Rotary solenoid drive control method

A rotary solenoid drive control method for controlling driving of a rotary solenoid including:

• a fixed body portion having a casing in which a pair of bearing portions positioned on front and rear sides are provided;
• and
• a movable body portion having a rotation shaft rotatably supported by the pair of bearing portions, wherein
• the movable body portion is configured to reciprocate in a rotation angle range between a first position and a second position according to energization control of a driving coil and to be stopped at the first position and the second position by a pair of self-holding mechanisms by restriction of a pair of restricting stopper mechanisms and attraction of magnets, and
• when controlling switching from the second position (or the first position) to the first position (or the second position), after a driving voltage based on a driving pulse is applied to the driving coil, if the movable body portion has reached a predetermined intermediate position in 10 to 50 [%] of the rotation angle range, control is performed so that application of the driving voltage is stopped.
