Vehicle Collision Control for Trailer-Linked Target Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collision avoidance systems struggle to accurately predict the possibility of collisions between a target vehicle and a subject vehicle when a trailer is connected, as they often treat the target vehicle and trailer as a single entity or independent entities without considering their differing behaviors, leading to inaccurate collision predictions and potentially erroneous vehicle control.
Innovation Solution
A method and apparatus that compares the behavior of a target vehicle with its connected trailer, determining if they are linked or integrated targets, and predicts their future locations to accurately assess collision possibilities, enabling appropriate vehicle operation control, such as avoidance maneuvers or maintaining the current driving route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the target vehicle and trailer are treated as a single entity, then the collision avoidance system simplifies its analysis, but the accuracy of collision prediction deteriorates because the differing behaviors of the vehicle and trailer are not considered
Solution Approach 1:
The system segments the target vehicle and trailer into separate entities for independent behavior analysis. The controller separately determines the behavior of the target vehicle and the trailer, comparing them to identify whether they are linked targets with different behaviors or integrated targets with same behavior. This segmentation allows accurate collision prediction by considering their differing movements while maintaining manageable system complexity.
2Measurement precision
If the target vehicle and trailer are treated as independent entities, then the accuracy of collision prediction improves by considering their differing behaviors, but the complexity of the collision avoidance system increases
Solution Approach 1:
The system merges the analysis of target vehicle and trailer behaviors into a unified linked target determination process. By comparing the behaviors of both entities and determining whether they are linked targets affecting each other, the system integrates their analysis in a coordinated manner. This merging approach maintains accuracy by considering their interdependence while reducing overall system complexity through a structured unified process.
3Ease of operation
If the system does not predict the future location of the trailer based on target vehicle behavior, then the system operation is simpler, but the reliability of collision avoidance deteriorates when the trailer behavior differs from the target vehicle
Solution Approach 1:
The system performs preliminary action by predicting the future location of the trailer based on the current behavior of the target vehicle. The controller determines the current location and behavior of both the target vehicle and trailer, then predicts where the trailer will be in the future. This preliminary prediction enables the system to identify potential collision risks in advance, ensuring reliable collision avoidance while maintaining straightforward operational procedures.

AI summary
A method and apparatus for controlling vehicle. A vehicle control method performed by an apparatus of a host vehicle may include: comparing a behavior of a target vehicle with a behavior of a trailer that is connected to the target vehicle; determining, based on the behavior of the target vehicle being different from the behavior of the trailer, that the target vehicle and the trailer are linked targets that affect each other, determining, based on the linked targets, a possibility of a collision between the host vehicle and the target vehicle to which the trailer is connected; and controlling, based on the possibility of the collision, an operation of the host vehicle.
