Abstract
A method for controlling a pulley of a vehicle having a continuously variable transmission may include: determining, by a controller, a pulley target torque and a target pulley ratio, upon detecting disturbance of the vehicle; determining, by the controller, target pressures of a driving pulley and a driven pulley based on the pulley target torque and the target pulley ratio and comparing the target pressures with each other; and controlling, by the controller, a pressure of a pulley having a larger target pressure in the comparing to be a maximum pressure generatable depending on a traveling situation of the vehicle and controlling a pressure of the other pulley to be increased to a correction pressure for implementing the target pulley ratio.
Claims10
A method for controlling a driving pulley and a driven pulley of a vehicle having a continuously variable transmission, the method comprising:
- determining, by a controller, a pulley target torque and a target pulley ratio, upon detecting disturbance of the vehicle;
- determining, by the controller, target pressures of the driving pulley and the driven pulley based on the pulley target torque and the target pulley ratio and comparing, by the controller, the target pressures with each other;
- and
- controlling, by the controller, a pressure of a either one having a larger target pressure among the driving pulley and the driven pulley in the comparing to be a maximum pressure and controlling, by the controller, a pressure of another one among the driving pulley and the driven pulley to be increased to a correction pressure for implementing the target pulley ratio.
