ABSTRACT:
A system for controlling a multiple cylinder internal combustion engine with electromagnetic valve actuation, comprising of at least one cylinder with an engine cylinder valve, a second controller operably coupled to the engine cylinder valve, said second controller configured to adjust at least one of the valve opening and closing timing of the engine cylinder valve, and a first controller connected with the second controller over a first link and a second link, wherein the first controller is configured to send an engine position indication signal to the second controller over the first link and receive a status signal from the second controller over the second link, and wherein the first controller outputs a synchronization degradation signal responsive to a synchronization error between the engine position indication signal and the status signal.
