[0022] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0023] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs.

[0024] Based on the description of the background technology, off-road self-driving travel has become a popular choice for more and more outdoor enthusiasts, especially in challenging journeys in remote areas and extreme environments. However, in such an environment, severe weather conditions and terrain complexity can pose a serious threat to the physical health of off-road enthusiasts, especially the problem of rapid drop in body temperature (hypothermia). When the core body temperature of the human body drops below 35°C, hypothermia symptoms will appear, which may further lead to life-threatening situations. Current vehicle safety systems are mostly designed to monitor external factors such as driving environment and vehicle conditions, but there is a lack of intelligent detection and emergency response solutions for passenger health status, especially for the problem of human hypothermia. There is no perfect solution.

[0025] As mentioned above, how to handle emergencies for drivers and passengers in abnormal conditions has become an important research issue.

[0026] Based on the above description, if Figure 1 As shown, the vehicle control method proposed in this embodiment includes:

[0027] Step 101, obtaining characteristic data of the driver and passengers.

[0028] In a specific implementation, the characteristic data of the driver and passenger is data that can reflect the biological characteristics of the driver and passenger. The characteristic data of the driver and passenger is collected by using sensors.

[0029] The characteristic data includes: body temperature data, heart rate data and respiration data. The sensors include: infrared body temperature sensor, heart rate sensor and respiration sensor. The infrared body temperature sensor is used to obtain the body temperature data of the driver and passengers; the heart rate sensor is used to obtain the heart rate data of the driver and passengers; and the respiration sensor is used to obtain the respiration data of the driver and passengers.

[0030] The body temperature sensor can be a non-contact infrared body temperature sensor, which monitors the body temperature data of the driver and passengers in real time by detecting the infrared radiation emitted by the driver and passengers' bodies. The infrared body temperature sensor is not blocked by clothing, can quickly obtain the body temperature data of the driver and passengers, and is flexible to install without causing discomfort to the driver and passengers. The infrared body temperature sensor can be installed in the seat back area, the top of the cabin or the inside of the door to ensure that the infrared body temperature sensor can cover the upper body of the driver and passengers.

[0031] Heart rate sensors and respiration sensors can be patch-type or seat-integrated sensors. Heart rate sensors can be built into seat armrests or seat surfaces to measure heart rate data in real time when in contact with the body of the driver or passenger. Respiration sensors can be embedded in seat backs or seat cushions to assess respiration data by detecting chest or abdominal movements of the driver or passenger.

[0032] Step 102, in response to determining that the characteristic data is less than a preset normal state characteristic threshold, determining that the driver and passenger is in an abnormal state.

[0033] In specific implementation, the characteristic data includes: body temperature data, heart rate data and breathing data. The abnormal state refers to the hypothermia state. The hypothermia state refers to the state in which the body's heat loss is greater than the heat supply, resulting in a decrease in the temperature of the body's core area.

[0034] When the body temperature data is less than the preset normal body temperature threshold, it is determined that the driver and passenger are in an abnormal state. Or, when the heart rate data is less than the preset normal heart rate threshold, it is determined that the driver and passenger are in an abnormal state. Or, when the breathing data is less than the preset normal breathing threshold, it is determined that the driver and passenger are in an abnormal state.

[0035] Step 103, heating the position where the driver and passenger are in the abnormal state.

[0036] In specific implementation, after determining that the driver and passenger are in an abnormal state, the abnormal protection mode is turned on. Heating the driver and passenger in the abnormal state can provide heat for the driver and passenger in the abnormal state and help the driver and passenger in the abnormal state to return to a normal state.

[0037] By forming a closed space at the location of the driver and passenger in an abnormal state and heating the closed space, it is possible to provide heat to the driver and passenger while minimizing the heat loss of the driver and passenger, quickly helping the driver and passenger in an abnormal state to restore normal body temperature, and realizing emergency treatment for the driver and passenger in an abnormal state, thus avoiding the life-threatening situation of the driver and passenger due to being in an abnormal state for a long time.

[0038] Through the above-mentioned embodiments, characteristic data of the driver and passenger are obtained. When the characteristic data is less than the preset characteristic threshold of the normal state, it is determined that the driver and passenger are in an abnormal state. The position where the driver and passenger are in the abnormal state is heated. In this way, when the characteristic data of the driver and passenger is less than the preset characteristic threshold of the normal state, it is possible to accurately detect that the driver and passenger are in an abnormal state. By heating the position where the driver and passenger are in an abnormal state, the driver and passenger in the abnormal state can be helped to return to the normal state in time, and emergency treatment can be performed on the driver and passenger in the abnormal state to avoid life-threatening situations due to being in the abnormal state for a long time.

[0039] Since the position of the driver and passenger in the abnormal state is uncertain, a closed space is formed for the position of the driver and passenger in the abnormal state, and the heating system in the closed space is used to provide heat to the driver and passenger in the abnormal state. The specific process is as follows:

[0040] In some embodiments, step 103 includes:

[0041] Step 1031, determining the location of the driver and passenger in the abnormal state.

[0042] Step 1032, forming the space corresponding to the position into a closed space, and heating the closed space.

[0043] In a specific implementation, the position of the driver and passenger in an abnormal state is determined. When the position of the additional person in an abnormal state is the trunk position, the space corresponding to the trunk position is formed into a closed trunk space, and the closed trunk space is heated. When the position of the driver and passenger in an abnormal state is the cockpit position, the space corresponding to the cockpit position is formed into a closed cockpit space, and the closed cockpit space is heated.

