[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work 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 front hood hinges have some significant defects. First, such systems usually use explosive bolts as unlocking mechanisms. Explosive bolts generate a lot of heat and gas during operation, quickly generating strong pressure, causing the bolts to break or separate in a very short time. As a disposable component, the explosive bolts need to be replaced after each triggering, which greatly increases the cost of active human protection and limits the reusability of the system.

[0033] Secondly, the system has extremely high requirements for the judgment of collision accidents, and must rely on high-precision sensors and complex control algorithms to ensure that the protection mechanism is accurately triggered at the right 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] In addition, in order to avoid misoperation as much as possible, the current human protection strategy is to make the hood pop up only after a collision occurs. In actual applications, due to the overlap in time, the moment when the human head collides with the hood may coincide with the moment when the hood begins to pop up, which means that the hood has come into contact with the human head before it is fully popped up, which may cause additional impact on the human head and further aggravate the injury.

[0035] In order to solve the above problems, an improved active human protection method is proposed in the embodiment of the present application. By acquiring the perception data related to the surrounding environment of the target vehicle, it is judged whether the front of the vehicle is about to collide with the human body. If a collision is about to occur, the hood lock is unlocked from the fully locked position to the half-locked position within a preset time through a reusable release structure. When the hood lock is in the half-locked position, the front hood cannot be opened directly, and there is a deformation buffer space under the front hood, thereby effectively protecting the human body.

[0036] Compared with the traditional explosive bolt solution, this method not only reduces maintenance costs, but also allows the system's response speed and accuracy to be improved by lowering the action threshold, avoiding the risk of additional injuries caused by the delay in the hood pop-up. In addition, by improving the existing manual pull-wire hood lock and setting a release mechanism that can act according to the AEB judgment result, the human body protection function can be realized, reducing hardware costs and usage costs, which is conducive to the popularization and application of technology.

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

[0038] Exemplary Methods

[0039] Figure 1 The figure is a schematic flow chart of an active human body protection method provided by an embodiment of the present application. Figure 1 The method described may be executed by a computing device at the vehicle (e.g., a body controller (BCM), a vehicle control unit (VCU), an autonomous driving domain controller, etc.), but the embodiments of the present application are not limited thereto.

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

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

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

[0043] The perception data includes various information about the target vehicle's surroundings, such as the distance, relative speed, direction, etc. between the target vehicle and a human body, bicycle, electric bicycle, motorcycle, etc. The perception data can be obtained through the on-board perception device at the target vehicle, and the on-board perception device may include ultrasonic radar, laser radar, camera, etc. The perception data can also be obtained based on the Internet of Vehicles technology to obtain collaborative perception data collected by other vehicles and vehicle-road-cloud systems. 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: Determine, based on the perception data, whether the front of the target vehicle is about to collide with a human body.

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

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

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

[0048] In the embodiment of the present application, the determining whether the front hood of the target vehicle is about to collide with a human body may include: determining whether the front hood of the target vehicle is about to collide with a human body when the target vehicle is traveling at a speed within a preset speed range. The preset speed range may be set according to the situation, for example, 10 km / h to 70 km / 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 through a reusable release structure; when the hood lock is in the target position, a deformation buffer space is provided under the front hood of the target vehicle.

[0050] In the embodiment of the present application, the accident in which the front of the target vehicle is about to collide with a human body may include an accident that is unavoidable even through emergency braking by the AEB system.

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

[0052] In the embodiment of the present application, 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 half-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 the embodiment of the present application, the release structure can be used to unlock the hood lock of the target vehicle from the fully locked position to the 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, hydraulic release mechanisms, etc. The release structure unlocks the hood lock from the fully locked position to the target position, causing little damage to the structure and function of the hood lock, and does not affect the reuse of the release structure.

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

[0055] In the embodiment of the present application, by acquiring the sensing data related to the surrounding environment of the target vehicle, it is determined whether the front of the vehicle is about to collide with the human body. If a collision is about to occur, the hood lock is unlocked from the fully locked position to the target position within a preset time through a reusable release structure to form a deformation buffer space under the front hood, thereby effectively protecting the human body.

[0056] Compared with the traditional explosive bolt solution, the embodiment of the present application adopts a reusable release structure, which can not only achieve a quick response when a collision occurs and form an effective buffer space in time, thereby effectively reducing the harm to the human body, but also can easily restore the system to its initial state after the collision, without replacing key components. This feature significantly reduces the need for maintenance due to component damage or wear, thereby effectively reducing the long-term use cost.

[0057] Secondly, since this method is low-cost to use, even if misoperation occurs in certain situations, the impact on the overall system is relatively small. This allows the requirements for the judgment criteria for human collision accidents to be appropriately lowered, and by lowering the action threshold, the reliability of the human protection system can be further improved. Therefore, the system can function in a wider range of scenarios, effectively protecting human safety, and will not lead to unnecessary high costs due to misoperation.

