Description

Technical Field

[0001] This invention relates to the field of unmanned vehicle interception technology, and in particular to an unmanned vehicle interception system. Background Technology

[0002] With societal progress, self-driving cars have gradually become the development direction of major automakers and the goal pursued by major consumers. With the increasingly mature self-driving car technology of major automakers, many self-driving cars will inevitably appear on the roads in the near future, but some problems will arise as a result.

[0003] Self-driving cars can travel long distances to their destinations without human intervention. However, when law enforcement officers temporarily set up roadblocks to intercept vehicles and conduct security checks, they are unable to effectively stop the self-driving cars or unlock and inspect the items carried on them, thus creating security risks. Furthermore, the self-driving cars cannot verify the legitimacy of the inspectors, making it impossible to ensure the safety of the self-driving cars' journeys.

[0004] Currently, only the car owner can unlock the self-driving car using the car key or an application on a mobile device. Furthermore, when the owner is not in the car, law enforcement officers at checkpoints cannot intercept and unlock the self-driving car for inspection. Summary of the Invention

[0005] This invention provides an unmanned vehicle interception system that solves the current problem that law enforcement officers are unable to intercept and inspect unmanned vehicles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An unmanned vehicle interception system includes an interception device for intercepting unmanned vehicles traveling on the road. The device includes a processing module, a signal transmitting module, a switching component, a storage module, and a power supply component. The processing module is responsible for processing various received signals and issuing corresponding instructions. The signal transmitting module is electrically connected to the processing module and is responsible for transmitting signals.

[0008] The switching assembly and the processing module are electrically connected. The switching assembly is used to send signals to control the processing module, which in turn sends control signals to control the autonomous vehicle. The switching assembly includes an interception unit, a door unlocking unit, and a reset unit. The interception unit is used to send an interception signal to stop the autonomous vehicle in a safe position. The door unlocking unit is used to send a door unlocking signal to unlock the doors of the autonomous vehicle, making it easier for law enforcement officers to check whether there are any illegal or dangerous items inside the vehicle. The reset unit is used to send a reset signal so that the autonomous vehicle can continue its previous driving path after the inspection is completed and no problems are found.

[0009] The storage module is electrically connected to the processing module and is used to store information about law enforcement personnel using the interception device. The relevant information of the law enforcement personnel needs to be entered in advance.

[0010] The power supply module is electrically connected to the processing module, signal transmission module, switching components, and storage module to provide power to each module and ensure that each module can operate normally.

[0011] The interception device is operated by law enforcement officers. When setting up checkpoints in temporary areas, it can be used to intercept and inspect driverless cars. The switch assembly has multiple units that can remotely control driverless cars according to the actual situation. It can conduct a comprehensive inspection of driverless cars to prevent them from driving dangerously or carrying illegal or dangerous items.

[0012] The interception system also includes an autonomous vehicle, which receives signals from the interception device and performs corresponding operations. The autonomous vehicle includes a main control module, a signal receiving module, control components, and door locks.

[0013] The main control module is used to process various received signals and issue corresponding instructions; the signal receiving module is electrically connected to the main control module and is used to receive signals sent by the signal transmitting module on the interception device.

[0014] The control component, electrically connected to the main control module, is used to receive instructions from the main control module and control the autonomous vehicle to perform corresponding operations according to the instructions.

[0015] The door lock is electrically connected to the main control module and is used to receive commands from the main control module and control the opening and closing of the doors of the autonomous vehicle according to the commands.

[0016] The autonomous vehicle responds to the signals emitted by the interception device and controls the vehicle to operate accordingly, so as to facilitate law enforcement officers to inspect the autonomous vehicle. This allows law enforcement officers to easily intercept and inspect the autonomous vehicle during law enforcement operations.

[0017] Furthermore, the interception unit sends an interception signal through the processing module to generate an interception radio signal encrypted in the first encryption method. The signal transmitting module transmits the interception radio signal to at least one driving unmanned vehicle within the first preset distance range of the interception device, so that the signal receiving module in the unmanned vehicle receives the interception radio signal and sends the radio signal to the main control module for decryption. After decryption, the main control module controls the unmanned vehicle to stop.

