Title:
ROTATION OPERATION DEVICE HAVING REACTION FORCE CONTROL FUNCTION
Document Type and Number:
Japanese Patent JP2015180124
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotation operation device having a reaction force control function capable of reliably holding a rotation operation part when the rotation operation part is located in an anchor region in so called reaction force control.SOLUTION: Operation reaction force with reference to a rotation operation part is set by a stepping motor. The stepping motor is driven by two-phase excitation, a control current Iac, Ibd corresponding to an angle of an anchor position where the rotation operation part should be stopped is calculated and this control current is supplied to a control coil of the stepping motor. The rotation operation part is pulled in so as to return to the anchor angle. When the rotation operation part is rotated at a position deviated from the anchor region, reaction force is set by motor control.
