[0045] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0046] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0047] The main solution of the present application is: when it is monitored that the distance between the vehicle and the mobile phone is less than the preset interaction distance, an ultra-wideband communication connection is established with the vehicle; an ultra-wideband positioning signal sent by the vehicle is received, and the positioning distance between the vehicle and the mobile phone is determined based on the ultra-wideband positioning signal; in response to a vehicle control instruction triggered based on the positioning distance, the vehicle control instruction is converted into an ultra-wideband control signal and sent to the vehicle, so as to control the vehicle to perform the operation indicated by the vehicle control instruction.

[0048] At present, the remote interaction functions such as wireless positioning and remote unlocking of vehicles are usually realized by using Bluetooth technology. Specifically, users can locate and control vehicles through interactive devices connected to the vehicle's Bluetooth. However, since the maximum distance of Bluetooth wireless transmission is usually limited to 10 to 20 meters, this means that the method of remotely interacting with vehicles using Bluetooth technology requires that the distance between the interactive device and the vehicle to be interacted does not exceed the maximum distance of Bluetooth wireless transmission, otherwise the Bluetooth connection will be interrupted, resulting in the user being unable to continue to locate and control the vehicle. In other words, the method of remotely interacting with vehicles using Bluetooth technology has the problem of a small interactive range and low interaction efficiency.

[0049] When the present application detects that the distance between the headset and the vehicle is less than the preset interaction distance, it automatically establishes a communication connection between the headset and the vehicle based on the ultra-wideband technology, then receives the ultra-wideband positioning signal sent by the vehicle, determines the distance between the headset and the vehicle based on the ultra-wideband positioning signal, and responds to the vehicle control command triggered based on the distance, converts the vehicle control command into an ultra-wideband control signal and sends it to the vehicle to control the vehicle to perform the operation indicated by the ultra-wideband control command. In this way, since the positioning distance of the ultra-wideband technology is far from the positioning distance of the Bluetooth technology, the present application expands the interactive range of remote interaction with the vehicle, realizes the positioning and control of the vehicle within a larger interactive range, and thus improves the interaction efficiency.

[0050] It should be noted that the execution subject of the method in each embodiment of the vehicle control method of the present application may be a headset. The present embodiment and the following embodiments are described below with the headset as the execution subject.

[0051] Based on this, the present application proposes a vehicle control method of the first embodiment, please refer to Figure 1 , the vehicle control method comprises steps S10 to S30:

[0052] Step S10, when it is detected that the distance between the vehicle and the mobile terminal is less than a preset interaction distance, establishing an ultra-wideband communication connection with the vehicle;

[0053] It should be noted that the vehicle control method of the present application is applied to headphones, which are wearable voice interaction devices. In this embodiment, the headphones can be OWS (Open Wearable Stereo) headphones, and the embodiments of the present application do not limit the above headphones to left headphones or right headphones. Generally speaking, users use a pair of headphones. The positioning distance of ultra-wideband (Ultra-Wideband) technology refers to the maximum distance at which UWB signals can be effectively transmitted and successfully decoded by the receiving end for positioning. The positioning distance of ultra-wideband technology is a preset interaction distance, usually 150 meters to 200 meters.

[0054] When it is detected that the distance between the headset and the vehicle is less than the preset interaction distance, an ultra-wideband communication connection with the vehicle is established, that is, data transmission between the headset and the vehicle can be achieved based on UWB technology.

[0055] In this embodiment, the headset includes an ultra-wideband module, the vehicle includes an ultra-wideband base station, and step S10 may include:

[0056] Step S101 , when it is detected that the distance between the vehicle and the vehicle is less than a preset interaction distance, an ultra-wideband communication connection is established between the ultra-wideband module and the ultra-wideband base station.

[0057] It should be noted that an ultra-wideband module, namely, a UWB module, is provided in the headset, and an ultra-wideband base station, namely, a UWB base station, is installed in the vehicle.

