DEVICE AND METHOD FOR ESTIMATING DYNAMIC INFORMATION

Embodiments of the disclosure relate to a dynamic information estimation technology receiving host vehicle information using one or more sensors, obtaining trailer information using a radar sensor when it is determined that the trailer information is required using the host vehicle information and a yaw rate threshold, determining whether distance information between a host vehicle and a trailer included in the trailer information is included in a preset range and, if it is determined that the distance information is included in the preset range, calculating a trailer hitch angle, mapping the host vehicle information, the trailer information, and the trailer hitch angle and storing as a set, and calculating a trailer yaw rate and a trailer length using the set and an optimization algorithm if a number of sets meets a number condition.
