FAULT DETECTION AND DIAGNOSTIC SYSTEM FOR AUTOMOTIVE BATTERY CHARGING SYSTEMS |
摘要 |
<p>An in situ self-diagnostic automotive alternator battery charging system is disclosed. Included are: a battery; voltage regulator sensing battery voltage and generating an excitation signal; and an alternator driven by a vehicle engine provide a rectified electrical signal to charge the battery in response to the excitation signal. Electronic circuit status detectors, variously coupled to the battery, voltage regulator and alternator, maintain a first logic state when a corresponding signal characteristic is within a predetermined range and a second logic state when the corresponding characteristic is outside the predetermined range. Combinatorial logic means respond to a logic state sequence from the detectors to identify predetermined sequences of the logic states resulting in the identification of faults in the charging system. The logic means also provides a warning to the operator of detection of a fault and a display of the location of the fault as occurring in one of the major components of the charging system.</p> |
