1. A vehicle control device, comprising a processor, wherein the processor is configured to:
cause a vehicle to enter an electric vehicle (EV) priority mode in which an electric motor of a vehicle is prioritized for use as a drive source of the vehicle and an internal combustion engine is not used, when a state of charge (SOC) of a battery configured to supply electrical power to the electric motor is not less than an electric vehicle switch (EV-SW) permissible SOC that is lower than a normal target SOC and an EV switch has been switched ON;
prohibit the vehicle from entering the EV priority mode in a case in which the SOC is less than the EV-SW permissible SOC; and
execute low SOC control to set a particular target SOC, which is a target SOC for when the vehicle, which is traveling from a first specific position along a first journey route, arrives at a second specific position, to a value lower than the normal target SOC,
wherein the particular target SOC of the vehicle executing the low SOC control is equal to or greater than a value of the EV-SW permissible SOC in a case in which a prohibition frequency is a first threshold or greater, the prohibition frequency being derived based on a total value of prohibition points that represent the vehicle being prohibited from entering the EV priority mode as a result of the low SOC control.
