Solution Overview

Problem

Existing vehicle monitoring systems fail to accurately detect events and issue relevant warnings due to incomplete or incorrect data, leading to false alerts that can startle or distract drivers, thereby compromising safety and comfort.

Innovation Solution

A system that integrates modules for capturing driver and external environment data, using GPS for location determination, and processing modules to analyze driving behavior and events, issuing suggestive warnings only when the driver does not take corrective action within a threshold limit, with adjustable alert intensity based on the situation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If monitoring systems issue warnings at high volumes to alert drivers, then driver alertness is improved, but driver distraction and sudden harmful actions increase

Engineering Contradiction:
Improvedriver alertnessVSAvoiddriver distraction
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically adjusts warning parameters including volume intensity, frequency, and type based on driver state and situation criticality. When driver distraction is detected or situation severity is low, the system reduces warning intensity to prevent harmful distractions while maintaining adequate alertness for critical events.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system continuously monitors driver response to warnings and adjusts subsequent warning behavior based on this feedback. If a driver shows signs of distraction or overreaction to warnings, the system modifies future warning parameters to reduce harmful effects while maintaining safety effectiveness.

Inventive Principle:
Principle #23Feedback

2Reliability

If monitoring systems issue frequent warnings to ensure safety, then driver safety is improved, but driver comfort and driving experience deteriorate

Engineering Contradiction:
Improvedriver safetyVSAvoiddriver discomfort
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system applies different warning strategies to different situations and locations. In high-risk areas or during critical events, warnings are issued with higher intensity and frequency. In low-risk situations or areas where warnings are less critical, the system reduces or eliminates warnings to maintain driver comfort and prevent unnecessary discomfort.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system issues warnings selectively rather than continuously. It applies warning actions only when the situation warrants it, using partial action (reduced warning frequency) for minor issues and excessive action (intense warnings) only for critical threats, thereby balancing safety with driver comfort.

Inventive Principle:
Principle #16Partial or excessive action

3Measurement precision

If monitoring systems use multiple data sources to improve detection accuracy, then event detection precision is improved, but system complexity increases

Engineering Contradiction:
Improveevent detection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system divides the complex monitoring task into separate functional modules: driver state monitoring, environment monitoring, event detection, and warning generation. Each module processes specific data types independently, reducing overall system complexity while maintaining high detection accuracy through coordinated operation of specialized subsystems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system employs multi-functional sensors and processing units that can handle multiple data types and detection tasks. For example, cameras serve both driver monitoring and environment monitoring functions, reducing the total number of components needed while maintaining comprehensive detection capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present subject matter relates to providing alerts to the driver based on external environment and location of the vehicle. Data related to external environment to a vehicle is fetched and the location is determined. Based on the fetched external environment data an event is determined. Also, location parameters are also identified. For the location and the parameters of the location, road and the vehicle are determined, the general driving behavior for the particular location is fetched. Based on the determined event warning is generated for a driver of the vehicle. The intensity of the warning is varied based on severity of the event.
