Abstract
A method for detecting a collision of a vehicle based on an output value of a pressure sensor for detecting change of a pressure in an interior space of the vehicle, includes: a process for calculating an environmental pressure around the vehicle; a process for correcting a pressure value determined based on the output value of the pressure sensor in accordance with the calculated environmental pressure; and a process for determining whether the corrected pressure value exceeds a predetermined threshold.
