These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0030] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0031] The emergency escape system of a bus is an important part of the bus, and the reliability of the emergency escape system is related to the life safety of passengers. In the related art, the emergency escape system on the bus needs to be manually activated by pressing a button, or the escape passage needs to be manually opened using an escape device such as a hammer. When the bus is in an emergency, passengers may be unable to quickly and accurately find and operate the escape button or device due to panic. Especially for passengers who are not familiar with the structure of the vehicle, the operation may be more difficult. Manual operation requires a certain amount of time to complete, including steps such as finding the button, pressing the button or operating the escape device. In an emergency, every second is crucial, and a delay in time may result in the loss of escape opportunities. The manual button or escape device may malfunction due to long-term use, wear or improper maintenance, resulting in failure to start or operate normally in an emergency. Therefore, the above-mentioned emergency escape system has the problem of low safety performance, and there is an urgent need for a solution to open the escape passage in a timely, accurate and automatic manner when the vehicle is in a critical state.

[0032] An embodiment of the present application provides an emergency escape control system for a passenger bus, in which a collision monitoring component is provided to monitor whether the vehicle collides and sends a collision signal to a body controller when the vehicle collides. In addition, a body angle monitoring component is provided to monitor body angle data and send the body angle data to the body controller. When the body controller receives a collision signal or determines that the vehicle has overturned based on the body angle data, the emergency door opening system is controlled to perform a door opening operation and detect whether the door is successfully opened. If it is not successfully opened, the window breaking system is controlled to perform a window breaking operation to ensure the automatic opening of the escape passage, provide the necessary conditions for the smooth escape of the people in the vehicle, and improve the safety of the passenger bus.

[0033] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0034] Figure 1 Schematic diagram of the structure of the passenger car emergency escape control system provided in the embodiment of the application Figure 1 .like Figure 1 As shown, the bus emergency escape control system 10 includes:

[0035] A vehicle body controller 101, a collision monitoring component 102, a vehicle body angle monitoring component 103, an emergency door opening system 104, and a window breaking system 105 connected to the vehicle body controller 101; wherein:

[0036] The collision monitoring component 102 is used to monitor whether the vehicle has collided, and when a collision is detected, generates a collision signal corresponding to the collision based on the collected collision data and sends the collision signal to the vehicle body controller 101;

[0037] The vehicle body angle monitoring component 103 is used to collect the vehicle body angle data and send the vehicle body angle data to the vehicle body controller 101;

[0038] The body controller 101 is used to control the emergency door opening system 104 to perform the door opening operation when the vehicle is in a preset state, and to detect whether the door is successfully opened. If it is not successfully opened, the window breaking system 105 is controlled to perform the window breaking operation. The preset state includes receiving a collision signal, or determining that the vehicle has overturned based on the body angle data.

[0039] In some embodiments, the collision monitoring component 102 may specifically be a collision sensor, an accelerometer, a gyroscope, a pressure sensor, etc., which can detect whether the vehicle has collided based on the motion state of the vehicle.

[0040] Exemplarily, the collision monitoring component 102 is a collision sensor. With the vehicle's traveling direction as the front, the collision sensor monitors the vehicle's acceleration in the front-to-back direction, the left-to-right direction, and the up-to-down direction. When the acceleration value in the front-to-back direction is greater than 7.5g (g is the acceleration due to gravity), or the acceleration value in the left-to-right direction is greater than 7.5g, or the acceleration value in the up-to-down direction is greater than 7.5g, it is determined that the vehicle has collided, and a collision signal is generated and sent to the body controller 101.

[0041] In some embodiments, the vehicle body angle monitoring component 103 may be a device capable of measuring the vehicle body angle, such as a slope sensor, a gyroscope, an accelerometer, an inertial measurement unit, or a vehicle body height sensor.

[0042] Exemplarily, the vehicle body angle monitoring component 103 is a slope sensor, which collects the angle of the vehicle body relative to the horizontal plane and sends the vehicle body angle data to the vehicle body controller 101. When the vehicle body controller 101 determines that the vehicle body angle is greater than 45° based on the vehicle body angle data, it determines that the vehicle has overturned, controls the emergency door opening system 104 to open the door, and controls the window breaking system 105 to break the window.

