Abstract

The invention discloses a vehicle and a method for controlling the speed thereof. The vehicle may include a dual clutch transmission that adjusts a travel speed of the vehicle based on clutch torque,a brake that makes the vehicle slow down to reduce the travel speed of the vehicle, and a controller that sets a target speed of the vehicle and controls the dual clutch transmission and the brake toallow the travel speed of the vehicle to follow the set target speed. The vehicle may reduce heat generated by a dual clutch, and may cooperatively control a dual clutch transmission and a brake, thereby facilitating efficient speed control during autonomous parking operations.

[0002] This application claims priority from Korean Patent Application No. 10-2017-0173212 filed on December 15, 2017, the entire contents of which are hereby incorporated by reference for all purposes. technical field

[0003] The present invention relates to a vehicle and a method for controlling the speed of a vehicle, and more particularly to a vehicle and a method for controlling the speed of a vehicle during an autonomous parking operation. Background technique

[0004] In vehicles with a fluid torque converter type automatic transmission, engine torque is transmitted through hydraulic fluid. Therefore, first-speed gear engagement is possible even when the vehicle is stopped or traveling at extremely low speeds (0 to 4kph), so that stable engine starting and sufficient torque can be achieved, which enables Effectively control vehicle speed.

[0005] In contrast, in vehicles employing a dual clutch transmission (DCT), the hal...
