Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to an emergency rescue method, apparatus, vehicle, and storage medium. Background Technology

[0002] In related technologies, vehicles typically trigger an emergency call (eCall) when an accident occurs. An emergency call refers to the vehicle sending a distress signal to a rescue platform when an accident happens, thereby effectively shortening rescue time and providing effective medical assistance to injured parties. Therefore, how to better send distress signals to rescue platforms to achieve emergency rescue is a pressing technical problem that needs to be solved. Summary of the Invention

[0046] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0053] Figure 6 This is a functional block diagram of a vehicle illustrating an exemplary embodiment. Detailed Implementation

[0054] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0055] In the description of this disclosure, terms such as "first" and "second" are used to distinguish similar objects and should not be construed as indicating a specific order or sequence. Furthermore, unless otherwise stated, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same elements.

[0056] Although operations or steps are described in a specific order in the accompanying drawings in the embodiments of this disclosure, it should not be construed as requiring these operations or steps to be performed in the specific order or serial order shown, or requiring all of the shown operations or steps to be performed to obtain the desired result. In the embodiments of this disclosure, these operations or steps may be performed serially; they may be performed in parallel; or a portion of these operations or steps may be performed.

[0057] As mentioned in the background section, when a vehicle accident occurs, a communication connection can usually be established with a distress platform to enable real-time communication between the occupants of the vehicle and the distress platform, thereby shortening the accident rescue time and providing effective medical assistance to the injured. When making an emergency call, a vehicle typically sends an MSD (Minimum Set of Data) message to the server to ensure rapid rescue operations. However, existing MSD messages, in order to ensure fast transmission, usually contain limited information, resulting in rescuers being unable to obtain detailed accident scene information and leading to low rescue efficiency.

[0058] In view of this, the present disclosure provides an emergency rescue method, device, vehicle, and storage medium. When it is determined that a vehicle accident has occurred, the method acquires a first minimal dataset (MSD) information and sends the first MSD information before performing a call operation. This ensures that important information is sent in a timely manner. Furthermore, sending a second MSD information to the server after performing the call operation can assist in the rescue, thereby improving the efficiency of the rescue and ensuring the stability and timeliness of MSD information transmission.

[0059] First, the applicable scenarios of the emergency rescue method provided in the embodiments of this disclosure will be described. Figure 1 This is a schematic diagram illustrating an applicable scenario for an emergency rescue method according to an exemplary embodiment. For example... Figure 1As shown, the scenario may include vehicle 10 and a first cloud service platform 20. The first cloud service platform 20 may be an emergency assistance platform or a call center, or a remote server. Vehicle 10 has the function of establishing an emergency call connection with the first cloud service platform 20.

[0060] Figure 2 This is a flowchart illustrating an emergency rescue method according to an exemplary embodiment, such as... Figure 2 As shown, this emergency rescue method may include the following steps.

[0061] In step S210, if it is determined that a vehicle accident has occurred, the first minimum dataset (MSD) information is obtained.

[0062] In this embodiment of the disclosure, the first minimal dataset (MSD) information may include text information, which can be used to send basic accident information. Specifically, the first minimal dataset (MSD) information may be text information containing numbers and strings. The basic accident information may include vehicle information and accident information. Vehicle information may include driver information, vehicle identification, vehicle damage location, vehicle speed, vehicle direction, vehicle fuel type, number of passengers in the vehicle, and whether the vehicle's airbags have deployed. Accident information may include the time of the accident, the method of triggering the accident, the latitude and longitude information of the accident, and the severity of the accident.

[0063] For example, the vehicle identification number can be the vehicle frame number; the time of the accident can be the time of the vehicle collision; and the latitude and longitude information of the accident can be the location of the accident, that is, the location where the accident occurred.

[0064] As an optional approach, when a vehicle accident is detected, embodiments of this disclosure can acquire first minimal dataset (MSD) information. The acquisition of the first minimal dataset (MSD) information can be triggered manually or automatically. Specifically, when a vehicle accident is detected, the vehicle can automatically acquire the first minimal dataset (MSD) information. Optionally, when a user inputs a distress signal, the vehicle can acquire the first minimal dataset (MSD) information.

