Abstract: Technologies and techniques for dynamic fixed pattern correction for an image sensor. A current image and a previous image received in the image sensor is stored and a bias and gain is computed for the current image, wherein the computing includes processing the current image together with a current local average value, the previous image, and a previous local average value. A gain correction value and a bias correction value is generated based on the computing, and the gain correction value and bias correction value are combined with the current image to generate a corrected image. A Bayer image is generated, based on the generated corrected image.

Abstract: A method and system for displaying a warning message to warn of insufficient available drive power for use in an electric vehicle, comprising the steps of a detection of measurement values for determining a latest output of an energy storage device of the electric vehicle via a detection unit, a determination of a latest peak output and/or continuous output of the energy storage device on the basis of the detected measurement values via a processing unit, a comparison of the latest peak output and/or continuous output with a threshold value of the peak output and/or continuous output via the processing unit, a display of a warning message by a display when the peak output and/or continuous output falls below the threshold value, wherein the method is not initiated until an attempt is made to establish driving readiness.

Abstract: A method for charging or discharging a battery system, wherein the battery system comprises at least two battery cells connected in parallel and/or in series, which can only be charged or discharged together. A voltage is controlled as a control variable by a current or a power as a manipulated variable. The current or the power is specified by taking into account a first state of charge-dependent characteristic curve and a second state of charge-dependent characteristic curve. The first state of charge-dependent characteristic curve and the second state of charge-dependent characteristic curve have opposite gradients, at least in sections. An apparatus for charging or discharging a battery system is also provided.

Abstract: Technologies and techniques for laterally controlling a motor vehicle on a road, where a roadway marking assigned to a driver's side of the motor vehicle is assigned to a lane type based on sensor data. The lane type characterizes whether the roadway marking is assigned to an ego lane on which the motor vehicle is to be guided, or whether it is assigned to a neighboring lane adjacent to the ego lane. The roadway marking is also assigned to the lane type, based on swarm data, and the lane type assigned to the roadway marking is established as the lane type that is determined as a function of the swarm data when the sensor lane type and the swarm data lane type diverge. The motor vehicle is laterally controlled as a function of the established lane type of the roadway marking assigned to the driver's side of the motor vehicle.

Abstract: A method for determining a position of electrode sheets in an electrode/separator assembly, the electrode sheets including a substrate and a bilateral coating of the substrate. The electrode sheets comprising at least one first and one second type of electrode sheets. Each electrode sheet is optically imaged, at least in regions, in one or multiple image regions. At least one region of a geometry of the substrate and at least one region of a geometry of the bilateral coating of the substrate is determined, based on the optical image. The electrode sheets are stacked to form an ESA. At least one of the two components of the electrode sheets of the first type is captured in the ESA and at least one of the two components of the electrode sheets of the second type in the ESA is captured in a computed-tomographic image.

Abstract: The disclosure relates to a method for evaluating an electric connection of an electric energy storage device to an onboard electrical system of a vehicle. A voltage converter which is connected to the energy storage device is used to supply at least one component of the onboard electrical system with an output voltage of the voltage converter. The method comprises changing the specified voltage of the voltage converter in a specified time interval, whereby the battery voltage and the battery current of the energy storage device can be influenced, detecting the battery voltage of the energy storage device within the time interval, detecting the battery current of the energy storage device within the time interval, comparing the time curve of the battery voltage and the time curve of the battery current, and evaluating the electric connection on the basis of the compared time curves.

Abstract: The disclosure relates to a method and a driver assistance system for assisted reversing with a vehicle-trailer combination, wherein, initially when it is driven forwards, its forward trajectory is stored and objects arranged laterally next to the forward trajectory are detected. A reversing trajectory, which deviates as little as possible from the driven forward trajectory, is planned. The detected object is classified as a collision object if it lies in the planned reversing trajectory. In such case, a new reversing trajectory that is free of collision objects is generated. The trailer is reversed along the new reversing trajectory. A current deviation of an actual reversing trajectory of the trailer from the new reversing trajectory is thereby determined, and when the current deviation is greater than a permissible limit deviation, the trailer is stopped to allow performing a corrective action. The assisted reversing is resumed after corrective action has been performed.

Abstract: A mobile access system for granting access to a device, particularly a vehicle, is disclosed. The system includes a transmitter unit for wirelessly transmitting an unlock signal, a sensor unit with a gyroscopic sensor for detecting movement, and a control unit connected to the sensor unit. The control unit receives sensor data, recognizes a sequence of movements, checks if it matches a predefined first sequence, and unblocks the system if there is a match, enabling the unlock signal transmission only in the unblocked state. The system may also include an input unit for additional user input and an indication element for user feedback. It can block the system based on a second predefined sequence. A method for granting access using this mobile access system is also described.
