    摘要: A system for the just-in time scheduling of camshaft timing for an internal combustion engine. A slave circuit generates an execution period corresponding to the execution period of the variable camshaft timing mechanisms. The control processor initiates the calculation of a correction signal base on the difference between the desired camshaft timing and the actual camshaft timing synchronous with the execution period of the variable camshaft timing mechanism. The calculation of the correction signal is executed by the central processing unit once and only once for each execution period of the variable camshaft timing mechanism.
