[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Application Overview

[0032] Existing human protection solutions based on Automatic Emergency Braking (AEB) and hood hinges have several significant drawbacks. First, these systems typically use explosive bolts as the unlocking mechanism. Explosive bolts generate a large amount of heat and gas during operation, rapidly creating immense pressure that causes the bolt to break or separate within a very short time. As disposable components, explosive bolts need to be replaced after each trigger, significantly increasing the cost of active human protection and limiting the system's reusability.

[0033] Secondly, the system has extremely high requirements for collision accident detection, relying on high-precision sensors and complex control algorithms to ensure accurate triggering of the protection mechanism at the appropriate time. Any slight error or delay may lead to false triggering or untimely protection, which not only affects the reliability of the system but may also cause unnecessary economic losses or safety hazards.

[0034] Furthermore, to minimize the risk of accidental activation, current human protection strategies involve popping up the hood only after a collision has occurred. In practice, due to the overlap in time, the moment the human head collides with the hood may coincide with the moment the hood begins to pop up. This means that the hood may come into contact with the human head before it has fully popped up, potentially causing additional impact and further aggravating the injury.

[0035] To address the aforementioned issues, this application proposes an improved active human protection method. By acquiring sensor data related to the surrounding environment of the target vehicle, it determines whether a collision is imminent between the front of the vehicle and a human. If a collision is imminent, a reusable release structure unlocks the hood lock from a fully locked position to a partially locked position within a preset time. When the hood lock is in the partially locked position, the hood cannot be opened directly, and a deformation buffer space exists beneath the hood, effectively protecting the human body.

[0036] Compared to traditional explosive bolt solutions, this method not only reduces maintenance costs but also allows for improved system response speed and accuracy by lowering the action threshold, avoiding additional injury risks caused by delays in hood pop-up. Furthermore, by improving existing manual pull-cord hood locks and adding a release mechanism that activates based on AEB (Automatic Emergency Braking) results, human safety protection can be achieved, reducing hardware and operating costs and facilitating the widespread application of the technology.

[0037] After introducing the basic principles of this application, various non-limiting embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0038] Exemplary methods

[0039] Figure 1 The diagram shown is a flowchart of an active human body protection method provided in one embodiment of this application. Figure 1 The method described can be executed by a computing device at the vehicle (e.g., body controller (BCM), vehicle control unit (VCU), autonomous driving domain controller, etc.), but the embodiments of this application are not limited thereto.

[0040] like Figure 1 As shown, the method includes the following:

[0041] Step S210: Acquire perception data related to the environment surrounding the target vehicle.

[0042] In this application embodiment, the target vehicle may include various types of motor vehicles, such as cars, SUVs, trucks, etc., but this application embodiment is not limited thereto.

[0043] The perception data includes various information about the environment surrounding the target vehicle, such as the distance, relative speed, and direction between the target vehicle and people, bicycles, electric bicycles, motorcycles, etc. This perception data can be acquired through onboard perception devices located at the target vehicle, which may include ultrasonic radar, lidar, cameras, etc. The perception data can also be obtained through collaborative perception data collected by other vehicles and vehicle-to-infrastructure (V2I) cloud systems based on vehicle-to-everything (V2X) technology. In some cases, the perception data may only include perception data within a preset distance range in front of the target vehicle.

[0044] Step S220: Based on the perceived data, determine whether the front of the target vehicle is about to collide with a human body.

[0045] In this embodiment, the hood refers to a component at the front of the vehicle used to cover the engine compartment. Of course, for some electric vehicles without an engine, the hood may also refer to a component used to cover other equipment or storage space at the front of the vehicle, such as a component used to cover a storage compartment or electrical equipment compartment at the front of an electric vehicle.

[0046] In this embodiment of the application, the collision accident includes collision accidents between the target vehicle and a human body, bicycle, electric bicycle, motorcycle, etc.

