    摘要: The invention relates to a smart actuator for actuating a clutch having a communication interface for connecting to a higher-level control unit, and at least one data line for connecting to the higher-level control unit, where the smart actuator is configured to identify errors in the higher-level control unit and/or an assigned second smart actuator, and where the smart actuator has controlling means that are suitable for converting the controlled system into a safe system state in the case of a recognized error. Furthermore, the invention relates to a corresponding control method and a control system in which the smart actuators and the method are used.

    摘要: A hydraulic control device that controls a hydraulic pressure to be supplied to a hydraulic servo for a hydraulically driven friction engagement element in an automatic transmission that changes between shift speeds by switching an engagement state of the friction engagement element. The control device configured with a switching mechanism that allows communication between oil passage for a first pressure regulation mechanism and the oil passage for a hydraulic servo and blocking communication between an oil passage for the second pressure regulation mechanism and the oil passage for the hydraulic servo when the signal pressure is not input to the signal pressure input oil passage, and blocking communication between the oil passage for the first pressure regulation mechanism and the oil passage for the hydraulic servo and allowing communication between the oil passage for the second pressure regulation mechanism.
