For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0032] The fields of vehicle engineering, sensor technology and emergency escape systems are important components of modern automobile technology. The field of vehicle engineering mainly involves the design, manufacture, maintenance and improvement of automobiles; the field of sensor technology mainly involves the research and development, production, application and optimization of sensors; the field of emergency escape systems mainly involves the design, manufacture, application and improvement of emergency escape equipment. The development of these technical fields is of great significance to improving the safety, reliability and comfort of automobiles.

[0033] In the existing technology, vehicles are usually equipped with some basic emergency escape equipment, such as seat belts, airbags, door escape handles, etc. In addition, some high-end models are also equipped with more emergency escape equipment, such as automatic unlocking function, roof escape window, etc. However, these existing emergency escape equipment often cannot work when the vehicle accidentally falls into the water, resulting in the driver and passengers being unable to escape and losing their lives.

[0034] The problems or shortcomings of the existing technology in this field mainly include the following aspects: First, the existing emergency escape equipment can usually only play a role when the vehicle collides or rolls over, but when the vehicle accidentally falls into the water, these devices often cannot play a role; second, the existing emergency escape equipment usually requires the driver and passengers to operate manually, but when the vehicle accidentally falls into the water, the driver and passengers often cannot operate these devices manually; finally, the existing emergency escape equipment usually does not reserve passenger escape passages, resulting in the driver and passengers being unable to escape from the vehicle.

[0035] In order to solve the technical problems existing in the above-mentioned prior art, the present application provides an escape control method, device, computer equipment and storage medium for a wading vehicle, which are described in detail using the following embodiments.

[0036] The execution subject of this application is the vehicle escape controller, which adopts a high level of waterproof strength, which can effectively prevent the electronic circuit controller from getting water in and ensure the normal operation of the vehicle. For example, the vehicle escape controller adopts IP68 level waterproof strength, which can effectively prevent the electronic circuit controller from getting water in and ensure the normal operation of the vehicle. The vehicle escape controller integrates a super capacitor to prevent the power supply harness of the escape controller from being broken.

[0037] The present application also includes an escape position design, such as a skylight or a trunk. The escape position corresponding to the skylight can also be circular, square, trapezoidal or triangular, etc., and the specific size and shape are not limited. The escape position corresponding to the trunk can also be square, trapezoidal or elliptical, etc., and the specific size and shape are not limited. The size design of the escape position is only an example here. For example, the escape position design corresponding to the skylight can be a circle with a diameter of 50 cm, and the escape position design corresponding to the trunk can be a cuboid with a length, width and height of 100 cm, 80 cm and 60 cm respectively.

[0038] Safety raft design: The safety raft pops out of the roof or trunk. The specific parameters of the safety raft can be determined in combination with the needs of the actual application scenario and are variable. This is only an example and is not limited. For example, the safety raft can be made of ABS material, and the size can be set to a rectangular block with a length of 150 cm, a width of 80 cm, and a thickness of 10 cm, and the buoyancy is 100 kg.

[0039] Automatic moving seat design: The onboard escape controller can control the seat to automatically move the passengers and the driver to the corresponding escape position. The movement of the seat can be achieved through an electric or hydraulic system, and the safety of the passengers and the driver must be ensured during the movement.

[0040] Sensor application: Body posture sensors (body left and right tilt angle, body front and rear tilt angle) are integrated around the vehicle to determine the position of the vehicle after it enters the water; face recognition camera sensors are used to detect the driver's mental state (attention concentration); optical sensors collect the driver's heart rate, blood pressure, and body temperature for real-time monitoring of the driver's physiological parameters. Biomedical signal processing equipment is used to receive and process data collected by sensors and analyze the driver's health status through built-in algorithms. The buoyancy sensor adopts a V-shaped structure and is installed at the bottom of the vehicle. When the vehicle enters the water, the buoyancy sensor will detect the rise in water level. After the comprehensive body posture sensor, face recognition camera sensor, and optical sensor signal algorithm are processed, it is judged that a dangerous situation has been reached.

