Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing driver assistance systems can be inadvertently deactivated by drivers, leading to potential hazardous situations due to the lack of functional readiness of the emergency stopping function, such as collisions with other road users and obstacles.

Innovation Solution

A driver assistance system with a user interface module, driver monitoring module, and control module that automatically reacts to a predetermined driver status to reactivate the emergency stopping function, ensuring its readiness, particularly in cases of driver fatigue or incapacitation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the emergency stopping function is made deactivatable by the driver, then the ease of operation is improved, but the reliability deteriorates due to potential inadvertent deactivation

Engineering Contradiction:

Improveease of deactivationVSAvoidfunctional readiness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system continuously monitors driver status through the driver monitoring module and provides feedback to the control module. When the driver is deemed incapable of driving, the system automatically reactivates the emergency stopping function, creating a closed-loop feedback mechanism that maintains reliability while allowing driver-initiated deactivation.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs self-monitoring and self-correction by automatically detecting driver incapacity and reactivating the emergency stopping function without external intervention. The driver monitoring module and control module work autonomously to ensure the function remains active when safety requires it.

Inventive Principle:

Principle #25Self-service

2Reliability

If the emergency stopping function is continuously monitored and automatically reactivated, then the reliability is improved, but the device complexity increases

Engineering Contradiction:

Improvefunctional readinessVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The driver monitoring module serves multiple functions: it monitors driver status, determines driver capability, and provides input for emergency stopping function reactivation. This multi-functionality reduces the need for separate dedicated monitoring systems, thereby limiting the increase in device complexity while maintaining high reliability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The control module combines multiple control functions including emergency stop activation, deactivation handling, and automatic reactivation logic in a single integrated unit. This consolidation reduces the number of separate control components needed, balancing reliability improvements with acceptable system complexity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Please substitute the new Abstract submitted herewith for the original Abstract:A driver assistance system (DAS) for a vehicle includes a user interface module that receives a user input to deactivate an emergency stopping function. The DAS includes a driver monitoring module that determines a driver status. The DAS includes a control module that reactivates the deactivated emergency stopping function if the driver status corresponds to a predetermined status.
