Probe Vehicle Data for Sudden Deceleration Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety driving assistant systems are limited in detecting obstacles at blind spots or far distances, leading to increased installation costs and inability to provide advance warnings for sudden deceleration-prone spots on roads.
Innovation Solution
A safety driving assistant system that acquires probe information from vehicles to detect sudden-deceleration-prone spots based on position and time data, providing this information to target vehicles for proactive safety measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If road-side cameras are installed to detect obstacles at blind spots, then detection capability is improved, but installation cost increases
Solution Approach 1:
The system uses probe vehicles themselves to detect obstacles and generate probe information, eliminating the need for road-side infrastructure. Each vehicle serves as its own sensor node, collecting and transmitting data about sudden deceleration events to identify prone spots without requiring external camera installations.
Solution Approach 2:
Instead of physically installing cameras at every location, the system creates virtual copies of detection capabilities through probe vehicles that report their experiences. The server aggregates this copied data from multiple vehicles to build a comprehensive map of sudden-deceleration-prone spots.
2Measurement precision
If probe information is collected from multiple vehicles to detect sudden-deceleration-prone spots, then detection accuracy is improved, but data processing complexity increases
Solution Approach 1:
The server merges probe information from multiple probe vehicles to collectively identify sudden-deceleration-prone spots. By combining data from many sources, the system achieves high detection accuracy through aggregated evidence while distributing the processing load across the network rather than requiring complex individual vehicle processors.

AI summary
A safety driving assistant system according to one aspect of the present disclosure includes: an acquisition unit configured to acquire pieces of probe information from probe vehicles, each piece of probe information including information of a position of the corresponding probe vehicle and information of a time at which the probe vehicle has passed through the position; a detection unit configured to detect a sudden-deceleration-prone spot where sudden deceleration of probe vehicles frequently occurs, based on the pieces of probe information acquired by the acquisition unit; and a provision unit configured to provide information of the sudden-deceleration-prone spot detected by the detection unit, to a target vehicle that receives safety driving assistance.