[0043] The window breaking system 105 is installed on the vehicle window glass. When receiving the window breaking command transmitted by the vehicle body controller 101, it executes the action of breaking the vehicle window glass, making the vehicle window a usable escape route.

[0044] In some embodiments, the window breaking device supports both automatic and manual window breaking modes. Automatic window breaking involves breaking the window glass under the control of the vehicle body controller 101. In manual window breaking mode, a person presses a button on the window breaking device to initiate the window breaking action.

[0045] In some embodiments, the emergency door opening system 104 supports both manual and automatic opening modes. Automatic opening automatically opens the door under the control of the vehicle body controller 101. In manual opening mode, the emergency door opening system 104 opens the door when a person presses a door opening button located inside the vehicle.

[0046] When the vehicle's onboard power supply, such as KL30, KL15, or KL87, is powered on, the body controller 101, upon receiving a collision signal from the collision monitoring unit 102 or determining a rollover based on the body angle detected by the body angle monitoring unit 103, controls the emergency door opening system 104 to open the door, thereby opening the escape route and facilitating a smooth escape for the vehicle occupants. Furthermore, to ensure smooth door opening, the door status is monitored. In some emergency situations, the door may not open smoothly due to squeezing, obstructions, or other factors. In this case, if the door is detected to have failed to open smoothly, the window breaking device is activated to further ensure a clear escape route.

[0047] The bus emergency escape system provided in the embodiment of the present application monitors the collision or rollover of the vehicle through the collision monitoring component and the body angle monitoring component. The body controller responds to the collision signal sent by the collision monitoring component or the body angle sent by the body angle monitoring component, and timely and automatically controls the emergency door opening system and the window breaking system to open the escape passage to ensure the automatic opening of the escape passage, provide the necessary conditions for the smooth escape of the occupants, and improve the safety of the bus.

[0048] Figure 2 Schematic diagram of the bus emergency escape system structure provided in the embodiment of this application Figure 2 .like Figure 2 As shown, in a possible embodiment, the collision signal carries an alarm level indicating the intensity of the collision, and the emergency escape control system 10 further includes: a hydrogen bottle controller 106 connected to the collision monitoring component 102, and the hydrogen bottle controller 106 is used to execute a hydrogen supply cut-off operation when receiving a collision signal carrying an alarm level that is an alarm level requiring hydrogen cut-off.

[0049] In one embodiment, the collision monitoring component 102 determines different alarm levels based on the collision intensity. For example, the alarm level is determined to be level 1 in the case of a mild collision, level 2 in the case of a moderate collision, and level 3 in the case of a severe collision.

[0050] In a hydrogen-powered vehicle, the hydrogen tank controller 106 controls the vehicle's hydrogen supply. Hydrogen is a flammable gas. If the hydrogen supply is not cut off during a serious collision and there is a risk of fire, the hydrogen combustion will increase the difficulty of escape.

[0051] In one example, the collision monitoring component 102 detects a minor collision of the vehicle. At this time, there is no fire risk, and the alarm level is determined to be level one. The collision signal including the alarm level is sent to the hydrogen bottle controller 106. The hydrogen bottle controller 106 receives the collision signal and identifies that the alarm level is level one. It does not cut off the hydrogen supply, so that the vehicle can quickly resume normal operation after the inspection is completed.

[0052] In another example, the collision monitoring component 102 detects a moderate collision of the vehicle, determines the alarm level to be level two, and sends a collision signal including the alarm level to the hydrogen bottle controller 106. The hydrogen bottle controller 106 receives the collision signal and identifies the alarm level as level two, and then cuts off the hydrogen supply to avoid the risk of fire.

[0053] In another example, the collision monitoring component 102 detects a serious collision of the vehicle, determines that the alarm level is level three, and sends a collision signal including the alarm level to the hydrogen bottle controller 106. The hydrogen bottle controller 106 receives the collision signal and identifies that the alarm level is level three, and then cuts off the hydrogen supply to avoid the risk of fire.

