The core idea of ​​​​eCall is to use the on-board satellite positioning platform to obtain vehicle-related information such as vehicle location information to form MSD (Minimum Set of Data) data.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application and have no specific meaning. Therefore, "module" and "component" can be used interchangeably.

[0031] Since the 1990s, cars and communications have come together, and cars have been equipped with mobile communication devices based on 2G, 3G, 4G and 5G. With these devices, services such as navigation and information forecasting based on communication capabilities have gradually been realized. After having 2G cellular communication capabilities, intelligent transportation has adopted the eCall (emergencyCall, on-board emergency call) function to solve traffic safety. The core idea of ​​​​eCall is to use the on-board satellite positioning platform to obtain vehicle-related information such as vehicle location information to form MSD (Minimum Set of Data) data. After an accident occurs, the sensor detection triggers an automatic alarm or the user manually initiates an emergency call to alarm, and the MSD data is automatically sent to the PSAP (public safety answering point) of the rescue center, so that the rescue center can locate the accident vehicle and organize rescue.

[0032] When a vehicle or its occupants encounter an emergency, if the occupants are unable to clearly describe the circumstances of the accident, the rescue center can only rely on MSD data to determine the circumstances of the accident before dispatching rescue personnel to the scene. However, the rescue center cannot make a comprehensive and accurate judgment of the accident scene based solely on MSD data, and therefore cannot make the best targeted rescue decisions.

[0033] In order to solve the problems mentioned in the background technology, according to one aspect of the embodiment of the present application, a vehicle emergency rescue system is provided, such as Figure 1 As shown, the rescue system includes: a rescue service platform 102 and an on-board platform 104 of the target vehicle, wherein the on-board platform 104 is used to obtain the MSD data of the target vehicle when an accident is detected in the target vehicle; send the MSD data to the rescue service platform 102, wherein the MSD data carries a key for controlling the camera of the target vehicle; receive the ciphertext control instructions sent by the rescue service platform 102, and control the camera according to the ciphertext control instructions to collect the live image of the accident scene through the camera; transmit the live image to the rescue service platform 102 in real time; the rescue service platform 102 is used to extract the accident information and the key of the target vehicle from the MSD data when receiving the MSD data sent by the on-board platform 104; generate a plaintext control instruction, and encrypt the plaintext control instruction with the key to obtain the ciphertext control instruction; send the ciphertext control instruction to the on-board platform 104; receive the live image sent by the on-board platform 104, and generate a rescue strategy according to the live image and the accident information, so as to rescue the target vehicle according to the rescue strategy.

[0034] The entire rescue system is divided into two parts: accident detection, data collection and transmission on the vehicle platform, and data reception, command sending and rescue strategy formulation on the rescue service platform. Through two-way encrypted communication and real-time image transmission, the rescue service platform can accurately obtain accident scene information and formulate timely rescue plans, effectively improving the rescue response speed and efficiency.

[0035] Figure 2 The interactive schematic diagram of the vehicle emergency rescue system provided for this application, as shown in the figure, the system includes IVS (In-Vehicle System) and PSAP, IVS corresponds to the vehicle platform of this application, and PSAP corresponds to the rescue service platform of this application. The vehicle's IVS triggers eCall when an accident occurs, and automatically reports the MSD data carrying the key to PSAP. PSAP can use the key to remotely control the vehicle camera to collect live images. IVS transmits the collected live images to PSAP in real time. PSAP determines the accident situation based on the MSD data and live images and formulates rescue strategies in a targeted manner, dispatches rescue personnel to the scene for rescue, and can also remotely guide the accident personnel to save themselves through voice calls.

