Vehicle Sensor Data Sharing via Geographic Sectoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle sensor systems require each vehicle to be equipped with multiple sensors for detecting environmental parameters, leading to increased costs and space requirements, especially in vehicle fleets.
Innovation Solution
A method where sensor data from one vehicle is transmitted to a motor-vehicle-external data server, which redistributes this information to other vehicles within the same geographic sector, allowing vehicles without specific sensors to access necessary data and optimizing sensor device distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If each vehicle is equipped with multiple sensors for detecting environmental parameters, then measurement precision and reliability are improved, but device complexity and costs increase
Solution Approach 1:
The patent merges sensor resources across multiple vehicles by creating a shared sensor network. Vehicles with sensors (first vehicles) share their detection capabilities with vehicles without sensors (second vehicles) through a server that aggregates and distributes environmental data, eliminating the need for every vehicle to have redundant sensor systems.
Solution Approach 2:
The server acts as a universal platform that serves multiple functions: collecting data from various vehicles, processing and storing environmental information, and distributing relevant data to any vehicle that needs it. This multi-functional system replaces the need for each vehicle to have dedicated sensor systems for every environmental parameter.
2Reliability
If each vehicle is equipped with multiple sensors for detecting environmental parameters, then reliability is improved, but costs increase
Solution Approach 1:
The patent combines sensor resources from multiple vehicles into a shared network. Instead of each vehicle having redundant sensors, the system aggregates sensor data from vehicles that have sensors and makes this data available to all vehicles, thereby maintaining reliability while reducing the total quantity of sensors needed across the fleet.
Solution Approach 2:
The server creates copies of sensor data and distributes them to multiple vehicles. Rather than each vehicle having its own physical sensors, the system digitally replicates and shares sensor information across the vehicle fleet, maintaining data availability without requiring proportional increases in physical sensor quantity.
3Measurement precision
If each vehicle is equipped with multiple sensors for detecting environmental parameters, then measurement precision is improved, but space requirements increase
Solution Approach 1:
The patent merges the spatial footprint of sensor systems across the vehicle fleet. By consolidating sensor hardware in only some vehicles and sharing the data network-wide, the system reduces the cumulative space required for sensors while maintaining comprehensive environmental monitoring capability across all vehicles.
4Device complexity
If sensor data is shared across vehicles, then device complexity is reduced, but loss of information may occur
Solution Approach 1:
The server implements feedback mechanisms to monitor data quality and availability across the network. When sensor data is shared between vehicles, the system tracks data sources, validates information integrity, and can request additional measurements or corrections, ensuring that information loss is minimized while still reducing individual vehicle complexity.

AI summary
The disclosure relates to a method for assisting a user of a first motor vehicle in the operation of the first motor vehicle, which is located in a geographic region. A motor-vehicle-external data server device (16) divides the geographic region into a plurality of geographic sectors. A sensor device of a second motor vehicle, which is also located in the region, detects at least one measurement value, and a control device of the second motor vehicle transmits a sensor signal describing the measurement value to the motor-vehicle-external data server device. The motor-vehicle-external data server device receives a request signal from the first motor vehicle, which, at the time at which the request signal is transmitted, is not prepared to detect a measurement value of the same type. If the motor-vehicle-external data service device determines that the motor vehicles are located within the same geographic sector, the motor-vehicle-external data service device transmits the sensor signal to the first motor vehicle.
