Abstract: A method of operating a pump/motor includes pumping working fluid into a high-pressure manifold with a first piston/cylinder assembly while the piston in the first piston/cylinder assembly is displaced from a bottom dead center position to a top dead center position, and transferring working fluid from the high-pressure manifold to the cylinder of a second piston/cylinder assembly to displace the piston of the second piston/cylinder assembly from a top dead center position to a bottom dead center position, thereby imparting torque on a cam and an output shaft, within the same complete revolution of the cam and the output shaft in which working fluid is pumped into the high-pressure manifold by the first piston/cylinder assembly.

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 increasing an accelerator pedal position sensitivity and switching the clutch between fully engaged and fully disengaged based on changes in the pedal position.

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.
