Abstract

The invention discloses an air bag control method and a corresponding air bag control system. The control method comprises the following steps: processing real-time image information obtained by a vehicle-mounted image pick-up device to determine a barrier collision type; and judging whether to initiate the air bag or not through the barrier collision type.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to the passive safety of automobiles, and more specifically to an airbag control method and an airbag control system. Background technique [0002] Automobile airbags are crucial to ensure the life safety of car occupants in the event of a collision. The current car airbag controller (Airbag Control Unit, ACU) algorithm for detecting collisions is based on acceleration. That is, when the car collides and generates a relatively large acceleration, the airbag controller recognizes the acceleration, thereby detonating the airbag. [0003] figure 1 The working flow of the existing airbag controller is shown. [0004] Such as figure 1 As shown, in step 101, the acceleration sensor senses the acceleration of the vehicle. [0005] In step 102, the ACU receives an acceleration signal from an acceleration sensor. [0006] In step 103, the ACU organizes and confirms the data of the accelerati...
