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： Disclosed is an integrated control method for an engine and a transmission, which is capable of integrally controlling the engine and the transmission, based on a control correlation between the engine and the transmission. This method determines a target engine operating point reflecting a driving state of a vehicle and a driver's intention to accelerate, in an integrated control map having an engine control area and a transmission control area. The method calculates a target shift ratio based on the target engine operating point, thus being capable of significantly saving a man-hour required to set a map as compared to a conventional control method in which an engine torque map and a shift pattern map are individually set, and improving fuel efficiency.

摘要： A working machine having a belt-type continuously variable transmission in a working power transmission system includes a target working speed setting section for optionally setting a target working rotational speed of a working unit, a working unit speed sensor that detects an actual working rotational speed of the working unit, a speed reduction ratio regulation mechanism that regulates a minimum speed reduction ratio of a rotational speed of a driven pulley with respect to a drive pulley, and a control unit. The control unit controls a drive source rotational speed to bring the actual working rotational speed close to the target working rotational speed, obtains a minimum limit speed reduction ratio based upon a target minimum rotational speed of a drive source and the target working rotational speed, and controls the speed reduction ratio regulation mechanism to keep the minimum limit speed reduction ratio.

摘要： A vehicle driving device includes an engine, a continuously variable transmission, and a controller. The controller controls the engine and the continuously variable transmission such that an operating point determined by a rotation number and an output torque of the engine follows at least one operating line. In a region where the rotation number of the engine is smaller than a predetermined value, the operating line is set on an optimum fuel efficiency line. In a region where the rotation number equals to or larger than a predetermined value an increasing amount of the output torque relative to an increasing amount of the rotation number in the operating line is larger than the increasing amount of the output torque relative to the increasing amount of the rotation number in the optimum fuel efficiency line.

摘要： A vehicle control device for controlling a vehicle including an oil pump driven by a transmission of a rotation of the motor-generator; and a hydraulic pressure supply unit for supplying a hydraulic pressure to the continuously variable transmission. The hydraulic pressure is generated by regulating a pressure of an oil discharged from the oil pump. When a regenerative braking is performed by the motor-generator based on a deceleration request from a driver, the hydraulic pressure supply unit supplies a hydraulic pressure based on a first hydraulic pressure and a second hydraulic pressure to the continuously variable transmission. The first hydraulic pressure is a hydraulic pressure to transmit an input torque input to the continuously variable transmission during the regenerative braking. The second hydraulic pressure is a hydraulic pressure to shift the continuously variable transmission during the regenerative braking. During the regenerative braking, the first hydraulic pressure is set to equal to or less than a hydraulic pressure found by subtracting the second hydraulic pressure from a hydraulic pressure suppliable to the continuously variable transmission.
