Estimating the term…
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.
A method of limiting, in a first operating condition, a motor vehicle internal-combustion engine torque, comprising establishing the first operating condition as a result of a brake operation when the torque is simultaneously demanded by a driver's intention indicator, said first operating condition differing from a second operating condition in which the brake is not operated, and limiting the torque at least partially by a controlled reduction of an advance angle efficiency in the first operating condition in comparison to the second operating condition, the limiting also taking place by limitation of charges of internal-combustion engine combustion chambers.
A motor vehicle internal-combustion engine control device, comprising means for, in a first operating condition, limiting internal-combustion engine torque, said first operating condition, as a result of an operation of a brake when the torque is simultaneously demanded by a driver's intention indicator, differing from a second operating condition in which the brake is not operated, the limiting also taking place by limitation of charges of internal-combustion engine combustion chambers, and means for reducing an advance angle efficiency in the first operating condition in comparison to the second operating condition.
