System and method for controlling external active safety airbag of vehicle on basis of ADAS (advanced driver assistant system) and IVI (in-vehicle information system)

Abstract

The invention discloses a system and a method for controlling an external active safety airbag of a vehicle on the basis of an ADAS (advanced driver assistant system) and an IVI (in-vehicle information system). The system comprises an external active safety airbag body of the vehicle, a distance sensor, a speed sensor and a first communication unit. The external active safety airbag body is connected with a computation control unit, the first communication unit is connected with the computation control unit, and a second communication unit of the in-vehicle information system and a third communication unit of the advanced driver assistant system are connected with the first communication unit by a vehicle body bus network; the advanced driver assistant system further comprises a sensor array, a camera array, a processor unit and a collision mode database unit, and the sensor array, the camera array, the processor unit and the collision mode database unit are connected with a data acquisition unit; the in-vehicle information system comprises a mobile communication unit; the mobile communication unit is used for issuing rescue seeking information to rescue seeking centers when the external active safety airbag body of the vehicle is ignited. The system and the method have the advantages that different types of vehicle collision can be actively coped, and accordingly personal casualties and property loss when vehicle collision accidents occur can be obviously reduced.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an automobile external active airbag control system and method based on an advanced driver assistance system ADAS and an on-vehicle infotainment system IVI. Background technique [0002] With the continuous development of the automobile industry, automobile safety has gradually become the primary factor considered by the majority of car owners when purchasing a car. Automotive safety systems are mainly divided into two categories, one is the active safety system, that is, the car safety system that warns or adjusts itself before the danger of the vehicle occurs, and prevents problems before they happen; the other is the passive safety system, that is, When a collision accident cannot be avoided, the vehicle safety system relies on the body structure of the vehicle itself, such as seat belts and interior airbags, to absorb the impact force. [0003] In the field of acti...

Problems solved by technology

However, the three-dimensional dynamics of the driving environment are changing rapidly, and any single-function sensor has limitations

Therefore, the existing active airbag control system on the outside of the car is obviously limited by the detection blind zone of the distance sensor, which is similar to "bottoming collision", "falling object collision", "falling collision" or "out of control rollover collision" and other collisions Accidents cannot be well identified and predicted
