The terms "one embodiment" and "an embodiment" mean "at least one embodiment". The term "another embodiment" means "at least one other embodiment". The terms "first", "second", etc. may refer to different or the same objects. Other definitions may be included below, whether explicit or implicit. Unless the context clearly indicates otherwise, the definition of a term is consistent throughout the specification.
[0022] like Figure 1 As shown, an embodiment of the present invention provides a vehicle window breaking method, comprising: Step S102: If the vehicle speed is detected to be greater than a preset speed, the window breaking device enters an open state.
[0023] Specifically, while the vehicle is in motion, the vehicle control unit continuously detects the vehicle speed. When the vehicle speed exceeds a preset speed threshold, the window breaking device is activated and turned on. The preset speed can be set based on statistics of high-speed collision accidents. For example, it can be set to 30 (km / h) based on the collision fatality rate. The preset speed can also be adjusted dynamically, such as after road type adaptation: the current road (such as highways or urban roads) is identified through GPS / ADAS map data, and the threshold is dynamically adjusted (such as lowering it to 20km / h on highway sections and increasing it to 40km / h on congested sections). Adjustments can also be made in abnormal weather conditions, such as lowering the threshold in rainy and snowy weather (due to reduced road adhesion, the risk of low-speed collisions is higher).
[0024] Furthermore, if a vehicle's speed exceeds a preset speed, it can detect not only the vehicle's own speed but also the speeds of nearby vehicles. The vehicle's onboard camera continuously collects speed data within the surrounding area. If a vehicle within a preset range (e.g., 0.5 meters) is traveling at speeds exceeding 30 km / h, the window-breaking mechanism is activated, shifting to the active state. This ensures that the window-breaking mechanism can be activated promptly in the event of a collision caused by excessive speed, as well as in the event of a collision with another vehicle. Furthermore, the window-breaking mechanism is set to activate when the vehicle's speed exceeds 30 km / h (according to data, collisions below this speed typically do not result in serious accidents). This avoids the waste of power that would otherwise be left on. It activates only when the vehicle's speed exceeds 30 km / h, creating a risk of a serious collision. This prevents potential collisions, conserving resources, and ensuring timely window breaking in the event of a collision, protecting the vehicle's occupants.
[0025] Step S104 , in the on state, when a collision signal is detected, corresponding collision data is collected, wherein the collision data includes the collision severity level and the vehicle slope.
[0026] Specifically, when the window breaking device enters the open state and a collision signal is detected, it indicates that the vehicle has been involved in a collision accident, and corresponding collision data is collected. The collision severity level in the collision data can be determined based on a series of collision data. For example, the collision severity level in the collision accident can be comprehensively determined by combining the collision location, collision time, collision acceleration, and deformation data. The collision location can include frontal collision, side collision, rear-end collision, etc. Different parts can withstand different collision times and collision accelerations. For example, the collision intensity that the A-pillar and B-pillar of a vehicle can withstand is not the same. The collision intensity that the vehicle can withstand can be determined based on the vehicle's own properties. Further combination with deformation data can further determine the collision severity level of the vehicle in the collision accident. Among them, the collision severity level can be divided into three levels: low, medium and high. Taking a head-on collision as an example, the acceleration peak of a low-level collision is 5~8g, and the duration is <20ms; the acceleration peak of a medium-level collision is 8~12g, and the duration is 20~50ms; the acceleration peak of a high-level collision is >12g, and the duration is >50ms. Then, combined with the vehicle deformation data, the current collision severity level is further confirmed.
[0027] In addition, the collision data also includes the vehicle's current slope, that is, the current degree of the vehicle's roll. The gyroscope and accelerometer can be used to calculate the vehicle's current pitch and roll angles, thereby determining the current degree of the vehicle's roll. For example, if the roll angle is greater than 45° or the pitch angle is greater than 60°, the vehicle is considered to have rolled over.
[0028] Step S106: When the collision severity level is greater than a first preset level and the vehicle slope is less than a preset slope, the activated window breaking device enters a standby state and detects whether an unlocking signal is received within a first time period.
[0029] Specifically, when the collision severity level is greater than a first preset level and the vehicle's slope is less than a preset slope, the collision is considered severe and the vehicle has not flipped. The first preset level may be intermediate, posing a certain risk to the safety of the occupants. A window-breaking rescue operation can be planned in a subsequent step. The window-breaking device is activated and enters a standby state, awaiting instructions from the occupants. Furthermore, the vehicle must remain in a non-flipped state. If the vehicle flips, gravity may prevent the windows from opening properly. Stopping the process at this point prevents ineffective operation and may injure occupants by breaking the windows. Therefore, the window-breaking device must be activated and enters a standby state only when the vehicle's slope is less than the preset slope, meaning the vehicle has not flipped.
[0030] Furthermore, after the window breaking device is activated and enters the standby state, it detects whether an unlocking signal is received within a first time period. The unlocking signal is generated by a occupant's own unlocking behavior, such as when a door is locked and the occupant uses other methods to open the door, such as the backup door unlocking method provided by some models of vehicles. Receiving the unlocking signal indicates that the occupant has likely escaped or is preparing to escape, eliminating the need for window breaking. The first time period can be set to 2 to 5 seconds.
[0031] Step S108: When no unlocking signal is received within the first time period, the window breaking device is activated in response to an activation signal from the vehicle occupant to complete the window breaking.
