A standby current of an arithmetic control unit configured to execute a control operation based on an activation signal generated by an uncertain manual operation is suppressed. A power supply relay configured to supply power to an arithmetic control unit is driven so as to be closed by a power supply switch, to thereby apply drive control to a main electric apparatus, and apply drive control to an auxiliary electric apparatus in accordance with a composite activation signal generated by an activation signal processing unit responding to closing operations of activation command elements even when the power supply switch is opened. As a result, a standby current generated in the activation signal processing unit is greatly suppressed compared with a case in which the arithmetic control unit is intermittently activated.
