Description
Technical Field
The invention relates to the field of intelligent automobiles, in particular to a working method of an engine hood for protecting pedestrians of an intelligent automobile.
Background
The pedestrian accidents are closely related to the traveling of almost everyone and are fatal injuries of the weak people caused by the strong people, so the accident forms become the focus of public opinion attention. Pedestrian injury during a traffic accident is more serious than that of passengers in a vehicle, so that it is very necessary to research measures for protecting pedestrians.
Pedestrian injury in a traffic accident results primarily from a first impact with the vehicle body followed by a second impact with the ground. Generally, the car body impact is the main cause of human body injury, but the damage of human body to the ground is not negligible. At present, researches focus on the protection of damages caused by a vehicle body, and scholars provide a series of methods such as more friendly vehicle head shapes, various safety airbags of the vehicle head, variable engine hoods and the like. And the scheme about human collision damage protection is less, and measures such as a vehicle head safety air bag, a viscous engine hood and the like are provided only in a few results to prevent the human body from falling. The intelligent automobile protection device is related to the low level of the current automobile intelligence, the damage caused by the collision of the automobile body can be prevented under the current technical level, and the ground damage is naturally prevented and placed at a secondary position. However, with the development of intelligent technology, the automobile has the capability of monitoring the motion of the human body and controlling the motion of the vehicle in real time in the future. Therefore, for future intelligent automobiles, the collision and damage of people, vehicles and ground can be protected together.
In a collision accident of a passenger, generally, the lower limbs of a human body are firstly impacted by a front bumper of an automobile, then the buttocks are impacted with the front edge of an engine hood, then the chest, the upper limbs and the head are sequentially impacted with the rear edge of the engine hood or a windshield, and then the human body is considered to have the same initial speed with a vehicle body and be thrown out; if the vehicle keeps braking after the human body is thrown out, people and vehicles can separate, and the pedestrians can fall onto the ground finally to cause the collision damage of people and the ground. It is easy to find that the only parts in contact with the human body in an accident are the front bumper, the engine hood and the windshield, wherein the engine hood is located in the middle of these parts, which can be designed appropriately so that the engine hood can protect both the human-vehicle collision and the human-ground collision.
Disclosure of Invention
Aiming at the fact that most of the existing research results only protect people and vehicles from collision damage, the invention designs the working method of the engine cover for protecting pedestrians and vehicles of the intelligent automobile, and the engine cover can protect people and vehicles and prevent people from collision damage. The engine cover comprises three layers, wherein the lower layer is a supporting layer, the middle layer is an air bag layer, the outer layer is a protective layer, and the air bag layer comprises front, middle and rear 3 hedgehog-shaped air bags. The pedestrian protection method comprises the following steps:
s1: when the automobile detects that the accident is inevitable, the air bag layer is exploded, and the automobile is completely braked until the t1 moment when the head of the human body collides with the automobile body for the first time;
s2: after the time t1, controlling the speed of the vehicle to ensure that the rear edge of the engine hood keeps a certain distance from the human body and moves forwards together with the rear edge of the engine hood;
s3: after the human body is detected to fall onto the engine cover, the vehicle is completely braked again until the vehicle is static.
When the intelligent automobile detects that an accident cannot be avoided, the intelligent automobile starts to completely brake the automobile after the air bag layer is detonated until the moment t1 when the head of a human body collides with the automobile body for the first time, then the speed of the automobile is controlled so that the rear edge of the engine hood of the automobile keeps a certain distance with the human body and moves forwards together with the human body, and then the intelligent automobile completely brakes again until the automobile is static after the human body is detected to fall onto the engine hood. The safety air bag which is expanded after the air bag layer is exploded reduces the collision injury of people and vehicles, meanwhile, the moving vehicles catch the human body to change the falling posture of the human body, and the friction force produced by the expanded air bag slows down the speed of the human body falling to the ground so as to protect the collision injury of the people, vehicles and the ground.
Preferably, the engine cover for protecting pedestrians of the intelligent automobile comprises three layers, wherein the bottom layer is a supporting layer, the middle layer is an air bag layer, and the outer layer is a protective layer. The air bag layer consists of a front hedgehog-shaped safety air bag, a middle hedgehog-shaped safety air bag and a rear hedgehog-shaped safety air bag, and the air bag detonating device is connected with a vehicle central console.
Preferably, the outer layer of the engine hood for protecting pedestrians by the intelligent automobile is made of a composite material plate which is environment corrosion resistant, easy to break under the action of impact force from inside to outside and not easy to break under the action of impact force from outside to inside, and the periphery of the outer layer is fixedly connected with the bottom layer. The outer layer serves to protect the airbag in the middle layer and can ensure that the airbag can be broken under the impact of the airbag after an accident without obstructing the deployment of the airbag.
Preferably, a front airbag in an airbag layer of the engine hood for protecting pedestrians of the intelligent automobile is positioned at the front edge of the engine hood, the tail end of the front airbag is fixedly connected with a bottom supporting layer, and the front airbag sags to pass through a front bumper and touch the ground after being detonated. The height of the unfolded air bag is the same as the front edge of the engine cover, the width of the unfolded air bag is the same as the width of the vehicle body, air columns with barbs are distributed on the surface of the unfolded air bag, and the height of each air column is 0.5 m. The front airbag has 3 functions: firstly, the direct impact force of the vehicle body on the lower limbs of the human body in an accident is reduced; secondly, the air column with the barb blocks the lower limbs of the human body from being thrown out, so that the rotation angular speed of the human body is reduced; and thirdly, the device has certain function of preventing the vehicle from rolling human body.
