  "textContent": "An engine clutch disengagement control method for a hybrid electric vehicle is disclosed to overcome a sense of discontinuous travel caused when an engine clutch is disengaged due to influence of the inaccuracy of model engine torque. The method includes: acquiring vehicle acceleration information during engine clutch disengagement control of the hybrid electric vehicle, determining whether a predetermined condition for determining inaccuracy of model engine torque required for engine clutch disengagement control is satisfied from the acquired vehicle acceleration information, when the predetermined condition is satisfied, determining a situation in which the model engine torque is inaccurate and calculating target compensation torque using the vehicle acceleration information, calculating a target slippage amount in a transmission clutch using the calculated target compensation torque, and performing transmission clutch torque control for inducing slippage in a transmission clutch based on the target slippage amount and a current transmission speed.",
