车辆用驾驶辅助装置
摘要：
本发明提供车辆用驾驶辅助装置，在行驶路面的一侧的行车线被雪覆盖，只有相反侧的行车线被识别，而且该行车线上设定有行车线偏离判定阈值的情况下，也不频繁地启动偏离警报或者不进行偏离防止控制。控制单元(5)根据立体摄像机(3)拍摄的本车辆(1)前方的图像，虽然可以识别行驶车道的左行车线L1，但右行车线Lr被残雪S覆盖而不能识别的情况下，以残雪S的内侧边缘作为基准设定左行车线偏离判定阈值SL1。其结果，即使因残雪S路面宽度变窄，驾驶员把本车辆(1)偏向行驶在左行车线L1侧的情况下，也不会频繁启动偏离警报或偏离防止控制，可以减轻烦扰。
摘要（英）：

A vehicle drive assist system includes: a lane line recognizing unit that recognizes left and right lane lines defining a lane along which a vehicle equipped with the drive assist system travels; and a drive assist unit that sets lane departure determination thresholds along the left and right lane lines, and performs a drive assist operation based on a relative position of the vehicle to the lane departure determination threshold. The drive assist unit sets a left lane departure determination threshold on the basis of an inner edge of unmelted snow when a left lane line of a traveling lane is recognized based on a front-view image of the vehicle, captured by the lane line recognizing unit, but a right lane line which is covered with the unmelted snow cannot be recognized.
