Title:
CONTROL APPARATUS FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2010/079665
Kind Code:
A1
Abstract:
When switching to a shift stage having a smaller transmission gear ratio during regeneration, both the suppression of shift shock generation and the improvement of energy efficiency are achieved.
A control apparatus for a vehicle driving apparatus provided with an input member which is drive-connected to an engine and a rotational electrical machine; an output member; and a transmission device comprising a plurality of frictional engagement elements so that a plurality of shift stages are switched by controlling engagement and disengagement of the plurality of frictional engagement elements, and a rotational driving force of the input member is changed by a transmission ratio of each shift stage and output to the output member, wherein when the transmission device switches to a shift stage having a smaller transmission gear ratio, under the conditions that the rotational electrical machine is regenerated, a disengagement side hydraulic pressure which is a hydraulic pressure of operating oil with respect to a disengagement side element representing the frictional engagement element at the disengagement side is controlled, and the disengagement side element is maintained in a slipping condition during the entirety of the shift transmission process.
