Solution Overview

Problem

Current accident avoidance systems for vehicles, particularly commercial vehicles, are limited in their ability to reliably and timely evaluate impending driving situations, often resulting in late interventions and incorrect assessments, which reduces their effectiveness in preventing accidents.

Innovation Solution

A method utilizing a neural algorithm trained to categorize current driving situations into non-critical, medium-critical, and critical categories, allowing for proactive interventions based on predicted future scenarios, providing a driver with sufficient time to react and prevent accidents by issuing warnings and enabling preventive measures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional sensor-based accident avoidance systems are used, then accident situations can be detected and responded to, but the assessment is often too late to prevent accidents because the system only reacts after a critical driving situation has already developed

Engineering Contradiction:
Improveaccident prevention effectivenessVSAvoidreaction time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The neural algorithm performs preliminary assessment of driving situations by analyzing current sensor data to predict future critical situations before they actually develop. This allows the system to issue warnings and enable preventive driver interventions 3-4 seconds before an accident would occur, rather than waiting until the situation becomes critical.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The assessment system segments driving situations into three distinct categories (non-critical, medium-critical, and critical) based on neural algorithm evaluation. This segmentation allows for differentiated response strategies and provides drivers with timely warnings at appropriate intervals before accidents occur, optimizing both response time and driver awareness.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If sensor-based systems assess current driving situations, then accidents can be detected, but incorrect assessments occur leading to false predictions that reduce driver acceptance of the system

Engineering Contradiction:
Improveaccident prediction accuracyVSAvoiddriver acceptance
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The system transforms the assessment approach by using a neural algorithm that processes multiple driving situation parameters simultaneously (distances, speeds, accelerations, environmental factors) to generate a comprehensive prediction. This multi-parameter analysis improves prediction accuracy and reduces false positives, thereby maintaining driver acceptance.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system provides feedback to drivers through differentiated warnings corresponding to the three assessment categories. This feedback mechanism allows drivers to understand the system's assessment and take appropriate preventive actions, improving both accuracy and acceptance through continuous driver-system interaction.

Inventive Principle:
Principle #23Feedback

AI summary

The invention relates to a method for predictive assessment of a current driving situation of a vehicle (100), in particular a commercial vehicle (100), comprising at least the following steps: determining currently present driving situation information (FI), wherein the driving situation information (FI) characterises the current driving situation of the vehicle (100), predefining the drive situation information (FI) to a neural algorithm (NA), wherein the neural algorithm (NA) assigns the currently present driving situation information (FI) to a driving situation category (Fki) in the manner of a trained neural network, wherein the respective driving situation category (Fki) is based on a forecast driving situation (GZi), wherein the neural algorithm (NA) determines the forecast driving situation (GZi) on the basis of the current driving situation, and the forecast driving situation (GZi) indicates a driving situation of the vehicle (100) developing in the future from the current driving situation; and outputting an output value (O) characterising the driving situation category (Fki) as an assessment result.
