Description

Technical Field

[0001] The present invention relates to the technical field of vehicle safety, and in particular to a vehicle rescue and escape system. Background Art

[0002] With the development of new energy vehicles, in order to improve comfort, vehicles are equipped with self-priming locks, hidden door handles, etc. When the self-priming locks and hidden door handles are locked, it is difficult for outsiders to quickly open the doors. However, the batteries of new energy vehicles spontaneously combust very quickly, and the escape time is very short. The rescue escape system is required to respond quickly to open the vehicle doors and windows. The existing vehicle escape systems usually cannot meet the rescue needs of new energy vehicles.

[0003] The Chinese patent with the announcement number CN 109854121 A discloses a car escape system, which sends a distress signal to a remote server through a user terminal. The remote server controls the signal detector to detect whether the car is flooded and stalled and drives the window lifter to drive the window glass to fall down. However, the escape system requires the occupant to trigger the distress signal. When the occupant is in a coma, the escape system cannot be activated, and the window can only be lowered, and the self-priming lock cannot be quickly unlocked, and the hidden door handle cannot be popped out. External rescue personnel cannot help the occupants in the car escape quickly.

[0004] The Chinese patent with the announcement number CN 117601792 A also discloses a vehicle escape system, which obtains the current collision strength data of the car according to the collision strength sensor, so that the adjustment module activates the roof detonator to help the passengers trapped in the car escape and rescue. However, when the car is damaged and the vehicle cannot be powered normally or spontaneous combustion occurs, the escape system cannot work properly, and the destructive force is large, which is easy to accidentally injure the passengers and has low safety.

[0005] Therefore, how to effectively improve the reliability and safety of the vehicle rescue and escape system, quickly respond to open doors and windows in various emergency situations, ensure that occupants in the vehicle can escape safely and quickly, and rescue personnel outside the vehicle can quickly rescue has become an urgent problem to be solved in this field. Summary of the invention

[0006] In view of the defects of the prior art, the object of the present invention is to provide a vehicle rescue and escape system and method that can quickly respond to opening doors and windows in various emergency situations and is safe and reliable.

[0007] In order to achieve the above object, the vehicle rescue escape system provided by the present invention comprises:

[0008] A trigger signal input unit, the trigger signal input unit includes a detection component and an emergency escape switch arranged in the vehicle, and is configured to detect the vehicle's motion state, collision intensity, and the power supply state and spontaneous combustion state of the vehicle's power supply in real time, and can also obtain the on / off state of the emergency escape switch to generate a trigger signal,

[0009] An execution unit, wherein the execution unit is configured to control the locking state of the vehicle's self-priming lock, the pop-up state of the hidden door handle, and the opening state of the vehicle door and window,

[0011] A central control unit is connected to the trigger signal input unit, the execution unit and the backup power supply unit, and is configured to collect and analyze the trigger signal of the trigger signal input unit to control the working status of the execution unit and the backup power supply unit.

[0012] Furthermore, the central control unit is configured with a vehicle body safety state, a first-level emergency state and a second-level emergency state. The central control unit can determine the currently collected trigger signal as a vehicle body safety state, a first-level emergency state or a second-level emergency state to correspond to the working state of the control execution unit.

[0013] Furthermore, the detection component includes a battery management system, an inertial measurement sensor and a collision sensor, and there are at least two emergency escape switches which are arranged at the same or different positions in the vehicle.

[0014] Furthermore, the execution unit includes a self-priming lock controller, a hidden door handle controller, a window breaking controller, a door drive controller, and an external rescue controller arranged outside the vehicle for opening the door.

[0015] Furthermore, the door drive controller includes an electric door controller and an electric spring door controller.

[0016] Furthermore, the external rescue controller includes an illumination prompt light and a door opening button.

[0017] In order to achieve the above object, the vehicle rescue escape method provided by the present invention is based on the vehicle rescue escape system, and the rescue escape method comprises:

[0018] When the central control unit collects and analyzes the trigger signal of the trigger signal input unit and determines that the power supply status of the vehicle power supply is abnormal, it controls the backup power supply unit to work.

