[0028] In order to make the personnel in the technical field better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0029] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] According to the embodiments of the present application, a method embodiment of controlling a vehicle is provided. It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown herein.

[0031] In the present embodiment, a method for controlling a vehicle is provided, Figure 1 is a flowchart of a method for controlling a vehicle according to an embodiment of the present application, as Figure 1 shown, the flow includes the following steps:

[0032] Step S101, in response to the concentration of the preset type gas inside the vehicle being greater than the preset concentration threshold, determining the control strategy of the vehicle to be a first control strategy and / or a second control strategy.

[0033] In the technical solution provided in step S101 of the present application, the preset type gas is used to indicate a gas affecting the health condition of at least one occupant in the vehicle, for example, a harmful gas threatening the health of the occupant, such as carbon monoxide (CO). The primary control strategy is used to indicate a rule for adjusting the concentration of the preset type gas in the vehicle. When the concentration of the preset type gas in the vehicle is greater than a preset concentration threshold, the primary control strategy can be used to reduce the concentration of the preset type gas in the vehicle to quickly improve the air quality in the vehicle and reduce the health threat of the preset type gas to the occupant. The secondary control strategy is used to indicate a rule for triggering a warning operation of the vehicle, which aims to send warning information to the inside and outside of the vehicle through a multi-modal warning mode to prompt that there is a risk of exceeding the harmful gas concentration in the vehicle at present.

[0034] In this embodiment, the gas sensors deployed in multiple areas (such as the driver's cabin, rear seats, air conditioning ducts, etc.) of the vehicle can continuously detect the type and concentration of the gas in the vehicle. When the concentration of the preset type gas in the vehicle is detected to be greater than a preset concentration threshold through the multiple gas sensors, the primary control strategy can be triggered immediately to control the vehicle, wherein the preset concentration threshold is usually set to 100 ppm, which is only an example and does not limit the specific value of the preset concentration threshold.

[0035] Optionally, the primary control strategy is mainly used to reduce the concentration of the preset type gas in the vehicle to quickly improve the air quality in the vehicle and reduce the direct health threat to the occupants. The primary control strategy can at least include a ventilation strategy and a gas replacement strategy, wherein the priority of the ventilation strategy is higher than that of the gas replacement strategy, and the use of the ventilation strategy needs to be triggered when the current environment of the vehicle meets the use condition of the ventilation strategy.

[0036] Optionally, before executing the primary control strategy, the environmental information of the current environment of the vehicle can be detected, and then it is determined whether the current environment of the vehicle meets the use condition of the ventilation strategy in the primary control strategy according to the environmental information of the current environment of the vehicle. If the current environment of the vehicle meets the use condition of the ventilation strategy, the vehicle is controlled to execute the ventilation strategy to reduce the concentration of the preset type gas in the vehicle. If the current environment of the vehicle does not meet the use condition of the ventilation strategy, the vehicle is controlled to execute the gas replacement strategy.

[0037] Optionally, if the vehicle is currently in a closed state, and the current environment of the vehicle is a non-extreme weather condition, it is determined that the vehicle currently satisfies the use condition of the ventilation strategy, wherein the non-extreme weather condition is used to indicate that the current environment of the vehicle is not raining, or the vehicle is not wading. When controlling the vehicle to execute the ventilation strategy, the vehicle can be controlled to automatically open the windows and / or sunroof to introduce fresh air to dilute the concentration of the preset type of gas in the vehicle interior.

[0038] Optionally, if the vehicle is currently in a closed state, but the current environment of the vehicle is an extreme weather condition, it is determined that the vehicle currently does not satisfy the use condition of the ventilation strategy. In this case, the vehicle can be controlled to execute a gas replacement strategy, wherein the gas replacement strategy can reduce the concentration of the preset type of gas in the vehicle interior by delivering target inert gas and oxygen into the vehicle interior.

[0039] Optionally, the secondary control strategy is a multi-modal early warning and emergency communication mechanism activated when the primary strategy fails to immediately reduce the concentration of the preset type of gas in the vehicle interior for a duration exceeding a threshold. The secondary control strategy can be executed synchronously with the primary control strategy, asynchronously with the primary control strategy, or only one of the primary control strategy or the secondary control strategy, without specific limitation here.

[0040] Optionally, upon detecting that the concentration of the preset type of gas in the vehicle interior is greater than a preset concentration threshold, the secondary control strategy can be triggered, wherein the secondary control strategy includes a local early warning strategy and a remote early warning strategy. The local early warning strategy, also known as an in-vehicle early warning strategy, can alert the occupants in the vehicle interior through a multi-modal early warning method, such as displaying red warning information on the vehicle screen, vibrating the seat to wake up the occupants who may have fallen into a coma, and providing early warning information through voice broadcast, so that the occupants in the vehicle interior can take self-rescue measures after receiving the multi-modal early warning information. At the same time, the remote early warning strategy can be used to send early warning information to the outside of the vehicle to request rescue from the outside of the vehicle. For example, the early warning information with the vehicle location and gas concentration change information can be automatically sent to the communication terminal of the emergency contact associated with the vehicle, and the rescue information can be directly sent to the emergency center through the vehicle-mounted telematics box (T-box), and the vehicle identification information and the health records of the occupants can be synchronously uploaded to enable the rescue personnel to quickly understand the vehicle situation.

[0041] Optionally, the secondary control strategy aims to ensure that in the case where the concentration of the preset type of gas in the vehicle interior cannot be reduced in time, the affected occupants can also be awakened in time through a multi-modal early warning method to take necessary self-rescue measures, and a rescue signal can be sent to the outside of the vehicle to quickly obtain rescue resources.

[0042] In this step, through the sensors and control logic built-in the vehicle, the automation from gas concentration monitoring to emergency response is realized, and through the hierarchical control strategy, the technical effect of effectively solving the safety of the driver and passenger when the harmful gas concentration in the vehicle is increased is realized, and the active safety protection ability of the vehicle in emergency is realized.

