Abstract
A control method for adjusting the hydrocarbon concentration in an active carbon filter of a tank ventilation device of a motor vehicle, includes the acts of: detecting an operational parameter of the internal combustion engine of the vehicle; determining the hydrocarbon content of a fuel tank gas mixture in the fuel tank ventilation device; and opening the tank ventilation valve of the tank ventilation device for a defined length of time in accordance with the determined hydrocarbon content when the operational parameter of the internal combustion engine displays an overrun mode or a standstill mode of the internal combustion engine generated by a start-stop system.