[0019] When the central control unit collects and analyzes the trigger signal of the trigger signal input unit and determines that the vehicle is in a safe state, no execution is performed. If the vehicle is determined to be in a level one emergency state, the control execution unit starts the self-priming lock controller and the hidden door handle controller. If the vehicle is determined to be in a level two emergency state, the control execution unit starts the self-priming lock controller, the hidden door handle controller and the external rescue controller, and at the same time determines the working state of the self-priming lock controller to start the door drive controller and / or the window breaking controller.

[0020] Furthermore, the vehicle body safety state is defined as the inertial measurement sensor detecting that the vehicle body is in a non-rollover process, the vehicle speed is lower than the safety speed threshold, and the battery management system detects that the vehicle power supply is in a non-spontaneous combustion state.

[0021] Furthermore, the first-level emergency state is defined as the collision sensor detecting that the vehicle is in a low-intensity collision state based on the vehicle body safety state, or / and, turning on an emergency escape switch.

[0022] Furthermore, the secondary emergency state is defined as the battery management system detecting that the vehicle power supply is in a self-ignition state, or, based on the vehicle body safety state, the collision sensor detects that the vehicle is in a high-intensity collision state, or / and, two emergency escape switches are turned on.

When the occupants are unable to move, the central control unit can automatically start the escape system to quickly unlock the self-priming lock, pop out the hidden door handle, and open the window, so that external rescue personnel can rescue the occupants in the vehicle in time, thereby enabling the rescue and escape system to respond quickly in a variety of emergency situations.

[0024] Furthermore, the vehicle rescue and escape system and method provided by the present invention also include a backup power supply unit, which includes a centralized backup power supply connected to the vehicle's power supply and an edge distributed backup power supply connected to the trigger signal input unit and the execution unit, so that when the vehicle's power supply is abnormal, the central control unit can control the centralized backup power supply to power the rescue and escape system; even if the centralized backup power supply cannot supply power, the edge distributed backup power supply can still ensure the normal operation of the trigger signal input unit and the execution unit, thereby improving the reliability and safety of the rescue and escape system.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0034] See also Figure 1 , which shows an example of the vehicle rescue and escape system provided by the present invention.

[0035] As can be seen from the figure, the vehicle rescue escape system of this example mainly includes a trigger signal input unit 100, an execution unit 200, a backup power supply unit 300 and a central control unit 400.

[0036] The trigger signal input unit 100 includes a detection component 110 and an emergency escape switch 120 arranged in the vehicle, and is configured to detect the vehicle's motion state, collision intensity, power supply state and spontaneous combustion state of the vehicle's power supply in real time, and can also obtain the open and closed state of the emergency escape switch 120 to generate a trigger signal; the execution unit 200 is configured to control the locking state of the vehicle's self-priming lock, the pop-up state of the hidden door handle, and the opening state of the door and window; so that the occupants in the vehicle can manually start the rescue escape system through the emergency escape switch 120. When the occupants are unable to move, the detection component 110 can automatically start the escape system to quickly unlock the self-priming lock, pop out the hidden door handle, and open the window, so that external rescue personnel can rescue the occupants in the vehicle in time, thereby enabling the rescue escape system to respond quickly in various emergency situations.

[0037] Furthermore, the backup power supply unit 300 includes a centralized backup power supply 310 connected to the vehicle's power supply and an edge distributed backup power supply 320 connected to the trigger signal input unit 100 and the execution unit 200; the central control unit 400 is connected to the trigger signal input unit 100, the execution unit 200 and the backup power supply unit 300, and is configured to collect and analyze the trigger signal of the trigger signal input unit 100 to control the working status of the execution unit 200 and the backup power supply unit 300; when the vehicle is damaged and spontaneously combusts and cannot be powered normally, the central control unit 400 can control the centralized backup power supply 310 to supply power to the vehicle's power supply. Even when the centralized backup power supply 310 cannot supply power, the edge distributed backup power supply 320 can still ensure the normal operation of the trigger signal input unit 100 and the execution unit 200, thereby improving the reliability and safety of the rescue and escape system.

