Driving Aid Trajectory Envelope and Obstacle Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driving assistance methods do not clearly indicate to drivers whether they risk colliding with detected obstacles, requiring drivers to interpret complex representations and deduce their approach or avoidance maneuvers.
Innovation Solution
A driving aid method that determines the angular position of the steering wheel, captures images of the environment, detects obstacles, and displays a graphical representation of the vehicle's trajectory and obstacle position, using visual signals to indicate the risk of collision based on distance and trajectory alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a representation of the trajectory and environment is displayed, then the driver can see the obstacle position, but the driver cannot clearly determine if collision risk exists without complex analysis
Solution Approach 1:
The patent extracts the critical collision risk information from the complex trajectory and environment representation, separating it as a distinct visual indicator. The system identifies when an obstacle intersects with the vehicle trajectory and highlights this specific risk condition independently from other environmental data, allowing the driver to immediately perceive collision danger without analyzing the entire complex representation.
Solution Approach 2:
The patent employs color changes in the visual indicator to communicate collision risk levels. Different colors represent different risk states (e.g., green for safe, yellow for caution, red for high risk), enabling the driver to quickly understand the collision situation through intuitive color coding rather than complex graphical analysis.
2Loss of information
If the driver must deduce approach or avoidance maneuvers from complex representations, then all trajectory information is provided, but the ease of operation decreases
Solution Approach 1:
The patent implements feedback by providing real-time visual indicators that directly show the relationship between vehicle trajectory and obstacle position. The system continuously updates the indicator to reflect current collision risk based on steering wheel position and vehicle movement, giving the driver immediate feedback on whether the current trajectory poses a risk and what maneuver adjustments are needed.
Solution Approach 2:
The patent segments the complex trajectory information into distinct visual elements: the vehicle trajectory path, obstacle position, and collision risk indicator. This segmentation allows the driver to focus on the critical collision risk element without being overwhelmed by the complete trajectory data, reducing interpretation effort while maintaining full information availability.

AI summary
The invention relates to a method for aiding driving for a driver of an automotive vehicle, comprising the following steps: a) determination of the angular position of the steering wheel of said automotive vehicle (P1); b) detection of the presence of an obstacle in proximity to the automotive vehicle (Q1); c) determination of a trajectory of the automotive vehicle at least on the basis of the angular position of the steering wheel (P2) and determination of a quantity relating to the position of the obstacle detected in step b); d) simultaneous display on a screen of the automotive vehicle of an envelope representative of the trajectory of said vehicle and of an indicator representative of the relative position of the obstacle detected in step b) with respect to the automotive vehicle (R2).