Preferably, the lower end of an air bag in an air bag layer of the engine hood for protecting pedestrians of the intelligent automobile is fixedly connected with a bottom supporting layer, the ignited air bag covers the whole engine hood, air columns with barbs are distributed on the surface of the air bag, and the height of each air column is 0.5 m. The middle air sac has 4 functions: firstly, the first direct impact force between the human body and the engine hood is reduced; secondly, the speed of the human body thrown out is reduced through the action of the barb air column; thirdly, in the process of catching the human body in the step S3, reducing the secondary impact of the human body and the vehicle and slowing down the speed of the human body falling to the ground; and fourthly, the air column is utilized to provide a hand-grasping object for the human body which is not injured by the fate so as to consume the kinetic energy of the human body and prevent the human body from sliding downwards.
Preferably, a rear airbag in an airbag layer of the engine hood for protecting pedestrians of the intelligent automobile is located at the rear edge of the engine hood, the tail end of the rear airbag is fixedly connected with a bottom supporting layer, and the rear airbag extends upwards to the middle of the windshield along the front windshield after being detonated. The width of the unfolded air bag is the same as that of the vehicle body, an air column with barbs is distributed on the surface of the air bag, and the height of the air column is 0.5 m. The effects are three: firstly, the direct collision force between a human body and the windshield is reduced; secondly, the human body is prevented from being thrown out so as to reduce the throwing speed of the human body; and thirdly, the secondary impact is reduced and the speed of the human body sliding to the ground is reduced in the process of receiving the person.
Preferably, the supporting layer of the engine cover for protecting pedestrians of the intelligent automobile is made of composite material plates meeting the design requirements of rigidity and strength. The function of the engine hood is to fix the air bag layer and bear certain human impact force so as to ensure that the engine hood can normally perform the function under the impact of the human body.
Preferably, in the pedestrian protection step of the engine hood for protecting the pedestrian by the intelligent automobile, the time t1 in the step S1 is the time of the first impact between the head of the human body and the automobile body; in the individual cases, the head and the vehicle body do not directly collide with each other, and t1 represents the time when the entire human body is thrown. Fully braking the vehicle before this time is to reduce the collision speed between the human and the vehicle as much as possible.
Preferably, in the pedestrian protection step of the hood for protecting pedestrians by the intelligent automobile, the distance d between the rear edge of the hood and the human body in the step S2 is the distance from the rear edge of the hood to the chest of the human body in the horizontal direction, and is a decreasing variable, and the value of the decreasing variable is determined according to the distance d0 from the chest of the human body to the rear edge of the hood in the horizontal direction monitored in each step
d-d 0-0.1 m
And taking zero when the value d calculated by the above formula is less than or equal to zero. The distance between the human body and the rear edge of the engine hood is determined in such a way that the vehicle speed is gradually changed, so that the rear edge of the engine hood gradually approaches to the human body without rapidly changing the vehicle speed, and more importantly, the action of accelerating the automobile is prevented when the chest position of the human body cannot reach the rear edge position of the engine hood under low-speed collision.
Preferably, in the pedestrian protection step of the engine hood for protecting pedestrians by the intelligent automobile, the vehicle speed in the step S2 is controlled by:
assuming that the distance between the rear edge of the engine hood and the chest position of the human body at a certain moment in the horizontal direction is d0, the vehicle detects that the running speed of the chest of the human body in the horizontal direction is v20, and the distance is required to be adjusted to d within a step delta t time, the running speed v of the vehicle within the delta t time is
Preferably, in the pedestrian protection step of the engine hood for protecting pedestrians by the intelligent automobile, the step of detecting that the human body falls to the engine hood in the step of S3 means that the chest of the human body is in contact with the engine hood after the step of S1. By using the chest as the determination index, it is possible to further avoid accelerating the vehicle, increasing the kinetic energy of the human body, and thus increasing the human-ground collision speed in order to achieve the constraint condition of the distance d in step S2 in the event of a low-speed collision. Under the low-speed impact, when the distance between the rear edge of the engine hood and the chest of the human body is larger than d, the chest of the human body is in contact with the engine hood again, the step S2 does not need to be continued, the step S3 can be directly started, and further the situation that the human body obtains more kinetic energy from the vehicle body due to the fact that the vehicle is accelerated is avoided. Catching the fallen human body with the hood through step S3 may advantageously reduce human impact for three reasons: firstly, the speeds of the people and the vehicle in the horizontal direction are close to the same at t1, so that the impact force on the human body in the horizontal direction is not large in the catching process, secondly, the falling height of the human body is reduced, the vehicle body can absorb a large part of gravitational potential energy which is absorbed by the ground, and thirdly, the vehicle head is covered with an air bag to absorb the total falling energy of the human body.
Compared with the prior art, the technical scheme of the invention has the beneficial effects that: the air bag layer of the engine cover is detonated, so that the head of the vehicle covers the hedgehog-shaped safety air bag, the direct collision force between a person and a vehicle is reduced, meanwhile, the speed of throwing out the pedestrian is delayed by the inverted hook-shaped air column outside the air bag, the collision of the person and the vehicle is directly protected, and meanwhile, the kinetic energy obtained by the human body from the vehicle body is consumed; and then the vehicle is moved to enable the vehicle head to catch the human body, and the air columns on the outer surfaces of the air bags delay the falling speed of the human body so as to further consume the potential energy and the kinetic energy of the human body, further reduce the collision speed of people and the ground, and accordingly realize the simultaneous protection of the collision of people, vehicles and the ground.
