Abstract:
A control method for stability of an intermediate phase Continuously Variable Valve Timing (CVVT) system may include comparing an oil temperature of the intermediate phase CVVT system with a predetermined value, and interrupting an operation of controlling the CVVT system when the oil temperature is lower than the predetermined value, comparing an engine RPM with a predetermined value, and interrupting the operation of controlling the CVVT system when the engine RPM is lower than the predetermined value, and comparing an operating current of the CVVT system with a predetermined management value A when the operation of controlling the CVVT system is not interrupted.
