Description

Technical Field

[0001] The present invention relates to the technical field of sound control, and in particular to a device and method for controlling a vehicle from outside the vehicle. Background Art

[0002] Voice recognition (VR) technology is widely used in the automotive sector to control navigation, music, calls, and in-car temperature. VR technology improves driver convenience and safety while driving. For example, while the vehicle is in motion, the driver can adjust the temperature by simply saying, "Raise the air conditioning temperature," without having to manually adjust the temperature using the air conditioning buttons. This eliminates the safety risks associated with operating the air conditioning buttons while driving.

[0003] However, current VR technology is only used inside the vehicle. In fact, the driver also needs to control the vehicle from outside the vehicle. Many operations outside the vehicle are achieved through the smart key (SMK), for example, the driver uses the smart key to unlock the door. If the driver can also control the vehicle through VR technology from outside the vehicle, it will further improve the convenience of operation. At the same time, controlling the vehicle from outside the vehicle through VR technology may bring new problems, such as security issues caused by allowing unidentified people to operate the vehicle from outside the vehicle.

[0015] The sound output device may be a speaker.

[0016] According to another embodiment of the present invention, a control method for controlling a vehicle from outside the vehicle is provided, comprising: identifying a vehicle user by a first safety detection device through a mobile device carried by the vehicle user; determining that a first safety condition is satisfied when the first safety detection device detects that the mobile device is close to the vehicle; converting a sound control device from a sleep state to an awake state when the first safety condition is satisfied; when the sound control device is in the awake state, controlling a sound receiving device by the sound control device to receive sound information from outside the vehicle; determining that a second safety condition is satisfied in response to a voiceprint of the sound information received from the sound receiving device by the second safety detection device being one of the pre-stored voiceprints; identifying the sound information by the sound control device when the second safety condition is satisfied; and outputting a control instruction to the corresponding target vehicle-mounted device based on the identification result.

Furthermore, the present invention provides safety guarantees for VR technology. That is, only after both the first safety condition and the second safety condition are met can the vehicle-mounted device be controlled by sound information from outside the vehicle, thereby ensuring vehicle safety.

For clarity, identical components in different drawings are indicated by identical reference numerals. It should be noted that the drawings are for illustrative purposes only and are not necessarily drawn to scale. In these drawings:

[0024] Figure 2 is a detailed block diagram of an apparatus for controlling a vehicle from outside the vehicle according to an embodiment of the present invention.

[0025] Figure 3 is a flowchart of a method for controlling a vehicle from outside the vehicle according to an embodiment of the present invention. DETAILED DESCRIPTION

[0026] The following is a detailed description of the implementation scheme of the present invention. This implementation scheme is implemented on the premise of the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following implementation scheme.

[0027] Figure 1 1 is a block diagram of an apparatus for controlling a vehicle from outside the vehicle according to an embodiment of the present invention. The apparatus for controlling a vehicle from outside the vehicle according to an embodiment of the present invention includes a sound receiving device 100, a first safety detection device 200, a second safety detection device 300, and a sound control device 400.

[0028] The sound receiving device 100 is configured to receive sound information from outside the vehicle. The first safety detection device 200 identifies the vehicle user through a mobile device 500 carried by the vehicle user. When the mobile device 500 is detected approaching the vehicle, the first safety condition is determined to be satisfied. The second safety detection device 300 compares the voiceprint of the sound information received from the sound receiving device 100 with pre-stored voiceprints. When the voiceprint of the sound information received from the sound receiving device 100 matches one of the pre-stored voiceprints, the second safety detection device 300 detects that the vehicle user has control authority, thus satisfying the second safety condition. The sound control device 400 is configured to: when the first safety condition is satisfied, transition from a dormant state to an awake state; in the awake state, control the sound receiving device 100 to receive sound information from outside the vehicle; and when the second safety condition is satisfied, identify the sound information received from the sound receiving device 100 and, based on the identification result, output a control instruction to the corresponding target vehicle-mounted device 600.

[0029] Therefore, according to the embodiment of the present invention, only after the first safety condition and the second safety condition are met, the vehicle-mounted device can be controlled by the sound information from outside the vehicle, thereby ensuring the safety of the vehicle. Specifically, whether the vehicle user has arrived at the designated location (i.e., around the vehicle) is detected, and the identification of the vehicle user is achieved through the mobile device 500 carried by the vehicle user, and the location of the mobile device 500 can be regarded as the location of the vehicle user. After detecting that the vehicle user has arrived at the designated location, the stored voiceprint can be used to detect whether the vehicle user identified by the mobile device 500 has a wider range of control authority. The confirmation of the control authority requires that its voice matches the stored voiceprint. For example, when a child carrying a mobile device (e.g., a smart key) is identified, since its voice does not match the stored voiceprint, the child cannot use voice input to control the vehicle function. Therefore, the safety problems caused by the child operating the vehicle from outside the vehicle are avoided.