[0041] Emergency escape system integration: Integrate the above technical means into a complete emergency escape system to achieve automatic response and passenger escape when the vehicle enters the water. The emergency escape system should consider its reliability and safety to ensure that it can work normally in an emergency.

[0042] One aspect of the present application provides an escape control method for a wading vehicle, which is implemented based on the above-mentioned emergency escape system. Figure 1 , Figure 1 FIG. 1 is a flow chart of an exemplary embodiment of the present application showing a method for controlling the escape of a water-wading vehicle. Figure 1 As shown, the method comprises the following steps:

[0043] S110: In response to the collection signal, collect current state information of the current driver.

[0044] Among them, the collected signal is the signal generated by the buoyancy sensor when it senses the current liquid level change difference in the vehicle's environment and reaches a preset threshold; the current status information includes the current driver's physical status information, driving status information, and vehicle posture status information.

[0045] For example, by using a buoyancy sensor to detect the wading conditions of a vehicle, the wading conditions of the vehicle can be detected in time, thereby improving the timeliness of emergency escape. The buoyancy sensor can be installed at the bottom of the vehicle. When the vehicle enters the water, the buoyancy sensor will detect the rise in the water level and transmit the signal to the on-board escape controller. The roof and / or the trunk are provided with a pop-up safety raft. The design of the safety raft should take into account its buoyancy and stability to ensure that passengers can remain stable and safe during the escape process. The safety raft is set on the roof and / or the trunk because the roof is the skylight position and the trunk has a rear window glass, both of which are preset escape positions.

[0046] S120: If the current state information belongs to the escapeable state information set, a target escape strategy is determined according to the liquid level change difference.

[0047] The state information belongs to a state information set, and the state information set includes an escapeable state information set and an inescapable state information set.

[0048] Exemplarily, the state information belonging to the escapeable state information set is the state that currently satisfies the escape condition. The target escape strategy includes controlling whether to move a designated seat and controlling whether to eject a safety raft. The liquid level change difference is the difference between the current liquid level value and the initial liquid level value, and the initial liquid level value is 0.

[0049] S130: Control the designated seat and safety raft based on the target escape strategy.

[0050] Among them, the designated seats are seats occupied by people.

[0051] For example, based on the target escape strategy, the designated seats can be controlled to move. Combined with the above escape positions, it can be seen that the front seats move to the escape positions corresponding to the sunroof, and the rear seats move to the escape positions corresponding to the trunk. The safety raft is also installed at the sunroof (i.e., the roof) and the trunk.

[0052] The vehicle is equipped with an escape position, such as a sunroof or trunk. The position design of the sunroof or trunk should take into account the overall structure of the vehicle and the escape needs of the passengers to ensure that the passengers can escape smoothly. The escape position corresponding to the sunroof is the escape position of the front seats, and the escape position corresponding to the trunk is the escape position of the rear seats.

[0053] Under the premise that the vehicle is provided with a buoyancy sensor and a safety raft, this embodiment collects the current state information of the current driver in response to the collection signal, and when the current state information belongs to the escapeable state information set, determines the target escape strategy according to the liquid level change difference, and finally controls the designated seat and the safety raft according to the target escape strategy to enable the driver to escape from the vehicle that has fallen into the water.

[0054] By arranging a safety raft on the vehicle and later controlling the safety raft to enable the driver to escape, the situation in which the emergency escape equipment in the prior art cannot function in water is avoided.

[0055] At the same time, the target escape strategy is determined according to the difference in liquid level changes, and the designated seats and safety raft are controlled directly based on the target escape strategy, so that the movement of the designated seats and the ejection of the safety raft can be automatically controlled without manual operation by the driver, thereby avoiding the situation where the danger is aggravated by improper operation of the driver in an emergency. Even in the scenario where the driver is unable to operate due to injury, this solution can realize the driver's escape by automatically controlling the designated seats and safety raft, thereby greatly improving the efficiency of emergency escape after falling into the water.

[0056] In some embodiments, it is described in detail how to determine the target escape strategy steps according to the liquid level change difference, such as Figure 2 As shown, Figure 2 is based on Figure 1 The exemplary embodiment shown is a flow chart of another escape control method for a wading vehicle. Figure 1 The S120 shown further includes S210 to S240, which are described in detail as follows:

[0057] S210: Monitor whether the current liquid level change difference reaches a preset threshold.

