Title:
VEHICLE CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2011/052305
Kind Code:
A1
Abstract:
Disclosed is a vehicle controller capable of accurately determining the onset of the torque phase during gear change operations. The vehicle controller controls a vehicle drive device that is provided with: an input member which is connected to and driven by a driving power source; an output member which is connected to and drives the wheels; and a transmission which is equipped with both a plurality of engaging elements and a plurality of switchable gear positions. The vehicle controller controls the switching of gear positions occurring through the torque phase (Pt) by controlling the engagement and release of the plurality of engaging elements. The controller is provided with: a release control means which implements feedback control of the application of hydraulic pressure to release-side elements so that the differential rotation speed (ΔN) is substantially constant; an engagement control means which increases the application of hydraulic pressure to the engagement-side elements when the differential rotation speed (ΔN) is substantially constant; and a phase determination means which identifies the onset of the torque phase (Pt), upon detecting the phenomena occurring along with a change in the differential rotation speed, said change resulting from the increase in hydraulic pressure applied to the engaging side elements.
