Vehicle Communication Infrastructure Dynamic Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle communication infrastructures are designed for worst-case scenarios, leading to inefficient resource utilization and increased costs, as they cannot dynamically adapt communication behavior to varying situations, limiting functional scope and increasing energy consumption and pollutant emissions.
Innovation Solution
A method that evaluates current vehicle situations to prioritize and adjust communication data streams, using network management to optimize communication behavior by selectively switching off or reducing non-essential data streams in favor of safety-critical ones, implemented through an adaptive network switching element that couples vehicle buses to control units via interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication infrastructure is designed for worst-case scenarios, then system reliability is improved, but resource utilization efficiency deteriorates and costs increase
Solution Approach 1:
The patent implements dynamic adaptation of communication behavior by continuously evaluating the current situation and adjusting communication parameters in real-time. The system transitions from static worst-case design to dynamic situation-aware communication, where communication resources are allocated based on actual needs rather than predetermined maximum requirements.
Solution Approach 2:
The system changes communication parameters (data volume, priority, communication frequency) based on evaluated situation parameters. By dynamically adjusting these parameters according to actual operational conditions, the system achieves both reliability and efficiency without being constrained by worst-case design assumptions.
2Reliability
If the communication infrastructure is designed for worst-case scenarios, then system reliability is improved, but costs increase
Solution Approach 1:
The dynamic evaluation and adaptation mechanism allows the system to maintain reliability through situation-appropriate communication while avoiding the excessive resource allocation and associated costs of static worst-case design. The system adapts its communication behavior to match actual requirements, reducing unnecessary resource provisioning costs.
3Quantity of substance
If all control units communicate with maximum data simultaneously, then communication completeness is improved, but energy consumption increases
Solution Approach 1:
The system applies partial action by transmitting only the necessary amount of communication data required for the current situation rather than maximum data volume. The evaluation mechanism determines the appropriate level of communication activity, enabling the system to maintain communication completeness when needed while reducing energy consumption during normal operations.
Solution Approach 2:
The continuous situation evaluation creates periodic assessment cycles that dynamically adjust communication data volume. This periodic adaptation ensures that communication occurs at appropriate intervals and intensities based on actual system needs, avoiding continuous maximum data transmission and associated energy waste.
4Adaptability or versatility
If communication resources are allocated for all possible functions, then functional scope is improved, but resource efficiency deteriorates
Solution Approach 1:
The system dynamically allocates communication resources based on the evaluated current situation and priority assessments. Rather than statically provisioning resources for all possible functions simultaneously, the system adaptively activates communication resources according to actual operational requirements, achieving both functional versatility and resource efficiency.
Solution Approach 2:
The patent applies local quality by assigning different priority levels and communication characteristics to different data streams based on their specific importance and requirements. Safety-critical communications receive higher priority and guaranteed resources, while non-critical communications are dynamically adjusted, creating locally optimized communication quality throughout the system.

AI summary
To dynamically adapt the communication behaviour of a communication infrastructure on the basis of parameters or states, a current driving situation, a vehicle state or a traffic situation is assessed. On the basis of the assessment, a decision is made regarding whether communication data streams need to be adapted. If such adaptation is necessary, the decision is conveyed in order to switch off individual network subscribers (3) fully or in part and to dispossess them of data capacity for their communication data streams.
