Intersection Braking Assist for Non-Priority Lane Entry Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing braking assist technologies face challenges in preventing collisions between vehicles traveling in non-priority lanes and secondary objects in priority lanes when braking assist is performed to avoid primary objects at intersections.
Innovation Solution
A braking assist control device that acquires environmental information using detectors like millimeter-wave radar and cameras, and performs intersection entry prevention assist by determining if the vehicle is approaching an intersection and traveling in a non-priority lane, thereby preventing the vehicle from entering the intersection and avoiding collisions with secondary objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If braking assist is performed to avoid primary objects at intersections, then collision avoidance with primary objects is improved, but collision risk with secondary objects in priority lanes worsens
Solution Approach 1:
The system performs preliminary detection of intersection environments and identifies both primary objects (requiring braking assist) and secondary objects (in priority lanes) before braking is applied. By提前 recognizing the presence of secondary objects through detectors like millimeter-wave radar and cameras, the system can adjust braking strategies to avoid collisions with both types of objects, thus resolving the contradiction between avoiding primary objects and preventing collisions with secondary objects.
2Productivity
If the vehicle enters the intersection to maintain travel flow, then productivity is improved, but safety deteriorates due to potential collisions with secondary objects
Solution Approach 1:
The system continuously monitors the intersection environment using detectors and provides feedback about the presence of secondary objects in priority lanes. Based on this feedback, the control unit dynamically adjusts the vehicle's travel decisions - allowing entry when safe and preventing entry when secondary objects are detected. This feedback mechanism enables the system to balance productivity (maintaining travel flow) with safety (avoiding collisions with secondary objects).

AI summary
A braking assist control device for a vehicle including a detector and a braking assist control device is provided. The braking assist control device includes an acquisition unit configured to acquire information on an ambient environment of an own vehicle from the detector, and a control unit configured to cause the braking assist device to perform intersection entry prevention assist in a case where it is determined, using the acquired information on the ambient environment, that the own vehicle is approaching an intersection and an own lane in which the own vehicle is traveling is a non-priority lane with respect to an intersecting lane.
