摘要： A hybrid power unit of a work machine includes an engine and an energy storage device. The engine includes a crankshaft for driving a load and the crankshaft is attached to an energy storage device via a clutch. The energy storage device can be charged by the engine to store energy, that may be used to provide, when required, a boost to engine performance. The clutch may engage/disengage the energy storage device from the engine and/or control a clutch pressure. The clutch protects the crankshaft from shock loading and can slip to prevent over-torqueing of the crankshaft.

摘要： A transmission for an energy storage and recovery system comprises a variable slip transmission and a clutch arranged to transmit drive while slipping. The level of torque transmitted through the slipping clutch is dependent on the clutch force but is independent of the clutch slip speed. Preferably the clutch is provided by a plurality of clutches connected in parallel in a range extender. When drive is transferred between clutches in parallel, the clutch forces of both clutches are controlled to maintain the total torque transmitted by the clutches. This reduces torque fluctuations at the energy source/sink during clutch transfer. Where there are two slipping clutches in series, one clutch is controlled to provide the required torque and the other clutch is controlled in response to a clutch slip speed. This helps to control the speed of rotation of the mass between the clutches.

摘要： A vehicle includes a powertrain configured to transfer energy to a tire and including both an engine and an electric machine. The vehicle also includes a controller configured to charge a traction battery with torque captured by the electric machine in excess of torque required to maintain the departure. The charging is in response to indication of departure from static friction between the tire and a surface during a line lock tire slip event powered by the engine.

摘要： An engine-driven vehicle includes an energy recovery system (20) for recovering energy under braking of the vehicle. Under predetermined conditions, a controller selectively delivers recovered energy from a storage (24) via device (26) to motor the engine (12) above zero speed (e.g. at or above idle speed), preferably during engine fuel cut. The engine may be motored if the vehicle speed is below a threshold speed with zero torque demand for the vehicle driveline, or when the vehicle has been brought to a stop, for example. The step of delivering recovered energy to motor the engine (12) may be initiated if a door on the vehicle is opened or if a park brake on the vehicle is activated. Auxiliary systems are driven by the engine under influence of energy delivered from the energy recovery system to the engine when the vehicle is at rest. The energy recovery system may include a mechanical flywheel.
