Solution Overview

Problem

Existing driver assistance systems cannot individually adapt warning limits to the driver's preferences or recurring driving situations, leading to unnecessary warnings that reduce user acceptance and safety.

Innovation Solution

The method involves setting warning limits based on driver specifications and location, using sensors and navigation systems to determine distances and adjust limits dynamically, allowing drivers to customize settings for their needs, such as reducing warnings in familiar areas like garages or bottlenecks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed warning limits are used in driver assistance systems, then the system operates simply and consistently, but it causes unnecessary warnings in recurring situations like garages or bottlenecks, reducing user acceptance

Engineering Contradiction:
Improveadaptability to driver preferences and locationsVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system stores warning limits that are specifically adapted to individual drivers and their recurring locations (like garages or bottlenecks) in advance. When a driver enters a vehicle, the system automatically retrieves and applies the pre-configured warning limits associated with that driver and location, eliminating the need for real-time adjustments and reducing unnecessary warnings.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The driver assistance system automatically identifies the current driver and retrieves the appropriate pre-configured warning limits without requiring manual intervention. The system serves itself by automatically adapting to the driver's preferences and location history, eliminating the need for drivers to manually adjust settings each time they use the vehicle.

Inventive Principle:
Principle #25Self-service

2Reliability

If warning limits are set to be conservative (large distances), then novice drivers or older users receive timely warnings for safety, but experienced drivers are annoyed by frequent unnecessary warnings

Engineering Contradiction:
Improvesafety for novice driversVSAvoiduser acceptance by experienced drivers
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system applies different warning limit characteristics tailored to individual drivers' needs and preferences. Each driver can have customized warning limits that reflect their experience level and comfort, allowing novice drivers to receive more conservative warnings while experienced drivers receive more liberal settings, thereby optimizing both safety and user acceptance for different user groups.

Inventive Principle:
Principle #3Local quality

3Reliability

If the system issues warnings frequently to ensure safety, then coverage of potential hazards is improved, but user acceptance decreases due to annoyance

Engineering Contradiction:
Improvesafety coverageVSAvoidannoyance reducing acceptance
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The system pre-configures warning limits based on individual driver preferences and location history before the driver even enters the vehicle. This preliminary customization ensures that warnings are issued at appropriate thresholds for each driver, maintaining safety coverage while avoiding the annoyance of excessive or unnecessary warnings that would reduce user acceptance.

Inventive Principle:
Principle #10Preliminary action

AI summary

A method for assisting a driver of a vehicle having a driving assistance system, comprising the steps of: (a) determining a distance between the vehicle and an object in surrounding area of the vehicle; (b) comparing the distance to at least one warning limit; (c) initiating an action when the object is within the at least one warning limit, wherein the at least one warning limit is adjusted in dependence upon requirements of the respective driver and/or upon the location of the vehicle. The invention also relates to a computer program which performs the method for assisting the driver when said computer program runs on a computer and to a driving assistance system for carrying out the method.
