Therefore, when the torque demanded by the driver increases sharply (for example, when the degree of accelerator pedal depression is increased by 100%), the engine drive force is unnecessarily increased to the full engine load level, and accordingly, the amount of fuel supplied to the engine is increased, reduced fuel efficiency

The present invention relates to a method for controlling an engine driving force during TCS operation of a hybrid vehicle. The method includes the following steps: calculating a driver-demanded torque based on a detection signal of an accelerator position sensor (APS), determining whether the TCS is operating, and upon determining that the TCS is operating, determining engine driving force basedon a TCS-demanded torque according to the operation of the TCS. Accordingly, the engine driving force (i.e., an engine operating point) is determined based on the TCS-demanded torque requested in order to reduce the torque of the hybrid vehicle during the TCS operation, so as to improve fuel efficiency by reducing fuel consumption during the TCS operation.
Description
[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2016-0105973 filed on Aug. 22, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a method of controlling engine driving force during TCS (Traction Control System) operation of a hybrid vehicle. More particularly, the present invention relates to a method of controlling engine driving force during TCS operation of a hybrid vehicle capable of improving fuel efficiency during TCS operation. Background technique [0004] As known in the art, driving modes of a hybrid vehicle include an EV driving mode in which a motor is driven and an HEV driving mode in which an engine and a motor are driven together. [0005] Such a hybrid vehicle is equipped with a traction control system (TCS) for automatically controlling brakes and motors when the vehicle starts or accelerates on sno...