[0065] It should be noted that the first minimal dataset MSD information in this embodiment can also be referred to as critical MSD information. As described above, critical MSD information may include vehicle information and the latitude and longitude information of the accident occurrence. Furthermore, to ensure that the first minimal dataset MSD information can be delivered in a timely manner, the data volume of the first minimal dataset MSD information can be relatively small.

[0066] In step S220, the first minimum dataset (MSD) information is sent to the server.

[0067] Alternatively, after obtaining the first minimal dataset (MSD) information, this embodiment of the disclosure can send the first minimal dataset (MSD) information to a server. As described above, the server can be a remote server, and the vehicle can send the first minimal dataset (MSD) information to the remote server based on the data card.

[0068] In step S230, an emergency call operation is performed, and a second MSD message is sent to the server. The data size of the second MSD message is greater than the data size of the first minimum dataset MSD message.

[0069] It should be noted that steps S220 and S230 can be executed simultaneously or sequentially, and this disclosure does not limit the execution order of the two.

[0070] As an optional approach, embodiments of this disclosure may execute an emergency call operation and send second MSD information to the server. The second MSD information has a larger data volume than the first minimum dataset MSD information; that is, the second MSD information has a relatively larger data volume. In other words, the second MSD information has a larger data volume than the first minimum dataset MSD information, meaning the time required to transmit the second MSD information is greater than the time required to transmit the first minimum dataset MSD information.

[0071] In this embodiment of the disclosure, the second MSD information may include multimedia data, which is mainly used to assist rescue efforts, i.e., to facilitate timely rescue operations by rescue personnel. Specifically, the second MSD information may include multimedia data such as images and videos, wherein the images or videos may be data collected by the vehicle's image acquisition device when the vehicle accident occurs.

[0072] The image acquisition device can be a dashcam installed in the vehicle, or an auxiliary camera installed by the user according to their personal needs. After acquiring the second MSD information, the image acquisition device can store the information in the vehicle system and then send it to a remote server through the vehicle system. Here, the vehicle system can also be called an in-vehicle infotainment system (IVI).

[0073] For example, the second MSD information may include multimedia data collected by the accident process image acquisition device, or it may include facial data of the party responsible for the accident, vehicle collision details, and data from the collision scene. Sending the second MSD information to a remote server can assist rescue personnel in conducting rapid rescue operations, thereby ensuring the timeliness and reliability of the rescue.

[0074] It should be noted that the second MSD information in this embodiment can also be referred to as auxiliary MSD information. As described above, auxiliary MSD information can include multimedia data such as images and videos. Furthermore, to better assist in rescue efforts, the second MSD information has a relatively large data volume.

[0075] In this embodiment of the disclosure, when a vehicle accident is determined to have occurred, a first minimal dataset (MSD) information is first obtained. The first minimal dataset (MSD) information may include basic accident information. Based on this, the first minimal dataset (MSD) information is sent to a server. Then, an emergency call operation is performed, and a second minimal dataset (MSD) information is sent to the server. The data volume of the second minimal dataset (MSD) information is greater than that of the first minimal dataset (MSD) information. In the event of an accident, this embodiment of the disclosure not only ensures the timely transmission of important information by sending the first minimal dataset (MSD) information and the second minimal dataset (MSD) information to the server, but also better assists in rescue efforts and improves rescue efficiency.

[0076] Figure 3 This is a flowchart illustrating another emergency rescue method according to an exemplary embodiment, such as... Figure 3 As shown, this emergency rescue method may include the following steps.

[0077] In step S310, if it is determined that a vehicle accident has occurred, the first minimum dataset (MSD) information is obtained.

[0078] As described above, the vehicle may include an in-vehicle system. In the event of a vehicle accident, this embodiment of the disclosure can detect whether the in-vehicle system supports dual SIM cards. If the in-vehicle system is determined to support dual SIM cards, this embodiment of the disclosure can separately determine whether each of the dual SIM cards supports emergency calls under IMS (IP Multimedia Subsystem). Here, the dual SIM cards may include a first SIM (Subscriber Identity Module) card and a second SIM card.

