Abstract: In order to reduce drivetrain component wear and tear, a machine monitors for an impending downshift and automatically slows the machine to a speed that keeps engine rpm below a target engine rpm before the downshift is completed. A controller in the machine determines the current speed of the machine and then slows the machine to a new speed associated with the target rpm in the new gear. The controller may simply apply the brakes to slow the machine to the new speed independently of the process of changing gears or may actively delay the gear change until the new speed is achieved.

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.

Abstract: A transmission system is disclosed for use with a machine. The transmission system may have a first clutch to transfer power in a first direction, a second clutch to transfer power in a second direction, a brake, a sensor to generate a first signal indicative of speed, and an input device to generate a second signal indicative of a desire to shift directions. The transmission system may also have a controller to cause disengagement of the first directional clutch in response to the second signal, and to cause the brake to apply retarding torque. The controller may also be configured to determine an error value based on the second signal and a target transmission system speed, to selectively increase retarding torque when the error value increases, and to selectively transfer retarding torque to the second directional clutch when a value of the second signal is less than a threshold value.

Abstract: A transmission system is disclosed for use with a machine. The transmission system may have a first clutch configured to transfer power in a first direction, a second clutch configured to transfer power in a second direction, a brake, and an interface device configured to generate a first signal indicative of a desire to shift power transfer directions. The transmission system may also have a controller configured to cause disengagement of the first clutch in response to the first signal, to cause the brake to apply a retarding torque to a traction device, and to determine an amount of the retarding torque being applied to the traction device. The controller may also be configured to selectively transfer the retarding torque to the second clutch when a capacity of the second clutch to provide retarding torque is about equal to the amount of the retarding torque being applied by the brake.
