Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an autonomous driving kit is made attachable and detachable to enable flexible use, then ease of operation is improved, but reliability deteriorates because autonomous driving cannot continue if an abnormality occurs in the kit functions
Solution Approach 1:
The patent introduces an active safety device as an intermediary component between the autonomous driving kit and the vehicle control system. This active safety device independently monitors the driving environment and can intervene in vehicle control when abnormalities are detected in the autonomous driving kit, thereby maintaining reliability while preserving the flexibility of the attachable/detachable kit design
Solution Approach 2:
The patent implements beforehand cushioning by equipping the vehicle with an active safety device that proactively monitors the autonomous driving kit's status and prepares backup control capabilities. When abnormalities are detected, the active safety device can immediately intervene to prevent failures, cushioning the impact of potential kit failures before they compromise driving continuity
2Device complexity
If the autonomous driving kit is given full control authority to simplify the control system, then device complexity is reduced, but safety deteriorates because there is no independent verification of driving performance
Solution Approach 1:
The patent implements feedback by introducing an active safety device that continuously monitors the autonomous driving kit's performance and the driving environment. The active safety device receives information from both the autonomous driving kit and independent sensors, compares the autonomous driving decisions with its own assessment, and can intervene when discrepancies or abnormalities are detected, providing independent verification without significantly increasing system complexity

AI summary
A vehicle includes an interface unit that is configured to be able to communicate with an autonomous driving kit configured to be attachable to and detachable from the vehicle and that gives a control instruction related to autonomous driving control to each part of the vehicle based on an instruction from the autonomous driving kit, and an active safety device that implements an active safety function of the vehicle. The active safety device includes an acquisition unit that acquires at least one piece of participant information that is information related to a traffic participant present around the vehicle, and occupant information that is information related to an occupant riding in the vehicle; and a performance evaluation unit that evaluates driving performance of the autonomous driving kit based on at least one piece of the participant information and the occupant information.