[0079] Specifically, this embodiment of the disclosure can detect whether each SIM card in the vehicle system is registered with IMS. If it is determined that the SIM card is registered with IMS, the vehicle can determine whether the corresponding SIM card supports emergency calls under IMS based on the first system message and the second system message it receives. Here, the SIM card corresponding to the first system message can be the first SIM card, and the SIM card corresponding to the second system message can be the second SIM card. That is, the first system message can be received based on the first SIM card, and the second system message can be received based on the second SIM card.

[0080] As an example, if the vehicle determines that the first system message received based on the first SIM card carries IMS-EmergencySupport information, it can determine that the first SIM card supports IMS emergency calls; otherwise, it can determine that the first SIM card does not support IMS emergency calls.

[0081] As another example, if the vehicle determines that the second system message received based on the second SIM card carries IMS-EmergencySupport information, it can be determined that the second SIM card supports IMS emergency calls; otherwise, it can be determined that the second SIM card does not support IMS emergency calls.

[0082] As an alternative approach, after determining that the vehicle supports dual SIM cards and separately determining whether each SIM card supports IMS emergency calls, if it is determined that at least one of the dual SIM cards supports IMS emergency calls, the embodiments of this disclosure can obtain a first user identification card, which can be used to perform an emergency call operation.

[0083] Specifically, when one of the dual SIM cards supports IMS emergency calls, this embodiment of the disclosure can use the card that supports IMS emergency calls as the first user identification card (SIM card), and the card that does not support IMS emergency calls as the second user identification card (SIM card). Based on this, the emergency call operation is performed using the first SIM card. For example, when it is determined that the first SIM card supports IMS emergency calls, the first SIM card can be used as the first user identification card.

[0084] Optionally, when both SIM cards support emergency calls under IMS, this embodiment of the disclosure can select either SIM card as the first user identification card and use the first user identification card to perform the emergency call operation. For example, the primary SIM card can be used as the first user identification card. For example, when both the first SIM card and the second SIM card support emergency calls under IMS, the primary SIM card can be used as the first user identification card.

[0085] Optionally, when neither SIM card supports emergency calls under IMS, this embodiment of the present disclosure may select a first user identification card from the two SIM cards and use the first user identification card to send the first minimum data set (MSD) information, and perform an emergency call operation based on the first user identification card. For example, when neither the first SIM card nor the second SIM card supports emergency calls under IMS, the primary SIM card can be used as the first user identification card.

[0086] In step S320, the first minimum dataset (MSD) information is sent to the server.

[0087] As a specific implementation, when it is determined that one SIM card supports IMS emergency calls while the other does not, this embodiment of the disclosure can determine whether the two SIM cards support dual SIM dual active (DSDA) functionality. If it is determined that the two SIM cards support dual SIM dual active functionality, the first minimum data set (MSD) information is sent to the server based on the second user identification card. At this time, if the second user identification card is the default data card, this embodiment of the disclosure can directly use the second user identification card to send the first minimum data set (MSD) information to the server.

[0088] Optionally, when it is determined that one of the dual SIM cards supports IMS emergency calls while the other does not, if it is determined that the dual SIM cards do not support dual-SIM dual-pass functionality, and the default data card is the second user identification card, this embodiment of the disclosure can switch the data card from the second user identification card to the first user identification card. Based on this, the first minimum data set (MSD) information is sent to the server using the first user identification card.

[0089] It should be noted that when it is determined that one of the dual SIM cards supports IMS emergency calls while the other does not, if the default data card is determined to be the first user identification card, then this embodiment of the present disclosure can directly use the first user identification card to send the first minimum data set (MSD) information, and perform an emergency call operation based on the first user identification card, and send the second MSD information.

[0090] In summary, when it is determined that one of the dual SIM cards supports IMS emergency calls, this embodiment of the present disclosure can first send the first minimal dataset MSD information (critical MSD information) to a remote server via a data link before making an emergency call. As described above, the first minimal dataset MSD information does not contain multimedia data such as images / videos, in order to prioritize the transmission of vehicle information, accident location latitude and longitude information, etc. Based on this, an emergency call under IMS is made, and second MSD information (auxiliary MSD information) can be transmitted during the call.

