Autonomous Driving Route Adjustment for Heading Angle Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous driving systems lack the ability to flexibly set driving routes, which can lead to abrupt lane changes and reduced passenger comfort, as they do not consider passenger comfort and are limited in adjusting routes based on heading angle changes.
Innovation Solution
A device and method that create a driving route based on a map, detect curved sections by analyzing heading angle changes, and adjust the route by selecting new lane links to reduce heading angle changes, using a processor to calculate and adjust the route to minimize curvature and ensure smoother transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous driving system follows a pre-set route based on precise maps, then the traffic flow and safety are improved, but the ride comfort of passengers deteriorates due to abrupt lane changes and rigid route adherence
Solution Approach 1:
The system dynamically adjusts the driving route by detecting curved sections through heading angle changes and selectively modifying lane links in real-time, transforming the rigid pre-set route into a flexible path that adapts to improve passenger comfort while maintaining safety
Solution Approach 2:
The system changes the route parameters by detecting curved sections based on heading angle thresholds and adjusting the driving path to reduce abrupt lane changes, thereby improving ride comfort without compromising the fundamental safety of autonomous operation
2Stability of the object's composition
If the autonomous driving system adheres strictly to the pre-created route, then the route stability is improved, but the flexibility in adjusting driving paths deteriorates
Solution Approach 1:
The system implements dynamic route adjustment by detecting curved sections through heading angle analysis and selectively modifying lane links, enabling the route to adapt flexibly to improve passenger comfort while maintaining overall stability
Solution Approach 2:
The system segments the driving route into straight sections and curved sections based on heading angle changes, allowing selective modification of only the curved sections while maintaining the stability of straight sections, thus achieving both flexibility and route stability

AI summary
The present disclosure relates to a device and a method for controlling autonomous driving. The device may include a processor, and a memory storing instructions, when executed by the processor, may cause the device to create a driving route based on a map, determine, based on an amount of change in a heading angle of the driving route, a curved section, change the driving route to reduce the amount of change in the heading angle, and control autonomous driving of a vehicle along the changed driving route.
