DETAILED DESCRIPTION

[0061] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0062] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0063] The existing vehicle black box stores the vehicle's dynamic information in real time in the storage module when the vehicle is driving normally. Once the vehicle's sensors detect abnormal conditions such as severe collisions, sudden braking or rollovers, the communication module is immediately activated to upload the data to the cloud. Although this technology can solve some data loss problems, in serious accidents, such as vehicle fires or falling into a river, the vehicle's black box will still be physically damaged, resulting in data loss.

[0064] Figure 1 A schematic diagram of the structure of a vehicle black box provided by an embodiment of the present disclosure is shown in FIG. Figure 1 As shown, the vehicle black box 100 includes: a data storage device 1, a control device 2 and a power device 3; the control device 2 is electrically connected to the data storage device 1 and the power device 3 respectively; the data storage device 1 is used to store vehicle status information, and the control device 2 controls the power device 3 based on a trigger instruction to drive the vehicle black box 100 to fly away from the vehicle.

[0065] Specifically, Figure 1 As shown, the sensors on the vehicle will collect the vehicle status information in real time during the driving process and send it to the vehicle black box 100. The data storage device 1 in the vehicle black box 100 is used to store the vehicle status information sent by the vehicle, such as the vehicle's driving speed, time, braking status, mileage, and other status information about the vehicle. When a serious accident occurs to the vehicle, the vehicle can send a trigger instruction to the control device 2. The control device 2 controls the power device 3 to provide flight power according to the trigger instruction, driving the vehicle black box 100 to fly away from the vehicle and away from the accident scene, thereby avoiding the problem that the vehicle black box 100 is damaged together with the vehicle after a serious accident occurs, resulting in the complete loss of data vehicle status information, thereby improving the reliability of the vehicle black box 100 and reducing the risk of data loss.

[0066] In some embodiments, for example, a base may be provided on the top of the vehicle, and a first magnetic attraction structure may be provided on the base. A second magnetic attraction structure may be provided at the bottom of the vehicle black box 100. When the first magnetic attraction structure and the second magnetic attraction structure are magnetically attracted, the vehicle black box 100 is installed on the base of the vehicle. The control device 2 controls the power device 3 to provide flight power according to the trigger instruction. When the upward flight power of the power device 3 on the vehicle black box 100 is greater than the downward magnetic attraction force of the vehicle on the vehicle black box 100, the vehicle black box 100 flies away from the vehicle.

[0067] In other embodiments, the bottom of the vehicle black box 100 can be connected and fixed to a base on the top of the vehicle by a locking device, for example. The control device 2 controls the locking device to unlock based on a trigger instruction, thereby releasing the connection between the vehicle black box 100 and the vehicle, so that the vehicle black box 100 can fly away from the vehicle based on the power provided by the power device 3.

[0068] The vehicle black box 100 provided in the embodiment of the present disclosure includes a data storage device 1, a control device 2 and a power device 3. The control device 2 controls the power device 3 that provides flight power according to a trigger instruction to drive the vehicle black box 100 to fly away from the vehicle and away from the accident scene, thereby avoiding the problem that the vehicle black box 100 is damaged together with the vehicle after a serious accident occurs, resulting in the loss of data such as vehicle status information, so that the vehicle black box 100 is out of dangerous scenes, the reliability of the use of the vehicle black box 100 is improved, and the risk of data loss is reduced.

[0069] Figure 2 A schematic cross-sectional structure diagram of a vehicle black box provided by an embodiment of the present disclosure. Figure 2 As shown, the power device 3 includes a motor 31 and a rotor 32, and the motor 31 is electrically connected to the control device 2; the control device 2 controls the motor 31 to start based on a trigger instruction, and the motor 31 drives the rotor 32 to rotate to drive the vehicle black box 100 to fly away from the vehicle.

[0070] Specifically, Figure 2 As shown, the motor 31 can be electrically connected to the control device 2, for example. The control device 2 controls the motor 31 to start based on a trigger instruction. After the motor 31 starts, it drives the rotor 32 to rotate, so that the vehicle black box 100 can fly away from the vehicle.

[0071] Figure 2 The rotor 32 is exemplarily shown as a fixed rotor 32, the motor 31 is arranged inside the shell 10 of the vehicle black box 100, the fixed shaft 321 and the fixed wing 322 of the fixed rotor 32 are arranged outside the shell 10 of the vehicle black box 100, and after the motor 31 is started, the fixed shaft 321 and the fixed wing 322 are driven to rotate, thereby driving the vehicle black box 100 to start flying and fly away from the vehicle.

