Description

Technical Field

[0001] The present invention relates to the field of vehicle safety technology, and more specifically, to an emergency escape control system, method and vehicle based on sudden accidents. Background Art

[0002] As the number of vehicles in China continues to increase, the traffic volume during rush hour on weekdays is also increasing, and the safety hazards of vehicle driving are also increasing, leading to the current situation of frequent traffic accidents.

[0003] One of the types of traffic accidents that currently exist is: when a vehicle is rear-ended continuously or when a vehicle is sandwiched by two or more vehicles colliding head-on, the accident vehicle is severely hit both in the front and rear, and the space inside the vehicle is sharply compressed in a short period of time. Traditional airbags can no longer effectively protect the casualties caused by the sudden compression of the space inside the vehicle. The passive safety devices and systems currently available in the market for vehicles involved in traffic accidents mainly include: automatic emergency braking system (AEB), airbags, seat belt pretensioning system, automatic collision warning system, emergency avoidance system, etc., but these systems have the following main disadvantages:

[0004] (1) Automatic emergency braking system, which is an integrated system of active safety technologies that uses active braking to mitigate or avoid collisions when the vehicle is in an emergency condition. Although this system can avoid possible vehicle collisions to the greatest extent possible, it can only control the vehicle body to perform emergency braking and cannot effectively avoid collisions with other vehicles. In addition, in the case of a vehicle being sandwiched or rear-ended continuously, emergency braking can only be used to stop the vehicle body from moving, which cannot effectively avoid collision accidents.

[0005] (2) Airbags. Although airbags can minimize the impact damage caused by a vehicle to the occupants when a collision occurs, when the vehicle is sandwiched or rear-ended repeatedly, the space inside the vehicle is compressed in a short period of time. Airbags alone cannot effectively reduce the impact damage caused by the vehicle to the occupants, and therefore cannot effectively protect the lives of the occupants.

[0006] (3) Seat belt pretensioning system. Although the seat belt pretensioning system can firmly fix the occupants in the seats in the event of a vehicle collision to reduce the accidental injuries caused by the separation of the occupants from the seats in the event of a vehicle collision, it still cannot provide effective survival space for the occupants in the event of a vehicle being clamped or rear-ended repeatedly;

[0007] (4) Automatic collision warning system, which can only provide medical assistance to unconscious occupants after a collision, but cannot be effective when a vehicle collision occurs;

[0008] (5) Emergency avoidance system: This system can actively intervene in driving when a vehicle is about to collide, assisting the vehicle to temporarily avoid to the adjacent lane, greatly reducing the probability of a collision. However, if the vehicle is sandwiched or rear-ended repeatedly and the adjacent lane is occupied by other vehicles, it cannot make effective avoidance and cannot effectively prevent a collision accident.

[0009] In summary, based on the shortcomings of the above-mentioned passive safety devices and systems, there is an urgent need for an emergency escape system that can effectively protect the safety of occupants in the event of a sudden accident caused by a series of rear-end collisions or a vehicle being simultaneously sandwiched by two or more vehicles colliding in opposite directions.

[0038] Further features and advantages of the present invention will become apparent from the following detailed description of exemplary embodiments of the present invention with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0046] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0047] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0048] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0049] In the existing environment, when a vehicle is rear-ended continuously or is sandwiched by two or more vehicles colliding head-on, the accident vehicle is severely hit both in the front and rear, and the space inside the vehicle is sharply compressed in a short period of time. Traditional airbags can no longer effectively protect the casualties caused by the sharp compression of the space inside the vehicle, and other existing passive safety technologies, such as AEB, ABS, etc., cannot guarantee the life safety of the occupants in the vehicle when such traffic accidents occur. In the event of a collision, this application opens the sunroof, adjusts the front seats to the rear position, adjusts the rear seats to the front position and adjusts the seats upward to the highest position at the same time, and raises the suspension to the maximum height, so that all the occupants in the vehicle are concentrated in the upper middle part of the vehicle where the collision deformation is small, close to the sunroof. This provides the possibility for the survival of the occupants in the vehicle and improves the survival rate of the occupants in the vehicle.

[0050] This application is based on the following simulation analysis to draw conclusions: when a vehicle is rear-ended continuously or is sandwiched by two or more vehicles colliding with each other, the area with smaller collision deformation is located in the upper middle part of the vehicle near the sunroof. The specific simulation analysis process is as follows:

[0051] First, based on the traffic accident types of vehicles that are rear-ended continuously or are sandwiched by two or more vehicles colliding with each other at the same time, the following assumptions are made when the vehicle is sandwiched or rear-ended continuously:

[0052] 1. The trapped vehicle was an SUV, 4.5 meters long and with a wheelbase of 2.7 meters;

[0053] 2. When the SUV is sandwiched from front and back, the SUV and the vehicle in front are driving at a normal low speed or stationary, and their speed is much lower than the speed of the out-of-control vehicle behind. To simplify the analysis, it is assumed that the SUV and the vehicle in front are stationary;

[0054] 3. Since the collision occurs instantly and in a very short time, the impact of wind resistance, weather and other factors on the vehicle is not considered. This type of accident is simplified to a static structural model analysis;

[0055] 4. The instantaneous speed of the out-of-control vehicle when it hit the SUV was 80 km / h;

[0056] 5. The gross mass of the SUV at the time of the accident was 1500kg.