[0054] In some embodiments, Figure 2 Each module is connected to the gateway for communication, and the communication between modules is realized through the gateway.

[0055] In the passenger bus emergency escape system provided in the embodiment of the present application, the collision monitoring component determines the alarm level according to the collision intensity, and sends a collision signal carrying the alarm level to the hydrogen bottle controller connected to the collision monitoring component. The hydrogen bottle controller controls the cutting off of the hydrogen supply according to the alarm level, thereby ensuring that the vehicle quickly returns to operation in the event of a minor collision, and avoiding the risk of fire caused by hydrogen combustion in the event of a moderate or severe collision, which makes escape difficult.

[0056] Continue to refer to Figure 2In one possible implementation, the collision signal carries an alarm level indicating the intensity of the collision. The bus emergency escape control system 10 further includes: a vehicle controller 107 connected to the collision monitoring component 102. The vehicle controller 107 is configured to execute a vehicle high-voltage power-down operation upon receiving a collision signal carrying an alarm level indicating that the vehicle needs to be powered down.

[0057] The vehicle controller 107 is the core control unit of the automotive electronic system, and is mainly responsible for coordinating functions such as the vehicle power system, energy management, safety monitoring and network communication.

[0058] A collision can damage wiring harnesses, cause insulation failure, or expose metal parts. If high-voltage power is not disconnected, firefighters, medical personnel, and other rescue workers, or passengers who come into contact with the vehicle body could be electrocuted. A collision can also cause a short circuit in high-voltage wiring, generating arcs or sparks that could ignite leaked battery electrolyte or flammable materials inside the vehicle. If high-voltage power continues to flow into a damaged battery pack, it can exacerbate the internal short circuit and trigger a thermal runaway chain reaction, causing the battery to violently combust or even explode.

[0059] In one embodiment, the collision monitoring component 102 determines different alarm levels based on the collision intensity. For example, the alarm level is determined to be level 1 in the case of a mild collision, level 2 in the case of a moderate collision, and level 3 in the case of a severe collision.

[0060] In one example, the collision monitoring component 102 detects that the vehicle has a minor collision. At this time, the collision intensity is relatively light, and the possibility of damage to the high-voltage components and batteries in the vehicle is relatively small. The alarm level is determined to be level one, and a collision signal including the alarm level is sent to the vehicle controller 107. The vehicle controller 107 receives the collision signal and recognizes that the alarm level is level one. It does not perform the high-voltage power operation, so that the vehicle can quickly resume normal operation after the inspection is completed.

[0061] In another example, the collision monitoring component 102 detects a moderate collision of the vehicle, determines the alarm level to be level two, and sends a collision signal including the alarm level to the vehicle controller 107. The vehicle controller 107 receives the collision signal and identifies the alarm level as level two, and then performs a high-voltage electric operation to avoid the risk of electric shock and battery thermal runaway.

[0062] In another example, the collision monitoring component 102 detects a serious collision of the vehicle, determines the alarm level to be level three, and sends a collision signal including the alarm level to the vehicle controller 107. The vehicle controller 107 receives the collision signal and identifies the alarm level as level three, and then performs a high-voltage electric operation to avoid the risk of electric shock and battery thermal runaway.

[0063] In the passenger bus emergency escape system provided in the embodiment of the present application, the collision monitoring component determines the alarm level according to the collision intensity, and sends the collision signal carrying the alarm level to the vehicle controller connected to the collision monitoring component. The vehicle controller controls the high voltage according to the alarm level, thereby ensuring that the vehicle quickly returns to operation in the event of a minor collision, and avoiding the risk of electric shock and battery thermal runaway caused by damage to high-voltage components in moderate or severe collisions.

[0064] Continue to refer to Figure 2 In one possible implementation, the collision signal carries an alarm level indicating the intensity of the collision. The bus emergency escape control system 10 further includes: an emergency call system 108 connected to the collision monitoring component 102. The emergency call system 108 is configured to execute an emergency call operation upon receiving a collision signal carrying an alarm level at which an emergency call needs to be executed.

