Abstract: A relief pressure controlling device comprises a driving side relief pressure controlling valve, a capacity detector which detects the capacity of a hydraulic pump, and an engine throttle opening detector. When the hydraulic pump and the hydraulic motor which are connected by a first oil passage and a second oil passage constituting a hydraulic closed circuit are driven by an engine, the relief pressure controlling valve controls the relief pressure of the oil passage on the driving side that is either the first oil passage or the second oil passage whose pressure becomes higher than the other, to a target relief pressure. The target relief pressure is determined in correspondence with the engine output and corrected on the basis of the pump efficiency which is predetermined in relation to the capacity of the hydraulic pump and to the throttle opening, and this corrected target relief pressure is set as a driving side target relief pressure.

If the deceleration of the vehicle is greater than a standard deceleration when the operation of the brake is detected, then the pressure of the first or second oil passage whose pressure is higher than that of the other is lowered to a predetermined low pressure that is higher than the pressure of either oil passage which is lower by either the first or second pressure controlling means.

Abstract: In order to achieve a gear ratio control of a continuously variable transmission, a transmission gear ratio is controlled based on a difference between an actual engine speed and a target engine speed to be set in response to a first parameter corresponding to an accelerator opening. When controlling the transmission gear ratio, a plurality of change characteristics of the transmission gear ratio are set for, in particular, the kickdown gear shifting. In response to a second parameter representing the driver's demand for a traveling condition, a change characteristic of the transmission gear ratio is selected from among the plurality of change characteristics of the transmission gear ratio, to execute the speed ratio control in accordance with the thus selected change characteristic of the transmission gear ratio when a kickdown gear shifting is needed.