[0057] Based on the assumptions, a simplified vehicle physical model is made and a modal analysis is performed on it. The modal analysis results are as follows: Figures 2 to 4 shown.

[0058] The modal analysis results are analyzed as follows:

[0059] 1. When a vehicle is hit from the front and back and collides, the front and rear parts of the vehicle are first subjected to greater stress and strain, which in turn causes greater overall deformation of the front and rear parts of the vehicle. This is also the fundamental reason why the space inside the vehicle is compressed for a short time when a collision occurs;

[0060] 2. According to the stress analysis results of modal analysis, it can be obtained that at the upper end of the middle part of the vehicle near the sunroof, after the vehicle collides, the impact energy generated by the collision is significantly weakened after being buffered by the head and tail of the vehicle, so that the stress, strain and overall deformation at the upper end of the middle part of the vehicle near the sunroof are relatively small;

[0061] 3. Analyzing from the overall structural design of the vehicle body, the vehicle's head and tail are equipped with in-vehicle electrical appliances and various power devices, which can also absorb the energy generated by the collision when a collision occurs, and further reduce the deformation of the vehicle's central space; at the same time, the vehicle's central space is larger than the vehicle's front and rear spaces. When the deformation of the central space is small, the upper central space of the vehicle is more likely to provide survival space for the occupants in the event of a collision.

[0062] From the above analysis, it can be concluded that when a vehicle is involved in a sudden accident such as being trapped or rear-ended, the survival rate of the occupants in the vehicle will be greatly improved if they are concentrated in the upper middle part of the vehicle near the sunroof.

[0063] Based on the results of the above simulation analysis, an embodiment of an emergency escape control system based on sudden accidents is proposed. Specifically, Figure 1 shown, including:

[0064] Collision sensing module: includes at least two collision sensors, which are respectively arranged at the front and rear of the vehicle, and are used to sense and generate collision signals when the vehicle encounters a sudden collision accident; wherein the collision sensor adopts an acceleration sensor or a pressure sensor, which can sensitively detect the sudden change of vehicle acceleration or the impact force exerted on the vehicle body, thereby generating a corresponding collision signal.

[0065] Vehicle Information Processing Unit (VIU): used to receive collision signals from the collision sensing module, and process and analyze the collision signals to confirm the severity of the collision event; VIU uses corresponding data processing algorithms and data processing technologies to filter, amplify and extract features of the collision signals.

[0066] Execution control module: includes an input port and an output port. The execution control module is connected to the VIU through the input port and is respectively connected to the sunroof controller, seat controller and suspension controller through the output port. The execution control module sends displacement control instructions to the sunroof controller, seat controller and suspension controller according to the severity of the collision event analyzed by the VIU. When the severity of the collision event reaches a preset accident level, the execution control module sends a displacement control instruction to the sunroof controller, seat controller and suspension controller.

[0067] It should be noted that by quickly sensing a collision and automatically adjusting the vehicle's internal layout, the system can significantly shorten the passengers' escape time and increase their chances of success. When a collision occurs, the system can automatically adjust the seats and suspension to reduce the impact and damage to the passengers, while providing additional escape routes to further ensure passenger safety.

[0068] In an embodiment of the present invention, a sunroof controller is connected to a sunroof adjustment system, which includes a sunroof motor and a sunroof connected to the sunroof motor. The sunroof motor responds to a displacement control instruction from the sunroof controller to automatically open the sunroof when a collision occurs. When a collision occurs, automatically opening the sunroof can provide a faster escape route for the occupants, especially when the vehicle door cannot be opened due to deformation.

[0069] The seat controller is connected to the seat adjustment system, which includes the front seat adjustment motor and the rear seat adjustment motor. The seat adjustment system drives the front seat adjustment motor and the rear seat adjustment motor to adjust the front seat backward to the first preset position (i.e., to the rear position) according to the displacement control command output by the seat controller to reduce the impact of the front seat occupants in the collision, and adjust the rear seat forward to the second preset position (i.e., to the front position) to ensure the safety of the rear seat occupants in the collision, and adjust both the front seat and the rear seat upward to the third preset position (i.e., the highest position) to reduce the risk of collision between the occupants' heads and the roof or other parts in the car. By accurately adjusting the seat position, the impact and injury to the occupants in the collision can be minimized.

[0070] The suspension controller is connected to a suspension adjustment system, which includes an air pump and a suspension lifting mechanism. The air pump is used to provide the required air pressure for the suspension system, while the suspension lifting mechanism is responsible for adjusting the height of the suspension according to instructions. The suspension adjustment system lifts the vehicle suspension to a preset working height (i.e., to the maximum height) through the suspension lifting mechanism and the air pump according to the displacement control instructions of the suspension controller.

