摘要：A speed change control unit of an automatic transmission for automobilesincluding a hydraulic servo for achieving speed change operations electrically andhydraulically controlled depending upon the operating state of an engine. The flow rateof working oil for the servo having a substantially constant pressure applied thereto andflowing through an orifice is detected so as to control the operating speed of thehydraulic servo in accordance with the flow rate, whereby changes in the characteristics ofthe hydraulic servo ascribable to the temperature change and quality fluctuation of theworking oil of the transmission can be thereby compensated for so as to ensure asmooth speed change operation at all times.
