  "textContent": "A method for operating an internal combustion engine of a drivetrain of a vehicle during launching. The vehicle has an exhaust-gas aftertreatment system for purifying exhaust gas of the engine. After a starting operation of the engine, the drivetrain is operated in a first operating state. In this first operating state, the engine is operated at idle, the exhaust-gas aftertreatment system is heated by the internal combustion engine, and a launch prohibition is active. The launch prohibition that is active in the first operating state prevents launching using the internal combustion engine. After a predefined state of the exhaust-gas aftertreatment system has been attained, the drivetrain is operated in a second operating state. The launch prohibition is inactive in the second operating state, such that launching using the engine is possible in the second operating state.",