[0071] In an embodiment of the present invention, the emergency escape control system based on sudden accidents further includes an auxiliary sensing module, and the auxiliary sensing module includes:

[0072] At least one height sensor: The height sensor is mounted on the suspension of the vehicle and is used to monitor the height change of the vehicle relative to the ground and transmit the height change data to the VIU;

[0073] At least one position pressure sensor is installed on the seat cushion, and is used to monitor the position of the seat, including the front and rear, up and down position and tilt angle of the seat, as well as the distribution and weight of the occupants on the seat, and transmit the monitored data to the VIU; it should be noted that when the position pressure sensor detects that there are no passengers on the front / rear seats, then when a front / rear pinch collision accident occurs, the corresponding front / rear seats will not be displaced, and only the seats with passengers will be quickly displaced, which can improve the accuracy and efficiency of fault protection.

[0074] At least one position sensor is installed at the end of the sunroof track, and is used to detect the current position of the sunroof and transmit the detected data to the VIU.

[0075] In the embodiment of the present invention, the VIU comprehensively evaluates the current state of the vehicle and the safety needs of the occupants based on the collision signal of the collision sensing module and the detection data output by the auxiliary sensing module, and then sends displacement control instructions to the sunroof controller, seat controller and suspension controller respectively. The system achieves accurate perception and rapid response to the vehicle state and occupant needs through a highly integrated sensor network and intelligent decision-making algorithm.

[0076] In addition, CAN and LIN protocols are used to achieve communication and data exchange between various sensors, sunroof controllers, seat controllers and suspension controllers, and various motors.

[0077] In an embodiment of the present invention, the collision sensing module further includes a signal filtering and enhancement circuit, which is used to perform signal filtering and signal enhancement on the collision signal obtained by the collision sensing module. The signal filtering and enhancement circuit includes a signal filtering circuit and a signal enhancement circuit, the signal filtering circuit includes any one of a low-pass filter, a high-pass filter, a band-pass filter, etc., and the signal enhancement circuit includes any one of an operational amplifier, a differential amplifier, etc. Through signal filtering and enhancement, the collision sensing module can more accurately identify collision events, reduce false alarms and missed alarms, and avoid unnecessary activation of protection mechanisms, thereby reducing wear and consumption of other components of the system and extending the overall life of the system.

[0078] In an embodiment of the present invention, the suspension adjustment system further includes a pressure sensor, which is used to monitor the pressure in the suspension airbag in real time, so that the pressure in the suspension airbag is stabilized within a preset pressure range during the process of lifting the suspension to a set height. When the suspension system receives a lifting command, the suspension airbag begins to inflate. During this process, the pressure sensor continuously monitors the pressure change in the airbag. If the pressure exceeds the preset upper limit of the safety range, the airbag may be over-expanded or even ruptured; if the pressure is too low, it may not provide sufficient support, affecting the lifting effect of the suspension and the stability of the vehicle. The preset pressure range is comprehensively determined based on factors such as the specific design, weight distribution, and expected driving conditions of the vehicle. Through real-time monitoring and feedback of the pressure sensor, the suspension control system can accurately adjust the inflation and deflation rate of the airbag so that the pressure is always maintained within the preset range. By accurately controlling the pressure in the suspension airbag, the suspension system can maintain the set height more stably, avoid damage to the suspension airbag due to abnormal pressure, and reduce the risk of traffic accidents caused by suspension failure.

[0079] In an embodiment of the present invention, the emergency escape control system based on sudden accidents also includes a user-defined setting module, through which the user can adjust the first preset position, the second preset position and the third preset position to which the seat is moved, and the preset working height to which the vehicle suspension is raised, according to actual needs. Different passengers have different physical conditions, escape habits and preferences. The user-defined setting module allows passengers to make adjustments according to their own characteristics, so that the emergency escape control system is more in line with personal needs.

[0080] In an embodiment of the present invention, the emergency escape control system based on sudden accidents also includes a user interface indication module, which is connected to the collision sensing module. The user interface indication module includes at least one visual indicator and / or auditory indicator, which is used to provide escape guidance and status feedback to passengers. The escape guidance includes but is not limited to indicating the location of the safety exit and the escape path, and the status feedback includes but is not limited to displaying the execution status of the current safety protection measures, the vehicle power status, and the emergency communication connection status. Through intuitive and easy-to-understand visual and auditory indications, the user interface indication module can quickly guide passengers to find the safety exit and take correct escape actions, thereby significantly improving escape efficiency and reducing casualties.

[0081] The present invention also provides an embodiment of an emergency escape control method based on an unexpected accident, such as Figure 5 As shown, the specific steps include:

[0082] Step 1: Detect collision signals when the front and rear of the vehicle are hit;

[0083] Step 2: receiving a collision signal from a collision sensing module, and processing and analyzing the collision signal to confirm the severity of the collision event;

[0084] Step 3: According to the severity of the collision event analyzed by the VIU, when the severity of the collision event reaches a preset accident level, a displacement control instruction is sent to the sunroof controller, the seat controller, and the suspension controller;

[0085] Step 4: In response to the displacement control command, the sunroof is opened through the sunroof adjustment system, the seat position is adjusted through the seat adjustment system, and the suspension is raised through the suspension adjustment system to focus and protect the occupants in the vehicle.
