摘要： An engine is restarted in response to an idle stop OFF command at t1 so that a gear shift control purpose hydraulic pressure is raised according to a working oil from an engine driven oil pump. An idle stop release time control of the engine is allowed according to a torque down unnecessary determination when a gear shift control purpose hydraulic pressure has reached to a set hydraulic pressure at t2. In a case where this allowance causes an engine torque Te to be raised from a torque down value toward a driving operation corresponding value by a predetermined gradient ΔTe1, a command value of a starting frictional element engagement pressure Ps is set to a control maximum value during the idle stop control including during the idle stop release time control.

摘要： In a hydraulic control system for a transmission, line pressure Pl is adjusted in accordance with a second solenoid pressure Psls if the ratio of a first sheave pressure Pin with respect to a second solenoid pressure Psls is equal to or less than the gain α. If not so, the line pressure Pl is adjusted in accordance with the first sheave pressure Pin. Consequently, the gain η of the first sheave pressure Pin with respect to a first solenoid pressure Pslp at a first sheave pressure adjustment valve 16 and the gain α of a second sheave pressure Pout with respect to the second solenoid pressure Psls at a second sheave pressure adjustment valve 17 can be individually set while the line pressure Pl can be suppressed to the substantially requisite minimum in the entire control region.

摘要： Greater one of a secondary pressure comparison reference value (Psec_b) and a primary pressure comparison reference value (Ppri_b) is set as a line pressure target value (Plin_tg). At a vehicle constant speed travel control, a value obtained by adding a first offset amount (γ) to the secondary pressure target value (Psec_tg) is the secondary pressure comparison reference value (Psec_b) and a value obtained by adding a second offset amount (γ) to the primary pressure target value (Ppri_tg) is the primary pressure comparison reference value (Ppri_b). By setting a line pressure in this manner, an occurrence of fluctuation of an engine speed at during executing the vehicle constant speed travel control is suppressed.

摘要： Disclosed is a hydraulic control device for a continuously variable transmission which changes the transmission gear ratio by changing the hydraulic pressure (Pin, Pout) supplied to hydraulic pressure chambers (134, 154) for pulleys in the continuously variable transmission via control valves (217, 218) is changed. In this hydraulic control device, line pressure regulation hydraulic pressure (Psrv) which corresponds to the magnitudes of the oil pressure (Pin, Pout) supplied to the hydraulic pressure chambers (134, 154) is introduced into a regulator valve (212), and line pressure (P1) which is input into the control valves (217, 218) according to the magnitudes of the oil pressure (Pin, Pout) is subjected to feedback regulation. In the hydraulic control device for the continuously variable transmission, after the valve element (217a) of the control valve (217) is driven in the valve opening direction, a vibration restriction control operation which temporarily restricts the displacement of the valve element (217a) is executed.