[0043] In step S102, according to the first-level control strategy and / or the second-level control strategy, in the process of controlling the vehicle, in response to the time period during which the concentration of the preset type gas is greater than the preset concentration threshold value exceeding the preset time period, and the driver and passenger in the vehicle being in a non-response state, the control strategy is switched from the first-level control strategy and / or the second-level control strategy to the third-level control strategy.

[0044] In the technical solution provided in the above step S102 of the present application, the non-response state is used to indicate that the driver and passenger in the vehicle cannot independently perform operation behavior under the influence of the preset type gas, that is, the driver and passenger lose consciousness due to gas poisoning or other health condition deterioration. The third-level control strategy is used to indicate the rules for triggering the driving first-aid mode of the vehicle, and the driving first-aid mode is used to at least indicate that the vehicle is navigated to a target first-aid place to realize the safety of the driver and passenger in the vehicle through the vehicle itself.

[0045] In this embodiment, as introduced in the foregoing step S101, in the initial stage of detecting that the concentration of the preset type gas in the vehicle is greater than the preset concentration threshold value, the first-level control strategy is triggered to reduce the concentration of the preset type gas in the vehicle, and the second-level control strategy is triggered to perform in-vehicle multi-modal early warning and send an alarm to the emergency contact and the first-aid center. These strategies aim to quickly reduce the gas concentration while informing relevant personnel of the emergency. However, if the control system of the vehicle continuously detects that the concentration of the preset type gas is greater than the preset concentration threshold value for a time period exceeding the preset time period, and confirms that the driver and passenger in the vehicle are in a non-response state, that is, the driver and passenger cannot independently perform any operation behavior (this may be because the driver and passenger lose consciousness due to gas poisoning or other health condition deterioration), in this case, it is determined that the current condition of the vehicle has exceeded the range that can be handled by the first-level and second-level control strategies, and more urgent and direct action is needed. Based on this, the control system of the vehicle can switch the control strategy of the vehicle from the first-level control strategy and / or the second-level control strategy to the third-level control strategy. The core of the third-level control strategy is to activate the driving first-aid mode to navigate the vehicle to the nearest first-aid place, and to maximize the safety of the driver and passenger in the vehicle by seeking help from the outside world.

[0046] Optionally, the final goal of the three-level control strategy is to safely and quickly send the passengers to a professional medical institution in case of loss of consciousness and inability to self-rescue, to minimize health damage caused by excessive harmful gas concentration, and to save lives through the highly automated emergency handling capability of the vehicle itself.

[0047] In step S103, the vehicle is controlled to drive to the target first-aid site according to the three-level control strategy.

[0048] In the technical solution provided by step S103 of the present application, the three-level control strategy can include enabling the automatic auxiliary driving navigation (Navigate on Autopilot, NOA for short) function of the vehicle, and automatically planning the optimal path to the nearest target first-aid site according to the current vehicle location information and road conditions. In this process, the vehicle will try to avoid congested sections and traffic restriction areas to ensure a quick and safe arrival at the destination, where the target first-aid site can be a first-aid center, a hospital, an emergency room, etc.

[0049] In this embodiment, after detecting that the control strategy of the vehicle is switched to the three-level control strategy, the driving first-aid mode of the vehicle can be triggered according to the three-level control strategy to control the vehicle to drive to the target first-aid site.

[0050] Optionally, during the driving of the vehicle to the target first-aid site through automatic auxiliary navigation, the vehicle can also send a priority passage request to the traffic signal control system along the way through vehicle-to-everything (V2X) communication technology, strive to obtain a green light passage, reduce the time waiting for a red light during driving, and speed up the rescue process.

[0051] Optionally, during the driving of the vehicle to the target first-aid site through automatic auxiliary navigation, the vehicle can also use an external directional loudspeaker to play prompt information, for example, the content of the prompt information can be "this vehicle is performing a first-aid task, please other vehicles to give way", to ensure that surrounding vehicles and pedestrians understand the situation and actively give way to the vehicle, creating an unobstructed traffic environment for the vehicle.

[0052] Optionally, during the driving of the vehicle to the target first-aid site through automatic auxiliary navigation, the vehicle can also interact with the first-aid linkage cloud platform through the vehicle-mounted T-Box, automatically dial the first-aid center phone, report the specific situation (such as vehicle location, in-vehicle personnel status, gas concentration data), and start the medical resource scheduling program, including but not limited to the preparation of the first-aid center for reception, the deployment of ambulances along the way, etc. The medical team and necessary rescue equipment are ready for use, and can immediately start rescue work.

[0053] In this step, the automatic driving capability of the vehicle and the efficient scheduling of external resources are utilized to provide emergency rescue services for the passengers in danger, and the vehicle is automatically navigated to the nearest emergency treatment site without manual operation, thereby minimizing health damage and improving survival rate.

[0054] In the above steps S101 to S103 of the present application, for the case of abnormal concentration of a preset type of gas in the vehicle, a multi-level control strategy is set to control the vehicle to effectively protect the health of the passengers in the vehicle. Specifically, when the concentration of the preset type of gas in the vehicle is detected to be greater than the preset concentration threshold, a first-level control strategy can be triggered to reduce the concentration of the preset type of gas in the vehicle, and a second-level control strategy can be triggered for early warning. In this process, if the concentration of the preset type of gas in the vehicle is detected to be greater than the preset concentration threshold for a time period exceeding a preset time period, and the passengers in the vehicle are in a non-responsive state, it indicates that the concentration of the preset type of gas in the vehicle has not been reduced, and the passengers in the vehicle may have lost consciousness. In this case, the first-level control strategy and / or the second-level control strategy can be quickly switched to a third-level control strategy, and then the vehicle is navigated to a target emergency treatment site according to the third-level control strategy to rescue the passengers in the vehicle. That is, in the present application, by setting a multi-level control strategy, rapid response, effective control and comprehensive rescue of passengers in the vehicle are achieved when the concentration of the preset type of gas in the vehicle is abnormal, thereby effectively improving the emergency handling capability of the vehicle in the face of emergency situations such as excessive concentration of the preset type of gas in the vehicle, and providing comprehensive and efficient safety protection for the passengers in the vehicle, thereby solving the technical problem that the harmful gas of the preset type in the vehicle cannot be effectively removed to affect the passengers in the vehicle in the related art.

