Control system and method for realizing self-adaptive airbag explosion based on in-cabin monitoring

Abstract

The invention discloses a control system and method for realizing self-adaptive airbag explosion based on in-cabin monitoring. The system comprises an image acquisition module, a visual processor, a vehicle state sensing module, an airbag processor and a gas generator. The image acquisition module is used for acquiring a monitoring image in a cockpit; the visual processor is used for preprocessing the monitoring image; the vehicle state sensing module is used for sensing the state of the vehicle; and the airbag processor is used for obtaining driver feature information according to the preprocessed monitoring image, judging whether an airbag explosion condition is met or not according to the vehicle state sensing information and the driver feature information, and triggering the gas generator to perform multi-stage ignition according to different driver features. According to the control system and method for achieving self-adaptive air bag explosion based on in-cabin monitoring, multi-stage self-adaptive explosion of the air bag is achieved on the basis of fusion of visual information and vehicle state sensing information, and more specialized air bag protection is customized for human bodies of different figures.

Description

technical field [0001] The invention relates to the technical field of vehicle passive safety, in particular to a control system and method for realizing adaptive airbag ignition based on in-cabin monitoring. Background technique [0002] In a vehicle collision, the driver's airbag can protect the driver and reduce injuries to personnel in the event of a vehicle collision. However, the current driver's airbag is often developed based on the 50th percentile of adult males, and it is difficult to completely cover it. For other types of human bodies, when the driver is not in the best seating position without knowing the driver's body characteristics and sitting posture, the airbag is difficult to play its due protective role. On the contrary, if the airbag explodes, it will cause the driver unnecessary harm to personnel. [0003] Therefore, there is an urgent need for a control system and method for realizing adaptive airbag ignition based on in-cabin monitoring. Contents o...
