摘要： In a method for determining, whether a crankshaft of a combustion engine rotating forward after a reverse rotation is oscillating or continues the forward movement, when noticing a reverse rotation of the crankshaft, the covered rotational angle during a reverse rotation is detected, an actual threshold is computed by adding the covered rotational angle and a predetermined safety distance. The rotational angle of the crankshaft rotating immediately forward after a reverse rotation is compared to the actual threshold.

摘要： Method for determining the reversal of the direction of engine rotation for internal combustion engines having a crankshaft fitted with a target wheel having teeth, one of which is a long tooth, with a unidirectional crankshaft position sensor delivering a signal used for counting teeth and with an engine management device including a processor and a model of the engine behavior in a stalling phase, including: recording the signal and measuring each time difference between two successive edges of the signal, calculating, on the basis of the model, the time variation of the engine position from the time differences between the edges of the signal, and estimating the stopped position of the engine, wherein the model is a second-order polynomial function of time, and the position of reversal of the direction of rotation is estimated from the calculation of the peak position of this second-order polynomial function.
