Drive control apparatus

摘要

This drive control apparatus, includes: a traveling speed detection portion that detects a traveling speed of an own vehicle; an object detection portion that detects an object around an own vehicle and obtains an object detection result; a time-to-collision calculation portion that calculates time to when the object and the own vehicle collide against each other based on the traveling speed and the object detection result; and an alarm portion that raises an alarm to a driver based on the time to collision, in which the alarm portion: obtains reference alarm start time that is preset as a reference value for starting the alarm, and a predetermined distance that is preset as a minimum value of an error in distance perception of the driver; adds time obtained by dividing the predetermined distance by the traveling speed and raises the alarm to the driver.

1. A drive control apparatus, comprising:
a traveling speed detection portion that detects a traveling speed of an own vehicle; an object detection portion that detects an object around an own vehicle and obtains an object detection result; a time-to-collision calculation portion that calculates time to when the object and the own vehicle collide against each other based on the traveling speed and the object detection result; and an alarm portion that starts an alarm based on the time to collision, wherein the alarm portion:
obtains reference alarm start time that is preset as a reference value for starting the alarm;obtains a preset predetermined distance which is a minimum value of an error in distance perception of a driver;adds time obtained by dividing the preset predetermined distance by the traveling speed to the reference alarm start time to find an alarm activation start threshold time; andthe alarm is started based on the alarm activation start threshold time and on the time to collision, wherein the alarm activation start threshold time is increased so that the alarm is started at an earlier time, and wherein the preset predetermined distance is a difference between an approach limit distance where time to collision is the reference alarm start time and a distance at which the driver perceives that the driver cannot approach any further.
