AI Technical Summary

Technical Problem

Existing driver assistance systems cause panic by activating Autonomous Emergency Braking (AEB) when the path of an oncoming vehicle at an intersection cannot be predicted, leading to unnecessary vehicle stops.

Method used

A driver assistance device that includes a driving environment information acquisition unit, oncoming vehicle information acquisition unit, and a driver assistance control unit, which sets an estimated travel area for an oncoming vehicle based on its behavior and stops the vehicle outside this area if the path cannot be predicted, transitioning to manual driving mode upon driver input.

Benefits of technology

Avoids collisions with oncoming vehicles at intersections without causing panic by predicting vehicle behavior and setting an estimated travel area, allowing safe manual driver take-over when path uncertainty exists.

Abstract

To change a route of an own vehicle to an opposite lane direction by avoiding contact of the own vehicle with an oncoming vehicle even when a route of the oncoming vehicle entering an intersection is unpredictable.SOLUTION: A driving support apparatus 1 includes a driving support control unit 11. When an own vehicle M enters an intersection, the driving support control unit 11 investigates whether or not a route of the oncoming vehicle can be predicted on the basis of the vehicle behavior of the oncoming vehicle. When it is determined that the route of the oncoming vehicle cannot be predicted, the estimated travel area of the oncoming vehicle F is set on the basis of this vehicle behavior, and the own vehicle is stopped in the outside of the estimated travel area.SELECTED DRAWING: Figure 1
