Abstract:
1. A method for operating a hybrid vehicle having an internal combustion engine supplied with fuel from a fuel tank and having a regeneratable filter device for taking up fuel vapors from the fuel tank, the hybrid vehicle further having a control unit for implementing an operating strategy for controlling when the hybrid vehicle will be operated in an electric mode and when the internal combustion engine will be operated, the method comprising: sensing completion of a partial or complete refilling of the fuel tank; transmitting a completion of refueling signal to the control unit upon sensing the completion of a partial or complete refilling of the fuel tank; operating the control unit for carrying out a forced start of the internal combustion engine promptly upon receipt of completion of refueling signal that is indicative of the partial or complete refilling of the fuel tank; and operating at least one valve for regenerating the filter device after carrying out the forced start of the internal combustion engine.
