Patent number: 10220840Abstract: Disclosed herein are a vehicle configured to prevent a collision and a control method thereof. The vehicle includes a chassis; a steering unit configured to change a direction of the chassis; a brake unit configured to adjust a braking force of the chassis; a detector configured to detect movement information of the chassis; and a controller configured to confirm a variation rate of movement of the chassis based on the detected movement information and configured to automatically control an operation of the steering unit and the brake unit when the confirmed variation rate is out of a reference range. When a collision occurs, the vehicle may automatically perform at least one of steering control, side braking control, or a damping control, and thus a secondary collision may be prevented, the incidence of additional injury may be reduced, the speed of the vehicle may be stably reduced or stopped, and the vehicle may be moved to a safe lane so that a stabilization time of the vehicle may be reduced.Type: GrantFiled: April 19, 2016Date of Patent: March 5, 2019Assignee: Hyundai Motor CompanyInventors: Youn Seok Choi, Jee Yoon Suh
