[0087] The application provides a method for preventing submersion, a system for preventing submersion and a vehicle. The method for preventing submersion, the system for preventing submersion and the vehicle of the application are described in detail below with reference to the drawings. The features in the following embodiments and implementation manners can be combined with each other without conflict.

[0088] A vehicle includes a system for preventing submersion for protecting passengers from being injured by sliding in the vehicle when the vehicle is braked or parked in an emergency.

[0089] Figure 1 The structure diagram of an exemplary embodiment of the system for preventing submersion of the application is shown. In the embodiment shown, Figure 1 In the embodiment shown, the system for preventing submersion 81 includes a submersion-preventing assembly 82 assembled on a seat of the vehicle and a controller 85 connected to the submersion-preventing assembly 82. The submersion-preventing assembly 82 is used to increase the friction between the seat and the passengers, and the submersion-preventing assembly 82 is arranged higher than the seat, which is beneficial to protect the passengers from being injured by sliding forward and hitting other parts of the vehicle in the case of emergency braking or parking, and to improve the safety of the passengers in the vehicle. The controller 85 connected to the submersion-preventing assembly 82 can be used to control the height and submersion-preventing performance of the submersion-preventing assembly 82, so as to realize different degrees of submersion-preventing performance of the submersion-preventing assembly 82 under different conditions, and to improve the comfort and safety of the passengers in the vehicle.

[0090] In some embodiments, the submersion-preventing assembly 82 includes a mounting skeleton 86, a moving bracket 84 and a plurality of protrusions 87, wherein the mounting skeleton 86 is attached to the seat, the moving bracket 84 is arranged on the mounting skeleton 86 and can move up and down relative to the mounting skeleton 86, and the plurality of protrusions 87 are arranged on the surface of the mounting skeleton 86 and used to contact the human body. The controller 85 is electrically connected to the moving bracket 84 and used to control the height of the moving bracket 84. The mounting skeleton 86 is fixedly arranged on the seat and used to fix the passengers on the seat, which is beneficial to protect the passengers from being injured by sliding forward and hitting the vehicle in the case of sudden change of the vehicle speed. The plurality of protrusions 87 arranged on the surface of the mounting skeleton 86 can be used to massage the passengers, which is beneficial to improve the comfort of the passengers in the vehicle. The controller 85 connected to the moving bracket 84 is used to control the height of the moving bracket 84, so that the moving bracket 84 can be adjusted in height in real time according to the driving condition of the vehicle, to adapt to the safety degree and the comfort degree required by the vehicle in real time.

[0091] In some embodiments, the height of the passengers in the vehicle can also be adjusted by arranging a plurality of protrusions 87 on the moving bracket 84 and adjusting the height of the plurality of protrusions 87.

[0092] Figure 2An exemplary flowchart of the anti-submersion method is shown. In Figure 2 In the embodiment shown, the anti-submersion method is applied to the anti-submersion system 81, including steps S11-S14:

[0093] Step S11, obtaining driving information; the driving information includes vehicle driving condition information and / or driving environment information. In some embodiments, the vehicle driving condition information can be used to represent the driving speed of the vehicle, the rotating speed of the vehicle engine, and other working conditions of the vehicle itself. The driving environment information is used to represent the environmental conditions of the vehicle during driving, such as road surface, field of view, and weather conditions, etc.

[0094] Step S12, determining a safety detection score representing the safety condition of the vehicle according to the driving information. The safety detection score is determined according to the vehicle driving condition information and / or the driving environment information. Different working conditions of the vehicle and / or different environmental conditions the vehicle is in have different safety levels. The safety detection score represents the safety level of the vehicle driving. Displaying the working condition of the vehicle through the score is conducive to more intuitively judging whether the vehicle is safe.

[0095] Step S13, if the safety detection score is greater than a safety setting score, controlling the anti-submersion assembly 82 to be in a submersion prevention state. Step S14, if the safety detection score is not greater than the safety setting score, controlling the anti-submersion assembly 82 to be in a safety state, and the height of the anti-submersion assembly 82 in the submersion prevention state is higher than the height in the safety state.

