摘要： A method for controlling regeneration of a battery includes determining a scaled value for a state of charge of the battery, a scaled value for a battery temperature and a scaled value for a maximum charging power of the battery. An actual battery temperature is then compared with a predetermined operating temperature. When the actual battery temperature is less than the predetermined operating temperature, an actual regeneration amount is calculated based upon the scaled value for the state of charge of the battery and the scaled value for the battery temperature. When the actual battery temperature is greater than the predetermined operating temperature, the actual regeneration amount is based upon the scaled value for the state of charge of the battery, the scaled value for the battery temperature, and the scaled value for the maximum charging power of the battery.

摘要： An anti-rollback control system for a vehicle having a brake system includes a brake pedal that is operable to induce a brake pressure in the brake system and a control module that holds the brake pressure equal to a hold pressure that is based on an incline angle to inhibit rollback of the vehicle when pressure is relieved from the brake pedal. The control module initiates forward propulsion of the vehicle based on a driver input and reduces the brake pressure from the hold pressure concurrent to initiating the forward propulsion.

摘要： An electrical charging strategy and system for a high voltage electrical energy storage system able to supply electrical energy to a hybrid vehicle is disclosed. The system charges the electrical energy storage system so state-of-charge at the end of a trip is substantially unchanged. The strategy and system employs opportunity charging to achieve maximum energy efficiency of the hybrid system, thus minimizing fuel consumption and maximizing fuel economy. The charging system operation is controlled, based upon: the state-of-charge of the electrical energy storage system, and, the operating efficiency of the internal combustion engine. Battery life is likewise extended through use of this strategy.

摘要： Provided is an intake manifold pressure control apparatus, or vacuum pump, for a hybrid propulsion system. The vacuum pump is operable to evacuate the intake manifold of an internal combustion engine, thereby lowering the Manifold Absolute Pressure, or MAP, to a predetermined level to enable a quick restart of the internal combustion engine. This vacuum pump may also be used to evacuate hydrocarbons, or HCs, from within the intake system to prevent evaporative emissions from the intake manifold upon engine shutdown. In the preferred embodiment, the vacuum pump is operated by a motor that can simultaneously operate an auxiliary transmission oil pump. Additionally, the present invention provides a method of controlling the hybrid propulsion system to enable the manifold pressure control apparatus to lower the MAP value within the intake manifold as well as a method of evacuating HCs from the intake manifold upon engine shutdown.
