Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-professional drivers struggle to achieve optimal performance while driving on a racetrack due to the lack of effective support in understanding and exploiting the vehicle's limits, as existing driver assistance systems fail to provide clear and intuitive guidance on future engine speed adjustments.
Innovation Solution
A driver assistance system that uses a digital instrument panel to display the current, expected, and optimal engine speed values, with the expected and optimal values projected for a short future time frame, allowing drivers to make intuitive and quantitative corrections to their driving controls.

Engineering Contradiction Analysis
1Productivity
If existing driver assistance systems display only current driving variable values or simple spread indicators, then the system complexity remains low, but the driver cannot achieve optimal performance on racetracks
Solution Approach 1:
The system segments the future engine speed information into two distinct components: expected engine speed (based on current driver input) and optimal engine speed (based on performance models). This segmentation allows the driver to separately understand what will happen if they maintain current input versus what they should aim for, providing clear performance guidance without overwhelming complexity.
Solution Approach 2:
The system performs preliminary calculations of future engine speed values before the driver needs to make decisions. By computing expected and optimal engine speeds ahead of time based on current vehicle state and predicted driver input, the system provides advance guidance that helps the driver achieve optimal performance without real-time complex computations.
2Loss of information
If the system provides detailed future engine speed information, then the driver receives better guidance, but the information becomes less intuitive and harder to interpret
Solution Approach 1:
The system uses color-coded indicators to represent different engine speed states and their relationships. By assigning specific colors to expected versus optimal engine speed values and their comparisons, the system transforms complex numerical data into intuitive visual cues that are easily interpretable by the driver at a glance.
Solution Approach 2:
The system adds a temporal dimension by displaying future engine speed values rather than only current values. This dimensional transformation allows the driver to anticipate upcoming conditions and plan inputs accordingly, converting static speed information into dynamic predictive guidance that enhances intuitiveness.
