Autonomous Vehicle Boundary-Guided Turning for Narrow Area Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in efficiently navigating and covering working areas, particularly in narrow spaces and dead corners, due to poor path planning, which results in reduced coverage efficiency, increased time, and mechanical wear.
Innovation Solution
An autonomous vehicle system with a driving module, limit detecting module, and control module that allows for rational and efficient turning by detecting the location and angle relationship with limits, enabling the vehicle to maintain an acute or right angle with one side of the limit while turning, thereby optimizing path coverage and reducing stopping times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If autonomous vehicles adopt random paths during moving and stop to make turns, then they can navigate obstacles, but they waste time on frequent stop and startup, reducing overall moving speed and working efficiency
Solution Approach 1:
The patent applies dynamics by enabling the autonomous vehicle to perform continuous turning movements without stopping. The vehicle transitions from static stop-and-turn behavior to dynamic continuous motion, where the driving module adjusts wheel speeds to achieve smooth turning while maintaining forward momentum, thereby eliminating frequent stop-and-start cycles and improving working efficiency
Solution Approach 2:
The patent implements preliminary action by having the vehicle detect limits and plan turning paths in advance using the limit detecting module and control module. The control module calculates optimal turning parameters before execution, allowing the vehicle to prepare for continuous turning movements ahead of time, avoiding last-minute stops and enhancing operational efficiency
2Reliability
If autonomous vehicles move straightly in the working scope and brake to stop when encountering obstacles, then they can avoid collisions, but they cannot effectively cover narrow areas and dead corners
Solution Approach 1:
The patent applies curvature by implementing arc-shaped turning paths instead of straight-line motion with sharp stops. The control module generates smooth curved trajectories that allow the vehicle to navigate around obstacles while effectively covering narrow areas and dead corners, transforming rigid straight-line paths into flexible curved paths that enhance coverage scope
Solution Approach 2:
The patent uses dynamics to enable the vehicle to transition from static obstacle avoidance (stop and turn) to dynamic continuous turning motion. The driving module adjusts wheel speeds in real-time during turning, allowing the vehicle to maintain motion while navigating around obstacles, thereby simultaneously achieving collision avoidance and improved coverage of difficult-to-reach areas
3Adaptability or versatility
If autonomous vehicles make frequent stop and startup movements, then they can navigate complex terrains, but they increase mechanical wear and shorten service life
Solution Approach 1:
The patent implements continuity of useful action by enabling the vehicle to perform continuous turning movements without stopping. The driving module maintains motor operation throughout the turning process, eliminating repeated stop-and-start cycles that cause mechanical stress and wear, thereby extending service life while maintaining terrain navigation capability through smooth continuous motion
Solution Approach 2:
The patent applies dynamics by transitioning from static stop-and-turn navigation to dynamic continuous motion. The control module continuously adjusts driving parameters during turning operations, allowing the vehicle to adapt to complex terrains through smooth dynamic movements rather than repeated stopping and starting, reducing mechanical wear and extending service life

AI summary
Disclosed in the present invention is an autonomous vehicle (1), which comprises an housing (21), an driving module mounted on the housing (21), an borderline detecting module mounted on the housing for detecting the distance between the autonomous vehicle (1) and the borderline (3), an energy module mounted on the housing for providing energy for the autonomous vehicle, and an control module electrically connected with the driving module and the borderline detecting module. The control module controls the driving module to perform steering based on the signal representing the angle relationship between the autonomous vehicle (1) and the borderline (3) transmitted from the borderline detecting module, so that the axis (33) of the autonomous vehicle (1) always forms an acute angle or an right angle with one side of the borderline (3) while steering is completed, but another side of the borderline (3) forms an acute angle or an right angle with the core axis (33) of the autonomous vehicle (1) when the turning begins. The turning has directivity, so that the autonomous vehicle more easily goes out from the narrow area and the efficiency of area covering is higher; moving is kept during the turning, so that the energy is saved, and the working efficiency is improved.
