    摘要: The method of the present invention provides a variety of vehicle performance characteristics depending on the mode of operation. A first routine is initiated to provide an optimal balance of powertrain responsiveness and fuel economy for any given combination of vehicle speed and deceleration rate. The first routine may, according to a preferred embodiment, include a plurality of routines that are each configured to provide an optimal balance of powertrain responsiveness and fuel economy within a predefined range of vehicle speeds and deceleration rates. A second routine is initiated if said deceleration rate is within a predefined range. The second routine includes running the electric motor/generator while the hybrid vehicle is being stopped in order to control the driveline lash and thereby minimize disturbances during a subsequent engine re-start.

    摘要: A method of modifying the charging target for the state-of-charge (SOC) of a hybrid vehicle battery in response to a sudden power draw includes determining that the hybrid vehicle has entered a steep grade environment, adjusting a power management scheme of the hybrid vehicle from a standard charging mode to an aggressive charging mode, and operating the hybrid vehicle operated using the adjusted power management scheme. The charging target may include both an immediate charging target and an ultimate charging target, where the immediate charging target is less than the ultimate charging target, and where adjusting a power management scheme from a standard charging mode to an aggressive charging mode includes increasing the immediate charging target.