[0018] The door unlocking unit sends a door unlocking signal through the processing module, generates a door unlocking radio signal encrypted with a second encryption method, and the signal transmitting module transmits the door unlocking radio signal to at least one stopped autonomous vehicle within the second preset distance range of the interception device, so that the signal receiving module in the autonomous vehicle receives the door unlocking radio signal and sends the radio signal to the main control module for decryption. After decryption, the main control module controls the autonomous vehicle to open the door.

[0019] The reset unit sends a reset signal through the processing module, generating a reset radio signal encrypted with a third encryption method. The signal transmitting module transmits the reset radio signal to at least one stopped autonomous vehicle within the third preset distance range of the interception device, so that the signal receiving module in the autonomous vehicle receives the reset radio signal and sends the radio signal to the main control module for decryption. After decryption, the main control module controls the autonomous vehicle to continue driving.

[0020] Furthermore, the storage module is used to store information about law enforcement officers, facilitating the management of law enforcement personnel and ensuring that the interception device is used by designated personnel.

[0021] Furthermore, the storage module is also used to store interception information for each intercepted autonomous vehicle. The interception information includes at least one of the following: vehicle stopping time, vehicle stopping location, door opening time, vehicle reset time, and violation information, which facilitates subsequent inspection and review of law enforcement records.

[0022] Furthermore, the interception device also includes a wireless communication module, which is electrically connected to both the processing module and the storage module. The wireless communication module is used to upload information received from law enforcement personnel and interception information from the storage module to the backend server. The backend server communicates with the mobile terminal of the owner of each intercepted autonomous vehicle. The interception device sends the interception process and information about the intercepted autonomous vehicles to the backend server for monitoring. Simultaneously, the backend server also notifies the owners of the autonomous vehicles to prevent disputes.

[0023] Furthermore, the control component includes a steering mechanism, an acceleration mechanism, a braking mechanism, and a gear shifting mechanism. The steering mechanism is used to control the steering of the autonomous vehicle, the acceleration mechanism is used to control the acceleration of the autonomous vehicle, the braking mechanism is used to control the braking of the autonomous vehicle, and the gear shifting mechanism is used to control the gear switching of the autonomous vehicle. All mechanisms in the control component are controlled by the main control module.

[0024] Furthermore, autonomous vehicles also include a human-machine interaction unit, which is mainly suitable for law enforcement scenarios without interception devices. The human-machine interaction unit includes a law enforcement detection module, a voice transmission module, a document recognition module, and an interaction activation module.

[0025] The law enforcement detection module is used to receive law enforcement officers' hand gestures or actions, identify them, and generate corresponding signals; when encountering temporary checks on the road, it can identify law enforcement officers' hand gestures and accept inspection.

[0026] The voice transmission module is used to send voice data to prompt law enforcement officers to present their identification for law enforcement purposes. It issues a prompt, indicating to law enforcement officers that they must present valid law enforcement credentials.

[0027] The document recognition module receives relevant data from law enforcement documents and determines their legality based on this data. When law enforcement officers present their documents, the document recognition module identifies them.

[0028] The interactive activation system, if the documents are valid, will activate the intelligent voice interaction system of the autonomous vehicle, enabling the autonomous vehicle to interact with law enforcement officers and cooperate with them to inspect the vehicle.

[0029] Furthermore, the human-computer interaction unit also includes an image acquisition module, a vehicle communication module, and a warning transmission module. The image acquisition module is used to collect image data of law enforcement officers and compare it with relevant data on their law enforcement credentials.

[0030] The vehicle communication module is used to send or receive wireless signals. It can receive signals from interception devices or send signals to notify the owner of the autonomous vehicle.

[0031] The warning sending module, when the document recognition module detects an invalid document, sends an alarm request and / or the collected image data of the law enforcement personnel to the cloud platform via the vehicle communication module, and waits for the cloud platform to return an instruction. When illegal interception occurs, the warning sending module sends a signal, which controls the vehicle communication module to send an illegal interception message to the cloud platform, and waits for a response signal from the cloud platform.