[0038] Among them, the detection component 110 of the trigger signal input unit 100 includes a battery management system 111, a collision sensor 112 and an inertial measurement sensor 113 arranged in the vehicle, so that the battery management system 111, the collision sensor 112 and the inertial measurement sensor 113 can cooperate to detect the vehicle status in real time.

[0039] Specifically, the battery management system 111 is configured to perform real-time detection of the vehicle's power supply, control the charging and discharging of the vehicle's power supply, and determine whether the vehicle's power supply is supplying power normally. When the battery management system 111 detects that the vehicle's power supply is abnormal, it generates a trigger signal and inputs it to the central control unit 400. At the same time, the battery management system 111 can also detect in real time whether the vehicle's power supply is in a spontaneous combustion state, and generate a trigger signal corresponding to the spontaneous combustion state and the non-spontaneous combustion state and input it to the central control unit 400, so that the central control unit 400 controls the execution unit 200 to work accordingly.

[0040] Furthermore, the collision sensor 112 is configured to monitor the collision intensity of the vehicle in real time when the vehicle collides, determine whether the vehicle is in a low-intensity collision state or a high-intensity collision state, and generate a corresponding trigger signal to input into the central control unit 400.

[0041] Accordingly, the inertial measurement sensor 113 is configured to detect the three-axis acceleration and three-axis angular velocity of the vehicle in real time, and process and analyze the three-axis acceleration and three-axis angular velocity to determine whether the vehicle is flipping over and obtain the vehicle's driving speed. A safety speed threshold is preset in the inertial measurement sensor 113. When the inertial measurement sensor 113 detects that the vehicle is in a non-flipping state and the vehicle speed is lower than the safety speed threshold, a trigger signal is generated and input to the central control unit 400, so that the central control unit 400 controls the execution unit 200 to work according to the corresponding trigger signal when the vehicle is stable, thereby ensuring the safety of the occupants.

[0042] Here, as an example, the preset safety speed threshold of the inertial measurement sensor 113 is 20 km / h, and the safety speed threshold can also be adaptively adjusted according to specific actual conditions.

[0043] The battery management system 111, collision sensor 112 and inertial measurement sensor 113 thus constructed can cooperate to obtain the vehicle power supply status and spontaneous combustion status, collision intensity and movement status of the vehicle in real time, and generate corresponding trigger signals, so that the detection component 110 can input the trigger signal to the central control unit 400 in real time. The central control unit 400 can receive the trigger signal corresponding to each detection component respectively, and control the execution unit 200 to work according to the corresponding trigger signal, so that when the occupants in the vehicle are unable to move, the central control unit 400 can automatically start the escape and rescue system in various emergency situations when the vehicle is in a stable state, and external rescue personnel can quickly help the occupants in the vehicle escape, thereby improving the reliability and safety of the escape and rescue system.

[0044] Furthermore, the trigger signal input unit 100 also includes an emergency escape switch 120. There are at least two emergency escape switches 120, which are distributed in the same or different positions in the vehicle, so that the occupants in the vehicle can manually input a trigger signal to the central control unit 400 through the emergency escape switch 120 to manually start the escape system.

[0045] At the same time, the occupants in the vehicle can turn on one or two emergency escape switches 120 to generate different trigger signals, so that the central control unit 400 can determine the emergency condition of the vehicle through the corresponding trigger signal, thereby correspondingly controlling the working state of the execution unit 200.

[0046] The emergency escape switch 120 thus constructed cooperates with the detection component 110 to realize the manual generation and self-generation of trigger signals by the trigger signal input unit 100, and manually and self-starts the execution unit 200 through the central control unit 400, thereby improving the reliability of the rescue escape system.

[0047] In order to enable the central control unit 400 to control the execution unit 200 to respond quickly, effectively open the doors and windows, enable the occupants in the vehicle to escape safely and quickly, and the rescue personnel outside the vehicle to rescue quickly, the execution unit 200 includes a self-priming lock controller 210, a hidden door handle controller 220, a door drive controller 230, a window breaking controller 240 and an external rescue controller 250, so that the self-priming lock controller 210, the hidden door handle controller 220, the window breaking controller 240, the door drive controller 230 and the external rescue controller 250 can respectively cooperate with the central control unit 400 to quickly open the doors and windows.

