International Classification:

H02P 910

US Classification:

322 59

Abstract:

A method of regulating voltage output from an alternator of a vehicle charging system is provided in response to transient alternator loads during idle speed operating conditions. The method comprises the steps of: (a) delivering a first alternator field control signal to the alternator; (b) detecting an impulse electrical load based on a variation in battery voltage; and (c) gradually increasing the alternator field control signal duty-cycle over a time period, such that the time period is based on the magnitude of the alternator field control signal duty-cycle, with respect to a maximum alternator field control signal duty-cycle, and based on the engine rotational speed of the vehicle, thereby regulating voltage output and torque load of the alternator. More specifically, the variation in battery voltage is the difference between a measured battery voltage and an average delta battery voltage, where the average delta battery voltage is indicative of the change in battery voltage over a period in time, and the duty-cycle of the alternator field control signal is incremented by a predefined amount until it reaches a maximum value or until a calculated average battery voltage is substantially equal to a predefined voltage regulator set point value. In addition, the first alternator field control signal is delayed for a preliminary period after the step of detecting a variation in battery voltage to minimize battery voltage drop.

International Classification:

F02B 1300

US Classification:

123575

Abstract:

A method for identifying high driveability index fuel for use in a motor vehicle engine includes the steps of determining an engine rotational speed after the engine has started, measuring an elapsed time required for the engine rotational speed to increase from a predetermined low limit to a predetermined high limit, and identifying high driveability index fuel when the elapsed time is greater than a predetermined time limit.

International Classification:

F02M 5100

US Classification:

123491

Abstract:

A flexible fuel compensation system including a method of hot soak fuel enrichment. The hot soak fuel enrichment method includes checking a plurality of enabling conditions. The method also increments of decrements a hot fuel enrichment multiplier depending on conditions of the vehicle. The hot fuel enrichment multiplier is then used to adjust the amount of fuel being sent to the fuel injectors.

International Classification:

F02D 4108

US Classification:

12333917

Abstract:

A computer-implemented apparatus and method for inferring power steering load and for controlling airflow to an engine of a vehicle having an engine speed. A sensor which is connected to the engine senses the engine speed of the engine. An engine speed reference data table stores at least one engine reference speed, and a reference comparator module which is connected to the sensor and to the reference data table performs a comparison between the sensed engine speed and the engine reference speed. The airflow to the engine is controlled based upon the comparison.

Abstract:

A method of throttle fuel lean-out for an internal combustion engine including the steps of sensing a throttle position of a throttle for the engine with a throttle position sensor, calculating a delta throttle value based on the sensed throttle position, determining whether the engine is in a throttle deceleration condition based on the calculated delta throttle value, linearizing the change in throttle position with respect to absolute throttle position and engine speed if the engine is in a throttle deceleration condition, calculating a throttle deceleration fuel lean-out multiplier value based on the linearized change in throttle position, and applying the calculated throttle deceleration fuel lean-out multiplier value to a fuel pulsewidth value of fuel injectors for the engine and reducing the amount of fuel injected into the engine by the fuel injectors.

Abstract:

Battery management techniques for a vehicle include a set of sensors configured to measure a set of parameters of a battery of the vehicle and a controller configured to control recharging of the battery to a first target state of charge (SOC) corresponding to optimized battery life when a mileage of the vehicle is less than a threshold mileage corresponding to an expected transport period of the vehicle, wherein controlling the recharging of the battery to the first target SOC prevents battery malfunctions and thereby reduces vehicle warranty costs for an original equipment manufacturer (OEM) of the vehicle, and control recharging of the battery to a second target SOC determined by a cost-based optimization technique when the mileage of the vehicle reaches the threshold mileage.