[0047] In this embodiment of the application, determining whether the front hood of the target vehicle is about to collide with a human body may include: predicting whether a collision will occur based on the movement state of the target vehicle and the human body, bicycle, electric bicycle, motorcycle, etc.

[0048] In this embodiment of the application, determining whether the hood of the target vehicle is about to collide with a human body may include: determining whether the hood of the target vehicle is about to collide with a human body when the target vehicle's speed is within a preset speed range. The preset speed range can be set according to the situation, for example, 10km / h to 70km / h.

[0049] Step S230: If the front of the target vehicle is about to collide with a human body, the hood lock of the target vehicle is unlocked from the fully locked position to the target position within a first preset time using a reusable release structure; when the hood lock is in the target position, there is a deformation buffer space under the front hood of the target vehicle.

[0050] In this embodiment of the application, the impending collision between the front of the target vehicle and a human body may include an accident that is unavoidable even with emergency braking via the AEB system.

[0051] In this embodiment of the application, the deformation buffer space under the front hood can be used to absorb collision energy and reduce injury to the human body.

[0052] In this embodiment, the hood lock is used to control the opening and closing state of the front hood. The hood lock may have a fully locked position and a target position. The target position may be a partially locked position of the hood lock, or other positions, as long as a deformation buffer space can be formed under the front hood.

[0053] In this embodiment, the release structure can be used to unlock the hood lock of the target vehicle from a fully locked position to a target position within a first preset time when the front of the target vehicle is about to collide with a human body. Specific implementation methods include, but are not limited to, electric release mechanisms, pneumatic release mechanisms, and hydraulic release mechanisms. The release structure unlocks the hood lock from a fully locked position to the target position with minimal damage to the structure and function of the hood lock and does not affect the reusability of the release structure.

[0054] In this embodiment, the first preset time is used to ensure that the hood has popped up and a deformation buffer space has been formed beneath the hood before a possible collision occurs. The first preset time can be set according to actual conditions, for example, 30 milliseconds.

[0055] In this embodiment, by acquiring perception data related to the surrounding environment of the target vehicle, it is determined whether a collision is imminent between the front of the vehicle and a human body. If a collision is imminent, a reusable release structure unlocks the hood lock from the fully locked position to the target position within a preset time, thereby creating a deformation buffer space under the hood and effectively protecting the human body.

[0056] Compared to traditional explosive bolt solutions, this embodiment employs a reusable release structure, which not only enables rapid response upon impact, quickly creating an effective buffer space to mitigate injury, but also allows for easy restoration of the system to its initial state after the impact, without the need to replace critical components. This feature significantly reduces maintenance requirements due to component damage or wear, thereby effectively lowering long-term operating costs.

[0057] Secondly, because this method is inexpensive to use, even if malfunctions occur in certain situations, the impact on the overall system is relatively small. This allows for a reduction in the criteria for judging human collision accidents, and by lowering the action threshold, the reliability of the human protection system can be further improved. Therefore, this system can function effectively in a wider range of scenarios, ensuring human safety without incurring unnecessary high costs due to malfunctions.

[0058] Furthermore, also due to its low cost, this method allows the hood to pop up before the initial impact between the vehicle and a person's legs or torso. This design prevents the moment the person's head collides with the hood from coinciding with the moment the hood begins to pop up, thus further reducing injury. By popping up the hood in advance, additional protection can be provided to the person before a collision occurs, effectively reducing serious injuries caused by the hood popping up too late.

[0059] Finally, the traditional use of expansion bolts was primarily due to the fact that older vehicles lacked AEB (Automatic Emergency Braking) functionality, relying solely on collision sensors to detect a collision before the hood popped open. In such cases, the response time was extremely short, necessitating the use of expansion bolts for rapid response. However, the high cost of existing human safety systems limited their widespread adoption. While modern vehicles now possess AEB functionality, they still utilize the traditional expansion bolt solution. In this embodiment, by simply adding an electric release mechanism to the hood lock, a fast and reusable hood lock can achieve human safety functionality, significantly reducing hardware costs and facilitating the widespread adoption of active human safety technology.

