摘要： Systems and methods for efficiently and effectively controlling the rate of change of ratio, not simply the ratio, in a CVT. By controlling the rate of change of ratio, the acceleration or deceleration of a vehicle can be controlled in an efficient manner. Furthermore, the rate of change of ratio can be controlled by controlling the clamping pressure of the pulleys and/or differential pressure between the pulleys with minimal slip by using a servo control mechanism adapted for control by a system controller based on equilibrium mapping and other control parameters.

摘要： A belt-type continuously variable transmission changes winding radii of a belt that is wound around an input-side and an output-side pulley to shift speeds. The belt-type continuously variable transmission is mounted on a vehicle that switches between two-wheel drive is transmitted only to front wheels and four-wheel drive. An electronic control unit that controls the belt-type continuously variable transmisson adjusts the belt clamping pressure of each pulley as torque is distributed to the rear wheels, to suppress muffled noise due to resonance of vehicle components with belt span vibrations.

摘要： A vehicle includes an engine-driven oil pump, which is driven by the rotation of an output shaft of an internal combustion engine, a variable valve timing apparatus, which operates based on hydraulic pressure supply provided by the oil pump, and a continuously variable transmission capable of continuously varying the transmission gear ratio. An electronic control unit sets the transmission gear ratio of the continuously variable transmission based on the operating state of the vehicle. The electronic control unit changes the transmission gear ratio, which is set based on the operating state of the vehicle, in such a manner that the engine speed is increased when the hydraulic pressure supply via the hydraulic oil provided from the oil pump to the variable valve timing apparatus is low.

摘要： In a vehicular belt-driven continuously variable transmission, belt squeezing force is inhibited from becoming excessive and a safety factor, with respect to belt slip, of belt squeezing force applied to a transmission belt (48) is reduced to a value that is less than or equal to 1.5 by reducing a pressure receiving area (SOUT) of an output side hydraulic cylinder (46c). As a result, a centrifugal hydraulic pressure canceller chamber on a secondary pulley side (46) can be eliminated thus simplifying the structure of the vehicular belt-driven continuously variable transmission, while belt squeezing force can be appropriately controlled.

The hydraulic pressure control system includes a line pressure control means for controlling a line pressure supplied to one of the variable pulleys; and a speed ratio control pressure control means for controlling the line pressure as a speed ratio change pressure supplied to the other of the variable pulley according to a desired speed ratio.

摘要： A process for presuming a power-transmitted state in a metal belt-type continuously variable transmission and for controlling axial thrust in a metal belt-type continuously variable transmission wherein it is presumed that a vector sum of friction coefficients .mu..sub.TDN and .mu..sub.RDN of a driven pulley is 0.1; a friction coefficient .mu..sub.RDR of a drive pulley is 0, and a friction coefficient .mu..sub.SDR or .mu..sub.SDN of the one of the pulleys which has a smaller winding radius is 0.1. A speed ratio i, a number N.sub.IN of rotations of the drive pulley, an input torque T.sub.IN to the drive pulley and an axial thrust Q.sub.DN of the driven pulley are measured, and the measured values are introduced into relational equations of the balance of forces on various portions of a metal belt-type continuously variable transmission. In this manner, an axial thrust Q.sub.DR of the drive pulley, urging forces E.sub.1 and E.sub.2 between the blocks and the pulleys, an axis-axis force FS, ring tensions T.sub.1 and T.sub.2, a friction coefficient .mu..sub.TDR, a friction coefficient .mu..sub.TDN, a friction coefficient .mu..sub.RDN, and a friction coefficient .mu..sub.SDR or .mu..sub.SDN of the one of the pulleys which has a larger winding diameter can be calculated from the relational equations. Thus, a power-transmitted state such as the friction coefficient can be presumed without actual generation of a slipping between a metal belt and a pulley of the metal belt-type continuously variable transmission.

摘要： A continuously variable V-belt transmission includes a lateral pressure control valve for controlling the lateral pressures of a drive pulley and a driven pulley, and a controller for controlling the lateral pressure control valve. The controller calculates a target belt transmission torque by adding a predetermined marginal torque to a transmission torque calculated based on a signal detected from a driving condition of a vehicle, and obtains, by means of a signal converter, a control signal for controlling the lateral pressure control valve. With this arrangement, it becomes possible to prevent slippage between the belt and pulleys and to produce a most appropriate clamping force even when the lateral pressure control oil pressure is varied due to secular and environmental changes in the pulley lateral pressure control valve, whereby the transmission is rendered durable, efficient in fuel consumption and highly reliable.
