Abstract: A hybrid electric vehicle includes a transmission without a reverse gear and a control method thereof. A situation in which a connection between the motor and the engine is stuck is overcome. When a predetermined condition is met, whether or not an engine clutch is in a specific state is determined. A first driving source is disposed on one end of the engine clutch, and a second driving source is disposed on the other end of the engine clutch. When the engine clutch is in the specific state, reverse driving is prevented. A transmission is controlled to be in a neutral position.

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: An eco-friendly vehicle and a launch control method for an eco-friendly vehicle reduces an unpleasant secondary launch effect based on a gear alignment state of a transmission in a specific situation. The launch control method includes: determining a first condition for enabling a preset stop control when the first condition is satisfied; turning off a control for generating a creep torque of a motor when a brake is released; controlling a transmission in an open state and enabling the control for generating the creep torque; and when a second condition for revolutions per minute (RPM) of the motor is satisfied, controlling the transmission in a lock state through a slip state.
