发明名称 Shift control apparatus of belt type continuously variable transmission
摘要 A shift control apparatus of a belt type continuously variable transmission is comprised of a controller which is arranged to set a first hydraulic pressure controlled variable based on a first target transmission ratio determined based on a vehicle traveling condition, to set a second hydraulic controlled variable based on a second target transmission ratio determined based on a predetermined transfer characteristic, to steplessly control the transmission ratio by controlling hydraulic pressures of primary and secondary pulleys hydraulic based on the first and second hydraulic pressure controlled variables, to detect at least one of the hydraulic pressures of the primary and secondary pulleys, and to correct the second target transmission ratio based on the detected hydraulic pressure.