[0072] Figure 3 A schematic cross-sectional structure diagram of another vehicle black box provided by an embodiment of the present disclosure. Figure 3 As shown, the rotor 32 includes a folding structure, the vehicle black box 100 also includes a shell 10, and the motor 31 and the folding structure are both arranged in the shell 10; the control device 2 controls the motor 31 to start based on the trigger instruction, and the motor 31 drives the folding structure to extend out of the shell 10 and then rotate, so as to drive the vehicle black box 100 to fly away from the vehicle.

[0073] Specifically, Figure 3 As shown, the rotor 32 may include a folding structure, and the folding structure may include a folding shaft 323 and a folding wing 324. The motor 31, the folding shaft 323 and the folding wing 324 are all arranged inside the housing 10 when the vehicle black box 100 travels with the vehicle. When the control device 2 controls the motor 31 to start, the motor 31 drives the folding shaft 323 and the folding wing 324 to extend out of the housing 10 from the opening 33 on the housing 10. After the folding shaft 323 unfolds the folding wing 324, the vehicle black box 100 is driven to start flying and fly away from the vehicle through the rotation of the folding wing 324. Therefore, the folding structure is arranged in the power device 3 to reduce the volume of the vehicle black box 100 occupied by the power device 3, which is conducive to the miniaturization of the vehicle black box 100.

[0074] Figure 4 A schematic diagram of a structure in which a rotor is located inside a housing of a vehicle black box provided in an embodiment of the present disclosure, Figure 5 A schematic diagram of a structure of a rotor extending out of a housing of a vehicle black box provided in an embodiment of the present disclosure. Figure 4 and Figure 5 When the folding structure is not unfolded, it is located inside the housing 10 of the vehicle black box 100, and the control device 2 controls the motor based on the trigger instruction ( Figure 4 and Figure 5 The folding shaft 323 is started by the motor, and the folding wing 324 is rotated inside the housing 10 by the motor. The rotation of the folding wing 324 provides a small lift for the vehicle black box 100, and drives the vehicle black box 100 to fly away from the vehicle. For example, a distance sensor can be installed at the bottom of the vehicle. Based on the distance sensor detecting that the distance between the vehicle black box 100 and the bottom of the vehicle is greater than the preset distance, the vehicle sends a rotor deployment instruction to the control device 2. The control device 2 controls the motor to drive the folding shaft 323 and the folding wing 324 to extend from the opening on the housing 10 to the housing 10 based on the rotor deployment instruction, and unfolds the folding wing 324 to drive the vehicle black box 100 to continue flying. Exemplarily, the folding wing 324 can be set at the inner edge of the housing 10 so that the folding wing 324 directly extends out of the housing 10, providing greater lift to the vehicle black box 100.

[0075] Exemplarily, the opening 33 of the shell 10 may be provided on the upper surface or the side of the shell 10 , so as to facilitate the folding flap 324 to extend out of the shell 10 , and the embodiment of the present disclosure is not limited to this.

[0076] Figure 6 A schematic diagram of another vehicle black box provided by an embodiment of the present disclosure. Figure 6As shown, the vehicle black box 100 also includes: a communication device 4; the communication device 4 is electrically connected to the data storage device 1 and the control device 2 respectively; the communication device 4 obtains the vehicle status information through the data storage device 1, and the control device 2 controls the communication device 4 to upload the vehicle status information and / or alarm information to the cloud based on the trigger instruction.

[0077] Specifically, Figure 6 As shown, the vehicle black box 100 further includes a communication device 4, which is electrically connected to the data storage device 1 and the control device 2, respectively. The control device 2 sends an activation instruction to the communication device 4 according to the trigger instruction to activate the communication device 4. The activated communication device 4 obtains the vehicle status information through the data storage device 1, and uploads the vehicle status information to the cloud, so that relevant personnel can analyze the cause of the vehicle accident. The activated communication device 4 can also upload the alarm information to the cloud to prompt the search and rescue personnel to rescue the vehicle in time.

[0078] It should be noted that the communication device 4 may upload only the vehicle status information to the cloud, or may upload only the alarm information to the cloud, or may upload both the vehicle status information and the alarm information to the cloud, which is not limited in the embodiments of the present disclosure.

[0079] Alternatively, if Figure 6 As shown, the communication device 4 is also used to search for a position where the communication signal strength is greater than a preset signal strength threshold and send a hovering command to the control device 2; the control device 2 controls the power device 3 to drive the vehicle black box 100 to hover at the current position based on the hovering command, and controls the communication device 4 to upload the vehicle status information and / or alarm information to the cloud.

