AN APPARATUS FOR CONTROLLING ELECTRICAL OIL PUMP OF THE HYBRID TRANSMISSION

摘要

PURPOSE: An electric powered oil pump control device for a hybrid transmission is provided to prevent a high current at an ultra low temperature by operating a transmission through the oil pressure of an oil pump. CONSTITUTION: An electric motor(50) operates an oil pump which generates clutch oil pressure by supplying fluid to a transmission and discharges oil. An electric oil pump controller(90) controls the electric motor by using the battery of a vehicle when a transmission signal of a transmission control unit is generated. A constant voltage supply unit(91) converts the power of the battery into a constant voltage. A main control unit(93) is driven with the power supplied from the outside. A motor driving unit(95) is controlled by the main control unit and drives the electric motor. A motor sensor(97) senses the driving state of the electric motor and supplies the driving state to the main control unit. A communication unit(99) is comprised of a main communication unit and a sub communication unit to communicate the main control unit with the transmission control unit.