[0058] The preset threshold includes a first preset threshold, a second preset threshold and a third preset threshold, and the first preset threshold is smaller than the second preset threshold, and the second preset threshold is smaller than the third preset threshold;

[0059] For example, the liquid level change difference is the difference between the current liquid level value and the initial liquid level value, and the initial liquid level value is 0. The vehicle falling into the water is a dynamic process, and the corresponding liquid level change difference also increases gradually. Different sizes of liquid level change differences also correspond to the severity of the current vehicle wading. Different degrees of wading correspond to different escape strategies. Therefore, it is necessary to monitor the current liquid level change difference in real time to determine the current optimal escape strategy.

[0060] S220: If it is monitored that the current liquid level change difference reaches a first preset threshold, determining the target escape strategy as a strategy for controlling the movement of a designated seat.

[0061] The first preset threshold is the dividing value between normal wading and light wading. Normal wading does not require an early warning.

[0062] Exemplarily, if the current liquid level change difference reaches the first preset threshold, it indicates that the current vehicle is in light wading and a light warning is required. Combined with the warning level classification and its corresponding escape strategy table shown in Table 1 below, it can be seen that the escape strategy for light warning is a strategy that characterizes controlling the movement of a designated seat.

[0063] Table 1 Warning method classification and corresponding escape strategy table

[0064]

[0065] S230: If it is monitored that the current liquid level change difference reaches a second preset threshold, the target escape strategy is determined to be characterized by controlling the movement of a designated seat and outputting a pop-up confirmation prompt.

[0066] The pop-up confirmation prompt is used to prompt the current driver to determine whether the safety raft needs to be popped out.

[0067] Exemplarily, the second preset threshold is the boundary value between light wading and moderate wading. If the current liquid level change difference reaches the second preset threshold, it indicates that the current vehicle is in moderate wading, and a moderate warning is required. As shown in Table 1 above, the escape strategy of the moderate warning is to control the movement of the designated seat and output a pop-up confirmation prompt.

[0068] S240: If it is monitored that the liquid level change difference reaches a third preset threshold, the target escape strategy is determined to be controlling the movement of a designated seat and the ejection of a safety raft.

[0069] Among them, the third preset threshold is the dividing value between moderate wading and severe wading.

[0070] Exemplarily, if the current liquid level change difference reaches the third preset threshold, it indicates that the current vehicle is in severe wading, and a severe warning or a danger warning is required. As shown in Table 1 above, the escape strategy for the severe warning and the danger warning is characterized by controlling the movement of the designated seat and outputting a pop-up confirmation prompt.

[0071] This embodiment subdivides the corresponding target escape strategy when the current liquid level change difference reaches different preset thresholds, enriching and improving the technical solution. By using three preset thresholds to divide the liquid level change difference into three situations that require early warning, it is possible to quickly determine the most matching target escape strategy based on the preset range corresponding to the liquid level change difference, thereby achieving timely control of the designated seat and safety raft based on the target escape strategy to help the driver escape, greatly saving the escape reaction time, further saving the escape time, and improving the efficiency of emergency escape.

[0072] In some embodiments, the preset threshold also includes a fourth preset threshold that is greater than the third preset threshold; the escape strategy is introduced in detail and also includes a situation where an emergency call is made, which is specifically introduced as follows: if it is monitored that the current liquid level change difference reaches the fourth preset threshold, the target escape strategy is determined to represent the control of the movement of the designated seat and the ejection of the safety raft, and the current position information of the vehicle and the information of the people in the vehicle are sent to the emergency rescue center to make an emergency call.

[0073] Among them, the fourth preset threshold is the dividing value between severe warning and danger warning.

[0074] Exemplarily, when it is monitored that the current liquid level change difference reaches the fourth preset threshold, as shown in Table 1 above, in addition to controlling the movement of the designated seat and the ejection of the safety raft, the target escape strategy also includes automatically calling the emergency rescue center, and at the same time sending the vehicle's current location information and the information of the people in the vehicle to the emergency rescue center, saving rescue time and cost.

