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

摘要： A hydraulic pressure controller includes belt sandwiching force increasing means. The belt sandwiching force increasing means increases a belt sandwiching force by a primary pulley and a secondary pulley on the basis of a braking force request from a driver, up to a predetermined value to prevent a belt from slipping due to a braking force. The belt sandwiching force increasing means increases the belt sandwiching force in a range of less than the predetermined value before the braking force request occurs.

摘要： An oil pump driving control device of a vehicle having a main oil pump (14) that is driven by a motor/generator (4) and produces a pump discharge oil to a first clutch (3), a second clutch (5) and a belt-type continuously variable transmission (6) provided on a driving force transmission line. A hybrid control module (81) is provided in this FF hybrid vehicle. The hybrid control module (81) is configured to perform a control so that during vehicle stop, the lower an ATF oil temperature is, the more the pump driving energy to drive the main oil pump (14) is decreased. With this control, consumption energy during the vehicle stop can be reduced.

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： A belt-type continuously variable transmission is equipped with a belt wrapped around across a primary pulley and a secondary pulley, and a CVT control unit for controlling pulley hydraulic pressures to the primary pulley and the secondary pulley. The CVT control unit determines whether an operating state is a driving state where the direction of an input torque inputted to the belt-type continuously variable transmission is from a driving source or a coasting state where the input torque direction is from drive road wheels. The pulley hydraulic pressure for the input torque for when it is determined that the operating state is the coasting state is set higher than the pulley hydraulic pressure for the input torque for when it is determined that the operating state is the driving state, thereby suppressing a slippage of the belt.

摘要： As a driving source, an engine and an assist motor are provided. An engine control module includes a torque assist control unit for controlling the assist motor by a plurality of types of switching patterns having different torque assist levels. A CVT control unit includes a torque assist coordination control unit that, when a torque assist request is input from the torque assist control unit, carries out the control that increases commanded hydraulic pressure so as to increase the hydraulic pressure of hydraulically operated members. When carrying out the control that increases the commanded hydraulic pressure, the torque assist coordination control unit unifies the levels of the commanded hydraulic pressure regardless of the types of the switching patterns.

摘要： The present invention is related to a vehicle including a motor-generator, a transmission, a shift hydraulic control unit, and a CVT control unit (CVTCU). When a downshift of the transmission is performed without an acceleration request from a driver, the CVTCU sets a pulley thrust at a secondary pulley on the basis of a first lower limit as a lower limit, which is a sum of a fundamental thrust and a first correction thrust. The CVTCU also sets a pulley thrust at a primary pulley on the basis of a second lower limit as a lower limit, which is a sum of the fundamental thrust and a second correction thrust.

摘要： Provided is a control device of an automatic transmission, by which a supercharger can be prevented from becoming high in temperature and deteriorating in durability. An automatic transmission is connected to an engine (1) in which a supercharger (2) is mounted and has a manual mode to manually select a desired gear ratio from a plurality of fixed gear ratios. A control device includes a manual mode detection unit, a temperature judgment unit (31) and a gear ratio changeover unit (43) arranged such that, when the manual mode detection unit detects that the automatic transmission is in the manual mode and when the temperature judgment unit judges that the temperature of the supercharger is higher than or equal to a predetermined value, the gear ratio changeover unit changes the gear ratio of the automatic transmission to a higher gear ratio and thereby lowers the rotation speed of the engine (1).

摘要： A control apparatus for a hybrid vehicle includes a low temperature time hydraulic control section (11a) to perform a low temperature time hydraulic control to restrain a discharge quantity of operating oil from an oil pump (4) by limiting a line pressure of a transmission (7) at an engine cold time to a predetermined value smaller than a maximum value of a line pressure command pressure for a predetermined time period. The hydraulic control by this low temperature time hydraulic control section (11a) is continued until the motor is started after the start of the engine and a first clutch (3) is engaged at the time of low temperature of engine (1). By so doing, the control apparatus can prevent the oil pump from being stopped by inappropriate starting timing of the low temperature time hydraulic control.

摘要： A control device for a vehicle having: an engine; a variator arranged downstream of the engine in a power transmission path connecting the engine and drive wheels; a mechanical oil pump that is driven by the engine and supplies hydraulic pressure to the variator; and an electric oil pump that supplies hydraulic pressure to the variator, wherein the control device for the vehicle has a controller that executes a low standby control which downshifts the variator by moving a belt of the variator in a radial direction during stopping of the vehicle. The controller limits an output of the engine and increases an amount of oil discharged by the electric oil pump when executing the low standby control.
