Abstract
(EN)
In the present invention: a first value is determined on the basis of a physical quantity related to a magnet magnetic-flux output from a stroke sensor, such first value being a physical quantity related to the magnitude of the magnet magnetic-flux density with respect to the displacement of a push rod; and the first value and a second value are compared, the second value being a physical quantity related to the magnitude of the magnet magnetic-flux density with respect to the displacement of the push rod which was set beforehand.

Dans la présente invention : une première valeur est déterminée sur la base d'une quantité physique liée à une sortie de flux magnétique d'aimant provenant d'un capteur de course, cette première valeur étant une quantité physique liée à l'amplitude de la densité de flux magnétique d'aimant par rapport au déplacement d'une tige de poussée ; et la première valeur et une seconde valeur sont comparées, la seconde valeur étant une quantité physique liée à l'amplitude de la densité de flux magnétique d'aimant par rapport au déplacement de la tige de poussée qui a été définie au préalable.
