CONTINUOUSLY VARIABLE TRANSMISSION AND CONTROL METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To reduce shock in reduction of output shaft torque of a continuously variable transmission during stop of a vehicle. SOLUTION: When a vehicle stops in a travel range, a transmission controller 12 sets a subtransmission mechanism 30 in a second speed interlocking condition in which a torque input into the continuously variable transmission 4 is transmitted in a second gear position and both a frictional engagement element of a first gear position (Low brake 32) and a frictional engagement element of the second gear position (High clutch 33) 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 4.
