3. A motor vehicle, comprising:
an internal combustion engine;
a fuel tank that stores a fuel, which is to be combusted by the internal combustion engine;
an accumulator unit that accumulates electrical energy therein;
a measurement unit that measures a state of charge of the accumulator unit;
a pressure regulation mechanism that receives a supply of electrical energy from the accumulator unit and regulates an internal pressure of the fuel tank with the received supply of electrical energy; and
a pressure regulation control module that controls the regulation of the internal pressure of the fuel tank by the pressure regulation mechanism, based on the state of charge of the accumulator unit measured by the measurement unit on a start of or in the course of the pressure regulation by the pressure regulation mechanism.