[0055] The above vehicle control method of the present application will be further described below.

[0056] As an optional implementation, the first-level control strategy at least includes a ventilation strategy and / or a gas replacement strategy, the ventilation strategy is used to indicate a rule for controlling the vehicle to open the windows and / or the sunroof, the gas replacement strategy is used to indicate a rule for triggering an inert gas release device on the vehicle to release a target inert gas into the vehicle, and the priority of the ventilation strategy is higher than the priority of the gas replacement strategy. In step S102, the vehicle is controlled according to the first-level control strategy, including: detecting environmental information of an environment in which the vehicle is currently located; in response to the environmental information satisfying a use condition of the ventilation strategy, determining that the control strategy of the vehicle is the ventilation strategy, wherein the use condition is used to indicate that the environment in which the vehicle is currently located is a non-extreme weather condition; and in response to the environmental information not satisfying the use condition of the ventilation strategy, determining that the control strategy of the vehicle is the gas replacement strategy.

[0057] In this embodiment, in the emergency handling system of the vehicle, the first-level control strategy is a preliminary response to the increase in the concentration of a preset type of gas, mainly including a ventilation strategy and a gas replacement strategy. The purpose of these two strategies is to quickly reduce the concentration of harmful gases in the vehicle to ensure the safety of the driver and passengers. However, when executing, the optimal choice can be made according to the environmental information of the vehicle to adapt to various actual scenarios and ensure the effectiveness and safety of the strategy.

[0058] Optionally, since window ventilation can quickly reduce the concentration of harmful gases in a closed environment, the priority of the ventilation strategy in the first-level control strategy is higher than that of the gas replacement strategy. This means that if the current environment of the vehicle meets the use conditions of the ventilation strategy, the ventilation strategy will be preferred because this way is relatively simple, low cost, and can effectively introduce fresh air to quickly reduce the concentration of the preset type of gas in the vehicle. Only when the use conditions of the ventilation strategy are not met, can the relatively complex gas replacement strategy be used, that is, to dilute harmful gases by releasing inert gases (such as nitrogen) while avoiding the introduction of external air quality that may be harmful to the driver and passengers.

[0059] For example, when the concentration of the preset type of gas inside the vehicle is detected to be greater than the preset concentration threshold, the environmental information of the current environment of the vehicle is first detected to determine whether the current environment of the vehicle meets the use conditions of the ventilation strategy. The environmental information of the current environment of the vehicle includes but is not limited to weather conditions, whether the vehicle is involved in water or whether there are other safety hazards outside the vehicle, etc. These information is crucial for evaluating whether the ventilation strategy can be safely executed.

[0060] Optionally, if the environmental information indicates that the vehicle is located in a non-extreme weather condition, i.e., there is no adverse weather such as heavy rain, snow, sandstorm, etc., and there is no special situation such as water involvement, it can be determined that the current environment of the vehicle meets the use conditions of the ventilation strategy, and in this case, the ventilation strategy can be executed to safely open the windows or sunroof to achieve effective ventilation. The ventilation strategy is particularly suitable for CO concentration increase problems in most daily driving scenarios, such as short-term engine failure or CO accumulation during idling.

[0061] Optionally, if the environmental information does not meet the use condition of the ventilation strategy, for example, the vehicle is involved in water and cannot open the window, or the external environment is extreme (such as heavy rain, and the window cannot be opened), in this case, the gas replacement strategy can be used to deliver inert gas or oxygen to the vehicle interior to reduce the concentration of the preset type gas in the vehicle interior. The gas replacement strategy is usually applied in extreme conditions, such as the vehicle is involved in water, heavy rain, and the window cannot be opened. By replacing the inert gas (such as nitrogen), a relatively safe breathing environment is created, effectively isolating harmful gases while avoiding additional threats to people inside the vehicle caused by external harsh conditions.

[0062] In the above manner, the emergency handling system of the vehicle can flexibly cope with various situations, preferentially adopts natural ventilation to reduce the concentration of the preset type gas in the vehicle interior, which is both economical and efficient; and when necessary, provides emergency life support through the gas replacement strategy to ensure the safety of personnel in extreme environments. This multi-level and adaptive strategy design reflects the intelligence of the vehicle control system and improves the flexibility and effectiveness of coping with poisoning events of the preset type gas.

[0063] As an optional implementation, the vehicle is controlled according to the gas replacement strategy, including: triggering the inert gas release device according to the gas replacement strategy to release the target inert gas into the vehicle interior; and controlling the oxygen-providing regeneration module on the vehicle to generate oxygen and deliver the oxygen to the vehicle interior according to the gas replacement strategy.

[0064] In this embodiment, when the vehicle is controlled using the gas replacement strategy, the inert gas and oxygen can be injected into the vehicle interior through the inert gas release device on the vehicle and the oxygen-providing regeneration module on the vehicle to reduce the concentration of the preset type gas in the vehicle interior.

[0065] Optionally, the vehicle is pre-equipped with an inert gas device, so that when the vehicle is controlled according to the gas replacement strategy, the inert gas release device in the vehicle can be started to release the target inert gas into the vehicle interior, wherein the target inert gas is preferably high-pressure nitrogen. Nitrogen is a colorless, odorless, and non-flammable inert gas that can rapidly dilute the concentration of harmful gases in the vehicle after being released in large quantities to form a relatively safe breathing environment. This is only an exemplary example and does not limit the type of inert gas.

[0066] Optionally, while reducing the concentration of the preset type of gas in the vehicle, it is also necessary to ensure that the oxygen content in the vehicle is maintained at a safe level to prevent personnel from being harmed due to lack of oxygen. Based on this, an oxygen supply regeneration module can also be triggered to deliver oxygen to the interior of the vehicle. For example, the oxygen supply regeneration module usually includes a vehicle-mounted electrolytic water oxygen generation device. When the gas replacement strategy takes effect, the vehicle power supply will be automatically adjusted to supply power to the electrolytic water device to generate oxygen by electrolyzing water molecules, which is then delivered to the interior of the vehicle.

