    摘要： A method and system of engine start/stop control for a HEV that monitors the battery and requests a specific engine state based on condition of the battery. A battery parameter such as discharge power limit (DPL) or state of charge (SOC) is compared with a set of threshold levels including a MIN level, an ON level, and an OFF level and the result of the comparison provides inputs to a state machine. The state machine includes an ON state, an OFF state and a OPPORTUNISTIC state. The machine transitions between the various states as a function of DPL and SOC relative to the sets of threshold levels.

    摘要： A method for restarting an engine in a hybrid electric powertrain includes using an auxiliary pump while the engine is shutdown to maintain stroke pressure in an oncoming transmission friction control element whose engagement is required to launch the vehicle following the restart, initiating an automatic engine restart, increasing a torque capacity of the control element while the engine is restarting, and using pressure produced by a transmission pump in the transmission to lock the control element after the engine restarts.

    摘要： An electric vehicle such as a PHEV or a BEV and a method of control includes receiving from a user of the vehicle, at an interface of the vehicle, a distance until charge (DUC) value indicative of the distance from a current position that the vehicle is intended to be driven before the vehicle is recharged. Battery usage of the vehicle is controlled as a function of the DUC value. An initial estimate of the DUC value may be made by obtaining historical distance between charges (DBC) values indicative of the distance the vehicle has been driven between each of one or more pairs of consecutive charges of the vehicle. The estimated DUC value is based on the DBC values.
