Engineering Contradiction Analysis
1Reliability
If V2X communication is used to receive movement information of multiple forward vehicles, then driving safety and convenience are improved, but the system complexity increases
Solution Approach 1:
The system segments the complex task of forward vehicle monitoring by dividing it into distinct functional modules: a receiving unit that collects movement information from multiple forward vehicles through V2X communication, a sensor unit that detects specific forward vehicles, and a control unit that processes the data. This segmentation allows each module to handle specific aspects of the problem independently, improving reliability while managing system complexity through modular architecture.
Solution Approach 2:
The control unit serves multiple functions: it calculates driving paths based on movement information from multiple forward vehicles, determines specific forward vehicles to follow, and adjusts the subject vehicle's driving actions accordingly. This multi-functionality consolidates what could be separate systems into a single control unit, improving reliability through integrated decision-making while avoiding the complexity of multiple independent control systems.
2Measurement precision
If movement information of multiple forward vehicles is received and processed, then driving path accuracy is improved, but the information processing time increases
Solution Approach 1:
The system continuously receives and pre-processes movement information from multiple forward vehicles through V2X communication before it is strictly needed for path calculation. The receiving unit maintains a current state of forward vehicle positions and movements, so when the control unit needs to calculate a driving path, the data is already prepared and available, reducing real-time processing time while maintaining high path accuracy.
Solution Approach 2:
Instead of directly processing raw movement information from multiple vehicles in real-time, the system uses sensors to create simplified representations (copies) of forward vehicle states. The sensor unit detects specific forward vehicles and creates processed data that captures essential movement characteristics, which the control unit then uses for path calculation. This copying approach reduces the complexity and time required for processing while preserving the accuracy needed for safe driving decisions.

AI summary
A vehicle control system includes a receiving unit to receive movement information of a plurality of forward vehicles on a road on which a subject vehicle is driven through V2X communication; a sensor to sense a specific forward vehicle, from among the plurality of forward vehicles, that is driven ahead of the subject vehicle; and a control unit to calculate a driving path for the subject vehicle based on the movement information of the plurality of forward vehicles received by the receiving unit and to control driving of the subject vehicle to follow the driving path or the specific forward vehicle.
