Abstract
The invention concerns a method for detecting a transition (') in a noisy signal, which involves submitting a noisy signal (δSignal) carrying an item of information used for managing the power steering, said method comprising a derivation sub-step (a), which involves evaluating the time derivative of the noisy signal (δSignal/δt), following by a selective filtering sub-step (a) which involves comparing said time derivative of the noisy signal (δSignal/δt) with a predefined variation threshold (S) in order to detect the appearance of a derivative peak (), greater than said variation threshold (Spic), evaluating the holding time (dpic) of said derivative peak, during which the time derivative of the noisy signal (δSignal/δt) is held above said variation threshold (Spic), and checking if said peak holding time (Spic) reaches or exceeds a predefined minimum time threshold (d).