[0060] based on Figure 1 In addition to the method described in the embodiments of this specification, some specific implementation schemes of the method are also provided, which will be described below.

[0061] Optionally, the target position is the half-lock position of the hood lock; when the hood lock is in the half-lock position, the front hood is in a locked state.

[0062] In this embodiment, the hood lock can have a fully locked position and a half-locked position; in some cases, it also has a fully released position. In the half-locked position, the hood cannot be opened directly and is only allowed to pop up a small distance (e.g., 10mm-50mm), thus forming a deformation buffer space under the hood. The hood can only be unlocked and opened by manual operation or further electric operation.

[0063] In this embodiment of the application, the locked state means that the front hood is in a state that cannot be opened directly, and further manual or electric operation is required to unlock and open the front hood.

[0064] In this embodiment, the target vehicle includes a front compartment, which can be covered by a hood. The front compartment can be configured as an engine compartment or a storage compartment, without specific limitations. A hood lock can hold the hood in the position covering the front compartment.

[0065] Specifically, a latch may be provided at the front of the hood, and the hood lock uses the latch to lock the hood. The hood lock may include a main latch and an auxiliary latch. The fully locked position may include the case where both the main latch and the auxiliary latch are locked. The fully released position may include the case where both the main latch and the auxiliary latch are released.

[0066] The semi-locked position can include a situation where the main latch is released but the auxiliary latch is not. In this case, the hood cannot be fully opened, but is only allowed to open a small distance (e.g., 10mm-50mm), which allows a deformation buffer space to be formed under the hood. To fully open the hood, the auxiliary latch must first be released.

[0067] The release structure can at least release the main latch; in some cases, the release structure can also be used to lock the main latch, release the auxiliary latch, and lock at least one of the auxiliary latches. The release structure may include an electric actuator and / or a mechanical actuator, without specific limitations herein.

[0068] In this embodiment, when the front of the target vehicle is about to collide with a human body, the hood lock of the target vehicle is unlocked from the fully locked position to the half-locked position to form a deformation buffer space under the hood. This operation has a dual purpose: on the one hand, it can effectively prevent the hood from popping up too high and affecting the driver's vision, ensuring that the driver can still maintain a good field of vision in an emergency so as to take other necessary avoidance measures in time; on the other hand, it can effectively prevent the front edge of the hood from cutting people due to popping up too high, further improving the safety of the human body.

[0069] Optionally, after unlocking the hood lock of the target vehicle from the fully locked position to the target position within a first preset time period, the method further includes:

[0070] After a second preset time, it is detected whether the target vehicle has collided with a human body;

[0071] If the target vehicle does not collide with a human body, the release structure locks the hood lock of the target vehicle from the target position to the fully locked position.

[0072] In this embodiment, the second preset time is used to detect whether a collision has occurred after a possible collision has taken place. The second preset time can be set according to actual conditions, for example, 30 seconds. Alternatively, the second preset time can be set based on the estimated collision time determined by sensing data.

[0073] In this embodiment of the application, the release structure is also used to lock the hood lock of the target vehicle from the target position to the fully locked position.

[0074] In this embodiment, after confirming that the target vehicle has not collided with a person, the hood lock of the target vehicle is locked from the target position to the fully locked position. This effectively prevents the hood lock from remaining in the target position for an extended period due to misjudgment, preventing the hood from accidentally popping up, affecting the driver's view, or causing other safety hazards, thus ensuring the normal driving and safety of the vehicle. It also simplifies the user's hood reset operation, contributing to improved overall performance and user experience of the active human protection system.