[0032] Furthermore, the human-computer interaction unit also includes a voice receiving module and an information display module. The voice receiving module is used to receive voice data from law enforcement officers, including prompts to the autonomous vehicle to provide information indicating that it is driving legally.

[0033] The information display module sends information indicating legal driving in image data format to the display device for easy viewing by law enforcement officers.

[0034] Furthermore, the display device includes any one of the following: an in-vehicle display device for an autonomous vehicle, a windshield, a driver's side window, or a navigation display device. Attached Figure Description

[0039] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0044] With societal progress, self-driving cars have gradually become the development direction of major automakers and the goal pursued by major consumers. With the increasingly mature self-driving car technology of major automakers, many self-driving cars will inevitably appear on the roads in the near future, but some problems will arise as a result.

[0045] Self-driving cars can travel long distances to their destinations without human intervention. However, when law enforcement officers temporarily set up roadblocks to intercept vehicles and conduct security checks, they are unable to effectively stop the self-driving cars or unlock and inspect the items carried on them, thus creating security risks. Furthermore, the self-driving cars cannot verify the legitimacy of the inspectors, making it impossible to ensure the safety of the self-driving cars' journeys.

[0046] Furthermore, self-driving cars cannot recognize the hand gestures of law enforcement officers. In emergency situations, self-driving cars cannot drive according to the gestures of law enforcement officers, which can easily lead to congestion and is detrimental to road safety.

[0047] Currently, only the car owner can unlock the self-driving car using the car key or an application on a mobile device. Furthermore, when the owner is not in the car, law enforcement officers at checkpoints cannot intercept and unlock the self-driving car for inspection.

[0048] To address the aforementioned problems, this invention provides an unmanned vehicle interception system. By incorporating an interception device and a human-machine interaction unit, it provides real-time feedback for different law enforcement scenarios, ensuring that unmanned vehicles can be inspected and drive safely based on the gestures of law enforcement officers. The embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0049] like Figure 1 As shown, an unmanned vehicle interception system includes an interception device and an unmanned vehicle. The interception device is used to temporarily intercept unmanned vehicles traveling on the road, and the unmanned vehicle performs corresponding operations after receiving a signal from the interception device.

[0050] The interception device is for the exclusive use of law enforcement officers conducting checkpoint inspections. The interception device includes a processing module, a signal transmitting module, a switching component, a storage module, and a power supply module. The processing module is a central processing unit, which is connected to the signal transmitting module, the switching component, the storage module, and the power supply module. The central processing unit can receive signals sent by each module and component, and can also send signals to each module and component.

[0051] The switching assembly is used to send corresponding control signals. The control processing module sends control signals to facilitate the autonomous vehicle to receive signals and perform corresponding operations. The switching assembly includes an interception unit, a door unlocking unit, and a reset unit. The interception unit sends an interception signal, the door unlocking unit sends a door unlocking signal, and the reset unit sends a reset signal.

[0052] The interception unit, door unlocking unit, and reset unit in the switch assembly all require manual operation by law enforcement personnel to send signals.

[0053] The intercept signal causes the autonomous vehicle to stop in a safe location; the door unlock signal causes the autonomous vehicle to unlock its doors, facilitating law enforcement officers to inspect the vehicle for any illegal or dangerous items; the reset signal allows the autonomous vehicle to continue its previous route after completing its inspection and finding no problems.

[0054] In some embodiments of this application, the switch assembly is not limited to the above-mentioned units, but may also include other switches such as power on / off buttons and information transmission units, and can be adjusted accordingly based on the actual situation.

[0055] The storage module is used to store the law enforcement personnel information of the interception device. The interception device needs to pre-enter the relevant information of the law enforcement personnel, which is stored by the storage module to facilitate the management of law enforcement personnel and ensure that the interception device is used by dedicated personnel.

[0056] The power supply module is electrically connected to the processing module, signal transmission module, switching components, and storage module, respectively, to supply power to each module and ensure that each module can operate normally.

