Provided are a message processing method, an apparatus, an electronic control unit, and a readable storage medium. The method includes configuring different sending times for any two different electronic control units corresponding to the same message ID in sending time configuration information of electronic control units; and when sending messages to a CAN bus, sending, by the electronic control units, the messages to the CAN bus at available sending times according to corresponding sending time configuration information, so that the time for any two different electronic control units corresponding to the same message ID to send messages to the CAN bus is separated. The method can improve the safety of the unmanned system.

A user station for a serial bus system and a method for transmitting a message in a serial bus system. The user station includes a communication control device for transmitting messages to a bus of the bus system and/or for receiving messages from the bus of the bus system, and a bit rate switchover unit for switching over a bit rate of the messages from a first bit rate in a first communication phase to a second bit rate for a second communication phase. The bit rate switching unit is designed to switch the bit rate from the first bit rate over to the second bit rate, due to an edge of a predetermined bit sequence that includes one bit of the first communication phase and one bit of the second communication phase.

A teaching data preparation device includes: an acquisition unit configured to acquire a plurality of sensor values from a plurality of sensors; a calculation unit configured to use a sensor value included in the sensor values to calculate a calculation value corresponding to a sensor value other than the used sensor value; a determination unit configured to determine whether each of the sensors is normal; and a teaching data preparation unit configured to prepare, when the determination unit determines that at least one of the sensors is not normal, teaching data from an input-output dataset including at least one calculation value that corresponds to the sensor value of the sensor determined to be not normal.

A subscriber station for a serial bus system and a method for communication. The subscriber station has a communication control device controlling a communication of the subscriber station with at least one other subscriber station of the bus system and generating a transmit signal. The communication control device generates the transmit signal according to a frame and to insert a field having a rising edge and a subsequent falling edge into the frame for the transition from a first communication phase to a second communication phase. The field has a predetermined length between the rising edge and the subsequent falling edge such that a sampling time at which a communication control device of the at least one other subscriber station of the bus system will sample the first bit of the second communication phase is situated between the rising edge and the subsequent falling edge.

Two or more modules communicate over a common control network including receiving by a message packet having data defined by a signal level at defined bit quanta of a bit, the defined bit quanta being less than every bit quanta of a bit, and the communication device samples bit quanta other than the defined bit quanta. The module receives signal disturbances and decodes the signal disturbances as having a value different from an expected value of the certain bit. In another form, the module uses a first counter based on a clock local to the communication device and a second counter having a higher sampling rate than the first counter. Here, the module receives over the control network a synchronizing portion of a message and counts clock ticks of the second counter over a portion of the message to determine a clock rate for a module that transmitted the message.

Embodiments relate to including information in a data packet transmitted by a transmitting integrated circuit (e.g., SOC) to account for a time delay associated with an unsuccessful arbitration attempt to send the data packet over a multi-drop bus. The unsuccessful arbitration attempt by the integrated circuit may delay the transmission of the data packet until the multi-drop bus becomes available for the integrated circuit to send the data packet. The data packet includes a data field to include time delay information caused by the unsuccessful arbitration attempt. A receiving integrated circuit may determine the time that the data packet would have been sent out from the transmitting integrated circuit absent the unsuccessful arbitration attempt based on the delay information. Embodiments also relate to a synchronization generator circuit in an integrated circuit that generates timing signals indicating times at which periodic events occur at another integrated circuit.

A communication system comprising: a digital serial bus, and a master device and at least one slave device connected to the bus. The master and the slave(s) are adapted to communicate according to a predefined communication protocol. The master is adapted for transmitting a continuous bitstream in the form of a plurality of frames, such that each frame comprises one or more words. Each word has a constant time duration, with the first word of each frame being a unique word transmitted by the master for indicating the start of a frame. One or more bits each word is transmitted by the master as a dominant bit; a non-dominant bit, for allowing the at least one slave to overwrite. The at least one slave is adapted for overwriting in the continuous bitstream some non-dominant bits to transmit data in a quasi-synchronous manner.

The present disclosure relates to a method of monitoring Local Interconnect Network (LIN) nodes and a monitoring device performing the method. In an aspect a method of a monitoring device of monitoring a plurality of LIN buses is provided, wherein at least one LIN node is connected to each LIN bus, said plurality of LIN buses being interconnected via the monitoring device. The method comprises detecting, for each LIN bus, any dominant data being sent over said each LIN bus by a LIN node connected to said each LIN bus and routing said any dominant data received by the monitoring device over said each LIN bus to all remaining LIN buses without overwriting any dominant data sent over the remaining LIN buses.

An embodiment method comprises receiving at least one frame comprising consecutive bits transported by a serial bus; estimating an arrival period of a last bit of the consecutive bits; and starting a sending of an acknowledgement of receipt before the end of the estimated arrival period.

The transmission of a recessive bit in a CAN message from a transmitting electronic control unit (ECU) is detected, over a controller area network. A dominant pulse is injected onto the network after a delay time into the detected recessive bit. Behavior of the transmitting ECU is detected, and a sample point for the transmitting ECU is characterized based upon the detected ECU behavior. An action signal is generated based upon the characterized sample point.
