Vehicle Operating Strategy Profile via Global and Local Data Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles lack an optimized operating strategy profile that adapts to specific driving routes, leading to inefficiencies in energy consumption, emissions, and comfort, as existing methods rely on pre-defined strategies that do not account for real-time conditions such as traffic, weather, and vehicle status.
Innovation Solution
A method and device that transmit driving route data to a central database to receive a geo-referenced global operating strategy profile, which is combined with sensor-acquired local data to determine a tailored operating strategy profile, optimizing parameters like energy consumption, power output, and comfort by selecting or adjusting strategies based on predefined criteria and conditions.

Engineering Contradiction Analysis
1Device complexity
If pre-defined operating strategies are used, then device complexity is reduced, but adaptability to specific driving routes and real-time conditions deteriorates
Solution Approach 1:
The operating strategy profile is segmented into multiple independent components: a global operating strategy profile obtained from a central database based on driving route data, and a local operating strategy profile determined from sensor-based acquisition of real-time operating data. These segments are independently obtained and then combined to form the final operating strategy, allowing each segment to be optimized separately while maintaining overall system manageability.
Solution Approach 2:
The global operating strategy profile is obtained in advance from a central database before the vehicle journey begins. This preliminary action allows the system to prepare route-specific operating strategies based on empirical data from multiple vehicles, so that when the vehicle is in operation, the strategy can be quickly combined with real-time local data without requiring complex real-time calculations.
2Use of energy by moving object
If route-specific operating strategies are implemented, then energy consumption is reduced, but device complexity increases
Solution Approach 1:
A central database device acts as an intermediary between multiple vehicles and the operating strategy system. This intermediary collects, processes, and stores empirical operating data from multiple vehicles, then provides pre-processed global operating strategy profiles to individual vehicles. This intermediary approach distributes the computational complexity to the central database rather than requiring each vehicle to perform complex real-time analysis.
Solution Approach 2:
The system uses sensor-based acquisition to automatically obtain local operating data and deterministically determines the local operating strategy profile without requiring manual intervention. The vehicle's control system automatically combines the global and local profiles and applies the resulting operating strategy, making the system self-sufficient once initialized.
3Reliability
If empirical data from multiple vehicles is used, then operating strategy optimization is improved, but information processing complexity increases
Solution Approach 1:
The central database creates a replicated copy of the aggregated empirical data and processing logic across the network. Each vehicle receives a copy of the global operating strategy profile relevant to its route, rather than all vehicles sharing a single centralized processing system. This copying approach distributes the data processing load and allows parallel operation of multiple vehicles with optimized strategies.
Solution Approach 2:
The system transforms raw empirical operating data from multiple vehicles into standardized operating strategy profiles with specific parameters optimized for different driving routes. By changing the parameters from raw data to structured strategy profiles with defined characteristics (energy consumption, emissions, comfort), the system makes the data more useful while reducing processing complexity at the vehicle level.

AI summary
A method and a device for specifying an operating strategy profile for the operation of a motor vehicle, and a method and a central database device for specifying a global geo-referenced operating strategy profile with regard to a driving route are provided.
