A control device for a hybrid vehicle which enables an appropriate electrical control based on the usable electrical energy stored in the battery device. In this control device, in step S357, in which it is determined whether the value of an energy storage zone B flag F_ ESZONEB is "1". When the result of the determination is "Yes", the operation proceeds to step S358. In step in step S358, the WOT assist amount lowest coefficient KQBWOASTL, which increases as the use-permission zone PECAPFIB of the state of charge SOC increases, is retrieved from a table. In step in step S359, the WOT assist amount coefficient,KQBWOAST, which increases from the lowest table value KQBWOASTL to a predetermined highest value as the state of charge SOC increases, is retrieved from a table, and a value obtained by multiplying the WOT assist command WOTAST and the WOT assist amount coefficient KQBWOAST retrieved from the table is newly set as the WOT assist command WOTAST.