[0067] Optionally, the oxygen generated by the oxygen supply regeneration module can be delivered to the vehicle cabin through the vehicle's air conditioning system or a dedicated oxygen delivery pipeline, not only to offset the decrease in oxygen content caused by the release of nitrogen, but also to further optimize the air composition in the vehicle to provide necessary life support for the occupants. In particular, in the case where the occupants may lose consciousness due to poisoning by harmful gases, sufficient oxygen supply is crucial to help alleviate the symptoms of poisoning and gain time for subsequent medical assistance.

[0068] In this step, the execution of the gas replacement strategy includes two important operations: one is to dilute and reduce the concentration of harmful gases by releasing inert gases such as nitrogen, and the other is to generate oxygen by the oxygen supply regeneration module to maintain a suitable oxygen level in the vehicle. The organic combination of these two operations ensures the breathing safety of the occupants in extreme environmental conditions.

[0069] As an optional implementation, the secondary control strategy at least includes a local warning strategy and a remote warning strategy. The local warning strategy at least includes seat vibration warning, voice broadcast warning, and instrument pop-up warning. The remote warning strategy is used to indicate the position information of the current location of the vehicle and the concentration change curve of the preset type of gas in the vehicle interior, and send the information to the emergency communication equipment of the vehicle, and trigger the vehicle-mounted information processing device of the vehicle to send warning information to the outside world. In step S102, the vehicle is controlled according to the secondary control strategy, including: triggering the local warning device in the vehicle to execute the local warning strategy and triggering the remote warning device of the vehicle to execute the remote warning strategy according to the secondary control strategy.

[0070] In this embodiment, while reducing the concentration of the preset type of gas in the vehicle by the primary control strategy, the secondary control strategy can also be used to send warning information to ensure that the occupants can timely learn and respond, and also quickly notify the outside world for help.

[0071] Optionally, the secondary control strategy at least includes a local early warning strategy and a remote early warning strategy. The local early warning strategy can remind the driver and passengers in the vehicle through a multi-modal early warning method, which at least includes seat vibration warning, voice broadcast warning, and instrument pop-up warning. Seat vibration warning triggers the built-in vibration device of the seat to produce strong vibration. This non-auditory warning method is used to awaken the driver and passengers who may be in a coma or semi-coma state due to gas poisoning, especially in noisy environments where sound warnings may not be noticed. Voice broadcast warning will broadcast emergency alert information to clearly inform the driver of the dangerous situation of gas leakage or concentration exceeding the standard. For example, the voice broadcast warning is: "The carbon monoxide concentration in the vehicle is abnormal, please take immediate action". The instrument pop-up warning will pop up a prominent red warning window on the instrument panel or center screen in front of the driver, and display relevant information such as "preset type gas concentration is high, pay attention to safety!" in the window, providing an intuitive visual alarm to ensure that the driver and passengers can immediately detect abnormalities while focusing on driving.

[0072] Optionally, the remote early warning strategy mainly includes sending the location information of the current location of the vehicle, the concentration change curve of the preset type gas inside the vehicle, to the emergency communication equipment of the vehicle, and triggering the vehicle's on-board information processing device to send warning information to the outside world. For example, through the vehicle's T-Box, the accurate location information of the vehicle and the curve graph of the change of the gas concentration in the vehicle over time are sent to the pre-set emergency communication equipment, such as the mobile terminal of the emergency contact person, the command center of the rescue agency, etc. These information is crucial for evaluating the on-site situation and developing rescue plans, especially the concentration curve can help rescue personnel predict the gas diffusion trend and better prepare rescue equipment.

[0073] Optionally, the remote early warning strategy can also include sending warning information to the outside world. For example, the vehicle's on-board information processing device, i.e. T-Box, will automatically trigger the emergency call (E-call) function after receiving the danger signal, and send detailed warning information including the vehicle identification number (VIN), the health records of the driver and passengers, and the above-mentioned location information and gas concentration data to the customer service center or rescue agency. The purpose of this is to ensure that the rescue party can quickly identify the vehicle identity, understand the basic condition of the people in the vehicle, and timely carry out targeted rescue actions.

[0074] For example, when the secondary control strategy is triggered, the vehicle will simultaneously execute both the local warning and remote warning parts of the strategy. The local warning aims to immediately inform the people inside the vehicle through various sensory stimuli, increasing alertness and survival chances; while the remote warning ensures that the emergency contacts outside the vehicle and professional rescue agencies can obtain key information and promptly initiate rescue actions. The synergy of these two strategies builds a comprehensive warning system that takes into account both internal and external factors, greatly enhancing the effectiveness and efficiency of emergency handling.

[0075] In this step, the secondary control strategy takes into account the complexity of the in-vehicle environment and the uncertainty of personnel responses, improving the timeliness and effectiveness of emergency responses through multi-level, multi-channel information transmission and warning mechanisms. It is an important component of the intelligent vehicle emergency handling system that bridges the gap between the previous step and the subsequent higher-level emergency measures, providing a solid foundation for subsequent higher-level emergency measures.

[0076] As an optional implementation, step S103, according to the three-level control strategy, controls the vehicle to drive to the target emergency site, including: according to the three-level control strategy, triggering the vehicle to start the automatic auxiliary navigation driving function, and navigating the vehicle to the target emergency site, wherein the target emergency site is the emergency site closest to the vehicle.

[0077] In this embodiment, when the vehicle's emergency handling system upgrades to the three-level control strategy, it means that the concentration of the preset type of gas (such as CO) in the vehicle has continuously exceeded the safety threshold, and the passengers inside the vehicle are in a non-responsive state. In this emergency situation, more proactive measures will be taken, namely starting the automatic auxiliary driving navigation function (NOA), to ensure that the passengers can be quickly sent to the nearest emergency site for timely medical treatment.

