摘要： An FF hybrid vehicle control device having an HEV mode and an EV mode as drive modes is provided with a CVT control unit (84) for determining primary pulley pressure (Ppri) and secondary pulley pressure (Psec) with which a belt (6c) of a belt-type continuously variable transmission (6) will be clamped on the basis of a torque component inputted to the belt-type continuously variable transmission (6) during brake deceleration, and the corrected amount of brake torque which is an inertia torque correction component. The CVT control unit (84) reduces the corrected amount of brake torque during brake deceleration when EV mode is selected to be less than the corrected amount of brake torque during brake deceleration when HEV mode is selected.

摘要： A transmission controller searches a mechanical High, which is a minimum value of a possible speed ratio of the continuously variable transmission (CVT), based on an actual speed ratio, sets a control High lower than the mechanical High by a predetermined amount, and controls a speed ratio of the CVT by setting a minimum value of a speed ratio range of the CVT at the control High.

摘要： A transmission controller determines whether a shift is a kickdown, and when the shift is determined as the kickdown, the target line pressure is increased to a first target pressure corresponding to an input torque to a continuously variable transmission increased by the kickdown; the transmission controller then determines whether the line pressure has reached the first target pressure, and if determined that the line pressure has reached the first target pressure, the target line pressure is increased to a second target pressure higher than the first target pressure.

摘要： A controller is provided so as to control, when an electric vehicle (EV) mode is selected, a belt clamping pressure on the basis of discharged oil from a main oil pump which is driven by a motor generator. The controller is provided for a hybrid vehicle and is configured to perform control such that when the vehicle is stopped in the EV mode and a creep cut condition which does not require creep torque from the motor generator is met, a first motor idling rotation speed is set as a motor rotation speed. When the vehicle is stopped in the EV mode and a standby learning control completes learning of a zero-point oil pressure command value, the controller reduces a rotation speed of the motor generator to a second motor idling rotation speed which is lower than the first motor idling rotation speed.
