摘要： An engine clutch control apparatus of a hybrid vehicle is provided. The apparatus includes an engine clutch that is disposed between an engine and a drive motor to selectively connect the engine and the drive motor and an integrated starter-generator that is connected with the engine to start the engine or to generate electricity. A vehicle controller releases or couples the engine clutch to implement a driving mode and determines a chargeable torque and an engine target estimation torque based on a generator rotation speed of the integrated starter-generator. An engine target torque and a charge torque are set based on the chargeable torque and a clutch input torque is generated using at least one of the engine target torque, an engine friction torque, and the charge torque. The engine clutch is then released when the clutch input torque is less than a reference value.

摘要： Provided is a method and a system for controlling engine start of a hybrid vehicle based on acceleration demanded power of a driver. More specifically, a variance of an output signal of an accelerator pedal sensor (APS) senses manipulation of an accelerator pedal reflecting an acceleration demand of a driver. When the variance of the output signal of the accelerator pedal sensor is a positive threshold value, acceleration demanded power corresponding to the output signal of the accelerator pedal sensor is calculated in a section in which the variance is positive and the calculated acceleration demanded power is accumulated. The accumulated acceleration demanded power is then compared with a set power value, and the engine is started to switch from the EV mode to the HEV mode when the accumulated acceleration demanded power is equal to or greater than the set power value.
