A ENGINE CONTROL UNIT (ECU) AND METHOD FOR ADAPTING THE ECU TO PULSE WHEEL IRREGULARITIES

摘要

The various embodiments of the present invention provide an ECU 100 and a method for conforming to irregularities of a pulser wheel 110. The ECU 100 is configured to detect a tooth 120 and a corresponding tooth number using a position sensor 102 and to set a time range for the detection of a subsequent tooth 120 using data from a table that stores the dimensions of the pulse generator wheel 110. The table is stored in a storage element of the ECU 100. The present invention strengthens the ECU 100 or the engine position management system (EPMS) to prevent errors due to such irregularities and rather adapts to the profile of each tooth 120 of the pulse generator wheel 110. An error in the plausibility check of the position sensor 102 is also avoided due to irregularities in the pulse generator wheel 110.
