摘要： 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.

摘要： A system and method for estimating a wheel speed of a vehicle are provided. The system includes a wheel speed sensor that detects a rotation speed of a wheel of the vehicle and a longitudinal acceleration sensor that detects a longitudinal acceleration of the vehicle. A controller converts the longitudinal acceleration to a wheel acceleration, compensates for the converted wheel acceleration based on a compensation value obtained using wheel speed information, integrates the compensated wheel acceleration, and calculates a wheel speed estimation value based on the integrated wheel acceleration.

摘要： A vehicle is controlled such that a driving mode of the vehicle is automatically selected, where the vehicle can be a Plug-In Hybrid Electric Vehicle (PHEV). The vehicle automatically selects an optimum driving mode from among various driving modes capable of being selected by the PHEV according to a driving situation based on a destination established by a driver who uses a navigation system, or recommends various driving modes to the driver, resulting in increased convenience of use. Through selection of an appropriate driving mode, the vehicle can be driven with superior fuel efficiency, resulting in increased driving efficiency.

摘要： A plug-in vehicle is provided which prevents impossibility of driving even when a charging connector is not connected to the vehicle and a method of controlling the same. The method includes determining whether the vehicle is stopped and determining whether recognition of a connection of the charging connector to the vehicle is enabled. Additionally, the method includes determining whether a charging inlet door is open or closed, in response to determining that recognition of the connection of the charging connector to the vehicle is disenabled, and executing transition of the vehicle from a first state restricting generation of driving power to a second state permitting generation of driving power when the charging inlet door is closed.

摘要： A method and system for controlling a running mode change that prevent shock generated when releasing an engine clutch in changing from a running mode to another running mode. The method includes detecting, by a controller, a running mode change occurring in the hybrid vehicle and determining whether to change a state of the engine clutch from a lock-up state to an open state while the running mode change is being processed. The controller is further configured to slip-control the engine clutch to prevent torque occurring at a point in time when the engine clutch is changed to the open state from being transmitted to a driving shaft connected to the transmission, when the state of the engine clutch is determined to be changed from the lock-up state to the open state.
