Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If electromagnetic induction line is used for autonomous travelling, then vehicle can travel autonomously along the induction line, but large-scale laying construction work is required
Solution Approach 1:
The patent divides the electromagnetic induction line into multiple independent closed-loop sections, each powered by a separate power source. This segmentation allows the system to achieve autonomous travelling without requiring a single large-scale continuous induction line, thereby reducing construction complexity while maintaining automation capability.
2Extent of automation
If electromagnetic induction line is used for autonomous travelling, then vehicle can travel autonomously along the induction line, but large-scale power source is required
Solution Approach 1:
The patent divides the electromagnetic induction line into multiple independent closed-loop sections, each powered by a separate power source. This segmentation allows the system to achieve autonomous travelling without requiring a single large-scale continuous induction line, thereby reducing construction complexity while maintaining automation capability.
3Extent of automation
If vehicle follows electromagnetic induction line, then autonomous travel is achieved, but vehicle cannot deviate from the induction line path
Solution Approach 1:
The patent employs multiple sensors (center, left, right induction line detection sensors) that dynamically detect the vehicle's position relative to the induction line and provide real-time feedback to the control device. This dynamic detection system allows the vehicle to maintain autonomous travel while adapting to path variations and making controlled deviations when necessary.
4Device complexity
If deviation detection reference point is positioned at pivot, then control is simplified, but vehicle cannot maintain proper alignment during turning
Solution Approach 1:
The patent positions the deviation detection reference point forward of the pivot along the vehicle's central line, creating a spatial separation between the detection reference and the turning center. This dimensional offset allows the system to simultaneously simplify control logic while maintaining precise alignment during turning operations by accounting for the geometric relationship between these two points.

AI summary
A steering control system for a vehicle that detects a magnetic field generated from an electromagnetic induction line and that is capable of autonomous travelling along said electromagnetic induction line, where the steering control system includes: a plurality of induction line detection sensors attached to said vehicle: and a control device that, for every control cycle and on the basis of a deviation of said vehicle from said electromagnetic induction line calculated from detection data acquired by said plurality of induction line detection sensors, generates and outputs a travelling control signal that causes said vehicle to turn so as to cancel the deviation or causes said vehicle to advance straight forward, wherein a deviation detection reference point of said plurality of induction line detection sensors is disposed at a position separated from a pivot serving as the turning center of said vehicle.
