Abstract (en)

The invention relates to an electronic device for determining the angular position of a driving shaft (3) in internal combustion engines (2), of the type intended to cooperate with an engine electronic control unit (ECU) and receiving an input signal emitted by a sensor (8) of a tone wheel (7) associated to the driving shaft (3). <??>Said device (1) has the task of calculating the angular position of the driving shaft by analysing the signal transmitted by the tone wheel of the driving shaft, thereby releasing the engine electronic control unit (ECU) from the monitoring of the driving shaft angular position to reduce its computational load and allow to treate the signal transmitted by a plurality of tone wheels highly widespread in the automotive field. <IMAGE>