[0075] Optionally, after unlocking the hood lock of the target vehicle from the fully locked position to the target position within a first preset time period, the method further includes:

[0076] Continuously monitor whether the target vehicle has collided with a human body;

[0077] If no collision between the target vehicle and a person is detected within a second preset time after the hood lock is unlocked to the target position, the hood lock of the target vehicle is locked from the target position to the fully locked position by the release structure.

[0078] Optionally, detecting whether the target vehicle has collided with a human body includes:

[0079] Based on whether the collision sensor of the target vehicle emits a collision signal, it can be detected whether the target vehicle has already collided with a human body.

[0080] Figure 2 The diagram illustrates a process flow chart for automatic hood reset according to an embodiment of this application. As shown, if no collision signal is received from the collision sensor within a second preset time after the hood is released to the target position, it is determined that no collision has occurred with the target vehicle, and a locking command is sent to the hood lock. The hood lock automatically engages to the fully locked position in response to the locking command, completely locking the hood.

[0081] In this embodiment, the collision sensor may include: a mechanical collision sensor and an electronic collision sensor; a mechanical collision sensor typically consists of a triggering component and an elastic component. When a vehicle is involved in a collision, the triggering component is displaced under the action of the elastic component, thereby generating a collision signal; an electronic collision sensor includes an acceleration sensor and a pressure sensor, etc. The acceleration sensor determines whether a collision has occurred by detecting changes in the vehicle's acceleration during a collision, while the pressure sensor emits a collision signal by detecting changes in the pressure generated during a vehicle collision.

[0082] In this embodiment of the application, the collision signal is a signal emitted by the collision sensor when a collision is detected. The signal can be an electrical signal, an optical signal, or a mechanical signal, etc., and is used to indicate that a collision has occurred.

[0083] In this embodiment of the application, detecting whether the target vehicle has collided with a human body using a collision sensor helps to accurately determine whether a collision has occurred.

[0084] Optionally, after unlocking the hood lock of the target vehicle from the fully locked position to the target position within a first preset time period, the method further includes:

[0085] Continuously acquire perception data related to the environment surrounding the target vehicle;

[0086] Based on the perceived data, detect whether the target vehicle has collided with a human body;

[0087] If no collision between the target vehicle and a person is detected within a second preset time after the hood lock is unlocked to the target position, the hood lock of the target vehicle is locked from the target position to the fully locked position by the release structure.

[0088] Optionally, detecting whether the target vehicle has collided with a human body includes:

[0089] When the target vehicle is stationary, detect whether the target vehicle has collided with a human body.

[0090] In this embodiment of the application, when the target vehicle is in a stopped state, it is detected whether the target vehicle has collided with a human body; thus, after the target vehicle stops, it is timely and accurate to determine whether a collision has occurred, further improving the reliability and safety of the system.

[0091] Optionally, after unlocking the hood lock of the target vehicle from the fully locked position to the target position within a first preset time period, the method further includes:

[0092] In response to a command from the target user, the hood lock of the target vehicle is locked from the target position to the fully locked position.

[0093] In this embodiment, the target user instruction can be used to instruct the hood lock to move from the target position to the fully locked position. The target user instruction can be received through a human-machine interface, such as a physical button, a virtual button on a touchscreen, or an intelligent voice recognition system or gesture capture device.

[0094] In this embodiment, after the hood lock is unlocked to the target position, the release structure can be used to lock the hood lock to the fully locked position. In the event that the target vehicle has already collided with a person, the release structure can also be used to lock the hood lock to the fully locked position. Of course, situations where the structure is damaged and cannot function properly cannot be excluded.

[0095] In this embodiment, after unlocking the hood lock of the target vehicle from the fully locked position to the target position within a first preset time, the hood lock is then locked from the target position to the fully locked position according to the driver's user instruction. This allows the hood lock to be promptly restored to the fully locked position according to the driver's wishes in the event of no collision or a minor collision, ensuring normal vehicle operation and safety, while also improving system flexibility and user experience.

