Abstract:
A device for starting an occupant crash protector, comprising:an acceleration sensor for detecting an acceleration at the time of a collision;collision determining means for detecting said collision including a shock that does not require a start signal based on the output of said acceleration sensor;subtracting and integrating means for subtracting a value varied with time from the output of said acceleration sensor, and integrating the result of said subtraction;non-collision determining means for setting a value greater than a peak value of a subtracted and integrated value at the time of said shock that does not require a start signal, based on said output of said subtracting and integrating means, as a first threshold, comparing said value with each output of said subtracting and integrating means, and detecting only a collision requiring a start signal based on the result of the comparison, said non-collision determining means comprising a first comparing means; andfirst ANDing means for outputting a logical product of the output of said collision determining means and the output of said non-collision determining means as a start signal.