[0075] Among them, the emergency call is realized based on the 5G communication module, which is integrated in the vehicle-mounted T-BOX (Telematics BOX), that is, the vehicle-mounted networking system. The 5G communication module integrated in the T-BOX can adopt Huawei's 5G communication module, which has an uplink rate of up to 1Gbps and a downlink rate of up to 2Gbps, and can obtain the driver's health status in real time. The escape controller exchanges information with the emergency rescue center through the vehicle networking system integrated with the 5G communication module.

[0076] This embodiment determines the target escape strategy to control the movement of designated seats and the ejection of the safety raft, and sends the current position information of the vehicle and the information of the people in the vehicle to the emergency rescue center for emergency call, thereby realizing timely calling for help from the emergency rescue center in an emergency situation. At the same time, the vehicle position information and the information of the people in the vehicle are sent to save the rescue team's search time and improve the rescue efficiency.

[0077] In some embodiments, Figure 3 As shown, it details how to control the designated seats and safety rafts based on the target escape strategy. Figure 3 is based on Figure 1 The exemplary embodiment shown is a flow chart of another long-term driving safety warning method. Figure 1 The S130 shown further includes S310 to S320, which are described in detail as follows:

[0078] S310: Monitor the strength of the electrical signal generated by the buoyancy sensor due to sensing the difference in liquid level changes in the vehicle's environment.

[0079] Among them, the buoyancy sensor adopts a V-shaped structure and is installed at the bottom of the vehicle. When the vehicle enters the water, the buoyancy sensor will detect the rising water level.

[0080] For example, the buoyancy sensor will feel the pressure generated by the water after entering the water, and the buoyancy sensor will convert the pressure into an electrical signal. The deeper the water level, the greater the pressure and the stronger the amplitude of the electrical signal.

[0081] S320: If the intensity value of the monitored electrical signal reaches a preset intensity value, the backup data link is enabled, and based on the backup data link and the original data link, a corresponding control instruction specified by the target escape strategy is sent.

[0082] Among them, if the intensity value of the monitored electrical signal reaches a preset intensity value, it means that the vehicle has reached a light wading state.

[0083] Exemplarily, the backup data link is enabled, and then the corresponding control instructions specified by the target escape strategy are sent simultaneously through the backup data link and the original data link to ensure that the control instructions can be sent to the corresponding device to avoid the situation where the original data link is disconnected due to falling into the water.

[0084] This embodiment monitors the strength value of the electrical signal generated by the buoyancy sensor in real time to determine whether to enable the backup data link. By monitoring the strength value of the electrical signal, the vehicle's wading situation can be determined intuitively and quickly, and then the data link can be accurately determined. At the same time, by enabling the backup data link, and based on the backup data link and the original data link, the corresponding control instructions specified by the target escape strategy are sent, and the data transmission is guaranteed by adding links. At the same time, since the backup data link is not enabled at the moment of falling into the water, the situation where the data link is cut off due to the large impact force at the moment of falling into the water can be avoided, thereby improving the feasibility of data transmission to the corresponding device.

[0085] In some embodiments, the situation where the current device information belongs to the inescapable state information set is described in detail. The method also includes:

[0086] If the current state information belongs to the unable to escape state information set, the real-time information of the vehicle is recorded; the real-time information includes vehicle condition change information and vehicle body environment change information.

[0087] Exemplarily, when the current state information belongs to the inescapable state information set, it indicates that the vehicle has reached an inescapable state, and the vehicle condition change information and vehicle body environment change information are recorded.

[0088] The real-time information, current status information, and vehicle occupant information are stored in a preset fixed hard disk, and the vehicle's current location and occupant information are sent to an emergency rescue center.

[0089] For example, the preset fixed hard disk is a separate storage hard disk for storing information, and is independently and detachably arranged in the vehicle. The surface of the preset fixed hard disk is made of waterproof and anti-collision materials. Sending the current location and the information of the people in the vehicle to the emergency rescue center facilitates the rescue center to salvage the vehicle. And later, after the vehicle is damaged, the cause of the accident can be analyzed based on the information stored in the preset fixed hard disk.