[0044] Through the above scheme, when the driver and passenger are in an abnormal state, the space corresponding to the position of the driver and passenger in the abnormal state is formed into a closed space, and the closed space is heated. In this way, by forming a closed space, heat can be provided to the driver and passenger in the abnormal state as soon as possible when the closed space is heated, and the heat loss of the driver and passenger in the abnormal state is avoided to the greatest extent, so that the driver and passenger in the abnormal state can quickly return to temperature.

[0045] When the driver or passenger in an abnormal state is located in the trunk of the vehicle, the enclosed space of the trunk is heated. The specific process is as follows:

[0046] In some embodiments, step 1032 includes:

[0047] Step 1032A, in response to determining that the position is the position of the vehicle trunk, controlling the heat insulation plate between the vehicle trunk and the rear seats to extend to form a closed trunk space.

[0048] Step 1032B, using the heating system disposed at the bottom of the vehicle trunk and / or the air conditioning system disposed in the vehicle trunk, the enclosed space of the trunk is heated.

[0049] In specific implementation, since the trunk space of the vehicle is small and well-sealed, it is convenient for the driver and passengers in abnormal state to quickly warm up. Therefore, it is preferred to warm up the driver and passengers in abnormal state in the trunk space.

[0050] When the driver and passenger are in an abnormal state, the position of the driver and passenger is determined. When the position of the driver and passenger in the abnormal state is the cockpit position, the driver and passenger in the abnormal state is prompted to move to the trunk position. When the position of the driver and passenger in the abnormal state is the trunk position, the space corresponding to the trunk position is formed into a closed trunk space, and the closed trunk space is heated.

[0051] Specifically, a retractable heat insulation board (heat insulation board) is provided between the vehicle trunk and the cabin, a heating system (e.g., electric heating board or embedded heating module) is provided at the bottom of the vehicle trunk, and an air conditioning vent is provided inside the vehicle trunk. When the position of the driver and passenger in an abnormal state is the trunk position, the heat insulation board is controlled to extend to form a closed space in the trunk, and the closed space in the trunk is heated by the heating system and / or the air conditioning system. In order to help the driver and passenger in an abnormal state to quickly recover, it is preferred to heat the closed space in the trunk by the heating system and the air conditioning system.

[0052] Through the above scheme, when the position of the driver and passengers in an abnormal state is the trunk, the heat insulation plate is controlled to extend to form a closed space in the trunk, and the heating system and the air-conditioning system are used to heat the closed space in the trunk, so as to facilitate the rapid warming up of the driver and passengers in the abnormal state.

[0053] When the driver and passenger in an abnormal state are located in the vehicle cabin, the enclosed space of the cabin is heated. The specific process is as follows:

[0054] In some embodiments, step 1032 includes:

[0055] Step 1032a, in response to determining that the position is a vehicle cabin position, controlling a heat insulation plate between the vehicle cabin and the trunk to extend to form a closed cabin space.

[0056] Step 1032b, utilizing the air conditioning system provided in the vehicle cabin to heat the enclosed space of the cabin.

[0057] In specific implementation, the vehicle cabin space can also be formed into a closed space, and the temperature of the driver and passenger in an abnormal state can also be restored. Therefore, when the driver and passenger in an abnormal state is located in the cabin and cannot move to the trunk, the driver and passenger in an abnormal state is restored in the cabin space.

[0058] When the driver and passenger are in an abnormal state, the position of the driver and passenger is determined. When the position of the driver and passenger in the abnormal state is the cockpit position, the driver and passenger in the abnormal state is prompted to move to the trunk position. When the driver and passenger in the abnormal state does not move to the trunk position within a preset time, the space corresponding to the cockpit position is formed into a cockpit enclosed space, and the cockpit enclosed space is heated.

[0059] Specifically, a retractable heat insulation board (heat insulation board) is provided between the vehicle cabin and the trunk, and an air conditioning vent is provided inside the vehicle cabin. When the driver and passenger in an abnormal state are in the cabin and cannot move to the trunk within a preset time, the heat insulation board is controlled to extend to form a closed cabin space, and the closed cabin space is heated by the air conditioning system.

[0060] Through the above scheme, when the position of the driver and passenger in the abnormal state is in the cockpit, the heat insulation board is controlled to extend to form an enclosed space in the cockpit, and the air-conditioning system is used to heat the enclosed space in the cockpit, so as to facilitate the rapid warming up of the driver and passenger in the abnormal state.

[0061] After determining that the driver and passenger are in an abnormal state, the severity of the abnormal state of the driver and passenger is determined. According to the severity of the abnormal state of the driver and passenger, the vehicle is controlled to rescue the driver and passenger in the abnormal state in a corresponding manner. The specific process is as follows:

[0062] In some embodiments, step 102 includes:

[0063] Step 102A: Process the feature data to obtain target features.

[0064] Step 102B, in response to determining that the target feature is less than a preset first feature threshold and greater than or equal to a preset second feature threshold, determining that the driver and passenger are in a first abnormal state.

[0065] Step 102C, in response to determining that the target feature is less than a preset second feature threshold, determining that the driver and passenger are in a second abnormal state.

[0066] In the specific implementation, the feature data is preprocessed to obtain the target feature. The feature data is data related to the biometrics of the driver and passengers collected by the sensor, and the target feature is the feature after the feature data is preprocessed. The preprocessing includes: data cleaning processing and data synchronization processing.

