Abstract: PURPOSE: A driving apparatus of a BLDC(BrushLess Direct Current) motor in a hybrid electric vehicle is provided to reduce a distortion rate of current by detecting a location of a motor in 30° units. CONSTITUTION: A current controller(100) is used for generating signals(AH,AL,BH,BL,CH,CL) for driving a BLDC motor(300) according to a current command signal. A gate drive portion(200) is formed with 6 IGBTs. The IGBTs are connected with an upper drive portion and an upper transistor, respectively. A three-phase coil of the BLDC motor(300) is connected with transistor. A plurality of hall sensor(A,B,C) is used for detecting the magnitude of magnetic field when the BLDC motor(300) is rotated. An inverse electromotive force detection portion(400) is used for detecting inverse electromotive force formed on coils of U, V, and W phases. A location detection portion(500) is used for providing information shifted as much as 30°.

Abstract: PURPOSE: A driving device of hybrid electric motorcar evenly distributes power to four wheels by installing power transmission system of a driving motor on rear wheels to improve the layout inside of an engine room and cooling efficiency and varies driving sources according to the driving condition to improve the efficiency of transmitting power of the engine. CONSTITUTION: A driving device comprises a CVT(Continuous Variable Transmission, 3), an engine(4) and a driving motor(7). When the engine torque is larger than the wheel torque, a first clutch(6) is deactivated and a second clutch(11) is activated to change driving mode into four-wheel drive. When the engine torque is smaller than the wheel torque, the first clutch(6) is activated and the second clutch(11) is deactivated to change driving mode into two-wheel drive.
