Vehicle Communication System for Attached Object Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems, such as vehicle-to-vehicle communication, do not accurately account for objects attached to vehicles, like trailers, which can affect the vehicle's collective size, leading to positioning inaccuracies, especially in low visibility conditions.
Innovation Solution
A system comprising a detection device, a controller, and a communication system that detects the presence of an attached object and transmits its information to other vehicles, using sensors, cameras, or proximity sensors to generate signals, prompting the user for details, and then broadcasting this information via wireless communication systems like DSRC or light patterns.

Engineering Contradiction Analysis
1Productivity
If vehicle communication systems transmit basic vehicle position information, then vehicles can be densely packed on roads, but positioning accuracy deteriorates when objects like trailers are attached to vehicles
Solution Approach 1:
The system segments the vehicle-object combination into separate identifiable components by transmitting distinct data packets: one for the vehicle's position and another for the attached object's position and dimensions. This allows receiving vehicles to process each component's spatial information independently, maintaining accurate positioning even when objects like trailers are attached.
Solution Approach 2:
The communication system acts as an intermediary by introducing auxiliary information transmission about attached objects. Instead of directly modifying the vehicle's position data, the system mediates by adding separate object position and dimension data that helps receiving vehicles calculate accurate relative positions, thus preserving positioning accuracy while maintaining road capacity.
2Device complexity
If vehicle communication systems use basic position data, then communication simplicity is maintained, but safety deteriorates in low visibility conditions due to inaccurate positioning
Solution Approach 1:
The system performs preliminary action by proactively transmitting information about attached objects before collisions or safety incidents occur. The vehicle continuously broadcasts object position and dimension data in advance, allowing other vehicles to anticipate and adjust for the extended vehicle configuration, thereby maintaining safety without requiring complex real-time processing during critical moments.
Solution Approach 2:
The system adds another dimension to the communication data by including vertical and lateral dimension information of attached objects, not just horizontal position. This multi-dimensional data provides receiving vehicles with comprehensive spatial awareness of the vehicle-object combination, enhancing safety in low visibility conditions while keeping the communication protocol relatively simple through structured data transmission.

AI summary
An exemplary system for a vehicle having an object attached to it may include a user interface device, a controller, and a communication system. The user interface device may be configured to receive and transmit information relating to the object. The controller may be in communication with the user interface device, and may be configured to receive the information from the user interface device. The communication system may be in communication with the controller, and may be configured to transmit at least a subset of the information to at least one other vehicle.