[0048] Specifically, the self-priming lock controller 210 is configured to control the locking and unlocking of the self-priming lock on the vehicle door, and the hidden door handle controller 220 is configured to control the pop-up of the hidden door handle on the vehicle door, so that the central control unit 400 can control the execution unit 200 to start the self-priming lock controller 210 and the hidden door handle controller 220 to unlock the self-priming lock and pop out the hidden door handle, so that the occupants in the vehicle can quickly push open the door to escape, and rescue personnel outside the vehicle can pull the hidden door handle to quickly open the door and rescue the occupants in the vehicle.

[0049] Furthermore, the door drive controller 230 includes an electric door controller and an electric spring door controller. The electric door controller is configured to be able to fully open the car door, and the electric spring door controller is configured to be able to bounce the car door to a certain angle, preferably to be able to bounce the car door 10°, so that the electric door controller and the electric spring door controller can cooperate to adapt to different rescue scenarios. At the same time, the central control unit 400 can control the execution unit 200 to start the door drive controller 230 after the self-priming lock controller 210 is unlocked, so as to quickly open the car door and realize rapid rescue and escape.

[0050] In order to enable the rescue escape system to effectively open an escape channel, the execution unit 200 also includes a window breaking controller 240, which is composed of a window breaking device arranged on the vehicle window. As a rescue backup redundancy of the execution unit 200, the window breaking controller 240 is configured to apply pressure to the vehicle window to break the vehicle window, so that the central control unit 400 can control the execution unit 200 to start the window breaking controller 240 and break the vehicle window when the self-priming lock controller 210 and the door drive controller 230 cannot open the vehicle door normally, thereby providing a window escape channel, ensuring that the occupants in the vehicle can quickly escape through the vehicle window, and improving the reliability of the rescue escape system.

[0051] Since some vehicles are not equipped with door handles, in order to facilitate rescue work by rescue personnel outside the vehicle, the execution unit 200 also includes an external rescue controller 250 arranged outside the vehicle. The external rescue controller 250 is composed of a lighting prompt light and a door opening button, and is preferably arranged on the B-pillar of the vehicle, so that the central control unit 400 can control the execution unit 200 to start the external rescue controller 250, so that the external rescue controller 250 is in a rescue prompt state. External rescue personnel can quickly find the vehicle according to the guidance of the lighting prompt light, and open the door by pressing the door opening button, thereby improving rescue efficiency.

[0052] The self-priming lock controller 210, hidden door handle controller 220, door drive controller 230, broken window controller 240 and external rescue controller 250 thus constructed cooperate to form the execution unit 200, so that the central control unit 400 can independently control the operation of any controller in the execution unit 200 to achieve different rescue and escape effects, thereby improving the reliability and safety of the rescue and escape system.

[0053] In order to ensure that the trigger signal input unit 100, the execution unit 200 and the central control unit 400 can work stably in emergency situations, such as when the vehicle's power supply spontaneously combusts or is damaged, the rescue escape system also includes a backup power supply unit 300. The backup power supply unit 300 serves as a backup driving power supply for the rescue escape system and is configured to provide the power required for normal operation of the rescue escape system when the vehicle's power supply fails to supply power normally, thereby ensuring the reliability of the rescue escape system.

[0054] Specifically, the backup power supply unit 300 includes a centralized backup power supply 310, which is connected to the vehicle power supply and is preferably composed of a storage battery or a lithium battery. When the battery management system 111 in the trigger signal input unit 100 detects that the vehicle power supply is in an abnormal power supply state, the central control unit 400 can control the centralized backup power supply 310 to supply power to the entire rescue escape system, so that the rescue escape system can work normally and ensure that the occupants in the vehicle can escape smoothly.

