Title:
POWER TRANSMISSION DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2014219033
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress a torque variation of a power transmission device for a vehicle in which a plurality of crank-type gear change units are arranged in parallel in the axial direction.SOLUTION: In a plurality of gear change units 14, since phases of respective eccentric members 19 differ from one another, and a plurality of the gear change units 14 alternately transmit torque during one rotation of an input shaft, the total value T of actual output torque transmitted by the plurality of gear change units 14 is varied. However, since actual torque calculation means M2 calculates the total value T of the respective actual output torque of the plurality of gear change units 14 from a gear change ratio i and an eccentric amount ε, target output torque calculation means M3 calculates the total target output torque T' of the plurality of gear change units 14 on the basis of the request from a driver, and eccentric amount control means M4 controls the eccentric amount ε of the eccentric member 19 by controlling a gear change actuator 23 so that the total value T of the actual output torque coincides with the target output torque T', a variation of the total value T of the actual output torque can be suppressed.
