Flashing Alert Pictogram for Vehicle Driving Parameter Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for aiding compliance with driving parameters, such as inter-vehicle time, fail to sufficiently alert drivers and clearly inform them of the nature of the alert, as constant visual alerts are not attention-grabbing and erase the graphic representation of the parameter, leading to delayed recognition and management of alerts.
Innovation Solution
A method that uses a flashing alert pictogram to attract attention while retaining the graphic representation of the driving parameter, allowing drivers to quickly identify the alert's nature, with hysteresis to prevent flickering and variable thresholds based on the setpoint value, and frequency of flashing indicating alert severity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a constant visual alert is displayed, then the alert information is continuously presented to the driver, but the driver's attention is not sufficiently attracted and the graphic representation of the driving parameter is erased
Solution Approach 1:
The patent applies periodic action by making the alert pictogram flash alternately with the graphic representation of the driving parameter. This periodic display pattern attracts the driver's attention more effectively than a constant display while ensuring that both the alert information and the driving parameter information are periodically presented, resolving the contradiction between continuous information presentation and driver attention attraction.
2Ease of operation
If the alert display erases the graphic representation of the driving parameter, then the alert pictogram is clearly visible, but the driver's recognition of the alert nature is delayed
Solution Approach 1:
The periodic flashing of the alert pictogram alternates with the display of the graphic representation of the driving parameter, ensuring that both are visible at different moments. This periodic action reduces the driver's recognition time compared to a constant alert display that erases the parameter information, as the parameter graphic reappears regularly to reinforce alert identification.

Function Achieved in This Case
Enhances driver awareness and quick recognition of alerts, reducing the risk of collisions by providing a more effective and comfortable alert system that maintains the graphic representation, thus enabling timely response to critical driving conditions.
Implementation Method 1
the display alternates over time between a graphic representation of the driving parameter and an alert pictogram

AI summary
The invention relates to a method for assisting the driver to respect a threshold for a driving parameter of an n vehicle, comprising, when the actual value of the driving parameter crosses the threshold in a predetermined direction, a visual alert, the visual alert comprising the display on a screen of the vehicle, alternately in time, of a graphic representation (11, 12) of the driving parameter with the presence of an alert pictogram (4) and a graphic representation (2, 3, 10, 11, 12) of the driving parameter without the presence of the alert pictogram (4), so as to make the alert pictogram (4) flash.
