The invention relates to a method for transmitting an actuation signal and a first data signal between a control device and an actuation device of a power semiconductor device. To minimize the expenditure for the operation of the physical transmission channels and the costs for the laying of the physical connection between control device and actuation device, the transmission of the actuation signal and the first data signal between the control device and the actuation device takes place simultaneously and via a common transmission channel, wherein the first data signal is combined with the actuation signal by means of a digital modulation method or coding method. A feedback signal and second data signal are transmitted in the opposite direction. A first coding length is shorter than the interval length of the actuation signal. A second coding length is shorter than the interval length: of the feedback signal.

The present application relates to control systems, clock synchronization methods, controllers, node devices, and vehicles. In one example control system provided in this application, a primary controller directly sends a reference clock signal to at least one node device by using a ring network, and the at least one node device performs timing based on a frequency of the reference clock signal. The reference clock signal is obtained by performing frequency division on a local clock signal of the primary controller.

A first communication device determines that each second communication device in a plurality of second communication devices has respective data to be transmitted to the first communication device. The first communication device transmits a request to the plurality of second communication devices to transmit data to the first communication device simultaneously during a transmit opportunity period of the first communication device. The first communication device receives data transmitted simultaneously by the plurality of second communication devices during the transmit opportunity period of the first communication device.

A method and system for the post-adjustment (i.e., offline) of event timestamps to implement virtual time synchronization amongst detection node clocks. In existing methodologies with the goal of clock synchronization, clocks (and timestamps generated therefrom) are disciplined or adjusted at the recordation time of the events on a detection node (e.g., a switch/router, an Internet-of-Things (IoT) device, a wireless sensor, etc.). However, there is no particular reason for these clocks or timestamps to be accurate during the recordation time, but rather, should be accurate at their use or interpretation time. Further, through these recordation time adjustments, clock drifts and timing errors may be gradually introduced, leading to runaway inaccuracies. The disclosed method and system intentionally avoids the disciplining of clocks at event recordation times on the detection node and, instead, adjusts timestamps during interpretation times, to overcome the aforementioned issues.

A time synchronizer receives UTC (Coordinated Universal Time) time in serial+PPS (Pulse Per Second) format from a GPS (Global Positioning System) device and outputs timestamp data in multiple formats, including: CAN (Controller Area Network), Ethernet, gPTP (generic Precision Time Protocol), and serial+PPS. Multiple data sources receive timestamp data in the multiple formats and each provide data in a unified UTC time base to a sensor-fusion device. The unified UTC time base is based on the timestamp data in the multiple formats output by the time synchronizer. The time synchronizer may perform edge detection for a first transition of an internal clock signal following a transition of the PPS signal received from the GPS device. The internal clock signal may be asynchronous with the PPS signal received from the GPS device. The internal clock signal may have a frequency of 40 MHz.

A synchronization method for at least two sensors, which enables synchronized collection of a sensor value of a slave sensor in relation to a predetermined intended value of a master sensor. Time-dependent measured values of the master sensor are used to determine open parameters of a prediction model, on the basis of which a time associated with a master sensor intended value to be predetermined is extrapolated. When this time is reached, a synchronization signal triggering the recording of a slave sensor value, in particular the recording of a measured value, is transmitted to the at least one slave sensor. Master sensor intended value and slave sensor value are provided as connected value tuple. As a result of continuous collection of measured values by the master sensor, it is possible to form updated extrapolation rules continuously. Predetermined intended values of the master sensor can have, in particular, an equidistant spacing.