[0091] As another specific implementation, when it is determined that both SIM cards support IMS emergency calls, this embodiment of the disclosure can select either SIM card as the first user identification card and use the first user identification card to send the first minimum data set (MSD) information to the server. For example, the primary SIM card can be used as the first user identification card.

[0092] In this process, embodiments of this disclosure can obtain the quality of the data link corresponding to the first user identification card, where the default data card is the first user identification card. Based on this, it is determined whether the quality of the data link meets preset conditions. If it is determined that the quality of the data link meets the preset conditions, embodiments of this disclosure can send the first minimum dataset (MSD) information to the server through the first user identification card.

[0093] Optionally, if it is determined that the quality of the data link corresponding to the first user identification card does not meet the preset conditions, this embodiment of the disclosure can switch the data card from the first user identification card to the second user identification card, and send the first minimum dataset (MSD) information to the server through the second user identification card.

[0094] Here, when determining whether the quality of the data link corresponding to the first user identification card meets the preset conditions, this embodiment of the disclosure can obtain a first transmission duration, wherein the first transmission duration can be the time consumed by sending the first minimum data set (MSD) information using the first user identification card. When it is determined that the first transmission duration exceeds the preset duration, this embodiment of the disclosure can determine that the quality of the data link corresponding to the first user identification card meets the preset conditions.

[0095] In this embodiment of the disclosure, the preset duration can be an empirical value of the time required to transmit MSD information under normal circumstances, and the preset duration can be dynamically updated. For example, the historical transmission time of MSD information can be obtained, the average transmission time can be obtained based on the historical transmission time, and the average transmission time can be used as the preset duration. Optionally, the preset duration can also be determined according to the vehicle's service life. For example, in the first ten years after the vehicle is manufactured, the preset duration can be 10 seconds, and in the last ten years after the vehicle is manufactured, the preset duration can be updated to 20 seconds.

[0096] Optionally, the preset duration can also be determined based on the number of accidents involving the vehicle; the more accidents a vehicle has, the shorter the preset duration can be. Optionally, the preset duration can also be determined based on the region where the vehicle is located; different regions will have different preset durations. For example, if the probability and risk of a collision are high in region 1, the preset duration can be longer. How the preset duration is dynamically adjusted is not explicitly limited here and can be selected based on actual circumstances.

[0097] As an example, if both SIM cards support emergency calls under IMS, and it is detected that one SIM card takes N seconds (a preset duration) to complete transmitting critical MSD information, it can be determined that the data link quality for that SIM card is poor. In this case, the other SIM card can be switched to for transmission, and after transmission is complete, either SIM card can be selected for the emergency call. Here, N seconds can be an empirical value representing the normal transmission time for MSD information and can be dynamically updated.

[0098] As another specific implementation, when it is determined that neither SIM card supports IMS emergency calls, this embodiment of the disclosure can select either SIM card as the first user identification card. For example, the primary SIM card can be used as the first user identification card. Based on this, the first minimum data set (MSD) information is sent to the server based on the first user identification card, and the emergency call operation is performed based on the first user identification card.

[0099] In step S330, an emergency call operation is performed based on the first user identification card, and the second MSD information is sent to the server.

[0100] As a specific implementation, when it is determined that at least one of the dual SIM cards supports IMS emergency calls, this embodiment of the disclosure can perform an emergency call operation based on the first user identification card after sending the first minimal dataset (MSD) information to the server, and send the second MSD information to the server during the call or after the call ends. It should be noted that the user identification card sending the first and second MSD information can be the same.

[0101] As a specific implementation, when it is determined that neither SIM card supports IMS emergency calls, after obtaining the first user identification card, this embodiment of the present disclosure can first use the first user identification card to send the first minimum data set (MSD) information to the server. After the transmission of the first MSD information is completed, this embodiment of the present disclosure can initiate circuit-switched fallback based on the first user identification card and perform an emergency call operation. Furthermore, after the call ends, this embodiment of the present disclosure can send the second MSD information to the server based on the first user identification card.

