    摘要： The present invention provides a method for controlling motor torque in a hybrid electric vehicle, which can reduce current control mapping time and simplify control algorithm by providing a torque control compensation logic against a change in temperature of a motor (interior permanent magnet synchronous motor) of the hybrid electric vehicle. The present method includes: forming a single current control map based on an engine room temperature; determining a motor operation range that requires temperature compensation according to motor load conditions such as speed and torque; obtaining an optimization formula for torque command compensation; determining a torque command compensation value using the optimization formula; generating a new torque command with the torque command compensation value and applying the new torque command to the single current control map; and applying to a motor a current for which a torque variation according to a temperature change is compensated.

    摘要： The present invention relates to an Earth Leakage Circuit Breaker (ELCB) used as an electric switch for an electrical circuit which employs a double breakage method of determining whether leakage occurs based on total leakage voltage of a total leakage current detected by a zero-phase current transformer 20 and automatically cutting off the supply of power from a power supply, and determining whether leakage occurs based on the net leakage voltage of a net leakage current synchronously detected by a synchronous detector 90 and automatically cutting off the supply of power from the power supply, so that there are advantages in that the rate of incidence of malfunction of the ELCB is reduced and the leakage breaking function of the ELCB is effectively improved, thereby considerably improving safety.

    摘要： The present invention relates to a method of detecting collisions on a Graphics Processing Unit (GPU). Each collision detection object Oi is projected onto a reference direction, thus obtaining an interval Ii represented by a set {mi, Mi}. Radix sorting based on obtained mi for all Oi, thus obtaining a sorted list L. The sorted list is swept, and then colliding pairs Pi are detected. All colliding pairs are configured into a single set, thus obtaining a final colliding pair P. On a GPU, SaP can be performed on a plurality of collision detection objects in parallel using the blocks of a plurality of threads.

    摘要： Disclosed are an anode active material, a non-aqueous lithium secondary battery, and a preparation method thereof. The surface of a carbonaceous material is modified without using an electrolyte additive, and the reactivity and structural stability of the surface is improved, thereby obtaining long lifetime characteristics without deteriorating charge/discharge efficiency and rate characteristics when applied as an anode active material of a non-aqueous lithium secondary battery. The anode active material comprises a carbonaceous material, and a coating layer formed on the surface of the carbonaceous material through hetero atom substitution, wherein the hetero atom can be phosphorus (P) or sulfur (S). A side reaction with an electrolyte on the surface of the carbonaceous material is inhibited and the structural stability of the surface is enhanced by forming a coating layer on the surface of the carbonaceous material with a hetero atom such as phosphorus (P) or sulfur (S).
