Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to a control method, system, and vehicle for a vehicle experiencing weightlessness. Background Technology

[0002] As people's living standards continue to improve, cars, as a means of transportation, have become a necessity for countless households. After the power performance of cars met people's needs, people began to pay increasing attention to the safety performance of vehicles.

[0003] Currently, most cars do not take any action after a dangerous accident. A few cars are equipped with emergency roadside assistance services. When the vehicle receives an accident signal, its computer sends the information to a service platform. The platform first contacts the driver to confirm the situation and then calls the police based on the actual circumstances. This approach is sufficient for less urgent traffic accidents. However, due to its inherent delay, this method can easily lead to dangerous situations in particularly urgent accidents.

[0004] In particularly urgent traffic accidents, including those involving cars falling into water or plunging into the road, occupants are likely to become tense and panicked, making it difficult or impossible for them to open windows. In such situations, failing to open windows and sunroofs promptly can significantly delay escape time for those inside the vehicle.

[0005] Existing technologies also provide methods for automatically opening car windows when a car is submerged in water. However, these solutions use gravity sensors installed under the seats to detect whether anyone is inside the vehicle and thus determine whether to open the window. But if there are other heavy objects on the seats, it can also cause the window to open. In the event of a car fall, unnecessary window opening increases the risk of occupants being ejected from the vehicle.

[0006] Therefore, it is essential to provide a control method, system, and vehicle for vehicles experiencing weightlessness to address the aforementioned technical problems. Summary of the Invention

[0007] This invention provides a control method for vehicles in the event of weightlessness. It solves the problem in related technologies where only gravity sensors are used to detect whether there are people inside the vehicle, and then windows are opened in a weightless state. This is because such windows are easily affected by other heavy objects, and if unnecessary window opening is performed, the risk of people inside the vehicle being thrown out of the vehicle increases.

[0008] On the one hand, embodiments of the present invention provide a control method for a vehicle after it experiences weightlessness.

[0009] It includes the following steps:

[0010] When the vehicle speed exceeds the preset speed threshold:

[0011] If all occupants are wearing seatbelts, open the windows on the side where each occupant is located.

[0012] When there are people in the vehicle who are not wearing seat belts

[0013] If you are in the front row, close the window on that side and open the window on the other side.

[0014] If you are in the back seat, close all the rear windows.

[0015] When the vehicle speed is less than a preset speed threshold and the duration of the maintenance exceeds a preset duration threshold:

[0016] Open all the car windows.

[0017] Furthermore, when the vehicle speed exceeds a preset speed threshold and all occupants are wearing seat belts, the sunroof will be opened if it is not open.

[0018] Furthermore, if the vehicle speed exceeds a preset speed threshold and there are unbelted passengers in the vehicle, the sunroof will be closed if it is already open.

[0019] Furthermore, if the vehicle speed is less than a preset speed threshold and the duration of the hold is greater than a preset duration threshold, the sunroof will be opened if it is not open.

[0020] Furthermore, the control method also includes a step of identifying whether occupants are wearing seat belts, which specifically includes:

[0021] Take photos of the people inside the vehicle;

[0022] Recognize the captured photos;

[0023] If a diagonally fastened seatbelt is identified in the photo, then the occupants of the vehicle are wearing seatbelts.

[0024] Otherwise, the occupants of the vehicle are not wearing seat belts.

[0025] Furthermore,

[0026] The term "vehicle weightlessness" refers to one or more of the following: vehicle falling into water, vehicle wading through deep water, and vehicle falling and rolling.

[0027] Furthermore, the steps for identifying "vehicle weightlessness" include:

[0028] Determine whether the Z-axis acceleration jump of the three-axis acceleration sensor inside the vehicle stability system exceeds the preset acceleration threshold;

[0029] If the acceleration does not exceed the preset threshold, it is determined that the vehicle is not experiencing weightlessness.

[0030] If the acceleration exceeds a preset threshold, then the duration is determined to exceed a preset threshold.

[0031] If the duration exceeds the preset threshold, it is determined that there is no weightlessness;

[0032] If the duration does not exceed the preset threshold, it is judged as weightlessness.

[0033] On the one hand, a control system for a vehicle after weightlessness is provided, including:

[0034] The first module is used when the vehicle speed exceeds a preset speed threshold:

[0035] If all occupants are wearing seatbelts, open the windows on the side where each occupant is located.

[0036] When there are people in the vehicle who are not wearing seat belts

[0037] If you are in the front row, close the window on that side and open the window on the other side.

