unit 160 controls the target vehicle device 140 according to the received control commands.

[0064] Specifically, the audio information may include audio information for controlling the vehicle doors, and correspondingly, the target vehicle-mounted device 140 includes a vehicle door. Since the vehicle door may include a tailgate 141, a trunk door 142, or a front trunk door 143, the control unit 160 may include a Power Tail Gate (PTG) controller 161 for controlling the tailgate 141, a Power Trunk Lid (PTL) controller 162 for controlling the trunk door 142, and an SBCM 163 for controlling the front trunk door 143. The AVNT 131 and BDC 113 can communicate via a Communication Control Unit (CCU) 132, and the BDC 113 can communicate with each of the control units 160.

[0065] Figure 7AThis is a schematic diagram illustrating the state when a vehicle user intends to open the front trunk door. The vehicle user may approach the vehicle with a smart key, for example, as shown in Figure 7, the vehicle user may be positioned to the side of the vehicle. The vehicle user's position is both within the sound receiving range of the microphone 121 located on the left / right exterior rearview mirrors 171 and within the detection range of the communication device 110. At this time, the AVNT 131 can activate the control microphone 121. When the vehicle user says "Open front trunk door," the microphone 121 located on the left / right exterior rearview mirrors 171 can receive the sound information "Open front trunk door" and send the sound information to the AVNT 131. The AVNT 131 can identify the sound information received from the microphone 121. Specifically, the AVNT 131 can identify the target type that the vehicle user intends to set, such as "front trunk door," and the action mode of that target type, such as "open." Thus, based on the identification result, the AVNT 131 controls the SBCM 163 to operate via the BDC 113, and the front trunk door 143 can be opened.

[0066] Figure 7B This is a schematic diagram illustrating the state when a vehicle user intends to open the vehicle's tailgate or trunk. For example, a user of a vehicle equipped with a tailgate 141 might approach the vehicle with a smart key. For example, as... Figure 7B As shown, the vehicle user can be positioned at the rear of the vehicle and close to the tailgate 141. The user's location is within the sound receiving range of the microphone 121 located on the tailgate 141 and also within the detection range of the communication device 110. At this time, the AVNT 131 can activate the microphone 121. When the vehicle user says "tailgate open," the microphone 121 on the tailgate 141 can receive the sound information "tailgate open" and send it to the AVNT 131. The AVNT 131 can then identify the sound information received from the microphone 121. Specifically, the AVNT 131 can identify the target type the vehicle user wishes to set, such as "tailgate," and the action mode for that target type, such as "open." Based on the identification result, the AVNT 131 controls the PTG controller 161 via the BDC 113, allowing the tailgate 141 to open.

[0067] Back Figure 1According to an embodiment of the present invention, the vehicle's sound control system 100 may further include a sound output device 150, and the sound control device 130 may control the sound output device 150 to output the control result of the target in-vehicle device 140 to the vehicle user. Therefore, the vehicle user can understand whether the control of the target in-vehicle device 140 has been completed through sound feedback. Furthermore, the embodiment of the present invention enhances the vehicle's intelligence through human-computer interaction. The sound output device 150 may be a speaker 151. The speaker 151 may be integrated with a microphone 121. For example, the PTG controller 161 may send the control result of the tailgate 141 to the AVNT 131, and the AVNT 131 may control the speaker 151 to output a sound such as "The tailgate is opening."

[0068] Furthermore, during the opening of a vehicle door (specifically, tailgate 141, trunk door 142, or front trunk door 143), the hazard warning lights 145 may flash and the buzzer 144 may sound to alert the vehicle user that the corresponding target on-board equipment 140 is being opened. Specifically, the PTG controller 161 or PTL controller 162 can control the buzzer 144 to sound, and the BDC 113 can send control commands to the integrated lamp control unit (ILCU) 165, thereby allowing the ILCU 165 to control the hazard warning lights 145 to flash.

[0069] Currently, the tailgate 141, trunk lid 142, or front trunk lid 143 do not automatically adjust their opening height according to the user's height. When the user is carrying packages with both hands, the doors opening too high or too low may cause inconvenience.

