EV Efficiency Gauge with Peer Comparison Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers of hybrid electric vehicles, plug-in electric vehicles, and battery electric vehicles often fail to achieve desired fuel economy or energy efficiency due to their driving habits, as they lack the necessary knowledge and tools to translate recommended techniques into actual changes in behavior, and existing information displays overwhelm them with excessive information.
Innovation Solution
An information display system that includes a controller communicating with a display to show an energy consumption gauge featuring an average efficiency indicator and a peer efficiency indicator, allowing drivers to visualize their efficiency relative to peers, providing a competitive incentive to improve driving habits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If comprehensive information displays are provided to drivers, then drivers have access to more vehicle operation data, but drivers become overwhelmed and cannot effectively translate information into improved driving habits
Solution Approach 1:
The display system segments information by presenting only the most critical efficiency metrics to the driver, rather than overwhelming with all available data. The system divides complex vehicle operation information into simplified, actionable visual cues that drive behavior change without causing information overload.
Solution Approach 2:
The system applies local quality by providing targeted, context-specific information at the moment it is most relevant to the driver. Rather than displaying all information uniformly, the system selectively presents efficiency feedback based on current driving conditions and historical performance, making the information both complete and usable.
2Loss of information
If detailed efficiency metrics are displayed, then drivers receive comprehensive feedback on their driving performance, but drivers cannot effectively translate this information into improved driving habits
Solution Approach 1:
The system implements continuous feedback by comparing real-time driving efficiency against historical performance and peer averages. This feedback loop provides drivers with actionable insights that directly guide behavior modification, transforming abstract efficiency metrics into concrete driving habit improvements.
Solution Approach 2:
Rather than presenting raw efficiency data and expecting drivers to interpret it, the system inverts the approach by presenting interpreted, actionable recommendations directly. The system tells drivers what to do differently based on their efficiency metrics, reversing the traditional information delivery model to improve behavior change effectiveness.
3Loss of information
If multiple gauges and indicators are provided, then drivers have access to comprehensive vehicle operation information, but drivers cannot effectively use this information to improve fuel economy or energy efficiency
Solution Approach 1:
The system extracts only the most critical efficiency indicators from the full set of available vehicle data, presenting them in a simplified format that drivers can immediately understand and act upon. By taking out only the essential information needed for behavior change, the system maintains information availability while dramatically improving actionability.

AI summary
An information display system includes a display including an energy consumption gauge having a bar. The display system includes a controller in communication with the display and configured to instruct the display to include an average efficiency indicator relatively arranged on the bar based on a calculated driver efficiency value, and instruct the display to include a peer efficiency indicator relatively arranged on the bar based on a peer efficiency value.
