Trailer Towing Guidance via Leading Vehicle Trajectory Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving support systems for vehicles towing trailers struggle to prevent the vehicle from crossing over the driving allowance region when changing direction, especially due to differences in trailer load, leading to potential collisions with road boundaries.
Innovation Solution
A driving support device and system that uses wireless communication to obtain and synchronize the driving status of a leading vehicle with a towing vehicle, allowing the driver to adjust the towing vehicle's trajectory to match the leading vehicle's path without exceeding the driving allowance region, even with varying trailer loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driving support device uses stored trajectory information from a towing vehicle to guide direction changes, then the driver can follow a predetermined path, but the trailer may still run over the driving allowance region due to differences in trailer load affecting trailer behavior
Solution Approach 1:
The system copies the driving status (position, orientation, trajectory) of a leading vehicle that has successfully navigated the corner without running over the driving allowance region. By replicating the leading vehicle's motion parameters and guiding the following vehicle to match them, the system ensures accurate trajectory following that adapts to actual road conditions and vehicle dynamics, overcoming the limitations of static stored trajectory information
Solution Approach 2:
The system continuously obtains real-time driving status of both the following vehicle and trailer, compares it with the leading vehicle's status, and provides dynamic guidance adjustments. This feedback mechanism allows the system to compensate for variations in trailer load and behavior by continuously adapting the guidance based on actual vehicle performance and position deviations
2Loss of information
If the driving support device provides warning information before direction changes, then the driver is alerted to potential issues, but the driver cannot be supported to restrict running over the driving allowance region during the actual maneuver
Solution Approach 1:
The system performs preliminary actions by obtaining and analyzing the leading vehicle's driving status before the following vehicle initiates its direction change. This allows the system to pre-calculate the optimal trajectory and guidance parameters based on the leading vehicle's proven successful path, enabling the following vehicle to follow a predetermined safe trajectory while still allowing for real-time adjustments