[0078] For example, assuming the preset gas is CO, after detecting abnormal CO concentration and personnel non-response, the NOA function will be automatically activated. NOA is an advanced automatic driving assistance technology that can autonomously control the vehicle's driving under certain conditions (such as urban roads and highways) without the need for passengers to manually operate the steering wheel or pedals. Using the vehicle's GPS positioning technology, the current location is quickly determined, and the nearest emergency site such as a hospital emergency room or emergency center is searched. This search process takes into account the real-time reception capacity of medical institutions and the feasibility of vehicle access, ensuring that the selected target can effectively respond to emergency situations.

[0079] Optionally, after the NOA function is activated, a shortest path from the current location to the target emergency treatment site can be automatically planned based on the current traffic conditions and road information. The path planning not only considers the distance, but also prioritizes routes with less traffic congestion and good road conditions to speed up the delivery. After the planning is completed, the vehicle will autonomously drive according to the preset route until it reaches the destination emergency treatment site.

[0080] Through the above steps, the three-level control strategy aims to use the vehicle's own automated driving capabilities to quickly and safely transport passengers in critical condition to professional medical treatment sites, minimizing health risks and potential casualties caused by poisoning of the preset type of gas. This series of operations reflects the autonomous response capabilities of intelligent vehicles in emergency situations and the high regard for the safety of passengers' lives.

[0081] As an optional implementation, during the process of navigating the vehicle to the target emergency treatment site, the method further includes: controlling the vehicle to send a pass request to the traffic signal control system closest to the vehicle, wherein the pass request is used to request the traffic signal control system to adjust the signal state of the signal light on the vehicle's driving route to a signal state that allows the vehicle to pass; and controlling the vehicle to play a request for avoidance to the outside world, wherein the request for avoidance is used to request traffic objects within a target range of the vehicle to avoid the vehicle.

[0082] In this embodiment, during the process of navigating the vehicle to the target emergency treatment site according to the three-level control strategy, in order to minimize traffic delays and ensure that the vehicle can quickly pass through the intersection, the system will automatically send a pass request to the traffic signal control system closest to the vehicle, requesting green light priority.

[0083] Optionally, the above communication request can be sent through the T-Box or V2X module on board, and the above communication request can include: real-time location, driving direction, speed of the vehicle, and emergency degree of the emergency treatment demand, etc. After receiving the request, the traffic signal control system will analyze the vehicle information and the current traffic conditions, and if the conditions allow, it will optimize the control logic of the traffic signal, generate a continuous green light pass wave for the emergency vehicle, reduce the waiting time at the signal light, and speed up the process of sending to the hospital. The control system of the vehicle will also consider safety factors when sending the pass request, such as ensuring that it will not pose a danger to other traffic participants, and only in safe and feasible conditions, the traffic signal priority function will be activated to avoid causing traffic chaos or accidents.

[0084] In this step, through the integration of the above-mentioned V2X communication function, the intelligent vehicle can interact efficiently and safely with the traffic infrastructure and other vehicles in the automatic driving emergency mode, which can save valuable time for the life safety of the passengers. The application of this technology not only embodies the automatic processing capability of intelligent vehicles in emergency situations, but also promotes the intelligentization and collaboration of the overall traffic system, which is an important direction for the development of intelligent traffic and intelligent vehicle safety technology in the future.

[0085] As an optional implementation, during the process of navigating the vehicle to the target emergency site, the method further comprises: controlling the vehicle to send emergency information to the target emergency site through the emergency cloud platform, wherein the emergency information at least includes the identification information of the vehicle and the health record information of the passengers inside the vehicle.

[0086] In this embodiment, when the three-level control strategy, i.e., the automatic driving emergency mode, is executed, in order to ensure that the rescue process after arrival can be started quickly, the strategy also contains a key pre-operation. For example, sending emergency information to the target emergency site through the emergency cloud platform. This measure aims to realize efficient information docking between the vehicle and the medical institution, and create favorable conditions for the emergency treatment to be accepted.

[0087] Optionally, the identification information of the vehicle usually refers to the VIN code of the vehicle, which is used to identify the vehicle. Through the VIN code, the target emergency site can quickly identify the vehicle model, manufacturer information, etc., which is crucial for understanding the internal structure and safety system configuration of the vehicle, and helps the rescue personnel to prepare the corresponding tools and equipment in advance.

[0088] Optionally, the health record information of the passengers includes important information such as the basic health status, past disease history, and drug allergy history of the passengers inside the vehicle. These information is extremely important for doctors to develop treatment plans in emergency situations, especially when the passengers cannot clearly express their own conditions. Health records can help doctors quickly judge the condition and take the most appropriate emergency measures.

[0089] Optionally, using the emergency cloud platform, the emergency handling system of the vehicle establishes a connection with the emergency cloud platform through the vehicle-mounted T-Bo. The emergency cloud platform is a comprehensive cloud service system that integrates medical resource scheduling and patient information management functions, and can quickly process and forward information needs in emergency situations. When the control system of the vehicle determines that the three-level control strategy must be started, the information sending mechanism can be automatically triggered. Without manual operation by the passengers, the emergency information will be uploaded to the emergency cloud platform in real time through the wireless network (such as 4G / 5G), and then forwarded to the medical information system of the target emergency site by the emergency cloud platform.

[0090] Optionally, after receiving the emergency information from the emergency cloud platform, the target emergency site will quickly allocate the required medical resources and professional doctors according to the vehicle identification information and the health records of the passengers, in preparation for the arrival of the vehicle. At the same time, the target emergency site can also use the location information provided by the vehicle to estimate the arrival time and reasonably arrange the rescue process and the preparation work of the emergency room.

[0091] Optionally, during the entire automatic driving to the hospital process, the vehicle will also continuously update the location information and real-time health monitoring data of the passengers in the vehicle. These updated information will also be transmitted to the target emergency site in real time through the emergency cloud platform, so as to dynamically adjust the rescue plan and ensure the timeliness and pertinence of the rescue.