[0080] Specifically, Figure 6 As shown, since the scene of the vehicle accident may be located in a remote mountainous area or other location with weak communication signals, in order for the communication device 4 to successfully upload the vehicle status information and / or alarm information to the cloud, the communication device 4 also needs to search for the signal source. When the communication device 4 searches for a location where the communication signal strength is greater than a preset signal strength threshold, it sends a hovering instruction to the control device 2, so that the control device 2 controls the power device 3 to drive the vehicle black box 100 to hover at the current position. The communication device 4 uploads the vehicle status information and / or alarm information to the cloud at the location where the vehicle black box 100 is hovering, thereby improving the success rate of uploading the vehicle status information and / or alarm information to the cloud. In the case of insufficient signal coverage or damaged equipment, the stability and reliability of the remote alarm function are ensured, and the problem of upload interruption caused by poor communication signals is avoided, so that the background personnel can understand the vehicle status in a timely manner.

[0081] Alternatively, if Figure 6As shown, the communication device 4 is also used to send a return command to the control device 2 after uploading the vehicle status information and / or alarm information. The control device 2 controls the power device 3 to drive the vehicle black box 100 to return to the preset position based on the return command.

[0082] Specifically, Figure 6 As shown, after the communication device 4 completes uploading the vehicle status information and / or alarm information, it sends a return command to the control device 2. After receiving the return command, the control device 2 controls the power device 3 to provide power so that the vehicle black box 100 flies back to the preset position, making it easier for search and rescue personnel to find the vehicle black box 100 and preventing the loss of encrypted data in the vehicle black box 100 that has not been uploaded to the cloud.

[0083] Figure 7 A schematic diagram of another vehicle black box provided by an embodiment of the present disclosure. Figure 7 As shown, the vehicle black box 100 also includes: an environment detection device 5, which is electrically connected to the data storage device 1 and the control device 2 respectively; the environment detection device 5 is used to collect the surrounding environment data of the vehicle black box 100 and send it to the data storage device 1 and the control device 2, and the control device 2 determines the preset position based on the surrounding environment data of the vehicle black box 100.

[0084] Specifically, Figure 7 As shown, the environment detection device 5 may include, for example, an environment sensor, an image acquisition module, and a GPS sensor. The environment sensor may collect on-site data such as temperature, humidity, and gas concentration. The image acquisition module may include, for example, a camera and a gimbal module. The camera may collect pictures or videos of the environment surrounding the vehicle black box 100. The gimbal supports a multi-axis stable design to ensure that the vehicle black box 100 can capture stable images during flight. The GPS sensor may, for example, perform real-time positioning.

[0085] Compared with the data storage device 1 in the related art, which is mainly used for static data storage and the data collection scope is limited to the vehicle, it is impossible to further collect the surrounding environment information (such as the fire range, obstacles, personnel status, etc.) after the accident, and it is difficult to provide comprehensive on-site information for subsequent accident analysis and rescue. The environmental detection device 5 can continue to collect the surrounding environment data of the accident scene after the accident occurs, and send it to the communication device 4 through the data storage device 1, and the communication device 4 uploads it to the cloud, providing more comprehensive data support for accident rescue and responsibility analysis. In addition, the surrounding environment data of the accident scene collected by the environmental detection device 5 is also used to determine the preset position. The preset position can be, for example, the location of the vehicle, which is convenient for the vehicle black box 100 to draw power from the vehicle, and it is also convenient for search and rescue personnel to find the vehicle black box 100 to prevent the vehicle black box 100 from being lost. When the vehicle is seriously damaged, for example, due to falling into a river or fire, etc., which makes it inconvenient for the vehicle black box 100 to be parked on the vehicle, the control device 2 can find a grass or flat road position within a preset distance from the vehicle as a preset position based on the surrounding environment data of the vehicle black box 100 collected by the environment detection device 5, so that the vehicle black box 100 can be parked at the preset position, thereby reducing the risk of damage to the vehicle black box 100, simplifying the workload of people searching for the vehicle black box 100, and saving a lot of manpower and material resources.

