摘要：In a vehicle having a voltage regulated electric alternator (14') driven by anengine (31) for supplying power to drive electrical loads (18') and to charge a vehiclebattery (10'), a method of maintaining state of charge of the battery includes adaptivelylearning a system voltage set-point during a first mode of engine operation resulting inan electrical system operative in set-point regulation. The method determines from thelearned system voltage set-point and a current system voltage during a second mode ofengine operation that the electrical system is operating in an auto-regulation mode. Idlespeed is controlled in response to the regulation state of the electrical system tomaintain the system in set-point regulation so as to ensure adequate battery charge orminimal battery discharge during the second mode of engine operation.
