摘要： An apparatus for ratio control of a continuously variable transmission includes a driver commanded ratio unit outputting a signal defining a commanded ratio. A clamp control portion is in communication with the driver commanded ratio unit. The clamp control portion includes: a ratio limits and override ring selecting a ratio matching the commanded ratio from an executable functions having stored ratio code data; a screening monitor continuously receiving output from the executable functions and using an input from a vehicle speed signal to compute minimum and maximum ratio limits for the ratio selected by the ratio limits and override ring; and a ratio control execution ring in communication with the screening monitor. The ratio control execution ring calculates a range of pressures allowed for operation of both primary and secondary pulleys of the continuously variable transmission.

摘要： A continuously variable transmission (CVT) (14) includes a drive pulley (18), a driven pulley (20), and an endless rotatable device (22) coupled between the drive and driven pulleys (18, 20). The drive pulley (18) and the driven pulley (20) each include pulley teeth (19T, 21T), and the endless rotatable device (22) includes device teeth (22T). A controller (50) can control the operation of the CVT and can execute the following instructions: (a) receiving a torque request while the device teeth (22T) are mating with the pulley teeth (19T, 21T); (b) determining whether the torque request direction is opposite to the input torque direction; (c) determining whether a current clamping force applied by an actuator (28, 30) to the drive pulley (18) is sufficient to change the direction of the torque transmitted by the drive pulley (18); and (d) commanding the actuator (28; 30) to increase the current clamping force when the current clamping force is not sufficient to change the direction of the torque transmitted by the drive pulley (18).

摘要： When a line pressure is dominated (determined) by at least one of a primary pressure and a secondary pressure during idling of a continuously variable transmission, the hydraulic pressure that is applied to at least one of pulleys, to which the hydraulic pressure larger than a clutch pressure is applied, is reduced. On the other hand, when the line pressure is dominated by the clutch pressure during idling of the continuously variable transmission, the speed gear ratio of the continuously variable transmission is controlled to a lowest speed gear ratio.