[0067] When the target feature is less than a preset first feature threshold and greater than or equal to a preset second feature threshold, it is determined that the driver and passenger are in a first abnormal state. The first feature threshold is greater than the second feature threshold. The first abnormal state refers to a general abnormal state.

[0068] For example, the target feature is a target temperature, the preset first temperature threshold is 35° C., and the preset second temperature threshold is 33° C. When the target temperature is 34° C., it is determined that the driver and passenger are in a first abnormal state.

[0069] When the target feature is less than a preset second feature threshold, it is determined that the driver and passenger are in a second abnormal state, wherein the second abnormal state refers to a severe abnormal state.

[0070] For example, the target feature is a target temperature, the preset first temperature threshold is 35° C., and the preset second temperature threshold is 33° C. When the target temperature is 32° C., it is determined that the driver and passenger are in the second abnormal state.

[0071] After step 103, the method further includes:

[0072] Step 103A, in response to determining that the abnormal state is the first abnormal state, sending a rescue prompt message.

[0073] Step 103B, in response to determining that the abnormal state is the second abnormal state, sending a rescue prompt message, and controlling the vehicle to travel to the target location.

[0074] In specific implementation, when the driver and passenger are in the first abnormal state (general abnormal state), in addition to heating the position of the driver and passenger, a rescue prompt message is also sent. In this way, in addition to helping the driver and passenger in the first abnormal state to warm up, the rescue prompt message can also be sent to seek help from the outside.

[0075] When the driver and occupants are in the second abnormal state (severe abnormal state), in addition to heating the location of the driver and occupants, rescue prompt information is sent and the vehicle is controlled to drive to the target location. In this way, in addition to helping the driver and occupants in the second abnormal state to warm up, rescue prompt information can be sent to seek external help and the driver and occupants in the second abnormal state can be transported to the target location for treatment to avoid life-threatening situations for the driver and occupants in the second abnormal state.

[0076] Through the above scheme, by processing the characteristic data, the target characteristics obtained are made more accurate. When the target characteristic is less than the preset first characteristic threshold and greater than or equal to the preset second characteristic threshold, it is possible to accurately determine that the driver and passenger are in the first abnormal state, and seek outside help by sending a rescue prompt message, so that outsiders can rescue the driver and passenger in the first abnormal state. When the target characteristic is less than the preset second characteristic threshold, it is possible to accurately determine that the driver and passenger are in the second abnormal state. While sending the rescue prompt message, the vehicle is controlled to travel to the target location, and the driver and passenger in the second abnormal state can be transported to the target location for treatment, avoiding life-threatening situations for the driver and passenger in the second abnormal state.

[0077] When judging whether the driver or passenger is in an abnormal state based on the feature data, in order to make an accurate judgment, the feature data needs to be processed. The specific process of processing the feature data to obtain the target feature is as follows:

[0078] In some embodiments, the characteristic data includes body temperature data, heart rate data and breathing data; step 102A includes:

[0079] Step 102Aa, performing average processing on multiple body temperature data in the current time period to obtain the target body temperature.

[0080] Step 102Ab, time-synchronize the heart rate data and the target body temperature, and determine the target heart rate in the current time period from the heart rate data.

[0081] Step 102Ac, time-synchronize the breathing data and the target body temperature, and determine the target breathing in the current time period from the breathing data.

[0082] In specific implementation, the target body temperature is made more accurate by processing the body temperature data. Specifically, the current time period is determined, and the multiple body temperature data in the current time period are averaged to obtain the target body temperature. For example, the current time period is determined to be T0 to T1. If the body temperature data in the current time period T0 to T1 is 35°C, 34.8°C, and 34.6°C, the target body temperature is determined to be 34.8°C.

[0083] By synchronizing the heart rate data, breathing data and target body temperature, the problem of not being able to accurately judge whether the driver and passengers are in an abnormal state due to the asynchrony of the target heart rate, target breathing and target body temperature can be avoided. Specifically, the target heart rate in the current time period is determined from the heart rate data; the target breathing in the current time period is determined from the breathing data. For example, if the current time period corresponding to the target body temperature is T0 to T1, the target heart rate in the current time period T0 to T1 is determined from multiple heart rate data, and the target breathing in the current time period T0 to T1 is determined from multiple breathing data.

[0084] In addition, abnormal data is determined from the feature data, and the abnormal data in the feature data is cleaned to obtain the target feature. Specifically, abnormal body temperature is determined from the body temperature data, and the abnormal body temperature in the body temperature data is cleaned to obtain the target body temperature; abnormal heart rate is determined from the heart rate data, and the abnormal heart rate in the heart rate data is cleaned to obtain the target heart rate; abnormal breathing is determined from the breathing data, and the abnormal breathing in the breathing data is cleaned to obtain the target breathing.

[0085] Through the above scheme, the target body temperature is processed to make the target body temperature more accurate, avoiding the error caused by inaccurate body temperature data collected by the body temperature sensor. By synchronizing the heart rate data, breathing data and target body temperature, the problem of not being able to accurately judge whether the driver and passengers are in an abnormal state due to the asynchrony of the target heart rate, target breathing and target body temperature is avoided.

[0086] In some embodiments, the target characteristics include target body temperature, target heart rate, and target respiration; step 102B includes:

[0087] Step 102Ba, in response to determining that the target body temperature is less than a preset first body temperature threshold and greater than or equal to a preset second body temperature threshold, determines that the driver and passenger are in a first abnormal state.

