Vehicle Road Irregularity Passing Using Shared Driving Behavior
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for navigating road irregularities such as speed bumps can lead to accidents, vehicle damage, and discomfort due to improper driving or lack of awareness, particularly when drivers fail to adjust their speed or trajectory appropriately.
Innovation Solution
A method that utilizes detection data from a second vehicle's safe passage of a road irregularity to provide instruction data to a first vehicle, allowing it to mimic the safe driving behavior based on vehicle characteristics and passing behavior analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a vehicle travels at high speed over a road irregularity, then productivity is improved, but safety and comfort deteriorate due to potential accidents and vehicle damage
Solution Approach 1:
The system performs preliminary detection of road irregularities using sensors (cameras, LIDAR, ultrasonic sensors) before the vehicle reaches them. The processing unit calculates optimal passing parameters including reduced speed and trajectory adjustments in advance, allowing the vehicle to maintain high overall productivity while ensuring safety when encountering irregularities.
Solution Approach 2:
The system dynamically adjusts vehicle parameters (speed, trajectory, steering angle) based on real-time detection of road irregularities. The control unit modifies these parameters adaptively - maintaining high speed on normal roads and automatically reducing speed/adjusting trajectory when irregularities are detected, thus resolving the contradiction between productivity and safety.
2Productivity
If a vehicle travels at high speed over a road irregularity, then productivity is improved, but comfort deteriorates due to occupant discomfort
Solution Approach 1:
The system dynamically adjusts vehicle parameters (speed, trajectory, steering angle) based on real-time detection of road irregularities. The control unit modifies these parameters adaptively - maintaining high speed on normal roads and automatically reducing speed/adjusting trajectory when irregularities are detected, thus resolving the contradiction between productivity and safety.
3Adaptability or versatility
If the driver manually monitors and responds to road irregularities, then adaptability is improved, but productivity deteriorates due to distracted driving and delayed reactions
Solution Approach 1:
The system enables the vehicle to detect, analyze, and respond to road irregularities autonomously without driver intervention. Sensors continuously monitor the road ahead, the processing unit automatically calculates optimal passing parameters, and the control unit executes adjustments to speed and trajectory, freeing the driver from distracted monitoring while maintaining high adaptability to various road conditions.
Solution Approach 2:
The system implements continuous feedback loops where sensors detect road irregularities, the processing unit analyzes the data and calculates optimal parameters, and the control unit adjusts vehicle operation accordingly. This automated feedback mechanism provides rapid adaptability to changing road conditions without delaying travel efficiency, as the system responds faster than manual driver reaction times.
