The invention provides an attention reminding system and an attention reminding method, which can inform a driver of a vehicle of the degree of risk of collision between the vehicle and a preceding vehicle, which changes over time, in a manner close to the subjectivity of a skilled driver. An attention presentation system is provided with: a THW acquisition unit that repeatedly acquires, at predetermined time intervals, an inter-vehicle time, which is a value obtained by dividing the inter-vehicle distance between a host vehicle and a preceding vehicle by the vehicle speed of the host vehicle; a recognition unit that recognizes the type of the preceding vehicle; and a notification unit that, when the vehicle-to-vehicle time is equal to or less than a first threshold value, outputs an approach alarm for notifying the approaching of the preceding vehicle to the occupant of the vehicle, and uses the first threshold value having a value that differs according to the type of the preceding vehicle and/or uses the type of the preceding vehicle to notify the approaching of the preceding vehicle, thereby notifying the approaching of the preceding vehicle to the occupant of the vehicle. A saliency level, which is a degree of saliency of a proximity alarm, is set to a first level having a different size, and the proximity alarm is output.
本发明提供一种注意提醒系统以及注意提醒方法,以接近熟练驾驶员的主观的方式来将随时间变化的本车辆与前行车辆的碰撞风险的大小告知给本车辆的驾驶员。注意提醒系统具备:THW取得部,其以规定的时间间隔反复取得车间时间,该车间时间是本车辆与前行车辆之间的车间距离除以本车辆的车速而得到的值;识别部,其识别前行车辆的种类;以及通知部,在车间时间成为第1阈值以下时,通知部向本车辆的乘员输出用于通知与前行车辆接近的接近警报,通知部使用根据前行车辆的种类而不同的值的第1阈值、以及/或者根据前行车辆的种类,将接近警报的显著性的程度即显著性等级设定为具有不同的大小的第1等级,来输出上述接近警报。