[0055] Furthermore, the backup power supply unit 300 also includes an edge distributed backup power supply 320, which is preferably composed of a supercapacitor and is respectively connected to each detection component 110 and the emergency escape switch 120 in the trigger signal input unit 100 and each controller in the execution unit 200, as a backup redundancy for powering each detection component 110 and each controller. The edge distributed backup power supply 320 is configured to continuously supply power to each detection component 110, the emergency escape switch 120 and each controller when the centralized backup power supply 310 fails, thereby ensuring that each detection component 110, the emergency escape switch 120 and each controller can operate normally.

[0056] Here, the storage capacity of the edge distributed backup power supply 320 is preferably adapted to the power required for each detection component 110 and each controller to work normally for 24 hours, so as to ensure that the rescue escape system can still work normally in an emergency.

[0057] The backup power supply unit 300 thus constructed provides double protection for the stable operation of the rescue and escape system through the cooperation of the centralized backup power supply 310 and the edge distributed backup power supply 320, thereby further improving the reliability and safety of the rescue and escape system.

[0058] In order to enable the central control unit 400 to stably cooperate with the trigger signal input unit 100, the execution unit 200 and the backup power supply unit 300, the central control unit 400 is configured to control the operation of the corresponding controllers in the backup power supply unit 300 and the control execution unit 200 according to the trigger signal corresponding to each detection component of the trigger signal input unit 100, so as to realize different rescue and escape plans corresponding to different emergency situations, thereby realizing the reliability and safety of the rescue and escape system.

[0059] Specifically, the central control unit 400 is configured with a vehicle body safety state, a first-level emergency state and a second-level emergency state. These three vehicle states correspond to different trigger signals and different controllers, respectively, so that the central control unit 400 can judge the currently collected trigger signal as a vehicle body safety state, a first-level emergency state or a second-level emergency state to correspond to the working state of the control execution unit 200.

[0060] Combination Figure 2 , where the vehicle body safety state is defined as the inertial measurement sensor 113 in the trigger signal input unit 100 detecting that the vehicle is in a non-rollover state and the vehicle speed is lower than the safety speed threshold. At the same time, the battery management system 111 detects that the vehicle is in a non-spontaneous combustion state. At this time, the central control unit 400 determines that the vehicle is in a vehicle body safety state. The execution unit 200 does not have a controller corresponding to the vehicle body safety state and does not perform any execution.

[0061] Furthermore, the first-level emergency state is defined as that, based on the vehicle body safety state, the collision sensor 112 in the trigger signal input unit 100 detects a vehicle collision and determines it to be a low-intensity collision. At this time, the central control unit 400 determines that the vehicle is in a first-level emergency state.

[0062] Correspondingly, the occupant turns on an emergency escape switch 120 in the trigger signal input unit 100, and the central control unit 400 also determines that the vehicle is in a level one emergency state.

[0063] Here, the trigger signal generated by the low-severity collision detected by the collision sensor 112 and the activation of an emergency escape switch 120 can be input into the central control unit 400 individually or synchronously, so that the central control unit 400 can determine that the vehicle is in a first-level emergency state when a low-severity collision or the activation of an emergency escape switch 120 occurs individually, and can also determine that the vehicle is in a first-level emergency state when a low-severity collision and the activation of an emergency escape switch 120 occur simultaneously.

[0064] In coordination with this, the self-priming lock controller 210 and the hidden door handle controller 220 in the execution unit 200 correspond to the first-level emergency state, so that when the central control unit 400 determines the first-level emergency state, it controls the execution unit 200 to start the self-priming lock controller 210 and the hidden door handle controller 220 to unlock the self-priming lock and pop out the hidden door handle, ensuring that the occupants can escape through the car door and be rescued in the first-level emergency state.

[0065] Furthermore, the level 2 emergency state is defined as the battery management system 111 detecting that the vehicle is in a spontaneous combustion state, at which time the central control unit 400 determines that the vehicle is in a level 2 emergency state.

[0066] On the contrary, based on the battery management system 111 detecting that the vehicle is in a non-spontaneous combustion state and the vehicle body is in a safe state, the collision sensor 112 in the trigger signal input unit 100 detects that the vehicle has collided and determines it to be a high-intensity collision. At this time, the central control unit 400 determines that the vehicle is in a level 2 emergency state.

