Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to a method, device, equipment, and program product for pedestrian protection in the event of a vehicle collision. Background Technology

[0002] Collisions during vehicle operation can cause serious leg injuries to pedestrians, especially since the presence of crash beams can directly lead to knee bending after a collision. Some existing solutions involve adding a shin guard beam with the same lateral dimensions as the main crash beam, aiming to impact the pedestrian's lower leg and knee simultaneously, preventing the lower leg from being trapped under the vehicle and reducing stress on the knee. However, shin guard beams are generally less rigid than the main crash beam, and their compression cannot be synchronized, still resulting in knee bending. Even if the shin guard beam has the same rigidity as the main crash beam, preventing the lower leg from bending, the thigh can still bend towards the hood, causing knee injury. Increasing the strength of the front of the hood to distribute the force evenly across the thigh can reduce knee impact by distributing the force across the entire leg, but this can lead to excessive stress on the hip or lower back, causing injury.

[0003] In summary, there is an urgent need for a solution that can prevent excessive stress on the waist and hip area of ​​pedestrians during vehicle collisions and can also protect the legs of pedestrians. Summary of the Invention

When a pedestrian collision is detected and the vehicle speed is high, the method controls the lower leg protection beam to push forward and the upper crossbeam of the water tank frame to collapse downward, causing the body of the pedestrian to tilt towards the engine hood. On the one hand, this can make the force on the pedestrian's legs more even, reducing the impact on the knees. On the other hand, since the pedestrian's legs and upper body tilt towards the engine hood together, it can avoid excessive force on the hip or waist due to inertia, thus achieving buffer protection for the pedestrian's legs and upper body and reducing the degree of injury to the pedestrian under vehicle collision.

[0006] Another objective of this invention is to provide a pedestrian protection device in the event of a vehicle collision.

[0010] Furthermore, in one embodiment of the present invention, the collapse structure is an active collapse structure, wherein controlling the forward thrust of the lower leg protection beam and the downward collapse of the upper crossbeam of the water tank frame specifically includes: The first control signal controls the extension of the lifting structure, causing the lower leg protection beam to be pushed forward; The active collapse structure is shortened by controlling the second control signal, causing the upper crossbeam of the water tank frame to collapse downwards.

[0011] Furthermore, in one embodiment of the present invention, the collapse structure is a passive collapse structure, wherein controlling the forward thrust of the lower leg protection beam and the downward collapse of the upper crossbeam of the water tank frame specifically includes: The first control signal controls the extension of the lifting structure, causing the lower leg protection beam to be pushed forward; When the upper crossbeam of the water tank frame is squeezed by a pedestrian who has collided with it, the passive collapse structure shortens under the pressure, causing the upper crossbeam of the water tank frame to collapse downwards.

[0012] On the other hand, embodiments of the present invention provide a pedestrian protection device under vehicle collision, applied to a vehicle, the vehicle including a front bumper beam, a lower leg protection beam, and a radiator frame installed in the engine compartment, the pedestrian protection device including: The judgment module is used to determine whether a pedestrian collision has occurred when the vehicle's collision sensor is triggered, and to determine whether the vehicle's speed is greater than a preset first threshold. The control module is used to control the lower leg protection beam to push forward and the upper crossbeam of the water tank frame to collapse downward when the vehicle collides with a pedestrian and the vehicle speed is greater than the first threshold, so that the body of the pedestrian being collided with tilts towards the engine hood.

[0013] Furthermore, in one embodiment of the present invention, the two ends of the upper crossbeam of the water tank frame are respectively connected to the top of the two side longitudinal beams of the water tank frame through two collapsible structures, the two ends of the anti-collision beam are respectively fixedly connected to the middle of the two side longitudinal beams of the water tank frame through two front longitudinal beams, and the two ends of the lower leg protection beam are respectively connected to the bottom of the two side longitudinal beams or the two ends of the lower crossbeam of the water tank frame through two lifting structures.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In the following description, when referring to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the embodiments of this invention; they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of this invention as detailed in the appended claims.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing embodiments of the invention only and is not intended to limit the invention.