[0038] If you are in the back seat, close all the rear windows.

[0039] When the vehicle speed is less than a preset speed threshold and the duration of the maintenance exceeds a preset duration threshold:

[0040] Open all the car windows.

[0041] Furthermore, it also includes:

[0042] The second module is used to determine whether the Z-axis acceleration jump of the triaxial acceleration sensor inside the vehicle stability system exceeds the preset acceleration threshold.

[0043] If the acceleration does not exceed the preset threshold, it is determined that the vehicle is not experiencing weightlessness.

[0044] If the acceleration exceeds a preset threshold, then the duration is determined to exceed a preset threshold.

[0045] If the duration exceeds the preset threshold, it is determined that there is no weightlessness;

[0046] If the duration does not exceed the preset threshold, it is judged as weightlessness.

[0047] On the one hand, a vehicle is provided, including a control system for vehicle weightlessness as described in any of the above claims.

[0048] The beneficial effects of the technical solution provided by this invention include:

[0049] By monitoring passenger and seatbelt usage information in various locations within the vehicle, the system ensures that the sunroof and windows on the same side as the unbelted passenger are not opened when someone is not wearing a seatbelt, thus reducing the risk of unbelted passengers being ejected from the vehicle. Opening the windows on the same side and the sunroof when all passengers are wearing seatbelts effectively increases their escape time. Attached Figure Description

[0050] To more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0051] Figure 1 This is a flowchart of a control method for a vehicle after weightlessness according to the present invention. Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] See Figure 1 As shown, this embodiment of the invention provides a control method for a vehicle after it experiences weightlessness.

[0054] It includes the following steps:

[0055] S100. When the vehicle speed exceeds the preset vehicle speed threshold:

[0056] S110. When all occupants are wearing seat belts, open the windows on the side where each occupant is located;

[0057] S120. Determine whether all passengers in the vehicle are wearing seat belts;

[0058] S121. If not:

[0059] S122. If it is a front seat, close the window on that side and open the window on the other side;

[0060] S123. If it is a rear seat, close all rear windows;

[0061] S130. If so:

[0062] S131. Open the windows on the sides where each passenger is located;

[0063] S140. When the vehicle speed is less than the preset vehicle speed threshold and the duration of the hold is greater than the preset hold threshold:

[0064] S141. Open all windows.

[0065] In this embodiment, existing technology uses gravity sensors installed under the seats to detect whether there are people inside the vehicle, thereby determining whether to open the window. If there are other heavy objects on the seat, it will also cause the window to open. In the event of a car crash, unnecessary window opening increases the risk of occupants being ejected from the vehicle. To overcome these technical problems, this embodiment rationally detects occupant information and seatbelt usage information at various locations, and can make reasonable judgments based on a preset speed threshold. When the vehicle speed is greater than the preset threshold, ensuring that someone inside the vehicle is not wearing a seatbelt, if it is a front-seat occupant, the window on the same side as the unbelted occupant is closed, and the window on the other side is opened; if it is a rear-seat occupant not wearing a seatbelt, all rear windows are closed. When the vehicle speed is less than the preset speed threshold, all windows are opened.

[0066] When a car is falling, its speed typically decreases from high to low. When the car is moving at a high speed, avoiding unnecessary window opening reduces the risk of occupants being ejected from the vehicle. Once the car's speed decreases, all windows are opened for escape.

[0067] Additionally, there are situations where the vehicle's falling speed is not high. In this case, there's no need to worry about the risk of occupants being ejected from the vehicle due to unnecessary window opening during a fall. In such cases, opening all windows can effectively increase the escape time for those inside. This also includes the automatic opening of the sunroof when the vehicle's speed is low. It's important to note whether the vehicle has overturned. By installing gravity sensors in the vehicle, it's possible to detect this effectively. If the vehicle has overturned and is upside down, the sunroof will not open.

[0068] Secondly, there are situations where, for example, during a vehicle's weightless fall, the speed suddenly drops below the preset speed threshold, but only for a short period. In such cases, it's necessary to use both the preset speed threshold and the preset duration threshold for judgment. When the vehicle speed is below the preset speed threshold and the duration is greater than the preset duration threshold, all windows should be opened.

[0069] Meanwhile, the vehicle speed preset threshold and the maintenance preset threshold can be appropriately adjusted by the car manufacturer or relevant personnel according to the actual situation, and these are all within the scope of protection of this application.

