Abstract
A hybrid vehicle with an internal-combustion engine and an electric motor has a tank ventilation system that includes a fuel tank and a suction pipe leading from a filtering device, which can be regenerated, to the intake path of the internal-combustion engine. A control device is configured to actuate different valve devices for flushing the filtering device, so that ambient air can be fed to the internal-combustion engine through the filtering device and the suction pipe. In addition, the control device is configured such that, during purely electric operation of the hybrid vehicle, it connects the internal-combustion engine as a function of the loading condition of the filtering device or of the flushing gas concentration.