[0086] In some embodiments, the control device 2 may, for example, pre-store a flight path, and the environmental detection device 5 is used to monitor environmental information in real time. The control device 2 can adjust the flight path according to the real-time monitored environmental information during the flight of the vehicle black box 100, so as to avoid obstacles. Obstacles may include all static obstacles and dynamic obstacles within a preset range around the vehicle black box 100 that may affect the flight trajectory of the vehicle black box 100. Among them, the preset range can be determined according to the perception range of the vehicle black box 100, and can also be set according to actual flight requirements. The environmental detection device 5 may, for example, include ultrasonic radar, millimeter wave radar, laser radar and panoramic camera, etc., which are not limited in the embodiments of the present disclosure.

[0087] Optionally, the communication device 4 includes at least one of a cellular communication module, a satellite communication module and a short-range communication module.

[0088] Although some networked black boxes have data upload functions, they need to rely on communication signal coverage. In remote areas or signal blocked scenarios, the remote alarm function may fail. To solve the above problems, the communication device 4 provided in the embodiment of the present disclosure may include at least two of a cellular communication module, a satellite communication module, and a short-range communication module. Since the cellular signal is used to transmit data at a fast speed and cellular signal communication can be achieved in most areas, the communication device 4 may include a cellular communication module and a satellite communication module, or a cellular communication module and a short-range communication module, or a cellular communication module, a satellite communication module, and a short-range communication module. The communication device 4 may preferentially use the cellular communication module for communication. When the signal strength of the cellular signal is less than the preset signal strength threshold, it may switch to the satellite communication module or the short-range communication module for communication and upload vehicle status information and / or alarm information. Exemplarily, the cellular communication module includes, for example, 4G or 5G communication, and the short-range communication module may, for example, use the LoRa protocol to directly communicate with nearby rescue equipment within a short distance.

[0089] Therefore, through the redundant setting of the communication module, it can be ensured that the communication device 4 can successfully send the vehicle status information and / or alarm information in various environments.

[0090] In some embodiments, the vehicle black box 100 also includes a backup power supply device. Even if the vehicle power supply system is completely cut off from power supply, the vehicle black box 100 can use the backup power supply device to complete the operation of starting and flying away from the vehicle, ensuring the reliability of the vehicle black box 100, and ensuring that the vehicle black box 100 can respond quickly when the vehicle cannot be used or is damaged, effectively improving the efficiency of collecting accident information and emergency handling capabilities.

[0091] In some embodiments, the housing 10 of the vehicle black box 100 can be made of high temperature resistant and impact resistant composite materials, and an inner and outer double-layer heat insulation structure is provided, and an efficient heat dissipation structure is designed to cope with fire or high temperature environment, so as to further enhance the survivability of the vehicle black box 100. Built-in key components such as data storage device 1, control device 2, communication device 4, environmental detection device 5, etc. can further adopt a heat insulation protective layer to ensure the stable operation of the vehicle black box 100 under extreme conditions. A thermal isolation material is designed between the built-in key components and the power device 3 to prevent high temperature transfer from affecting the operation of the vehicle black box 100.

[0092] In some embodiments, the vehicle black box 100 also includes a data interface for routine system maintenance and data export.

[0093] In some embodiments, an airbag structure may be provided outside the housing 10 of the vehicle black box 100 to avoid direct damage in the event of a collision or fire, or in a water environment, the airbag structure may be deployed to allow the vehicle black box 100 to float on the water.

[0094] The disclosed embodiment also provides a method for controlling a vehicle black box, which is applicable to the vehicle black box provided in the above embodiment. Figure 8 The flowchart of a vehicle black box control method provided by the embodiment of the present disclosure is shown in FIG. The vehicle black box control method can be applied to application scenarios where the vehicle black box needs to be controlled on the fly, and can be executed by a vehicle black box control device, which can be implemented in software and / or hardware. Figure 8 As shown, the method comprises the following steps:

[0095] S101, obtaining a trigger instruction.

[0096] Exemplarily, the trigger instruction may be issued by the vehicle, or may be issued by a mobile terminal device that is communicatively connected to the vehicle. The embodiment of the present disclosure does not limit the sender of the trigger instruction.

[0097] S102. Based on the trigger command, control the power device to drive the vehicle black box to fly away from the vehicle.

[0098] Specifically, the control device controls the power device to provide power based on the trigger instruction, thereby driving the vehicle black box to fly away from the vehicle and away from the accident scene. This can avoid the problem of the vehicle black box being damaged together with the vehicle after a serious accident, resulting in the loss of data such as vehicle status information, thereby improving the reliability of the vehicle black box and reducing the risk of data loss.

[0099] Optionally, controlling the power device to drive the vehicle black box to fly away from the vehicle based on the trigger instruction includes: controlling the folding structure to extend out of the shell and then rotate based on the trigger instruction to drive the vehicle black box to fly away from the vehicle.

