1. A hybrid vehicle comprising:
- an internal-combustion engine;
a battery;
an electric motor operated by the battery;
a generator driven by the internal-combustion engine to charge the battery;
a fuel tank configured to supply fuel to the internal-combustion engine;
a measuring instrument that detects an amount of remaining fuel in the fuel tank;
a transmission configured to transmit motive power produced by the internal-combustion engine to wheels of the vehicle via clutches;
a clutch control module configured to control connection and disconnection of the clutches; and
a controller that determines a traveling mode from at least one of a parallel traveling mode for running by setting the clutches in a connected state and transmitting motive power produced by the internal-combustion engine to the wheels of the vehicle and a series traveling mode for running by setting the clutches in a disconnected state, driving the generator by the internal-combustion engine to generate electric power, and, while electric power is generated by the generator, transmitting motive power produced by the electric motor to the wheels of the vehicle,wherein the controller automatically prohibits the parallel traveling mode by setting the clutches in the disconnected state and causes the vehicle to run in the series traveling mode on the condition that the controller determines, based on the detected amount of the remaining fuel, that the amount of the remaining fuel in the fuel tank is less than or equal to a first predetermined amount, andwherein the controller continues the series traveling mode until the fuel in the fuel tank runs out.

Abstract
A hybrid vehicle includes a traveling mode determination module configured to determine a traveling mode at least one of an internal-combustion engine traveling mode for running by transmitting motive power produced by the internal-combustion engine to wheels of the vehicle and an electric motor traveling mode for running by transmitting motive power produced by the electric motor to the wheels of the vehicle. The traveling mode determination module prohibiting the internal-combustion engine traveling mode and causing the vehicle to run in the electric motor traveling mode when the amount of the remaining fuel in the fuel tank is less than or equal to a first predetermined amount.
