Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If autonomous driving features are activated to reduce driver workload, then ease of operation is improved, but driver readiness to take over control deteriorates
Solution Approach 1:
The system performs preliminary actions by periodically testing the driver's readiness before actual autonomous driving scenarios occur. The driving test module initiates simulated scenarios that require driver intervention, preparing the driver in advance for potential takeover situations without compromising the ease of operation during normal autonomous driving.
Solution Approach 2:
The system implements feedback mechanisms by monitoring driver responses during testing and providing information about driver readiness levels. The processor analyzes driver actions and provides feedback that helps maintain appropriate driver engagement while preserving the benefits of autonomous operation, thus resolving the contradiction between ease of operation and driver readiness.
2Reliability
If driving tests are initiated to assess driver readiness, then driver readiness is improved, but loss of time occurs during testing
Solution Approach 1:
The system applies periodic action by conducting driving tests at predetermined intervals rather than continuously. The processor determines when to initiate tests based on time thresholds and driving conditions, allowing the system to assess driver readiness periodically without causing continuous time loss, thus balancing reliability improvement with time efficiency.
Solution Approach 2:
The system uses partial action by implementing brief, targeted testing scenarios rather than extended comprehensive tests. The driving test module activates specific autonomous driving features temporarily to assess critical driver responses, achieving sufficient readiness evaluation with minimal time investment while avoiding excessive testing that would cause significant time loss.
3Measurement precision
If autonomous features are deactivated during testing to assess driver capability, then measurement precision of driver response is improved, but ease of operation deteriorates
Solution Approach 1:
The system implements dynamics by dynamically adjusting the activation state of autonomous driving features based on testing requirements. The processor selectively activates or deactivates specific autonomous driving features during testing scenarios, allowing precise measurement of driver responses when needed while maintaining ease of operation during normal driving conditions, thus resolving the contradiction between measurement precision and ease of operation.

AI summary
Systems and methods are disclosed for guidance, control, and testing of autonomous vehicle features and a driver's response thereto. The system may activate a plurality of autonomous driving features of an autonomous vehicle. In response to a determination to initiate a driving test, the system may generate an indication to a driver of the autonomous vehicle of the initiation of the driving test and may deactivate or adjust parameters of one or more of the plurality of autonomous driving features. The system may receive, from one or more sensors of the autonomous vehicle or one or more sensors of a mobile computing device within the autonomous vehicle, driving data associated with the autonomous vehicle. Based on the driving data associated with the autonomous vehicle, the system may determine the driver's response time and actions taken by the driver during the driving test. Moreover, in response to a determination to end the driving test, the system may reactivate the one or more of the plurality of autonomous driving features previously deactivated or may readjust previously adjusted parameters. In some aspects, based on the driver's response time and actions taken by the driver during the driving test, a drive score may be generated for the driver.