[0100] Specifically, the folding structure may include, for example, a folding shaft and folding wings. The motor, folding shaft and folding wings are all arranged inside the shell when the vehicle black box is traveling with the vehicle. After the control device receives a trigger command, it controls the motor to start, thereby driving the folding shaft and folding wings to extend out of the shell. After the folding shaft unfolds the folding wings, the rotation of the folding wings drives the vehicle black box to start flying and fly away from the vehicle.

[0101] Optionally, after controlling the power device to drive the vehicle black box to fly away from the vehicle based on the trigger instruction, it includes: controlling the communication device to upload the vehicle status information and / or alarm information to the cloud.

[0102] Specifically, after the power device drives the vehicle black box to fly away from the vehicle, the control device controls the communication device to upload the vehicle status information to the cloud, so that relevant personnel can analyze the cause of the vehicle accident. The control device can also control the communication device to upload the alarm information to the cloud to prompt the search and rescue personnel to rescue the vehicle in time.

[0103] Optionally, before controlling the communication device to upload the vehicle status information and / or alarm information to the cloud, it also includes: obtaining a hovering instruction; wherein the hovering instruction is issued after the communication device searches for a position where the communication signal strength is greater than a preset strength threshold; based on the hovering instruction, controlling the power device to drive the vehicle black box to hover at the current position.

[0104] Specifically, before the communication device uploads the vehicle status information and / or alarm information to the cloud, it is necessary to search for the signal source. When the communication device searches for a position where the communication signal strength is greater than a preset signal strength threshold, it sends a hovering command to the control device. The control device controls the power device to drive the vehicle black box to hover at the current position based on the hovering command. The communication device uploads the vehicle status information and / or alarm information to the cloud at the position where the vehicle black box is hovering, thereby improving the success rate of uploading the vehicle status information and / or alarm information to the cloud, avoiding the problem of upload interruption caused by poor communication signals, and facilitating background personnel to understand the vehicle condition in a timely manner and carry out rescue.

[0105] Optionally, after controlling the communication device to upload the vehicle status information and / or alarm information to the cloud, it also includes: obtaining a return instruction; wherein the return instruction is sent after the communication device completes uploading the vehicle status information and / or alarm information to the cloud; based on the return instruction, controlling the power device to drive the vehicle black box to return to a preset position.

[0106] Specifically, after the communication device uploads the vehicle status information and / or alarm information to the cloud, the communication device sends a return command to the control device. After receiving the return command, the control device controls the power device to provide power to make the vehicle black box fly back to a preset position, making it easier for search and rescue personnel to find the vehicle black box and preventing the loss of encrypted data in the vehicle black box that has not been uploaded to the cloud.

[0107] Optionally, controlling the power device to drive the vehicle black box back to a preset position based on a return instruction includes: acquiring vehicle surrounding environment data; determining a preset position based on the vehicle surrounding environment data; determining a return path according to the preset position; and controlling the power device to drive the vehicle black box back to the preset position according to the return path.

[0108] Specifically, the vehicle surrounding environment data collected by the environment detection device is sent to the control device, and the control device determines a preset position based on the vehicle surrounding environment data. The preset position can be, for example, the location of the vehicle. Controlling the vehicle black box to return to the vehicle facilitates the vehicle black box to draw power from the vehicle, and also facilitates search and rescue personnel to find the vehicle black box to prevent the vehicle black box from being lost. When the vehicle is severely damaged, the control device can determine a location such as a bush or a flat road within a preset distance from the vehicle as a preset position based on the image collected by the environment detection device to reduce the risk of damage to the vehicle black box.

[0109] The coordinates of the preset position and the current position are obtained, the return path is determined according to the coordinates of the preset position and the current position, and the power device is controlled to drive the vehicle black box to return to the preset position along the return path and stop, waiting for the search of rescue personnel, which simplifies the workload of people searching for the vehicle black box and saves a lot of manpower and material resources.

[0110] The disclosed embodiment also provides a control system for a vehicle black box. Fig. 9 The structure diagram of a control system of a vehicle black box provided by the embodiment of the present disclosure is as follows. Fig. 9 As shown, the control system of the vehicle black box includes: a vehicle detection device 6; a vehicle control device 7; and a vehicle black box 100 as provided in the above embodiment; the vehicle control device 7 is electrically connected to the vehicle detection device 6 and the vehicle black box respectively, and the vehicle detection device 6 is electrically connected to the vehicle black box 100; the vehicle detection device 6 is used to send vehicle status information to the vehicle black box 100 and the vehicle control device 7, and the vehicle control device 7 sends a trigger instruction to the vehicle black box 100 based on the vehicle status information satisfying the preset accident condition, so as to make the vehicle black box 100 fly away from the vehicle.

