  Su­perKEKB is the up­grade of KEKB, the asym­met­ric en­ergy elec­tron-positron col­lider for the B-fac­tory ex­per­i­ment in Japan. It aims at the 40-times higher lu­mi­nos­ity than the world record by KEKB. The KEKB con­trol sys­tem has been built based on EPICS at the equip­ment layer and script­ing lan­guages at the op­er­a­tion layer. The Su­perKEKB con­trol sys­tem con­tin­ues to em­ploy these frame­works while we im­ple­ment new fea­tures for the suc­cess­ful op­er­a­tion at such a high lu­mi­nos­ity. As the com­mis­sion­ing of the Su­perKEKB main stor­age rings is sched­uled to start in 2016, the con­struc­tion of the con­trol sys­tem is now in the final phase. We have up­graded and re­in­forced the net­work sys­tem, server com­put­ers and op­er­a­tor con­soles. Most of the VME-based IOCs (I/O Con­trollers), which has been widely used in KEKB, are up­graded while the PLC-based IOCs are also widely in­tro­duced. The new tim­ing sys­tem has been de­vel­oped in order to han­dle the com­pli­cated in­jec­tion scheme of the Su­perKEKB ac­cel­er­a­tor com­plex ef­fi­ciently. The new beam abort trig­ger sys­tem and the new beam gate con­trol sys­tem have been de­vel­oped, and so on. The con­struc­tion sta­tus of the Su­perKEKB ac­cel­er­a­tor con­trol sys­tem will be pre­sented.
