Abstract
A starting device integrates an output signal of an acceleration sensor by a band-pass integrating means while restricting an upper limit of the output signal in a specified frequency range by an upper limit restricting means, and is provided with a comparing means for outputting a starting signal when the integrated value is larger than a predetermined threshold value. In this way, the starting device is certainly started by an acceleration waveform of collision that must start the device. Further, the device is not influenced by vibration components caused immediately after the beginning of collision with respect to a low-speed collision such as 8 mile/hour frontal collision that must not start the device.