[0058] When the distance between the headset and the vehicle is less than a preset interaction distance, a communication connection between the ultra-wideband and the ultra-wideband base station is established.

[0059] In one feasible implementation, the presence of an ultra-wideband base station is sensed by an ultra-wideband module. When the ultra-wideband module is able to sense the ultra-wideband base station, it indicates that the distance between the ultra-wideband module and the ultra-wideband base station is less than a preset interaction distance, that is, it is considered that the distance between the headset and the vehicle is less than the preset interaction distance. When the ultra-wideband base station is sensed by the ultra-wideband module, a communication connection request (hereinafter referred to as a first connection request for distinction) is sent to the ultra-wideband base station. After receiving the first connection request, the ultra-wideband base station responds to the first connection request to complete the handshake process and establish an ultra-wideband communication connection between the headset and the vehicle.

[0060] In another feasible implementation, the presence of the ultra-wideband module is sensed by an ultra-wideband base station. When the ultra-wideband base station is able to sense the ultra-wideband module, it indicates that the distance between the ultra-wideband module and the ultra-wideband base station is less than the preset interaction distance, that is, it is considered that the distance between the headset and the vehicle is less than the preset interaction distance, and the ultra-wideband base station sends a communication connection request (hereinafter referred to as the second connection request for distinction) to the ultra-wideband module when sensing the ultra-wideband module. After receiving the second connection request, the ultra-wideband module responds to the second connection request to complete the handshake process and establish an ultra-wideband communication connection between the headset and the vehicle.

[0061] Step S20, receiving an ultra-wideband positioning signal sent by the vehicle, and determining a positioning distance to the vehicle based on the ultra-wideband positioning signal;

[0062] It should be noted that after the ultra-wideband communication connection between the headset and the vehicle is established, the vehicle actively sends real-time positioning information (i.e. the above-mentioned ultra-wideband positioning signal) to the headset, wherein the ultra-wideband positioning signal represents the real-time distance between the headset and the vehicle (i.e. the above-mentioned positioning distance), and the data format of the ultra-wideband positioning signal is the UWB signal format.

[0063] An ultra-wideband positioning signal sent by the vehicle is received, and a positioning distance between the headset and the vehicle is determined based on the ultra-wideband positioning signal.

[0064] In a specific implementation, the ultra-wideband module includes an ultra-wideband transceiver unit and an ultra-wideband encryption unit, and the step S20 may include:

[0065] Step S201, receiving an ultra-wideband positioning signal sent by the ultra-wideband base station through the ultra-wideband transceiver unit, and performing ultra-wideband demodulation processing on the ultra-wideband positioning signal to obtain a first digital signal;

[0066] Step S202: Decrypting the first digital signal by the ultra-wideband encryption unit based on a preset decryption key to obtain a positioning distance to the vehicle.

[0067] It should be noted that the ultra-wideband module of the headset includes an ultra-wideband transceiver unit (i.e., UWB transceiver circuit) and an ultra-wideband encryption unit (i.e., UWB encryption circuit). Among them, the UWB transceiver circuit is used to receive UWB signals and demodulate the UWB signals to obtain digital signals; encryption keys and decryption keys for UWB data transmission between the headset and the vehicle are pre-set, and the UWB encryption circuit is used to decrypt the digital signal demodulated by the UWB transceiver circuit based on the preset decryption key. Among them, for security reasons, the UWB transceiver circuit must be accompanied by a UWB encryption circuit, which is a necessary part of the electronic device that functions as a car key, and is used to ensure data security and key management.

[0068] The ultra-wideband positioning signal sent by the ultra-wideband base station of the vehicle is received by the ultra-wideband transceiver unit, and the ultra-wideband positioning signal is ultra-wideband demodulated to obtain a digital signal (hereinafter referred to as the first digital signal for distinction), and then the first digital signal is decrypted by the ultra-wideband encryption unit based on a preset decryption key to obtain the positioning distance between the headset and the vehicle.