[0070] To address the aforementioned issues, in one implementation, since the communication device 110 (specifically, the UWB BLE master device 112) can detect the position of the mobile device 200, it can also detect the height of the mobile device 200 (which is part of the height information associated with the position of the mobile device 200). Since vehicle users typically carry packages with both hands, placing the mobile device 200 (e.g., a smart key and a mobile phone) in their pockets, the height of the mobile device 200 can reflect the height of the vehicle user. The voice control device 130 can receive the height of the mobile device 200 from the communication device 110. When the voice control device 130 controls the tailgate 141 to open based on the recognition result, it can adjust the opening height of the tailgate 141 according to the height of the mobile device 200. Therefore, the opening height of the tailgate 141 can be automatically adjusted based on the detected height of the mobile device 200 (i.e., the height of the vehicle user).

[0071] Figure 8This indicates the intention to show the tailgate opening based on the height of the detected mobile device. For example, according to... Figure 8 The height of the mobile device 200 shown is such that the opening height H of the tailgate 141 can be 90cm. If the height of the mobile device 200 is higher or lower, for example, the opening height of the tailgate 141 can be adjusted within the range of 30cm to 160cm.

[0072] In another embodiment, as described above, the communication device 110 (specifically, the UWB BLE master device 112) can compare the authentication information of the mobile device 200 with pre-stored authentication information to detect which of the pre-stored authentication information the authentication information in the response signal of the mobile device 200 corresponds to. Since the authentication information of the mobile device 200 can represent the vehicle user's identification (ID), the voice control device 130 can receive the authentication information of the mobile device 200 from the communication device 110. When the voice control device 130 controls the tailgate 141 to open based on the recognition result, the voice control device 130 can open the tailgate 141 to a height matching the user's height according to the authentication information. Therefore, the problem that different vehicle users have different body sizes (i.e., heights) and the tailgate 141 does not automatically adjust its opening height according to the vehicle user's height can be solved.

[0073] Specifically, back to Figure 1 According to an embodiment of the present invention, the vehicle voice control device 100 may include an input device 180 configured to acquire the correspondence between the verification information of the mobile device 200 and the opening height of the tailgate 141 preset by the vehicle user.

[0074] The input device 180 can be implemented by a touch screen integrated with the vehicle display terminal, which can be configured to have a settings interface. Figure 9A and Figure 9B This is a schematic diagram of a setting interface for adjusting the opening height of the tailgate according to an embodiment of the present invention. Figure 9A As shown, vehicle users can create user accounts such as User 2 and can choose to bind one of the following: smart key, Bluetooth key, or Blue Link key. Figure 9B As shown, when a vehicle user chooses to bind a smart key, pressing the lock button on the smart key will bind user 2 to the smart key. At this time, the verification information of the smart key is stored in the communication device 110 (specifically, the UWB BLE master device 112). When the vehicle user enters the detection range of the communication device 110 with the smart key, the communication device 110 can determine that the smart key is authorized and that the vehicle user's identity is user 2.

[0075] Subsequently, the vehicle user can set the opening height of the tailgate 144 in this user account. For example, for user 1, the tailgate opening height is set to 65cm, and for user 2, it is set to 60cm. The opening height of the tailgate 141 can be set within the range of 30cm to 160cm. Thus, the vehicle user completes the setup of the correspondence between the verification information of the mobile device 200 and the opening height of the tailgate 141.

[0076] Specifically, the settings interface can be accessed through the User Settings Menu (USM) in AVNT 131.

[0077] Similarly, the above-described implementation scheme for automatically adjusting the tailgate 141 according to the height of the vehicle user can be applied to the rear trunk 142 and the front trunk 143.

[0078] According to an embodiment of the present invention, vehicle users can not only control the opening or closing of the doors (specifically, the tailgate 141, the trunk door 142, or the front trunk door 143) by voice, but also control other target on-board devices 140 associated with the door opening or closing process by voice.

