Hybrid electric vehicle and method for ignition control for same

Abstract

The present disclosure relates to a hybrid electric vehicle and a method for ignition control for the same. The hybrid electric vehicle includes a power train including an engine, a motor, and a shaft to which the engine and the motor are connected together. The vehicle also includes a controller configured to predict, during the ignition, a torque change in the shaft by determining whether to apply a vibrational contribution due to combustion pressure torque according to whether initial explosion has occurred during ignition of the engine, and control torque of the motor during the ignition based on the predicted torque change, which can reduce vibration in an ignition process of the hybrid electric vehicle and enhance startability by predicting vibration and applying antiphase torque during ignition.

Dependencies are inferred from the claim text.
