Title:
POWER TRANSMISSION CONTROL DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2016118290
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technique which is effective for alleviating a gear change shock at the up-shift of a gear change stage without increasing the number of parts, in a power transmission control device for a vehicle which controls clutch torque and the gear change stage of a transmission.SOLUTION: In a power transmission control device 100 for a vehicle, when a transmission T/M is upshifted to a high-speed stage from a low-speed stage, an electronic control unit ECU being control means which controls both a clutch actuator ACT1 and a transmission actuator ACT2 on the basis of a traveling state of a vehicle 10 adjusts a clutch stroke so that a clutch C/T is brought into a semi-joined state accompanied by a slide by the control of the clutch actuator ACT1, estimates a torque vibration curve which occurs after the upshift to the high-speed stage on the output torque of an output shaft A3 of the transmission T/M, and adjusts the clutch stoke so that clutch torque vibrates at a reverse phase which is reverse to a phase of the estimated torque vibration curve.SELECTED DRAWING: Figure 1
