<P>PROBLEM TO BE SOLVED: To simplify structure, to reduce cost, to be conveniently detachably mounted onto a vehicle, and to easily detect even a light accident to automatically conduct radio notification. <P>SOLUTION: This detector is provided with a sensor means 2 comprising the first acceleration sensor 2a for detecting a longitudinal-directional acceleration, and the second acceleration sensor 2b for detecting a lateral-directional acceleration, a computing part 5 having a composition computing part 20 for finding a vector-sum √(Xa<SP>2</SP>+Xb<SP>2</SP>) of acceleration outputs Xa, Xb from the first and second acceleration sensors 2a, 2b to obtain a composed acceleration A, a comparison computing part 21 for comparing the composed acceleration A with a collision determining part A0, and an output part 22 for outputting a collision signal 4 when a comparison result therein is A>A0, and a radio means 6 for transmitting the collision signal 4 from the output part 22 to an outside of the vehicle by radio. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
