AR Driving Assistance 3D Display for Low-Latency Road Hazard Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Advanced Driver Assistance Systems (ADAS) face challenges in providing effective driving assistance on complex road conditions such as snowy or muddy surfaces, with limited solutions for adaptive information display, natural viewing experiences, and high latency, leading to inadequate support for drivers in challenging environments.
Innovation Solution
The implementation of an Augmented Reality (AR) method and apparatus that determines driving assistance information in real-time during vehicle travel and displays virtual 3D information, using sensors and GPS to sense road conditions, adaptively select information, and reduce latency by employing head-mounted or vehicle-mounted displays to present information in a natural and timely manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional ADAS displays are used, then information can be provided to drivers, but the display is not timely and causes latency in critical driving situations
Solution Approach 1:
The system performs preliminary detection and processing of driving information using multiple sensors (cameras, radar, LIDAR) to identify potential hazards before they become critical threats, allowing early warning and preventive action
Solution Approach 2:
The patent introduces an intermediary processing system that aggregates data from multiple sensors, processes it through AI algorithms, and presents synthesized information to the driver, reducing the cognitive load and response time compared to raw sensor data
2Loss of information
If comprehensive driving information is displayed, then driver awareness is improved, but the device complexity increases
Solution Approach 1:
The system employs multiple sensors (cameras, radar, LIDAR, ultrasonic sensors) that serve multiple functions - detecting various types of obstacles, road conditions, and environmental factors simultaneously, reducing the need for separate specialized devices
Solution Approach 2:
The patent creates virtual representations of the driving environment through 3D mapping and digital twins of road scenes, allowing the system to analyze and display comprehensive information without requiring physical duplication of sensing equipment
3Ease of operation
If adaptive information display is implemented, then user experience is improved, but the difficulty of detecting and measuring road conditions increases
Solution Approach 1:
The system continuously monitors driver behavior, vehicle state, and environmental conditions, adjusting the type, amount, and presentation of information displayed in real-time based on feedback from these sources, optimizing the user experience dynamically
Solution Approach 2:
The patent changes multiple parameters including display brightness, information density, warning intensity, and notification frequency based on detected road conditions, vehicle speed, and driver state, making the system adaptable to varying operational contexts