[0058] Furthermore, also because this method is low in cost, it allows the front hood to be popped up in advance before the first collision between the vehicle and the legs or torso of the person. This design avoids the possibility that the moment when the person's head collides with the hood coincides with the moment when the hood starts to pop up, thereby further reducing the damage to the person. By popping up the front hood in advance, additional protection can be provided to the person before a collision occurs, effectively reducing serious injuries caused by the front hood popping up too late.

[0059] Finally, the main reason why explosive bolts are traditionally used is that the original vehicles do not have the AEB (automatic emergency braking) function, and can only rely on the collision sensor to detect the collision before popping up the front hood. In this case, the action time requirement is extremely short, so explosive bolts must be used to achieve a quick response. However, the original human protection system cannot be widely popularized due to its extremely high cost of use. With the continuous development of science and technology, although current vehicles already have the AEB function, the original explosive bolt solution is still used. In the embodiment of the present application, it is only necessary to add a fast and reusable hood lock such as an electric release mechanism to the hood lock to achieve the human protection function, which significantly reduces the hardware cost and is conducive to the popularization and promotion of active human protection technology.

[0060] based on Figure 1 The method in this specification also provides some specific implementation plans of the method, which are described below.

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

[0062] In the embodiment of the present application, the hood lock may have a fully locked position and a half-locked position; in some cases, it may also have a fully released position. In the half-locked position, the front hood cannot be opened directly and is only allowed to bounce up a small distance (e.g., 10 mm-50 mm), thereby forming a deformation buffer space under the front hood, and manual operation or further electric operation is required to unlock and open the front hood.

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

[0064] In the embodiment of the present application, the target vehicle includes a front cabin, and the front cabin can be covered by a front hood. The front cabin can be set as an engine compartment or a storage compartment, which is not specifically limited here. The hood lock can keep the front hood in a position covering the front cabin.

[0065] Specifically, a lock catch may be provided in front of the front hood, and the hood lock locks the front hood through the lock catch. The hood lock may include a main latch and an auxiliary latch. The fully locked position may include a situation where both the main latch and the auxiliary latch are locked. The fully released position may include a situation where both the main latch and the auxiliary latch are released.

[0066] The half-locked position may include a situation where the main latch is released but the auxiliary latch is not released, in which case the front cover cannot be fully opened, and is only allowed to open a small distance (e.g., 10 mm-50 mm) to form a deformation buffer space under the front cover. If the front cover is to be fully opened, the auxiliary latch must be released first.

[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 the auxiliary latch. The release structure can include an electric actuator and / or a mechanical actuator, which is not specifically limited here.

[0068] In an embodiment of the present application, 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 a fully locked position to a half-locked position to form a deformation buffer space under the front 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 line of sight, ensuring that the driver can still maintain a good field of vision in an emergency so that other necessary risk avoidance measures can be taken in time; on the other hand, it can effectively prevent the front edge of the front hood from cutting people due to the front hood 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 the first preset time, the method further includes:

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

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

[0072] In an embodiment of the present application, the second preset time is used to detect whether a collision accident has occurred after a possible collision accident has occurred. The second preset time can be set according to actual conditions, for example, 30 seconds. The second preset time can also be set according to the estimated collision time determined by the perception data.

[0073] In the embodiment of the present 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 the embodiment of the present application, when it is confirmed that the target vehicle has not collided with a human body, the hood lock of the target vehicle is locked from the target position to the fully locked position; thereby effectively avoiding the hood lock being in the target position for a long time due to misjudgment, preventing the front hood from accidentally popping up, affecting the driver's line of sight or causing other safety hazards, and ensuring the normal driving and safety of the vehicle. At the same time, it also simplifies the user's reset operation of the front hood, which helps to improve the 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 the first preset time, the method further includes:

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

[0077] If no collision between the target vehicle and a human body 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, the detecting whether the target vehicle has collided with a human body includes:

[0079] According to whether the collision sensor of the target vehicle sends out a collision signal, it is detected whether the target vehicle has collided with a human body.

[0080] Figure 2 The figure shows a schematic diagram of the process of automatic resetting of the front hood provided by an embodiment of the present application. As shown in the figure, if the collision signal sent by the collision sensor is not received within the second preset time after the front hood is released to the target position, it is determined that the target vehicle has not encountered a collision accident, and a locking command is sent to the hood lock. In response to the locking command, the hood lock automatically closes to the fully locked position, completely locking the front hood.

[0081] In an embodiment of the present application, the collision sensor may include: a mechanical collision sensor and an electronic collision sensor; the mechanical collision sensor is usually composed of a trigger component and an elastic component. When the vehicle is subjected to a collision, the trigger component is displaced under the action of the elastic component, thereby generating a collision signal; the electronic collision sensor includes an acceleration sensor and a pressure sensor, etc. The acceleration sensor determines whether a collision occurs by detecting the acceleration change of the vehicle during a collision, and the pressure sensor sends a collision signal by detecting the pressure change generated when the vehicle collides.

[0082] In the embodiment of the present application, the collision signal is a signal sent by the collision sensor when a collision is detected. The signal may be an electrical signal, an optical signal, or a mechanical signal, etc., and is used to indicate that a collision accident has occurred in the vehicle.

