Abstract: An apparatus for determining whether a vehicle is in a stuck state may include: a receiving unit configured for receiving driving information of a vehicle; a score determination unit configured for determining a stuck score based on the driving information; and a stuck determining unit configured for determining whether a vehicle is in a stuck state based on accumulated stuck scores obtained by accumulating stuck scores.

Abstract: An apparatus for estimating a vehicle speed includes: a vehicle information receiving unit for receiving driving information of a vehicle, including wheel speed, motor torque, and longitudinal acceleration of the vehicle; a wheel slip determining unit for determining whether wheel slip occurs; a longitudinal acceleration correction unit correcting the longitudinal acceleration received from the vehicle information receiving unit; and a vehicle speed estimation unit for estimating a vehicle speed using the wheel speed or the corrected longitudinal acceleration according to the determination result of the wheel slip determining unit.

Abstract: One embodiment of the present invention provides an electrode sheet processing method comprising the steps of preparing an electrode sheet having an electrode mixture layer disposed on at least one surface of the electrode current collector; removing a part of the electrode mixture layer in the thickness direction by physical processing; and cutting down the region from which the electrode mixture layer of the electrode sheet is removed.

Abstract: A disk receiving and transferring device by which a disk is precisely guided into the disk drive. Disks of different diameter can be inserted into a single disk drive, and at the same time gears are smoothly engaged during power transmission for the clamping of a disk.