[0030] The apparatus for controlling a vehicle from outside the vehicle may further include a sound output device 700. The sound control device 400 may control the sound output device 700 to output the control result of the target vehicle-mounted device 600 to the vehicle user. Therefore, the vehicle user can understand whether the control of the target vehicle-mounted device is completed through feedback in the form of sound.

[0031] In one example, when the sound control device 400 is in the awake state and before the second safety condition is met, the sound control device 400 can perform echo cancellation and noise reduction (ECNR) on the sound information received from the sound receiving device 100. Because the vehicle user is a certain distance away from the sound receiving device 100 and there is ambient noise, the sound information received from the sound receiving device 100 can be adjusted. Therefore, even when the vehicle user is far away from the vehicle and the ambient noise is loud, the sound information can be made clear, which facilitates the sound control device 400 to compare the voiceprint of the sound information and recognize the sound information in the subsequent process.

[0032] After the sound control device 400 recognizes the sound information, it can determine whether the sound information is valid. If the sound control device 400 determines that the sound information is valid, the sound control device 400 can output a control instruction to the corresponding target vehicle-mounted device 600 based on the recognition result. Conversely, if the sound control device 400 determines that the sound information is not valid, the sound control device 400 does not output a control instruction.

[0033] Figure 2 is a detailed block diagram of an apparatus for controlling a vehicle from outside the vehicle according to an embodiment of the present invention.

[0034] Reference Figure 1 and Figure 2 The sound receiving device 100 may be a microphone 110. Microphone 110 may be located in the left and right side rearview mirrors of the vehicle. The rearview mirrors provide a mounting space for microphone 110 that is protected from weather conditions. Furthermore, the protruding position of the rearview mirrors ensures that microphone 110 can effectively receive sounds outside the vehicle.

[0035] The first safety detection device 200 may include a communicator 210 and a body domain controller (BDC) 220 provided on the vehicle. In one example, when the vehicle is locked, the BDC 220 controls the communicator 210 to transmit a signal to search for the mobile device 500 within a predetermined search range. When a vehicle user carries the mobile device 500 and enters the search range, the mobile device 500 may receive a signal from the communicator 210 and, after receiving the signal from the communicator 210, transmit a signal to the BDC 220 via the communicator 210. When the BDC 220 receives the signal from the mobile device 500 via the communicator 210, the BDC 220 may identify the vehicle user and determine that the vehicle user has entered the search range, i.e., that the vehicle user is approaching the vehicle. After the BDC 220 determines that the vehicle user is approaching the vehicle, the BDC 220 may transmit a wake-up signal to the sound control device 400, causing the sound control device 400 to transition from a dormant state to an awake state.

[0036] Specifically, the communicator 210 may be any one of an ultra-wideband communication (UWB) antenna, a Bluetooth Low Energy (BLE) antenna, a Wireless Power Consortium (WPC) antenna, or a near field communication (NFC) antenna. Accordingly, the mobile device 500 may be any device capable of communicating with the BDC 220 via the communicator 210. For example, the mobile device 500 may be a smart key or a terminal device equipped with a digital key (DK) application. For example, the mobile device 500 may be a smartphone equipped with a DK 2.0 application.

[0037] The second safety detection device 300 and the sound control device 400 can be implemented by an audio video navigation telecommunication (AVNT) 800. Specifically, the AVNT 800 may include a microcontroller unit (MCU) 810, a central processing unit (CPU) 820, and a memory 830 provided in the AVNT 800.

[0038] The BDC 220 sends a wake-up signal to the AVNT MCU 810. When the AVNT MCU 810 receives the wake-up signal from the BDC 220, the AVNT 800 is awakened, that is, the AVNT CPU 820 is also awakened. After the AVNT CPU 820 is awakened, the AVNT CPU 820 controls the microphone 110 to start up. Specifically, the AVNT CPU 820 may send an activation signal to the microphone 110. After receiving the activation signal, the microphone 110 can receive sound information outside the vehicle.

[0039] When the AVNT CPU 820 receives sound information from outside the vehicle from the microphone 110, the AVNT CPU 820 may perform ECNR on the sound information received from the microphone 110. The AVNT CPU 820 then compares the voice print of the ECNR-processed sound information with pre-stored voice prints (specifically, pre-stored in the memory 830). If the voice print of the sound information received from the microphone 110 matches one of the pre-stored voice prints, the AVNT CPU 820 recognizes the sound information received from the microphone 110.