[0096] In some embodiments, the higher the safety detection score, the lower the safety. In some embodiments, when adjusting the state of the anti-submersion system 81, the controller 85 judges the safety condition of the vehicle driving by comparing the detected safety detection score and the set safety setting score, and then controls the state of the anti-submersion assembly 82. When the safety detection score is greater than the safety setting score, the controller 85 judges that the driving condition of the vehicle at this time is no longer in a safety condition, and therefore the protection of the vehicle to the passengers needs to be improved. At this time, the height of the anti-submersion assembly 82 is raised. A height threshold can be set to distinguish between the submersion prevention state and the safety state. At this time, the height adjustment of the anti-submersion assembly 82 reaches the height threshold, so that the anti-submersion assembly 82 is in the submersion prevention state, which is conducive to strengthening the limitation of the anti-submersion assembly 82 to the position of the passengers on the seat, and can effectively prevent the passengers from sliding forward on the seat to cause injury, and is conducive to improving the safety of riding.

[0097] When the safety detection score is not greater than the safety setting score, the controller 85 determines that the driving condition of the vehicle is in a safe state. In the safe state of the vehicle, the comfort of the vehicle relative to the passengers can be preferentially ensured. At this time, the height of the anti-submersion assembly 82 is controlled to be lowered, so that the anti-submersion assembly 82 is in a safe state. In some embodiments, the height of the anti-submersion assembly 82 can be controlled to be lower than the height threshold, so that the anti-submersion assembly 82 is in a safe state, which is beneficial to enhance the comfort of the passengers riding the vehicle. In some embodiments, according to different safety detection scores, the anti-submersion assembly 82 can be controlled to adjust to different heights. The safe state corresponds to a plurality of safety detection scores, and the anti-submersion state corresponds to a plurality of safety detection scores. In this way, the adjustment can be more accurate, and the safety and comfort can be better balanced. The higher the safety detection score, the lower the safety of the vehicle driving, and therefore the anti-submersion assembly 82 is controlled to be raised to improve the anti-submersion performance and improve the safety. The lower the safety detection score, the higher the safety of the vehicle driving, and the requirement for anti-submersion is relatively low. The height of the anti-submersion assembly 82 can be controlled to be lowered to improve the comfort on the premise of ensuring a certain safety. The safety setting score can be pre-set according to experience or test, and different vehicles can be set to different values.

[0098] According to the adjustment of the height of the anti-submersion system 81 of the vehicle according to different driving conditions, the adaptability of the protection degree of the vehicle in different conditions can be realized, the balance between the comfort and the safety of the vehicle can be maintained, and the riding experience can be improved.

[0099] In some embodiments, the vehicle driving condition information includes a wheel speed.

[0100] Figure 3 Fig. 6 shows a flowchart of another exemplary embodiment of the anti-submersion method of the present application. Figure 3 In the embodiment shown, step S11 includes step 21 of acquiring a wheel speed. The wheel speed can be detected by a sensor.

[0101] Step S12 includes step 22 of determining a safety detection score according to the wheel speed. Since the wheel speed and the vehicle driving speed are not consistent when the vehicle is in a slipping, emptying or the like working condition, the vehicle driving speed can be zero, but the wheel is rotating at a high speed. At this time, the safety is low, but if the vehicle driving speed is used for judgment, the safety is determined to be high. Therefore, according to the wheel speed, the running condition of the vehicle can be more accurately judged, and the safety detection score can be more accurately determined.

[0102] In some embodiments, determining the safety detection score according to the wheel speed includes:

[0103] An wheel speed range interval in which the wheel speed is located is determined. A range from a minimum wheel speed to a maximum wheel speed can be divided into a plurality of wheel speed range intervals, which can be pre-configured. The wheel speed range interval in which the current wheel speed belongs is determined.

[0104] A speed score corresponding to the wheel speed range interval is obtained. The plurality of wheel speed range intervals correspond to a plurality of speed scores one-to-one, and the greater the value in the wheel speed range interval, the greater the corresponding speed score. The wheel speed range interval corresponds to a plurality of speed scores one-to-one, which can be stored correspondingly. The greater the value in the wheel speed range interval, the greater the wheel speed, which is relatively less safe, and the greater the corresponding speed score obtained.

[0105] A safety detection score is determined according to the speed score. In this way, the influence of the wheel speed on safety can be considered. The speed score can be quickly determined in this embodiment, so that the safety detection score can be quickly determined, and the anti-submarine component can be controlled in time. In some embodiments, the speed score can be used as the safety detection score. In other embodiments, the speed score can be processed to obtain the safety detection score, such as addition or multiplication with other values.

