2-SPEED TRANSMISSION CLUTCH LEARNING SYSTEM FOR HYBRID VEHICLE AND METHOD THEREOF

摘要

A 2-speed transmission clutch learning method for a hybrid electric vehicle may include detecting whether the 2-speed transmission clutch may be operated through an actuator by driving a motor, learning an open position, a slip position, and a lock-up position of the 2-speed transmission clutch by detecting the amount of driving current and the rotation speed of the motor for the operation of the 2-speed transmission clutch, and storing learning values of the open position, the slip position, and the lock-up position of the 2-speed transmission clutch into a memory area, and controlling the operation of the 2-speed transmission clutch by applying the learning values.

1. A 2-speed transmission 1/2 inside clutch learning system, comprising:
a motor; an actuator connected to a rotary shaft of the motor; and a shift controller operating a 2-speed transmission clutch through the actuator by driving the motor, wherein the shift controller learns and stores an open position, a slip position, and a lock-up position of the 2-speed transmission clutch into a memory area when operating the 2-speed transmission clutch by driving the motor, and controls an operation of the 2-speed transmission clutch by applying the learning values.
