Method for controlling slip of a continuously variable transmission

摘要

Disclosed herein is a method for controlling slip of a continuously variable transmission using a transmission control unit (TCU), comprising: receiving, by a transmission control unit, information related to determination of slip which occurs during vehicle's running; calculating a slip determining coefficient by the transmission control unit; determining, by the transmission control unit, whether the slip has occurred according to the slip determining information and a predefined slip determining algorithm; and selecting and switching to, by the transmission control unit, one of a plurality of preset slip modes based on the slip determining coefficient and a result obtained by determining whether the slip has occurred.

1. A method for controlling slip of a continuously variable transmission (CVT) using a transmission control unit (TCU), comprising:
receiving, by the transmission control unit, information related to determination of slip which occurs during vehicle's running (hereinafter referred to as “slip determining information”); calculating a slip determining coefficient by the transmission control unit; determining, by the transmission control unit, whether the slip has occurred, based on the slip determining information and a predefined slip determining algorithm; and selecting and switching to, by the transmission control unit, one of a plurality of preset slip modes based on the slip determining coefficient and a result obtained by determining whether the slip has occurred, wherein the slip determining coefficient is calculated by using differentiated values of rotation speeds of a primary pulley and a secondary pulley, and a gear ratio of a variator.