[0036] The present application provides a vehicle emergency rescue system, which includes a rescue service platform and an on-board platform of a target vehicle, wherein the on-board platform is used to obtain MSD data of the target vehicle when an accident is detected in the target vehicle; send the MSD data to the rescue service platform, wherein the MSD data carries a key for controlling a camera of the target vehicle; receive ciphertext control instructions sent by the rescue service platform, and control the camera according to the ciphertext control instructions to collect live images of the accident scene through the camera; transmit the live images to the rescue service platform in real time; the rescue service platform is used to extract accident information and keys of the target vehicle from the MSD data when receiving the MSD data sent by the on-board platform; generate plaintext control instructions, and encrypt the plaintext control instructions with the key to obtain ciphertext control instructions; send the ciphertext control instructions to the on-board platform; receive the live images sent by the on-board platform, and generate a rescue strategy based on the live images and accident information to rescue the target vehicle according to the rescue strategy. When a vehicle encounters an accident, the on-board platform reports the MSD data and the key used to control the target vehicle camera at the same time. The rescue service platform can control the vehicle camera to collect live images of the scene according to the key, and then comprehensively judge the accident situation based on the live images and MSD data, and formulate a targeted rescue plan. This solves the problem that the rescue center cannot make a comprehensive and accurate judgment of the accident scene based on MSD data alone.

[0037] According to another aspect of the embodiments of the present application, the present application provides a vehicle emergency rescue method, which is applied to a vehicle-mounted platform of a target vehicle, such as Figure 3 As shown, including:

[0038] Step 301, when an accident of a target vehicle is detected, obtaining MSD data of the target vehicle;

[0039] Step 303, sending MSD data to the rescue service platform, wherein the MSD data carries a key for controlling a camera of the target vehicle;

[0040] Step 305, receiving the encrypted control instruction sent by the rescue service platform, and controlling the camera according to the encrypted control instruction to collect a live image of the accident scene through the camera;

[0041] Step 307: Transmit the live image to the rescue service platform in real time.

[0042] When the vehicle-mounted platform detects that the target vehicle has an accident, it automatically triggers the rescue program, obtains the MSD data of the target vehicle, and reports the MSD data to the rescue service platform in real time through the network. The MSD data includes the vehicle's accident information and the key used to control the vehicle-mounted camera. The MSD data is used to notify the rescue service platform that the vehicle has an accident, inform the relevant information of the accident vehicle, and transmit the key for subsequent remote control of the camera.

[0043] After receiving the encrypted control instructions sent by the rescue service platform, the encrypted control instructions are decrypted using the key sent from the MSD data to obtain the corresponding plaintext control instructions, start the camera, and control the camera according to the plaintext control instructions to collect live images of the accident scene, and send the live images to the rescue service platform in real time.

[0044] Specifically, the vehicle-mounted platform has a sensor device. When an accident occurs to the target vehicle (such as a collision, rollover, etc.), the device will automatically detect the occurrence of the accident. These sensors may include accelerometers, gyroscopes, airbag sensors, etc., which are used to monitor the status and abnormal conditions of the vehicle. After detecting an accident, the vehicle-mounted platform will automatically generate and obtain a set of MSD data.

[0045] The vehicle accident information is the relevant data of the vehicle, including but not limited to the vehicle location, accident time, vehicle speed, vehicle impact force, and other conditions of the vehicle (such as whether the airbag is deployed). In this application, a key for subsequent encrypted camera control instructions is also attached to the MSD data.

[0046] After acquiring the MSD data, the vehicle platform sends the data to the rescue service platform through the network. The MSD data not only contains relevant information about the accident, but also carries a key for controlling the vehicle camera. The key will be used to encrypt and decrypt subsequent communications to ensure the security and privacy of information during camera control and image transmission.

[0047] The MSD data carrying the key will provide the rescue service platform with preliminary information about the accident situation, allowing the platform to fully and timely understand the severity and urgency of the accident.

[0048] After receiving the MSD data, the rescue service platform analyzes the accident situation and generates a plaintext control instruction for controlling the vehicle-mounted camera. To ensure the security of communication, the rescue service platform uses the key carried in the MSD data to encrypt the plaintext control instruction, generates a ciphertext control instruction and sends it to the vehicle-mounted platform.

[0049] Next, it is explained how to control the camera according to the encrypted control command after the vehicle-mounted platform receives the encrypted control command.

[0050] As an optional embodiment, controlling the camera according to the encrypted control instruction includes: decrypting the encrypted control instruction using a key to obtain a plaintext control instruction; and controlling the camera according to the plaintext control instruction to collect real-time images of the accident scene.

