Method of and device for operating a vacuum accumulator of an internal combustion engine, provided for servo function |
摘要 |
A method of operating an internal combustion engine of a motor vehicle provided with a vacuum accumulator which provides an auxiliary energy required for at least one servo function of the internal combustion engine in form of a vacuum and which is acted upon by a vacuum acting in a suction pipe of the internal combustion engine. The method computes a pressure acting in the vacuum accumulator, supplies mass flows to the vacuum accumulator when at least one servo function is performed, and withdraws the mass flows from the vacuum accumulator when a pressure acting in the suction pipe is smaller than the pressure acting in the vacuum accumulator. The pressure acting in the vacuum accumulator is computed from a mass balance of the mass flows supplied to the vacuum accumulator and withdrawn from the vacuum accumulator.
