Abstract: A system and method provide seamless control switchover through an input coupled to a power line and a safety apparatus that actuates if the input remains de-energized for a first time interval. Each of a plurality of subsystems has a control unit that controls a power source to energize the power line and is capable of transitioning between master and slave states. A first switch or second and third switches in series couple the power source to the power line. The first switch is closed during master state operation. The second switch is closed during slave operation and the third switch is open if any subsystem control unit is in master state. The system is configured to open or close the first switch, the second switch, or the third switch responsive to a transition of a control unit to or from master state within the first time interval.

Abstract: A method of common controller area network (CAN) bus traffic supervision on a system having a common CAN bus, a first CAN chip and a second CAN chip, the first CAN chip and the second CAN chip are coupled together with the common CAN bus, the method includes comparing a first CAN frame received from the first CAN chip to a second CAN frame received from the second CAN chip within a CAN comparison period, and detecting a failure of at least the first CAN chip or the second CAN chip. Detecting the failure of at least the first CAN chip or the second CAN chip includes determining that the first CAN frame is not identical to the second CAN frame within the CAN comparison period.
