Vehicle Lighting Control Using Remote Pedestrian Position Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-pedestrian communication systems require special communication devices, increasing costs and complexity, and are limited by detection range, concealment, and weather issues, as well as the need for real-time data processing.
Innovation Solution
A method using general Internet technologies to collect and process global position data from pedestrians and cyclists via GPS-enabled devices or stationary cameras, storing data in a remote computer unit for later use by a vehicle's computer unit to control lighting and warning systems, eliminating the need for direct communication between pedestrians/cyclists and vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated communication devices are deployed for vehicle-pedestrian communication, then road safety can be improved, but system complexity and costs increase
Solution Approach 1:
The patent introduces a remote server as an intermediary that collects position data from pedestrians and cyclists via their mobile devices and makes this data available to vehicles. This mediator approach allows vehicle-pedestrian communication without requiring direct communication devices in vehicles, thereby improving road safety while avoiding the complexity of deploying dedicated communication systems in each vehicle.
Solution Approach 2:
The patent leverages the universal presence of mobile devices with GPS functionality that pedestrians and cyclists already carry for other purposes. By making these existing devices serve the additional function of position reporting for safety applications, the system improves road safety without requiring specialized equipment, thus avoiding increased device complexity.
2Difficulty of detecting and measuring
If camera-based detection is used to identify pedestrians, then detection capability can be improved, but reliability decreases due to detection range limitations, obscuration, and weather conditions
Solution Approach 1:
The patent replaces camera-based optical detection with GPS-based position data collection. Instead of using optical systems (cameras) that are limited by detection range, obscuration, and weather conditions, the system uses satellite-based GPS positioning that provides reliable position information regardless of these environmental factors, thereby improving detection reliability while maintaining capability.
3Speed
If real-time position data processing is implemented, then response speed can be improved, but system complexity increases
Solution Approach 1:
The patent extracts the complex real-time data processing function from the vehicle system and places it on a remote server. The vehicle simply queries and receives pre-processed position data from the server, which handles the complex real-time processing of data from multiple pedestrians and cyclists. This extraction approach enables fast response speed while avoiding the complexity burden on the vehicle system.

AI summary
The invention relates to a method for activating at least one device (12) from a motor vehicle. In the method, the at least one device (12) is activated by the vehicle at least as a function of global position data of at least one pedestrian (F1, F2, F3) and/or at least one cyclist (R1, R2). According to the invention, the position data of the at least one pedestrian (F1, F2, F3) and/or the at least one cyclist (R1, R2) is transmitted to a remotely located computer unit (10) and made available to a computer unit (11) of the motor vehicle. In this way, the activation of the at least one device (12) as a function of the position data of pedestrians and/or cyclists is possible in a simple and economic way.