[0090] When it is determined that escape is impossible, the vehicle will move the seats of the people in the car accordingly, open the glass of the escape position (i.e. the skylight and rear window mentioned above), and pop out the corresponding safety raft for humanitarian rescue. In order to achieve this humanitarian rescue, especially when the people in the car are unconscious due to the huge pressure difference at the moment of falling into the water, the seats are made of the same material as the safety raft (airbag), and a binding device is set on the seat to fix the person on the seat. After the person and the seat are moved to the escape position, the seat and the person are directly popped out together, and the seat drives the person on it to float to the surface. With this setting, even if the person is unconscious or cannot be rescued, the seat acting as a safety raft can float on the water together, bringing more possibilities for survival.

[0091] When implemented specifically, it can be combined with the backup data link in the above embodiment. Since the height of falling into the water is too high, the user will be unconscious due to the excessive impact force at the moment of entering the water (or unconscious due to the airbag being deployed). Pressure sensors are provided at the sunroof and trunk of the car, and the pressure sensors are also connected to the mechanical switches of the sunroof and trunk. That is, when the pressure sensors at both locations detect the pressure of the preset pressure value, the mechanical switches of the sunroof and trunk will be opened, and the backup data link will also be triggered. The binding device on the seat will be controlled first (a common personnel fixing device, similar to the pressure fixing in an amusement park, where the two sides of the seat are preferably fixed by hugging to avoid crushing the head). After fixing the person on the seat, the seat is moved to the escape position and popped out. The significance of opening the mechanical switch is that if the backup data link is disconnected from the original data link, the sunroof and trunk can also be opened through the mechanical switch, thereby buying time for the user to escape.

[0092] This embodiment records the real-time information of the vehicle, stores the real-time information, current status information, and the information of the occupants of the vehicle in a preset fixed hard disk, and sends the current location of the vehicle and the information of the occupants to the emergency rescue center. This further refines the processing method when the current status information belongs to the set of state information that cannot escape, enriching and improving this solution.

[0093] In some embodiments, Figure 4 As shown, how to determine the escapeable state information set and the inescapable state information set is described in detail. Figure 4 is based on Figure 1 The exemplary embodiment shown is a flow chart of another long-time driving safety warning method. The method also includes S410 to S420, which are described in detail as follows:

[0094] S410: Using the body state information, driving state information, and posture state information as coordinate axes of different dimensions, respectively, to construct an initial coordinate system.

[0095] For example, the physical state information is used as the X-axis, including heart rate parameters, blood pressure parameters and body temperature parameters, to characterize the current driver's physical health; the driving state information is used as the Y-axis, including the driver's concentration level, to characterize the current driver's mental state; the posture state information is used as the Z-axis, to characterize the current vehicle body front and back left and right tilt state score. There is no restriction on which information is used as which coordinate axis, which is only an example and not specifically limited.

[0096] S420: According to the historical state information, coordinate points corresponding to each historical state information are drawn in the initial coordinate system.

[0097] Among them, since it is a rare case that a single driver falls into the water, the historical status information here is the historical status information of the entire network falling into the water.

[0098] Exemplarily, coordinate points corresponding to the historical state information are obtained on the initial coordinate system according to the historical body state information, historical driving state information, and historical posture state information. When a certain amount of data is collected, n data points can be formed in the three-dimensional coordinate system.

[0099] S430: Determine two clusters in the initial coordinate system according to the multiple coordinate points obtained by drawing.

[0100] The clusters include escapable clusters and inescapable clusters. The escapable clusters correspond to an escapable state information set, and the inescapable clusters correspond to an inescapable state information set.

[0101] Exemplarily, the escapeable clusters correspond to those that meet the escape conditions, and the inescapable clusters correspond to those that do not meet the escape conditions.

[0102] This embodiment uses body state information, driving state information, and posture state information as coordinate axes of different dimensions to construct an initial coordinate system, and then plots the historical state information of the current driver in the initial coordinate system to obtain corresponding coordinate points; further, two clusters are determined based on the plotted coordinate points, and corresponding state information sets are determined based on the clusters. This achieves the establishment of an escapeable state information set and an inescapable state information set based on historical state information, further improving this technical solution.

