Abstract: A vehicle-mounted key-generation method is for a vehicle including electronic control units (ECUs) that communicate with each other via a vehicle-mounted network. At least one ECU includes a key generation module and a key transmission module, and each of the other ECUs includes a key receiving module and a key invoking module. The method includes receiving, through at least one ECU, a secure access request sent from an authorized user through a secure access device, and, after confirming to accept the secure access request from the secure access device, waiting for the secure access device to send a key generation request. The method further includes, after receiving the key generation request, generating a key through the key generation module, using the key transmission module to send the key to other ECUs via the vehicle-mounted network, and receiving the key through the key receiving module in other ECUs.

Abstract: A method for identifying and classifying static radar targets with the aid of a radar sensor of a motor vehicle. The method includes: identifying an object as a static radar target based on the received radar signals reflected by the object, generating an occupancy pattern in an occupancy grid based on the received radar signals reflected by the object, storing an assignment, which assigns the generated occupancy pattern to the static radar target, classifying the static radar target as belonging to one or multiple groups of static radar targets based on characteristic features of radar signatures of the received radar signals reflected by the corresponding object. A radar sensor is also described.

Abstract: A handling appliance, in particular a robot, includes at least one handling device that is movable in at least one direction of movement, a collision protection device configured for limiting contact forces due to collisions of the handling device with objects, and an acquisition device. The collision protection device includes a kinematic system that mechanically enables a relative movement of the handling device relative to the carrier of the handling device and that can be inhibited by at least one actuator device. The acquisition device determines forces acting on the actuator device and/or the handling device and on components of the collision protection device decoupled by the actuator device, and the collision protection device accounts for the forces and, via the actuator device, in the absence of a collision prevents, and in the case of a collision triggers and/or enables, relative movement of the handling device relative to the carrier.
Abstract: A method for qualification of a camera system and/or its image/camera signals of a partially autonomously or autonomously driving vehicle. Infrastructure information from a vehicle's surroundings is used. The image/camera signal of the camera system is monitored by a monitoring function with regard to at least the following criteria: image/camera signal in recurring, known time windows, sequence of the image/camera signals, corruption of the image/camera signals, signature checking of the camera system. Checking of the image/camera signals using unmoving land markings that are reconciled with a list is carried out and they are checked for a mapping signature. Then the image/camera signals and the infrastructure information contained in the updated map check function are communicated to an evaluation function and merged and compared in a signal fusion unit. Consequently, a qualified image/camera signal is obtained.
Abstract: A rotary machine, in particular electric motor, includes a position sensing means for sensing a rotational position of a pole wheel that is rotatable about an axis of rotation. The pole wheel has a circumferential edge, and the position sensing means has at least one first position sensor for sensing a change in a magnetic field, at least one magnetic element arranged on the pole wheel, and at least one circuit card on which electronic components are arranged. The first position sensor is arranged at least indirectly on the circuit card. The first position sensor extends at least partially into a space of the pole wheel that surrounded by the circumferential edge.
Abstract: A prechamber spark plug, including center and ground electrodes, a housing having an external thread, a cap arranged on the housing and together with the housing defines a prechamber, and an insulator which electrically insulates the center electrode from the housing. The external thread has a thread length in the axial direction. The housing is fastened to the insulator at first and second fixing regions so that a first clamping force at the first fixing region acts from the housing on the insulator, and a second clamping force at the second fixing region acts from the housing on the insulator. The first and second clamping forces are directed in opposite directions to one another in the axial direction. A distance between the first and second fixing regions in the axial direction defines a clamping length. A ratio between the thread length and the clamping length is between 0.7 to 1.3.

Abstract: A method for predicting a driving maneuver in a driver assistance system of a motor vehicle. Based on dynamic data of the vehicle detected with the aid of sensors, a history of a driving maneuver, which is not yet completed, is recorded and, based on the history, a future course of the driving maneuver is predicted. Multiple hypotheses for potentially occurring driving maneuvers are represented by respective associated sets of parameters. A theoretical history of the driving maneuver is calculated based on the parameters for each hypothesis. The recorded history is compared to at least one of the theoretical histories. Based on a similarity degree, the hypothesis which describes the presently occurring driving maneuver with the highest probability is determined and output as the prediction result.
