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.

摘要： In a vehicle equipped with a torque converter 4 having a lock-up clutch (3), learning control for obtaining a learning value (L_n) on the basis of meet-point information, with which the lock-up clutch (3) initiates torque transmission, is carried out. When the lock-up clutch (3) experiences a transition to an engaged state during travel, a meet-point learning control unit (12c) calculates an LU transmission torque estimate on the basis of the difference between the engine torque (engine torque signal value Te) and the torque converter transmission torque (τ·N 2 ). Excess clutch capacity is detected when the LU transmission torque estimate is greater than an excess capacity determination transmission torque threshold within a prescribed amount of time after an initial pressure (P_n) based on the learning value (L_n) is instructed. When excess clutch capacity is detected, a learning value correction that reduces the learning value (L_n) is carried out.

摘要： Provided are a variator (20) and a transmission controller (12) in an engine-driven vehicle. The transmission controller (12) has an instantaneous interruption recovery control portion ( FIG. 4 ) configured to, upon a power reset from an instantaneous interruption during running, set a target through transmission ratio (vRATIO0) and a desired through transmission ratio (vDRATIO) to a lowest transmission ratio value by initialization and perform recovery control to recover an actual through transmission ratio (vRATIO) of the variator (20) to a transmission ratio value for shifting to normal control. The instantaneous interruption recovery control portion ( FIG. 4 ) is further configured to, upon the power reset from the instantaneous interruption during the running, set a change speed of the target through transmission ratio (vRATIO0) from the lowest transmission ratio value to the desired through transmission ratio (vDRATIO), to be higher than that under the normal control, before a time at which the desired through transmission ratio value (vDRATIO) deviates from the lowest transmission ratio value.

摘要： When a switch condition where a shift of a continuously variable transmission is switched from a first shift that is any one of an upshift and a downshift to another second shift is satisfied, an integral term in the feedback control of the first shift is reduced to zero with a first predetermined gradient, an operation of an integral term in the feedback control of the second shift is started after the switch condition is satisfied and before the integral term in the feedback control of the first shift reaches zero, and the continuously variable transmission is shifted based on a sum of the integral term in the feedback control of the first shift and the integral term in the feedback control of the second shift.