[0088] Alternatively, step 102Bb, in response to determining that the target heart rate is less than a preset first heart rate threshold and greater than or equal to a preset second heart rate threshold, it is determined that the driver and passenger are in a first abnormal state.

[0089] Alternatively, in step 102Bc, in response to determining that the target breathing is less than a preset first breathing threshold and greater than or equal to a preset second breathing threshold, it is determined that the driver and passenger are in a first abnormal state.

[0090] In specific implementation, the normal body temperature range under normal human condition is 36.5℃-37℃, the normal heart rate range is 60 times / minute-100 times / minute, and the normal breathing range is 12 times / minute-20 times / minute. When the target feature is less than the corresponding normal range, it is determined that the driver and passenger are in the first abnormal state.

[0091] For example, the preset first body temperature threshold is 35°C, and the preset second body temperature threshold is 33°C. The preset first heart rate threshold is 60 times / minute, and the preset second heart rate threshold is 40 times / minute. The preset first breathing threshold is 12 times / minute, and the preset second breathing threshold is 10 times / minute. When the target body temperature is 34°C, it is determined that the driver and passenger are in the first abnormal state. Alternatively, when the target heart rate is 50 times / minute, it is determined that the driver and passenger are in the first abnormal state. Alternatively, when the target breathing is 11 times / minute, it is determined that the driver and passenger are in the first abnormal state.

[0092] In addition, in order to avoid the problem that the target body temperature alone cannot accurately determine whether the driver or passenger is in an abnormal state, the target body temperature, target heart rate and target respiration are used to determine whether the driver or passenger is in the first abnormal state. When the target body temperature is less than the preset first body temperature threshold and greater than or equal to the preset second body temperature threshold, the target heart rate is less than the preset first heart rate threshold and greater than or equal to the preset second heart rate threshold, and the target respiration is less than the preset first respiration threshold and greater than or equal to the preset second respiration threshold, it is determined that the driver or passenger is in the first abnormal state.

[0093] For example, the preset first temperature threshold is 35°C, and the preset second temperature threshold is 33°C. The preset first heart rate threshold is 60 times / minute, and the preset second heart rate threshold is 40 times / minute. The preset first breathing threshold is 12 times / minute, and the preset second breathing threshold is 10 times / minute. When the target body temperature is 34°C, the target heart rate is 50 times / minute, and the target breathing is 11 times / minute, it is determined that the driver and passenger are in the first abnormal state.

[0094] Through the above scheme, when the target body temperature is less than the preset first body temperature threshold and greater than or equal to the preset second body temperature threshold, it can be accurately determined that the driver and occupant are in the first abnormal state. When the target heart rate is less than the preset first heart rate threshold and greater than or equal to the preset second heart rate threshold, it can be accurately determined that the driver and occupant are in the first abnormal state. When the target respiration is less than the preset first respiration threshold and greater than or equal to the preset second respiration threshold, it can be accurately determined that the driver and occupant are in the first abnormal state. In addition, judging whether the driver and occupant is in the first abnormal state based on the target body temperature, target heart rate and target respiration can also avoid the problem of inaccurate judgment when judging only based on the target body temperature.

[0095] After determining that the driver and passengers are in an abnormal state, in addition to warming up the driver and passengers in the abnormal state, a rescue prompt needs to be sent to facilitate the rescue of the driver and passengers in the abnormal state. The specific process is as follows:

[0096] In some embodiments, step 103A or step 103B includes:

[0097] Step 103Aa, sending the rescue prompt information to the terminal device of the preset contact person through the vehicle system, and sending the rescue prompt information outside the vehicle by controlling the vehicle alarm system alarm.

[0098] In specific implementation, multiple ways of sending rescue prompt information are preset. The rescue prompt information is sent according to multiple preset ways. Alternatively, a target prompting way is determined from multiple preset ways, and the rescue prompting information is sent according to the target prompting way.

[0099] The preset contact person is the emergency contact person preset by the driver and passengers. When the driver and passengers are in an abnormal state, the vehicle system sends rescue prompt information to the terminal device of the preset contact person through satellite communication or mobile network communication, which is convenient for the preset contact person to rescue the driver and passengers in abnormal state. By controlling the vehicle alarm system to send rescue prompt information outside the vehicle, it is convenient for other people outside the vehicle to rescue the driver and passengers in abnormal state.

[0100] After step 103, it also includes: obtaining the current power of the vehicle; in response to determining that the current power is less than a preset power threshold, turning on the energy-saving mode, determining a target application function that is not related to the abnormal protection mode from the background application, and turning off the target application function.

[0101] When the vehicle's current battery level is less than the preset battery threshold, it means that the vehicle's current battery level is low. By shutting down target application functions in the background application that are not related to the abnormal protection mode, the vehicle's battery level is preferentially allocated to the heating module used to warm up the driver and passengers in an abnormal state, while ensuring that the vehicle's key functions (for example, the engine, electronic control system) are not affected.

[0102] Through the above scheme, the rescue prompt information is sent to the terminal device of the preset contact person through the vehicle-mounted system, and the rescue prompt information is sent outside the vehicle by controlling the vehicle alarm system alarm, so as to facilitate the preset contact person and other personnel outside the vehicle to rescue the driver and passengers in abnormal state.