[0102] Optionally, if neither SIM card supports IMS emergency calls, and one SIM card is selected as the first user identification card (SIM card) and the first minimum data set (MSD) information is sent to the server using the first SIM card, this embodiment of the present disclosure can also use the other SIM card as the second SIM card. Based on this, circuit-switched fallback is initiated using the second SIM card, and an emergency call operation is performed. After the call ends, this embodiment of the present disclosure can send the second MSD information to the server using the second SIM card. Whether the emergency call operation is performed using the second SIM card is not explicitly limited and can be selected according to the actual situation.

[0103] As an example, if it is determined that neither SIM card supports emergency calls under IMS, then when initiating a call after a collision, critical MSD information is first transmitted to the server via the data link. Furthermore, after the critical MSD transmission is complete, the vehicle can initiate circuit-switched fallback to make an emergency call. After the call ends, embodiments of this disclosure can optionally continue transmitting auxiliary MSD information.

[0104] As an optional approach, if an emergency call fails during the execution of an emergency call operation, this embodiment of the disclosure can record the number of call failures corresponding to that SIM card. Specifically, if an emergency call operation fails based on either of the two SIM cards, the number of failures is recorded, and if the number of failures exceeds a preset number, an emergency call operation is performed based on the other SIM card. For example, if an emergency call fails more than M times on one SIM card, the other SIM card is used for a retry.

[0105] To better illustrate the specific procedures for emergency rescue, the embodiments disclosed herein provide, as follows: Figure 4 The example diagram is shown below. (By...) Figure 4 It is understood that this embodiment can detect whether the vehicle system supports dual SIM cards and determine whether both SIM cards are registered with IMS. If it is determined that only one SIM card supports IMS emergency calls, this embodiment can use that SIM card when making an emergency call, and the data card can also be switched to that SIM card. It should be noted that if only one SIM card supports IMS emergency calls, this embodiment can transmit key MSD information before making an emergency call, and then perform the IMS emergency call while simultaneously transmitting auxiliary MSD information.

[0106] Optionally, through Figure 4 Knowing that neither SIM card supports emergency calls under IMS, this embodiment of the present disclosure can first transmit key MSD information to the server via a data link, then make an emergency call, and transmit auxiliary MSD information after the call ends.

[0107] Furthermore, if it is determined that both SIM cards support emergency calls under IMS, this embodiment can first transmit the critical MSD information to the server via the data link for N seconds. If the transmission is still not complete, it can switch to the other SIM card for transmission. After the transmission is complete, an emergency call is made, and auxiliary MSD information is sent to the server. It should be noted that if one SIM card fails to make an emergency call M times, this embodiment can use the other SIM card to retry.

[0108] It should be noted that the second Minimal Data Set (MSD) information sent by the vehicle to the server may also include image or video data of the vehicle's environment. After sending this information to the server, the server can be instructed to combine the first minimum dataset (MSD) information and the second MSD information to determine whether the vehicle is in a specified scenario. For example, based on the accident's location information and image and video data, it can be determined whether the vehicle is in a specified scenario. If it is determined that the vehicle is in a specified scenario, the vehicle can receive a self-rescue signal from the server and activate its self-rescue device based on that signal.

[0109] As an example, the specified scenario may include a water-falling scenario. Upon receiving a self-rescue signal, the vehicle can activate the water rescue device based on the self-rescue signal. Once activated, the rescue device can make the vehicle float to facilitate breathing for the passengers.

[0110] As another example, the specified scenario could include a collision and fire scenario. Upon receiving a self-rescue signal, the vehicle could activate a voice prompt device based on the signal and adjust the volume of the voice prompt device to the maximum to remind passengers to leave the vehicle as soon as possible, otherwise there is a risk of explosion.

[0111] This disclosure allows for determining which SIM card to use for MSD data transmission based on the vehicle's dual-SIM card support for IMS emergency calls, and also allows determining which SIM card to use for emergency calls based on the number of failed emergency calls. Furthermore, this disclosure can also determine the timing of transmitting critical MSD information and auxiliary MSD information based on the status of the vehicle's dual SIM cards. This ensures timely transmission of MSD information when dialing emergency numbers in a dual-SIM scenario, maximizing the timeliness of emergency calls and MSD information transmission.