[0067] At the same time, the occupant turns on the two emergency escape switches 120 in the trigger signal input unit 100, and the central control unit 400 also determines that the vehicle is in a level 2 emergency state.

[0068] Here, the trigger signals generated by the high-intensity collision detected by the collision sensor 112 and the opening of the two emergency escape switches 120 can be input into the central control unit 400 separately or simultaneously, so that the central control unit 400 can determine that the vehicle is in a secondary emergency state when a high-intensity collision or the opening of the two emergency escape switches 120 occur separately, and can also determine that the vehicle is in a secondary emergency state when a high-intensity collision and the opening of the two emergency escape switches 120 occur simultaneously.

[0069] Similarly, the spontaneous combustion state detected by the battery management system 111 and the trigger signal generated by turning on the two emergency escape switches 120 can be input separately or synchronously into the central control unit 400, so that the central control unit 400 can determine that the vehicle is in a secondary emergency state when the spontaneous combustion state or the turning on of the two emergency escape switches 120 occur separately, and can also determine that the vehicle is in a secondary emergency state when the spontaneous combustion state and the turning on of the two emergency escape switches 120 occur simultaneously.

[0070] In coordination with this, the self-priming lock controller 210, the hidden door handle controller 220 and the external rescue controller 250 in the execution unit 200 correspond to the secondary emergency state, so that when the central control unit 400 determines the secondary emergency state, it controls the execution unit 200 to start the self-priming lock controller 210, the hidden door handle controller 220 and the external rescue controller 250 to unlock the self-priming lock, pop out the hidden door handle, and at the same time turn on the rescue prompt state of the external rescue controller 250 to ensure that the occupants can escape through the door in the secondary emergency state, and the external rescue personnel can quickly find the vehicle according to the lighting prompt light and open the door to carry out rescue.

[0071] Furthermore, in order to ensure that the occupants can escape quickly and effectively in the secondary emergency state, the central control unit 400 will also determine the working status of the self-priming lock controller 210 in the secondary emergency state. If the self-priming lock controller 210 unlocks the self-priming lock normally, the central control unit 400 will control the execution unit 200 to start the door drive controller 230 to quickly open the door and achieve rapid rescue and escape.

[0072] Furthermore, if the self-priming lock controller 210 cannot unlock the self-priming lock normally or the door drive controller 230 cannot open the door normally, in order to ensure the efficiency of rescue and escape, the central control unit 400 will control the execution unit 200 to start the window breaking controller 240, break the car window, provide a car window escape channel, ensure that the occupants in the car can escape quickly through the car window, and improve the reliability of the rescue and escape system.

[0073] Therefore, the central control unit 400 controls the operation of different controllers in response to the trigger signals of different detection components, ensuring that the vehicle can implement corresponding rescue and escape plans in the vehicle body safety state, the first level emergency state and the second level emergency state, thereby improving the reliability and safety of the rescue and escape system.

[0074] At the same time, during the driving of the vehicle, the battery management system 111 in the trigger signal input unit 100 can detect the power supply status of the vehicle's power supply in real time. If the battery management system 111 detects that the vehicle's power supply is in an abnormal power supply state, the central control unit 400 can control the backup power supply unit 300 to power the rescue escape system.

[0075] Furthermore, the rescue and escape system can be configured to communicate between the central control unit 400 and the trigger signal input unit 100, the execution unit 200 and the backup power supply unit 300 in accordance with the architecture of different vehicles by means of controller area network bus (CAN), local interconnect network (LIN) or hard wire, and can be configured to communicate in at least two ways, so that the communication connections between the central control unit 400 and the trigger signal input unit 100, the execution unit 200 and the backup power supply unit 300 are provided with communication backup redundancy to improve coordination stability.

[0076] The central control unit 400 thus constructed can not only ensure that the backup power supply unit 300 can work normally in an emergency, but also implement rescue and escape plans for the vehicle in different emergency situations, and is configured with a variety of backup redundancy plans to cope with complex emergency environments and ensure the safety of passengers.

[0077] Thus, the vehicle rescue and escape system provided by the present invention is formed.

