A collision detection unit corrects a threshold value to a larger value, which a collision check unit uses to compare an output value of a collision detection unit, in case of a rough road surface than in case of a flat road surface. Thus, it becomes possible to suppress erroneous detection on the rough road surface while detecting a collision sensitively on a flat road surface. The rough road is detected by a vibration detection unit provided in a tire side device.