[0023] Reference Figure 1 This invention provides a pedestrian protection method under vehicle collision, applied to a vehicle, which includes a front bumper beam, a lower leg protection beam, and a radiator frame in the engine compartment. The pedestrian protection method includes the following steps: S101. When the vehicle's collision sensor is triggered, determine whether a pedestrian collision has occurred and whether the vehicle's speed is greater than a preset first threshold. S102. When a vehicle collides with a pedestrian and the vehicle speed exceeds the first threshold, the lower leg protection beam is pushed forward and the upper crossbeam of the water tank frame is collapsed downward, causing the body of the pedestrian to tilt towards the engine hood.

[0024] like Figure 3 This is a schematic diagram of the principle of a pedestrian protection method under vehicle collision provided by an embodiment of the present invention. As can be seen, when a pedestrian collision is detected and the vehicle speed is high, the position of the anti-collision beam 1 in this embodiment of the present invention remains unchanged, the lower leg protection beam 2 is pushed forward and the upper crossbeam 31 of the water tank frame 3 collapses downward, so that the body of the pedestrian being collided tilts towards the engine hood, thereby keeping the force points of the pedestrian's thighs, knees and lower legs roughly in a straight line, and the force is more evenly distributed. The tilting of the legs and upper body together avoids the waist and hip parts from being subjected to excessive force due to the inertia of the upper body.

[0025] As a further optional implementation, the following steps are used to determine whether a pedestrian collision has occurred: S201. In response to the collision signal from the collision sensor, acquire image information of the object colliding in front of the vehicle; S202. Identify whether the object of the collision is a human body based on the image information of the object. If so, determine that the vehicle has collided with a pedestrian.

[0026] Specifically, collision detection is performed by collision sensors installed in the vehicle. When the collision sensor emits a collision signal, the vehicle camera acquires image information of the object in front of the vehicle. Then, based on the image information of the object, it is identified whether the object is a human body. If the object is a human body, it can be determined that the vehicle has collided with a pedestrian.

[0027] The collision sensor can be installed at the front of the vehicle, for example, on the anti-collision beam, but this embodiment of the invention does not limit this.

[0028] When a vehicle collides with a pedestrian and the vehicle's speed exceeds a first threshold, this embodiment of the invention will activate collision protection for the pedestrian. The first threshold is set to avoid false triggering when the vehicle is stationary and collides with a pedestrian while the vehicle is crawling. In both of these scenarios, the impact force on the pedestrian is not significant, and activating collision protection would instead cause the pedestrian to lose balance. In some optional embodiments, the first threshold can be set to 3 km / h.

[0029] Reference Figure 2 and Figure 3 As an optional implementation, the two ends of the upper crossbeam 31 of the water tank frame 3 are respectively connected to the top of the two side longitudinal beams 32 of the water tank frame 3 through two collapsible structures 34, the two ends of the anti-collision beam 1 are respectively fixedly connected to the middle of the two side longitudinal beams 32 of the water tank frame 3 through two front longitudinal beams 4, and the two ends of the lower leg protection beam 2 are respectively connected to the bottom of the two side longitudinal beams 32 or the two ends of the lower crossbeam 33 of the water tank frame 3 through two lifting structures 35.

[0030] Specifically, in this embodiment of the invention, the water tank frame 3 is a longitudinally arranged rectangular frame. The anti-collision beam 1 is fixed in the middle of the water tank frame 3, and the lower leg protection beam 2 is connected to the bottom of the water tank frame 3 through the lifting structure 35. The top of the water tank frame 3 is an upper crossbeam 31 connected by a collapse structure 34. When a vehicle collides with a pedestrian and the vehicle speed is greater than a first threshold, the lifting structure 35 extends, causing the lower leg protection beam 2 to push forward, and the collapse structure 34 shortens, causing the upper crossbeam 31 to collapse downward. Finally, the lower leg protection beam 2, the anti-collision beam 1, and the upper crossbeam 31 are maintained in a plane.

[0031] It is understood that the lifting structure in this embodiment of the invention is an active lifting structure, which can be a blasting lifting structure or an electrically controlled lifting structure. The blasting lifting structure can use a detonator or a gas generator to generate a huge thrust in an instant to push the connecting rod body, thereby pushing the lower leg protection beam forward. The electrically controlled lifting structure can achieve extension and retraction through a motor-driven screw structure, or it can use a motor to drive a hydraulic pump to generate pressure to push the hydraulic cylinder to extend and retract. The embodiments of the invention will not be listed one by one here.