[0103] At the same time, when determining the clustering clusters, the current driver's physical state information, driving state information and posture state information are fully combined to avoid the omission of historical state information, making the obtained clustering clusters more accurate, thereby making the state information set determined according to the clustering clusters more accurate and comprehensive, thereby improving the accuracy of the solution.

[0104] In some embodiments, Figure 5As shown, it details how to determine the state information set to which the current state information belongs. Figure 5 is based on Figure 1 The exemplary embodiment shown is a flow chart of another long-time driving safety warning method. The method also includes S510 to S520, which are described in detail as follows:

[0105] S510: Determine the target coordinate point corresponding to the current state information in the coordinate system, and calculate the distance value between the target coordinate point and the centers of the two clusters.

[0106] Among them, each cluster has a center point, and the center distance value is the distance value between the target coordinate point and the center point of each cluster.

[0107] For example, the body state information, driving state information, and posture state information in the current state information are digitized, and the three digitized values ​​are respectively mapped to the three axes in the coordinate system to obtain a coordinate point on the coordinate system, which is the target coordinate point. Combined with the coordinate system, the distance value between the target coordinate point and the center point of the two clusters is calculated as the center distance value (here the absolute value is taken), thereby obtaining two center distance values.

[0108] S520: The cluster corresponding to the minimum center distance value is used as the target cluster corresponding to the target coordinate point.

[0109] Among them, the minimum center distance value is the minimum center distance value. The center distance value represents the distance relationship between the target coordinate point and the cluster cluster. The minimum center distance value means that the cluster cluster corresponding to the minimum center distance value is closest to the target coordinate point.

[0110] Exemplarily, the two center distance values ​​are compared to determine the minimum center distance value, and then the cluster corresponding to the minimum center distance value is used as the target cluster corresponding to the target coordinate point. That is, the cluster closest to the target coordinate point is selected as the corresponding target cluster.

[0111] S530: Using the state information set corresponding to the target cluster as the state information set to which the target coordinate point belongs.

[0112] Exemplarily, the state information set corresponding to the target cluster is used as the target state information set to determine the state information set corresponding to the current state information.

[0113] When a new data point is added (i.e., a new target coordinate point is added), it is determined which cluster the position of the data point is closest to. No calculation is required, and the state information set corresponding to the cluster is reused to determine whether the current driver meets the escape condition.

[0114] This embodiment refines the determination of the state information set to which the current state information belongs, and further improves the technical solution; by converting the current state information into a target coordinate point in a coordinate system, and calculating the center distance value between the target coordinate point and the cluster cluster, the cluster cluster closest to the target coordinate point is determined, thereby quickly determining the state information set to which the current state information belongs. The solution is converted into a simple mathematical calculation, thereby greatly improving the data processing efficiency of determining the state information set corresponding to the current state information, and further improving the data processing efficiency of the overall solution. In addition, the mathematical calculation method of calculating the center distance value and comparing the size makes data processing more accurate, thereby improving the accuracy rate.

[0115] In some embodiments, Figure 6 As shown, it is introduced in detail how to determine the target coordinate point corresponding to the current state information in the coordinate system. Figure 6 is based on Figure 5 The exemplary embodiment shown is a flow chart of another long-term driving safety warning method. The method is as follows Figure 5 The further description of the sub-step of determining the target coordinate point corresponding to the current state information in the coordinate system in S510 shown includes S610 to S640, which are described in detail as follows:

[0116] S610: Multiply the value of each parameter in the body state information by the weight corresponding to each parameter, and sum the obtained products to obtain a first numerical value corresponding to the body state information.

[0117] The physical state information includes heart rate parameters, blood pressure parameters and body temperature parameters. The driver's physical state information is obtained by an optical sensor.

[0118] Exemplarily, the physical state information includes heart rate parameters, blood pressure parameters, and body temperature parameters. Table 2 below shows the classification of preset heart rate parameters, blood pressure parameters, and body temperature parameters.

