Abstract:
1. A pedestrian collision detection apparatus for a vehicle, the apparatus comprising: a bumper sensor configured to detect a deformation of a bumper of the vehicle, a load applied to the bumper, or a pressure applied to the bumper; an acceleration sensor configured to detect an acceleration of the vehicle; and a pedestrian collision determination unit configured to include a two-dimensional map for defining a correlation between a first parameter and a second parameter when colliding with a pedestrian, the first parameter being equivalent to a deformation of the bumper calculated based on an output from the bumper sensor, the second parameter being equivalent to an impact applied to the vehicle calculated based on an output from the acceleration sensor, and further configured to determine a collision with a pedestrian when a specified area of the two-dimensional map contains a point determined by a calculated maximum value for the first parameter and a calculated maximum value for the second parameter.
