SYSTEM AND METHOD FOR DETERMINING WHETHER A CVT IS SET TO A MAXIMUM GEAR RATIO AT VEHICLE STARTUP

摘要

A system includes a continuously variable transmission having a primary pulley assembly configured to receive power and a primary oil chamber coupled to the primary pulley assembly such that a pressure of oil within the primary oil chamber is applied to the primary pulley assembly. The continuously variable transmission also includes a secondary pulley assembly and a drive belt configured to transfer power from the primary pulley assembly to the secondary pulley assembly. The system also includes a pressure sensor coupled to the primary oil chamber and configured to detect a pressure of the oil within the primary oil chamber. The system also includes an electronic control unit coupled to the pressure sensor and configured to determine whether the continuously variable transmission is set to the maximum gear ratio based on the detected pressure of the oil within the primary oil chamber.

1. A system for determining whether a transmission of a vehicle is set to a maximum gear ratio during startup comprising:
a continuously variable transmission having a primary pulley assembly configured to receive power and including a primary fixed pulley and a primary sliding pulley, a primary oil chamber coupled to the primary pulley assembly such that pressure of oil within the primary oil chamber is applied to the primary pulley assembly, a secondary pulley assembly including a secondary fixed pulley and a secondary sliding pulley, and a drive belt configured to transfer the power from the primary pulley assembly to the secondary pulley assembly; a pressure sensor coupled to the primary oil chamber and configured to detect a pressure of the oil within the primary oil chamber; and an electronic control unit coupled to the pressure sensor and configured to determine whether the continuously variable transmission is set to the maximum gear ratio based on the detected pressure of the oil within the primary oil chamber.
