Vehicle Energy Consumption Map for Predicted Route Deviation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle infotainment systems lack the ability to provide a high-definition energy consumption map, which would allow drivers to predict and visualize the energy status of their vehicle along planned or deviated drive paths, potentially leading to situations where the vehicle runs out of battery or fuel.
Innovation Solution
An in-vehicle control and display system that generates and displays a high-definition energy consumption map, incorporating latitudinal, longitudinal data, and predicted energy consumption data, allowing drivers to view the estimated energy levels at different points along their drive path, including planned and deviated routes.

Engineering Contradiction Analysis
1Loss of information
If typical maps are displayed by IVI systems, then traffic data and navigation data are provided, but energy consumption information is not available
Solution Approach 1:
The patent combines energy consumption data with traditional map data by integrating it into the existing map display system. The energy consumption map merges geographical information (latitudinal and longitudinal data) with predicted energy consumption data, allowing both navigation and energy information to be displayed together on a single integrated map interface rather than requiring separate systems.
Solution Approach 2:
The map display system is enhanced to serve multiple functions: it continues to provide traditional navigation and traffic information while simultaneously displaying predicted energy consumption data along different drive paths. This multi-functional approach allows the same display system to convey both route guidance and energy management information without requiring additional dedicated hardware.
2Reliability
If energy consumption data is added to the map, then driver awareness of energy levels is improved, but the computational requirements increase
Solution Approach 1:
The system performs preliminary calculations of energy consumption by predicting energy levels at various points along planned drive paths before the actual journey begins. By pre-computing energy consumption data for different routes and scenarios, the system reduces the need for complex real-time calculations during vehicle operation, thereby lowering instantaneous computational power requirements while maintaining prediction accuracy.
Solution Approach 2:
The patent utilizes changes in vehicle parameters (such as speed, acceleration, route conditions) to dynamically adjust energy consumption predictions. By monitoring and responding to parameter changes rather than performing continuous full-scale simulations, the system maintains accurate energy predictions while optimizing computational resource usage through event-driven updates.
3Ease of operation
If real-time energy consumption predictions are provided, then driver experience is enhanced, but the system complexity increases
Solution Approach 1:
The patent introduces an intermediary layer that processes raw vehicle data and route information to generate simplified energy consumption predictions. This intermediary processing layer acts as a mediator between the complex vehicle systems and the user interface, translating detailed technical data into comprehensible energy consumption information that can be easily displayed and understood by drivers without requiring them to interpret complex system data.
Data Source
AI summary
An in-vehicle control system for providing an energy consumption map for a vehicle is provided. The method includes displaying, on a display of a computing system of the vehicle, a map of an environment external to the vehicle. The map includes a predicted drive path extending between an initial location of the vehicle and a final destination of the vehicle within the environment. The method further includes generating, by the computing system, and based on the predicted drive path, a prediction of the energy consumption of the vehicle along the one or more trajectories of the predicted drive path, and displaying, on the display of the computing system, the predicted energy consumption of the vehicle along the one or more trajectories of the predicted drive path. The predicted energy consumption of the vehicle is displayed so as to at least partially overlay the predicted drive path.