[0032] As a further optional implementation, the collapse structure is an active collapse structure, which controls the forward thrust of the lower leg protection beam and the downward collapse of the upper crossbeam of the water tank frame, specifically including: S301. The first control signal controls the extension of the lifting structure, causing the lower leg protection beam to be pushed forward. S302. The active collapse structure is shortened by controlling the second control signal, so that the upper crossbeam of the water tank frame collapses downward.

[0033] Specifically, the collapse structure in this embodiment of the invention can be an active collapse structure, such as a burst-type collapse structure or an electrically controlled drive-type collapse structure. The burst-type collapse structure can use a reverse detonator to trigger directional blasting, instantly cutting off or weakening the support structure to achieve the collapse and sinking of the upper crossbeam. Alternatively, a gas generator can generate high-pressure gas to push the linkage mechanism to break or displace, thereby achieving the collapse and sinking of the upper crossbeam. The electrically controlled drive-type collapse structure can achieve active collapse through a motor-driven lead screw structure, or it can use an electromagnetic unlocking collapse structure, that is, the upper crossbeam is normally fixed by an electromagnetic lock, and the electromagnetic lock is de-energized and unlocked during a collision, and the upper crossbeam collapses by relying on springs or gravity.

[0034] In some optional embodiments, when an active collapse structure is used, the elongation distance of the lifting structure and the shortening distance of the active collapse structure can be controlled by the first control signal and the second control signal, respectively, so that the lower leg protection beam, the anti-collision beam and the upper crossbeam are kept in one plane.

[0035] As a further optional implementation, the collapse structure is a passive collapse structure, which controls the forward thrust of the lower leg protection beam and the downward collapse of the upper crossbeam of the water tank frame, specifically including: S303. The first control signal controls the extension of the lifting structure, causing the lower leg protection beam to be pushed forward. S304. When the upper crossbeam of the water tank frame is squeezed by a pedestrian who has collided with it, the passive collapse structure shortens under the action of the compressive force, causing the upper crossbeam of the water tank frame to collapse downward.

[0036] Specifically, the collapse structure in this embodiment of the invention can also be a passive collapse structure, such as a pre-set collapse guide groove, that is, a groove or weakening line is designed on the side longitudinal beam. When the upper crossbeam of the water tank frame is squeezed by a pedestrian who has been hit, the side longitudinal beam will bend and collapse along the pre-set trajectory, causing the upper crossbeam to collapse downward. Another example is a crushable connector, that is, bolts or rivets of a specific strength are used to connect the upper crossbeam and the side longitudinal beam. When the upper crossbeam of the water tank frame is squeezed by a pedestrian who has been hit, the connector is crushed, causing the upper crossbeam to collapse downward. Another example is a folding structure design, that is, the folding and collapse of the connection area between the upper crossbeam and the side longitudinal beam is achieved through hinges or pivots. The method steps of the embodiments of the present invention have been described above. It can be understood that when the vehicle collision with a pedestrian is detected and the vehicle speed is high, the embodiments of the present invention control the lower leg protection beam to push forward and the upper crossbeam of the water tank frame to collapse downward, so that the body of the pedestrian being hit tilts towards the engine hood. On the one hand, this can make the force on the legs of the pedestrian being hit evenly to reduce the impact on the knees. On the other hand, since the legs and upper body of the pedestrian being hit tilt towards the engine hood together, it can avoid excessive force on the hip or waist due to inertia, thus avoiding excessive damage. This achieves buffer protection for the pedestrian's legs and upper body, reducing the degree of injury to the pedestrian in a vehicle collision.

The vehicle includes a front bumper beam, a lower leg protection beam, and a radiator frame located in the engine compartment. The pedestrian protection device includes: The judgment module is used to determine whether a pedestrian collision has occurred and whether the vehicle speed is greater than a preset first threshold when the vehicle's collision sensor is triggered.

[0038] As a further optional implementation, the two ends of the upper crossbeam of the water tank frame are respectively connected to the top of the two side longitudinal beams of the water tank frame through two collapsible structures, the two ends of the anti-collision beam are respectively fixedly connected to the middle of the two side longitudinal beams of the water tank frame through two front longitudinal beams, and the two ends of the lower leg protection beam are respectively connected to the bottom of the two side longitudinal beams or the two ends of the lower crossbeam of the water tank frame through two lifting structures.
