Abstract: PURPOSE: A damper system of a steering column is provided to absorb the impact to be delivered to a steering wheel through a steering shaft by absorbing the vibration of the steering shaft and by converting the electrical energy of the piezoelectric element into the heat energy. CONSTITUTION: A damper system of a steering column comprises a viscous body(12), a piezoelectric element(13) and s resistor(15). The viscous body is inserted to the steering column. One end of the viscous body is connected to a wheel through a steering gear and a tie rod. The other end of the viscous body is attached to a steering shaft(11) which is combined to be into one body rotated with the steering handle. The viscous body absorbs and reduces the vibration of the steering shaft. The piezoelectric element changes the vibration of the steering shaft into the electrical energy. The resistor radiates the electrical energy of the piezoelectric element as the heat energy.

Abstract: A control method for determining deactivation of cylinders is provided to determine a normal deactivation and an abnormal deactivation accurately at the time of deactivating cylinders by a cylinder deactivation system and to verify the cylinder deactivated erroneously when a cylinder is abnormally deactivated. A control method for determining deactivation of cylinders includes a step(S110) of enabling deactivation of cylinders upon determination of cylinder deactivation after obtaining inputs from an ECU(Engine Control Unit), a step(S120) of measuring pressure of an intake manifold through a pressure sensor mounted on the intake manifold, a step(S130) of determining whether a particular cylinder is deactivated normally by comparing a first pressure measured at the intake manifold with a second pressure stored in the ECU as a reference pressure of normal deactivation, and a step(S140) of verifying a cylinder operated erroneously among deactivated cylinders by comparing the first measured pressure with a third pressure stored in the ECU as a reference pressure of abnormal deactivation.

Abstract: A variable valve lift system is provided to determine whether the variable valve lift is normally operated, through the change of MAP(intake Manifold Absolute Pressure) value measured by a MAP sensor. A variable valve lift system includes two valve lift values obtained by changing the direction of oil supplied to a roller finger flower and controlling the height of a cam contacted to the roller finger flower. The variable valve lift system compares a MAP value of the variable valve lift that is measured by a roller MAP sensor with a MAP value of the variable valve lift that is input to an ECU and determines whether the variable valve lift is normally operated.
