3D Spatial Audio Alerts for Faster Vehicle Hazard Awareness

Solution Overview

Problem

Current vehicle safety systems provide inadequate alerts for drivers, relying on auditory cues that require visual confirmation, leading to driver distraction and inefficient hazard detection.

Innovation Solution

A method utilizing processing circuitry to generate three-dimensional stereo sound alerts based on data from vehicle sensors, conveying hazard characteristics such as location and threat level directly to the driver, minimizing the need for visual confirmation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional auditory alerts are used, then the system is simple and easy to implement, but the driver must visually confirm hazards which causes distraction and reduces detection efficiency

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent transitions from traditional 2D speaker alerts to a 3D spatial audio system that provides directional sound alerts matching the actual location of hazards. This dimensional enhancement allows drivers to intuitively understand hazard position without visual confirmation, improving detection efficiency while maintaining operational simplicity through natural spatial perception

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The system introduces an intermediary processing layer that analyzes sensor data, determines hazard characteristics, and generates directional audio alerts. This intermediary translates raw sensor information into intuitive spatial sound cues that convey both hazard presence and location, eliminating the need for visual confirmation while keeping the driver's focus on the road

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If visual confirmation is required for hazard detection, then the driver can accurately identify hazards, but the driver becomes distracted from the road

Engineering Contradiction:
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the visual-mechanical confirmation process with an acoustic information system. Directional audio alerts convey hazard location and characteristics through sound spatial cues, allowing drivers to identify hazards accurately through hearing alone without the time loss associated with visual confirmation and lane position adjustments

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs preliminary hazard analysis and spatial audio generation before the driver needs to react. By pre-processing sensor data and creating directional audio alerts that immediately convey hazard location and threat level, the system eliminates the delay between hazard detection and driver awareness, maintaining accurate identification while reducing reaction time loss

Inventive Principle:
Principle #10Preliminary action

3Loss of information

If three-dimensional stereo sound alerts are implemented, then hazard information is conveyed more effectively, but the system complexity increases

Engineering Contradiction:
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments hazard information into distinct spatial audio components that correspond to different hazard characteristics. Each sensor's directional data is processed independently to create specific spatial cues, allowing the system to convey multiple hazard attributes (location, distance, threat level) through segmented audio channels that can be processed and generated by modular system components

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system employs a universal processing framework that handles multiple hazard types and sensor inputs through a common directional audio generation algorithm. This multi-functional approach allows the same core system to process data from various sensors (cameras, radar, LIDAR) and generate appropriate spatial alerts for different hazard scenarios, reducing overall system complexity through consolidation rather than requiring separate systems for each function

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present disclosure relates to a method, apparatus, and computer-readable storage medium for providing three-dimensional stereo sound to a vehicle to promote active safety and awareness to hazards. For instance, the present disclosure describes a method for providing three-dimensional stereo sound comprising receiving data signals from sensors positioned around an exterior of a vehicle, detecting a hazard based on the received data signals, determining characteristics of the detected hazard, generating an alert based on the determined characteristics of the detected hazard, and outputting the generated alert as the three-dimensional stereo sound via speakers arranged around an interior of the vehicle, the outputted alert communicating to a driver of the vehicle the determined characteristics of the detected hazard.
