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.
Claims16
A method of controlling a starter/alternator in an I.C. engine, comprising the steps of:
- detecting a temperature of a first component of said I.C. engine and obtaining a first detected temperature;
- comparing said first detected temperature with a predetermined acceptable temperature;
- and,
- disabling said starter/alternator when said detected temperature exceeds said predetermined acceptable temperature.
