Roller Speed Feedback for Unmanned Vehicle Inspection Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When vehicles are inspected using unmanned driving, a difference in circumferential speeds between the roller and wheel can cause the wheel to deviate from the roller, potentially leading to contact with other objects.
Innovation Solution
A vehicle inspection system with sensors to detect the likelihood of wheel deviation and a control unit that adjusts the wheel or roller circumferential speeds to minimize the difference between them, preventing wheel deviation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wheel is rotated by a driving force of the roller or the roller is rotated by a driving force of the wheel during vehicle inspection, then the inspection can be performed, but a difference in circumferential speed between the roller and wheel causes the wheel to deviate from the roller
Solution Approach 1:
The system uses sensors to detect the circumferential speed of the wheel and roller, compares them to calculate the speed difference, and feeds this information back to the control unit. The control unit then adjusts the roller's circumferential speed based on this feedback to maintain optimal contact between the wheel and roller, preventing wheel deviation during inspection.
2Reliability
If the circumferential speed of the wheel or roller is controlled to reduce the speed difference, then wheel deviation can be prevented, but the inspection process becomes more complex
Solution Approach 1:
The system automatically adjusts the roller's circumferential speed based on sensor feedback without requiring manual intervention. The control unit autonomously calculates the speed difference and modifies the roller speed accordingly, allowing the system to self-regulate and maintain optimal wheel-roller contact throughout the inspection process.

AI summary
The vehicle inspection system includes: a vehicle that can run by unmanned driving; an inspection facility that includes rollers that rotate while supporting wheels of the vehicle; a sensor that outputs sensor information for detecting that the wheels are likely to deviate from the rollers; a detection unit that detects using the sensor information that the wheels are likely to deviate from the rollers; and a control unit that, when it is detected that the wheels are likely to deviate from the rollers, controls a circumferential speed of at least one of the wheels and the rollers to reduce a difference between a wheel circumferential speed that is the circumferential speed of the wheels and a roller circumferential speed that is the circumferential speed of the rollers.