[0057] Autonomous vehicles include a main control module, a signal receiving module, control components, and door locks.

[0058] The main control module is used to process various received signals and issue corresponding instructions.

[0059] The signal receiving module and the main control module are electrically connected. The receiving module receives the signal emitted by the signal transmitting module on the interception device and sends the signal to the main control module. The main control module outputs corresponding control commands based on the signal from the interception device.

[0060] The control component is electrically connected to the main control module and is used to receive instructions from the main control module and control the autonomous vehicle to perform corresponding operations according to the instructions.

[0061] The door lock is electrically connected to the main control module and is used to receive instructions from the main control module and control the opening and closing of the doors of the autonomous vehicle according to the instructions.

[0062] When law enforcement officers press the button on the interception unit, the interception unit triggers an interception signal and sends the interception signal to the processing module. When the interception signal is triggered, the processing module generates an intercepted radio signal encrypted using a first encryption method and sends it to the signal transmission module.

[0063] The signal transmitting module transmits the intercepted radio signal to at least one autonomous vehicle in motion within a first preset distance range of the interception device, so that the signal receiving module in the autonomous vehicle receives the intercepted radio signal and sends the radio signal to the main control module for decryption. After decryption, the main control module issues a signal to control the control component.

[0064] The control component controls the vehicle's movement and includes a steering mechanism, an acceleration mechanism, a braking mechanism, and a gear shifting mechanism. After receiving a vehicle stop signal, the control component controls the steering mechanism, braking mechanism, throttle mechanism, and gear shifting mechanism to decelerate the driverless vehicle and bring it to a stop at the side of the road. Then, it shifts the gear to the parking gear.

[0065] In this embodiment, considering that the braking distance of a vehicle at a speed of 100 km / h is about 40 meters, and that an excessively long distance range may intercept too many vehicles, leading to traffic congestion, the first preset distance range is set to 10m to 80m. That is, law enforcement officers only intercept driverless cars within a range of 10m to 80m ahead. The first preset distance range can be set by adjusting the signal frequency of the intercepted radio signal, but it is not limited to this distance range. It can be adjusted according to the actual situation and different scenarios.

[0066] When a driverless car is intercepted and brought to a complete stop, law enforcement officers press the door unlocking unit on the vehicle. At this time, the door unlocking unit is used to trigger the door unlocking signal and send the door unlocking signal to the processing module. When the door unlocking signal is triggered, the processing module generates a door unlocking radio signal encrypted with a second encryption method.

[0067] The signal transmitting module transmits the door unlocking radio signal to at least one stopped autonomous vehicle within the second preset distance range of the interception device, so that the signal receiving module in the autonomous vehicle receives the door unlocking radio signal and sends the radio signal to the main control module for decryption. After decryption, the main control module controls the door lock of the autonomous vehicle to unlock the door.

[0068] At this point, law enforcement officers can open the door and board the vehicle to inspect it and confirm whether there are any prohibited items inside.

[0069] After confirmation, law enforcement officers press the reset unit button on the driverless car. At this time, the reset unit is used to trigger a reset signal and send the reset signal to the processing module 11. When the reset signal is triggered, the processing module generates a reset radio signal encrypted with a third encryption method.

[0070] The signal transmitting module transmits a reset radio signal to at least one stopped autonomous vehicle within a third preset distance range of the interception device, so that the signal receiving module in the autonomous vehicle receives the reset radio signal and sends the radio signal to the main control module for decryption. After decryption, the main control module sends a signal to control the control component, which then controls the vehicle to continue driving.

[0071] After receiving the reset signal, the signal receiving module of the autonomous vehicle controls the door lock to close the door of the autonomous vehicle.

[0072] Upon receiving the reset signal, the vehicle is controlled to continue driving.

[0073] In this embodiment, the second preset distance range is set to 0-10m, and the third preset distance range is set to 0-10m. That is, law enforcement officers only unlock or reset the driverless car within 10m in front of them to prevent unlocking the vehicle while it is in motion. The second and third preset distance ranges can be set by adjusting the signal frequency of the radio signal, but they are not limited to these distance ranges. They can be adjusted according to the actual situation.

