Track-Mounted Vehicle Path Control With Dynamic Control Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in accurately controlling the movement of track-mounted vehicles along desired paths, particularly in dynamic environments where physical, operational, and environmental characteristics affect movement control.
Innovation Solution
An apparatus comprising a processor and memory configured to obtain path information, characteristic data affecting movement control, determine the position of a control point relative to the vehicle, and control the vehicle's movement to align the control point with the path, thereby ensuring accurate path following.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed control point is used for path following, then the control system is simple, but the vehicle cannot accurately follow paths in dynamic environments with varying characteristics
Solution Approach 1:
The control point position is dynamically adjusted based on vehicle characteristics (width, length, overhangs) and environmental factors rather than being fixed. This allows the control system to adapt to different operating conditions and maintain path following accuracy without requiring an overly complex system architecture
Solution Approach 2:
The system changes the control point parameters (position, offset distances) based on detected characteristics of the vehicle and environment. By adjusting these parameters dynamically, the system achieves high path following accuracy while keeping the overall control structure relatively simple
2Manufacturing precision
If the control point position is dynamically adjusted based on multiple characteristics, then path following accuracy is improved, but the calculation complexity increases
Solution Approach 1:
Different offset distances are applied in different directions (left/right, front/back) based on local vehicle characteristics such as overhangs and track width. This localized approach to control point adjustment achieves high precision without requiring complex global recalculation of the control point position
Solution Approach 2:
The system pre-calculates and stores optimal offset distances for different vehicle configurations and environmental conditions. During operation, it selects from these pre-determined values rather than performing complex real-time calculations, thereby achieving high precision control with reduced computational complexity

AI summary
An apparatus for controlling a track-mounted vehicle includes at least one processor, and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to: obtain information on a path to be followed by the track-mounted vehicle; obtain information on at least one characteristic affecting movement control of the track-mounted vehicle; determine a position of a control point in relation to the track-mounted vehicle based on the at least one characteristic; and control movement of the track-mounted vehicle based on the path and the control point, wherein the control point is configured to be aligned with the path to cause the track-mounted vehicle to follow the path.
