Abstract: A turning control system of a vehicle includes: a database storing road information; a sensor part to detect a steering angle of a vehicle, a wheel speed of the vehicle, whether the vehicle is accelerated, whether the vehicle is braking, and whether a speed gear of the vehicle is shifted; and a controller that determines whether the vehicle enters a turning section based on one or more pieces of the information detected by the sensor part and the road information stored in the database. In particular, when the vehicle is entering the turning section, the controller sets a target speed of the vehicle and controls a speed of the vehicle to be decelerated to the set target speed.

Abstract: A hybrid vehicle and a method of calibrating a traveling direction of the hybrid vehicle are disclosed. The method of calibrating a traveling direction of a hybrid vehicle including a transmission not having a reverse gear includes: when an abnormality of a motor speed sensor is detected, calculating a difference between at least one of a first moving distance calculated based on sensor information during a predetermined time or a second moving distance calculated based on output torque and a third moving distance calculated based on a vehicle speed by a controller for controlling output torque; when an absolute value of the calculated difference is greater than a preset error reference, reversing the traveling direction recognized by the controller; and controlling a powertrain in response to a transmission lever state.

Abstract: Disclosed is a method of controlling a hybrid electric vehicle having a transmission, an engine, and first and second drive motors. The method includes: performing charging through the first drive motor using the power of the engine by engaging an engine clutch disposed between the engine and the first drive motor while a vehicle is stopped with the gear stage shifted to the parking (P) range; turning off the engine and controlling the clutch of the transmission to enter an open state when the gear stage is shifted to the driving (D) range; and commencing movement of the vehicle using the second drive motor alone or using at least one of the first drive motor or the engine together with the second drive motor based on at least one of requested torque, available torque of the second drive motor, or the speed of the first drive motor.
