Title:
FRICTION TRANSMISSION MECHANISM CONTROLLER
Document Type and Number:
Japanese Patent JP2016017524
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a friction transmission mechanism controller capable of improving accuracy for setting a control reference position.SOLUTION: A shift controller 9 is a friction transmission mechanism controller configured to perform reset processing (processing in a flowchart of FIG. 4) for revolving a crankshaft 3 eccentrically supporting driven rollers 31 and 32 of two roller pairs 10 and 20 to a restricted position by a stopper pin 72 and a revolving guide groove 71 and setting this position as a zero point, and restricted position discrimination processing for discriminating whether a revolution-restricted position is the restricted position or a position of a crest of a pressing force by applying to the crankshaft 3 a driving force in a negative revolution direction that is a direction of the restricted position by a reset torque that cannot surpass the crest of the pressing force at the time of revolving the crankshaft 3 to the restricted position, and to perform surpassing processing for revolving the crankshaft 3 to surpass the crest of the pressing force and then revolving the crankshaft 3 toward the restricted position with the reset torque if it is discriminated that the revolution-restricted position is the position of the crest of the pressing force.SELECTED DRAWING: Figure 1
