1. A hybrid vehicle, comprising:
an internal combustion engine drive, which comprises at least one internal combustion engine;
an electromotive drive, which comprises at least one electric motor and one storage battery,
wherein the storage battery is chargeable both by the internal combustion engine and by an external electrical grid;
at least one electronic control unit; and
an automatically lockable cover of a fuel tank,
wherein the electronic control unit is configured such that, when at least one defined condition that indicates insufficient use of the electromotive drive in relation to the internal combustion engine drive is present, a first coercive measure is implemented in a first coercive measure stage to influence a behavior of the driver toward increased use of the electromotive drive, wherein the first coercive measure is reducing available drive performance of the hybrid vehicle, and
wherein, a second coercive measure is implemented in response to no recharging of the storage battery with energy from the external electrical grid having been performed in the first coercive measure stage, wherein the second coercive measure is keeping the automatically lockable cover of a fuel tank locked until the storage battery has been fully recharged,
wherein a notification of the first coercive measure and the second coercive measure is displayed via a display to the driver, and
wherein implementation of the second coercive measure of locking the automatically lockable cover of the fuel tank is manually deactivated via the display and an operator control unit to allow the driver to manually override the lock of the automatically lockable cover of the fuel tank, wherein the at least one defined condition that indicates insufficient use of the electromotive drive in relation to the internal combustion engine drive remains present after manually overriding the lock of the automatically lockable cover of the fuel tank.
