Abstract:
A method for operating a transmission of a machine comprising an engine, the transmission and a brake pedal operated brake, wherein the brake pedal may be positioned in a downshifting mode, braking mode or neutralizer mode, the method comprising:(A) obtaining data relating to brake pedal position, machine velocity, machine engine speed, current transmission operating gear, and lowest operating gear;(B) setting downshifting thresh holds based on whether pedal position is in a downshift mode or a braking mode;(C) downshifting the transmission if the machine velocity and machine engine speed are less than the downshifting thresh holds, and if the transmission operating gear is not the lowest operating gear;(D) neutralizing the transmission if the pedal position is in a neutralizing mode, if the velocity is less than a neutralizing thresh hold velocity, and if the transmission is in the lowest operating gear; and(E) repeating steps (A) through (D) until the transmission is neutralized.
