<P>PROBLEM TO BE SOLVED: To provide an opening/closing body control unit which enables the opening/closing of an opening/closing body by determining the presence (or absence) of a user's opening/closing command operation for the opening/closing body or the periphery of the opening/closing body without false detection. <P>SOLUTION: This opening/closing body control unit 1 includes: an opening/closing command operation input part which is mounted on the opening/closing body or a structural member on the periphery of the opening/closing body, and into which the opening/closing command operation is input; a vibration detecting sensor 11 which is mounted via the opening/closing command operation input part, and which detects vibrations caused by the opening/closing command operation; and a determination means 40 for determining the presence or absence of the opening/closing command operation of the opening/closing body by the user, on the basis of at least either the amplitude ratio between an amplitude level of an upside waveform and that of a downside waveform with respect to the vibration standard of the vibration waveform or the time ratio between the time when an approximate line of the waveform falls short of the amplitude standard and the time when the approximate line of the waveform exceeds the amplitude standard, and an envelope curve acquired from a damped vibration waveform in which the predetermined frequency band of the vibration waveform is damped. <P>COPYRIGHT: (C)2010,JPO&INPIT |
