ABSTRACT:
To prevent short-time energization of an air bag due to a bit error occurring in a safing ON/OFF command, the invention provides an air bag control apparatus comprising a first electronic circuit (3) for generating a firing command based on an output of a main acceleration sensor (1), a second electronic circuit (4) for generating a safing ON command for clearing a safing state, based on an output of a safing acceleration sensor (2), and a firing circuit (8) for generating an air bag inflation permit signal when the firing command and the safing ON command are both input, wherein the second electronic circuit (4) generates a safing OFF command separately from the safing ON command, and sets the safing state by the safing OFF command.
