Once collision happens, the vehicle body is damaged by scratching the vehicle skin if the collision happens, and the life safety of a driver is threatened if the collision happens. Therefore, our prevention of vehicle collision is not negligible.
Today's inventions on collision avoidance of vehicles are not numerous and most rely on special tools to detect the distance between a vehicle and other vehicles or obstacles to alert the driver to prevent a collision. The distance measuring module and the fog penetrating camera are used as mentioned in patent CN208198262U, so that the distance between the vehicle and the obstacle can be accurately detected in low visibility; the patent CN107444256A measures the relative distance and collects the video data through the distance measuring radar transceiver module and the automobile tail camera; patent CN214985317U and patent CN107487257U are similar to the methods adopted in the above two patents, and both measure the relative distance between the vehicle and the obstacle.
The above inventions can solve some problems, but cannot radically cure the problems. Since in any case the possibility of a vehicle collision, such as a sluggish response of the driver, or a failure of the vehicle brake system, an excessively long braking distance, etc., cannot be ruled out. Therefore, the problem can be solved by preventing the collision of the outer airbag to prevent the vehicle from being damaged even if the vehicle collides. Of course, there are some of the prior patents which are anti-collision by means of an outer airbag, such as patent CN201021237Y which is similar to patent CN107627993A in that a collision is attenuated by an airbag on the front bumper.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further 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.
Specific implementations of the present invention are described in detail below with reference to specific embodiments.
In one embodiment, an automobile omnibearing anti-collision outer airbag system, see fig. 1 to 4, comprises an outer airbag body, an airbag internal sensing system, an air pump, a control unit, a human instruction input port, a vehicle driving assistance system information transmission port and the like.
Further, referring to fig. 1 to 4, the outer airbag body includes a front outer airbag body, a left outer airbag body, a right outer airbag body, and a rear outer airbag body, the front outer airbag body is used for wrapping the front bumper, the rear outer airbag body is used for wrapping the rear bumper, and the left outer airbag body and the right outer airbag body are used for wrapping the body portion between the front wheel and the rear wheel.
Further, referring to fig. 1 to 4, the sensing system inside the airbag can comprehensively monitor parameters such as pressure and temperature inside the airbag. The air bag internal sensing system is connected with the control unit and used for protecting the air bag when the air pump is started to inflate the air bag, the control unit controls the air pump to work according to the received instruction information, and the air pump specifically adopts two working modes of inflation and air exhaust.
Further, referring to fig. 1 to 4, the air pump is connected to the outer airbag body through rubber, a sensing system inside the airbag senses pressure changes and feeds back the pressure changes to the control unit, and the control unit transmits warning information to a driver to remind the driver that the outer airbag has collided.
Further, referring to fig. 1 to 4, the driving assistance system performs a comprehensive decision by combining information such as a real-time vehicle speed and a radar detection obstacle distance, and transmits decision result information to a control unit of the external airbag system of the vehicle.
Further, referring to fig. 1 to 4, the sensing system inside the airbag senses pressure changes, and cooperates with the control unit and the air pump to monitor and adjust the gas state inside the airbag body in real time.
Further, referring to fig. 1 to 4, after the control unit receives the instruction information for closing the system, the control unit controls the air pump to start pumping air. The outer airbag body is vacuumized through a negative feedback regulation model established between the airbag air pump sensing system and the control unit so as to ensure that the outer airbag body is tightly attached to the surface of the vehicle body.
In this embodiment, the on or off is realized by receiving an instruction manually issued by a driver or information transmitted by a vehicle driving assistance system, that is, the manual control operation path and the automatic control operation path are in a parallel relationship.
In the manual control operation path, a manual instruction is mainly controlled and operated through an automobile center console, and the instruction is transmitted to a control unit; in an automatic control running path, an auxiliary driving system carries out comprehensive decision by combining information such as real-time vehicle speed, radar detection barrier distance and the like, and transmits decision result information to a control unit of an automobile outer airbag system.
The control unit controls the air pump to work according to the received instruction information, and the air pump works specifically in two working modes of inflation and air exhaust.
