A line pressure control method for a double clutch transmission (DCT) includes estimating a line pressure, which decreases with stoppage of an electric oil pump, based on a linear regression model using state variables of the DCT that are related to a line pressure change, and driving the electric oil pump when the line pressure estimated based on the linear regression model reaches a predetermined lower limit.

A catalytic converter for a vehicle includes an LNT converter into one side of which exhaust gas discharged from an engine flows and from the opposite side of which the exhaust gas. The LNT converter traps nitrogen oxide contained in the exhaust gas under a lean environment, desorbs the trapped nitrogen oxide under a rich environment, and reduces the nitrogen oxide contained in the exhaust gas or the desorbed nitrogen oxide. A connecting housing changes a direction of a path of the exhaust gas to a vertical direction, and allows a reducing agent to be injected to the exhaust gas. An SDPF converter changes a direction of a path of the exhaust gas to a direction opposite to a direction, captures particulate matters contained in the exhaust gas, and reduces nitrogen oxide contained in the exhaust gas using the injected reducing agent.
