  • SYSTEM AND METHOD OF CONTROLLING ENGINE CLUTCH ENGAGEMENT DURING TCS OPERATION OF HYBRID VEHICLE
    Publication number: 20180056980
    Abstract: A system and method of controlling engine clutch engagement during TCS operation of a hybrid vehicle are provided. The method includes determining whether a TCS is operating and upon determining that the TCS is operating, determining a compensation value for early engagement of an engine clutch during the TCS operation based on a difference between a front wheel speed and a rear wheel speed and a slip amount of front wheels. Additionally, the method includes determining whether engagement of the engine clutch is capable of being started based on the compensation value and starting the engine clutch engagement. Since the engagement of the engine clutch is controlled based on the speed of non-drive wheels during TCS operation, the engagement stability of the engine clutch is improved and the amount of time required to engage the engine clutch is decreased.

  • METHOD OF CONTROLLING ENGINE DRIVING FORCE DURING OPERATION OF TRACTION CONTROL SYSTEM OF HYBRID VEHICLE
    Publication number: 20180050683
    Abstract: A method of controlling an engine driving force during operation of a traction control system (TCS) of a hybrid vehicle includes: 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 based on a TCS-demanded torque according to 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.