[0070] In some embodiments, when the vehicle speed is greater than a preset speed threshold and all occupants are wearing seat belts, the sunroof will be opened if it is not open.

[0071] In this embodiment, after confirming vehicle weightlessness, photos are taken of various locations inside the vehicle, and facial recognition is performed on the photos to identify and determine the seating situation of people in each location. Simultaneously, photos of people in corresponding locations are taken to determine if they are wearing seatbelts. This effectively avoids the problem of existing technologies that use gravity sensors installed under the seats to detect the presence of people inside the vehicle and determine whether to open windows. However, if there are other heavy objects on the seats, it may also lead to window opening. In the event of a car crash, unnecessary window opening increases the risk of occupants being ejected from the vehicle. Facial recognition, on the other hand, can more accurately determine the information of people in corresponding locations inside the vehicle, avoiding the potential problem of unnecessary window opening in the event of a car crash.

[0072] Secondly, because the sunroof is located in the middle of the roof, if the vehicle rolls over, occupants in any position inside could be thrown out through the sunroof. If the vehicle's speed exceeds a preset threshold and any occupants are not wearing seatbelts, they are highly likely to be ejected from the vehicle.

[0073] In addition, under normal circumstances, a car sunroof may be open or closed. If the vehicle speed exceeds a preset speed threshold, the system should immediately determine whether the sunroof is open or closed, and whether the occupants are wearing seat belts. If the sunroof is closed, it should be kept closed.

[0074] In some embodiments, when the vehicle speed exceeds a preset threshold and there are unbelted passengers in the vehicle, the sunroof will be closed if it is already open.

[0075] In this embodiment, after confirming vehicle weightlessness, photos are taken of various locations inside the vehicle, and facial recognition is performed on the photos to identify and determine the seating situation of people in each location. Simultaneously, photos of people in corresponding locations are taken to determine if they are wearing seatbelts. This effectively avoids the problem of existing technologies that use gravity sensors installed under the seats to detect the presence of people inside the vehicle and determine whether to open windows. However, if there are other heavy objects on the seats, it may also lead to window opening. In the event of a car crash, unnecessary window opening increases the risk of occupants being ejected from the vehicle. Facial recognition, on the other hand, can more accurately determine the information of people in corresponding locations inside the vehicle, avoiding the potential problem of unnecessary window opening in the event of a car crash.

[0076] Secondly, because the sunroof is located in the middle of the roof, if the vehicle rolls over, occupants in any position inside could be thrown out through the sunroof. If the vehicle's speed exceeds a preset threshold and any occupants are not wearing seatbelts, they are highly likely to be ejected from the vehicle.

[0077] In addition, under normal circumstances, a car sunroof may be open or closed. If the vehicle speed exceeds a preset speed threshold, the system will immediately determine whether the sunroof is open or closed, and whether the occupants are wearing seat belts. If no occupants are wearing seat belts, the system will close the sunroof if it is open.

[0078] In some embodiments, if the sunroof is not open when the vehicle speed is less than a preset threshold and the duration is greater than a preset threshold, the sunroof will be opened.

[0079] In this embodiment, when a car falls, its speed typically decreases from high to low. That is, when the car is moving at a high speed, unnecessary window opening is avoided to reduce the risk of occupants being thrown out of the vehicle. Once the car's speed decreases, all windows are opened to allow occupants to escape.

[0080] In addition, under normal circumstances, a car's sunroof may be open or closed. If the vehicle speed is less than a preset speed threshold, the step of checking whether the occupants are wearing seat belts is skipped. If the sunroof is open, it will remain open; if the sunroof is not open, it will be opened.

[0081] In some embodiments, the control method further includes a step of identifying whether occupants are wearing seat belts, which specifically includes:

[0082] S150. Take photos of the people inside the vehicle;

[0083] S151. Recognize the captured photos;

[0084] S152. If a diagonally pulled seatbelt is identified in the photograph, then the occupants of the vehicle are wearing seatbelts;

[0085] S153. Otherwise, the occupants of the vehicle are not wearing seat belts.

[0086] In this embodiment, the car's own computer has a built-in device for detecting seatbelt use and non-use. However, in real life, it is difficult to avoid occupants using seatbelt buckles, which can interfere with the car's built-in seatbelt use detection. Therefore, this application directly photographs the occupants and identifies the images. When a diagonally pulled seatbelt is detected, it indicates that the occupant is properly fastened; if no diagonally pulled seatbelt is detected, it indicates that the occupant is not properly fastened. Image recognition accurately determines seatbelt use, preventing the system from misjudging an unfastened occupant as fastened and opening the window on that side, which could result in the unfastened occupant being ejected from the vehicle during a fall.