[0032] Specifically, if no unlock signal is received within a first time period, indicating that the occupant is unable to escape independently, the window-breaking device is activated in response to an activation signal from the bound person, completing the window-breaking operation. The activation signal can be a voice command from the occupant, such as keywords like "break window" or "break the car window," and can also specify a specific window to be broken. Alternatively, the window-breaking operation can occur automatically after a fixed time period. When the window-breaking device receives the aforementioned keywords, it is activated to complete the window-breaking operation. The window-breaking operation can involve activating an electromagnetic ejection or high-pressure gas window-breaking device to shatter a specific window (such as the front quarter window or the opposite side window).
[0033] Furthermore, when the collision severity level exceeds a second preset level (the second preset level is greater than the first preset level, which can be a high level), the collision may be more severe, and the occupants may become unconscious. The system then uses devices such as an infrared camera (detecting facial movements / pupil reactions), a steering wheel grip sensor (detecting the driver's active control), and a seatbelt pressure sensor (to determine if the occupant is in a normal sitting position) to detect unconsciousness. If unconsciousness is detected, the system then checks whether an unlock signal is received within a second time period. This second time period can be set to 2 seconds, representing the emergency response window for unconsciousness. If no unlock signal is received within the second time period, the corresponding external window breaking device is activated. For example, the external window breaking device can be configured to activate the window breaking mechanism by pressing and holding the window breaking button on the vehicle's outer B-pillar for 2 seconds. This allows for dynamic adjustment of the response strategy based on the severity of the collision. By leveraging multi-sensor fusion to determine unconsciousness, the system provides a rapid window-breaking channel for professional rescue personnel while the occupant is unconscious and self-rescuing.
[0034] An embodiment of the present invention provides a vehicle window breaking method. When a vehicle speed exceeds a preset speed, the window breaking device enters an active state. When a collision signal is detected in the active state, corresponding collision data is collected, including the collision severity level and the vehicle slope. When the collision severity level exceeds a first preset level and the vehicle slope is less than a preset slope, the window breaking device is activated to enter a standby state and detect whether an unlocking signal is received within a first time period. If no unlocking signal is received within the first time period, the window breaking device is activated in response to an activation signal from a vehicle occupant to complete the window breaking. This method can help vehicle occupants escape from the vehicle in a collision accident when the vehicle door is locked and cannot be opened, or when the vehicle occupants are unable to escape due to the accident. This allows the vehicle occupants to escape from the vehicle in a timely manner or improves the rescue efficiency of people outside the vehicle, thereby increasing the possibility of survival in the vehicle collision accident.
[0035] Furthermore, in another embodiment, a vehicle window breaking method may further include: When the collision severity level is greater than a first preset level and the vehicle slope is greater than a preset slope, detecting whether the occupant is in an unconscious state; When the occupant is not in an unconscious state, detecting whether an unlocking signal is received within a first time period, and activating a warning device if no unlocking signal is received; When the occupant is in an unconscious state, it is detected whether an unlocking signal is received within a second time period, and if the unlocking signal is not received, the alarm device is activated.
[0036] In this embodiment, when the collision severity level is greater than a first preset level and the vehicle's slope is greater than a preset slope, indicating a severe collision and a rollover, window-breaking rescue is unavailable. The system then detects whether the occupant is unconscious. If the occupant is awake, it checks whether an unlock signal is received within a first timeframe (the average unlocking reaction time for awake occupants). If no unlock signal is received, indicating that the occupant is unable to activate the warning device while awake. The warning device is activated. On the other hand, if the occupant is unconscious, it checks whether an unlock signal is received within a second timeframe (the emergency medical rescue response window). If no unlock signal is received, indicating that the occupant is unable to self-rescue, the warning device is activated. In-vehicle warning devices may include in-vehicle audible and visual alarms, remote rescue notifications, and mobile phone text messaging. This allows the handling strategy to be dynamically adjusted after the vehicle posture is flipped. For the processing of relevant information such as the first duration, the second duration, and the unlocking signal, corresponding data detection can also be performed when the window-breaking device fails to work, so as to protect the safety of the occupants in the car as much as possible in a collision accident.
[0037] See Figure 2 , Figure 2This is a schematic diagram of the structure of a vehicle window breaking system provided in an embodiment of the present application. Figure 2 As shown, the system includes: The detection module S202 is used to detect that the vehicle speed is greater than a preset speed, and the window breaking device enters the open state; A collision module S204 is configured to collect corresponding collision data when a collision signal is detected in the turned-on state, wherein the collision data includes a collision severity level and a vehicle slope; A preparation module S206 is configured to, when the collision severity level is greater than a first preset level and the vehicle slope is less than a preset slope, activate the window breaking device to enter a preparation state and detect whether an unlocking signal is received within a first time period; The first window breaking module S208 is used to activate the window breaking device to complete the window breaking in response to the activation signal of the bound person when no unlocking signal is received within the first time period.
[0038] In another embodiment, a vehicle window breaking system further includes: an occupant module, configured to collect the occupant status of the vehicle occupant when the collision severity level is greater than a second preset level, and detect whether an unlocking signal is received within a second time period when the occupant status is unconscious, the second preset level being greater than the first preset level; The second window breaking module is used to activate the vehicle's external window breaking device corresponding to the window breaking device to enter the open state when no unlocking signal is received within the second time period.
