Right-Turn Brake Control for Green Pedestrian Crosswalk Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current advanced driver assistance systems (ADAS) lack the capability to effectively control vehicles when turning right at intersections with crosswalks, especially when pedestrian traffic lights are green, leading to potential accidents and fines for non-compliance.
Innovation Solution
A vehicle system equipped with cameras, detection sensors, and a main controller that identifies pedestrian traffic signals and pedestrian presence, controlling the braking system to stop the vehicle before reaching the crosswalk if a pedestrian is present, ensuring compliance with traffic rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vehicle turns right at an intersection with a crosswalk when the pedestrian traffic light is green, then the vehicle can maintain its speed and improve productivity, but it violates traffic rules and creates safety hazards
Solution Approach 1:
The system performs preliminary detection of pedestrian traffic lights and pedestrians before the vehicle reaches the crosswalk. The controller identifies the green pedestrian signal and pedestrian presence in advance, then proactively controls the vehicle to stop before entering the crosswalk area, ensuring traffic rule compliance while maintaining efficient operation.
2Reliability
If the vehicle stops before the crosswalk to comply with traffic rules, then traffic rule compliance is improved, but the vehicle's operation time increases and productivity decreases
Solution Approach 1:
The system continuously monitors pedestrian traffic light signals and pedestrian detection results, providing real-time feedback to the controller. Based on this feedback, the controller makes dynamic decisions about when to stop and when to proceed, minimizing unnecessary stops and optimizing the balance between compliance and efficiency.
3Productivity
If the vehicle does not stop at the crosswalk, then productivity is maintained, but the risk of pedestrian accidents increases and safety is compromised
Solution Approach 1:
The system takes preliminary anti-action by detecting green pedestrian signals and pedestrians in advance, then preemptively stopping the vehicle before it reaches the crosswalk. This prevents the harmful action of potentially endangering pedestrians while maintaining efficient operation by avoiding unnecessary stops when the crosswalk is clear.
4Object-affected harmful factors
If the vehicle always stops before crosswalks to ensure safety, then pedestrian safety is improved, but the system complexity increases due to additional detection and control requirements
Solution Approach 1:
The system uses a multi-functional controller that integrates pedestrian traffic light recognition, pedestrian detection analysis, and vehicle control functions. This universal controller handles multiple tasks within a single device, improving pedestrian safety while minimizing the increase in overall system complexity through functional integration.
