1. A control device for a hybrid vehicle, the hybrid vehicle comprising:
an internal combustion engine;
a battery configured to store electric power generated utilizing power of the internal combustion engine; and
a rotating electrical machine configured to be driven by being supplied with one or both of electric power generated utilizing power of the internal combustion engine or electric power stored in that battery,
wherein the control device is configured to:
set a target battery state of charge;
control the internal combustion engine and rotating electrical machine and charging and discharging of the battery to make the hybrid vehicle run so that the battery state of charge becomes the target state of charge; and
set the target state of charge based on a remaining distance or required time from a current position up to a restricted zone in which operation of the internal combustion engine is restricted and a grace period from a current time to a time at which the restriction of operation of the internal combustion engine in the restricted zone is started;
wherein the control device is further configured to, in response to determining that (i) the current position is inside of the restricted zone and (ii) a destination is outside of the restricted zone, set the target state of charge based on a parameter in a correlative relationship with the battery state of charge required for exiting from inside of the restricted zone to outside of the restricted zone, instead of the remaining distance or the required time, and the grace period.
