Problem

Existing systems fail to adequately alert drivers to hazardous road segments and inefficient driving conditions based on individual driving performance, neglecting the unique factors influencing each driver's safety and fuel economy.

Innovation Solution

A method and device that utilize real-time data from a database of driving events to provide personalized advanced warnings to drivers about upcoming road segments with low service levels, considering their past and current driving performance, and road characteristics, to alert them of potential hazards and fuel inefficiencies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If generic hazard warning systems are used to alert all drivers about road hazards, then the coverage and alertness of drivers are improved, but the system cannot account for individual driver performance differences and specific driver needs

Engineering Contradiction:
Improvehazard warning effectivenessVSAvoidpersonalization to driver performance
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system pre-calculates and stores service level values for multiple road segments in advance, based on aggregated driving events from multiple drivers. When a driver approaches a road segment, the system retrieves and compares the pre-calculated service level with the driver's personal performance threshold, enabling personalized warnings without real-time computation delays.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the driver's actual driving performance and compares it against the pre-calculated service levels for upcoming road segments. Based on this feedback, the system dynamically adjusts warnings to match the specific driver's performance characteristics, creating a closed-loop adaptive warning system.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If the system monitors and analyzes individual driver performance in real-time to provide personalized warnings, then the accuracy and relevance of warnings are improved, but the system complexity and data processing requirements increase

Engineering Contradiction:
Improvedriver performance assessment accuracyVSAvoiddata processing system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs complex aggregations of driving events and calculations of service level values in advance, storing results in a database. This preliminary processing eliminates the need for real-time complex calculations, reducing the processing burden during actual driving while maintaining high measurement precision.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system automatically collects, aggregates, and processes driving event data without requiring manual intervention. It self-calculates service level values for each road segment based on aggregated data from multiple drivers, and automatically compares these with individual driver performance thresholds, minimizing operational complexity.

Inventive Principle:
Principle #25Self-service

3Loss of information

If the system provides detailed personalized warnings about specific road segments, then the usefulness and actionability of information to drivers is improved, but the information processing and communication requirements increase

Engineering Contradiction:
Improveinformation relevance to driverVSAvoidinformation processing system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system provides customized information tailored to each driver's specific performance characteristics and the particular road segment ahead. Instead of generic warnings, it delivers localized, relevant information about service levels for specific upcoming segments, ensuring each driver receives precisely the information they need for their driving style and the upcoming road conditions.

Inventive Principle:
Principle #3Local quality

AI summary

A method is described for providing an advanced indication to a driver that a road segment which will require his attention is located along his route. The method comprising: a) detecting the vehicle's current location and identifying a road segment that the driver is about to reach; b) for the identified road segment, retrieving values of driving performance parameters associated therewith; c) evaluating whether any of the retrieved values exceeds a pre-defined threshold, and based on that evaluation, determining whether the identified road segment is a low service level segment and thus would require the driver's attention; and d) providing the driver with an advanced indication indicating the road segment which has been determined as being a segment of a low service level for the driver.
