摘要： PROBLEM TO BE SOLVED: To prevent the backlash propagation shock of a driving system during resetting neutral control.
SOLUTION: An ECT_ECU executes a program including a step (YES in S120) for determining neutral control, a step for determining that a vehicle is moved forward during the neutral control when a rotating speed NIN of a primary pulley is a threshold value or higher (YES in Step 140) as a brake switch remains on (YES in S150), a step (S170) for executing backlash propagation processing until a predetermined time passes (YES in S190), and a step (S200) for executing normal resetting processing of the neutral control after backlash reducing processing.

摘要： PROBLEM TO BE SOLVED: To suppress the slippage between the belt of a belt type continuously variable transmission and a pulley after a friction engagement device is engaged in starting a vehicle.
SOLUTION: In starting the vehicle, oil is supplied from a first route 36 to a forward clutch 16 or a reverse brake 17. By drivingly controlling a garage shift control valve 39 in the first route 36, hydraulic pressure acting on the forward clutch 16 or the reverse brake 17 is controlled so that the forward clutch 16 or the reverse brake 17 can be smoothly engaged. After the forward clutch 16 or the reverse brake 17 is engaged, oil supply through the first route 36 is continued until a specified time t is passed. Thus, oil is supplied through the first route 36 to those portions of the forward clutch 16 or the reverse brake 17 where oil is not filled. When the specified time t is passed, oil is supplied to the forward clutch 16 or the reverse brake 17 through a second route 37 by changing over a garage shift valve.

摘要： PROBLEM TO BE SOLVED: To provide a vehicular lock-up clutch controller which suppresses variation in learning hydraulic pressure for determining an engaged state.SOLUTION: When performing shift control of a continuously variable transmission 18 during engagement control of a lock-up clutch 26, in the case where a deviation ΔNbetween a target input rotating speed N* in that continuously variable transmission 18 and a present input rotating speed Nis settled within a specific range, hydraulic pressure learning control is executed. Therefore, in the case where the deviation ΔNbetween the target input rotating speed N* in the continuously variable transmission 18 and the present input rotating speed Nis settled within the specific range and it is determined that overshoot of that continuously variable transmission 18 does not occur, by executing hydraulic pressure learning control, appropriate learning control in which learning variance hardly occurs can be performed.

摘要： PROBLEM TO BE SOLVED: To provide a control device for a vehicle that improves fuel consumption while ensuring drivability during slip control of a lock-up clutch upon starting a vehicle.SOLUTION: The control device for the vehicle is used in a vehicle mounted with a torque converter including a lock-up clutch. When executing slip start control for making the lock-up clutch into a slipping state upon starting a vehicle, an ECU sets an optimum target engine rotational speed Netgtcalculated by considering fuel consumption on the basis of a vehicle state. In order to quickly bring an actual engine rotational speed Ner close to the target engine rotational speed Netgt, if the accelerator opening Acc is large, the ECU increases an amount S of sweep of a target engine rotational speed Netgtset at the start of the slip start control, when bringing the target engine rotational speed Netgtclose to the target engine rotational speed Netgt.

摘要： PROBLEM TO BE SOLVED: To provide a control device of a power transmission device for a vehicle capable of securing the durability of a lockup clutch by suppressing the continuation of a minute slip rotational speed.
SOLUTION: When the flex start control of the lockup clutch 26 is performed along with the shift control of a continuously variable transmission 18, if a state in which an input/output rotational speed difference N
SLP (=N
E -N
T ) is smaller than a determined rotational speed difference value N1
SLP continues for a determination time TIME
SLP or longer, the flex start control is released, and a sweep-up control to operate the lockup clutch 26 in the direct coupling direction is performed. Therefore, the control device can suppress that the input/output rotational speed difference (slip rotational speed) N
SLP does not converge to zero but continues with a minute difference. Since the heating of the lockup clutch 26 due to the continuation of the minute input/output rotational speed difference N
SLP is suppressed, the durability of the lockup clutch 26 can be secured.

摘要： PROBLEM TO BE SOLVED: To provide a shift control device capable of preventing a belt slip in starting of a vehicle, restricting a starting failure of the vehicle, in regard to a belt-type continuously variable transmission. SOLUTION: In the case wherein a continuously variable transmission 18 is not in the most decelerating condition in stop of a vehicle, a belt pinching pressure control means 156 raises the belt pinching pressure Pd so as to be higher than the normal value Pd_rg during the feedback control of a transmission ratio γ, and on the other hand, during the sealing control, it does not change the belt pinching pressure Pd relative to the normal value Pd_rg. With this structure, a starting failure of the vehicle by upshift due to a change of a thrust ratio τ is restricted during the sealing control. Further, even if downshift is preformed to obtain the maximum transmission ratio γmax of the transmission ratio γ of the continuously variable transmission 18 in starting of the vehicle, a belt slip due to a transitional decrease of friction force between a variable pulley 42, 46 and a transmission belt 48 can be prevented.
