Abstract: A user station for a serial bus system and a method for communication in a serial bus system. The user station includes an application for carrying out a task, a transceiver unit for serially receiving a message in the form of a frame from a bus of the bus system, via which user stations of the bus system exchange messages with one another, and a filter module for filtering the received frame. The filter module for filtering is designed to check at least two segments of the frame separately to determine whether or not the received frame is to be passed on to the application.

Abstract: A server system obtains, for machines in a distributed system, system risk information, such as information identifying open sessions between respective users and respective machines, information identifying vulnerabilities in respective machines; and administrative rights information identifying groups of users having administrative rights to respective machines. The server system determines security risk factors, including risk factors related to lateral movement between logically coupled machines, and generates machine risk assessment values for at least a subset of the machines, based on a weighted combination of the risk factors. A user interface that includes a list of machines, sorted in accordance with the machine risk assessment values is presented to a user.

Abstract: A method for controlling a powertrain includes sensing a change in an accelerator pedal position indicative of a driver intended torque request, monitoring the actual engine torque and a change in driver intended torque request to determine if a trigger condition has been met, sensing an engine speed, calculating a virtual engine speed, calculating a difference between the engine speed and the virtual engine speed, determining if the difference in engine speed and virtual engine speed has exceeded a speed difference threshold, iteratively adjusting a torque output of the engine from a first value that is indicative of the driver intended torque request to a second value if the difference in engine speed and virtual engine speed has exceeded the speed difference threshold, comparing adjusted engine torque to expected torque, and applying a correction to an open loop torque control if adjusted torque differs too much from expected torque.

Abstract: A method for operating an internal combustion engine is described in which a combustion air ratio (?) is determined and used to determine a deviation of this combustion air ratio from an in particular default or determined set point combustion air ratio. Spontaneous ignition of the internal combustion engine are detected based on the determined deviation (??) and used to control the operation of the engine.

Abstract: A method for the fuel consumption reduction and/or power increase of an internal combustion engine of a motor vehicle is disclosed. A crank angle of a crankshaft is detected at which out of a cylinder the exhaust gases of a cylinder can be representatively measured on a lambda probe. The exhaust gas flow is measured on the lambda probe. A signal of the lambda probe is scanned at the time of the detection of the crank angle. A value indicated the detected angle and/or the scanned signal is sent to a computer. The value is corrected with the help of an exhaust gas pressure or exhaust gas back pressure model stored in the computer. An effective combustion lambda of the cylinder is calculated based on the sent values and a global lambda value stored in the computer and used to the control of the internal combustion engine.

Abstract: A method for controlling a motor vehicle with an internal combustion engine and a catalytic converter is disclosed. The method includes: determining an oxygen storage value, which is a dimension for oxygen stored in the catalytic converter, detecting an engine load, carrying out a part evacuation of the oxygen from the catalytic converter with a fuel enrichment when the oxygen storage value exceeds a trigger evacuation threshold value and when the engine load is below a low-load threshold value.
