Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If numerous sensors and computational devices are provided on CAV to improve automated driving functions, then the functional capabilities are improved, but the costs and device complexity increase significantly
Solution Approach 1:
The patent introduces a roadside intelligent unit (RIU) as an intermediary between the vehicle and the collaborative automated driving system. The RIU performs sensing, prediction, planning, and control functions externally, allowing the vehicle to access advanced automated driving capabilities without carrying complex onboard sensors and computational devices. This mediator approach resolves the contradiction by externalizing the complexity while maintaining functionality.
2Adaptability or versatility
If numerous sensors and computational devices are provided on CAV to improve automated driving functions, then the functional capabilities are improved, but the costs increase significantly
Solution Approach 1:
The RIU serves as a shared infrastructure resource that multiple vehicles can access. By externalizing the expensive sensing and computational resources to roadside infrastructure, individual vehicles avoid the high costs of equipping each vehicle with complete automated driving systems, thereby reducing manufacturing costs while maintaining advanced functionality.
3Adaptability or versatility
If the vehicle is equipped with complete automated driving system to improve functional capabilities, then the intelligence level is improved, but the device complexity and burden on vehicle system increase
Solution Approach 1:
The patent extracts the complex sensing, prediction, planning, and control functions from the vehicle onboard system and relocates them to the roadside intelligent unit. The vehicle only retains basic communication and execution capabilities, while the RIU handles the intellectually intensive tasks. This extraction resolves the contradiction by separating the complexity from the vehicle system.
4Ease of manufacture
If the vehicle uses basic control system to reduce device complexity, then the ease of manufacture is improved, but the functional capabilities for complex driving scenarios are insufficient
Solution Approach 1:
The RIU acts as an external brain that compensates for the vehicle's simple onboard system. Through communication interfaces, the RIU provides the vehicle with access to advanced automated driving functions including long-tail scenario handling, while the vehicle itself maintains a simple and cost-effective control system architecture.
