摘要： First temporary capacity reduction control that when acceleration ON is judged during coasting lock-up, brings lock-up clutch (20) into slip state by decreasing torque transmission capacity of lock-up clutch and subsequently returns lock-up clutch to lock-up state by increasing torque transmission capacity is executed. Control unit performing second temporary capacity reduction control that when return of accelerator pedal depression is judged during the progress of returning to lock-up state, decreases torque transmission capacity again and subsequently returns lock-up clutch to lock-up state by increasing torque transmission capacity is provided. In second temporary capacity reduction control, torque transmission capacity is decreased with predetermined torque transmission capacity by which lock-up clutch is not fully disengaged being lower limit value. Abrupt engagement of lock-up clutch and engine racing can be therefore avoided when acceleration is changed from ON to OFF during control of lock-up clutch from disengagement or slip state to lock-up state.

摘要： A start request detection unit detects a start request for a vehicle. A hydraulic pressure control circuit controls torque transmitted by a lock-up clutch by controlling an engagement force of the lock-up clutch. A rotation speed detection unit detects an output rotation speed of a torque converter. An engagement control unit issues an instruction to the hydraulic pressure control circuit such that the lock-up clutch is placed in slip engagement and is able to transmit the torque when the following conditions are both satisfied: a predetermined time period has elapsed since detection of the start request by the start request detection unit; and the output rotation speed has increased to a predetermined rotation speed or higher.

摘要： Greater one of a secondary pressure comparison reference value (Psec_b) andaprimarypressure 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： It controls, when EV mode is selected, belt clamping pressure on the basis of discharged oil from a main oil pump (14) which is driven by a motor generator (4). This control device for a FF hybrid vehicle is provided with a motor controller (83) that performs control such that when a vehicle is stopped in EV mode and a creep cut condition which does not require creep torque from the motor generator (4) is met, a first motor idling rotation speed Nma1 is set as a motor rotation speed. When the vehicle is stopped in EV mode and a standby learning controlling means completes learning of a zero-point oil pressure command value, the motor controller (83) reduces the rotation speed of the motor generator (4) to a second motor idling rotation speed Nma2 which is lower than the first motor idling rotation speed Nma1.
