Abstract: A failure detection apparatus and method of the MDPS may include a configuration that determines a failure of the MDPS in accordance with a vehicle speed, a steering torque, steering angle, a motor torque, and an estimated yaw rate, and when it is determined that the MDPS breaks down, additionally determines the type of failure.

Abstract: Disclosed are a control system and a control method for fail safety of a motor driven power steering (MDPS). The system may include a straight motion/turning determination module for determining whether a vehicle is in a straight motion or turning based on a steering angle of a steering wheel, a steering torque of the steering wheel and a vehicle speed of the vehicle, a fail determination module for determining whether an MDPS fail occurs based on a steering torque of a driver and a motor torque of the MDPS if the vehicle is in the straight motion, a fail type determination module for determining a type of the MDPS fail using a yaw rate change rate if the MDPS fail occurs, and a yaw rate change rate detection module for inputting the yaw rate change rate to the fail type determination module.

Abstract: A device for controlling restoration of a motor driven power steering (MDPS) system may include a controller configured to control an MDPS system model to output a target steering column speed command corresponding to a restoration control torque command based on a received error between a target steering column speed and an actual steering column speed, and a disturbance observer configured to compensate for a disturbance included in an output of the MDPS system model to provide the disturbance to an output of the controller, in which the output of the MDPS system model may be fed back to an input of the controller.

Abstract: An apparatus and method for controlling volume in a terminal adjust the volume of applications in the terminal without adjusting a main volume of the terminal. The apparatus and method display the relative volume of applications and allow a user to adjust each application's volume. If a user adjusts the volume of an application to be greater than a main volume of the terminal, the application's volume may be set to the main volume of the terminal.

Abstract: The present invention provides a power transmission device for an electric vehicle, which can easily transmit the rotational power of a motor to a wheel axle even when the motor is arranged in a direction perpendicular to the wheel axle in view of the layout. According to the present invention, it is possible to easily transmit the rotational power of the motor to the wheel axle by arranging the motor in a longitudinal direction perpendicular to the wheel axle, such as in the case where the motor cannot be arranged in a lateral direction parallel to the wheel axle in view of the vehicle layout, thereby increasing the degree of freedom for the design of the layout of the electric vehicle.