[0106] Specifically, in some embodiments, the maximum range of the wheel speed is 0-100 km / h, and each 10 km / h is set as a wheel speed range interval. The speed score corresponding to each wheel speed range interval increases by 1, and the higher the speed, the higher the corresponding speed score, until the maximum score of 10 points. In this way, the speed range is divided, and the corresponding speed score is determined.

[0107] In some embodiments, the driving environment information includes dryness-related data representing the dryness of the driving surface.

[0108] Figure 4 Another exemplary embodiment of the anti-submarine method of the present application is shown in the flowchart. In Figure 4 In the embodiment shown, step S11 includes step 31 of obtaining dryness-related data.

[0109] Step S12 includes step 32 of determining a safety detection score according to the dryness-related data. Vehicles are more likely to skid on wet roads, and safety accidents such as brake failure and vehicle rollover are more likely to occur. Therefore, the dryness of the road is an important factor in vehicle safety. Obtaining dryness-related data of the vehicle and determining a safety detection score according to the data can help quantify the abstract dryness of the road and facilitate the determination of whether it is safe to drive on a road with a certain dryness. Different dryness or different dryness ranges can correspond to different safety detection scores.

[0110] In some embodiments, the dryness-related data comprises a rotation speed of the motor of the vehicle. When the road surface is relatively dry, the road surface generates a relatively large resistance to the vehicle, and when the vehicle travels with a large resistance, the rotation speed of the motor of the vehicle increases. Therefore, the rotation speed of the motor of the vehicle can reflect the dryness of the travel road surface.

[0111] In step 31, the dryness-related data is obtained, including obtaining the rotation speed of the motor.

[0112] In step 32, the safety detection score is determined according to the dryness-related data, including determining the safety detection score according to the rotation speed of the motor. The rotation speed of the motor can more accurately reflect the dryness of the travel road surface of the vehicle. Determining the safety detection score according to the obtained rotation speed of the motor is beneficial to quantitatively judge the rotation speed of the motor, and further to realize the specificization of the abstract subjective dryness of the road surface into a numerical value, which is convenient for judging the driving safety of the vehicle.

[0113] In some embodiments, the safety detection score is determined according to the rotation speed of the motor, including:

[0114] The rotation speed range interval in which the rotation speed of the motor is located is determined. The range from the minimum rotation speed of the motor to the maximum rotation speed of the motor can be divided into multiple rotation speed range intervals, which can be pre-set. The rotation speed range interval to which the current rotation speed of the motor belongs is determined.

[0115] The rotation speed score corresponding to the rotation speed range interval is obtained. The multiple rotation speed range intervals correspond to multiple rotation speed scores one by one, and the smaller the value in the rotation speed range interval in the multiple rotation speed range intervals, the larger the corresponding rotation speed score. The rotation speed score is a score representing the safety of the rotation speed. The smaller the value in the rotation speed range interval, the smaller the rotation speed of the motor, the more humid the road surface, and the more unsafe it is, and the larger the corresponding obtained rotation speed score.

[0116] The safety detection score is determined according to the rotation speed score. Matching the rotation speed score with the corresponding safety detection score is beneficial to uniformly judging the safety of the vehicle according to the size of the safety detection score.

[0117] In some embodiments, the dryness-related data comprises a travel road surface image. The travel road surface image can reflect the dryness of the travel road surface of the vehicle.

[0118] In step 31, the dryness-related data is obtained, including obtaining the travel road surface image. The travel road surface image can be obtained by a shooting device.

[0119] In step 32, the safety detection score is determined according to the dryness-related data, including determining the safety detection score according to the travel road surface image. The travel road surface image can more accurately reflect the dryness, and therefore the safety detection score can be accurately determined through the travel road surface image.

[0120] Specifically, the safety detection score is determined according to the driving road surface image, including:

[0121] From the plurality of road surface reference images, a road surface reference image matching the driving road surface image is determined as a road surface matching image. The road surface reference images can be pre-stored, and different road surface reference images represent different road dryness levels. One road surface reference image matching the obtained driving road surface image is selected from the plurality of road surface reference images as a road surface matching image, and the road surface matching image has the same or within a certain dryness level range as the road dryness level represented by the obtained driving road surface image.