[0051] The rescue service platform sends ciphertext control instructions to the vehicle platform to control the camera. In order to ensure that the information will not be stolen or tampered with by a third party during transmission, the operation instructions generated by the rescue service platform are encrypted into ciphertext control instructions, which can only be decrypted by the recipient with the correct key. Since the key is transmitted to the rescue service platform in advance through the vehicle's MSD data, both the rescue service platform and the vehicle platform hold the key. The vehicle platform can use the key to decrypt the ciphertext control instructions and obtain the plaintext control instructions.

[0052] Optionally, after receiving the ciphertext control command, the ciphertext control command is decrypted using the key transmitted in the MSD data. Common encryption algorithms may include symmetric encryption algorithms, through which the vehicle-mounted platform can decrypt the encrypted command to obtain the original plaintext control command (that is, the actual operation command generated by the rescue service platform).

[0053] After obtaining the decrypted plaintext control command, the vehicle-mounted platform activates the camera of the target vehicle and starts collecting real-time images of the accident scene. The cameras involved in this application are installed at different locations outside and inside the vehicle, and the rescue service platform can obtain multi-angle views of the accident scene in real time through these cameras.

[0054] The real-time transmission of live images is to provide accurate information to the rescue platform so that the platform can formulate the best rescue strategy for timely rescue, including dispatching rescue vehicles, coordinating emergency medical resources, etc.

[0055] As an optional embodiment, when receiving the encrypted control instruction sent by the rescue service platform, the method also includes: receiving and verifying the call request sent by the rescue service platform; when the call request passes the verification, sending a confirmation response to the rescue service platform so that the rescue service platform establishes a voice channel; receiving a first voice signal sent by the rescue service platform through the voice channel, and playing first voice data corresponding to the first voice signal through a speaker; collecting second voice data at the accident scene through a microphone, and sending a second voice signal corresponding to the second voice data to the rescue service platform through the voice channel.

[0056] When an accident occurs, the rescue service platform can initiate a call request to the vehicle platform, requesting voice communication with the accident scene. After receiving the call request, the vehicle platform will perform a security verification on the request to ensure that the request comes from an authorized rescue service platform.

[0057] Authentication of the call request may be achieved through an identity authentication mechanism, such as using a pre-shared key, a digital certificate, or other encryption mechanisms for authentication.

[0058] If the call request passes the verification, the vehicle platform will send a confirmation response to the rescue service platform, indicating that the vehicle platform is ready to receive voice communication. The rescue service platform can then establish a voice communication channel (i.e., voice channel) with the vehicle platform. The establishment of this channel can be based on the Internet voice protocol or other real-time audio communication protocols.

[0059] The operator or rescuer of the rescue service platform sends a first voice signal through the voice channel. The first voice signal is collected by the microphone of the rescue platform and transmitted to the vehicle-mounted platform through the voice channel. After receiving the first voice signal, the vehicle-mounted platform will parse and process the first voice signal, and the parsed voice signal will be converted into first voice data that can be played. The vehicle-mounted platform plays the first voice data through the vehicle-mounted speaker so that people in the car can hear the voice of the rescuer. The first voice data may contain guidance, comfort, or important accident handling suggestions. This application does not limit the content of the first voice data.

[0060] When conducting two-way voice communication, the vehicle-mounted platform also needs to collect the second voice data from the accident scene. The microphone on the vehicle-mounted platform will collect the voice from the accident scene, that is, the second voice data such as conversations and calls for help from people in or around the vehicle, encode the second voice data, generate a second voice signal, and send it to the rescue service platform in real time through the established voice channel. After receiving the second voice signal, the rescue service platform will decode and play it, so that the rescue personnel can hear the sound of the accident scene in real time and communicate with the personnel on the scene in real time. If the people in the car are conscious and can express themselves correctly, they can directly inform the rescue personnel of the specific situation, which is convenient for the timely adjustment of the rescue strategy.

[0061] There is no requirement for the order of voice transmission between the rescue service platform and the vehicle-mounted platform, and the vehicle-mounted platform may send a voice signal to the rescue service platform first.

