Disclosed are a method and an apparatus for managing a user profile. A user profile management method performed by a server according to an example embodiment includes creating a plurality of profiles corresponding to a user account, receiving a view request for a profile of the other user account in a predetermined relationship with the user account from a user terminal logged in with the user account, providing a UI of a profile of the other user account including an interfacing object regarding the profile of the user account to the user account, receiving an input for selecting a profile to be displayed on the other user terminal logged in the other user account, among a plurality of profiles corresponding to the user account through the interfacing object, and matching the other user account with the selected profile.

Method and apparatus for managing user profile

A method and apparatus for operating an instant messaging server are disclosed. The method for operating an instant messaging server according to an example embodiment includes managing a message sent and received through a first chat room of a messenger application, managing a message sent and received through a second chat room of a 3party application receiving support a chat function through the instant messaging server, identifying a user account of an instant messaging service (IMS) linked with a user account of the 3party service participating in the second chat room, and providing, based on the identified user account of the IMS, the second chat room of the 3party application to the messenger application.

Method and apparatus for operating instant messaging server

The present disclosure relates to a steering control apparatus and method, and a steering system. The steering controller manages the access right to the shared resource so that the access to the shared resource shared with the other steering controller is not overlapped with the other steering controller by using the shared resource manager, and controls the steering of the vehicle by accessing the shared resource according to the access right to the shared resource.

Steering control apparatus and steering control method and, steering system

The present disclosure relates to a rear-wheel steering system and a controlling method thereof. The rear-wheel steering system includes: a rack configured to transmit a driving force generated from a rear-wheel steering motor to rear wheels; a first correction module configured to, when an engine is started, detect a position of the rack using a displacement sensor and calculate a first correction value that is a difference between the detected position and a neutral position; a second correction module configured to, when the engine is started, detect a position of the rack using a motor position sensor that detects a rotation angle of the rear-wheel steering motor and calculate a second correction value that is a difference between the detected position and the neutral position; a comparison determiner configured to compare the first correction value and the second correction value to determine whether the displacement sensor has malfunctioned; and a steering controller configured to control an operation of the rear-wheel steering motor. Accordingly, it is possible to determine whether an error occurs in the displacement sensor and to return the rack to the neutral position even when the error has occurred in the displacement sensor.

Rear-wheel steering system and controlling method thereof

Disclosed herein is a charger for electric vehicles, which has a wide output voltage range. The charger is a slow charger having an improved configuration to respond to a wide output voltage range as well as output change. The charger may achieve limited switching loss and reduced noise via soft-switching operation, thereby enabling high-efficiency large-power Power Factor Correction (PFC) and increasing conversion efficiency of a DC/DC converter.

Charger for electric vehicle

An electric power steering apparatus including a motor includes: a steering torque sensor; a speed sensor; an auxiliary steering force setting unit configured to output a signal representing a linear change of a gradual increase or decrease; a map setter configured to receive a signal output from the auxiliary steering force setting unit and to set an auxiliary steering force map where a maximum steering torque, a maximum target motor current, or a ratio of a target motor current to a steering torque at a specific speed gradually increases or decreases; a current signal supply configured to output the steering torque signal and a target motor current signal corresponding to the speed signal according to the auxiliary steering force map; and a motor driving unit configured to supply a current corresponding to the target motor current signal to the motor.
