Vehicle Travel Assistance Control for Abnormal Center Line Crossing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Advanced Driver Assist Systems (ADAS) struggle to effectively respond to vehicles abnormally crossing the center line, particularly in situations like intersections, leading to difficulties in providing timely and appropriate vehicle control measures.
Innovation Solution
An apparatus and method utilizing a camera, radar sensor, and Lidar sensor to identify the lane being traveled on and a preceding vehicle's abnormal operation, generating control signals for the vehicle's braking, steering, and display systems to manage center line crossings and other abnormal operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional ADAS excludes vehicles crossing the center line from control objects, then the system operates with simpler control logic, but the system cannot flexibly respond to abnormal vehicle operations
Solution Approach 1:
The system dynamically adjusts its control logic based on the behavior of preceding vehicles. When a vehicle crosses the center line, the system transitions from standard control logic to abnormal operation control logic, enabling flexible response to different driving scenarios while maintaining simplicity in normal conditions
Solution Approach 2:
The system changes the parameter of control object inclusion based on vehicle behavior. Vehicles that cross the center line are dynamically added to the control objects list, transforming the system from a static to a dynamic control framework that adapts to abnormal operations
2Reliability
If the system monitors and responds to center line crossing vehicles, then collision risk is reduced, but the system requires more complex detection and processing capabilities
Solution Approach 1:
The system performs preliminary detection of center line crossing behavior by monitoring vehicle positions and trajectories in advance. By identifying potential abnormal operations before they result in collisions, the system enhances safety while using predictive rather than reactive detection methods
Solution Approach 2:
The system uses the camera and image processing as an intermediary to detect abnormal operations. Rather than directly measuring complex vehicle intentions, the system captures visual data and processes it to identify center line crossing behaviors, simplifying the detection task
3Speed
If the system generates control signals for brake hydraulic pressure, then emergency braking response is improved, but the system requires additional control mechanisms
Solution Approach 1:
The system generates control signals for brake hydraulic pressure in advance when abnormal operations are detected, preparing the braking system for potential emergency stops. This preliminary action reduces response time by pre-positioning the braking system in a ready state
Solution Approach 2:
The control signal generation mechanism serves multiple functions: it controls brake hydraulic pressure for emergency stopping, adjusts vehicle velocity for safe following, and provides warnings to the driver. This multi-functionality reduces the need for separate control mechanisms
