ABSTRACT:
A control system controls an alternator driven by an internal combustion engine, for generating electric power. A changeover switch selectively switches the destination of electric power generated by the alternator to a plurality of electric load groups having respective different load voltage values, each electric load group having at least one electric load. An ECU controls switching operation of the changeover switch and changes output voltage from the alternator between a plurality of different predetermined voltage values corresponding, respectively, to the plurality of electric load groups, according to a direction in which the changeover switch has been switched. When switching of the changeover switch has occurred, the output voltage from the alternator to be supplied to one of the plurality of electric load groups to which the destination of electric power generated by the alternator has been switched is controlled by the ECU in a manner such that the output voltage progressively changes to one of the plurality of different predetermined voltage values corresponding to the one of the plurality of electric load groups.
