    摘要: A vehicle includes an engine, a power source, and a motor. The power source outputs electrical energy in accordance with an actual state of charge, and the motor generates electrical energy when provided with torque from the engine. A position sensor generates a route signal representing drive cycle data between a present location of the vehicle and a selected destination. A controller determines a reference state of charge of the power source at the present location from the drive cycle data and commands the engine to charge the power source if the actual state of charge is below the reference state of charge determined for the present location. A method includes receiving the selected destination, generating the route signal, determining the reference state of charge from the drive cycle data, and commanding the engine to charge the power source in accordance with the reference state of charge.

    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.

    摘要: An air separator for low flow rate coolant systems which removes air from the liquid coolant thereof. The air separator is a closed canister having a bottom wall, a top wall at a gravitationally high location with respect to the bottom wall, and a sidewall sealingly therebetween. A coolant inlet is at the sidewall, a pump outlet is at the bottom wall and a coolant reservoir outlet is at the top wall. The coolant reservoir outlet is connected to a coolant reservoir gravitationally elevated with respect to the canister. A much larger cross-sectional area per unit length of the canister relative to the piping results in a coolant dwell time in the canister that encourages coolant air bubbles to migrate toward the coolant reservoir.