[0122] The road dryness score corresponding to the road surface matching image is determined, the plurality of road surface reference images correspond to the plurality of road dryness scores one by one, and the lower the road dryness level represented by the plurality of road surface reference images, the greater the corresponding road dryness score. The lower the road dryness level, the more slippery the road, and the lower the safety of the vehicle driving on the slippery road. The greater the road dryness score corresponding to the relatively wet road, which is convenient for judging the dry and wet conditions of the road. The plurality of road surface reference images and the plurality of road dryness scores correspond one by one, which can be pre-stored and can be set according to experience or test.

[0123] The safety detection score is determined according to the road dryness score. According to the road dryness score, the safety detection score is determined, which is beneficial to compare the road dryness level with other factors affecting the safety of the vehicle, and to determine the safety detection score, which is beneficial to quantitatively judge the road dryness level.

[0124] In some embodiments, the driving environment information includes visibility-related data representing the visibility of the driving environment.

[0125] Figure 5 The flowchart shown is another exemplary embodiment of the submersion prevention method of the present application. In Figure 5 In the embodiment shown, the step S11 of obtaining driving information includes the step 41 of obtaining visibility-related data. The step S12 of determining the safety detection score representing the safety condition of the vehicle according to the driving information includes the step 42 of determining the safety detection score according to the visibility-related data. The visibility of the vehicle during driving is an important factor for evaluating the safety of the vehicle. When the visibility is low, the driver's driving field of view is limited, and more unexpected situations may occur during driving, which increases the probability of sudden braking and the possibility of the passengers sliding forward. By determining the safety detection score according to the visibility-related data, the vehicle can enter the submersion prevention state when the visibility is low, which is beneficial to improve the safety of the vehicle driving. Different visibility or different ranges of visibility can correspond to different safety detection scores.

[0126] In some embodiments, the visibility-related data comprises a wavelength of a radar-received echo reflected by a vehicle surrounding environment. The radar can emit waves to the surrounding environment where the vehicle travels, and the wavelength of the reflected echo is shorter when the visibility is poor, and thus the wavelength of the echo can reflect the visibility of the driving environment.

[0127] The step 41 obtains the visibility-related data, comprising: obtaining the wavelength of the echo; and the step 42 determines the safety detection score according to the visibility-related data, comprising: determining a wavelength range interval where the wavelength of the echo is located. The wavelength range interval where the reflected wave is located can be determined, and a plurality of wavelength range intervals can be pre-set. The maximum wavelength range can be divided into a plurality of wavelength range intervals, and the wavelengths in a wavelength range interval correspond to a smaller visibility difference.

[0128] The wavelength range interval corresponds to a wavelength score, and the plurality of wavelength range intervals correspond to a plurality of wavelength scores one-to-one, and the smaller the value in the wavelength range interval, the larger the corresponding wavelength score. The wavelength range interval corresponds to a plurality of wavelength scores one-to-one, which can be stored correspondingly. The smaller the value in the wavelength range interval, the smaller the visibility of the vehicle driving environment, which is relatively less safe, and the corresponding obtained wavelength score is also larger.

[0129] The safety detection score is determined according to the wavelength score. In this way, the influence of visibility on safety can be considered. The wavelength score can be quickly determined in this embodiment, so that the safety detection score can be quickly determined, and the anti-submarine component can be controlled in time. In some embodiments, the wavelength score can be used as the safety detection score. In other embodiments, the wavelength score can be processed to obtain the safety detection score, such as addition or multiplication with other values.

[0130] In some embodiments, the visibility-related data comprises a driving environment image; and the driving environment image can reflect the visibility of the vehicle driving environment.

[0131] The step 41 obtains the visibility-related data, comprising: obtaining the environment image data of the surrounding environment of the vehicle;

[0132] The step 42 determines the safety detection score according to the visibility-related data, comprising: determining the safety detection score according to the environment image data. The driving environment image can more accurately reflect the visibility, and thus the visibility can be accurately determined through the driving environment image.

[0133] In some embodiments, the safety detection score is determined according to the environment image data, comprising:

[0134] From the plurality of environment reference images, an environment reference image matching the environment image is determined as an environment matching image. The environment reference images can be pre-stored, and different environment reference images represent different environment visibility. One of the plurality of environment reference images matching the acquired environment image is selected as the environment matching image, and the environment matching image has the same or within a certain visibility range of the driving environment visibility represented by the acquired driving environment image.

