Abstract
An automatic door lock releasing apparatus according to the present invention comprises decelerating direction integrating means for integrating a decelerating direction component of each of the acceleration signals obtained from acceleration sensors in a vehicle; accelerating direction integrating means for integrating an accelerating direction component; coefficient means for weighting an output of the accelerating direction integrating means with a specified coefficient; subtracting means for subtracting an output of the coefficient means from an output of the decelerating direction integrating means; an arithmetic processing unit for determining a resultant velocity of velocity signals; and a comparison processing unit for comparing the resultant velocity with a threshold value and generating a start signal.
