Abstract
A method of operating a generator in a vehicle is provided, which generator is driven by an internal-combustion engine and supplies energy to a vehicle wiring system. For improving vehicle emissions, particularly after a cold start of the internal-combustion engine, the generator is not operated immediately after the starting operation but is operated only after a defined time period such that it supplies energy to the vehicle wiring system.
