Spatiotemporal Wave Display for Vehicle Speed Deviation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous driving scenarios, there is a lack of intuitive and unconscious methods for drivers to monitor and respond to deviations between set and actual vehicle speeds, particularly in environments where visual cues are not readily available.
Innovation Solution
A method and system that utilize spatiotemporal patterns displayed within the vehicle to indicate speed deviations, where the frequency and direction of wave patterns convey the magnitude and direction of speed differences between set and actual speeds, allowing for intuitive monitoring without requiring conscious comparison.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional digital displays showing set speed and current speed are used, then speed information is provided to the driver, but the driver must consciously compare the two values which increases cognitive load and reduces ease of operation
Solution Approach 1:
The patent uses color changes in the spatiotemporal display to indicate speed deviation. The display transitions between different colors (e.g., green, yellow, red) based on the magnitude and direction of speed deviation from the set speed, allowing drivers to intuitively understand speed status without conscious numerical comparison
Solution Approach 2:
The patent employs periodic wave patterns that oscillate at frequencies corresponding to speed deviation magnitude. The waves continuously propagate and repeat, creating a dynamic visual representation where the rhythm and frequency of the waves convey speed information intuitively through temporal patterns rather than static numbers
2Extent of automation
If autonomous driving systems operate without driver monitoring, then automation level increases, but drivers lose awareness of speed deviations which reduces safety
Solution Approach 1:
The patent implements a feedback mechanism where the spatiotemporal display continuously provides visual feedback about speed deviation to the driver. The display responds in real-time to changes in actual versus set speed, creating an intuitive feedback loop that maintains driver awareness even during autonomous operation without requiring active monitoring
Solution Approach 2:
The system provides self-service by automatically generating and displaying the spatiotemporal pattern that represents speed deviation. The display serves itself by converting numerical speed data into an intuitive visual format without requiring driver intervention or conscious processing, maintaining awareness passively
3Measurement precision
If numerical speed displays are used, then precise speed information is provided, but the display lacks intuitiveness and requires conscious cognitive processing
Solution Approach 1:
The patent transforms the one-dimensional numerical speed data into a two-dimensional spatiotemporal visual pattern. The speed deviation is represented through both spatial dimensions (wave amplitude, position) and temporal dimension (frequency, rhythm), creating a multi-dimensional representation that is intuitively perceivable while maintaining precise information
Solution Approach 2:
The patent changes the parameter representation from numerical values to physical wave parameters. The speed deviation magnitude is encoded in wave frequency and amplitude, while direction of deviation is encoded in wave propagation direction, making the information intuitively detectable through human sensory processing rather than cognitive numerical comparison

AI summary
Arrangements described herein can display a set speed deviation for a vehicle using spatiotemporal patterns. A set speed and an actual speed for a vehicle can be acquired. A deviation between the set speed and the actual speed of the vehicle can be determined. Responsive to determining the deviation between the predetermined set speed and the actual speed, a spatiotemporal pattern can be displayed within the vehicle. The spatiotemporal pattern can indicate to a user the deviation between the set speed and the actual speed via the spatiotemporal pattern. In one or more arrangements, the spatiotemporal pattern can be a repeating wave pattern.
