Summary: | Disclosed is a pre-load control method for improving the lock-up entry response of a damper clutch. According to an embodiment of the present invention, the pre-load control method for improving the lock-up entry response of a damper clutch comprises: a pre-load logic entry condition determination step of performing a pre-load learning entry condition determination step if a preset criterion is satisfied based on state information of a vehicle if a request for transitioning to a lock-up state of a damper clutch is received while the damper clutch is opened; a pre-load learning entry condition determination step of performing a pre-load learning step if a preset criterion is satisfied based on the state information of the vehicle; a pre-load learning step of calculating a pre-load correction value in the current state of the vehicle; and a target pre-load determination step of summing a preset basic pre-load and the pre-load correction value to determine a target pre-load, and then applying the target pre-load to the damper clutch.
댐퍼클러치 락업 진입 응답성 개선을 위한 예압 제어방법이 개시된다. 본 발명의 실시 예에 따른 댐퍼클러치 락업 진입 응답성 개선을 위한 예압 제어방법은, 댐퍼클러치의 락업(Lock-Up) 진입 응답성을 향상시키기 위한 예압 제어방법으로서, 댐퍼클러치가 오픈(open)된 상태에서, 댐퍼클러치의 락업(Lock-Up) 상태로 천이되기 위한 요청신호를 받은 경우, 차량의 상태정보를 바탕으로 기 설정된 기준을 만족할 경우 예압학습 진입조건 판정단계를 수행하는 예압로직 진입조건 판정단계; 차량의 상태정보를 바탕으로 기 설정된 기준을 만족할 경우 예압 학습단계를 수행하는 예압학습 진입조건 판정단계; 차량의 현재 상태에서 예압 보정치를 계산하는 예압 학습단계; 및 기 설정된 기본 예압과 예압 보정치를 합산하여 목표 예압을 결정한 후, 댐퍼클러치에 적용하는 목표예압 결정단계;를 포함하는 것을 요지로 한다. |
