Abstract

See full text

A method of operating a driveline including a powersplit transmission is provided. The driveline may be operated in a hydrostatic power transmission mode and a blended hydrostatic/mechanical power transmission mode. The method comprises the steps of providing a hydrostatic circuit, detecting a rapid deceleration of the vehicle, and adjusting a threshold of at least one pressure relief valve forming a portion of the hydrostatic circuit in response to the sudden deceleration. The at least one pressure relief valve facilitates quickly changing the driveline from the blended hydrostatic/mechanical power transmission mode to the hydrostatic power transmission mode.