[0096] Optionally, if the front of the target vehicle is about to collide with a human body, the hood lock of the target vehicle is unlocked from the fully locked position to the target position within a first preset time using a reusable release structure, including:

[0097] If the front of the target vehicle is about to collide with a human body while the target vehicle is traveling at a speed within a preset speed range, a release signal is generated; the release signal is used to instruct the release structure to unlock the hood lock from the fully locked position to the target position.

[0098] In this embodiment of the application, the vehicle-mounted sensing device may include ultrasonic radar, lidar, camera, etc., for acquiring target sensing data within a preset distance range in front of the target vehicle.

[0099] In this embodiment of the application, the target perception data may include information such as the distance, relative speed, and direction between the target vehicle and the human body, bicycle, electric bicycle, etc.

[0100] In this embodiment of the application, the collision accident refers to a collision accident between the target vehicle and a human body, bicycle, electric bicycle, etc.

[0101] In this embodiment of the application, the release signal can be generated by the vehicle's on-board computing device to instruct the release structure to unlock the hood lock from the fully locked position to the target position.

[0102] In practical applications, vehicle speed has a significant impact on the severity of injuries to the human body in collision accidents. When the vehicle speed is low, the relative speed between the vehicle and the human body is small, the collision energy is low, and the injury to the human body is minor. In this case, there is no need to pop up the hood to create a buffer space. However, when the vehicle speed is too high, even if the system issues a command to pop up the hood in time, the popping process takes time, and a collision may have already occurred before the popping action is completed. The popping action of the hood not only fails to reduce the injury, but may also aggravate the injury due to the instability during the popping process.

[0103] In this embodiment, by setting a preset speed range, when the vehicle speed is within this range, the system can trigger the pop-up action of the hood before a collision occurs, ensuring that the hood is already in a pop-up state at the time of the collision, forming an effective deformation buffer space under the hood to reduce injury to the human body. This preset speed range allows the system to work effectively in different speed scenarios, avoiding unnecessary pop-up actions at low speeds and ensuring sufficient time to complete the pop-up action at high speeds, thus providing appropriate protection and improving the system's applicability and flexibility.

[0104] Figure 3 The diagram shows a flowchart of an active human protection method according to an embodiment of this application. As shown, a vehicle speed sensor is used to acquire vehicle speed information and transmit this information to a safety monitoring system. Simultaneously, vehicle-mounted sensing devices such as radar and cameras are used to acquire road condition information ahead of the vehicle, including the distance, relative speed, and direction between the target vehicle and human body, bicycle, electric bicycle, etc., and this information is also transmitted to the safety monitoring system. The safety monitoring system performs comprehensive monitoring and judgment based on the received vehicle speed information and road condition information ahead. When the safety monitoring system determines that a dangerous situation exists, i.e., the front of the target vehicle is about to collide with a human body, it will issue a corresponding signal. On one hand, this signal will be transmitted to the vehicle braking system to trigger the vehicle braking, in order to avoid or mitigate the collision accident as much as possible; on the other hand, this signal will be transmitted to the hood lock unlocking device to trigger the hood lock to unlock, causing the hood lock to unlock from the fully locked position to the half-lock position, thereby causing the hood to pop up a certain height, forming a deformation buffer space under the hood to reduce injury to the human body.

[0105] Optionally, the release structure includes an electrically operated release mechanism.

[0106] In this embodiment, the electrically released mechanism is used to unlock the hood lock of the target vehicle from the fully locked position to the target position in response to an electrically released signal. The electrically released signal can be issued by the vehicle's onboard computing device. When the onboard computing device determines, based on perception data, that the front of the target vehicle is about to collide with a person, it generates an electrically released signal and sends it to the electrically released mechanism. Upon receiving the signal, the electrically released mechanism quickly executes the unlocking action, unlocking the hood lock from the fully locked position to the target position within a first preset time, ensuring a deformation buffer space is formed under the hood to reduce injury to the person.
