Solution Overview

Problem

In autonomous driving systems, drivers may become too attentive to their surroundings, leading to decreased awareness of potential hazards, especially during automatic operation, as existing technologies fail to effectively enhance driver attention and response times to emergency situations.

Innovation Solution

An autonomous driving assistance device that predicts hazards and performs additional hazard avoidance procedures based on user-input information, tracking specific monitoring targets and providing supplementary hazard avoidance measures beyond standard automatic operation protocols.

AI summary

A hazard prediction and a hazard avoidance procedure are performed based on a predetermined hazard avoidance condition during an autonomous driving operation of a vehicle. User-input information about a driving operation of the vehicle; is received, and area or object information is checked to determine the area or the object as a monitoring target. The monitoring target is tracked. At least one additional hazard avoidance procedure for the monitoring target is set, and the at least one additional hazard avoidance procedure is performed in addition to the hazard avoidance procedure when the monitoring target approaches the vehicle.
