Description

Vehicle protective airbag system

Technical Field

The present utility model relates to a vehicle protective airbag system, and more particularly, to a vehicle protective airbag system for use in an automobile or locomotive to reduce damage to the vehicle when impacted.

Background

Automobile safety is increasingly emphasized, and in addition to the increasing number of airbags, automatic Driving Assistance Systems (ADAS) are also commonly used to improve driving safety, for example: automatic Emergency Braking (AEB), lane Departure Warning (LDW), lane center maintenance (LCC), pedestrian Detection (PDS), adaptive cruise (ACC), etc.

The safety of the vehicle itself can be protected by technology, but the vehicle cannot be prevented from being impacted by other vehicles which are not operated properly or is affected in the event of accidents of other vehicles. In the existing vehicle safety technology, a safety belt and an airbag in a vehicle are used as the last defense line for protecting a driver and passengers, however, when the vehicle is impacted strongly, the vehicle body is deformed and crumpled, and even if the safety belt and the airbag are used, the safety of protecting the driver or passengers cannot be ensured.

A vehicle protective airbag system according to claim 3, wherein the threat detection apparatus is configured such that, when either side of the vehicle is impacted, the threat detection apparatus is capable of detecting a relative position and distance of an obstacle located around the vehicle and the vehicle, and judging a probability of collision of the obstacle and the vehicle by the collision evaluation unit, and generating a second collision judgment information in a case where it is judged that the probability of collision of the obstacle and the vehicle is equal to or higher than a safety threshold; the airbag deployment controller is configured to be able to control, in accordance with the second collision determination information, the deployment of at least one of the front side protection airbag, the rear side protection airbag, the left side protection airbag, or the right side protection airbag of the vehicle obstacle object corresponding to a side of the collision direction of the second collision determination information.

5. The vehicle protective airbag system of claim 4, wherein the threat detection apparatus further comprises a body position sensing unit for detecting a rollover of the vehicle, the threat detection apparatus being configured to generate a rollover determination message when a rollover of the body of the vehicle is detected; the airbag deployment controller is configured to be able to control at least one of the front side airbag deployment, the rear side airbag deployment, the left side airbag deployment, or the right side airbag deployment of the vehicle corresponding to a side of a direction in which the vehicle rolls, in accordance with the roll determination information.

6. The vehicle protective airbag system of claim 5, wherein the forward sense unit, the rearward sense unit, the left sense unit, and the right sense unit of the threat detection apparatus each have at least one sensor, at least one of the sensors being configured to: one or a combination of an ultrasonic sensor, a millimeter wave radar, a camera lens, a laser range finder, a depth camera and a laser radar.

7. The vehicle protective airbag system of claim 6, wherein the threat detection apparatus is configured to be coupled to a vehicle control apparatus of the vehicle, and wherein the threat detection apparatus is configured to control a strain action of the vehicle to one or more of accelerate, decelerate, displace, or steer by the vehicle control apparatus if it is determined that either direction of the vehicle and the probability of a threat object impact is equal to or above a safety threshold.

8. The vehicle protective airbag system according to claim 5, wherein the airbag protective device further includes another at least one upper protective airbag that is provided above the vehicle and is capable of covering the roof of the vehicle, the threat detection device is configured to be capable of detecting a threat object dropped from above the vehicle, and in a state where it is determined that a probability of collision between the threat object from above the vehicle and the vehicle is equal to or higher than a safety threshold, to generate one dropped threat information; the airbag deployment controller is configured to control deployment of at least one of the upper protective airbags above the vehicle in accordance with the drop threat information.

9. The vehicle protective airbag system of any one of claims 1 to 8, wherein the vehicle is an automobile, or a motorcycle, an electrically assisted bicycle, or a power driven light vehicle.

10. The vehicle protective airbag system according to any one of claims 4 to 8, wherein the rearward sense unit, the forward sense unit, and the right sense unit and the left sense unit of the threat detection apparatus are a plurality of sensors built into one autonomous driving assistance system of the vehicle; the threat detection apparatus is connected to the automated driving assistance system of the vehicle via a switching apparatus and enables the threat detection apparatus to communicate with a plurality of sensors of the automated driving assistance system via the switching apparatus.
