PURPOSE:To sense the velocity at the time the stroke amount decreases rapidly with high precision by determining the stroke velocity VNEW from K.DELTAX0/(n.DELTAt) one by one in compliance with increase of (n) when the stroke amountDELTAX is maintained below the specified level DELTAX0. CONSTITUTION:A potentiometer 26 senses the stroke position of a damper 18 at certain intervals DELTAt. When the stroke amount DELTAX is maintained for example below the specified level DELTAX0 corresponding to the min. sensing amount, the stroke velocity VNEW is determined from K.DELTAX0/(n.DELTAt) one by one in compliance with increase of (n) under the assumption that the time when DELTAX becomes below DELTAX0 is n=1. Thereby the velocity when the stroke amount DELTAX decreases rapidly can be sensed with high precision. |
