PROBLEM TO BE SOLVED: To provide a serious accident detection device which can detect occurrence of a serious accident between a vehicle and a vulnerable road user with high accuracy.SOLUTION: A serious accident detection device includes a first collision detection sensor 1, a first collision determination part 41 which determines whether a collision between a vehicle and a vulnerable road user occurred or not, second collision detection sensors 2, 3 which detect a collision at a predetermined collision dangerous portion A of a front portion of a vehicle, a second collision determination part 42, and an accident determination part 43. The second collision detection sensors 2, 3 include a microphone 3. The second collision determination part 42 determines whether the collision between the vulnerable road user and the collision dangerous portion A occurred or not based on a collision sound detected by the microphone 3. When the second collision determination part 42 determines that the collision occurred within a predetermined time after the first collision determination part 41 determines that the collision occurred, the accident determination part 43 determines that a serious accident occurred. |
