摘要: In accordance with an aspect of the present disclosure, an electrical system for an automotive vehicle has an electrical generating machine and a battery. A set point voltage, which sets an output voltage of the electrical generating machine, is set by an electronic control unit (ECU). The ECU selects one of a plurality of control modes for controlling the alternator based on an operating state of the vehicle as determined from vehicle operating parameters. The ECU selects a range for the set point voltage based on the selected control mode and then sets the set point voltage within the range based on feedback parameters for that control mode. In an aspect, the control modes include a trickle charge mode and battery charge current is the feedback parameter and the ECU controls the set point voltage within the range to maintain a predetermined battery charge current.

摘要: A fuel supply system with an accumulator that allows for the accumulation of fuel at a pressure greater than the nominal operating pressure of the fuel supply system. The accumulation of fuel allows for less frequent fuel pump operation and therefore a reduction in overall fuel consumption of an engine.

摘要: Charging control techniques for a vehicle including an engine that drives an alternator configured to charge a battery of the vehicle comprise modeling a fuel consumption of the alternator for each load level across a range of alternator loads using an engine torque model and a set of operating parameters of the engine, determining an energy output from the alternator for each load level across the range of alternator loads, calculating a cost-to-charge metric based on the modeled alternator fuel consumption and the determined alternator energy output for each duty cycle across a range of duty cycles of the alternator, determining an optimal cost-to-charge from the calculated cost-to-charge metrics, determining a target cost-to-charge metric based on a state of charge of the battery, and operating the alternator accordingly at an optimal duty cycle based on the metrics and current engine operating conditions.
