Abstract (en)
[origin: DE102005045857B3] The pressure finding process finds the ambient pressure (p amb) by a pressure sensor (40) in the induction manifold (50). During the process, the throttle valve (30) is opened, so that the pressure drop across the throttle (p thr) can be found. The engine is unthrottled by a corresponding adjustment of the camshaft, depending on the operating state of the engine, so that the process is not noticed by the driver.