[0103] When the driver and passenger are in the second abnormal state, the vehicle is controlled to drive to the target position to treat the driver and passenger in the second abnormal state, and the target position that can treat the driver and passenger in the second abnormal state needs to be determined. The specific process is as follows:

[0104] In some embodiments, step 103B includes:

[0105] Step 103Ba, obtaining environmental information of the current location of the vehicle.

[0106] Step 103Bb: determining that the environment of the current location is bad based on the environmental information, and determining a target location with a good environment from the surrounding locations of the current location according to pre-stored map data.

[0107] Step 103Bc, turning on the automatic driving mode, and controlling the vehicle to travel from the current position to the target position.

[0108] In specific implementation, when the target body temperature is lower than a preset second body temperature threshold, the target heart rate is lower than a preset second heart rate threshold, or the target respiration is lower than a preset second respiration threshold, it is determined that the driver and passenger are in the second abnormal state.

[0109] The preset second body temperature threshold is the body temperature threshold of the human body in the second abnormal state, the preset second heart rate threshold indicates that the heart rate is extremely slow, and the preset second breathing threshold indicates that the breathing almost stops, which can accurately determine whether the driver and passengers are in the second abnormal state.

[0110] For example, the preset second temperature threshold is 33°C, the preset second heart rate threshold is 40 times / minute, and the preset second breathing threshold is 10 times / minute. When the target temperature is less than 33°C, the target heart rate is less than 40 times / minute, and the target breathing is less than 10 times / minute, it is determined that the driver and passenger are in the second abnormal state.

[0111] In addition, in response to the target body temperature being less than a preset second body temperature threshold, it is determined that the occupant is in a second abnormal state. Alternatively, in response to the target heart rate being less than a preset second heart rate threshold and the target respiration being less than a preset second respiration threshold, it is determined that the occupant is in a second abnormal state. For example, when the target body temperature is less than 33°C, it is determined that the occupant is in a second abnormal state. Alternatively, when the target heart rate is less than 40 times / minute and the target respiration is less than 10 times / minute, it is determined that the occupant is in a second abnormal state.

[0112] When the driver and passenger are in the second abnormal state and the environment at the current location of the vehicle is bad, the vehicle is controlled to travel from the current location to the target location using the vehicle's automatic driving mode. The target location is a location with a good environment where the driver and passenger in the second abnormal state can be treated.

[0113] When the driver and passengers are in the second abnormal state, it is determined whether the current location is in a bad environment based on the environmental information of the current location of the vehicle. When the current environment of the vehicle is bad, the automatic driving mode is turned on. The target location with a good environment is determined, and the route between the current location and the target location is determined through path planning. The vehicle is controlled to travel from the current location to the target location according to the planned route, and the driver and passengers in the second abnormal state can be transported to the target location for treatment, avoiding life danger for the driver and passengers in the second abnormal state.

[0114] Through the above scheme, when the target body temperature is less than the preset second body temperature threshold, the target heart rate is less than the preset second heart rate threshold, and the target respiration is less than the preset second respiration threshold, it can be accurately determined that the driver and passenger are in the second abnormal state. When the driver and passenger are in the second abnormal state, and the current location of the vehicle is in a bad environment, the vehicle's automatic driving mode is used to control the vehicle to travel from the current location to the target location, and the driver and passenger in the second abnormal state can be transported to the target location for treatment, avoiding life danger to the driver and passenger in the second abnormal state.

[0115] In some embodiments, step 103Bb includes:

[0116] Step S1, taking the pre-stored permanent location of the driver and passenger as the first location.

[0117] Step S2, determining a target medical institution closest to the current location, and taking the location of the target medical institution as the second location.

[0118] Step S3, determining a first route between the current position and the first position and a first distance corresponding to the first route, and determining a second route between the current position and the second position and a second distance corresponding to the second route.

[0119] Step S4, in response to determining that the first distance is less than the second distance, taking the first position as a target position, and controlling the vehicle to travel from the current position to the target position along the first route.

[0120] Step S5, in response to determining that the second distance is less than the first distance, taking the second position as a target position, and controlling the vehicle to travel from the current position to the target position along the second route.

[0121] In specific implementation, in order to quickly transport the driver and passenger in the second abnormal state to a target location with a good environment and capable of receiving treatment, the target location closest to the current location is determined from the driver and passenger's permanent location and the target medical institution. The driver and passenger's permanent location is the driver and passenger's address location preset and stored in the vehicle, and the target medical institution is the medical institution closest to the current location.

[0122] A first route between the current location and the driver's and passenger's permanent location is determined by a path planning algorithm, and a first distance and a first travel time of the first route are determined. A second route between the current location and a target medical institution is determined by a path planning algorithm, and a second distance and a second travel time of the second route are determined.

[0123] For example, when the first distance is less than the second distance, the vehicle is controlled to travel from the current position to the permanent position of the driver and passenger according to the first route. When the second distance is less than the first distance, the vehicle is controlled to travel from the current position to the target medical institution according to the second route.

[0124] For another example, when the first driving time is less than the second driving time, the vehicle is controlled to drive from the current position to the permanent location of the driver and passenger according to the first route. When the second driving time is less than the first driving time, the vehicle is controlled to drive from the current position to the target medical institution according to the second route.

[0125] The target location is determined according to a preset target location type. For example, if the preset target location type is a residence, the vehicle is controlled to travel from the current location to the permanent location of the driver and passenger according to a first route. If the preset target location type is a medical institution, the vehicle is controlled to travel from the current location to the target medical institution according to a second route.