[0065] For example, the emergency call system 108 may be a vehicle-mounted T-Box module, which enables interaction between the vehicle and a cloud platform and mobile phone software through wireless communication technology.

[0066] In one embodiment, the collision monitoring component 102 determines different alarm levels based on the collision intensity. For example, the alarm level is determined to be level 1 in the case of a mild collision, level 2 in the case of a moderate collision, and level 3 in the case of a severe collision.

[0067] For example, the collision monitoring component 102 detects a serious collision of the vehicle, determines that the alarm level is level three, and sends a collision signal including the alarm level to the emergency call system 108. The emergency call system 108 receives the collision signal and identifies that the alarm level is level three, and then performs an emergency call operation.

[0068] The bus emergency escape system provided in the embodiment of the present application is equipped with an emergency call system, which can trigger the emergency call operation of the emergency call system according to the collision intensity, ensuring timely call for rescue when a collision occurs, thereby improving the safety of the bus.

[0069] In one possible embodiment, the collision signal carries an alarm level indicating the intensity of the collision, and the bus emergency escape control system further includes: a display system 109 connected to the body controller 101, and the body controller 101 is configured to control the display system 109 to display danger warning information when receiving a collision signal carrying an alarm level that requires a danger warning.

[0070] Optionally, the display system 109 may be a road sign display screen outside the bus, which is arranged on the front, side or rear of the bus. The hazard warning includes displaying hazard warning information, flashing or projecting hazard warning symbols onto the ground.

[0071] The example of the collision monitoring component 102 generating a collision signal with different warning levels based on the collision intensity is the same as in the above embodiment and will not be repeated here. In some embodiments, the body controller 101 controls the display system 109 to display a hazard warning message based on the collision level carried in the received collision signal.

[0072] For example, the collision monitoring component 102 detects a serious collision of the vehicle, determines that the alarm level is level three, and sends a collision signal including the alarm level to the body controller. The body controller 101 receives the collision signal and identifies that the alarm level is level three, and then executes the control display system 109 to display the danger warning information.

[0073] The passenger bus emergency escape system provided in the embodiment of the present application is equipped with a display system that can execute danger prompts according to the alarm level, ensuring that the escape route for occupants of the vehicle is unobstructed while providing warnings to other traffic participants, thereby reducing the risks brought to other traffic participants.

[0074] In a possible embodiment, the bus emergency escape control system further includes: a braking system 110 connected to the collision monitoring component 102, and the braking system 110 is used to perform a deceleration operation to adjust the vehicle speed to a safe escape speed after receiving a collision signal.

[0075] After the first collision, the vehicle may continue to slide due to inertia, such as hitting a wall and bouncing back to the center of the road, or rushing forward after a high-speed rear-end collision. The braking system automatically applies braking force to reduce the vehicle speed to a speed close to the safe escape speed, avoiding secondary collisions with pedestrians, oncoming vehicles or fixed obstacles, and also providing the prerequisite for people in the car to escape through the escape route.

[0076] For example, after the collision monitoring component 102 detects a vehicle collision, it sends a collision signal to the braking system 110, and the braking system adjusts the vehicle speed to below 3 km / h. Furthermore, emergency escape devices such as the emergency door opening system and the window breaking system execute the operation of opening the emergency escape passage.

[0077] In the bus emergency escape system provided in the embodiment of the present application, the collision monitoring component is connected to the brake system, and the collision signal is transmitted to the brake system in a timely manner, so that the bus can reduce its speed to a safe escape speed in time after a collision, providing the prerequisite for the escape of people in the bus.

[0078] In a possible implementation, the collision data includes collision acceleration, and the collision monitoring component is specifically configured to:

[0079] Based on the preset constraints corresponding to different alarm levels, the target alarm level corresponding to the collision is determined according to the collected collision acceleration; and a collision signal corresponding to the collision is generated according to the target alarm level.