[0040] After the AVNT CPU 820 recognizes the sound information, it may determine whether the sound information is valid. If the AVNT CPU 820 determines that the sound information is valid, it may send the recognition result to the AVNT MCU 810. The AVNT MCU 810 may output a control instruction to the corresponding target in-vehicle device 600 based on the recognition result. If the AVNT CPU 820 determines that the sound information is not valid, it does not send the recognition result to the AVNT MCU 810.

[0041] Specifically, when the sound information includes a target type that is desired to be set and an action method of the target type, the AVNT CPU 820, that is, the sound control device 400, can determine that the sound information is valid.

[0042] Target types may include at least: the trunk lid, front trunk lid, charging door, window, sunroof, vehicle interior temperature, and steering wheel. Actions for target types may include at least: opening or closing one of the trunk lid, front trunk lid, charging door, window, or sunroof, raising or lowering the vehicle interior temperature, and turning the steering wheel to zero degrees. For example, valid voice messages may include "Open the trunk lid" or "Raise the temperature."

[0043] The target vehicle-mounted device 600 may include various vehicle electronic control units (ECUs) for controlling the above target types. The AVNT MCU 810 may communicate with each vehicle ECU using a communication control unit (CCU) 900 .

[0044] The vehicle ECU may include at least: one of a power tailgate monitor (PTGM) 601 and a power trunk lid (PTL) module 602, a roof control module (RCM) 603, a body zone control module (BCM) 604, a dual automatic temperature control (DATC) module 605, and a motor driven power steering (MDPS) module 606, etc.

[0045] When the vehicle is a sedan, a trunk lid 608 is provided at the rear of the vehicle, and the PTL module 602 is used to control the opening and closing of the trunk lid 608. When the vehicle is another type of vehicle, such as a sport utility vehicle (SUV), a tailgate 607 is provided at the rear of the vehicle, and the PTGM 601 is used to control the opening and closing of the tailgate 607. The RCM 603 can control the opening and closing of the sunroof 609. The BCM 604 can control the opening and closing of the windows 610, the charging door 611, and the front trunk lid 612. The DATC module 605 can control the temperature, that is, control the operation of the vehicle air conditioner 613. The MDPS module 606 can control the return of the steering wheel 614 to the center position.

[0046] Therefore, the target in-vehicle device 600 corresponding to the target type in the voice information can operate in the action mode in the voice information.

[0047] The sound output device 700 may be a speaker 710. The speaker 710 may be a speaker of a virtual engine sound system (VESS). The speaker 710 may be located outside the vehicle to improve sound transmission efficiency. Therefore, the vehicle ECU, having received control instructions from the AVNT MCU 810, may transmit the control results of the vehicle ECU to the AVNT MCU 810, and the AVNT CPU 820 may transmit an audio output signal regarding the control results to the speaker. When the speaker receives the audio output signal from the AVNT CPU 820, it may output audio to inform the vehicle user of the control results of the target in-vehicle device 600.

[0048] In addition, the BDC 220, AVNT MCU 810, AVNT CPU 820, and multiple vehicle ECUs can communicate with each other via a Controller Area Network (CAN). The microphone 110 and AVNT CPU 820, the AVNT CPU 820 and speaker 710, and multiple vehicle ECUs and corresponding actuators can be electrically connected by wire.

[0049] In the above-described specific embodiment of the present invention, the existing VESS speaker 710 and AVNT 800 are reused, and the control logic of the AVNT CPU 820 is improved, enabling the AVNT CPU 820 to perform ECNR, voiceprint comparison, and voice recognition. Therefore, compared to existing vehicle components, only the microphone 110 is added. Therefore, the cost of the additional components is limited, achieving the goal of no additional cost increase.

[0050] Another embodiment of the present invention further provides a method for controlling a vehicle from outside the vehicle, the method comprising: a first safety detection device 200 identifying a vehicle user through a mobile device 500 carried by the vehicle user; and upon detecting that the mobile device 500 is approaching the vehicle, determining that the vehicle user is approaching the vehicle, thereby determining that a first safety condition has been satisfied. When the first safety condition has been satisfied, a sound control device 400 transitions from a dormant state to an awake state, and while in the awake state, the sound control device 400 controls a sound receiving device 100 to receive sound information from outside the vehicle. A second safety detection device 300 compares the voiceprint of the sound information received from the sound receiving device 100 with a pre-stored voiceprint. When the voiceprint of the sound information received from the sound receiving device 100 matches one of the pre-stored voiceprints, determining that the vehicle user carrying the smart key 500 is a vehicle user with control authority, thereby determining that a second safety condition has been satisfied.

