    摘要： Disclosed is an electronic controller which calculates the variable amounts of the thrust in a primary pulley based on the thrusts of the pulleys, the lower limit thrust and the upper limit thrust in the steps of a target change gear ratio limit routine. The electronic controller calculates the limit transmission speeds based on the variable amounts in the steps, and calculates the guard values for limiting the target change gear ratio based on the limit transmission speeds in the steps. An electronic controller limits the target change gear ratio by the guard values thus calculated, and controls the thrusts of the pulleys by feedback control based on the size of discrepancy of the limited target change gear ratio and the current change gear ratio γ.

    摘要： The invention relates to a controller for a vehicle having installed thereon a drive power source, a transmission, and a torque converter that is equipped with a lockup clutch and is provided between the drive power source and the transmission. The controller includes a detection unit that detects an actual revolution speed of the drive power source, and a control unit that controls the lockup clutch so that a state of the lockup clutch becomes any state from among a disengaged state, an engaged state, and a slip state. When executing a slip control, the control unit compares the actual revolution speed with the target revolution speed, and feedback controls a transmission torque of the lockup clutch on the basis of a comparison result of the actual revolution speed and a target revolution speed so as to cause the actual revolution speed to follow the target revolution speed.

    摘要： When a rotational speed of a secondary pulley is less than a first reference value, the disclosed electronic control device implements lower limit hydraulic control to adjust the hydraulic pressure of a primary pulley to be at a lower limit hydraulic pressure. When the rotational speed is equal to or exceeds the first reference value, but is less than a second reference value, the electronic control device implements balanced hydraulic control to adjust the hydraulic pressure to be more than the lower limit hydraulic pressure. When the rotational speed is equal to or exceeds the second reference value, the electronic control device implements feedback control to correct the hydraulic pressure on the basis of the size of the difference between a target transmission gear ratio and a transmission gear ratio, calculated on the basis of rotational speeds detected by each rotational speed sensor.
