Abstract

A method for controlling an engagement of a lock-up clutch (LUC) of a torque converter of a machine is disclosed. The method includes detecting a pedal tap of a pedal, wherein the pedal tap is detected when the pedal is depressed from a position corresponding to a pedal displacement less than a first threshold displacement to a position corresponding to a pedal displacement greater than a second threshold displacement, and then released to a position corresponding to a pedal displacement less than the first threshold displacement within a threshold time duration. The method further includes causing the LUC to move to the LUC unlocked position if the pedal tap is detected.
