Abstract: A stop range indication device and a stop range indication method for a vehicle are proposed. The device and the method calculate an estimated stop range of a host vehicle using a variety of pieces of information during deceleration traveling of the host vehicle and provide visual guidance to a driver by displaying a stop range ahead of the host vehicle in accordance to the result of the calculation, thereby enabling the driver to drive safely while recognizing the stop range ahead of the host vehicle.

Abstract: The present disclosure relates to a shift control apparatus of a vehicle and its method. In particular, the shift control apparatus includes: a transmission including a first clutch and a second clutch; a torque source to generate power for driving a vehicle; a data detector to detect a vehicle state data; and a vehicle controller to connect a current stage synchronizer to a next stage driving gear if the vehicle state data satisfy a shift condition, release the first clutch to be connected to the driving gear of a current stage, perform a speed control of a torque source while maintaining the second clutch connected to the driving gear of the next stage in a slip state, and release the second clutch and connect the first clutch if the vehicle stage data satisfy a speed control completion condition to complete a shift to a target stage.

Abstract: A DCT shifting control method of a vehicle includes: a temporary engaging step that engages an N-3 stage gear having a gear ratio larger than an N stage gear that is a currently engaged gear; a first torque switching step that starts to slip a first clutch engaged with the N-3 stage gear and disengages a second clutch engaged with the N stage gear that is the currently engaged gear; a synchronization speed adjusting step that synchronizes a speed of a power source of a vehicle with a desired input shaft speed by controlling the power source of the vehicle, disengages the N stage gear, and engages the N-2 stage gear that is the desired gear, with the slip of the first clutch maintained; and a second torque switching step that finishes shifting by disengaging the first clutch and engaging the second clutch.