[0112] In this embodiment of the present disclosure, when a vehicle accident is determined to have occurred, a first minimal dataset (MSD) information is first obtained. This first MSD information may include basic accident information. Based on this, the first MSD information is sent to a server. Then, an emergency call operation is executed, and a second MSD information is sent to the server. The second MSD information has a larger data volume than the first MSD information. In the event of an accident, this embodiment of the present disclosure, by sending both the first and second MSD information to the server, not only ensures the timely delivery of important information but also better assists in rescue efforts, thereby improving rescue efficiency. Furthermore, this embodiment of the present disclosure, through hierarchical transmission of MSD information, ensures that the transmission of critical MSD information is completed before the emergency call is dialed.

[0114] The acquisition module 510 is configured to acquire first minimum dataset (MSD) information when it is determined that a vehicle accident has occurred. The first minimum dataset (MSD) information includes text information for sending basic information about the accident.

[0115] The sending module 520 is configured to send the first minimum dataset (MSD) information to the server.

[0116] The call module 530 is configured to perform an emergency call operation and send a second MSD message to the server. The second MSD message has a larger data volume than the first minimum dataset MSD message. The second MSD message includes multimedia data for assisting rescue efforts.

[0117] In some embodiments, the emergency rescue device 500 may further include:

[0118] The identification card acquisition module is configured to acquire a first user identification card when it is determined that the vehicle supports dual cards and at least one of the dual cards supports emergency calls via Internet Protocol Multimedia Subsystem (IMS), wherein the first user identification card is used to perform the emergency call operation.

[0119] In some implementations, when one of the dual SIM cards supports emergency calls via IMS, the card that supports emergency calls via IMS is designated as the first user identification card, and the card that does not support emergency calls via IMS is designated as the second user identification card.

[0120] In some implementations, the sending module 520 may also be configured to send the first minimum data set (MSD) information to the server based on the second user identification card when it is determined that the dual cards support dual-card dual-pass.

[0121] In some implementations, the sending module 520 may also be configured to switch the data card from the second user identification card to the first user identification card when it is determined that the dual cards do not support dual-card dual-pass, and send the first minimum dataset (MSD) information to the server based on the first user identification card.

[0122] In some implementations, the identification card acquisition module may also be configured to select one of the two cards as the first user identification card when both cards support emergency calls via the IMS.

[0123] In some implementations, the sending module 520 may also be configured to acquire the quality of the data link corresponding to the first user identification card; when the quality of the data link meets a preset condition, the first minimum data set (MSD) information is sent to the server via the first user identification card.

[0124] In some implementations, the sending module 520 may also be configured to switch the data card from the first user identification card to a second user identification card when the quality of the data link does not meet preset conditions, and send the first minimum dataset (MSD) information to the server through the second user identification card.

[0125] In some implementations, the quality of the data link meets preset conditions, including: a first transmission duration exceeding a preset duration, wherein the first transmission duration is the time consumed by sending the first minimum data set (MSD) information through the first user identification card.

[0126] In some implementations, the identification card acquisition module may also be configured to select the first user identification card from the two cards when it is determined that neither of the two cards supports the emergency call of the IMS; the sending module 520 may also be configured to send the first minimum data set (MSD) information to the server based on the first user identification card; the calling module 530 may also be configured to perform circuit-switched fallback based on the first user identification card and execute the emergency call operation; and send the second MSD information to the server based on the first user identification card.

[0127] In some implementations, the call module 530 may also be configured to record the number of failures if the emergency call operation fails to be performed based on either of the two SIM cards; and to perform the emergency call operation based on the other SIM card when the number of failures exceeds a preset number.

[0128] In this embodiment of the disclosure, when a vehicle accident is determined to have occurred, a first minimal dataset (MSD) information is first obtained. The first minimal dataset (MSD) information may include basic accident information. Based on this, the first minimal dataset (MSD) information is sent to a server. Then, an emergency call operation is performed, and a second minimal dataset (MSD) information is sent to the server. The data volume of the second minimal dataset (MSD) information is greater than that of the first minimal dataset (MSD) information. In the event of an accident, this embodiment of the disclosure not only ensures the timely transmission of important information by sending the first minimal dataset (MSD) information and the second minimal dataset (MSD) information to the server, but also better assists in rescue efforts and improves rescue efficiency.
