Discussed is a display apparatus including a cover window, at least one first display panel arranged on a rear surface of the cover window, a first printed layer arranged on the rear surface of the cover window around the at least one first display panel, wherein reflected luminance of the first printed layer or a color of the first printed layer on color coordinates is formed within a set range so as to correspond to a first measurement value obtained by measuring reflected luminance of the at least one first display panel or a color of the at least one first display panel on the color coordinates.

Display apparatus

An engine synchronization method may include: detecting teeth numbers of crank teeth installed on a crankshaft based on a pulse signal generated from a crankshaft position sensor; calculating a tooth period between a falling edge and a next falling edge of the pulse signal generated from the crankshaft position sensor and detecting a missing tooth based on the calculated tooth period; determining whether the detected missing tooth is an actual missing tooth based on a tooth number detected at the time of detecting the missing tooth; and performing synchronization control of an engine when it is determined that the detected missing tooth is the actual missing tooth.

Engine synchronization system and control method thereof

Disclosed is to a method for compensating noise of a crank sensor in a vehicle. When noise is applied to a crank sensor, information of a crank is predicted based on information input up to now without canceling engine synchronization. The method for compensating noise of a crank sensor includes: judging an engine stroke based on an ignition angle and, based on amount of compensation determined accordingly, creating virtual information of a crank, when judgment of fault of crank signal occurs discontinuously.

Method for compensating noise of crank sensor

A method for improving engine start performance of a vehicle performing engine synchronization at the time of the engine start may include performing a first synchronization task from an engine stop position stored when the engine stops in immediately previous traveling, and performing the first synchronization task when a crank signal of a crank sensor is first input to an engine position management (EPM) module.

Method for improving engine start performance of vehicle

A method for controlling starting of a vehicle upon a failure of a camshaft position sensor includes performing a fuel injection and ignition at a particular timing for starting an engine of the vehicle; measuring a battery voltage of the vehicle after the performing of the fuel injection and ignition for starting the engine; and when the battery voltage rises over a predetermined value, determining that the fuel injection and the ignition are performed at a normal timing.

Method for controlling starting of vehicle upon failure of camshaft position sensor

An engine control method for preventing an engine of a vehicle from stalling on a sloped road includes steps of: detecting whether a shifting lever is in a neutral stage (N-stage); measuring a vehicle speed and a slope angle of the sloped road, and calculating a load acting on a vehicle body on the sloped road; accelerating an engine a first time to increase an engine RPM so that an engine torque is larger than the load; and accelerating the engine a second time to move the vehicle when the shifting lever enters into a driving gear stage (D-stage).

Engine control method for preventing engine stall for vehicle on sloped road

A starting control method for a vehicle having an engine may include determining, by an ECU, whether engine RPM rises when the engine is started, determining whether combustion-related parts are normal, when the engine RPM does not rise over a starter RPM, determining whether a cam position sensor and a crank position sensor are normal, when it is determined that the combustion-related parts are normal, performing control to offset a recognized crank angle by 360 degrees, when it is determined that the cam position sensor and the crank position sensor are normal, and restarting the engine based on the offset crank angle.
