Abstract
To enable operation of an internal combustion engine even without the signals of a phase sensor while nonetheless enabling an emergency driving function in the case of a disturbance of a crankshaft signal acquired by a crankshaft sensor, a cylinder pressure is acquired using a cylinder pressure sensor and it is checked whether the cylinder pressure reaches a prespecifiable threshold value. When the threshold value is reached or exceeded, an angular position associated with the threshold value is inferred. The angular position is then made available for an operation of the internal combustion engine.
