Trailer-Aware Blind Spot Display for Tow Vehicle Zone Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blind spot warning systems for tow vehicles with trailers are unclear about which blind spot zone is being used, corresponding to the tow vehicle alone or to the combined tow vehicle and trailer, leading to driver confusion.
Innovation Solution
A system that determines whether a trailer is connected to the tow vehicle and adjusts the blind spot zone accordingly, displaying images on the vehicle's interface to indicate the relevant zone and presence of other vehicles, using sensors and data processing to differentiate between tow vehicle-only and tow vehicle-trailer combined zones.

Engineering Contradiction Analysis
1Area of stationary object
If the blind spot warning system extends the blind spot zone to include the trailer when connected, then the coverage area is improved, but the driver's understanding of which zone is active deteriorates due to confusion between tow vehicle-only and combined zones
Solution Approach 1:
The blind spot zone dynamically changes based on trailer connection status. The system automatically adjusts the monitored area between a smaller zone (tow vehicle only) and a larger zone (combined tow vehicle and trailer) based on whether a trailer is detected as connected, ensuring appropriate coverage without driver confusion
Solution Approach 2:
The system provides visual feedback through display elements that clearly indicate which blind spot zone is currently active. The display shows different visual representations for tow vehicle-only mode versus combined tow vehicle-trailer mode, giving the driver immediate feedback about the current operational state and active monitoring zone
2Loss of information
If the system provides detailed information about trailer connection status and zone configuration, then the driver's understanding is improved, but the complexity of the display system increases
Solution Approach 1:
The display system segments information presentation into distinct visual elements: a first display element shows the blind spot zone boundary, a second display element indicates trailer connection status, and a third display element shows detected vehicles. This segmentation allows comprehensive information delivery while maintaining clarity and avoiding overwhelming the driver with undifferentiated data

AI summary
A blind spot warning method is disclosed for a tow vehicle (102) and includes determining whether a trailer (104) is connected to the tow vehicle (102). Based on the determination whether the trailer (104) is connected to the tow vehicle (102), the determines whether a blind spot zone (302A, 302B) corresponds to the tow vehicle (102) or to the tow vehicle (102) and the trailer (104). At least one instruction is sent to a user interface (120) of the tow vehicle (102) for displaying an image (402) for viewing by a driver of the tow vehicle (102). The displayed image (402) indicates the determination whether the blind spot zone (302A, 302B) corresponds to the tow vehicle (102) or to the tow vehicle (102) and the trailer (104), and indicates a presence or absence of at least one other vehicle (OV) disposed in the blind spot zone (302A, 302B).
