ABSTRACT:
A vehicle hill hold may be accomplished, for a vehicle having an automated clutch between the engine output and the transmission input, while protecting the clutch from potential excess wear due to overheating. A hill hold may be accomplished by automatically switching the torque holding the vehicle in place from the clutch to the brakes. Alternatively, a hill hold may be accomplished by increasing an accelerator pedal position sensitivity and switching the clutch between fully engaged and fully disengaged based on changes in the pedal position.
