Autonomous Vehicle Bend Path Control Using Occupancy Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing obstacle avoidance methods for autonomous vehicles on curved roads primarily focus on location information of obstacles rather than specific driving conditions, leading to reduced safety due to lack of adaptive control, which can result in failed obstacle avoidance.
Innovation Solution
A bend driving control method for autonomous vehicles that involves obtaining the occupancy width on a target bend and detecting obstacle location information to control the driving route, ensuring the obstacle is outside the occupied area, thereby enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing obstacle avoidance methods focus only on obstacle location information, then the detection system remains simple, but the obstacle avoidance ability deteriorates due to lack of adaptive control
Solution Approach 1:
The patent calculates the occupancy width of the autonomous vehicle on the target bend in advance before obstacle avoidance control is needed. This preliminary calculation of the vehicle's actual occupied space width allows the system to have accurate spatial awareness ready for immediate obstacle avoidance decision-making, improving reliability without adding complex real-time computation
Solution Approach 2:
The patent dynamically adjusts the obstacle avoidance control strategy based on the calculated occupancy width. Instead of using fixed avoidance distances, the system adapts the avoidance behavior to the actual spatial characteristics of the vehicle on bends, enabling context-aware obstacle avoidance that improves reliability while maintaining manageable system complexity
2Reliability
If the autonomous vehicle uses fixed obstacle avoidance distance, then the control logic remains simple, but the safety deteriorates on curved roads due to lack of adaptive control
Solution Approach 1:
The patent changes the key parameter of obstacle avoidance distance from a fixed value to a dynamic value based on occupancy width calculations. By calculating how much space the vehicle actually occupies on a bend and using this to determine avoidance distances, the system adapts to curved road conditions, improving safety while the adaptability is achieved through mathematical calculation rather than complex mechanical or sensor systems