[0092] In this step, the remote medical resource scheduling under the three-level control strategy realizes the information cooperation between the vehicle and the emergency site, not only speeding up the rescue response speed, but also improving the accuracy of the rescue, providing a strong guarantee for the life safety of the passengers in the vehicle in emergency situations.

[0093] As an optional implementation, after navigating the vehicle to the target emergency site, the method further includes: controlling the vehicle to play a help-seeking information to the outside world and controlling the vehicle to display a help-seeking signal, wherein the help-seeking information is used to remind the working objects in the target emergency site that the driving object on the vehicle has a rescue demand, and the help-seeking signal is used to transmit visual prompt information of the rescue demand to the outside world.

[0094] In this embodiment, after the vehicle is automatically driven to the target emergency site, in order to ensure that the rescue personnel can quickly locate the vehicle and understand the emergency situation of the passengers in the vehicle, the vehicle can be further controlled to play help-seeking information to the outside world and display a help-seeking signal. These operations are crucial for improving the rescue efficiency and saving time for treatment.

[0095] Optionally, the vehicle can be controlled to play help-seeking information to the outside world, for example, the control system of the vehicle activates the directional speaker outside the vehicle to continuously play the preset emergency help-seeking information. This information usually includes the specific rescue demand of the vehicle, such as "the passengers in the vehicle need emergency medical assistance", as well as a brief situation explanation (such as CO poisoning) and any specific rescue guidance (such as requesting professional personnel to act quickly). The playing of the help-seeking information can guide the staff in the emergency site to quickly pay attention to the emergency state, even in a noisy environment, to ensure that the information is effectively conveyed. This helps the rescue team to respond quickly and improves the timeliness of the rescue.

[0096] Optionally, the vehicle display can be controlled to display a distress signal, for example, the interior and exterior light system of the vehicle will be controlled to display a special distress signal, which includes: the double flashing warning light of the vehicle will be started in a high frequency flashing manner, which is the standard signal of emergency vehicle passing, which can attract the attention of the surrounding people. And the Light Emitting Diode (LED) display screen equipped in the license plate area of the vehicle displays the "SOS" distress signal, which is an internationally recognized distress signal that can immediately convey the information that the vehicle is in an emergency state.

[0097] Optionally, through the display of visual distress signals, a more intuitive rescue prompt is provided to the outside world, ensuring that the rescue signal can still be quickly identified even in an environment where hearing may be limited, such as the noise inside an emergency site or the wearing of hearing protection equipment by workers.

[0098] Optionally, the playing of the distress information and the display of the distress signal together constitute an important means for the intelligent vehicle to communicate with the outside world in an emergency after reaching the target emergency site. These operations not only improve the alertness of rescue personnel, but also ensure the rapid deployment of rescue operations, and save valuable treatment time for the vehicle occupants. In a critical moment, every second saved can be life and death, so efficient execution of this link is of great significance to reducing the risk of injury and death.

[0099] Optionally, through the above design, not only measures are taken inside the vehicle to deal with emergency situations such as carbon monoxide poisoning, but also a seamless connection mechanism from in-vehicle emergency treatment to external rapid rescue is established through effective communication between the vehicle and the outside world, realizing true "self-rescue + other rescue" cooperation and providing all-round protection for the life safety of the driver and passengers.

[0100] The above technical solutions of the embodiments of the present application will be further introduced by examples in combination with the preferred embodiments of the present application.

[0101] In the field of intelligent vehicles, with the development of electrification and intelligence of vehicles, the safety of the vehicle environment has become a key issue that cannot be ignored. Especially in the case of CO poisoning, since CO is colorless and odorless, it is not easy to detect, and it is easy to accumulate in a closed environment, thus posing a significant threat to drivers and passengers. The emergency handling of CO poisoning usually relies on simple ventilation strategies, including automatic window opening and engine shutdown. However, this method is greatly reduced in effectiveness or even completely ineffective in extreme environments (such as heavy rain, vehicle wading) or when the vehicle is completely closed. In addition, relying solely on ventilation cannot quickly reduce high concentrations of CO, especially when the engine continues to produce CO, further increasing the risk to the occupants. Moreover, the traditional emergency plan for carbon monoxide poisoning usually relies on the initiative of the driver and passengers to seek help. However, in the case of CO poisoning, the driver and passengers will soon lose consciousness and be unable to communicate effectively for help, greatly increasing the likelihood of rescue delays and posing a serious threat to life safety.

[0102] In view of the above technical problems, the present application provides a control method for a vehicle, applied to a control system of the vehicle, aiming to build a comprehensive, efficient and intelligent safety protection system by comprehensively using physical removal, multi-modal early warning, automatic driving first aid and in-vehicle and out-of-vehicle collaborative rescue means. When detecting abnormal CO concentration in the vehicle, the ventilation strategy or gas replacement strategy can be intelligently selected according to the environmental conditions to reduce the concentration of harmful gases; and through the in-vehicle early warning and remote linkage mechanism, the driver and passengers in the vehicle and the emergency contact person associated with the vehicle are immediately notified, and even an emergency call is automatically dialed, uploading the vehicle location and personnel health information. In more serious poisoning situations, the automatic driving function will be activated to navigate the vehicle to the nearest emergency location and communicate with traffic lights through V2X technology to request priority passage; at the same time, the out-of-vehicle loudspeaker is used to issue avoidance instructions to ensure safe and rapid arrival. In addition, external medical resources can also be actively dispatched, including medical resource reservation before arrival and out-of-vehicle warning and personnel evacuation after arrival, truly realizing seamless connection from self-rescue to rescue by others, not only overcoming the limitations of related technologies in extreme environments, but also forming a closed emergency chain by integrating advanced vehicle control technologies and external rescue resources, significantly improving the response speed and processing efficiency of the vehicle in the face of emergency events such as carbon monoxide poisoning, and providing a more solid guarantee for the safety of drivers and passengers.

[0103] Next, the vehicle control system in the implementation of the present application will be introduced.

[0104] Figure 2 is a schematic diagram of a vehicle control system according to an embodiment of the present application, which includes a multi-level emergency handling module for CO poisoning. As shown in Figure 2As shown, the control system of the vehicle mainly includes: an environment perception layer 201, a vehicle control layer 202, and a communication rescue layer 203.