[0126] In addition, step 103Bb also includes: determining whether there are companions of the driver and passenger in the second abnormal state in the vehicle; in response to determining that there are companions in the vehicle, displaying the first position and the second position through the vehicle-mounted screen; in response to determining that a position determination instruction has been received, determining the target position from the first position and the second position according to the position determination instruction.

[0127] For example, when there is a companion in the vehicle, the first location and the second location are displayed on the vehicle screen, and the companion is prompted by voice to select a target location. When the companion clicks the first location on the screen, the first location is used as the target location. Alternatively, when the companion inputs "first location" by voice, the first location is used as the target location.

[0128] In addition, an alarm can be given in a preset manner during the process of controlling the vehicle to travel from the current position to the target position. For example, during the process of controlling the vehicle to travel from the current position to the target position, an alarm can be given in a preset manner at each preset time interval. In this way, during the process of the vehicle traveling to the target position, the alarm can be used to facilitate passers-by on the way to find the abnormal state of the driver and passengers on the vehicle and provide rescue. At the same time, the alarm can be given at each preset time interval, which can save energy and electricity to the greatest extent while facilitating passers-by to rescue the abnormal state of the driver and passengers, and ensure that the vehicle can travel to the target position.

[0129] Through the above scheme, the first route and the first distance between the current position and the permanent location of the driver and passengers are determined, and the second route and the second distance between the current position and the target medical institution are determined. By comparing the first distance and the second distance, the target position closest to the current position can be determined between the permanent location of the driver and passengers and the target medical institution, so that the vehicle can be quickly controlled to travel from the current position to the target position, so that the driver and passengers in the second abnormal state can receive rapid treatment and avoid life-threatening danger to the driver and passengers in the second abnormal state.

[0130] Through the above-mentioned embodiments, characteristic data of the driver and passenger are obtained. When the characteristic data is less than the preset characteristic threshold of the normal state, it is determined that the driver and passenger are in an abnormal state. The position where the driver and passenger are in the abnormal state is heated. In this way, when the characteristic data of the driver and passenger is less than the preset characteristic threshold of the normal state, it is possible to accurately detect that the driver and passenger are in an abnormal state. By heating the position where the driver and passenger are in an abnormal state, the driver and passenger in the abnormal state can be helped to return to the normal state in time, and emergency treatment can be performed on the driver and passenger in the abnormal state to avoid life-threatening situations due to being in the abnormal state for a long time.

[0131] It should be noted that the embodiments of the present disclosure may be further described in the following manner:

[0132] The disclosed embodiments can also be applied to long-distance travel scenarios. During a long-distance travel, it is determined whether the driver and passengers have symptoms of hypothermia. When the driver and passengers are in a state of hypothermia, emergency treatment is performed on the driver and passengers in a state of hypothermia, and the driver and passengers in a state of hypothermia are promptly helped to recover to a normal state, thereby avoiding life-threatening situations for the driver and passengers due to prolonged hypothermia.

[0133] The goal of the embodiments of the present disclosure is to provide an in-vehicle intelligent detection system that can monitor the physiological state of passengers, especially hypothermia, in real time in the harsh climate and complex environment of off-road enthusiasts and other long-distance drivers. When the system detects that the core body temperature of the passenger is lower than the hypothermia standard, it can automatically start the rewarming mechanism to quickly help the passenger restore normal body temperature through the insulated medical insulation space and related heating devices to avoid life-threatening situations caused by hypothermia. In addition, the embodiments of the present disclosure also provide intelligent rescue signal transmission and automatic driving return functions, so as to obtain external assistance as soon as possible in an emergency or move the vehicle seat belt away from the dangerous area.

[0134] 1. Specific implementation steps

[0135] Figure 2 FIG. 1 is a flow chart of the temperature loss protection method according to an embodiment of the present disclosure. Figure 2As shown, the hypothermia detection mode is started; the integrated sensor data is used to judge hypothermia according to the preset algorithm; it is judged whether the passenger is hypothermic (body temperature is lower than 35°C); when the passenger is not hypothermic, the body temperature is continued to be monitored; when the passenger is hypothermic, the hypothermia protection mode is activated. In addition, the hypothermia protection mode can be turned on manually or by voice command. After the hypothermia protection mode is activated, the insulation board extends out to create a closed space, the heating and pre-air conditioning system is started, and intelligent power management is performed at the same time; the PID algorithm dynamically adjusts the temperature to maintain at 37°C, the body temperature returns to the normal range (about 36-37°C), and the hypothermia protection mode is turned off to restore the original state in the car; the alarm system inside and outside the car is activated to send an emergency signal for help; the vehicle detects that the environment is harsh and the personnel are seriously hypothermic, and automatically returns.

[0136] 2. Human body temperature monitoring system

[0137] (1) Sensor selection

[0138] Infrared temperature sensor: A non-contact infrared temperature sensor can monitor the passenger's body temperature in real time by detecting the infrared radiation emitted by the passenger's body. The infrared temperature sensor is not blocked by clothing and can quickly obtain the passenger's body temperature data. It is flexible to install and will not cause discomfort to the passenger. It can be installed in the seat back area, the ceiling of the car or the inside of the door to ensure that the infrared temperature sensor can cover the passenger's upper body.

