Dual Radio Interface for Vehicle Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-to-vehicle data communication systems face limitations in transmission capacity and latency, particularly when handling large volumes of data such as video data, which are not adequately addressed by conventional protocols.
Innovation Solution
The implementation of a dual radio interface system, where a first radio interface with a lower transmission capacity is used for periodic status messages and a second radio interface with higher capacity is established for data-intensive transmissions, utilizing pseudonym certificates for addressing and authentication to set up a data communication connection via a 5G mobile radio system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single radio interface with high transmission capacity is used for all data communications, then large volumes of data can be transmitted, but the system complexity and energy consumption increase significantly
Solution Approach 1:
The patent segments the data communication function into two distinct radio interfaces: a first radio interface for periodic status messages and a second radio interface for data-intensive transmissions. This segmentation allows each interface to be optimized for its specific purpose, reducing overall system complexity while maintaining high transmission capacity when needed.
Solution Approach 2:
The apparatus is designed with multi-functionality by incorporating both radio interfaces, allowing it to handle different types of communications (periodic status updates and large data transmissions) through the same device. This enables the system to adapt to varying communication requirements without requiring separate dedicated systems.
2Quantity of substance
If a second radio interface with higher transmission capacity is established for data-intensive transmissions, then large volumes of data can be transmitted efficiently, but the setup time and latency increase
Solution Approach 1:
The system performs preliminary actions by maintaining the first radio interface for periodic status messages, which keeps the communication channel and authentication mechanisms actively maintained. This preliminary presence of the communication infrastructure reduces the setup time when data-intensive transmissions are needed, as the basic connection framework is already in place.
Solution Approach 2:
The first radio interface acts as an intermediary that maintains the communication relationship between vehicles even when not transmitting large data volumes. This intermediary connection allows for faster establishment of the second radio interface for data-intensive transmissions, as the authentication and basic communication protocols are already negotiated through the first interface.
3Reliability
If pseudonym certificates are used for addressing and authentication, then security and reliability are improved, but the processing overhead and communication delay increase
Solution Approach 1:
The patent applies local quality by using pseudonym certificates specifically for the authentication and addressing functions where security is critical, rather than applying complex authentication to all communication aspects. This targeted approach maintains high reliability where needed while minimizing processing overhead in other areas of the communication protocol.

AI summary
An apparatus, method, and computer program for a transportation vehicle for vehicle-to-vehicle data communication by the transportation vehicle. The apparatus for vehicle-to-vehicle data communication by a transportation vehicle includes a first radio interface for the data communication of the transportation vehicle with a further transportation vehicle using a first data communication protocol and with a first transmission capacity; a second radio interface for the data communication of the transportation vehicle with the further transportation vehicle using a second data communication protocol and with a second transmission capacity, wherein the second transmission capacity is greater than the first transmission capacity; and a device for obtaining data messages about a status of transportation vehicles in surroundings of the transportation vehicle via the first radio interface. The data messages include pseudonym certificates for a vehicle-to-vehicle data communication which allow temporary identification of the transportation vehicles in the surroundings of the transportation vehicle.
