WARNING CONTROL APPARATUS

摘要

A warning control apparatus includes a learning section that learns a collision avoidance timing at which a driver of an own vehicle starts to perform an operation for avoiding collision with a front object based on a distance to this object and a speed of the own vehicle, a threshold setting section that determines whether the driver tends to start a collision avoidance operation early or late based on the learned collision avoidance timing, sets an avoidance warning threshold larger than a basic threshold upon determining that the vehicle driver tends to start the collision avoidance operation early, and sets the avoidance warning threshold smaller than the basic threshold in the contrary case, and a warning control section that causes a warning device to issue a warning at a warning timing set so as to become early as the avoidance warning threshold set by the threshold setting section becomes large.

主权项

1. A warning control apparatus comprising:
a distance information acquisition section that acquires front-object distance information showing a front object distance as a distance from an own vehicle to a front object present in front of the own vehicle; a vehicle speed acquisition section that acquires vehicle speed information showing a running speed of the own vehicle; a learning section that learns a collision avoidance timing at which a vehicle driver of the own vehicle starts to perform an operation for avoiding a collision with the front object at least based on the front object distance shown by the front-object distance information and the running speed of the own vehicle shown by the vehicle speed information; a threshold setting section that determines whether the vehicle driver tends to start a collision avoidance operation early or late based on the learned collision avoidance timing, sets an avoidance warning threshold larger than a predetermined basic threshold upon determining that the vehicle driver tends to start the collision avoidance operation early, and sets the avoidance warning threshold smaller than the predetermined basic threshold upon determining that the vehicle driver tends to start the collision avoidance operation late; and a warning control section that causes a warning device to issue a warning for preventing a collision at a warning timing set so as to become earlier as the avoidance warning threshold set by the threshold setting section becomes larger.
