Vehicle Alert Processing for Preceding Deceleration Warnings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle travel control systems fail to effectively prevent rear-end collisions by not adequately anticipating and responding to rapid deceleration of preceding vehicles, leading to potential safety hazards.
Innovation Solution
An information processing apparatus mounted on a vehicle, equipped with a controller that determines alerts for deceleration in preceding vehicles and performs risk avoidance processes, including notifying the driver and potentially applying automatic braking, based on data transmitted from external devices and other vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system waits for the preceding vehicle to actually decelerate before alerting the following vehicle, then the alert system is simple and reliable, but the following vehicle cannot prepare in time for rapid deceleration, increasing rear-end collision risk
Solution Approach 1:
The system performs preliminary action by detecting alert signals from the preceding vehicle before actual deceleration occurs. When the controller detects an alert signal transmitted by the preceding vehicle, it proactively notifies the following vehicle's driver to prepare for potential rapid deceleration, enabling the following vehicle to take preventive measures in advance rather than waiting for deceleration to actually occur.
Solution Approach 2:
The system applies preliminary anti-action by preparing the following vehicle counter to the potential harmful effect of rapid deceleration. By notifying the following vehicle driver in advance when an alert is detected, the system creates a preparatory state that counteracts the sudden deceleration effect, reducing the risk of rear-end collision before it can occur.
2Reliability
If the system continuously monitors and transmits alert status data between vehicles, then the safety response is improved, but the communication load and system complexity increase
Solution Approach 1:
The system extracts only the critical alert status information from the preceding vehicle and transmits it to following vehicles, rather than continuously transmitting all vehicle data. The controller specifically detects and transmits alert signals and alert status data when relevant, reducing unnecessary communication load while maintaining safety effectiveness.
Solution Approach 2:
The system implements feedback by having following vehicles transmit their alert status data back to other vehicles in the vicinity. When a following vehicle receives an alert notification, it can transmit its own alert status to subsequent vehicles, creating a chain of awareness that propagates safety information through traffic without requiring centralized control.

AI summary
An information processing apparatus mounted on a first vehicle determines that an alert to decelerate is being issued to a driver of a preceding vehicle that precedes the first vehicle; and performs a predetermined process related to risk avoidance when the alert is being issued is the preceding vehicle.
