摘要： A control device for a vehicle having: an engine; and a variator arranged downstream of the engine in a power transmission path connecting the engine and drive wheels, 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 vertical direction (radial direction) during stopping of the vehicle. After starting the low standby control, the controller releases an output limit of the engine based on an actual secondary pressure of the variator.

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.

摘要： An acceleration method for a hybrid drivetrain includes providing the hybrid drivetrain, setting an initial torque transmission ratio of a belt-drive transmission to a lower transmission ratio, and opening a first disconnect clutch to interrupt torque transmission between an internal combustion engine and an electric machine. The method also includes receiving an acceleration command, shifting the torque transmission ratio with a transmission adjustment gradient from the lower transmission ratio towards an upper transmission ratio, increasing a rotor speed of a rotor shaft of the electric machine with a rotor shaft adjustment gradient, and engaging a first disconnect clutch to rotate an ICE shaft to start the internal combustion engine and increase a rotational speed of the ICE shaft towards a current rotor speed.

摘要： A method for controlling an internal combustion engine of a vehicle having a continuously variable transmission is disclosed. When a driven pulley speed is less than a predetermined driven pulley speed and an actual engine speed is less than an engine speed causing a driving pulley speed to be a driving pulley engagement speed: controlling the engine to increase the actual engine speed to increase the driving pulley speed to be at least the driving pulley engagement speed. When the driven pulley speed is above the predetermined driven pulley speed, the actual engine speed is greater than the engine speed causing the driving pulley speed to be the driving pulley engagement speed, and the desired engine speed is less than the engine speed causing the driving pulley speed to be the driving pulley engagement speed: controlling the engine to operate under conditions corresponding to an engine braking speed.

摘要： A control apparatus for a vehicle drive-force transmitting apparatus that includes a gear mechanism and a continuously-variable transmission mechanism. The control apparatus determines whether there is a lower-gear-ratio setting request requesting a target gear ratio of the continuously-variable transmission mechanism to be set to a lower gear ratio that is lower than a highest gear ratio of the continuously-variable transmission mechanism. When it is determined that there is not a detection accuracy of a rotational speed of an output rotary member of the drive-force transmitting apparatus, the control apparatus sets the target gear ratio to the lower gear ratio if it is determined that there is the lower-gear-ratio setting request, and sets the target gear ratio to the highest gear ratio if it is determined that there is not the lower-gear-ratio setting request.

摘要： For a hybrid vehicle including an engine, a motor generator, and a belt-type continuously variable transmission, a controller performs a low speed position return expediting control in response to a downshift request accompanying deceleration. During the low speed position return expediting control, the controller increases a differential pressure between a primary pressure and a secondary pressure and cause a downshift toward a lowest speed position transmission ratio by reducing the primary pressure, and further reduces the primary pressure when the secondary pressure becomes greater than or equal to a trigger threshold value during the downshift; and terminates the low speed position return expediting control when an actual secondary pressure decreases to a secondary pressure minimum level. The controller further sets a secondary pressure lower limit higher than the secondary pressure minimum level during the low speed position return expediting control.
