Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack effective methods to provide vehicles with accurate and comprehensive information about vulnerable road users (VRUs) such as pedestrians and cyclists, which is crucial for safe navigation and collision avoidance, especially in complex environments with varying road conditions and weather.
Innovation Solution
A cloud-based server calculates vehicle-specific bounding boxes around VRUs, considering information from the VRUs, vehicles, and ancillary data like road conditions and weather, and provides these dimensions to the vehicles for improved path planning and collision avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cloud-based server calculates vehicle-specific bounding boxes using multiple data sources, then measurement precision of VRU detection is improved, but device complexity of on-board units is reduced
Solution Approach 1:
A cloud-based server acts as an intermediary between VRU detection systems and vehicles. The server receives data from multiple sources including ancillary data sources, performs complex bounding box calculations, and provides results to vehicles. This mediator approach enables accurate VRU detection without requiring complex processing capabilities in on-board units.
2Productivity
If cloud-based server processes VRU detection data, then productivity of safety calculations is improved, but use of energy by on-board units is reduced
Solution Approach 1:
The patent extracts the computationally intensive processing functions from on-board units and relocates them to a cloud-based server. The on-board unit retains only essential functions for receiving and acting on bounding box data, significantly reducing energy consumption while maintaining high productivity in safety calculations through the server's processing power.
3Reliability
If vehicle-specific bounding boxes are provided to each vehicle, then reliability of collision avoidance is improved, but quantity of data transmitted is increased
Solution Approach 1:
The patent applies local quality by providing customized, vehicle-specific bounding box information to each individual vehicle based on its specific location, orientation, and detection needs. Rather than broadcasting generic data to all vehicles, the system tailors the data to each vehicle's specific context, improving collision avoidance reliability while minimizing unnecessary data transmission.

AI summary
Disclosed are techniques for wireless communication. In a first aspect, a network entity may calculate dimensions of a bounding box surrounding a vulnerable road user (VRU) in a vicinity of an approaching vehicle. The network entity may provide the dimensions of the bounding box to the approaching vehicle. In a second aspect, a vehicle on-board unit (OBU) may receive, from a network entity, dimensions of a bounding box surrounding a VRU in a vicinity of the vehicle. The OBU may use the bounding box for VRU safety calculations and collision avoidance.
