Abstract
A hybrid vehicle includes a battery, a generating unit having an internal combustion engine and a generator which generates electric power by operating the internal combustion engine to supply the generated electric power to a motor or the battery, and the motor which is driven by the electric power supplied from at least one of the battery and the generating unit. A generation control apparatus for the hybrid vehicle evaluates the driving condition of the vehicle from viewpoints of the energy consumption at the motor, the NV performance of the vehicle and the generation efficiency of the generating unit and determines whether or not the operation of the generating unit is necessary based on an evaluation parameter of any one or more viewpoints.
