Driving Control System Elegance Evaluation Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driving control systems lack a statistical method for evaluating performance, identifying areas of improvement, and adjusting driving characteristics to achieve a comfortable and elegant, human-like driving experience.
Innovation Solution
A method is developed to measure the elegance of a driving control system by comparing its driving metrics to those of manually controlled vehicles, using a pre-determined distribution of data to statistically evaluate performance and adjust the system based on identified areas of improvement, with a scoring system that calculates an elegance score for different versions of the driving control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If driving control systems use higher speeds for turns, then driving elegance is improved, but passenger comfort may deteriorate
Solution Approach 1:
The system dynamically adjusts driving parameters (speed, acceleration, steering angle) based on road geometry and context. For turns, it calculates optimal speed profiles that balance elegance (higher speeds) with comfort (smooth transitions), using continuous parameter modification rather than fixed rules
Solution Approach 2:
The driving control system transitions from static speed limits to dynamic speed profiling, where velocity, acceleration, and jerk are continuously adjusted throughout the maneuver. This allows the vehicle to accelerate into turns and decelerate out of them smoothly, maintaining both elegance and comfort
2Adaptability or versatility
If driving control systems are updated with new versions, then driving characteristics improve, but evaluation and testing complexity increases
Solution Approach 1:
The patent replaces manual, subjective evaluation of driving characteristics with automated statistical analysis. Sensors and processors continuously collect driving data and compare it against benchmarks, eliminating the need for complex manual testing procedures
Solution Approach 2:
The system implements continuous feedback loops where driving performance is measured, compared to target characteristics, and used to automatically adjust control parameters. This automated feedback mechanism simplifies evaluation by providing quantitative metrics rather than requiring complex qualitative assessment
3Object-affected harmful factors
If driving control systems prioritize comfort over elegance, then passenger comfort is improved, but driving elegance deteriorates
Solution Approach 1:
The system uses multiple adjustable parameters (velocity, acceleration, jerk, steering rate) that can be independently tuned. By modifying these parameters in combination rather than singly, the system achieves both comfort (smooth transitions) and elegance (appropriate speeds and timing")
Solution Approach 2:
The system applies partial acceleration and deceleration profiles that are neither fully aggressive nor fully conservative. By using intermediate acceleration rates and extended maneuver durations, it achieves a balance between comfort and elegance that neither extreme alone could provide

AI summary
In particular embodiments, a computing system may determine a measured driving characteristic of a driving control system based on observations of vehicles driven by the driving control system. The system may determine a difference between the measured driving characteristic and a target driving characteristic, which is based on objectivations of one or more manually controlled vehicles. The system may determine an evaluation objective for the driving control system. The system may determine a weight function for the evaluation objective. The system may determine a score for the driving control system with respect to the evaluation objective by weighting the difference between the measured driving characteristic and the target driving characteristic using the weight function. The system may apply, based on the score, an adjustment to the driving control system to reduce a difference between a subsequently measured driving characteristic of the driving control system and the target driving characteristic.
