A power source control apparatus for parallel and series hybrid vehicles is provided. The power source control apparatus determines a required torque of a power source consisting of a generator-motor and an internal combustion engine based on a parameter indicating an operational mode of the vehicle and interrupts fuel supply to the internal combustion engine in a cycle based on the required torque of the power source so as to minimize a fuel consumption. The power source control apparatus further determines a required torque of the generator-motor based on the required torque of the power source and an output torque of the internal combustion engine to switch an operation mode of the generator-motor between a generator mode and a motor mode so as to compensate for a variation in output of the internal combustion engine during the cyclic fuel cut control.
