Abstract:
1. A method of controlling start of an engine in a hybrid vehicle running in an electric vehicle (EV) mode using only power from an electric motor or in a hybrid electric vehicle (HEV) mode using power from both the electric motor and power of the engine together, the method comprising: calculating, by a controller, variance of an output signal of an accelerator pedal sensor (APS) configured to sense manipulation of an accelerator pedal reflecting an acceleration demand of a driver; in response to the calculated variance of the output signal of the accelerator pedal sensor being a positive threshold value: wherein the set power value is set to be less than a power value corresponding to a discharge allowance maximum value of a battery configured to supply power to the electric motor, and the acceleration demanded power is calculated through torque and a speed of the vehicle according to mapping of the accelerator pedal sensor.
