Abstract: A method for detecting accidents is described. The method has the following operating steps: obtaining at least two axial accelerations; integrating at least one first axial acceleration and one second axial acceleration of said at least two axial accelerations for obtaining at least two axial acceleration integral values; calculating an energy modulus according to the at least two axial acceleration integral values; and comparing the energy modulus with an energy threshold. An apparatus and a system which can carry out the method is also described. Furthermore, vehicles that have the apparatus are described as well.

Abstract: A method for positioning an impact detection device on a fork of a vehicle supporting a wheel of the vehicle, in which the fork has a right-hand rod-shaped member and a left-hand rod-shaped member is described. The impact detection device has at least one first sensor unit associated with the right-hand rod-shaped member and a second sensor unit associated with the left-hand rod-shaped member. The second sensor unit is mounted inverted or rotated by an angle of 180 degrees around a steering axis of the wheel.

Abstract: A method for positioning an impact detection device on a rod-shaped member of a fork of a vehicle supporting a wheel of the vehicle is described. The detection device has at least one group of three accelerometers arranged on three axes orthogonal to each other and mounted on at least one printed circuit board, the at least one printed circuit board being arranged in a plane parallel to a longitudinal axis of the right-shaped member of the fork.
