Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driving simulators are limited in simulating real-world environments, making it difficult to effectively evaluate driver response to recommended speed profiles for maximizing fuel economy at signalized intersections, as they lack the capability to provide real-time alerts and data processing for ideal speed adjustments.
Innovation Solution
A system and method that communicate with a driving simulator engine to monitor vehicle speed and traffic signal status, calculate an ideal speed profile for fuel efficiency, and alert drivers through an output device to adjust their speed, ensuring the driver's response is monitored and recorded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving simulators are used to evaluate driver response to recommended speed profiles, then driver safety and training effectiveness are improved, but the ability to provide real-time alerts and data processing for ideal speed adjustments is limited
Solution Approach 1:
A computer system acts as an intermediary between the driving simulator and the speed optimization functions. The system receives virtual speed and position data from the simulator, processes this data to determine ideal speed profiles, and generates alerts to display to drivers. This intermediary architecture enables real-time data processing and alert generation without requiring the driving simulator itself to be overly complex.
Solution Approach 2:
The system divides the overall functionality into separate components: the driving simulator generates virtual environment data, the computer system processes this data and generates speed recommendations, and the alert display system presents information to drivers. This segmentation allows each component to specialize in its function while working together to provide comprehensive eco-driving assistance.
2Ease of operation
If manual engagement is required for fuel-saving analytical tools, then driver awareness and control are improved, but driver response time and fuel economy benefits are reduced
Solution Approach 1:
The system provides continuous feedback to drivers by monitoring their virtual speed and position data, comparing it to the ideal speed profile, and generating real-time alerts when adjustments are needed. This feedback loop enables drivers to make timely speed adjustments without requiring manual engagement with complex controls, as the system automatically processes data and presents clear guidance.
Solution Approach 2:
The system performs self-service by automatically receiving data from the driving simulator, processing this data to determine ideal speed profiles, and generating appropriate alerts without requiring manual driver input. The driver simply needs to observe the alerts and make natural driving adjustments, combining automated processing with manual driving control.
3Device complexity
If driving simulators operate without integrated speed optimization engines, then simulator simplicity and cost are maintained, but fuel economy optimization and emission reduction capabilities are lost
Solution Approach 1:
The system merges the driving simulator with speed optimization and alert generation functionalities by integrating these components through a computer system that receives data from the simulator and provides feedback. This combination enables fuel economy optimization and emission reduction capabilities while maintaining relative simplicity through modular integration rather than requiring a completely new complex system.

AI summary
Disclosed is a system and method for generating a vehicle speed alert in a driving simulation system that communicates with a remote driving simulator engine and a remote speed optimization engine. The remote speed optimization engine receives data from the vehicle speed alert system after the vehicle speed alert system has received data from the remote driving simulator engine, including the vehicle's simulated distance to a signalized intersection, the time remaining for the simulated traffic light to change, and the current simulated light status (green, yellow, red) of the traffic light. The vehicle speed alert system then receives from the remote speed optimization engine a recommended speed profile for that given instant, and if the driver's current speed does not fall within some maximum difference with the current recommended speed profile, calculates and transmits an alert to an output device to alert the driver of action necessary to achieve the recommended speed profile.
