Control device and control method for continuously variable transmission |
摘要 |
A transmission controller determines whether an oi1 temperature in the CVT is higher than a high oil temperature control starting temperature or not. If it is determined that the oil temperature is higher than the high oil temperature control starting temperature, a first oil temperature lowering processing which limits an input rotation speed of the CVT by changing a speed ratio of the CVT smaller is executed. If the input rotation speed of the CVT reaches a predetermined lower limit rotation speed during execution of the first oil temperature lowering processing, the first oil temperature lowering processing is ended and a second oil temperature lowering processing that limits a torque of an engine is executed. |