[0074] In this embodiment, the radio signals emitted by the interception device of the autonomous vehicle are all authenticated and encrypted, and can only be received and recognized by the signal receiving module of the autonomous vehicle. The signal receiving module will not receive any other radio signals, thus improving the interception accuracy and enhancing system security.

[0075] The storage module is used to store interception information for each intercepted driverless car. The interception information includes at least one of the following: vehicle stopping time, vehicle stopping location, door opening time, vehicle resetting time, and violation information. This facilitates subsequent inspection and review of law enforcement records, ensures the traceability of the entire law enforcement process, and avoids disputes.

[0076] Furthermore, the interception device also includes a wireless communication module, which is electrically connected to both the processing module and the storage module. The wireless communication module is used to upload information received from law enforcement personnel and interception information from the storage module to the backend server. The backend server communicates with the mobile terminal of the owner of each intercepted autonomous vehicle. The interception device sends the interception process and information about the intercepted autonomous vehicles to the backend server for monitoring. Simultaneously, the backend server also notifies the owners of the autonomous vehicles.

[0077] The backend server integrates various information received from the wireless communication module and communicates with the mobile terminals of the owners of each intercepted driverless car, sending the corresponding information to the corresponding mobile terminals. This informs the car owners when and where the law enforcement officer with a specific employee number opened the car for inspection, whether there were any violations, and other information. The notification method can be any of SMS or application push notifications.

[0078] In this embodiment, the wireless communication module 15 includes at least one of a 2G module, a 3G module, a 4G module, a 5G module, a Bluetooth module, and a Wi-Fi module.

[0079] In this embodiment, various types of information can also be sent to the cloud platform through the communication module installed on the autonomous vehicle.

[0080] The driverless car interception system provided in this embodiment can assist law enforcement officers at public security checkpoints in conveniently intercepting driverless cars on public roads. Furthermore, this embodiment can also assist law enforcement officers in unlocking and opening the doors of the intercepted driverless cars to facilitate inspection, thereby effectively improving the work efficiency of law enforcement officers and combating illegal criminal activities involving the use of driverless cars to transport dangerous and prohibited items.

[0081] This embodiment also provides a method for intercepting an unmanned vehicle, which is implemented using the interception system described above.

[0082] like Figure 2 As shown, the interception method includes the following steps:

[0083] Step 11: The interception device triggers an interception signal to intercept the driverless car.

[0084] In this step, when law enforcement officers press the intercept switch, the intercept switch triggers an intercept signal and sends the intercept signal to the processing module. When the processing module triggers the intercept signal, it generates an intercepted radio signal encrypted using a first preset encryption method and sends it to the signal transmission module.

[0085] The signal transmitting module transmits intercepted radio signals to the signal receiving module of at least one autonomous vehicle in autonomous driving within a first preset distance range from the intercepting device. The intercepted radio signals are used to trigger the autonomous driving control module to stop the autonomous vehicle.

[0086] Step 12: The interception device triggers the door unlock signal, opening the door of the intercepted driverless car.

[0087] In this step, after an autonomous vehicle is intercepted and comes to a complete stop, law enforcement officers press the door unlock switch on the vehicle. At this time, the door unlock switch triggers the door unlock signal and sends the door unlock signal to the processing module. When the processing module triggers the door unlock signal, it generates a door unlock radio signal encrypted with a second preset encryption method and sends it to the signal transmission module.

[0088] The signal transmitting module transmits the door unlocking radio signal to the signal receiving module of at least one stopped driverless car within a second preset distance range from the interception device. The door unlocking radio signal is used to trigger the autonomous driving control module to open the door of the driverless car.

[0089] At this point, law enforcement officers can open the door and board the vehicle to inspect it and confirm whether there are any prohibited items inside.

[0090] Step 13: The interception device triggers a reset signal, and the intercepted driverless car resets and continues to drive.

[0091] In this step, after confirmation, law enforcement officers press the reset switch on the driverless car. At this time, the reset switch triggers a reset signal and sends the reset signal to the processing module. When the processing module triggers the reset signal, it generates a reset radio signal encrypted with a third preset encryption method and sends it to the signal transmission module.

