Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If server apparatuses are used to assist in travel control, then processing load on the vehicle is reduced, but communication delay and instability occur when base stations are switched
Solution Approach 1:
The system performs preliminary actions by collecting and processing detection data from multiple base stations before the vehicle switches between them. The server apparatus maintains a history of detection data and performs prediction in advance, so when base station switching occurs, the vehicle can continue travel control without interruption or loss of stability.
Solution Approach 2:
The system implements feedback mechanisms where the server apparatus receives detection data from the vehicle, processes it, and returns travel control assistance information. The feedback loop includes continuous monitoring of base station switching events and adjustment of prediction models based on actual vehicle behavior during transitions.
2Speed
If data is processed on the vehicle side, then control response is faster, but the vehicle requires extensive processing power and sensors
Solution Approach 1:
The travel control processing is segmented into two parts: detection data collection is performed on the vehicle side using its sensors, while heavy computational processing including prediction and travel control assistance is performed on the server apparatus side. This segmentation allows the vehicle to maintain fast response by only handling data collection, while the server handles complex computations.
Solution Approach 2:
The server apparatus acts as an intermediary between the vehicle's detection system and the travel control execution system. It receives detection data from the vehicle, processes it through prediction models, and returns control assistance information, thereby reducing the processing burden on the vehicle while maintaining control responsiveness.
3Adaptability or versatility
If base station switching is frequent during vehicle movement, then communication coverage is improved, but communication stability and data continuity deteriorate
Solution Approach 1:
The server apparatus performs preliminary actions by collecting detection data from multiple base stations before the vehicle switches between them. It maintains a history of detection data and performs prediction in advance, so when base station switching occurs, the vehicle can continue travel control without interruption or loss of stability.
Solution Approach 2:
The system prepares for base station switching by maintaining a buffer of detection data and prediction results from multiple base stations. This cushioning allows the vehicle to seamlessly transition between base stations without losing data continuity or experiencing control interruptions.

AI summary
In a travel control assistance system in which server apparatuses assist in a travel control of automobiles, the automobiles each includes a travel controller and a vehicle communication unit. The travel controller carries out the travel control based on detection data by a vehicle sensor. The vehicle communication unit acquires data regarding the travel control from the server apparatus. The server apparatuses as an entirety include individual assistance units corresponding to the respective automobiles, and a high-order assistance unit. The high-order assistance unit collects data regarding the automobiles from the individual assistance units, and generates high-order assistance data for the travel control. The high-order assistance unit offers the generated data to the individual assistance units. The individual assistance units each generates data for the travel control of the corresponding automobile based on the data and the high-order assistance data, and transmits the generated data to the vehicle communication unit.
