Title:
SHIFT CONTROL DEVICE FOR HYBRID VEHICLE DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/203709
Kind Code:
A1
Abstract:
In order to achieve completion of a shifting operation in a short time while ensuring good drivability, a shift control device for a hybrid vehicle drive device is provided with: a shift time computing unit that computes a shift line arrival predicted time from the current time; a clutch-disconnection preliminary control transition determination unit; an engine torque decrease control unit that decreases engine torque to an engine torque threshold value; a clutch torque decrease control unit that decreases clutch torque to a clutch torque threshold value; a demand torque control unit; a clutch-disconnection control unit that, when the rotational speed of an output shaft exceeds a shift line, performs fuel-cut control to decrease the engine torque down to zero or below, and activates a clutch drive mechanism at a maximum drive speed so as to place the clutch in disconnected state; and a shift stage switch unit.
