A method and system for controlling a hybrid vehicle are provided to supply oil pressure to a transmission using an electric oil pump. The method for controlling a hybrid vehicle including an engine, a driving motor, and an engine clutch connecting between the engine and the driving motor includes: detecting a failure of high voltage components for the hybrid vehicle including an air conditioner, a heater, and a low voltage DC-DC converter (LDC). In response to determining a failure of at least one of the high voltage components an operation of the high voltage components in a normal state are turned off. The electric oil pump is operated with a counter electromotive force generated from the driving motor by operating the driving motor with power of the engine while a speed (RPM) of the engine is maintained at a predetermined minimum demand speed or greater.

A control method of electric vehicle according to an exemplary embodiment of the present invention may include a battery supplying electricity, a motor receiving electricity from the battery and generating power, and a controller controlling the battery and the motor, wherein the controller executes instructions for: detecting a torque command, a motor speed, and a motor current; calculating a motor voltage from the motor current; determining whether voltage utilization according to a speed range of the motor is higher than a predetermined value; generating an operating point correcting function according to the motor speed when the voltage utilization is not higher than the predetermined value; calculating a current command according to the motor speed from the operating point correcting function; and outputting the calculated current command.

Control method and system of electric vehicle

A film capacitor is provided that includes a case in which a film cell is incorporated and a heat radiating plate including a heat absorption unit being positioned adjacent to the film cell while not being in contact with the film cell for absorbing heat and a heat radiating unit being exposed to the outside of the case. Preferred film capacitors can perform a stable operation and have durable lifespan, even when an inverter adopting the film capacitor is mounted on a trunk room and an engine room, by effectively cooling heat generated from a film cell of the film capacitor.
