VARIABLE VALVE TIMING MECHANISM AND METHOD

摘要

An ECU executes a program based on which, when a fuel-supply cutoff control is executed or when a hybrid vehicle travels in a second mode in which the engine is stopped and the hybrid vehicle travels using only the drive power generated by a second MG an intake VVT mechanism is controlled so that a valve phase is brought to the mechanically determined most retarded phase. The phase, which is detected by a cam position sensor, is learned as the most retarded phase.
