Control apparatus and method of continuously variable transmission |
摘要 |
An apparatus and a method control a continuously variable transmission of a motor vehicle which includes a power transmitting member for power transmission by use of friction. A controller of the apparatus detects slippage of the power transmitting member in a predetermined period of running of the vehicle, and increases a clamping pressure that is applied to the power transmitting member when slippage of the power transmitting member is detected. The controller also stores a state of increase of the clamping pressure in a memory, and increases the clamping pressure applied to the power transmitting member in accordance with a previous state of increase of the clamping pressure that was stored in the memory in a previous period of operation of the vehicle.
