Problems solved by technology

However, a general diesel engine has a problem that the up and down movement of the piston is slow during low-speed running, and thus the intake flow rate is slow and smooth mixing is difficult
[0013] However, unnecessary noise is generated during learning and during opening and closing prior to learning, which causes discomfort experienced by vehicle occupants and the marketability of the vehicle is reduced

Abstract

A learning method for controlling opening or closing of an intake / exhaust valve of a vehicle may include a state determining step determining whether a vehicle state satisfies a learning entry condition, a learning frequency determining step determining whether a learning frequency is less than a preset reference frequency after the vehicle starts, when the vehicle state satisfies the learning entry condition, a change learning step learning an area of an inflow passage of the intake / exhaust valve that is changed due to a deposition of impurities, when the learning frequency while driving is less than the preset reference frequency after the vehicle starts, and an escape condition determining step determining whether the vehicle state satisfies a learning escape condition, after the learning step.

Description

technical field [0001] The present invention relates to a learning control method and a learning control device for opening or closing an intake / exhaust valve of a vehicle, and more particularly to a method capable of preventing noise generated when learning the changing area of ​​an inflow passage of an intake / exhaust valve from avoiding vehicle occupants A learning control method and a learning control device for improving vehicle marketability and discomfort. Background technique [0002] A vehicle to which a diesel engine is applied includes a plurality of intake / exhaust valves. Types of intake / exhaust valves include: Exhaust Gas Recirculation Valve (EGR Valve), Air Control Valve (ACV), Swirl Control Valve (SCV), etc. [0003] Among these, the EGR valve is used in an exhaust gas recirculation (EGR) system that recirculates some exhaust gas to the intake manifold to reduce NOx generated in the exhaust gas at high temperature to control the exhaust gas that is recirculate...
