Abstract: A system for providing torque assist in a vehicle includes a hydrostatic transmission that is associated with otherwise unpowered wheels of the vehicle. Operation of the hydrostatic transmission can be commanded by a controller based on sensor inputs, indicative of wheel speeds of each wheel present in the vehicle, to provide torque to the otherwise unpowered wheels of the vehicle. Moreover, when torque difference exists between one wheel and another from the otherwise unpowered wheels, the controller can independently and selectively actuate one or more pumps that are included in the hydrostatic transmission so that each wheel from the set of otherwise unpowered wheels rotates at the same wheel speed.

Abstract: An idle reduction engine shutdown and restart system for a machine is disclosed. The machine can include an engine operably connected to a drivetrain including ground engaging propulsion members. The drivetrain can be configured to transmit mechanical energy between the engine and the ground engaging propulsion members. The idle reduction engine shutdown and restart system for the machine can include a starter operatively associated with the engine and configured to effectuate ignition of the engine. The idle reduction engine shutdown and restart system for the machine can further include an idle reduction engine shutdown and restart controller electronically and controllably connected to the engine and configured to shut down the engine in an engine shutdown mode. The idle reduction engine shutdown and restart controller can additionally be electronically and controllably connected and configured to actuate the engine and the starter to start the engine in one or more of an initial engine start mode and one or more engine restart modes.
