Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The diversity and complexity of autonomous driving algorithms make it difficult to compare and determine the safety and efficacy of different algorithms, especially in varying conditions, leading to challenges in ascertaining when one algorithm is safer than another or when a combination of algorithms is more unsafe.
Innovation Solution
A computing device analyzes telematics data from vehicles to determine performance metrics of autonomous driving algorithms, comparing them to other algorithms, assigning an autonomous vehicle score, and sending indications to replace algorithms if they fail to meet safety thresholds or deviate from marketed performance capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If autonomous driving algorithms are made more complex to handle all aspects of driving, then the degree of autonomous driving capability is improved, but the safety and reliability may deteriorate due to increased complexity and difficulty in comparison
Solution Approach 1:
The system implements continuous monitoring and evaluation of autonomous driving algorithm performance through telematics data collection. Performance metrics are calculated and compared against thresholds, with feedback loops that enable identification of unsafe conditions and triggering of alerts or interventions. This closed-loop feedback mechanism ensures that complex algorithms remain reliable through ongoing assessment and correction.
Solution Approach 2:
The patent introduces an intermediary evaluation system that acts as a mediator between the autonomous driving algorithms and safety assessment. This intermediary layer collects telematics data, processes performance metrics, and provides objective comparisons without directly controlling the driving algorithms themselves, thus maintaining safety oversight while allowing algorithmic complexity to flourish.
2Reliability
If multiple autonomous driving algorithms are executed to improve safety through comparison, then the safety may be improved, but the device complexity and difficulty of comparison increase prohibitively
Solution Approach 1:
The system transforms the complex problem of algorithm comparison into a standardized parameter-based evaluation framework. By defining specific performance metrics and thresholds, the system converts qualitative safety assessments into quantitative parameter comparisons, making it feasible to evaluate multiple algorithms systematically without prohibitive complexity.
Solution Approach 2:
The evaluation system segments the complex task of algorithm comparison into distinct performance metrics and evaluation categories. By dividing the overall safety assessment into measurable components, the system enables manageable comparison of multiple algorithms through structured metric analysis rather than holistic complex evaluation.
3Measurement precision
If telematics data is continuously collected and analyzed to evaluate algorithm performance, then the measurement precision of safety metrics is improved, but the use of energy and computational resources increases
Solution Approach 1:
The system applies partial action by selectively collecting and analyzing only the most relevant telematics data points necessary for performance metric calculation. Rather than processing all available data continuously, the system focuses on critical parameters that directly impact safety assessment, reducing computational energy consumption while maintaining measurement precision.

AI summary
Methods and systems for autonomous driving algorithm evaluation are described herein. A computing device may receive, via telematics sensors associated with a vehicle, telematics data corresponding to one or more trips taken by the vehicle during a period of time. Portions of the telematics data corresponding to use of an autonomous driving algorithm may be determined. One or more performance metrics of the autonomous driving algorithm may be determined based on the portions of the telematics data corresponding to use of the autonomous driving algorithm. The one or more performance metrics may be compared to one or more other performance metrics, such as those corresponding to other autonomous driving algorithms. An autonomous vehicle score may be assigned to the autonomous driving algorithm. Based on the autonomous vehicle score, an indication of a second autonomous driving algorithm may be sent to the vehicle.