[0119] Table 2 Classification table of physical status information

[0120]

[0121] The collected heart rate, blood pressure and body temperature values ​​are matched with the above Table 2 to determine the level of the current driver's heart rate, blood pressure and body temperature. Since each level of each parameter corresponds to a score, the heart rate score, blood pressure score and body temperature score can be obtained. The preset weights of each score are multiplied with each score, and the products are added to finally obtain the physical health parameter score (i.e., the first value). The calculation formula is:

[0122] Physical health parameter score (full score 100 points) = 0.4*heart rate score + 0.4*blood pressure score + 0.2*body temperature score

[0123] Among them, the weight of the heart rate score and the blood pressure score are both 0.4, and the weight of the body temperature score is 0.2.

[0124] S620: Match the degree value of the attention concentration parameter in the driving state information with a preset degree range, and obtain a preset value corresponding to the successfully matched preset degree range as a second value corresponding to the driving state information.

[0125] Among them, the driving state information includes the concentration level. The driver's mental state (concentration level) is obtained by the face recognition camera. Based on the facial image frame, the current driver's concentration level can be quickly determined. According to Table 3 below, the level corresponding to the concentration level in the facial recognition model can be known. Thus, the driving state information including the concentration level is obtained.

[0126] Exemplarily, the following Table 3 shows the classification levels corresponding to the preset concentration levels.

[0127] Table 3: Driving status information level table

[0128] Concentration Highly concentrated Moderate concentration Mild concentration Not focused

[0129] The degree level of the attention concentration parameter in the driving state information is matched with the preset degree level, and a preset value corresponding to the successfully matched preset degree level is obtained as a second value corresponding to the driving state information.

[0130] S630: multiplying the value of each parameter in the posture state information by the weight corresponding to each parameter, and summing up the obtained products to obtain a third value corresponding to the posture state information.

[0131] The posture state information includes the vehicle body front and rear tilt parameters and the vehicle body left and right tilt parameters.

[0132] For example, the vehicle body (front and rear) and (left and right) tilt states are determined by the vehicle body posture sensor to determine the current vehicle front and rear left and right tilt angles and whether the personnel meet the escape conditions. The calculation formula is:

[0133] The third value (full score 100 points) = 0.5 * body front and rear tilt state score + 0.5 * body left and right tilt state score

[0134] The weight of the body front and rear tilt state score is 0.5, the body front and rear tilt parameters match the preset front and rear tilt parameters, and the score corresponding to the successfully matched preset front and rear tilt parameters is the body front and rear tilt state score. The weight of the body left and right tilt state score is also 0.5, the body left and right tilt parameters match the preset left and right tilt parameters, and the score corresponding to the successfully matched preset left and right tilt parameters is the body left and right tilt state score.

[0135] S640: Plot points in the coordinate system based on the first value, the second value, and the third value to determine a target coordinate point corresponding to the current state information in the initial coordinate system.

[0136] Exemplarily, according to the first value, the second value and the third value as the values ​​of each axis in the coordinate system, a point in the coordinate system is obtained, and the point is the target coordinate point corresponding to the current state information in the coordinate system. It should be noted that since the coordinate system is obtained according to the initial coordinate system, and the initial coordinate system is established according to the body state information, the driving state information, and the posture state information, respectively, as coordinate axes of different dimensions. Therefore, the first value corresponds to the value of the coordinate axis where the body state information is located, the second value corresponds to the value of the coordinate axis where the driving state information is located, and the third value corresponds to the value of the coordinate axis where the posture state information is located.

[0137] This embodiment involves a variety of computer sensors providing a large amount of data to the escape controller, including: face recognition camera sensor, optical sensor, body posture sensor, buoyancy sensor, so that the escape controller can make accurate judgments on the driver's physical status information (heart rate, blood pressure, body temperature), concentration level (facial state) and the current danger level of entering the water (body left and right tilt angle, front and rear tilt angle, water level depth).

[0138] This embodiment refines the steps of determining the target coordinate point corresponding to the current state information in the coordinate system, and further improves the technical solution. The physical state information, driving state information, and posture state information in the current state information are numerically processed to obtain three numerical values, and then points are drawn in the coordinate system based on the three numerical values, thereby determining the target coordinate point corresponding to the current state information in the coordinate system. By numerically processing the information, the corresponding target coordinate point is quickly and accurately drawn in the coordinate system, thereby improving the speed and accuracy of data processing.