[0062] Through two-way, real-time voice communication between rescuers and personnel at the accident site, rescuers can quickly understand the details of the accident and provide guidance.

[0063] The vehicle-mounted platform not only receives and decrypts the encrypted control instructions sent by the rescue service platform, but also processes voice communication requests to realize real-time two-way voice communication between the vehicle-mounted platform and the rescue service platform. This voice communication can help rescue personnel to have direct conversations with people at the accident scene, further improving rescue efficiency.

[0064] The present application adopts a vehicle emergency rescue method applied to an on-board platform of a target vehicle, including: when an accident is detected in the target vehicle, obtaining the MSD data of the target vehicle; sending the MSD data to the rescue service platform, wherein the MSD data carries a key for controlling the camera of the target vehicle; receiving the ciphertext control instruction sent by the rescue service platform, and controlling the camera according to the ciphertext control instruction to collect the live image of the accident scene through the camera; transmitting the live image to the rescue service platform in real time. In the event of an accident, the on-board platform reports the MSD data and also reports the key for controlling the camera of the target vehicle. The rescue service platform can control the vehicle camera to collect the live image of the scene according to the key, and then comprehensively judge the accident situation according to the live image and MSD data, and formulate a targeted rescue plan. It solves the problem that the rescue center cannot make a comprehensive and accurate judgment of the accident scene based on MSD data alone.

[0065] According to another aspect of the embodiment of the present application, the present application provides a vehicle emergency rescue method, which is applied to a rescue service platform, such as Figure 4 As shown, including:

[0066] Step 401, when receiving the MSD data sent by the vehicle-mounted platform of the target vehicle, extracting the accident information and the key of the target vehicle from the MSD data;

[0067] Step 403, generating a plaintext control instruction, and encrypting the plaintext control instruction using a key to obtain a ciphertext control instruction, wherein the plaintext control instruction is used to control the camera of the target vehicle;

[0068] Step 405, sending a ciphertext control command to the vehicle-mounted platform;

[0069] Step 407, receiving the live image sent by the vehicle-mounted platform, and generating a rescue strategy based on the live image and the accident information, so as to rescue the target vehicle according to the rescue strategy.

[0070] After receiving the MSD data sent by the vehicle platform, the rescue service platform first extracts the accident information and key from it, and generates plaintext control instructions for controlling the vehicle camera based on the accident information extracted from the MSD data, indicating the specific operations of the vehicle camera (such as starting the camera, adjusting the camera angle, acquisition frequency, etc.). In order to ensure communication security, the rescue service platform uses the key extracted from the MSD data to encrypt the generated plaintext control instructions to form ciphertext control instructions.

[0071] The rescue service platform receives live images transmitted from the vehicle-mounted platform in real time. These real-time images can intuitively reflect the actual situation at the accident scene. The rescue service platform analyzes the severity of the accident and surrounding environment and other factors based on the received live images of the accident scene and the accident information in the MSD data, and generates a rescue strategy.

[0072] Based on the rescue strategy, the rescue service team can take corresponding measures, such as dispatching an ambulance, notifying the fire department or other emergency responders, to ensure that the accident is handled quickly and efficiently. Since the accident information in the live images and MSD data can provide a comprehensive display of accident details, the rescue strategy generated based on this can guide the rescue team to rescue the target vehicle and the people on board in the most effective way.

[0073] As an optional embodiment, a rescue strategy is generated based on real-time images and accident information, including: determining a first vehicle state of a target vehicle based on the accident information; determining a status of personnel on the target vehicle and scene information outside the target vehicle based on the real-time images; performing an accident assessment based on the first vehicle state, personnel state, and scene information to obtain an assessment result; and generating a rescue strategy based on the assessment result.

[0074] The accident information of the target vehicle is included in the MSD data. The rescue service platform determines the first vehicle status of the target vehicle by analyzing the accident information, that is, the physical status and safety status of the target vehicle, including: whether the vehicle is seriously damaged, the current location of the vehicle (whether it is in a dangerous environment, such as on the edge of a cliff, next to a river, etc.), the movement status of the vehicle (whether it is stationary or overturned, etc.), whether the airbag is popped out, whether the vehicle has experienced multiple collisions, etc.