[0139] Heart rate sensor and respiratory sensor: Use patch-type or seat-integrated heart rate sensor and respiratory sensor. The heart rate sensor can be built into the seat armrest or seat surface to measure the heart rate in real time when in contact with the passenger's body. The respiratory sensor can be embedded in the seat back or seat cushion to assess the respiratory rate by detecting the passenger's chest or abdominal movement.

[0140] (2) Device installation

[0141] Seat embedded sensors: The seat is the core area for sensor installation. Body temperature sensors, heart rate sensors, and breathing sensors can be embedded in the seat surface, backrest, armrests, etc. to ensure direct or indirect contact with the passenger's body.

[0142] Sensors in other locations in the car: Infrared body temperature sensors can be placed on the roof, doors, or air-conditioning vents to ensure multi-angle coverage of passengers in the car. At the same time, sensors are installed near the driver's seat and the co-pilot seat to provide real-time monitoring of multiple passengers.

[0143] (3) Determination of hypothermia

[0144] 1) Sensor data collection

[0145] Different types of sensors will provide the system with physiological data of the passengers.

[0146] Body temperature sensor: Real-time measurement of passengers’ body temperature data (normal value is about 36.5℃-37℃), with special attention paid to whether the body temperature data is lower than 35℃.

[0147] Heart rate sensor: monitors the passenger's heart rate data (normal heart rate range is 60-100 beats / minute). When a passenger is hypothermic, the heart rate data will usually be lower than normal.

[0148] Respiratory sensor: detects the passenger's respiratory data (normal respiratory rate is 12-20 times / minute). When the body temperature drops, the respiratory data tends to slow down.

[0149] 2) Criteria for determining hypothermia

[0150] To judge the state of hypothermia, the following criteria are mainly used:

[0151] Core body temperature below 35°C: This is the main indicator of hypothermia.

[0152] Heart rate and breathing rate are below normal range: As body temperature drops, heart rate and breathing rate will slow down.

[0153] 3) Multi-sensor data fusion

[0154] In order to ensure the accuracy of the judgment, we cannot rely solely on body temperature data, but also need to combine other physiological data. The system will make hypothermia judgments by multi-sensor data fusion. The following are the specific steps:

[0155] ①Data preprocessing

[0156] Data cleaning: Since the sensor may be affected by external interference, the data needs to be filtered and cleaned first. For example, the error of the temperature sensor can be reduced by averaging the temperature data measured multiple times.

[0157] Data synchronization: The collection frequencies of heart rate data, respiration data, and body temperature data from the temperature sensor may be different. The data needs to be synchronized on the time axis to ensure that the data used for analysis are collected at the same time.

[0158] ②Multi-parameter discrimination algorithm

[0159] Logical rule engine: Based on the set physiological parameter thresholds, the system uses logical rules to make judgments. For example, when the body temperature data is lower than 35°C, the heart rate data is lower than 60 times / minute, and the breathing data is lower than 12 times / minute, the system will determine that the passenger is in a state of hypothermia.

[0160] ③Rule example:

[0161] When the body temperature data is <35℃, the heart rate data is <60 times / minute and the breathing data is <12 times / minute, it is determined that the passenger is in a state of hypothermia.

[0162] When the body temperature data is <33℃ or the heart rate is extremely slow and breathing stops, it is determined that the passenger is in a state of severe hypothermia.

[0163] 4) Continuous monitoring and temperature loss judgment logic

[0164] The system does not judge hypothermia based on a single sensor data, but performs continuous monitoring.

[0165] Threshold continuity detection: If the body temperature data is detected to be lower than 35°C, the system will continue to collect body temperature data for several minutes to prevent false alarms. If the body temperature data, heart rate data, and breathing data are still lower than the normal range within a few minutes, it is confirmed that the passenger is in a state of hypothermia.

[0166] 5) False alarm and redundant processing

[0167] In order to prevent false alarms, the system will consider a redundant judgment mechanism.

[0168] Cross-validation: Through cross-validation of multiple sensor data, the failure or abnormality of a single sensor can be ruled out. For example, even if the body temperature sensor detects low temperature, if the heart rate data and breathing data are normal, the system will not immediately trigger the hypothermia mode.

[0169] Abnormal data processing: For abnormal data that obviously does not conform to the physiological characteristics of the human body (such as sensor failure), the system will automatically ignore the abnormal data or request re-measurement.

[0170] 3. Thermal insulation medical space design

[0171] (1) Material selection

[0172] Thermal insulation board: A retractable thermal insulation board is installed between the trunk and the rear seats. The thermal insulation board uses high-efficiency thermal insulation materials (such as Mylar composite materials or multi-layer vacuum insulation panels) to effectively prevent heat loss between the car compartment and the trunk. When the heat loss protection mode is activated, the thermal insulation board will automatically extend to close the passage between the trunk and the car compartment, forming an independent insulation space.

[0173] (2) Structural design

[0174] Directly transform the trunk into a heat preservation space: The entire trunk is transformed into a heat preservation space. It is separated from the rear seats by an automatically retractable heat insulation board to form a relatively closed and heat preservation area.

[0175] Trunk heating device: A heating device, such as an electric heating plate or embedded heating module, is installed at the bottom of the trunk and powered by the vehicle power supply. The heating devices will be evenly distributed at the bottom of the trunk to ensure that the hypothermic person can feel continuous heating from the bottom when lying in the trunk.

[0176] (3) Air conditioning system:

[0177] Trunk air conditioning: To speed up the heating process, special air conditioning outlets are added to the trunk. These outlets are connected to the car's air conditioning system, but after the temperature protection mode is activated, the trunk temperature will be controlled separately to ensure that the temperature is quickly raised to a suitable range (around 37°C). The air conditioning can be set to hot air mode to directly heat the trunk.

