  • Publication number: 20210370923
    Abstract: A hybrid electric vehicle and a method of controlling the same are provided to avoid a collision thereof attributable to erroneous operation of an accelerator pedal. The method includes determining whether an accelerator pedal is erroneously operated in the situation in which an obstacle is detected to be present in the traveling path. In response to determining that the accelerator pedal is erroneously operated, the method includes switching the driving mode to a mode in which an engine is disconnected from a driving shaft and a motor generates driving force. The number of revolutions per minute (RPM) of the engine is then adjusted based on the extent to which the accelerator pedal is operated and the torque of the motor is adjusted based on a first vehicle speed and the distance to the obstacle.

  • Patent number: 11085530
    Abstract: An active shift control method for a power-off downshift of the hybrid vehicle is provided. The method includes increasing the torque of an engagement clutch in a transmission while disengaging a disengagement clutch by reducing the torque of the disengagement clutch in the transmission, when the shift of a power-off downshift is requested. A motor speed is adjust for a transmission input shaft rotary speed to reach a predetermined target stage synchronization speed of a target stage after shifting, and the torque of the engagement clutch is maintained in a state where the disengagement clutch has been disengaged. The engagement of the engagement clutch is completed by increasing the torque of the engagement clutch when the transmission input shaft rotary speed has reached the target stage synchronization speed.
