Abstract: A method for controlling driving of a vehicle includes diagnosing whether or not a wheel speed sensor has failed when a shift lever is changed to an R-range while a vehicle travels in a lowest forward gear provided on a same shaft as a reverse gear is provided, disengaging the lowest forward gear and then engaging the reverse gear when the wheel speed sensor is diagnosed to be in a normal state, and calculating a vehicle speed using the wheel speed sensor in a simultaneous disengagement range, in which an odd gear and an even gear are simultaneously disengaged, during gear engagement in the disengagement of the lowest forward gear and then engaging the reverse gear.

Abstract: A control method of a hybrid vehicle includes: confirming whether or not the driving mode of the vehicle is an EV mode when a controller senses shift of the position of a shift lever from the position R to the position D or from the position D to the position R; applying reverse-directional motor torque to a motor through the controller so that a motor speed is synchronized with the speed of an engagement-side clutch, as a result of confirmation of the driving mode, if the driving mode of the vehicle is the EV mode; and executing normal driving of the vehicle by applying regular-directional motor torque to the motor through the controller after synchronization of the motor speed with the engagement-side clutch speed.

Abstract: Disclosed herein is a technique for improving drivability of a vehicle by controlling the driving of the vehicle by a double clutch when the clutch of a double clutch transmission (DCT) is overheated. There is provided a shift control method for a hybrid vehicle with a DCT. In particular, where it is desired to perform shifting when one of clutches of the DCT is overheated, double-clutch shifting is performed using a non-overheated clutch and an engine clutch without using the overheated clutch, thereby reducing disharmonic shifting in virtue of a small difference in gear ratio during shifting and improving shifting and driving performance.
