Filling condition detection method for hydraulic switching element in autombile with automatic gearbox uses measurement of induction currents in proportional magnetic armatures

摘要

The filling condition detection method detects the time point of the complete filling of the hydraulic switching element, using measurement of the induction current in the armatures of proportional magnets, obtained upon rapid return movement of a slider of a pressure regulator for the switching element, with calculation of the filling time for the latter.