[0092] The signal transmitting module transmits the reset radio signal to at least one stopped driverless car within a third preset distance range from the interceptor. The reset radio signal is used to trigger the autonomous driving control module to reset the driverless car and control the driverless car to continue driving.

[0093] Step 14: The interception device uploads various types of information to the backend server.

[0094] In this step, the storage module pre-stores information about law enforcement officers using the interception device. This information is used to identify the legitimate identity of the law enforcement officers equipped with the interception device, in order to prevent law enforcement officers from abusing their power.

[0095] The storage module also stores interception information for each intercepted driverless car, including at least one of the following: vehicle stopping time, vehicle stopping location, door opening time, vehicle reset time, and traffic violation information.

[0096] The wireless communication module will upload the law enforcement personnel information, the interception information and the license plate information received from the storage module to the backend server.

[0097] Step 15: The backend server integrates various types of information and sends them to the corresponding car owner's mobile terminal.

[0098] In this step, the backend server integrates various types of information received from the wireless communication module and communicates with the mobile terminal of the owner of each intercepted driverless car, sending the corresponding information to the corresponding mobile terminal. This informs the car owner when and where the law enforcement officer with a certain employee number opened the car for inspection, whether there were any violations, and other information. The notification method can be any of SMS or application push notifications.

[0099] Furthermore, such as Figure 3 As shown, the autonomous vehicle also includes a human-machine interaction unit, which is mainly suitable for law enforcement scenarios without interception devices. The human-machine interaction unit includes a law enforcement detection module, a voice transmission module, a document recognition module, and an interaction activation module.

[0100] The law enforcement detection module is used to receive law enforcement officers' hand gestures or actions, identify them, and generate corresponding signals; when encountering temporary checks on the road, it can identify law enforcement officers' hand gestures and accept inspection.

[0101] In this embodiment of the application, when a temporary checkpoint is set up on the driving path of the autonomous vehicle and law enforcement officers are not carrying interception devices, the vehicle is intercepted by law enforcement hand gestures. At this time, the law enforcement detection module determines whether law enforcement is being carried out by recognizing the uniform of the law enforcement officers. After the determination is completed, the law enforcement officers' law enforcement hand gestures are recognized, and it is determined whether the gestures are for temporary detours or parking on the side of the road. Then, the autonomous vehicle is controlled according to the recognized law enforcement hand gestures.

[0102] The voice transmission module is used to send voice data to prompt law enforcement officers to present their identification for law enforcement purposes. It issues a prompt, indicating to law enforcement officers that they must present valid law enforcement credentials.

[0103] After the self-driving car pulls over, it determines whether to send initial voice data based on a predetermined distance between itself and the law enforcement officer, or by motion recognition. The predetermined distance can be less than 20cm. Motion recognition can involve an image acquisition device capturing the initial voice data to prompt the officer to present their identification. The initial voice data can be a pre-stored standard voice snippet, such as "Please show your valid identification," or a user-preset voice snippet, such as "Please show your law enforcement certificate."

[0104] The document recognition module is divided into a document receiving module and a document judging module. It receives relevant data from law enforcement documents and judges the legality of the documents based on this data. When law enforcement officers present their documents, the document receiving module recognizes the documents, and then the document judging module determines their legality.

[0105] In this embodiment, after the autonomous vehicle sends the first voice data to the law enforcement officer, it waits for a preset time and then collects the relevant data of the document through the document receiving module. The document receiving module can be an image acquisition device or a voice device. For example, the image acquisition device can capture the image of the document, or the voice acquisition device can capture the document number spoken by the law enforcement officer. The information used to identify the legal identity of the law enforcement officer in the document can be extracted through image detection or voiceprint recognition technology. All of this information belongs to the relevant data of the document.

[0106] After acquiring the relevant data of the document, the data is transmitted to the document judgment module to determine the legality of the document. The main control module can also extract feature data from the relevant data, transmit the feature data to the cloud platform for authenticity verification, and feed back the authenticity verification result as the legality judgment result to the autonomous vehicle.

