Vehicle Collision Avoidance Lateral Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle collision avoidance assist systems lack effectiveness in preventing secondary accidents when executing avoidance controls, particularly when lateral moving objects like motorcycles or bicycles are present, as they do not adequately consider the risk of collisions with these objects during avoidance maneuvers.
Innovation Solution
The system integrates a lateral object detecting device to prohibit avoidance control execution when a risk of collision with lateral moving objects is detected, ensuring that automatic braking control is prioritized to prevent secondary accidents, and executes avoidance control only when it does not compromise safety with lateral objects, thereby maintaining the vehicle within its driving lane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If avoidance control is executed to avoid forward obstacle, then collision with forward obstacle is prevented, but collision with lateral moving object may occur
Solution Approach 1:
The system applies preliminary anti-action by detecting lateral moving objects before executing avoidance control, and prohibiting the avoidance control when lateral objects are detected. This preventive measure stops the avoidance maneuver before it can cause harm to lateral objects, thus preventing secondary accidents while maintaining the ability to avoid forward obstacles when safe
2Object-affected harmful factors
If avoidance control is prohibited when lateral objects are detected, then secondary accidents are prevented, but ability to avoid forward obstacle is reduced
Solution Approach 1:
The system applies dynamics by making the avoidance control dynamically adjustable based on real-time detection of lateral objects. The avoidance control is prohibited only when lateral objects are detected in the avoidance path, but remains available when no lateral objects are present. This dynamic adjustment optimizes safety by preventing secondary accidents while preserving forward obstacle avoidance capability when conditions permit

AI summary
A vehicle collision avoidance assist system, including: a forward obstacle detecting device; a lateral object detecting device; and a controller including an automatic braking control executing portion to execute an automatic braking control for permitting a brake apparatus to automatically operate, an avoidance control executing portion to execute, in addition to the automatic braking control, an avoidance control for permitting a steering apparatus to automatically operate, and an avoidance control prohibiting portion to prohibit execution of the avoidance control, wherein the avoidance control prohibiting portion prohibits execution of the avoidance control when the lateral object detecting device detects a lateral moving object that is moving on a lateral side of an own vehicle in the same direction as the own vehicle is travelling and there is a risk that the own vehicle and the lateral moving object will collide with each other if the avoidance control is executed.
