Methods and systems for operating actuator control electronics are described. In an example, a system can include a first lane and a second lane configured to be in communication with each other. The first lane can receive first data associated with a first pattern and send the first pattern to the second lane. The second lane can receive second data associated with a second pattern and send the second pattern to the first lane. The first and second lanes can each compare the first pattern with the second pattern. Based on the comparison, the first lane can select first input data and the second lane can select second input data. The first lane can generate a first actuator command using the first input data. The second lane can generate a second actuator command using the second input data. The first and second actuator commands can be bit-for-bit identical.

Data coherency algorithm to achieve bit-for-bit transmission

Remote electronic units effective to generate output data for an actuator are described. A remote electronic unit may include first, second, and third lanes. The first, second, and third lanes may receive input data including an actuator command. The first, second, and third lanes may generate first, second, and third output data, respectively, based on the input data. The first, second, and third lanes may respectively send the first, second, and third output data to a voter. The first and second lanes may respectively send the first and second output data to a multiplexer. The voter may output a selection signal to the multiplexer if at least two out of the first, second, and third output data are identical. The multiplexer may select one of the first and the second output data based on the selection signal and transmit the selection to the actuator via an actuator control electronics.

Three lane bit-for-bit remote electronic unit

A plurality of control channels each include a power supply, an interface that receives a manipulation signal, an arithmetic processing portion that calculates and generates an operation command signal for actuators based on the manipulation signal, and a signal determination unit that determines a control signal for finally controlling the operation of the actuators and outputs the control signal. The arithmetic processing portions respectively provided in the plurality of control channels have designs different from one another. Each of the signal determination units determines the control signal by receiving a first operation command signal generated by the arithmetic processing portion of the control channel in which that signal determination unit is provided, and a second operation command signal generated in the arithmetic processing portion of another of the control channels, and comparing the first operation command signal and the second operation command signal, and outputs the control signal.
