摘要： A method is provided for optimizing the cycling frequency between engine on/off states in a vehicle having a controller and auto start/auto stop functionality. The method includes detecting an engine state cycling event, measuring a plurality of vehicle operating values, and using the controller to optimize the cycling frequency via at least one of: automatically adjusting an interval between an auto start event and an auto stop event when each of a first set of the vehicle operating values exceeds a corresponding threshold, and temporarily inhibiting the auto start/auto stop functionality when any value in a second set of the vehicle operating values falls outside of a hysteresis band created around the second set. A vehicle includes an engine and a controller having an algorithm for optimizing the cycling frequency between engine on/off states as set forth above.

摘要： A method controls an amount of time required to commence transmitting torque of an internal combustion engine equipped with a stop/start feature to a transmission configured to transmit the torque of the engine to drive-wheels in a vehicle. The method includes determining whether a start of the engine is likely. The method also includes pre-filling with fluid a hydraulically-actuated clutch that is configured to connect the engine to the transmission when the start of the engine is likely. Accordingly, the amount of time required to commence transmitting torque of the engine to the transmission is reduced. A system employs the method for controlling an amount of time required to commence transmitting torque of the engine.

摘要： In a hybrid-electric vehicle that includes a cabin, methods and systems are provided for modifying a first curve for engine coolant temperature (ECT) warm-up trajectory. The system includes a processor configured to execute software instructions, and a memory configured to store software instructions accessible by the processor. In one embodiment, the software instructions comprise an offset lookup table that is configured to generate, based on a calculated thermal power loss across a heater core and an ambient air temperature, an offset value for modifying the first curve for ECT warm-up trajectory to produce a desired curve for ECT warm-up trajectory that is offset from the first curve. The desired curve for ECT warm up trajectory is used to adjust temperature in the cabin so that fuel consumption can be reduced.
