Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the autonomous vehicle travels in the first autonomous traveling mode without driver operation, then productivity is improved, but safety deteriorates in situations with blind spots or complex traffic conditions
Solution Approach 1:
The system dynamically switches between the first autonomous traveling mode and the second autonomous traveling mode with driver operation based on detected traveling conditions and circumferential conditions. The controller transitions from fully autonomous operation to driver-assisted operation when safety concerns are detected, resolving the contradiction between productivity and safety by making the operating mode adaptive rather than fixed
Solution Approach 2:
The condition detector continuously monitors traveling conditions and circumferential conditions, providing feedback to the controller. Based on this feedback, the controller determines whether to maintain the first autonomous traveling mode or switch to the second autonomous traveling mode with driver operation, ensuring safety while preserving productivity when conditions permit
2Reliability
If the autonomous vehicle switches between traveling modes based on driver operation, then safety is improved, but device complexity increases
Solution Approach 1:
The controller performs multiple functions: it manages the first autonomous traveling mode, monitors conditions via the condition detector, determines operating sections, and switches to the second autonomous traveling mode when needed. By making the controller multi-functional rather than requiring separate dedicated systems for each function, the patent improves safety while minimizing the increase in device complexity
Solution Approach 2:
The condition detection function, mode determination logic, and vehicle control functions are merged into an integrated system. The condition detector and controller work as a unified control architecture that automatically manages mode transitions, reducing the need for separate complex subsystems while maintaining high safety standards

AI summary
An autonomous vehicle operating apparatus is installed in an autonomous vehicle having two autonomous traveling modes of a first autonomous traveling mode for traveling without operation by a driver and a second autonomous traveling mode for traveling in accordance with an operation by the driver. The autonomous vehicle operating apparatus defines an operating section according to traveling conditions and circumferential conditions, and controls the autonomous vehicle in the second autonomous traveling mode to travel in accordance with the operation by the driver during a period in which the autonomous vehicle is located in the operating section.
