The controller may be configured to set an operation of a first EV mode using the second motor-generator, a second EV mode using the first and second motor-generators, or a series mode of driving the second motor-generator by using power generation of the engine, compare a speed of the vehicle with a reference speed based on that the engine is in an off state, and may be configured to perform a control so that the vehicle drives in the second EV mode when the speed of the vehicle is less than the reference speed.

Dependencies are inferred from the claim text.
