Solution Overview

Problem

Inappropriate reporting of agitated driving occurs when a driver of a first vehicle mistakenly perceives normal driving actions by a second vehicle as aggressive due to their own inappropriate driving conditions, leading to unnecessary reports to agencies.

Innovation Solution

An information processing apparatus and method that detects aggressive driving actions by a second vehicle and determines if the first vehicle's driving conditions are appropriate for traffic rules, outputting information only when both conditions are met to prevent false reporting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system notifies the driver of agitated driving when a predetermined action is detected, then the driver can be warned of potential aggressive driving, but inappropriate reporting occurs when the first vehicle's driving condition is actually inappropriate for traffic rules

Engineering Contradiction:
Improveaccuracy of agitated driving detectionVSAvoidinappropriate reporting of agitated driving
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The system performs a preliminary check of the first vehicle's driving condition (whether it is appropriate for traffic rules) before notifying the driver of agitated driving. This preliminary action prevents inappropriate reporting by ensuring that notifications are only issued when the first vehicle is driving appropriately, thus eliminating false positives while maintaining accurate detection of actual aggressive driving incidents.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the system monitors and discriminates driving conditions to prevent false reporting, then inappropriate reporting is suppressed, but the device complexity increases due to additional discrimination processes

Engineering Contradiction:
Improveaccuracy of agitated driving detectionVSAvoidcomplexity of discrimination process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system uses the first vehicle's own driving condition data (acceleration, steering angle, speed) to automatically determine whether the driving condition is appropriate for traffic rules. This self-service approach eliminates the need for external verification systems or complex manual review processes, thereby suppressing inappropriate reporting while keeping the device complexity manageable through autonomous self-assessment.

Inventive Principle:
Principle #25Self-service

AI summary

The purpose is to prevent inappropriate reporting of agitated driving. A controller, comprising at least one processor, of the information processing apparatus detects a predetermined action included in an act of aggressive driving by a second vehicle traveling within a predetermined range from a first vehicle. The controller of the information processing apparatus executes a predetermined discrimination process to determine whether or not the driving conditions of the first vehicle at time when the predetermined action is detected are appropriate for a traffic rules. When the controller determines in the predetermined discrimination process that the driving situation of the first vehicle is appropriate for the traffic rules, the controller outputs the first information to notify the predetermined agency that the second vehicle is driving in an agitated manner toward the first vehicle.