[0111] Specifically, Fig. 9 As shown, the vehicle detection device 6 is used to detect vehicle status information, such as the vehicle's driving speed, time, braking status, mileage and other status information about the vehicle, and send the vehicle status information to the vehicle black box 100, which is stored by the data storage device 1 in the vehicle black box 100.

[0112] The vehicle detection device 6 also sends the vehicle status information to the vehicle control device 7, and analyzes whether the vehicle is in an unusable or damaged state through the algorithm built into the vehicle control device 7. The vehicle control device 7 satisfies the preset accident conditions based on the driving status information, indicating that the vehicle has had a serious accident. If the vehicle black box 100 is left on the vehicle, it will be damaged along with the vehicle. Therefore, the vehicle control device 7 sends a trigger instruction to the vehicle black box 100 to make the vehicle black box 100 fly away from the vehicle and away from the accident scene, thereby avoiding the problem of the vehicle black box 100 being damaged along with the vehicle after a serious accident, which leads to the loss of data such as the vehicle status information, thereby improving the reliability of the vehicle black box 100 and reducing the risk of data loss.

[0113] Optionally, the vehicle detection device 6 includes at least one of an acceleration sensor, a tilt sensor, a temperature sensor, a smoke sensor, a power supply detection sensor, a GPS sensor and a speed sensor.

[0114] Specifically, acceleration sensors include, for example, gyroscopes and accelerometers, which are installed at the front, rear, or key locations of the vehicle to detect the acceleration and collision intensity of the vehicle. Tilt sensors are used to detect whether the vehicle's tilt angle exceeds a safe range and to detect whether the vehicle rolls or overturns. Temperature sensors and smoke sensors can be installed inside and outside the vehicle. The temperature sensor is used to detect temperature changes, and the smoke sensor is used to detect smoke concentration. The power supply detection sensor monitors whether the vehicle's power supply system is powered off or whether the battery is over-discharged.

[0115] The vehicle control device 7 sends a trigger instruction to the vehicle black box 100 to make the vehicle black box 100 fly away from the vehicle based on at least one of the vehicle's acceleration being greater than a preset acceleration threshold, the vehicle's collision intensity being greater than a preset intensity threshold, the vehicle's tilt angle being greater than a preset tilt angle threshold, the vehicle's temperature being greater than a preset temperature threshold, the vehicle's smoke concentration value being greater than a preset concentration threshold, and the vehicle's power supply status being abnormal.

[0116] The GPS sensor is used to detect the location of the vehicle, and the speed sensor is used to detect the driving speed of the vehicle. The GPS sensor and the speed sensor are used in combination to determine whether the vehicle is stagnant in an abnormal position for a long time. The vehicle control device 7 sends an inquiry message to the vehicle based on the vehicle's driving speed being less than a preset speed threshold and the vehicle deviating from the preset driving route. If the vehicle control device 7 does not receive feedback information from the vehicle within the preset time, indicating that the vehicle accident is serious and the occupants are unable to send feedback information, a trigger command is sent to the vehicle black box 100 to make the vehicle black box 100 fly away from the vehicle.

[0117] Therefore, through the fusion algorithm of multiple sensors, the accuracy of accident identification is improved, the probability of the vehicle black box 100 being mistakenly triggered to fly away from the vehicle is reduced, and the accuracy of controlling the vehicle black box 100 is improved.

The vehicle black box is also provided parallel to the ground to achieve vertical takeoff of the vehicle black box. When the control device receives a trigger command, it controls to release the lock of the base, the vehicle black box is separated from the base, and the vehicle black box is driven to fly by the power device.

[0120] The vehicle black box, control method, control system and vehicle provided by the disclosed embodiment, through the control device to control the power device to provide flight power according to the trigger command, drive the vehicle black box to fly away from the vehicle and away from the accident scene, which can avoid the problem of the vehicle black box being damaged together with the vehicle after a serious accident, resulting in the loss of data such as vehicle status information, improves the reliability of the vehicle black box, and reduces the risk of data loss. It realizes the ability of data protection, on-site recording and remote alarm functions after the vehicle completely loses its function, greatly improving the data availability and rescue efficiency after the accident.
