Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If in-vehicle operational equipment is directly connected to both automatic driving control unit and manual driving control unit, then each system can independently control the equipment, but the number of wirings increases and the wiring structure becomes complicated
Solution Approach 1:
An interface control unit is introduced as an intermediary component between the automatic driving control unit, manual driving control unit, and in-vehicle operational equipment. This mediator receives control signals from both control units and routes them to the appropriate equipment, eliminating the need for separate direct connections from each control unit to each piece of equipment. The interface control unit manages signal distribution and prioritization, thereby reducing wiring complexity while maintaining system independence and reliability.
2Adaptability or versatility
If multiple pieces of in-vehicle operational equipment are connected to two different automatic driving systems, then comprehensive control is achieved, but the number of wirings increases correspondingly
Solution Approach 1:
The interface control unit consolidates the control pathways for multiple in-vehicle operational equipment into a single centralized control point. Instead of having separate wiring paths from each control unit to each piece of equipment, the interface control unit merges these pathways, receiving signals from both the automatic driving control unit and manual driving control unit, and distributing them to the equipment. This merging approach maintains comprehensive control coverage while significantly reducing the total number of wirings required.
3Speed
If direct connections are made from each control unit to each piece of equipment, then signal transmission is direct and simple, but the wiring structure becomes excessive and complicated
Solution Approach 1:
The interface control unit serves as a mediator that receives control signals from both the automatic driving control unit and manual driving control unit, and transmits them to the in-vehicle operational equipment. This intermediary approach maintains direct and simple signal transmission within each control path while avoiding the complexity of having multiple direct connections between control units and equipment. The interface control unit efficiently routes signals, preserving transmission speed while simplifying the overall wiring structure.

AI summary
A vehicle driving system is equipped with an automatic driving control unit that outputs a signal for automatically actuating a plurality of pieces of in-vehicle operational equipment that can be operated by a driver, a manual driving control unit that outputs a signal to the pieces of the in-vehicle operational equipment based on an operational input by the driver, and an interface control unit that is connected to the automatic driving control unit, the manual driving control unit and the pieces of the in-vehicle operational equipment, that receives at least one of the signal output from the automatic driving control unit or the signal output from the manual driving control unit, and that outputs the received signal to the pieces of the in-vehicle operational equipment.
