  • Patent number: 11236687
    Abstract: An internal combustion engine for a motor vehicle includes a combustion chamber with a gas exchange valve which is movable between an open position and a first closed position. The gas exchange valve is movable on its path from the open position in a direction of the first closed position into an intermediate position located between the open position and the first closed position and is holdable in the intermediate position at least during a part of a compression cycle of the combustion chamber following the open position of the gas exchange valve and is movable into a second closed position following the intermediate position. The part comprises more than a half of the compression cycle and less than a whole of the compression cycle. The gas exchange valve is an inlet valve via which the combustion chamber is supplyable at least with air.

  • Publication number: 20220030014
    Abstract: A method and system for detecting intrusion in a distributed field bus of a vehicle network involve using an Intrusion Detection System (IDS) to detect intrusion in the network. In a network with a number of nodes, IDS is configured in each of the number of nodes. The IDS, in a first node configured in a transmission mode, receives at least one message signal. A hash function is performed on at least one message signal for generating a first Honeypot (HPT) signal. Simultaneously, the first node transmits the first HPT signal to the second node. The first node and the second node generates a reference HPT and second HPT respectively using an echo-hash function. The IDS detect intrusion based on a comparison of the reference HPT and the second HPT. The method is independent of network traffic timing and can be performed in real-time.

  • Patent number: 11230170
    Abstract: A motor vehicle has an interior which is accessible via a door opening which can be closed by a door and which can be enlarged from a driving position into a parking position by displacing a vehicle roof region delimiting the door opening. The vehicle roof region can be moved along as part of the at least substantially entire vehicle roof which can be displaced between the driving position and the parking position relative to a lower vehicle body part. The door is mounted on the displaceable vehicle roof.

  • Patent number: 11220295
    Abstract: A bodywork structure for a passenger vehicle includes a bodywork shell construction with two longitudinal girders and a flexible crossmember device attached to the two longitudinal girders. The flexible crossmember device has a first flexible crossmember and two energy absorption elements where the two energy absorption elements are respectively fixed to the two longitudinal girders and the first flexible crossmember is connected to the two longitudinal girders via the two energy absorption elements. A support framework is disposed between the two longitudinal girders and has a second flexible crossmember that is at least indirectly connected to the two longitudinal girders and is convexly curved in a direction of the first flexible crossmember. The support framework has a load divider disposed between the first flexible crossmember and the second flexible crossmember in the longitudinal direction of the passenger vehicle and extending in the transverse direction of the passenger vehicle.

  • Publication number: 20220004786
    Abstract: A method for evaluating a functionality of a camera arrangement including a pair of cameras using a control unit includes determining a first switching state of a light signal system based on a first measurement data from a first camera of the pair of cameras, and determining a second switching state of the light signal system based on a second measurement data from a second camera of the pair of cameras. The method evaluates the functionality of the camera arrangement based on the first switching state and the second switching state.

  • Publication number: 20210394760
    Abstract: A method for conducting a motor vehicle in an at least partially automated manner includes generating and outputting a plurality of approach signals for controlling a transverse and/or a longitudinal conduction of the motor vehicle in order to conduct the motor vehicle in at least a partially automated manner in such a way that the motor vehicle approaches a traffic junction. The method includes receiving a plurality of environmental signals which represent an environment of the motor vehicle while it approaches the traffic junction. The method determines, based on the environmental signals that the motor vehicle may continue to further approach the traffic junction, must stop, and/or must retreat. The method generates and outputs control signals for controlling the transverse and/or longitudinal conduction of the motor vehicle in order to conduct the motor vehicle in at least a partially automated manner according to the determining process.

  • Publication number: 20210388741
    Abstract: An internal combustion engine for a motor vehicle includes a crankshaft, a camshaft, a cylinder, a piston movably disposed in the cylinder and coupled to the crankshaft for driving the crankshaft, a first gas exchange valve which is assigned to the cylinder, a first valve clearance compensation device, where via the first valve clearance compensation device the first gas exchange valve is displaceable between a first open position and a first closed position by a first cam of the camshaft, and a control unit. The control unit is configured to align the camshaft such that the first valve clearance compensation device is pressure-loaded in the idle state of the crankshaft by a plateau area assigned to the first cam to hold the first gas exchange valve in the first open position.

  • Patent number: 11181049
    Abstract: A method for operating an internal combustion engine having a cylinder, an intake valve, an air pipe, and a valve element disposed in the air pipe, includes detecting a signal for causing a fuel supply of the cylinder to switch off. The valve element is moved out of a first position into a second position triggering a lower flow cross-section while the fuel supply is still activated, where a first cam for actuating the intake valve is allocated to the intake valve. While the fuel supply is still activated, switching from the first cam to a second cam and via the second cam the intake valve is actuated such that the intake valve causes a reduced air intake. An exhaust cam shaft for actuating an exhaust valve is set in an advance direction such that a valve intersection of the intake valve and of the exhaust valve ceases.