[0087] In some embodiments,

[0088] The term "vehicle weightlessness" refers to one or more of the following: vehicle falling into water, vehicle wading through deep water, and vehicle falling and rolling.

[0089] In this embodiment, "vehicle weightlessness" is not limited to situations where the vehicle falls into the water, but also includes situations where the vehicle is submerged in water or deeply submerged. In these cases, if the vehicle windows are closed, it could significantly delay the escape time for occupants. When a vehicle falls into water, occupants may panic and be unable to open the windows. Furthermore, if the electronic locks are not opened immediately after the vehicle falls into water, they can easily malfunction as the vehicle floods. If the car has manual windows, occupants can escape by manually rolling them down. However, if the windows are electric, they may short-circuit due to water ingress, preventing them from opening. When windows cannot be opened, the only escape method is to open the doors. However, this requires waiting for the pressure inside and outside the car to equalize. If the pressure is unequal, forcibly opening the doors will reduce the chance of escape. Therefore, the best escape opportunity is to open the windows promptly after the vehicle falls into water.

[0090] In some embodiments, the "vehicle weightlessness" identification step includes:

[0091] S160. Determine whether the Z-axis acceleration jump of the three-axis acceleration sensor inside the vehicle stability system exceeds the preset acceleration threshold;

[0092] S161. If the acceleration preset threshold is not exceeded, it is determined that the vehicle is not weightless;

[0093] S162. If the acceleration exceeds the preset threshold, then determine that the duration exceeds the preset threshold.

[0094] S163. If the duration exceeds the preset threshold, it is determined that there is no weightlessness;

[0095] S164. If the duration does not exceed the preset threshold, it is determined to be weightlessness.

[0096] In this embodiment, road surface unevenness causes corresponding vibrations in the vehicle. Therefore, acceleration sensors are installed on the front and rear axles to obtain the vertical acceleration of the axles during vehicle movement. Since the vertical vibrations of the front and rear suspension systems are almost independent, two independent vibration systems are obtained. When the vehicle experiences weightlessness, the Z-axis acceleration of the acceleration sensors installed on the front and rear axles jumps and exceeds a preset acceleration threshold. Furthermore, during actual driving, the Z-axis acceleration of the acceleration sensors installed on the front and rear axles may also jump when the vehicle speed is too high or encounters an incline. Therefore, a preset duration threshold is set. That is, if the Z-axis acceleration jumps and the duration exceeds the preset duration threshold, it is considered weightlessness. If the acceleration exceeds the preset threshold but the duration does not exceed the preset threshold, it is considered transient weightlessness.

[0097] On the one hand, a control system for a vehicle after weightlessness is provided, including:

[0098] The first module is used when the vehicle speed exceeds a preset speed threshold:

[0099] If all occupants are wearing seatbelts, open the windows on the side where each occupant is located.

[0100] When there are people in the vehicle who are not wearing seat belts

[0101] If you are in the front row, close the window on that side and open the window on the other side.

[0102] If you are in the back seat, close all the rear windows.

[0103] When the vehicle speed is less than a preset speed threshold and the duration of the maintenance exceeds a preset duration threshold:

[0104] Open all the car windows.

[0105] In some embodiments, it also includes:

[0106] The second module is used to determine whether the Z-axis acceleration jump of the triaxial acceleration sensor inside the vehicle stability system exceeds the preset acceleration threshold.

[0107] If the acceleration does not exceed the preset threshold, it is determined that the vehicle is not experiencing weightlessness.

[0108] If the acceleration exceeds a preset threshold, then the duration is determined to exceed a preset threshold.

[0109] If the duration exceeds the preset threshold, it is determined that there is no weightlessness;

[0110] If the duration does not exceed the preset threshold, it is judged as weightlessness.

[0111] On the one hand, a vehicle is provided, including a control system for vehicle weightlessness as described in any of the above claims.

[0112] The beneficial effects of this invention are as follows:

[0113] By monitoring passenger and seatbelt usage information in various locations within the vehicle, the system ensures that the sunroof and windows on the same side as the unbelted passenger are not opened when someone is not wearing a seatbelt, thus reducing the risk of unbelted passengers being ejected from the vehicle. Opening the windows on the same side and the sunroof when all passengers are wearing seatbelts effectively increases their escape time.