[0107] The cloud platform controls the autonomous vehicle's operations based on the results of its legality assessment. For example, if the documents are valid, the autonomous vehicle can move the windows towards the ground to open them, allowing audio data to be transmitted from inside the vehicle. If the documents are deemed invalid, indicating potential suspicion of the law enforcement personnel, the autonomous vehicle will send image data of the suspicious individuals to the cloud platform to enhance system security.

[0108] When the documents are deemed valid, the interactive activation module initiates the intelligent voice interaction system of the autonomous vehicle, enabling interaction between the autonomous vehicle and law enforcement personnel.

[0109] The intelligent voice interaction system can intelligently analyze the audio data collected from law enforcement officers. For example, when a law enforcement officer says "Please show your pass," the intelligent voice interaction system uses voice recognition technology to extract the keyword "pass" and sends it to the relevant main control module. The main control module then retrieves the image or audio data of the "pass" from the storage device and controls the presentation of the image or audio data to facilitate verification by law enforcement officers.

[0110] Furthermore, the human-computer interaction unit also includes an image acquisition module, a vehicle communication module, and a warning sending module.

[0111] The image acquisition module is used to collect image data of law enforcement officers and compare it with relevant data on their law enforcement credentials. The legality of the law enforcement credentials is determined through a dual check of the image and the credential number.

[0112] The vehicle communication module is used to send or receive wireless signals. It can receive signals from interception devices or send signals to notify the owner of the autonomous vehicle.

[0113] The warning sending module, when the document recognition module detects an invalid document, sends an alarm request and / or the collected image data of the law enforcement personnel to the cloud platform via the vehicle communication module, and waits for the cloud platform to return an instruction. When illegal interception occurs, the warning sending module sends a signal, which controls the vehicle communication module to send an illegal interception message to the cloud platform, and waits for a response signal from the cloud platform.

[0114] If the self-driving car determines that the documents are invalid, it will send an alarm request to the cloud platform. Alternatively, it may send image data of law enforcement personnel along with the alarm request for further verification of their identity. The self-driving car will wait for instructions from the cloud platform within a preset time frame and execute relevant operations accordingly. If the preset time frame is exceeded, the self-driving car will sound an alarm or flash its lights.

[0115] This application embodiment improves the safety of interaction between autonomous vehicles and law enforcement personnel by judging the identity of law enforcement personnel through autonomous vehicles, and solves the interaction problem between law enforcement personnel and autonomous vehicles through an intelligent voice interaction system.

[0116] Furthermore, embodiments of this application also provide a human-computer interaction method, the specific steps of which are as follows: Figure 4 As shown,

[0117] Step 21: Receive the first image data of law enforcement officers collected by the image acquisition device.

[0118] In this embodiment of the application, a problem arises in the interaction between the autonomous vehicle and law enforcement officers when the vehicle is warned by traffic police hand gestures for violating traffic rules and needs to stop for inspection. To solve this problem, the autonomous vehicle's image acquisition device collects image data of the law enforcement officers. The image data may include, for example, the image data of the law enforcement officers, and the target area may be, for example, the hand gestures of the law enforcement officers.

[0119] Optionally, in step 22, the hand gestures of law enforcement officers are detected based on image data.

[0120] Detecting hand gestures of law enforcement officers from image data, such as the gesture for pulling over.

[0121] Optionally, in step 23, an action command is sent to the control component to control the autonomous vehicle to respond to the gesture.

[0122] Based on the recognized hand gesture, the main control module of the autonomous vehicle sends action commands to the control components, such as executing a command to pull over to the side of the road, in order to control the autonomous vehicle to respond to the hand gesture.

[0123] Step 24: Send the first voice data to prompt law enforcement officers to show their identification for law enforcement purposes.

[0124] After executing the action command, the self-driving car sends out the first voice data, which is used to prompt law enforcement officers to show their identification for law enforcement purposes. For example, it sends a preset standard voice clip or a voice clip pre-recorded by the user. The content of the voice clip could be, for example, "Please show your law enforcement certificate" or "Please show your valid identification."