[0051] In one example, when the sound control device 400 is in the awake state, before the second safety condition is satisfied, the sound control device 400 can perform ECNR on the sound information received from the sound receiving device 100 .

[0052] When the second safety condition is satisfied, the sound control device 400 recognizes the sound information received from the sound receiving device 100 and outputs a control instruction to the corresponding target vehicle-mounted device 600 according to the recognition result.

[0053] For example, after the sound control device 400 recognizes the sound information, it determines whether the sound information is valid. If the sound information is determined to be valid, the sound control device 400 outputs a control instruction to the corresponding target vehicle-mounted device 600 based on the recognition result. Specifically, the sound information can be determined to be valid when the sound information includes a desired target type and an action method for the target type.

[0054] Furthermore, the sound output device 700 is controlled by the sound control device 400 to output the control result of the target vehicle-mounted device to the vehicle user.

[0055] Specifically, the sound receiving device 100 may be a microphone 110, and the first safety detection device 200 may include a communicator 210 and a BDC 220 provided on the vehicle. The second safety detection device 300 and the sound control device 400 may be implemented by an AVNT 800. The sound output device 700 may be a speaker 710.

[0056] Figure 3 FIG. 1 is a flow chart of a method for controlling a vehicle from outside the vehicle according to an embodiment of the present invention. Figure 3 As shown, the BDC 220 determines whether the vehicle user is approaching the vehicle with a mobile device (e.g., a smart key) (S11). When the BDC 220 detects that the vehicle user is approaching the vehicle with the smart key ("Yes" in S11), the BDC 220 may send a wake-up signal to the AVNT 800, thereby switching the AVNT 800 from the sleep state to the wake-up state (S12).

[0057] After the AVNT 800 is awakened, the AVNT 800 controls the microphone 110 to start. When the vehicle user outputs voice information at a position close to the vehicle, the microphone 110 may receive the voice information output by the vehicle user and transmit the voice information to the AVNT 800 (S13).

[0058] The AVNT 800 performs ECNR on the sound information received from the microphone 110 (S14). Furthermore, the AVNT 800 compares the voiceprint of the ECNR-processed sound information with the voiceprints pre-stored in the AVNT 800 to determine whether the voiceprint of the sound information received from the microphone 110 is one of the pre-stored voiceprints (S15). If the voiceprint of the sound information received from the microphone 110 is one of the pre-stored voiceprints ("Yes" in S15), the AVNT 800 recognizes the sound information received from the microphone 110 (S16).

[0059] After the AVNT CPU 820 recognizes the sound information, the AVNT 800 can determine whether the sound information is valid (S17). When the AVNT 800 determines that the sound information is valid ("Yes" in S17), the AVNT 800 can output a control instruction to the corresponding target in-vehicle device 600 (specifically, the vehicle ECU) based on the recognition result (S18).

[0060] The vehicle ECU operates according to the received control command (S19). In addition, the vehicle ECU may send the control result to the AVNT 800, and the AVNT 800 may control the speaker 710 to output audio to prompt the vehicle user about the control result of the target vehicle-mounted device (S20).

[0061] By utilizing the device and method for controlling a vehicle from outside the vehicle according to an embodiment of the present invention, the application scope of voice recognition (VR) technology can be expanded, so that VR technology can be used not only inside the vehicle but also outside the vehicle, thereby increasing the convenience of operation.

[0062] In addition, the device and method for controlling a vehicle from outside the vehicle according to an embodiment of the present invention provide safety guarantees for VR technology, that is, only after the first safety condition and the second safety condition are met, can the on-board equipment be controlled by sound information from outside the vehicle, thereby ensuring the safety of the vehicle.

[0063] Furthermore, the apparatus and method for controlling a vehicle from outside the vehicle according to an embodiment of the present invention reuse the existing VESS speakers and the existing AVNT, and improve the control logic of the AVNT CPU so that the AVNT CPU performs ECNR processing, voiceprint comparison, and voice recognition. Therefore, compared with existing vehicle components, only a microphone is added, and the cost of the additional materials is limited, thereby achieving the goal of not increasing additional costs.

[0064] The various embodiments of the invention are not an exhaustive list of all possible combinations, but are intended to describe representative aspects of the invention, and what is described in terms of various embodiments can be applied independently or in combinations of two or more.