[0069] For example, Figure 2 The figure shows a schematic diagram of the vehicle control architecture. A UWB module is provided in the headset, and the UWB module includes a UWB transceiver circuit, a UWB encryption circuit and a UWB antenna. A UWB base station is provided in the vehicle to be interacted with, and the UWB base station also includes a UWB antenna. The UWB antennas of the headset and the vehicle are used for data transmission.

[0070] Step S30, in response to the vehicle control instruction triggered based on the positioning distance, convert the vehicle control instruction into an ultra-wideband control signal and send it to the vehicle to control the vehicle to perform the operation indicated by the vehicle control instruction.

[0071] It should be noted that after receiving the vehicle control instruction, the system responds to the vehicle control instruction and converts the vehicle control instruction into a UWB signal and sends it to the vehicle so that the vehicle can perform corresponding operations based on the UWB signal. The vehicle control instructions include but are not limited to: "Open the main car door", "Start preheating", "Unlock the door", "Turn on the vehicle air conditioner", etc.

[0072] In response to a vehicle control instruction triggered based on the positioning distance between the headset and the vehicle, the vehicle control instruction is converted into an ultra-wideband signal (hereinafter referred to as the ultra-wideband control signal for distinction), and the ultra-wideband control signal is sent to the vehicle, so that after receiving the ultra-wideband control signal, the vehicle responds to the vehicle control instruction represented in the ultra-wideband control signal and executes the operation indicated by the vehicle control instruction.

[0073] It is worth emphasizing that the power consumption of the UWB system is not large, and it can exist in headphones and cars. The current of UWB working once is generally around 150mA, and the current pulse lasts about 340us. The current pulse during operation is short, consuming only 0.0125mAh at a time. Generally, it can be set to query once every 0.5s to 2s, which consumes less power. The battery capacity of the car itself is much larger than that of the headphones, so even if the UWB base station on the car is always on, it will basically not affect the battery capacity of the car itself. Secondly, the UWB positioning distance is at the centimeter level, which is obviously enough for car positioning, and the total clearance area of ​​the evaluation UWB circuit, encryption circuit and UWB antenna is about 60 square millimeters, which is enough to be placed in OWS. Therefore, setting a UWB module in the headset will not increase the volume and power consumption of the headset part too much, and has the advantages of small size and low power consumption.

[0074] When the embodiment of the present application detects that the distance between the headset and the vehicle is less than the preset interaction distance, the embodiment of the present application automatically establishes a communication connection between the headset and the vehicle based on the ultra-wideband technology, then receives the ultra-wideband positioning signal sent by the vehicle, determines the distance between the headset and the vehicle based on the ultra-wideband positioning signal, and responds to the vehicle control command triggered based on the distance, converts the vehicle control command into an ultra-wideband control signal and sends it to the vehicle to control the vehicle to perform the operation indicated by the ultra-wideband control command. In this way, since the positioning distance of the ultra-wideband technology is far from the positioning distance of the Bluetooth technology, the embodiment of the present application expands the interactive range of remote interaction with the vehicle, realizes the positioning and control of the vehicle within a larger interactive range, and thus improves the interaction efficiency.

[0075] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. On this basis, the earphone also includes a speaker, and after the step S20, the vehicle control method also includes:

[0076] Step A10: convert the positioning distance into a first voice signal, and play the first voice signal through the speaker.

[0077] It should be noted that the earphone includes a speaker for playing voice signals.

[0078] After the headset receives the ultra-wideband positioning signal sent by the vehicle and determines the positioning distance based on the ultra-wideband positioning signal, the headset can convert the positioning distance into a corresponding voice signal (hereinafter referred to as the first voice signal for distinction), and then play the first voice signal through the speaker of the headset to inform the user of the real-time distance between the headset and the vehicle (i.e., the above-mentioned positioning distance).

