Abstract: Provided is an apparatus for controlling a road wheel actuator (RWA) system, the apparatus including a sensor module configured to detect sensing data of at least one of a steering angle, rack position information, angular velocity of a steering wheel, and column torque, and a processor configured to perform a Proportional Integral Differential (PID) control logic based on the sensing data detected by the sensor module and the RWA position information fed back from the RWA system.

Abstract: A charging control device mounted inside an electric vehicle, the charging control device including a communication channel configured to be connected with an EVSE (electric vehicle supply equipment), a controller configured to be connected with the communication channel, and an internal power protection unit connected with a battery of the electric vehicle, wherein the communication channel is based on a protocol of supporting a power line communication (PLC) or a controller area network (CAN), wherein the controller includes a task unit, the task unit operating based on a charging mode of a charging standard.

Abstract: A positive crankcase ventilation (PCV) system includes: an oil separator separating oil from blow-by gases; a PCV valve allowing the blow-by gases from which the oil has been separated by the oil separator to flow into intake ports of a cylinder head; a PCV passage vertically extending from the PCV valve; a PCV chamber connected to the PCV passage; and a plurality of bypass passages branching off from the PCV chamber to the intake ports, respectively.

Abstract: A recirculation valve configured to open or close a recirculation line connected to a front stage of a compressor from a rear stage of the compressor on an intake line of an engine is provided. The valve includes a recirculation valve adaptor that has an inlet into which gas is introduced formed in a bottom thereof, having an outlet from which the gas is discharged formed in a first side of a side surface thereof, and having an inner space connected to the inlet and the outlet and in which the gas flows. A plug is configured to open or close the inlet and the outlet. The inner space has an asymmetric shape in which a width in a horizontal direction is increased in a direction from the other side of an inside surface to one side thereof.

Abstract: A valve device for a vehicle may include a pneumatic valve having first and second chambers in which respective pressures thereof are regulated, and a pressure regulation valve coupled to the pneumatic valve, the pressure regulation valve communicating with the first chamber, including a positive pressure side opening and a negative pressure side opening, and selectively opening and closing the positive pressure side opening and the negative pressure side opening to regulate the pressure in the first chamber.

Abstract: The present disclosure provides an apparatus and a method for reducing rattle noise of an automotive turbocharger. The apparatus and the method may reduce the occurrence of rattle noise, caused by exhaust gas passing through an exhaust bypass hole, by bidirectionally controlling an opening angle of a waste gate valve by an actuator. The actuator may utilize a bidirectional motor so that the waste gate valve may operate in a direction in which the exhaust bypass hole is opened as well as in a direction in which the exhaust bypass hole is closed. Further, the rattle noise can be reduced by a valve stopper which supports the rear side of the waste gate valve in an opened state, the valve stopper is provided at an appropriate position of a turbine housing.

Abstract: An apparatus for operating a recirculation valve for a turbocharged engine includes a bypass line connected between an intake line, which is connected to an inlet side of a compressor for a turbocharger, and an intake line which is connected to an outlet side of the compressor; and a recirculation valve openably and closably mounted in the bypass line. A vacuum pump for operating a brake is connected to the recirculation valve such that the recirculation valve is opened by negative pressure of the vacuum pump.

Abstract: A mobile terminal is capable of updating user presence information in mobile instant messaging. The mobile terminal and associated method facilitate updating user presence information in multiple sessions of mobile instant messaging. The method includes: joining multiple IM communities; issuing a command for presence information update in relation to one of the multiple IM communities; and sending a request for presence information update to IM servers of two or more IM communities including the IM community indicated by the issued update command, among the multiple IM communities.

Abstract: A method and system logging in to an Instant Messenger (IM) a includes: registering login schedule information to an IM server; transmitting, by the IM server, login information to an IM client when a login time included in the login schedule information arrives; and logging in, by the IM client, to the IM server using the login information. A user of the mobile terminal presets the login schedule information so that the mobile terminal may login automatically to an IM community at a preset time. If the user of the mobile terminal forgets to log in at the preset time, the mobile terminal may log in to the IM community automatically.
