To provide a lane deviation warning system for issuing a warning at an appropriate vibration level even in an aspect of a transition from a straight path into a curved path.SOLUTION: A lane deviation warning system includes: an image processing section 11 for recognizing a travel lane from an image of a camera 20 for imaging ahead of a vehicle, so as to acquire a relative position of the vehicle on the travel lane; a deviation determination section 12 for determining a possibility of a deviation of the vehicle from the travel lane based on the relative position of the vehicle with respect to the travel lane; excitation means 30 for giving a vibration to a steering wheel of the vehicle as a lane deviation warning when it is determined that there is the possibility of the deviation from the travel lane; a vibration warning control section 14 for controlling the vibration based on a travel state of the vehicle; and a curvature acquisition section 13 for acquiring a curvature of the travel lane from the image. The system is constituted to determine vibration strength according to a vehicle speed and to perform gain-adjustment of the vibration strength based on the curvature of the travel lane.SELECTED DRAWING: Figure 1
【課題】 直線路から曲線路に遷移するような局面でも適切な振動レベルで警報を行える車線逸脱警報システムを提供する。【解決手段】 車両の前方を撮像するカメラ20の画像から走行車線を認識し、走行車線における車両の相対位置を取得する画像処理部11と、走行車線に対する車両の相対位置に基づいて、車両の走行車線からの逸脱可能性を判定する逸脱判定部12と、走行車線からの逸脱可能性ありと判定された場合に、車両のステアリングホイールに車線逸脱警報として振動を与える加振手段30と、車両の走行状態に基づいて前記振動を制御する振動警報制御部14と、前記画像から走行車線の曲率を取得する曲率取得部13を備え、車度に応じて振動強度を決定し、走行車線の曲率に基づいて振動強度をゲイン調整するように構成されている。【選択図】 図1
