Synchronous Radar Modules for Trailer Detection Clutter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic trailer detection systems using short-range radars often fail to accurately determine trailer presence in cluttered environments, leading to intermittent and contradictory indicators for drivers and vehicle systems.
Innovation Solution
Implementing synchronous short-range radar modules on a vehicle that coordinate through a data bus to determine clutter and trailer connection states independently and consistently, preventing contradictory messages by broadcasting clutter and connection messages based on each module's status and the status of the other module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If independent radar modules are used for trailer detection on each side of the vehicle, then the detection coverage is extended, but contradictory and intermittent detection results occur in cluttered environments
Solution Approach 1:
The patent merges the detection results from multiple independent radar modules by having them communicate through a data bus. The radar modules coordinate their detection states (clutter and trailer connection) by exchanging messages, combining their individual observations into a unified determination of trailer presence that resolves contradictions and eliminates intermittent indications.
2Speed
If radar modules operate independently to detect trailers, then detection speed is maintained, but measurement precision decreases in cluttered areas
Solution Approach 1:
The patent implements feedback by having radar modules broadcast their clutter state and trailer connection state to other modules through a data bus. Each module receives feedback from others about the environmental conditions and detection states, allowing them to adjust their interpretations and achieve more accurate trailer detection decisions while maintaining operational speed.
3Reliability
If multiple radar modules are deployed for blind spot detection, then detection capability is improved, but system complexity increases
Solution Approach 1:
The patent applies universality by designing the radar modules with identical functionality and communication protocols. Each module can independently perform clutter detection, trailer detection, and state broadcasting, allowing them to be deployed in multiple locations without increasing coordination complexity. The standardized multi-functional design enables scalable deployment while maintaining system simplicity.

AI summary
Method and apparatus are disclosed for synchronous short range radars for automatic trailer detection. An example radar module for a vehicle includes a radar, and a controller coupled to memory. The controller measures, with the radar, a target area proximate the vehicle. Based on the measurements, the controller determines clutter and trailer connection states. The controller sends a clutter message on a data bus indicative of the clutter state, and sends a connection message based on either (a) the trailer connection state or (b) clutter and trailer connection states of another radar module.
