Abstract:
1. An electrical load drive control apparatus comprising: a plurality of drive units, each of which drives one of a plurality of electrical loads; an instruction unit that issues a drive switch instruction to switch drive among the plurality of electrical loads; a detection unit that detects a non-operating state of the plurality of electrical loads; and a control unit that controls the plurality of drive units based upon the drive switch instruction issued by the instruction unit and results of a detection by the detection unit, wherein: the control unit controls the plurality of drive units so as to set all of the plurality of electrical loads in a non-operating state if an instruction to switch drive among the plurality of electrical loads is issued by the instruction unit, and controls the plurality of drive units so as to switch drive to an electrical load selected through the drive switch instruction after verifying that the plurality of electrical loads are all set in a non-operating state based upon the results of the detection by the detection unit.