[0135] A visibility score corresponding to the environment matching image is determined, the plurality of environment reference images correspond to a plurality of visibility scores one by one, and the lower the visibility represented by the plurality of environment reference images, the higher the corresponding visibility score. The lower the visibility of the photographed environment image, the lower the corresponding matching environment reference image, the lower the visibility, the lower the safety factor of the vehicle during driving, so the lower the visibility, the higher the corresponding visibility score. The plurality of environment reference images and the plurality of visibility scores correspond one by one, which can be pre-stored and set according to experience or experiment.

[0136] According to the visibility score, a safety detection score is determined. According to the calculated visibility score, the safety detection score is determined, which is beneficial to calculate and judge the safety condition of vehicle driving together with other vehicle safety factors.

[0137] In some embodiments, the vehicle driving condition information includes wheel speed, the driving environment information includes dryness-related data representing the dryness of the driving surface and visibility-related data representing the visibility of the driving surface.

[0138] Step S11 acquires driving information, including:

[0139] A plurality of driving information data is acquired, and the plurality of driving information data includes at least two of wheel speed, dryness-related data and visibility-related data. Through the plurality of driving information data, it is beneficial to comprehensively and accurately judge the safety condition of vehicle driving.

[0140] According to the driving information, a safety detection score representing the safety condition of the vehicle is determined, including:

[0141] A detection score corresponding to each of the plurality of driving information data is determined. The plurality of driving information data is determined as the corresponding detection score, which is beneficial to unify different detection contents into the same score, and is convenient for directly judging the safety degree of vehicle driving according to the score. Different driving information data can correspond to different detection scores.

[0142] The safety detection score is determined according to the sum or weighted sum of the plurality of detection scores. Since a plurality of factors need to be considered when judging whether the vehicle is safe, and the influence of various factors on the safety of the vehicle driving is different, in some embodiments, the final safety detection score can be determined by adding the plurality of detection scores, or the plurality of detection scores can be weighted and calculated according to the influence of the plurality of driving information data on the vehicle safety index to determine the final safety detection score, which is beneficial to more accurately judge the safety of the vehicle driving.

[0143] In some embodiments, step S12 determines the safety detection score representing the safety of the vehicle according to the driving information, which can be obtained by inputting the obtained driving information into a calculation system trained by a large amount of data in advance to obtain the final safety detection score.

[0144] In some embodiments, the anti-submersion assembly 82 includes a mounting skeleton 86 and a plurality of protrusions 87 arranged on the surface of the mounting skeleton 86. Step S13 controls the anti-submersion assembly 82 to be in a safe state if the safety detection score is not greater than the safety setting score, including: controlling the driving circuit for driving the plurality of protrusions 87 to provide a first driving force.

[0145] Step S14 controls the anti-submersion assembly 82 to be in a submersion-preventing state if the safety detection score is greater than the safety setting score, including: controlling the driving circuit for driving the plurality of protrusions 87 to provide a second driving force.

[0146] In the present application, the first driving force is greater than the second driving force. When the vehicle is in a safe state, the plurality of protrusions 87 on the surface of the mounting skeleton 86 can be driven by the first driving force to massage the passengers, which is beneficial to improve the comfort of the passengers.

[0147] When the safety detection score is greater than the safety setting score, it can be determined that the safety factor of the vehicle driving at this time is low, and the vehicle is prone to sudden braking and other conditions, and the passengers are prone to slip relative to the vehicle to cause damage. At this time, the height of the anti-submersion assembly 82 is relatively high, so the driving circuit is controlled to control the plurality of protrusions 87 with a second driving force smaller than the first driving force, so that the protrusions 87 act on the human body with a smaller force, avoiding the discomfort brought to the human body due to the large force acting on the human body after the height of the anti-submersion assembly 82 rises.

It is intended that the specification and examples be considered as exemplary only, with the true scope and spirit of the application being indicated by the following claims.

[0149] It is to be understood that the application is not limited to the precise construction already described above and shown in the drawings, and that various modifications and changes can be made by those skilled in the art without departing from the scope of the application. The scope of the application should only be limited by the claims appended hereto.
