Engineering Contradiction Analysis
1Speed
If decentralized processing using mobile devices is implemented, then response speed and reliability are improved, but device complexity increases
Solution Approach 1:
Each mobile device independently performs collision risk assessment using its own sensors and processing capabilities, without requiring centralized server processing. The device self-generates movement profiles, probability profiles, and collision risk assessments locally, enabling rapid response while distributing computational complexity across multiple devices rather than concentrating it in a central system.
2Measurement precision
If LIDAR is used for distance and speed measurements, then measurement precision is improved, but system cost and complexity increase
Solution Approach 1:
The system combines data from multiple sensor types including LIDAR, cameras, and other detection devices to create comprehensive movement profiles. By merging information from different sensor modalities, the system achieves high measurement precision while distributing the functional requirements across multiple components rather than relying on a single complex system.
3Measurement precision
If probability profiles are superimposed for collision assessment, then collision prediction accuracy is improved, but computational requirements increase
Solution Approach 1:
The system calculates probability profiles for multiple potential collision scenarios simultaneously by superimposing movement profiles of different traffic participants. This partial action approach computes only the necessary probability assessments for relevant collision risks rather than exhaustive analysis of all possible scenarios, achieving high prediction accuracy while managing computational energy consumption.

AI summary
A method for avoiding a collision between at least one first traffic participant and at least one second traffic participant. A first movement profile is assigned to the first traffic participant, wherein a second movement profile is assigned to the second traffic participant, wherein a first probability profile is generated from the first movement profile and a second probability profile is generated from the second movement profile, and the probability profile comprises information relating to the probability of the location of the respective traffic participant at a time in the future, characterized in that a collision probability is determined in a mobile device by superimposing the first probability profile and the second probability profile, wherein the probability profile is determined as a probability cone in space.
