Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles lack efficient systems to determine the authenticity of speed bumps, particularly those with irregularities, which can cause confusion and potential accidents.
Innovation Solution
A vehicular electronic device equipped with a camera unit, sensor unit, and processor to capture and analyze images for speed bumps, detect irregularities, and transmit relevant information to a service server, generating alarms only when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle is equipped with a speed bump detection system using camera and image processing, then the ability to identify speed bumps is improved, but the system cannot distinguish between authentic speed bumps with irregularities and fake speed bumps without irregularities
Solution Approach 1:
The system performs preliminary detection of speed bumps using image capture and processing before the vehicle reaches them. The processor analyzes the captured images to identify speed bump locations and characteristics in advance, allowing the system to prepare appropriate warnings or alerts before the vehicle encounters the actual speed bump.
Solution Approach 2:
The system detects irregularities on speed bumps by analyzing color variations and patterns in the captured images. Authentic speed bumps with irregularities exhibit specific color distributions and patterns that differ from fake speed bumps, allowing the processor to distinguish between them based on visual characteristics.
2Reliability
If the system generates alarms for all detected speed bumps, then driver awareness is improved, but driver confusion increases due to false alarms from fake speed bumps
Solution Approach 1:
The system provides feedback to the driver only when authentic speed bumps with irregularities are detected. The processor analyzes the detected speed bump characteristics and generates warnings or alerts based on the authenticity determination, ensuring that drivers receive information that is both accurate and actionable.
3Measurement precision
If the system processes and analyzes images in real-time to determine speed bump authenticity, then detection accuracy is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs partial image processing by focusing on key characteristics such as color distribution, pattern recognition, and irregularity detection rather than analyzing every pixel in detail. This approach maintains sufficient accuracy for authenticity determination while reducing computational complexity and processing time.

AI summary
According to an embodiment of the present invention, a method for controlling a vehicular electronic device comprises capturing an image in front of a vehicle, detecting a speed bump from the captured front image, obtaining information on the vehicle's location when the speed bump is detected, generating location information of the speed bump based on the obtained location information of the vehicle, determining whether the speed bump includes irregularities and generating speed bump information using at least one of information on whether the speed bump includes irregularities and information on a location of the speed bump, and transmitting the speed bump information to a vehicle service providing server. According to the present invention, an alarm is generated only when a speed bump ahead of the vehicle includes irregularities, thereby reducing user confusion.
