<p><P>PROBLEM TO BE SOLVED: To provide an acceleration calculation device or the like which is capable of performing appropriate evaluation on the basis of an actually measured value of acceleration. <P>SOLUTION: The acceleration calculation device includes: a long-term acceleration calculation part which calculates a long-term acceleration being an average value of measured accelerations measured in a predetermined time range; a difference acceleration calculation part which calculates difference accelerations resulting from subtracting the measured accelerations from the long-term acceleration; a variation width calculation part which calculates a positive-direction variation width being a variation width of difference accelerations in a period when the sign of difference accelerations is positive, and calculates a negative-direction variation width being a variation width of difference accelerations in a period when the sign of difference accelerations is negative; a weight calculation part which calculates weights for the measured accelerations in such a manner that the larger difference between the positive-direction variation width and the negative-direction variation width is, the more the weights for the measured accelerations are heavier than those for the long-term acceleration; and an acceleration calculation part which calculates weighted accelerations resulting from weighting the measured accelerations and the long-term acceleration by the weights, as corrected accelerations. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
