Roller Speed Feedback to Prevent Wheel Deviation in Vehicle Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When vehicles are inspected using unmanned driving, a difference in circumferential speed 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 that includes sensors to detect the likelihood of wheel deviation, with a control unit adjusting either the wheel or roller circumferential speed to minimize the speed difference and prevent deviation.

Engineering Contradiction Analysis
1Productivity
If the vehicle runs by unmanned driving on the inspection facility, then the inspection efficiency is improved, but the wheel may deviate from the roller due to speed difference
Solution Approach 1:
The system uses sensors to detect the position and speed of the wheel on the roller, and feeds this information back to the control unit. The control unit adjusts the roller speed based on the detected wheel speed to maintain proper contact, preventing wheel deviation while preserving unmanned driving inspection efficiency.
Solution Approach 2:
The system dynamically changes the operational parameters (circumferential speed) of the roller based on real-time detection of wheel speed and position. By adjusting the roller speed parameter to match the wheel speed, the system prevents deviation while maintaining efficient unmanned inspection operations.
2Reliability
If the roller circumferential speed is adjusted to match wheel speed, then wheel deviation is prevented, but the control system complexity increases
Solution Approach 1:
The system allows the wheel's own rotation to determine the required roller speed. The sensor detects the wheel speed, and the control unit automatically adjusts the roller speed to match, making the system self-regulating without requiring complex external control mechanisms.
Solution Approach 2:
The system replaces complex mechanical speed synchronization mechanisms with a sensor-based detection and electronic control approach. This substitution reduces mechanical complexity while achieving reliable wheel-roller speed matching to prevent deviation.

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.
