Abstract: An explosion detection apparatus (20) comprises a first path pickup means (21) for picking up a path portion ahead of the vehicle and generating first data describing the picked-up path portion, storing means (23) for storing the first path data, motion detection means (24) for detecting motion of the vehicle and generating motion data, a second path pickup means (22) for picking up a path portion underneath the vehicle and generating second, a comparing means (25) for comparing at least a portion of the first data with at least a portion of the second data in accordance with the motion data, and an explosion judging means (26) judging that an explosion has occurred when a predetermined difference between the compared data has been found. A vehicle may be equipped with such an apparatus and may comprise an emitter for generating counteracting forces upon detection.
