Abstract
A method for determining the angle-of-rotation position of a shaft of an internal combustion engine, particularly of a crankshaft, information regarding at least incremental angles of rotation of the shaft and run times for each incremental angle of rotation being registered and stored at least temporarily, the angle-of-rotation position being determined on the basis of information regarding already stored incremental angles of rotation and run times in the event of an absence of information regarding incremental angles of rotation. In addition, the use of a double Hall sensor for registering information in implementing the method, a device for determining the angle-of-rotation position of a shaft of an internal combustion engine, as well as an automatic start-stop system for a motor vehicle.