[0079] In this way, UWB technology is widely used in positioning and communication functions. It has the advantages of small size, high positioning accuracy (centimeter level), long positioning distance (about 150m), and low power consumption. OWS headphones, as a frequently worn voice interaction device, can be combined with UWB technology to realize real-time positioning and voice broadcast of positioning distance to enhance user experience.

[0080] In a feasible implementation manner, the vehicle control instruction includes a first control instruction, and the step S30 may include:

[0081] Step S301, when it is detected that the positioning distance is less than a preset control distance, the first control instruction is automatically triggered;

[0082] Step S302: In response to the first control instruction, convert the first control instruction into an ultra-wideband control signal and send it to the vehicle to control the vehicle to perform the operation indicated by the first control instruction.

[0083] It should be noted that the embodiment of the present application is pre-set with a condition for automatically triggering a specific control command, which can be that when the positioning distance between the headset and the vehicle is less than 15 meters, the vehicle control command of "opening the main driving door" is automatically triggered. Among them, the embodiment of the present application does not limit the specific size of the preset control distance, and the preset control distance can be any length that meets the personalized needs of the user.

[0084] The positioning distance between the headset and the vehicle is determined in real time, and the positioning distance is monitored to see if it is less than the preset control distance. When the positioning distance is detected to be less than the preset control distance, a control instruction (hereinafter referred to as the first control instruction for distinction) is automatically triggered, and then the headset responds to the first control instruction, converts the first control instruction into an ultra-wideband control signal and sends it to the vehicle to control the vehicle to perform the operation indicated by the first control instruction. It should be understood that the first control instruction is an automatically triggered vehicle control instruction.

[0085] In another feasible implementation manner, the vehicle control instruction includes a second control instruction, and the step S30 may include:

[0086] Step S303, recording a second voice signal sent by the user based on the positioning distance through the microphone, and identifying a second control instruction in the second voice signal;

[0087] Step S304: In response to the second control instruction, convert the second control instruction into an ultra-wideband control signal and send it to the vehicle to control the vehicle to perform the operation indicated by the second control instruction.

[0088] It should be noted that the headset in this application is an OWS headset, and the OWS headset can run a simple AI voice recognition algorithm, and can perform voice recognition of simple texts such as "open the main driving door", "start preheating", "unlock the door", "turn on the vehicle air conditioner", etc. Therefore, when the user knows that the positioning distance between the headset and the vehicle is small, a voice command can be issued so that the OWS headset can transmit the vehicle control command in the form of a UWB signal to the vehicle after recognizing the vehicle control command in the voice signal issued by the user, so as to control the vehicle to perform the operation indicated by the vehicle control command.

[0089] When the user knows that the positioning distance between the headset and the vehicle is small and can control the vehicle to perform related operations under safe conditions, the user issues a voice control command. At this time, the headset receives the voice signal (hereinafter referred to as the second voice signal for distinction) issued by the user based on the positioning distance through the microphone, and then identifies the vehicle control command (hereinafter referred to as the second control command for distinction) in the second voice signal. After identifying the second control command, in response to the second control command, the second control command is converted into an ultra-wideband control signal and sent to the vehicle to control the vehicle to perform the operation indicated by the second control command. It should be understood that the second control command is a vehicle control command triggered by the user through voice.

[0090] Exemplarily, after receiving the UWB signal, the vehicle performs ultra-wideband demodulation processing on the UWB signal to obtain an encrypted digital signal, and then decrypts the encrypted digital signal based on a preset decryption key to obtain a vehicle control instruction whose original data is "start preheating". The vehicle responds to the vehicle control instruction, automatically wakes up the vehicle main control, and executes the vehicle preheating operation.

