Abstract
A system and method for protecting a component of an I.C. engine system by controlling a starter/alternator in response to the component's temperature. The system describes a method of comparing the temperature of the component to a predetermined threshold temperature and, if the temperature exceeds the threshold, disabling the starter/alternator. According to the present invention the temperature of the vehicle battery, starter/alternator motor and starter/alternator inverter may be protected. The starter/alternator is controlled/disabled according to mode of operation.