[0075] The status of the people in the car can be judged through the live image. In addition, in addition to the situation of the people in the car, the live image can also reflect the scene information around the vehicle.

[0076] This application configures two camera devices for the eCALL function. Even if two vehicles collide, as long as one of the two vehicles is equipped with the eCALL function, it can collect live images of the two vehicles through the in-car camera and the outside camera, and arrange corresponding rescue resources to expand the rescue scope.

[0077] Through the first vehicle status, personnel status and scene information, the rescue service platform can fully understand the overall situation on the scene and conduct accident assessment.

[0078] Accident assessment is actually to quantify and analyze the severity, urgency and possible rescue needs of the accident. The assessment results may include: the degree of damage to the vehicle (minor, serious, scrapped), the degree of injury to the occupants (no injury, minor injury, serious injury, life-threatening), the degree of environmental danger (for example, whether there is a risk of secondary accidents, such as fire, explosion, etc.), the urgency of rescue time (for example, whether immediate rescue is required, whether special equipment is required, etc.), etc. The assessment process can be achieved through automated systems, such as image analysis technology and neural network models, or combined with the experience of rescuers.

[0079] Based on the results of the accident assessment, the rescue service platform generates targeted rescue strategies, including but not limited to: dispatching rescue resources (such as ambulances, fire trucks, police, and even special rescue forces such as helicopters); providing emergency rescue guidance (communicating directly with people in the car through voice channels to provide first aid and escape suggestions); evaluating the rescue route (combined with scene information, the rescue platform may also determine the optimal route for the rescue vehicle to ensure that the rescue force can quickly reach the scene of the accident); and subsequent vehicle operation instructions (for example, shutting down the target vehicle's engine, triggering emergency light signals, or reminding passing vehicles to pay attention and avoid).

[0080] The accident is assessed through first the vehicle status, personnel status and scene information, and then the rescue strategy is formulated based on a multi-dimensional analysis of the accident, aiming to ensure that the rescue measures are both fast and effective.

[0081] As an optional embodiment, determining the status of personnel on the target vehicle and scene information outside the target vehicle based on the live image includes: extracting a first live image and a second live image from the live image, wherein the first live image is an image captured by controlling a camera inside the target vehicle, and the second live image is an image captured by controlling a camera outside the target vehicle; determining the status of personnel on the target vehicle based on the first live image, and determining the scene information outside the target vehicle based on the second live image, wherein the scene information includes a second vehicle status of vehicles located around the target vehicle and surrounding environment information of the target vehicle.

[0082] The first real-time image is an in-vehicle image captured by controlling a camera inside the target vehicle. The camera that captures the first real-time image can be installed in the front, rear, or at multiple angles to ensure that the entire interior of the vehicle can be captured.

[0083] The second real-time image is an image captured by controlling a camera outside the target vehicle. The camera that captures the second real-time image can be installed on the outside of the vehicle (such as the front, rear, rearview mirror, etc.) to capture the environmental conditions around the vehicle. The external camera can provide a wider perspective to help rescue personnel understand whether there are other dangers around the vehicle.

[0084] Cameras inside and outside the target vehicle can work together to ensure that key information inside and outside the vehicle is collected from multiple angles.

[0085] Determine the status of people in the target vehicle based on the first live image, such as: Number of passengers: confirm whether the number of passengers in the vehicle matches the number of passengers registered in the vehicle to avoid missing passengers; Passenger health status: detect the health status of passengers through image analysis technology or manual monitoring. For example, whether there are passengers who have lost consciousness or fallen into a coma; whether there are passengers who are injured, such as obvious bleeding or other signs of trauma; whether there are passengers who are stuck or trapped in the seat or seat belt and cannot move on their own.

[0086] Scene information outside the target vehicle is determined according to the second live image, where the scene information includes second vehicle states of vehicles around the target vehicle and surrounding environment information of the target vehicle.

