Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle uses fixed speed control during driving, then the control system is simple, but the vehicle cannot adapt to changing surrounding conditions leading to inefficient and potentially unsafe driving operations
Solution Approach 1:
The control system dynamically adjusts speed control signals based on changing surrounding conditions detected by sensors. The processor modifies control parameters in real-time according to detected objects, road conditions, and traffic signals, transforming a static control system into an adaptive one that responds to environmental changes.
Solution Approach 2:
The system continuously receives feedback from object detection units and sensors about surrounding conditions, processes this information, and adjusts speed control signals accordingly. This closed-loop feedback mechanism enables the vehicle to adapt to changing conditions by constantly monitoring and responding to environmental changes.
2Use of energy by moving object
If the vehicle maintains constant speed, then energy consumption is predictable, but the vehicle fails to optimize energy efficiency when encountering intersections, curves, or other road features
Solution Approach 1:
The system performs preliminary actions by detecting upcoming intersections, curves, and other road features in advance using sensors and map data. It proactively adjusts speed control signals before the vehicle encounters these features, optimizing energy consumption by preparing for upcoming conditions rather than reacting after they are encountered.
Solution Approach 2:
The control system changes operating parameters such as speed control signals based on detected surrounding conditions. It adjusts velocity profiles dynamically according to road features, traffic signals, and detected objects, optimizing energy efficiency by matching speed to actual driving conditions rather than maintaining a constant speed.
3Reliability
If the vehicle responds to objects and road features in real-time, then safety and efficiency are improved, but the system complexity and computational requirements increase
Solution Approach 1:
The control system segments the driving environment into distinct zones based on detected objects and road features. It processes and responds to different segments independently - such as intersection zones, curve zones, and straight sections - allowing complex safety responses to be managed through modular, localized control strategies rather than requiring comprehensive real-time analysis of the entire environment.

AI summary
A vehicle driving control apparatus includes an object detection unit configured to detect an object located outside a vehicle; and at least one processor configured to provide a first control signal and a second control signal based on information regarding the object detected by the object detection unit. The at least one processor provides the first control signal and the second control signal by: based on the information regarding the object, providing the first control signal to cause one of an increase or a decrease in a speed of the vehicle during a first time period; and based on the information regarding the object and based on the first control signal provided during the first time period, providing the second control signal to cause the other of the increase or the decrease in the speed of the vehicle during a second time period.