[0105] Optionally, the environment perception layer 201 is used to collect the environmental data inside and outside the vehicle for subsequent decision-making and emergency response, wherein the environment perception layer 201 includes a multi-zone high-precision CO sensor 2011 and an environmental sensor 2012, wherein the multi-zone high-precision CO sensor 2011 is respectively arranged in the driver's cabin 20111, the rear row 20112 and the air conditioning air duct 20113 of the vehicle, etc. to accurately detect the CO concentration in different areas inside the vehicle, ensuring the comprehensiveness of coverage and the accuracy of detection. The environmental sensor 2012 is used to provide environmental information of the current environment in which the vehicle is located, wherein the environmental sensor 2012 can include a GPS positioning sensor 20121, a rainfall detection sensor 20122, and a vehicle wading sensor 20123, etc. Through the multiple sensors, not only the concentration of CO inside the vehicle can be detected, but also necessary environmental information such as the vehicle position, the weather condition of the current environment in which the vehicle is located, and the wading condition of the vehicle can be provided to assist in decision-making of emergency handling strategies.

[0106] Optionally, the vehicle control layer 202 is used to perform corresponding control operations according to the data transmitted by the environment perception layer 201 to cope with CO poisoning events. Wherein the vehicle control layer 202 mainly includes a CO removal unit 2021 and a vehicle control unit 2022, wherein the CO removal unit 2021 includes various execution control mechanisms, such as a lifting window / skylight 20211, which reduces the CO concentration inside the vehicle through ventilation; a vehicle-mounted nitrogen storage tank 20212 with an electronic valve control, which is used to release inert gas to dilute the CO concentration inside the vehicle in a closed or harsh environment; an oxygen supply regeneration module 20213, which is used to produce oxygen by electrolyzing water and deliver the oxygen to the inside of the vehicle to directly increase the oxygen concentration inside the vehicle.

[0107] Optionally, the vehicle control unit 2022 includes an engine control module 20221, an NOA automatic driving unit 20222, and an outdoor directional loudspeaker 20223. Wherein the engine control module 20221 is used to control the engine start-stop, the NOA automatic driving unit 20222 is used to control the automatic driving of the vehicle, and the outdoor directional loudspeaker 20223 is used to send warning prompt information outside.

[0108] Optionally, the communication rescue layer 203 includes a vehicle-mounted T-Box unit 2031, wherein the vehicle-mounted T-Box unit can send emergency messages to an emergency linkage cloud platform 2032, an emergency center 2033, and a medical resource scheduling interface 2034 through 4G / 5G communication.

[0109] In the control system of the vehicle, a multi-level and intelligent emergency treatment system is included from perception, control to communication. The vehicle interior environment is continuously monitored by the environment perception layer. Once the carbon monoxide concentration is found to be abnormal, the vehicle control layer immediately performs CO removal and vehicle control response, and the communication rescue layer starts emergency communication with the outside to ensure that the rescue force is notified and dispatched in the first time, forming a full range of emergency response chain of in-vehicle treatment, automatic driving to hospital, medical resource pre-scheduling and outside gathering.

[0110] Next, the processing flow of the multi-level emergency treatment of physical removal, multi-modal early warning, automatic driving first aid and in-vehicle and out-of-vehicle cooperative rescue in the embodiment of the application is further introduced.

[0111] Figure 3 is a flowchart of a vehicle multi-level control method according to an embodiment of the application. As shown in Figure 3 , a multi-level control method when the vehicle detects that the gas concentration exceeds the standard is introduced taking CO as an example, wherein the method mainly includes a complete set of emergency treatment logic from detecting CO concentration abnormality to finally executing external medical resource gathering, as shown in Figure 3 , the method mainly includes the following steps.

[0112] Step S301, detecting the CO concentration in the vehicle.

[0113] In this embodiment, when the high-precision CO sensor in the vehicle detects that the gas concentration reaches or exceeds the preset threshold, the system immediately starts the emergency response process.

[0114] Step S302, removing the CO concentration.

[0115] In this embodiment, when the CO concentration in the vehicle is detected to be abnormal, the CO concentration in the vehicle is reduced by a ventilation strategy or a gas replacement strategy.

[0116] Step S303, multi-modal early warning and remote linkage.

[0117] In this embodiment, in addition to performing step S302 to reduce the CO concentration in the vehicle when the CO concentration in the vehicle is detected to be abnormal, the vehicle occupants can also be awakened by multi-modal early warning, and the emergency contact objects associated with the vehicle can be reminded by remote linkage, and in necessary cases, the rescue information can be sent to the emergency site.

[0118] Step S304, judging whether the CO concentration in the vehicle is ≥ the preset concentration threshold and whether the vehicle occupants are in a non-response state.

[0119] In this embodiment, if after the above steps are performed, it can be further determined whether the CO concentration inside the vehicle is greater than or equal to a preset concentration threshold, and whether the driver and passenger inside the vehicle are in an unresponsive state. If the CO concentration inside the vehicle is greater than or equal to the preset concentration threshold (e.g., 100 ppm) for a preset time period, and the driver and passenger inside the vehicle are unresponsive, in this case, step S305 will be performed, if the CO concentration inside the vehicle is less than the preset concentration threshold, and the driver and passenger inside the vehicle are responsive, in this case, step S306 will be performed.

[0120] Step S305, start the driving first aid mode.

[0121] In this embodiment, in the case that the CO concentration inside the vehicle is greater than or equal to the preset concentration threshold for a preset time period, and the driver and passenger inside the vehicle are unresponsive, the NOA automatic driving module will be activated to automatically navigate the vehicle to the nearest first aid center. During the navigation to the first aid center, the vehicle can communicate with the traffic light system through V2X technology to request priority right of way to reduce traffic delay. At the same time, the external loudspeaker continuously broadcasts information requesting other vehicles to avoid, to ensure the smoothness of the medical process.

[0122] Step S306, end.

