| 20090299588 | CONTROL DEVICE AND CONTROL METHOD FOR CONTINUOUSLY VARIABLE TRANSMISSION - A gear ratio control unit is provided to set a target gear ratio on the basis of an operating condition of the vehicle. The gear ratio control unit controls a drive amount of a step motor such that an actual gear ratio converges with the target gear ratio, and when a deceleration of the vehicle exceeds a predetermined threshold, controls the gear ratio by controlling the drive amount of the step motor such that a predetermined gear ratio is maintained. The gear ratio control unit determines the predetermined threshold on the basis of the actual gear ratio upon detection of an operation of a brake. | 12-03-2009 |
| 20110015033 | CONTINUOUSLY VARIABLE TRANSMISSION AND CONTROL METHOD THEREOF - The transmission controller performs a non-coordinated shift, in which the gear position of the subtransmission mechanism is modified from the second gear position to the first gear position at a higher speed than when the gear position of the subtransmission mechanism is modified by a coordinated shift while permitting a deviation between the through speed ratio and the target through speed ratio, instead of the coordinated shift when it is determined that the second speed kick down shift is to be performed. | 01-20-2011 |
| 20110015834 | CONTINUOUSLY VARIABLE TRANSMISSION AND CONTROL METHOD THEREOF - When a vehicle stops in a travel range, a transmission controller sets a subtransmission mechanism in a second speed interlocking condition in which a torque input into a continuously variable transmission is transmitted in a second gear position and both a frictional engagement element of a first gear position and a frictional engagement element of the second gear position are engaged, and when a predetermined condition is established while the vehicle is stationary, the transmission controller reduces an output shaft torque of the continuously variable transmission. | 01-20-2011 |