[0083] In the embodiment of the present application, detecting whether the target vehicle has collided with a human body according to 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 the first preset time, the method further includes:

[0085] Continuously acquire perception data related to the target vehicle's surroundings;

[0086] Detecting, based on the sensing data, whether a collision accident occurs between the target vehicle and a human body;

[0087] If no collision between the target vehicle and a human body 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, the detecting whether the target vehicle has collided with a human body includes:

[0089] When the target vehicle is in a stopped state, it is detected whether the target vehicle has collided with a human body.

[0090] In an embodiment of the present application, when the target vehicle is in a stopped state, it is detected whether the target vehicle has collided with a human body; thereby, it is timely and accurately determined whether a collision has occurred after the target vehicle stops, 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 the first preset time, the method further includes:

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

[0093] In an embodiment of the present application, the target user instruction can be used to instruct the hood lock to lock from the target position to the fully locked position. The target user instruction can be received through a human-computer interaction interface, such as a physical button, a virtual button on a touch screen, or an intelligent voice recognition system, a gesture motion capture device, etc.

[0094] In the embodiment of the present application, 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 collided with a human body, the release structure can also be used to lock the hood lock to the fully locked position. Of course, the situation where the hood lock cannot operate normally due to structural damage is not excluded.

[0095] In the embodiment of the present application, after the hood lock of the target vehicle is unlocked from the fully locked position to the target position within the first preset time, the hood lock of the target vehicle is locked from the target position to the fully locked position according to the target user instruction of the driver. Therefore, when there is no collision accident or a minor collision accident occurs, the hood lock can be restored to the fully locked position in time according to the driver's wishes, ensuring the normal driving and safety of the vehicle, and also helping to improve the flexibility of the system 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 by a reusable release structure, including:

[0097] When the driving speed of the target vehicle is within a preset speed range, if the front of the target vehicle is about to collide with a human body, 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 an embodiment of the present application, the vehicle-mounted sensing device may include an ultrasonic radar, a lidar, a camera, etc., which is used to obtain target perception data within a preset distance range in front of the target vehicle.

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

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

[0101] In the embodiment of the present application, the release signal may be generated by an onboard computing device of the vehicle, and is used to instruct the release structure to unlock the hood lock from the fully locked position to the target position.

[0102] In actual applications, the speed of a vehicle has a significant impact on the degree of injury to the human body in a collision accident. When the vehicle is traveling at a low speed, the relative speed when the vehicle collides with the human body is small, the collision energy is low, and the injury to the human body is light. At this time, there is no need to pop up the front hood to form a buffer space. However, when the vehicle is traveling at a high speed, even if the system issues a command to pop up the front hood in time, the pop-up process takes time, and a collision may occur before the pop-up action is completed. The pop-up action of the front hood not only fails to reduce the injury, but may also aggravate the injury due to unstable factors in the pop-up process.

[0103] In the embodiment of the present application, by setting a preset speed range, when the vehicle speed is within this range, the system can trigger the action of popping up the front hood in time before a collision occurs, so that the front hood is already in a pop-up state when a collision occurs, and an effective deformation buffer space is formed under the front hood to reduce damage to the human body. The setting of this preset speed range enables the system to work effectively in different speed scenarios, avoid unnecessary pop-up actions at low speeds, ensure that there is enough time to complete the pop-up action at high speeds, play a suitable protection effect, and improve the applicability and flexibility of the system.

[0104] Figure 3 The flowchart of the active human protection method provided by an embodiment of the present application is shown. As shown in the figure, the vehicle speed sensor is used to obtain the vehicle's driving speed information and transmit the information to the safety monitoring system. At the same time, the vehicle-mounted sensing equipment such as radar and camera is used to obtain the road condition information in front of the vehicle, including the distance, relative speed, direction, etc. between the target vehicle and the human body, bicycle, electric bicycle, etc., and transmits this information to the safety monitoring system. The safety monitoring system performs comprehensive monitoring and judgment based on the received vehicle speed information and the road condition information in front. When the safety monitoring system determines that there is a dangerous situation, that is, the front of the target vehicle is about to collide with the human body, it will send a corresponding signal. On the one hand, the signal will be transmitted to the vehicle braking system to trigger the vehicle braking to avoid or reduce the occurrence of the collision accident as much as possible; on the other hand, the signal will be transmitted to the motor cover lock unlocking device to trigger the motor cover lock unlocking, so that the cover lock is unlocked from the fully locked position to the half-locked position, so that the front cover pops up to a certain height, and a deformation buffer space is formed under the front cover to reduce the damage to the human body.

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

[0106] In an embodiment of the present application, the electric release 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 electric release signal. The electric release signal can be issued by an on-board computing device of the vehicle. When the on-board computing device determines, based on the perception data, that the front of the target vehicle is about to collide with a human body, the on-board computing device generates an electric release signal and sends it to the electric release mechanism. After receiving the signal, the electric release mechanism quickly performs an unlocking action, unlocking the hood lock from the fully locked position to the target position within a first preset time, ensuring that a deformation buffer space is formed under the front hood to reduce damage to the human body.