[0125] Step 25: Receive relevant data for law enforcement credentials, which is image data of the credentials collected by the credential receiving module.

[0126] After sending the first voice data, wait for a preset time, and then start the document receiving module to collect relevant data of the document. The document receiving module can be an image acquisition device or voice. For example, the image acquisition device can capture the image of the document, or the voice acquisition device can capture the document number spoken by the law enforcement officer. The information used to identify the legal identity of the law enforcement officer in the document can be extracted through image detection or voiceprint recognition technology. All of this information belongs to the relevant data of the document.

[0127] Step 26: Extract identity information from the image data of the document.

[0128] Based on the collected image data of the identification documents, the identity information of the law enforcement officers is extracted from the documents. Identification documents may include, for example, police identification cards. Identity information may include, for example, the holder's name, gender, date of birth, position, rank, badge number, and an image of the holder.

[0129] Step 27: Determine whether the document is a valid document based on the identity information.

[0130] After obtaining the identity information from the document, the authenticity of the identity information is verified. For example, this could be done by the main control module of an autonomous vehicle and / or the processing device of a cloud platform.

[0131] For example, the main control module of an autonomous vehicle can verify the legitimacy of identity information, or transmit the identity information to a cloud platform in an encrypted manner, where the cloud platform can verify the authenticity of the identity information.

[0132] The system can also extract identity information through the main control module, transmit the identity information as feature data to the cloud platform for authenticity verification, and feed the result of authenticity verification back to the autonomous vehicle as the result of legality judgment. Based on the result of legality judgment, the system can control the relevant operations of the autonomous vehicle. For example, if the document is legal, the autonomous vehicle can control the window glass to move towards the ground to open the window, so that the audio data inside the autonomous vehicle can be transmitted.

[0133] If the identification is deemed invalid, the identity of the law enforcement officer may be questionable. In this case, the self-driving car sends image data of the suspicious person to the cloud platform to improve the system's security.

[0134] Step 271: If the documents are valid, then receive second voice data input by law enforcement officers, which includes prompts for the autonomous vehicle to provide information indicating its legal driving.

[0135] After verifying the validity of the documents and following a period of waiting or brief conversation, the autonomous vehicle's voice acquisition device collects second-level voice data and performs speech recognition to obtain keywords. The autonomous vehicle's operation is then controlled based on these keywords. For example, if the keyword is "permit," the main control module retrieves the image or audio data of the "permit" from the autonomous vehicle's storage device.

[0136] Step 272: If the document is invalid, send an alarm request to the cloud platform and / or send the collected image data of the law enforcement personnel, and wait for the instruction information returned by the cloud platform.

[0137] If the identification is deemed invalid, an alarm request will be sent to the cloud platform. Alternatively, the alarm request may include image data of the law enforcement personnel for further verification by the cloud platform. The autonomous vehicle waits for instructions from the cloud platform within a preset time frame and executes relevant operations accordingly. If the preset time frame is exceeded, the autonomous vehicle will sound an alarm or flash its lights.

[0138] Optionally, in step 28, information used to indicate that the driver is legally driving is sent to a voice player or display device in either voice or image data format.

[0139] After acquiring information indicating its legal driving status, the information is presented via the autonomous vehicle's voice player or display device in either voice or image data format. This legal driving information could be, for example, a permit or other document demonstrating the driver's qualifications. The display device could be, for example, the autonomous vehicle's in-vehicle display, windshield, window, or navigation display.

[0140] Optionally, in step 29, after the interaction ends, the interaction data is uploaded to the cloud platform.

[0141] To further manage the driving behavior of autonomous vehicles, the interaction information between autonomous vehicles and law enforcement personnel can be automatically stored as logs on appropriate storage devices, such as the autonomous vehicle's own storage device, cloud platform storage device, or other removable storage devices. After the interaction between the autonomous vehicle and law enforcement personnel ends, all content of the interaction is packaged and uploaded to the cloud platform using either encrypted or unencrypted methods.
