发明名称 CONTROL UNIT AND CONTROL METHOD FOR VARIABLE VALVE TIMING MECHANISM, PROGRAM FOR IMPLEMENTING ITS CONTROL METHOD AND RECORDING MEDIUM ON WHICH ITS PROGRAM IS RECORDED
摘要 PROBLEM TO BE SOLVED: To learn the most retarded phase without deteriorating emission performance. SOLUTION: An ECU executes a program including a step (S102) of controlling an intake VVT mechanism so that a phase changes in a second range of including no most retarded phase when driving an engine (YES in S100), a step (S114) of controlling the intake VVT mechanism so that the phase is brought to the mechanically determined most retarded phase when executing a fuel cut (YES in S110) or when a hybrid car travels in a second traveling mode of using driving force of only an MG 2 in a state of stopping the engine (YES in S112), and a step (S116) of learning a phase detected by a cam position sensor as the most retarded phase.
