Abstract： |
The single-point and three-direction safety air bag controller for vehicle safety includes one control system and one program controlling software. The control system consists of power supply, monitoring circuit, monochip computer, acceleration sensor, ignition and detection circuit, air bag checking circuit and pilot lamp and communication interface for outer contact. The program controlling software includes main program, acquisition and interruption program, communication and interruption program and command processing sub-program. After the monochip computer and the acceleration sensor measure the acceleration signal, the program controlling software completes analysis and processing before execution. The present invention can distinguish collision from outer interference signal, output ignition pulse, control air bag inflation and prompt overspeed. |
