  • Patent number: 11840235
    Abstract: An electric vehicle includes a drive motor configured for generating power required for driving of the vehicle, a twin clutch which may include a first clutch and a second clutch and configured to adjust distribution of the power supplied from the drive motor to a first drive wheel and a second drive wheel of the vehicle through the first clutch corresponding to the first drive wheel and the second clutch corresponding to the second drive wheel, and a controller electrically connected to the twin clutch and configured to, when a control condition for a deceleration turning of the vehicle is satisfied, determine a control torque of the twin clutch as a larger value of an initial torque to prevent slip of the twin clutch and a base torque determined based on output torque of the drive motor, and distribute the control torque to the first clutch and the second clutch depending on a drive mode of the vehicle.

  • Publication number: 20230147926
    Abstract: A method of controlling an electric vehicle including twin clutches includes twin clutches for the electric vehicle driven by power of a drive motor and includes determining, by a clutch controller, whether a releasing condition for releasing engagement of the twin clutches is satisfied, controlling, by the clutch controller, the twin clutches to 0 torque when the releasing condition is satisfied, controlling the drive motor to 0 rpm by a vehicle controller when a torque applied to the twin clutches is less than a predetermined torque, and controlling the drive motor to 0 torque when a speed of the drive motor is less than a predetermined speed.

  • Patent number: 11614132
    Abstract: An apparatus of controlling a twin clutch includes: a twin clutch that selectively blocks power supplied from a drive motor to a pair of drive wheels of a vehicle; and a clutch controller that is configured to control the twin clutch by determining target torques applied to respective clutches included in the twin clutch, based on the straight-line driving state detected by the driving information detection unit, determining a correction error based on a difference between actual torques applied to the respective clutches included in the twin clutch when a preliminary activation signal, which is determined based on the target torques, is turned on and a main activation signal, which is determined based on the actual torques applied to the respective clutches, is turned on, determining a balancing control compensation amount based on the correction error, and determining a final control amounts applied to the respective clutches based on the balancing control compensation amount.
