Abstract

A method and device are provided for limiting, in a first operating condition, a motor vehicle internal-combustion engine torque. The operating condition, resulting from an operation of a motor vehicle brake, when the engine torque is simultaneously demanded by a driver's intention indicator, differs from a second operating condition, in which the brake is not operated. The limiting takes place at least partially by way of a controlled reduction of an advance angle efficiency in the first operating condition in comparison to the second operating condition.
