Title:
CONTROL DEVICE OF ENGINE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2016079950
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device of an engine for a vehicle which secures sufficient startability while suppressing the generation of noise or the like at a start of the engine.SOLUTION: A control device of an engine for a vehicle comprises: a decompression amount setting part 58 which sets intake valve timing vt_egst at decompression control on the basis of at least either of a crank angle crk_ini which is calculated from a preset relationship by a piston position calculation part 52, and a suction-scheduled air amount m_air which is calculated by a suction-scheduled air amount calculation part 54; and an engine start control part 62 which performs a start control of an engine 12 after the intake valve timing vt_egst is set by the decompression amount setting part 58. Therefore, since a proper decompression amount can be set prior to the start of the engine 12, when the decompression control is performed at the start of the engine, the generation of noise or the like accompanied by the start of the engine can be suitably suppressed without lowering combustion torque more than necessary.SELECTED DRAWING: Figure 1
