摘要： 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.

摘要： 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.

摘要： A method of controlling traveling of a vehicle may include a measuring step that measures a longitudinal acceleration sensing value by a longitudinal acceleration sensor on a vehicle, a longitudinal acceleration calculating step that calculates a longitudinal acceleration of the vehicle from a speed of the vehicle, a slope degree calculating step that calculates a slope degree of a ground on which the vehicle is, from the longitudinal acceleration sensing value and the calculated longitudinal acceleration, a determining step that determines a slope direction and a slope level of the ground from the calculated slope degree, and a controlling step that provides in advance a torque amount, which is distributed from main driving wheels to sub-driving wheels for traveling, to a power distribution device, at different levels in accordance with the slope direction and the slope level of the ground.
