Abstract: A method for executing a driving task in a decentralized control unit system and a decentralized control unit system are provided. The control unit system includes at least two control units that are designed as senders, and at least one control unit that is designed as a receiver. The at least two senders and the at least one receiver in each case have activity states and operating states. The two senders and the receiver in each case check their own activity states. The two senders' own activity states are compared to the receiver's own activity state. An evaluation of operating states is carried out if the two senders' and the receiver's own activity states are in each case error-free. The driving task is executed if one of the two senders and the receiver in each case has a dynamic operating state.

Abstract: A method for the transfer learning of hyperparameters of a machine learning algorithm. The method includes providing a current search space and a previous search space. A reduced search space is then created and candidate configurations are drawn repeatedly at random from the reduced search space and from the current search space, and the machine learning algorithm, parameterized in each case with the candidate configurations, is applied. A Tree Parzen Estimator (TPE) is then created as a function of the candidate solutions and the results of the machine learning algorithm parameterized with the candidate configurations, and the drawing of further candidate configurations from the current search space using the TPE is repeated multiple times, the TPE being updated upon each drawing.

Abstract: A pressure relief valve assembly includes a pressure relief valve having a valve bushing received in a valve bore of a housing bore, and a valve body biased against a valve seat by a spring guided in the valve bushing. The valve body includes first and second control surfaces subjected in an opening direction, respectively, to a pressure to be limited and to a control pressure. A fixing device disposed on the valve bushing axially supports the valve bushing in the housing bore.

Abstract: A hydraulic arrangement includes a hydraulic cylinder and a hydraulic pump for its pressure medium supply, which can be driven by an electric motor of the arrangement and can be fluidically connected to a cylinder chamber via a pressure medium flow path. At least one shutoff valve is provided in the pressure medium flow path, through which the pressure medium flow path can be hydraulically disconnected for load holding of the hydraulic cylinder without drive. An operating variable of the electric motor is determined or detected upon hydraulic disconnection of the pressure medium flow path, and the detected or determined operating variable is set and tracked on the electric motor upon setting a condition at which the pressure medium flow path is opened.
