Vehicle Driving Control Using Surrounding ADAS Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle driving systems fail to adaptively control host vehicle operations based on the presence of advanced driver assistance systems (ADAS) in surrounding vehicles, leading to potential safety and efficiency issues during interactions.
Innovation Solution
A vehicle driving control apparatus and method that determines the ADAS status of surrounding vehicles using radar signal interference and image analysis, and adaptively sets ADAS function parameters for the host vehicle to optimize inter-vehicle distances, warning times, and lane changes based on the detected ADAS levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the host vehicle uses fixed ADAS parameters for all surrounding vehicles, then the control system is simple to implement, but safety and efficiency are reduced due to inability to adapt to different ADAS-equipped vehicles
Solution Approach 1:
The patent applies dynamics by making the ADAS parameters adaptive rather than fixed. The control system dynamically adjusts parameters such as inter-vehicle distance, warning time points, and lane change timing based on real-time detection of surrounding vehicles' ADAS status. This allows the system to optimize safety for each specific situation while maintaining a relatively simple overall architecture through parameter-based adaptation rather than complex structural changes.
Solution Approach 2:
The patent implements parameter changes by modifying ADAS function parameters based on the detected ADAS status of surrounding vehicles. Specifically, the system changes parameters including inter-vehicle distance maintenance, warning issuance timing, and lane change execution timing according to whether surrounding vehicles are equipped with ADAS. This approach improves safety through adaptation without requiring fundamental redesign of the control system.
2Reliability
If the host vehicle maintains larger inter-vehicle distance to account for vehicles without ADAS, then safety is improved, but driving efficiency and convenience deteriorate due to excessive spacing
Solution Approach 1:
The patent applies local quality by differentiating the inter-vehicle distance parameter based on the specific characteristics of each surrounding vehicle. Instead of using a uniformly large distance for all vehicles, the system detects whether each surrounding vehicle is equipped with ADAS and adjusts the distance parameter locally for each case. This allows maintaining larger distances only when necessary (when surrounding vehicles lack ADAS) while using smaller, more efficient distances when surrounding vehicles have ADAS, thereby balancing safety and driving efficiency.
3Reliability
If the host vehicle issues warnings earlier for vehicles without ADAS, then safety is improved, but unnecessary warnings increase causing driver annoyance and reduced trust
Solution Approach 1:
The patent applies dynamics by making the warning time point adaptive based on surrounding vehicle detection. The system dynamically adjusts when to issue warnings according to whether the detected surrounding vehicle is equipped with ADAS. Warnings are issued earlier only when necessary (when surrounding vehicles lack ADAS), while normal timing is used when surrounding vehicles have ADAS. This dynamic adjustment maintains safety while avoiding unnecessary warnings that would annoy drivers and reduce trust in the system.
4Reliability
If the host vehicle performs lane changes more conservatively to avoid vehicles without ADAS, then safety is improved, but driving productivity decreases due to delayed lane changes
Solution Approach 1:
The patent implements parameter changes by adjusting the lane change execution timing parameter based on the detected ADAS status of surrounding vehicles. The system changes the lane change parameter conservatively only when surrounding vehicles are detected without ADAS, while allowing normal or more aggressive lane change timing when surrounding vehicles are equipped with ADAS. This selective parameter adjustment improves safety in necessary cases while maintaining driving productivity in situations where it is safe to do so.