[0080] For example, when the collected collision acceleration is greater than 3g and less than or equal to 7.5g, the alarm level is determined to be level 1; when the collected collision acceleration is greater than 7.5g and less than or equal to 15g, the alarm level is determined to be level 2; and when the collected collision acceleration is greater than 15g, the alarm level is determined to be level 3. A collision signal corresponding to the collision is generated based on the alarm level.

[0081] In one embodiment, when a collision occurs, the collision monitoring component determines the alarm level based on the collected acceleration, generates a collision signal, and sends the collision signal to the body controller, vehicle controller, hydrogen bottle controller, and braking system. Each of the above controllers or systems performs corresponding emergency operations based on the alarm level.

[0082] For example, when the collision acceleration collected by the collision monitoring component is greater than 3g and less than or equal to 7.5g, the alarm level is determined to be level one. The braking system receives the collision signal of the alarm level one and executes the operation of reducing the vehicle speed to a safe escape speed. The body controller executes the operation of controlling the emergency door opening system to open the door, the window breaking device to break the window, and the display system to display the danger warning information. When the collision acceleration collected by the collision monitoring component is greater than 7.5g and less than or equal to 15g, the alarm level is determined to be level two. The braking system executes the operation of reducing the vehicle speed to a safe escape speed, and the body controller executes the control The emergency door opening system opens the door, the window breaking device breaks the window, the display system displays a danger warning message, the hydrogen bottle controller cuts off the hydrogen supply, and the vehicle controller performs a high-voltage power operation; when the collision acceleration collected by the collision monitoring device is greater than 15g, the alarm level is determined to be level three, the braking system reduces the vehicle speed to a safe escape speed, the body controller controls the emergency door opening system to open the door, the window breaking device breaks the window, the display system displays a danger warning message, the hydrogen bottle controller cuts off the hydrogen supply, the vehicle controller performs a high-voltage power operation, and the emergency call system performs an emergency call operation.

[0083] In one embodiment, the collision signal is sent in the form of a message, such as Figure 3 As shown, the message may include the collision sensor status and alarm level. The collision sensor status includes whether the collision sensor is online normally, whether the measured acceleration value exceeds the measurement threshold, and other abnormal information of the sensor.

[0084] In some embodiments, the collision sensor can determine whether the vehicle has rolled over based on acceleration values measured in different directions, and indicate whether the vehicle has rolled over in the collision signal message.

[0085] In some embodiments, the vehicle body angle monitoring component sends angle information in the form of a message, the message format is as follows: Figure 4 shown.

[0086] For example, the message of the collision signal is represented by 56 bits of data, wherein bits 0-7 represent the state of the collision sensor, bits 8-15 represent the alarm level, and bits 55-48 represent whether the vehicle rolls over.

[0087] The bus emergency escape system provided in the embodiment of the present application determines the collision level based on preset constraints and collision acceleration collected in real time, so that each component in the system can accurately and efficiently perform corresponding emergency operations according to the collision level, thereby improving the safety of the bus.

[0088] In a possible implementation, the collision monitoring component is a collision sensor, or the collision monitoring component is a controller of a six-axis state monitoring chip with a built-in collision sensor.

[0089] The six-axis state monitoring chip is the core component of the collision sensor. It integrates a three-axis accelerometer and a three-axis gyroscope into a single chip to achieve all-round and high-precision monitoring of the vehicle's motion state.

[0090] The six-axis state detection chip can be integrated into a controller, such as a vehicle posture monitoring controller, an active suspension controller, or an airbag controller.

[0091] The emergency escape system provided in the embodiment of the present application uses a collision sensor or a controller of a six-axis state monitoring chip with a built-in collision sensor to monitor the collision state of the vehicle, thereby accurately obtaining the collision state of the vehicle.

[0092] In one possible implementation, the vehicle body controller is connected to the collision monitoring component, the vehicle body angle monitoring component, the emergency door opening system, and the window breaking system via a hard line or a CAN bus.

[0093] The CAN bus offers advantages such as strong real-time performance, long transmission distances, strong resistance to electromagnetic interference, and low cost. Hard wiring offers the advantages of fast and stable transmission, low installation costs, and low maintenance.
