Abstract
A drift-assessment device includes a turn information detection unit that detects turn information of a vehicle, an image recognition and detection unit that detects position information of the vehicle relative to a lane, a vehicle speed detection unit that detects a vehicle speed, a selection unit that selects the image recognition and detection unit when the vehicle speed is equal to or greater than a predetermined vehicle speed and selects the turn information detection unit when the vehicle speed is less than the predetermined vehicle speed, and a drift-assessment unit that determines the drift of the vehicle based on the position information of the vehicle relative to the lane when the selection unit selects the image recognition and detection unit and determines the drift of the vehicle based on the turn information of the vehicle when the selection unit selects the turn information detection unit.
