Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous driving system operates without communication with adjacent vehicles and pedestrians, then device complexity is reduced, but safety and reliability deteriorate due to unexpected accidents
Solution Approach 1:
The navigation system is extended to perform dual functions: traditional route guidance and vehicle-to-vehicle/vehicle-to-pedestrian communication. The same navigation display and processing units are used to both guide the autonomous vehicle and communicate its intentions to surrounding road users, eliminating the need for separate dedicated communication hardware and reducing overall system complexity while improving safety
Solution Approach 2:
The server acts as an intermediary that receives autonomous driving information from the vehicle's navigation system and redistributes it to adjacent vehicles and pedestrians. This mediator approach allows the autonomous vehicle to communicate indirectly with surrounding road users through a centralized platform, reducing the complexity of direct peer-to-peer communication systems while maintaining reliable safety information exchange
2Reliability
If autonomous driving system provides comprehensive driving information to all road users, then safety improves, but information processing load and system complexity increase
Solution Approach 1:
The complex task of information processing and distribution is extracted from the autonomous vehicle's onboard system and relocated to an external server. The vehicle's navigation system only needs to send raw autonomous driving information to the server, which then handles the complex processing of translating, formatting, and distributing this information to various road users in appropriate formats, reducing the vehicle's information processing load while maintaining comprehensive safety communication
Solution Approach 2:
The server serves as an intermediary that manages the complexity of information processing between the autonomous vehicle and multiple road users. It receives unified autonomous driving information from the vehicle, processes this information centrally, and distributes it to adjacent vehicles and pedestrians in appropriate formats, thereby reducing the information processing burden on the vehicle's onboard systems while ensuring comprehensive safety communication
3Productivity
If autonomous driving system communicates real-time driving information to adjacent vehicles, then traffic flow efficiency improves, but communication bandwidth requirements and system complexity increase
Solution Approach 1:
The navigation system's communication capabilities are used for multiple purposes: traditional route guidance to the driver and real-time information exchange with adjacent vehicles and pedestrians. By making the navigation system multi-functional, the patent avoids adding dedicated communication hardware and software, thereby improving traffic flow efficiency through real-time information sharing without proportionally increasing communication system complexity
Solution Approach 2:
The server acts as a communication mediator that manages bandwidth and information distribution efficiently. It receives autonomous driving information from the vehicle once and redistributes it to multiple adjacent vehicles and pedestrians, avoiding redundant transmissions and optimizing bandwidth utilization. This intermediary approach enables improved traffic flow efficiency through comprehensive real-time communication while minimizing the actual communication load and system complexity

AI summary
An autonomous driving control apparatus and method using navigation technology are disclosed. The autonomous driving control apparatus includes a driving mode setting unit, a navigation unit, and an information provision unit. The driving mode setting unit sets the driving mode of a vehicle. The navigation unit offers guidance on a driving route to a destination input by the driver of the vehicle based on the set driving mode. The information provision unit, if the driving mode of the vehicle is set to autonomous driving mode, provides the navigator of an adjacent vehicle and the navigator of the terminal of a pedestrian with autonomous driving information received from the vehicle, and also provides the navigation unit with behavior information received from the adjacent vehicle and the terminal of the pedestrian.
