摘要： A dual mode continuously variable transmission (12) for use with motor vehicles includes a transmission input shaft (28) , a transmission output shaft (30) , and a variator (18) disposed between the transmission input shaft (28) and the transmission output shaft (30) . A mixer gear set (20) is operably disposed between the transmission input shaft (28) and the variator output shaft (50) . A clutching element (16) is operably disposed between the input shaft (28) and the mixer gear set (20) . The variator (18) is configured to continuously vary a ratio of input torque to output torque between the variator shafts responsive to commands from an electronic control unit (92, 94, 96) . The variator input shaft (38) is drivingly connected to the input shaft (28) and the variator output shaft (50) is drivingly connected to the output shaft (31) . The electronic control unit incorporates logic rules by which the clutching element maintains the transmission in a variator-oniy mode of operation in a first vehicle speed range, and maintains the transmission in a power splitting mode of operation in a second vehicle speed range greater than the first vehicle speed range.
