Processing signals from messages on at least two data buses, particularly CAN buses in a vehicle, includes extracting at least one signal from at least one message in a traffic node of the at least two data buses and at least one extracted signal value of the at least one signal is checked for a change relative to the signal value of the at least one signal that was most recently held in the memory unit. The at least one extracted signal value of the at least one signal is held in the memory unit if the at least one extracted signal value of the at least one signal has changed relative to the signal value of the at least one signal that was most recently held in the memory unit.

A method and an apparatus includes the monitoring of a control device. If a critical event occurs during monitoring of the control device, the control device is transferred () into a safe state, and it is determined whether a problem solution is available for the event that has occurred by way of a parameter modification of the control device in a problem-solving database. If the problem solution is available, a parameter data set is provided. In this regard, the parameter data set includes parameter information relating to a parameter to be modified of the control device. If the parameter information for the control device is valid, the parameter is modified according to the parameter information and the control device is released from the safe state.

Method for modifying safety and/or security-relevant control devices in a motor vehicle

A method for monitoring and modifying motor vehicle functions, includes the following steps: ascertaining an anomalous behavior of a function; transmitting the anomalous behavior to a back end; receiving instructions from the back end, the instructions indicating acute measures to be taken in the motor vehicle in order to adequately react to the anomalous behavior of the function; ascertaining a motor vehicle component which is the cause of the anomalous behavior on the basis of the received instructions; converting the motor vehicle component to a degraded configuration which has a limited functional scope; and if the conversion to the degraded configuration is not possible, converting the motor vehicle component to a safe configuration.

Monitoring and modifying motor vehicle functions in a motor vehicle

For connecting a diagnostic unit to a vehicle controller of a motor vehicle via a network connection, it is provided that, when the connection has been established between the diagnostic unit and the vehicle controller, a check is performed as to whether the diagnostic unit is directly connected to the vehicle controller. The diagnostic unit receives diagnostic data from the vehicle controller only when there is a direct connection.

In a method for transmitting image data from a plurality of cameras in a vehicle, a set of functions is provided, which set of functions comprises a plurality of functions each having a requirement for a respective image setting of at least one of the cameras. If a function is activated, a respective image setting is set for at least one of the cameras on the basis of at least one of the function and a respective predefined desired data rate during image data transmission in order to provide the image data from the respective camera for the respective function.

Method, apparatus, computer program and computer program product for transmitting image data

A method of performing compression of image data for at least one image is described. The method comprises receiving image data of at least a part of the at least one image, encoding the received image data into at least one compressed data block, applying at least one bandwidth limit to the at least one compressed data block, and outputting the at least one bandwidth limited compressed data block to a buffer. The method further comprises dynamically updating the at least one bandwidth limit applied to the at least one compressed data block base at least partly on a fill level of the buffer.

Method and apparatus for performing compression of image data

The invention relates to a method and a device for recording data or for transmitting stimulation data, which are transmitted in Ethernet-based networks of vehicles. A method for recording data is described, wherein the data are transmitted from a transmitting control unit to a receiving control unit of a vehicle via a communication system of the vehicle. The communication system comprises an Ethernet network, wherein the data are conducted from a transmission component to a reception component of the Ethernet network via a transmission path, and wherein the data are to be recorded at a logging component of the Ethernet network, which does not lie on the transmission path. The method comprises the configuration of an intermediate component of the Ethernet network, which lies on the transmission path, to transmit a copy of the data as logging data to the logging component; and the recording of the logging data at the logging component.

A method provides an environmental map for a vehicle, wherein the environmental map represents a section of the environment and includes cells which are each assigned to a subsection of the environment of the vehicle. Each cell is assigned occupancy information which is based on the probability of the presence of an object in the subsection assigned to the cell in question. The vehicle has a group of at least two driver assistance systems which are each configured to adopt an active and an inactive state and which, in the active state require occupancy information concerning sections of the environment which at least do not overlap completely. The method determines the driver assistance system(s) which is(are) in the active state; determines the section of the environment that the environmental map is intended to represent, on the basis of the section(s) about which the driver assistance system(s) in the active state require(s) occupancy information. In particular, the section of the environment that the environmental map is intended to represent includes the section(s) about which the driver assistance system or the driver assistance systems in the active state require(s) occupancy information when in the active state.

Provision of an efficient environmental map for a vehicle

An adaptive network has respective network nodes and network connections between the network nodes, the network nodes each having a transceiver which is coupled with a respective network connection. The respective transceiver is designed for providing a mean error value (MSE_i) which is representative of deviations of a received signal from predefined reference signal values. In a reference operating state of the adaptive network, a respective reference error value (MSE_REF) is determined as a function of the mean error value (MSE_i) provided by the respective transceiver. In at least one predefined operating state of the adaptive network, a respective actual error value (MSE_AV) is determined as a function of the mean error value (MSE_i) provided by the respective transceiver. As a function of the respective reference error value (MSE_REF) and the assigned actual error value (MSE_AV), it is determined whether a fault is present in the respective network connection which is coupled with the respective transceiver.

Method and device for monitoring an adaptive network

A conversion device is designed for converting message units of a first communications protocol, which are received by the conversion device on the input side, to container messages of a second communications protocol. A predefined maximal dwell duration in the conversion device is assigned to each message unit. The conversion device is designed for assigning message units with an identical recipient address received on the input side to a container message for the respective recipient address, and to forward the respective container message when the maximal dwell duration of one of the message units assigned to it has expired or a predefined maximal data volume is assigned to the respective container message, induced by the message units assigned to it.