[0139] At the same time, when performing numerical processing, the parameters included in each information and the weight ratio of each parameter are fully combined. By multiplying the parameter value with the weight and then summing them up, while fully considering each information including the parameters and combining the weight ratio, the numerical processing is more accurate while ensuring data completeness.

[0140] The available warning methods for this solution include: vision (pop-up warning signals on the instrument panel, HUD, central control screen, etc., similar to the automatic driving function), hearing (alarm sounds from the audio system in the cockpit, headrest speakers, etc.), and the warning method can be based on the escape controller's final assessment of the current water wading situation to issue a single warning or a combined warning of at least two warning methods.

[0141] This solution converts the analog signals collected by the buoyancy sensor, body posture sensor, face recognition camera sensor, and optical sensor into electrical signals, and transmits them to the IO port of the escape controller through the wiring harness. The escape controller performs algorithm processing based on these electrical signals to see whether they exceed the danger threshold (that is, the corresponding first preset threshold); if exceeded, the escape controller will send corresponding control instructions to the seat controller, instrument panel, horn, and safety raft. When it exceeds the fourth preset threshold, it will be reported to the emergency rescue center through 5G-BOX.

These measures are all automatically performed without manual operation by the driver and the passengers, thereby improving the reliability of the technology.

[0155] The vehicle of the present invention is designed with reserved passenger escape passages, such as a sunroof or a trunk, so that when the vehicle accidentally falls into the water, passengers can escape smoothly through these passages, avoiding the problem of being unable to escape from the vehicle due to the lack of reserved passenger escape passages in the prior art.

In the field of vehicle engineering, this technical solution can greatly improve the safety of the vehicle, especially in the case of accidental fall into the water, it can effectively ensure the escape of the driver and passengers. This will greatly improve consumers' trust and satisfaction with automobile brands and promote the healthy and rapid development of the automobile industry. In the field of sensor technology, this technical solution can promote the further development of sensor technology.

[0159] It should be noted that the escape control device for a water-wading vehicle provided in the above embodiment and the escape control method for a water-wading vehicle provided in the above embodiment belong to the same concept, wherein the specific manner in which each module and unit performs operations has been described in detail in the method embodiment and will not be repeated here.

In RAM 803, various programs and data required for system operation are also stored. CPU 801, ROM 802 and RAM 803 are connected to each other through bus 804. Input / output (I / O) interface 805 is also connected to bus 804.

[0163] The following components are connected to the I / O interface 805: an input section 806 including a keyboard, a mouse, etc.; an output section 807 including a cathode ray tube (CRT), a liquid crystal display (LCD), etc., and a speaker, etc.; a storage section 808 including a hard disk, etc.; and a communication section 809 including a network interface card such as a LAN (Local Area Network) card, a modem, etc. The communication section 809 performs communication processing via a network such as the Internet.

[0166] Beneficial effect: Under the premise that the vehicle is equipped with a buoyancy sensor and a safety raft, the current state information of the current driver is collected in response to the collection signal, and when the current state information belongs to the escapeable state information set, the target escape strategy is determined according to the liquid level change difference, and finally the designated seat and the safety raft are controlled according to the target escape strategy to enable the driver to escape from the vehicle that has fallen into the water.

[0167] By arranging a safety raft on the vehicle and later controlling the safety raft to enable the driver to escape, the situation in which the emergency escape equipment in the prior art cannot function in water is avoided.

[0168] At the same time, the target escape strategy is determined according to the difference in liquid level changes, and the designated seats and safety raft are controlled directly based on the target escape strategy, so that the movement of the designated seats and the ejection of the safety raft can be automatically controlled without manual operation by the driver, thereby avoiding the situation where the danger is aggravated by improper operation of the driver in an emergency. Even in the scenario where the driver is unable to operate due to injury, this solution can realize the driver's escape by automatically controlling the designated seats and safety raft, thereby greatly improving the efficiency of emergency escape after falling into the water.
