Abstract: A vehicle information recording apparatus for a vehicle includes a collision determination section and an information management section. The collision determination section determines the presence or absence of a collision between the vehicle and an object based on (i) detection values of impact sensors which detect impacts applied to the vehicle and (ii) detection values by proximity sensors which detect an approach of the object to the vehicle. The information management section records collision data concerning the collision based on a determination result by the collision determination section. This enables a detection of a collision with an object as a recording target while reducing influence of vibration or noise.

Abstract: In a pedestrian collision detection system, a mobile communication device is owned by a pedestrian, and a pedestrian collision detection device is disposed in a vehicle. A mobile-side impact detection part detects a collision between the vehicle and the pedestrian. A short-distance communication part enables wireless communication within a predetermined range. A vehicle-side collision detection part detects the collision. A wireless communication part enables wireless communication within a predetermined range. The wireless communication part and the short-distance communication part perform mutual authentication through pairing when the vehicle-side collision detection part detects the collision and a result of the detection is held by an impact record part.
