Intelligent airbag deployment algorithm design and implemented by DSP chip

An improved algorithm design methodology of vehicle airbag deployment decision is proposed in this paper. Firstly, the vehicle impact severity is analyzed to get four characteristic factors utilized as fuzzy inputs. From these four characteristics factors, the 'two stages fuzzy algorithm' is developed and used as the airbag deployment algorithm to identify the vehicle impact severity. Secondly, the algorithm is translated as machine codes download to DSP 6X chip by MATLAB/spl trade/ software. Finally, the Lab View/spl trade/ software is used to generate crash data to test the developed algorithm. Simulation results for different vehicle crash data demonstrate the validity and effectiveness of the proposed design methodology.