[0078] The present invention also provides a vehicle rescue escape method, based on the vehicle rescue escape system composed of the above scheme, combined with Figure 2 , rescue escape methods include:

[0079] When the central control unit 400 collects and analyzes the trigger signal of the trigger signal input unit 100 and determines that the vehicle power supply is in an abnormal power supply state, it controls the backup power supply unit 300 to operate.

[0080] Specifically, during the driving of the vehicle, the battery management system 111 in the trigger signal input unit 100 detects the power supply status of the vehicle's power supply in real time. When it detects that the vehicle's power supply is in an abnormal power supply state, it generates a trigger signal and inputs it into the central control unit 400, so that the central control unit 400 controls the centralized backup power supply 310 in the backup power supply unit 300 to power the rescue escape system.

[0081] Furthermore, the battery management system 111 detects the power supply status of the centralized backup power supply 310 in real time. When it is detected that the centralized backup power supply 310 is in an abnormal power supply state, a trigger signal is generated and input into the central control unit 400, so that the central control unit 400 controls the edge distributed backup power supply 320 in the backup power supply unit 300 to power the trigger signal input unit 100 and the execution unit 200, thereby ensuring that the rescue escape system can operate normally.

[0082] At the same time, the central control unit 400 collects and analyzes the trigger signal of the trigger signal input unit 100, determines the vehicle state, and controls the working state of the execution unit 200 corresponding to the vehicle body safety state, the first level emergency state and the second level emergency state.

[0083] Specifically, if the inertial measurement sensor 113 of the trigger signal input unit 100 detects that the vehicle is in a non-flipping state and the vehicle speed is lower than the safety speed threshold, and at the same time, the battery management system 111 detects that the vehicle is in a non-spontaneous combustion state, the central control unit 400 determines that the vehicle is in a safe state and does not perform any execution.

[0084] When the central control unit 400 determines that the vehicle is in a safe state, if the collision sensor 112 detects a collision of the vehicle and determines it to be a low-intensity collision, or / and at the same time, the occupant turns on an emergency escape switch 120 in the trigger signal input unit 100, the central control unit 400 determines that the vehicle is in a level 1 emergency state, and controls the execution unit 200 to start the self-priming lock controller 210 and the hidden door handle controller 220 to unlock the self-priming lock and pop out the hidden door handle.

[0085] If the battery management system 111 detects that the vehicle is in a spontaneous combustion state, or when the central control unit 400 determines that the vehicle is in a safe state, the collision sensor 112 detects that the vehicle has collided and determines it to be a high-intensity collision, or / and at the same time, the occupant turns on the two emergency escape switches 120 in the trigger signal input unit 100, the central control unit 400 determines that the vehicle is in a secondary emergency state, and controls the execution unit 200 to start the self-priming lock controller 210, the hidden door handle controller 220 and the external rescue controller 250 to unlock the self-priming lock, pop out the hidden door handle, and turn on the external lighting indicator light and the door opening button.

[0086] At the same time, the central control unit 400 determines the working status of the self-priming lock controller 210. If the self-priming lock controller 210 unlocks the self-priming lock normally, the central control unit 400 controls the execution unit 200 to start the door drive controller 230 to quickly open the door. If the self-priming lock controller 210 cannot unlock the self-priming lock normally or the door drive controller 230 cannot open the door normally, the central control unit 400 will control the execution unit 200 to start the window breaking controller 240 to break the window and provide an escape channel through the window.

[0087] This enables the rapid opening of vehicle windows and doors, helping occupants in the vehicle to escape quickly and rescue workers outside the vehicle to quickly carry out rescue.

[0088] The vehicle rescue escape system and method provided by the present invention adopts a trigger signal input unit 100, an execution unit 200, a backup power supply unit 300 and a central control unit 400 to cooperate with each other, and can manually start or automatically start the rescue escape system. The execution unit 200 is controlled to implement corresponding rescue escape plans in accordance with three vehicle states, and the rescue escape system is guaranteed to work normally when the vehicle power supply cannot be normally supplied. It can respond quickly to various emergency situations and has high reliability and safety.

[0089] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