[0091] In this way, the embodiment of the present application adds a UWB module to the OWS headset and installs a UWB base station in the vehicle, including a UWB circuit, an encryption circuit, and a UWB antenna), and installs a UWB base station in the car, so that real-time positioning of the car in the parking lot can be achieved, and the real-time positioning distance can be broadcast to the user by OWS through voice broadcast. When the user is within a certain distance from the car, the vehicle can be awakened in advance to start the preheating function, and then automatically unlocked or preheated and unlocked by recognizing voice commands. This can greatly improve the user experience of OWS users and make it easier and more convenient to find and start the car in the parking lot.

[0092] In this embodiment, the ultra-wideband module further includes an ultra-wideband antenna, and step S30 may include:

[0093] Step B10, encrypting the vehicle control instruction based on a preset encryption key by the ultra-wideband encryption unit to obtain an encrypted second digital signal;

[0094] Step B20, performing ultra-wideband modulation processing on the second digital signal through the ultra-wideband transceiver unit to obtain an ultra-wideband control signal;

[0095] Step B30: sending the ultra-wideband control signal to the vehicle via the ultra-wideband antenna.

[0096] It should be noted that the ultra-wideband module in the headset also includes an ultra-wideband antenna for signal transmission and reception.

[0097] The vehicle control instruction to be sent is encrypted by the ultra-wideband encryption unit based on a preset encryption key to obtain an encrypted digital signal (hereinafter referred to as the second digital signal for distinction), and then the second digital signal is ultra-wideband modulated by the ultra-wideband transceiver unit to obtain a signal in UWB form, that is, the above-mentioned ultra-wideband control signal. Finally, the ultra-wideband control signal is sent to the vehicle through the ultra-wideband antenna. The vehicle receives the ultra-wideband control signal through the UWB antenna of the ultra-wideband base station and executes the operation indicated by the vehicle control instruction.

[0098] For example, Figure 3 The figure shows a schematic diagram of a vehicle control process, in which the headset first monitors the distance between the headset and the vehicle, and determines whether the distance between the headset and the vehicle is less than a preset interaction distance; when the distance between the headset and the vehicle is less than the preset interaction distance, the headset actively sends a connection request; after receiving the connection request, the vehicle responds to the connection request and establishes a UWB connection between the headset and the vehicle; after the headset and the vehicle establish a communication connection, an ultra-wideband positioning signal is sent by an ultra-wideband base station of the vehicle; after receiving the ultra-wideband positioning signal, the headset determines the positioning distance between the headset and the vehicle; in response to a vehicle control instruction automatically triggered or manually triggered based on the positioning distance, the vehicle control instruction is converted into a UWB signal and sent to the vehicle; the vehicle responds to the received UWB signal and the vehicle control instruction represented in the UWB signal, and executes the operation indicated by the vehicle control instruction.

[0099] In this way, the embodiment of the present application broadcasts the real-time distance between the user and the vehicle to the user through headphones so that the user can understand the relative position information between the user and the vehicle, and is provided with an automatic trigger mechanism and a manual trigger mechanism for vehicle control instructions to control the vehicle to open the door or preheat when the distance between the user and the vehicle is close, thereby realizing remote interaction with the vehicle and improving vehicle interaction efficiency.

[0100] The present application also provides a vehicle control device, please refer to Figure 4 , the vehicle control device is applied to headphones, and the vehicle control device comprises:

[0101] A connection module 10, configured to establish an ultra-wideband communication connection with the vehicle when it is detected that the distance between the vehicle and the vehicle is less than a preset interaction distance;

[0102] A positioning module 20, configured to receive an ultra-wideband positioning signal sent by the vehicle, and determine a positioning distance to the vehicle based on the ultra-wideband positioning signal;

[0103] The control module 30 is used to respond to the vehicle control instruction triggered based on the positioning distance, convert the vehicle control instruction into an ultra-wideband control signal and send it to the vehicle, so as to control the vehicle to perform the operation indicated by the vehicle control instruction.

[0104] Optionally, the headset includes an ultra-wideband module, the vehicle includes an ultra-wideband base station, and the connection module 10 is further used for:
