PROBLEM TO BE SOLVED: To provide a collision detection device capable of properly deciding a vehicle collision, even when a tire is punctured. SOLUTION: An airbag device includes a puncture detecting part B1, a filter part B2 and a collision deciding part B3. When the puncture detecting part B1 detects the puncture of the tire, the filter part B2 outputs detection results of satellite sensors 101 to 106 and a center sensor 100a by reducing specified signals caused by the puncture of the tire from the detection results. The collision deciding part B3 compares the detection results of the satellite sensors 101 to 106 and the center sensor 100a inputted from the filter part B2 with a decision threshold for each sensor to decide the vehicle collision. The vehicle collision therefore can be properly decided without being affected by the specified signals caused by the puncture, even when the tire is punctured. COPYRIGHT: (C)2011,JPO&INPIT
