    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: A refresh control system that selectively initiates a refresh charge cycle includes an energy storage device and an electric machine that is operable to charge the energy storage device. A control module monitors a usage period of the energy storage device and determines a bias factor. The control module determines a modified usage period threshold based on a usage period threshold and the bias factor. The control module regulates the electric machine to initiate a refresh charge cycle of the energy storage device when the usage period exceeds the modified usage period threshold.

    摘要: A vehicle control system reduces vehicle rollback upon brake release. The control system includes a brake system, a vehicle grade measurement device and a controller that modulates applied brake pressure of the brake system based on a grade measurement of the grade measurement device. The controller actuates brake-hold device communicating with the brake system based on the grade measurement through pulse width modulation. The control system communicates with a motor generator and an engine to provide a start power to the engine upon brake release based on the grade measurement. Fuel injectors of the engine are enabled upon brake release based on the grade measurement. The control system further communicates with a transmission forward clutch to provide selective rotational communication between the transmission and the engine based on the grade measurement.

    摘要: An automated method for controlling a vehicle having an engine and a transmission includes sensing knock activity in the engine. A transmission ratio applicable to the transmission is selected based on the sensed knock activity. This method allows a vehicle to be operated in a fuel-efficient manner while knock-sensitive operating conditions are avoided.