[0079] When a vehicle user loads a package at a door (e.g., tailgate 141), if the package is too large, the rear seats need to be folded down, and the front seats may even need to be moved or reclined to provide space. Currently, if a vehicle user wants to fold down the rear seats, they need to walk to the rear seat side door and use a switch or lever on the rear seat to fold it down. If a vehicle user wants to move the front seats or recline the front seat backrests, they need to walk to the front seat side door to control the front seats. However, a user may be carrying packages with both hands near tailgate 141, making seat adjustments inconvenient.

[0080] To solve the above problems, let's go back to... Figure 6 The audio information may include audio information for controlling the seat 146, such as "rear seat folding", "rear seat unfolding", "front seat moving forward", "front seat moving backward", or "front seat tilting". Accordingly, the control unit 160 may include an integrated memory system (IMS) unit 164 for controlling the seat 146.

[0081] Currently, the welcome and escort modes of the vehicle have fixed durations, such as 10 seconds, 20 seconds, or 30 seconds. Specifically, when the communication device 110 detects a vehicle user entering the detection range, the vehicle controller can control the light driver to illuminate the welcome lights for a predetermined time period to welcome the vehicle user before they get into the vehicle. When the vehicle has finished driving and the vehicle user gets out of the vehicle, the vehicle controller can control the light driver to illuminate the escort lights for a predetermined time period. The welcome lights or escort lights can be headlights, taillights, interior lights, exterior lights near the vehicle user's door, etc. Therefore, when a vehicle user is carrying a package from or near the vehicle in the dark (e.g., in an underground parking garage), the vehicle user needs to open the driver's side door and adjust the vehicle's power setting to Ignition 2 (IGN2). IGN2 refers to the power supply conditions required to power each auxiliary device needed to drive the vehicle; for example, IGN2 corresponds to the power supply conditions for wipers, air conditioning, sunroof, headlights, etc. Therefore, when the vehicle's ignition is in position 2, the vehicle user will have access to lighting. However, it may be inconvenient for the vehicle user to turn on the lighting when in a dark place (e.g., an underground parking garage) and while moving luggage in or near the vehicle.

[0082] To solve the above problems, let's go back to... Figure 6 The audio information may include audio information for controlling the headlights 147 or the taillights 148. For example, such audio information may include "turn on headlights", "turn off headlights", "turn on taillights", "turn off taillights", etc. Accordingly, the control unit 160 may include an ILCU 165 for controlling the headlights 147 or the taillights 148 to turn on or off.

[0083] In addition to adjusting the position of the seat 146 and controlling the lights, the audio information may also include audio information for controlling the windows 149 or the sunroof 172, such as "lower window" or "open sunroof". Accordingly, the control unit 160 may include a safety electronic control unit (Safety ECU) 166 for controlling the opening or closing of the windows 147 or the sunroof 172.

[0084] Specifically, in Figure 6In the specific implementation shown, AVNT 131 communicates with microphone 121, speaker 152, or CCU 132 via CAN. BDC 113 communicates with Safety ECU 166 via Local Interconnect Network (LIN). BDC 113 communicates with UWB sub-device 111, UWB master device 112, CCU 132, PTL controller 162, PTG controller 162, SBCM 163, ILCU 165, or IMS unit 164 via CAN.

[0085] The present invention also provides a method for controlling the sound of a vehicle. Figure 10 This is a flowchart of a vehicle sound control method according to an embodiment of the present invention. Figure 10 As shown, the vehicle voice control method includes: the communication device 110 detecting whether a mobile device 200 carried by a vehicle user has entered the detection range of the communication device 110 (S11). In response to the mobile device 200 entering the detection range of the communication device 110 (S11 "Yes"), the communication device 110 communicates with the detected mobile device 200 to detect the location of the mobile device 200 (S12), and the communication device 110 determines whether the mobile device 200 is authorized (S13).

[0086] In response to the determination that the mobile device 200 has entered the detection range of the communication device 110 and has been authorized ("Yes" in S13), the voice control device 130 controls the operation of the voice receiving device 120 (S14). The voice receiving device 120 receives sound information from outside the vehicle (S15), the sound information including at least sound information for controlling the doors, including the tailgate 141, the trunk door 142, or the front trunk door 143.