When the air pump inflates the four outer air bag bodies as required, the sensing system in the air bag can comprehensively monitor the parameters of pressure, temperature and the like in the air bag. And the sensing system in the air bag is connected with the control unit and used for protecting the air bag when the air pump is started to inflate the air bag, so that the air bag is prevented from being damaged due to the fact that the inflation exceeds the bearing limit of the air bag. When the inflation exceeds a safety threshold, a negative feedback regulation model established between a sensing system in the air bag and the control unit sends a control signal to the air pump to stop the inflation of the air pump, so that the pressure and the temperature in the air bag are kept appropriate, and the situations of overpressure or over-temperature and the like are avoided, thereby ensuring the use safety;
the air pump is tightly connected with the air bag body through rubber, and the air bag can maintain a relatively stable state. If the outer air bag collides and extrudes with other objects in the driving process, the sensing system in the air bag senses the pressure change and feeds back the pressure change to the control unit, and the control unit transmits warning information to a driver to remind the driver that the outer air bag collides;
if the sealing degree between the air pump and the air bag body is reduced after the air bag is used for a long time, the internal pressure of the air bag body cannot be guaranteed to be at an absolute constant value. When the internal pressure of the air bag body is reduced in the using process of the air bag, the internal sensing system of the air bag can also feed back to the control unit to control the air pump to inflate the inside of the air bag and monitor and adjust the gas state in the air bag body in real time;
if the external temperature changes during use, the internal pressure of the air bag body can be influenced. The sensing system in the air bag can also sense the pressure change, and is matched with the control unit and the air pump to monitor and adjust the gas state in the air bag body in real time;
the system is closed by a manual control running path and an automatic control running path, and specifically instruction information transmitted by a driver manually operating a center console or a vehicle auxiliary driving system;
and when the control unit receives command information for closing the system, the air pump is controlled to start air suction. The outer airbag body is vacuumized through a negative feedback regulation model established between the airbag air pump sensing system and the control unit so as to ensure that the outer airbag body is tightly attached to the surface of the vehicle body and the normal running condition of the vehicle is prevented from being influenced;
the first embodiment is as follows:
as shown in fig. 3, when the vehicle is about to park, the driver may perform control operations through the center console. After the driver presses the confirmation key, the manual control operation path is switched on, and an instruction for starting the operation is sent to the control unit.
And after receiving the command of starting the work, controlling the corresponding control air bag to inflate the outer air bag body attached to the vehicle body.
Before the inflation begins, the original state of the air bag is vacuum and clings to the automobile body, so that the influence of resistance on the normal running of the automobile is avoided in the running process. In the inflation process, the sensing system in the air bag is connected with the control unit and used for protecting the air bag when the air pump is started to inflate the air bag, and the air bag is prevented from being damaged due to the fact that inflation exceeds the bearing limit of the air bag. When the air inflation exceeds the safety threshold, the sensing system in the air bag feeds back to the control unit, the power supply of the air pump is disconnected, the air pump stops inflating the bag body, and the pressure and the temperature in the air bag are ensured to be proper.
Due to the limited parking space, the vehicle may be scratched by other objects during parking. If the parking space is extremely narrow, the driver can avoid slight rubbing by the outer airbag and even find the optimal parking distance under the condition that the ultrasonic radar is not accurate enough. If the outer airbag collides and extrudes with other objects, the sensing system in the airbag senses pressure change and feeds back the pressure change to the control unit, and the control unit transmits warning information to a driver to remind the driver that the outer airbag collides, and the vehicle is indicated to run to the minimum distance and should stop running in the original direction or run in the reverse direction.
After parking is finished, the driver can operate the center console to close the outer airbag system through a manual control operation path. The closing instruction can be transmitted to the air pump through the control unit, the air pump pumps air to the external air bag, and a sensing system in the air bag monitors the air bag. And finishing the work of the air pump until the air bag is completely attached to the vehicle body after being vacuumized, and finishing the whole process.
Example two:
as shown in fig. 4, when the vehicle is in a normal driving state, if the sensing system of the vehicle driving assistance system finds that the vehicle is likely to collide, the early warning information is quickly transmitted to the control unit, and the air pump is started to quickly respond by automatically controlling the running road, so that the outer airbag body at the side, which is judged by the vehicle driving assistance system to be collided, is quickly inflated with the maximum power.
There is a point to explain specifically: if the speed of a vehicle is faster, the air bag body can not be filled before the collision happens, but the damage caused by rigid collision can be relieved to a certain extent no matter whether the air bag body is filled or not.
After the outer air bag is opened, if the vehicle collides with other objects, the sensing system in the air bag senses obvious impact pressure and feeds the impact pressure back to the control unit. The system will then alert the driver that the vehicle has collided.
After the outer airbag is opened, if the vehicle does not collide with other objects, the airbag interior sensing system does not sense an apparent impact pressure. After the air bag body is filled for 10s, if the system still does not sense collision, the control unit starts the air pump to pump air, so that the air bag body is vacuumized and is tightly attached to the surface of the vehicle body again, and the influence on the normal running of the vehicle is avoided.
The above description is intended to be illustrative of the preferred embodiment of the present invention and should not be taken as limiting the invention, but rather, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
