Adjustable Track Bump-Dip Control for Vehicle Position Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bumps and dips in vehicle factory tracks can degrade the accuracy of vehicle control during automatic driving by causing speed and position inaccuracies.
Innovation Solution
A system with bump/dip portions that can adjust their height difference to accommodate both manned and automatic driving modes, using a bump/dip controller to manage the height difference based on vehicle type and manufacturing step information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bumps are provided on the track to allow visual confirmation of vehicle entry/exit zones during manned driving, then ease of operation is improved, but manufacturing precision deteriorates due to speed and position inaccuracies during automatic driving
Solution Approach 1:
The bump/dip portion is designed to be movable rather than fixed, allowing its height relative to the track to be dynamically adjusted. The bump/dip controller changes the height difference between the bump/dip portion and the track based on whether the vehicle is in manned or automatic driving mode, thus adapting the track characteristics to different operational requirements
Solution Approach 2:
The physical parameter of the bump/dip portion (its height difference relative to the track) is changed based on the driving mode. During automatic driving, the height difference is reduced or eliminated to maintain control accuracy, while during manned driving, the height difference is maintained or increased to provide visual feedback for zone entry/exit confirmation
2Ease of operation
If the bump height is increased to improve visual confirmation during manned driving, then ease of operation is improved, but vehicle control accuracy deteriorates during automatic driving
Solution Approach 1:
The bump/dip portion's height is made dynamically adjustable through the bump/dip controller, which modifies the height difference relative to the track based on real-time driving mode detection. This allows the system to optimize the bump height for visual confirmation during manned driving while minimizing its impact on measurement precision during automatic driving
Solution Approach 2:
The bump/dip portion serves multiple functions depending on the driving mode: it provides visual confirmation feedback during manned driving and becomes a minimized or eliminated obstacle during automatic driving. This multi-functionality allows a single structure to address both operational ease and measurement precision requirements

AI summary
A system comprises: a bump/dip portion that is at least one of a bump configured to project freely from a track on which a vehicle is to run and a dip configured to be depressed freely from the track, the bump/dip portion being configured to allow the vehicle to get thereover, and a bump/dip controller that controls a height difference between the bump/dip portion and the track by operating the bump/dip portion.
