摘要： A corner determinator detects a corner appearing in a traveling direction of a vehicle and determines whether a detected corner is a blind corner based upon a current position of the vehicle and road data. A blind distance calculator calculates a distance from the determined blind corner to the vehicle based upon the current position of the vehicle and the road data. A necessary engine braking amount calculator calculates, on the basis of a calculated distance, a necessary engine braking amount necessary for decelerating a current vehicle speed to a vehicle speed at which it is possible to stop around the blind corner when a braking operation is performed with a full braking amount. A required speed change stage determinator calculates a required speed change stage based upon the determined necessary engine braking amount. A transmission controller performs a downshift to a determined required speed change stage.

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.

摘要： A control device for an automatic transmission includes a continuously variable transmission mechanism, a torque converter, a target transmission ratio calculation unit, a feedback control unit, and a phase compensation unit. The torque converter has a lock-up clutch. The target transmission ratio calculation unit is configured to calculate a target transmission ratio based on a travelling state. The feedback control unit is configured to perform feedback control based on an actual value indicative of a state of the continuously variable transmission mechanism. The phase compensation unit is configured to perform phase lead compensation of the feedback control based on the travelling state. The phase compensation control unit is configured to halt the phase lead compensation when an unstable travelling state of a vehicle is detected. The phase compensation control unit is further configured to release the lock-up clutch when the phase lead compensation is halted.

摘要： A vehicle control apparatus is configured to execute gear shifting in an automatic transmission, in accordance with at least one selected shifting line, which is selected from among at least one first shifting line and at least one second shifting line, depending on (i) acceleration representative information related to an acceleration representative value representing an acceleration of the vehicle required by an operator of the vehicle and (ii) location information related to a current location of the vehicle, wherein each of the at least one first shifting line is a shifting line stored in a storage device provided in the vehicle, and each of the at least second shifting line is a shifting line in which other-vehicle-related information is reflected. The other-vehicle-related information is information received from an external device located outside the vehicle, and related to other vehicle that is at least one vehicle other than the vehicle.

摘要： An oil pressure control device has a mechanical oil pump (O/P) driven by a motor/generator (MG), an electric oil pump (M/O/P) driven by a sub motor (S/M) and a line pressure regulating valve (104). In a case where a state is changed from a state in which the motor/generator (MG) is stopped and the electric oil pump (M/O/P) is driven to a state in which the motor/generator (MG) is started and the electric oil pump (M/O/P) is stopped, when a total flow amount of a working fluid discharge flow amount of the mechanical oil pump (O/P) and a working fluid discharge flow amount of the electric oil pump (M/O/P) is equal to or greater than a pressure regulation limit flow amount of the pressure regulating valve (104), the working fluid discharge flow amount of the electric oil pump (M/O/P) is decreased.

摘要： A vehicle includes an accelerator pedal moveable across a plurality of predefined positions and a controller programmed to, responsive to the pedal reaching a tip-in position, command a downshift to a downshift gear from an initial gear. A difference between the initial and downshift gears exceeds a number of predefined positions crossed upon moving to the tip-in position when a rate of change of pedal position exceeds a predefined threshold.

摘要： A control apparatus for an automatic transmission includes an ECU. The ECU stores a N−1 speed downshift/a N−2 speed downshift/a N−1 speed upshift/and a hysteresis lines. The hysteresis line is a predetermined distance above the N−1 speed upshift line, and is below the N−2 speed downshift line. The ECU controls the speed of the automatic transmission based on a quantity of state of a vehicle, and the plurality of stored shift lines, and execute, when an N speed is established, a first downshift that changes a speed from the N speed to an N−2 speed, when the quantity of state of the vehicle is in a region above the hysteresis line, after the quantity of state of the vehicle has risen above the N−1 speed downshift line.

摘要： An automatic transmission control device implements a downshift by disengagement of a clutch that is engaged in a gear position before the downshift. It is determined whether an engine state is in a predetermined region in which a change of an engine torque per a change of an accelerator pedal opening is smaller than that in another region, and the engine torque is within a predetermined range, and an engine rotational speed is within a predetermined range. It is determined whether an operating state is in a predetermined state of accelerator operation in which the accelerator pedal opening is larger than a predetermined value, and an accelerator pedal opening change rate has an absolute value smaller than a predetermined value. The downshift is inhibited in response to determination that the engine state is in the predetermined region and the operating state is in the predetermined state of accelerator operation.