[0178] (4)Automation function:

[0179] The thermal insulation board extends automatically: Once the passenger's body temperature is detected to be abnormal, the system will activate the hypothermia protection mode and automatically extend the thermal insulation board to isolate the trunk from the rear seats, forming a thermal isolation space.

[0180] Heating and air conditioning start simultaneously: After the heat insulation board is extended, the heating device and air conditioning system will start simultaneously. Through the synergistic effect of bottom heating and hot air, the trunk temperature can be quickly increased to help people with hypothermia return to normal body temperature.

[0181] 4. Temperature recovery part

[0182] (1) Heating module design

[0183] Electric blanket or heat-sensitive pad: The heat-insulating medical space is equipped with a low-power electric blanket or heat-sensitive pad, which is powered by the vehicle power supply to provide a stable heating effect. The electric blanket or heat-sensitive pad equipment is arranged at the bottom or side wall of the trunk to ensure that passengers can feel the warmth in the shortest time.

[0184] Far infrared heating technology: In order to achieve more efficient temperature recovery, the system can use far infrared heating technology, which uses the heat of the far infrared band to penetrate the human body and increase the temperature recovery speed. This heating method can not only heat the surface, but also penetrate into the muscle tissue to accelerate the recovery of body temperature.

[0185] (2) Temperature control

[0186] PID control algorithm: The temperature control module uses the PID (proportional-integral-differential) control algorithm to monitor the temperature changes in the space in real time and make dynamic adjustments to ensure that the temperature is maintained within the appropriate range of 37°C. The PID control algorithm can quickly increase the heating power when the temperature in the insulation space is too low, and gradually reduce the power when approaching the target temperature to prevent overheating.

[0187] PID control algorithm: Set rules in advance according to actual test data, adjust the temperature of the heating plate used to warm up the human body at each hypothermia temperature, as well as the air conditioning temperature, air volume, etc. After the sensor recognizes the human body temperature, it automatically adjusts to a specific gear.

[0188] 5. Emergency response and rescue linkage

[0189] (1) Automatic emergency signal transmission

[0190] When the system detects that a passenger is in a state of hypothermia and the rewarming mode is activated, the vehicle system will automatically send an emergency signal to the preset rescue system or emergency contact. The signal can be sent via satellite communication or mobile network and contains key data such as the vehicle's real-time location, passenger temperature and health status.

[0191] (2) Internal and external alarm systems

[0192] In an emergency, the vehicle can sound an audible alarm through the vehicle speaker or external alarm device, and the warning lights inside and outside the vehicle will automatically turn on to alert surrounding vehicles or people. At the same time, the vehicle system can be triggered to send an SOS signal to nearby vehicles to seek help.

[0193] (3) Autopilot return function

[0194] If the vehicle detects that the environment is bad and the person is suffering from severe hypothermia, the system will automatically activate the vehicle's autonomous driving mode and safely navigate the vehicle to the nearest safe point or medical institution. The autonomous driving return function relies on the vehicle's navigation system and sensors to plan the route, giving priority to the nearest and relatively safe route.

[0195] 6. Energy consumption and battery management

[0196] (1) Intelligent power management system

[0197] The operation of the heating module and the trunk medical insulation space will consume a lot of power from the vehicle power supply, so the system integrates an intelligent power management module. When the system detects that the vehicle is running in the reheating mode, it will give priority to allocating power to the heating module in the medical insulation space and ensure that the power supply of key functions of the vehicle (such as the engine and electronic control system) is not affected.

[0198] (2) Power monitoring and backup power supply

[0199] The system will continuously monitor the battery status of the vehicle. If the battery is insufficient to support the long-term operation of the medical insulation space, it will remind the driver or automatically start the energy-saving mode to reduce unnecessary power consumption. In addition, it can also be equipped with a dedicated backup power supply, such as a lithium battery pack, to power the medical insulation space in an emergency to ensure that the reheating process is not interrupted.

[0200] Beneficial effects of the embodiments of the present disclosure:

[0201] (1) Intelligent hypothermia monitoring and rewarming mechanism: The system can monitor passengers’ body temperature and physiological data in real time, automatically determine whether they have entered a hypothermic state, and take timely rewarming measures. This greatly improves the survival rate of passengers in extreme environments, especially for off-road enthusiasts who are in harsh environments for a long time, ensuring safety in emergency situations.

[0202] (2) Integrated thermal insulation medical space: By designing a medical thermal insulation space in the trunk area, it not only makes rational use of the space in the vehicle, but also provides an emergency environment that can quickly heat up and maintain a constant temperature at critical moments.

[0203] (3) Intelligent rescue linkage: The system can automatically send out a rescue signal to the outside world when an emergency is detected, and can combine with the automatic driving function to safely return the vehicle to the rescue site. This dual safety mechanism greatly shortens the time it takes for people with hypothermia to receive medical assistance.

[0204] (4) Energy efficiency optimization: Through intelligent power management, the temperature recovery process is ensured to not burden the vehicle's overall power system, thus achieving efficient and safe operation.

[0205] Through the above-mentioned embodiments, the disclosed embodiments will provide off-road enthusiasts with a vehicle health and safety method to help passengers gain a higher chance of survival and reduce the risk of hypothermia in extreme weather and environments.
