Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reliability and availability of driving operation data for road users and infrastructure facilities are limited due to the low percentage of road users equipped with communication means, preventing effective information sharing and utilization.
Innovation Solution
A method where a first motor vehicle equipped with communication devices records and transmits the driving operation data of nearby vehicles using its sensors, expanding the network with environmental sensors like radar or lidar, and radio modules, ensuring data dissemination even if the second vehicle is not equipped with communication technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only vehicles equipped with communication means transmit their driving data, then communication infrastructure requirements are reduced, but the availability and reliability of driving operation data for the network decreases
Solution Approach 1:
A first motor vehicle acts as an intermediary to collect driving operation data from a second motor vehicle using its sensors and transmit this data to the network. This mediator approach allows vehicles without communication equipment to contribute their data through other vehicles that do have communication capabilities, thereby improving data availability without requiring every vehicle to be equipped with communication means.
Solution Approach 2:
The first motor vehicle performs multiple functions: it uses its own sensors to detect the second vehicle, determines the second vehicle's driving operation data, and transmits this data to the network. This multi-functional approach allows a single equipped vehicle to represent multiple vehicles in the network, expanding data coverage without proportionally increasing communication infrastructure requirements.
2Loss of information
If a first motor vehicle determines and transmits driving operation data of a second motor vehicle using its own sensors, then the coverage of available driving data increases, but the energy consumption and communication load of the first vehicle increases
Solution Approach 1:
The first motor vehicle uses its existing sensor systems (radar, lidar, cameras) that are already operational for its own driving functions to simultaneously detect and measure the second vehicle's driving operation data. This self-service approach allows the vehicle to gather additional data without requiring separate dedicated sensors or significantly increasing energy consumption beyond what is already needed for its primary functions.
Solution Approach 2:
The patent combines the data collection function for the second vehicle with the first vehicle's existing sensor operations. By merging these functions, the system achieves expanded data coverage without proportionally increasing energy consumption, as the same sensor infrastructure serves dual purposes.
3Ease of operation
If relative speed data is used directly without conversion to absolute speed, then measurement simplicity is maintained, but the usability of the data for network-wide applications decreases
Solution Approach 1:
The patent transforms the measured relative speed parameter into an absolute speed parameter by combining it with the first vehicle's known absolute speed data. This parameter transformation maintains the simplicity of initial measurement while making the resulting data universally usable for network-wide applications, as absolute speed is a more versatile parameter that can be used by any vehicle in the network regardless of their relative positions.

AI summary
The invention relates to a method for providing driving operation data in a network for the wireless exchange of driving operating data, comprising the following steps: a first motor vehicle connected to the network by communications technology determines the absolute driving operation data of a second motor vehicle by means of at least one environmental sensor disposed with the first motor vehicle, and said absolute driving operation data of the second motor vehicle are transmitted by the first motor vehicle to at least one other subscriber to the network.
