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 comprises: a target state of charge setting part configured to set a target battery state of charge; and a running control part configured to 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, wherein the running control part is configured to switch a running mode of the hybrid vehicle between an electric vehicle, EV, mode and a hybrid vehicle, HV, mode wherein in the EV mode, the rotating electrical machine is driven by the electrical power stored in the battery and wherein in the HV mode the rotating electrical machine is driven by the power of the internal combustion engine, and the target state of charge setting part is further configured to 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 target battery state of charge is a mode switching state of charge wherein the running control part is configured to switch the running mode from the HV mode to the EV mode when a state of charge of the battery is greater than or equal to the mode switching state of charge and is configured to switch the running mode from the EV mode to the HV mode when the state of charge of the battery is less than the mode switching state of charge. an internal combustion engine;