[0087] The second vehicle status refers to the status of other vehicles around the target vehicle. For example, whether the surrounding vehicles have collided or been damaged, whether they pose a further threat to the target vehicle (secondary collision); the safety status of the surrounding vehicles, such as whether there is a leak (fuel leak) or explosion risk.

[0088] The surrounding environment information includes: whether it is in different environments such as highways, urban roads, rural roads or tunnels; whether there are dangerous factors at the scene, such as natural disasters such as landslides, fires, floods, etc.; whether the terrain is flat, and whether there are cliffs, steep slopes and other conditions that are not conducive to rescue; pedestrians or other non-motor vehicles: determine whether there are other non-motor vehicles (such as pedestrians, bicycles or electric vehicles) at the scene of the accident that have been affected by the accident, and assess their safety status; road conditions: determine whether the road is blocked and whether emergency clearing or evacuation of surrounding vehicles or pedestrians is required so that rescue vehicles can reach the scene of the accident smoothly.

[0089] A comprehensive assessment is conducted based on the status of the people inside the car and the scene outside the car, and then a rescue strategy is formulated. For example, if the condition of the people inside the car is critical (such as serious injuries) and the external environment is unfavorable (such as dangers such as fuel leaks or fires), the rescue strategy may give priority to emergency rescue measures, mobilizing fire forces, medical emergency personnel, etc.; if the environment outside the car is relatively safe, but the people inside the car are troubled (such as unable to leave the vehicle), the rescue service platform may provide emergency escape suggestions through the voice channel and wait for professional rescue to arrive.

[0090] By simultaneously analyzing the first live image (camera inside the vehicle) and the second live image (camera outside the vehicle), the rescue service platform can fully understand the situation at the accident scene. The first live image provides key information on the health status and injuries of the passengers, and the second live image provides information on the environment around the vehicle, the status of other vehicles, and potential risks. By combining these two images, the rescue platform can make a more accurate and effective accident assessment and formulate appropriate rescue strategies to ensure the safety of people at the accident scene.

[0091] As an optional embodiment, when sending a ciphertext control instruction to the vehicle-mounted platform, the method also includes: sending a call request to the vehicle-mounted platform, and establishing a voice channel when receiving a confirmation response returned by the vehicle-mounted platform; collecting the first voice data of the rescue personnel, and sending a first voice signal corresponding to the first voice data to the vehicle-mounted platform through the voice channel; receiving a second voice signal sent by the vehicle-mounted platform, and playing second voice data corresponding to the second voice signal.

[0092] Sending a call request to the vehicle-mounted platform indicates that the rescue service platform hopes to conduct voice communication with the vehicle-mounted platform of the target vehicle. After receiving the confirmation response returned by the vehicle-mounted platform in response to the call request, the rescue service platform and the vehicle-mounted platform will establish a voice channel, so that the voice data at both ends can be transmitted in real time through the channel.

[0093] The generation and transmission method of voice data between the rescue service platform and the vehicle platform have been explained above and will not be repeated here.

[0094] Through two-way voice communication, the rescue service platform can grasp the situation at the accident scene more quickly and effectively, and maintain direct contact with the people in the car to ensure the smooth progress of the rescue operation.

[0095] The present application uses a vehicle emergency rescue method applied to a rescue service platform, including: when receiving the MSD data sent by the vehicle-mounted platform of the target vehicle, extracting the accident information and key of the target vehicle from the MSD data; generating a plaintext control instruction, and using the key to encrypt the plaintext control instruction to obtain a ciphertext control instruction, wherein the plaintext control instruction is used to control the camera of the target vehicle; sending the ciphertext control instruction to the vehicle-mounted platform; receiving the live image sent by the vehicle-mounted platform, and generating a rescue strategy based on the live image and the accident information, so as to rescue the target vehicle according to the rescue strategy. In the event that a vehicle encounters an accident, the vehicle-mounted platform reports the MSD data and also reports the key used to control the camera of the target vehicle. The rescue service platform can control the vehicle camera to collect the live image of the scene according to the key, and then comprehensively judge the accident situation according to the live image and the MSD data, and formulate a targeted rescue plan. It solves the problem that the rescue center cannot make a comprehensive and accurate judgment of the accident scene based on the MSD data alone.
