Speed ratio controller and control method of continuously variable transmission |
摘要 |
A gyration angle phi of a power roller (3) of a toroidal continuously variable transmission (10) is made to vary via a step motor (4) and control valve (5). A controller (61) calculates a feedback control amount v of a step motor (4) so that a real speed ratio i of the transmission (10) coincides with a target speed ratio i*. The controller (61) calculates a command value u by correcting a control value v based on a non-linear relation between the gyration angle phi and the real speed ratio i, and controls the actuator (4) based on the command value u.
