Abstract
A collision detection apparatus that is mounted in a vehicle and that determines whether an object has collided with a side surface of the vehicle from outside the vehicle includes: an acceleration detection portion that detects acceleration in a transverse direction of the vehicle which is applied to a door portion of the vehicle from outside; an integration execution portion that starts integration of the acceleration detected by the acceleration detection portion and finds velocity by integrating the acceleration if the detected acceleration is greater than or equal to a pre-set positive first threshold value, or is less than or equal to a pre-set negative second threshold value; and a collision determination portion that determines whether an object has collided with a side surface of the vehicle based on the detected acceleration and the velocity found by the integration execution portion.
