Title:
CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/079714
Kind Code:
A1
Abstract:
Both the control of transmission shock due to transmission operation and improved energy efficiency will be achieved in cases when shifting to a low gear ratio gear in a state when the accelerator opening angle of a vehicle is at or below a specified value. Disclosed is a transmission device control device, which is equipped with an input member, which drive-couples to an engine and a dynamo-electric machine, an output member, and a transmission mechanism, which switches between multiple gears by controlling the engagement and disengagement of a plurality of frictional engagement elements, converts the rotational velocity of the input member by the gear ratio of the various gears and outputs the velocity to the output member. When shifting to a low gear ratio gear in a low accelerator opening state, the disengagement side hydraulic pressure, which is the hydraulic pressure of the hydraulic fluid for the disengagement side element on the side that is disengaged, is reduced to allow the disengagement side element to slip, and this slip condition is maintained throughout the transmission process from the time that said disengagement side element begins to slip until the time that the rotational velocity obtained by multiplying the rotational velocity of the output member by the gear ratio after shifting gears synchronizes with the rotational velocity of the input member.