[0123] In this embodiment, if the CO concentration inside the vehicle is less than the preset concentration threshold, and the driver and passenger inside the vehicle are responsive, it means that the CO concentration inside the vehicle has returned to normal, and the driver and passenger inside the vehicle are in a safe state, in this case, the entire process will be directly ended.

[0124] Step S307, call for medical resources outside the vehicle.

[0125] In this embodiment, before the vehicle arrives at the first aid site, the first aid site can be reserved in advance for treatment. After the vehicle arrives at the first aid site, the staff in the first aid site can be reminded through the help information and help signal that there is an emergency rescue demand for the driver and passenger inside the vehicle. After the driver and passenger inside the vehicle are rescued, step S306 will be performed to end the entire process.

[0126] In the above steps, starting from the gas concentration detection, the activation conditions and execution actions of each emergency level are gradually shown. The logical judgment and emergency operation of each level are closely connected to form a closed-loop emergency handling mechanism, which ensures that appropriate measures can be taken in any case to protect the safety of the driver and passenger.

[0127] Optionally, the above step S302 can be implemented by the CO concentration removal method shown in the following table, Figure 4 Figure 4 ​is a flowchart of a CO concentration removal method according to an embodiment of the present application, as shown in Figure 4 The method comprises the following steps.

[0128] In step S3021, environment information of the environment in which the vehicle is currently located is acquired.

[0129] In this embodiment, in response to the abnormality of the CO concentration in the vehicle interior, the environment information of the environment in which the vehicle is currently located is acquired, wherein the environment information is used to determine whether the environment in which the vehicle is currently located is an extreme environment (such as heavy rain, wading, etc.).

[0130] In step S3022, it is determined whether the environment in which the vehicle is currently located is an extreme environment based on the environment information.

[0131] In this embodiment, if the environment information acquired according to the above step S3021 determines that the environment in which the vehicle is currently located is not an extreme environment, step S3023 is performed. If the environment information acquired according to the above step S3021 determines that the environment in which the vehicle is currently located is an extreme environment, step S3024 is performed.

[0132] In step S3023, the vehicle window / sunroof is opened.

[0133] In this embodiment, if the environment in which the vehicle is currently located is not an extreme environment, the CO concentration in the vehicle interior is reduced by opening the vehicle window or sunroof to increase ventilation.

[0134] In step S3024, nitrogen purging and oxygen supply regeneration are started.

[0135] In this embodiment, if the environment in which the vehicle is currently located is an extreme environment, the gas is diluted by starting the on-board nitrogen purging, and the oxygen supply regeneration module is activated to supply fresh oxygen by using the electrolytic water oxygen production technology, so as to ensure that CO can be effectively removed even in a sealed or harsh condition.

[0136] In the above steps S3021 to S3024, when the abnormality of the CO concentration in the vehicle interior is detected, the environment information of the environment in which the vehicle is located is first acquired and analyzed, and then it is determined whether the vehicle is in an extreme environment according to the environment information of the environment in which the vehicle is located. For a non-extreme environment, a conventional ventilation strategy of opening the vehicle window / sunroof is adopted to rapidly reduce the CO concentration in the vehicle interior and protect the health of the passengers. In the face of an extreme environment, nitrogen purging and oxygen supply regeneration are started to dilute the toxic gas by releasing the inert gas (nitrogen) on board, and to create a safe breathing environment in the vehicle by using the electrolytic water oxygen production technology. This differentiated processing strategy not only improves the flexibility and efficiency of CO poisoning emergency treatment, but also ensures effective rescue under various environmental conditions, significantly enhancing the safety performance of the vehicle and providing all-round protection for the life safety of the passengers.

[0137] Optionally, when the pre-warning information is generated by the multi-modal pre-warning and remote linkage mode, the step S303 can be implemented by Figure 5 as shown in the multi-modal pre-warning and remote linkage method, Figure 5 is a flow chart of a multi-modal pre-warning and remote linkage method according to an embodiment of the present application, as shown in the method comprises the following steps: Figure 5

[0138] Step S3031, multi-modal pre-warning in the vehicle.

[0139] In this embodiment, the driver and passengers in the vehicle can be reminded by multi-modal methods such as seat vibration, voice broadcast, and instrument pop-up red pop-up window.

[0140] Step S3032, remote pre-warning.

[0141] In this embodiment, pre-warning information can be sent to the mobile terminal of the emergency contact person associated with the vehicle, wherein the pre-warning information at least includes the position of the vehicle and the CO concentration change. In addition, the customer service center E-call can be automatically triggered, and the vehicle VIN code and the owner health profile information can be uploaded.

[0142] Step S3033, control T-Box to automatically call emergency phone.

[0143] In this embodiment, the T-Box on the vehicle automatically dials the emergency center phone and sends a help information, wherein the help information can be: "CO concentration in vehicle with license plate XXX exceeds the standard, coordinates XXX, request for rescue", which is only an example.

[0144] In the above steps S3031 to S3033, through multi-level pre-warning strategy, through the combination of in-vehicle immediate warning and remote precise rescue, an efficient and comprehensive emergency response network is constructed, which significantly improves the survival probability in CO poisoning emergency and provides strong guarantee for passenger safety.

[0145] The above step S307 can be implemented by Figure 6 as shown in the vehicle medical resource calling method. As shown in Figure 6 the method comprises the following steps.

[0146] Step S3071, make an appointment for emergency department to prepare for treatment through the emergency cloud platform.

[0147] In this embodiment, before the vehicle arrives at the emergency site, the emergency department can be prepared for treatment in advance through the emergency cloud platform.

[0148] Step S3072, the vehicle plays the help information and displays the help signal. ​

[0149] In this embodiment, the vehicle's external loudspeaker starts playing a distress signal to inform the surrounding crowd that the vehicle's occupants are in danger and need immediate medical assistance. At the same time, the vehicle displays a distress signal to attract attention. For example, the vehicle's double flasher starts high-frequency flashing, and the license plate LED display screen displays an "SOS" signal to ensure that medical personnel respond promptly and carry out rescue work.