[0087] The voice control device 130 identifies the voice information received from the voice receiving device 120 (S16), and controls the corresponding target vehicle equipment 140, including the vehicle door, based on the identification result (S17).

[0088] Specifically, the step of the communication device 110 detecting the location of the mobile device 200 includes: multiple UWB sub-devices 111 or BLE sub-devices located at multiple locations in the vehicle transmitting request signals, which form a detection area outside the vehicle; and receiving a response signal sent by the mobile device 200 in response to the request signals when the mobile device 200 enters the detection area. The UWB BLE master device 112 detects the location of the mobile device 200 based on the response signal of the mobile device 200 and the request signals of the UWB sub-devices 111 or BLE sub-devices.

[0089] The step of the communication device 110 in detecting whether the mobile device 200 is authorized includes: the UWB BLE master device 112 comparing the authentication information of the mobile device 200 included in the response signal of the mobile device 200 with the pre-stored authentication information, and detecting that the mobile device 200 is authorized when the authentication information of the mobile device 200 matches one of the pre-stored authentication information.

[0090] The communication device may further include a BDC (Browser Control Center). The UWB BLE master device 112 sends the detection results (including the location of the mobile device 200 and the authorization of the mobile device 200) to the BDC 113. After receiving the detection results, the BDC 113 can send a wake-up command to the voice control device 130. Specifically, the voice control device 130 can be implemented through the vehicle's Audio Video Navigation Telematics (AVNT) 131. When the AVNT 131 receives the wake-up command, it controls the operation of the voice receiver 120 (specifically, the microphone 121).

[0091] The steps of the voice control device 130 controlling the car door include: the voice control device 130 receiving the position of the mobile device 200 from the communication device 110; when the voice control device 130 controls the car door to open according to the recognition result, the voice control device 130 adjusts the opening height of the car door according to the height of the mobile device.

[0092] The steps of the voice control device 130 controlling the car door include: the voice control device 130 receiving verification information from the communication device 110 from the mobile device 200; when the voice control device 130 controls the car door to open according to the recognition result, the voice control device 130 opens the car door to a height that matches the verification information of the mobile device 200.

[0093] The step of the voice control device 130 to open the car door at a height that matches the verification information of the mobile device 200 includes: obtaining the correspondence between the verification information of the mobile device 200 preset by the user and the height of the car door opening by the input device 180; when the voice control device 130 controls the car door to open according to the recognition result, the voice control device 130, based on the correspondence between the verification information of the mobile device 200 received from the input device 180 and the height of the car door opening, makes the car door open at a height that matches the verification information of the mobile device 200.

[0094] In addition to the audio information used to control the vehicle doors, the audio information may further include audio information used to control the seat 146, headlights 147, taillights 148, windows 149, or sunroof 172. Accordingly, the target vehicle equipment 140 includes the seat 146, headlights 147, taillights 148, windows 149, or sunroof 172.

[0095] The vehicle voice control method further includes the step of: the voice control device 130 controlling the voice output device 150 to output the control result of the target vehicle device 140 to the vehicle user.

[0096] According to the voice control system and method of the present invention, when a vehicle user carrying a mobile device 200 approaches the vehicle, the tailgate 141 / tailgate 142 / front trunk 143 can be opened by saying "open tailgate / rear trunk / front trunk". Therefore, the inconvenience of the door automatically opening when the vehicle user approaches the door without intending to open it, or the inconvenience of operating the door by kicking it, can be avoided.

[0097] In addition, the addition of voice control enhances human-computer interaction and improves the vehicle's intelligence.

[0098] Based on the sound control system and control method according to the embodiments of the present invention, the tailgate 141, the trunk door 142 or the front trunk door 143 can automatically adjust the opening height according to the height of the vehicle user, thereby making it convenient for the vehicle user to use.

[0099] In addition to controlling the tailgate 141, trunk 142, or front trunk 143 by voice, the driver can also control the seat 146, headlights 147, and / or taillights 148 by voice.
