Method of controlling an automotive charging system in response to transient electrical loads

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