摘要

A device and a method for realizing an EV(Electric Vehicle) mode of a soft type hybrid vehicle are provided to drive an oil pump in a driving motor, feeding hydraulic pressure for keeping a transmission at 1-speed during the EV mode, thereby obtaining a simpler control logic than a logic using a driving motor and an exterior oil pump. A device for realizing an EV(Electric Vehicle) mode of a soft type hybrid vehicle is composed of a driving motor(6) driven by power of a battery in the EV mode, to generate driving power for initial starting; an engine(1) generating power with synchronizing with the driving motor by an ISG(Integrated Starter Generator,2), to change power in releasing the EV mode; a transmission(3) having the driving motor and an engine clutch(5) installed at a shaft equipped with a torque converter(4) and changing the speed according to the gear level; and a control unit comprising an HCU(Hydraulic Control Unit,11) and a TCU(Transmission Control Unit,10). The HCU receives gear level information through an oil pump(9) combined to a shaft at the front end of the driving motor at a shaft of the transmission connected to the engine, and a shift lever position sensor(12) and pedal operation information through a brake pedal position sensor(13), and judges an EV mode or an HEV(Hybrid Electric Vehicle) mode during an initial starting step. The TCU controls a hydraulic path of a valve body(8) to engage the engine clutch after starting, by supplying hydraulic pressure fed from the oil pump driven by the driving motor, to the transmission.
