Driver Assistance Display for Real-Time Sensor Data Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems (ADAS) primarily focus on conveying system operation information rather than actively engaging drivers with comprehensive sensor data, limiting their ability to induce safe driving practices.
Innovation Solution
A driver assistance display apparatus that includes a display, image obtainer, distance detector, and controller to provide notification information based on road images, surrounding objects, and vehicle data, displaying critical information such as lane axes, risk of understeer or impact, and obstacle proximity in real-time, using various display modes like HUD, cluster, or augmented reality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing driver assistance systems use simple warning sounds or guide sounds to convey system operation information, then the system operation can be indicated to the driver, but the information about multiple sensors received in the actual vehicle is limitedly expressed to the driver
Solution Approach 1:
The patent transitions from one-dimensional audio warnings to multi-dimensional visual display by projecting sensor data onto the windshield through HUD technology. This allows comprehensive expression of multiple sensor information (lane position, distance to other vehicles, road conditions) simultaneously in the driver's field of view, resolving the limitation of simple warning sounds while maintaining manageable system complexity through integrated processing.
Solution Approach 2:
The display apparatus integrates multiple sensor data types (camera, radar, LIDAR) and processing functions (image recognition, distance calculation, lane detection) into a single unified display system. This multi-functional approach allows the system to express comprehensive vehicle environment information through one integrated HUD display rather than requiring separate systems for each sensor type.
2Reliability
If the driver assistance system provides comprehensive sensor data and real-time road condition information to the driver, then driver awareness and safe driving can be improved, but the system requires multiple sensors and complex processing capabilities
Solution Approach 1:
The patent combines multiple sensors (camera, radar, LIDAR) and their processing functions into an integrated driver assistance system that feeds unified information to the HUD display. This merging approach maintains comprehensive sensor data collection for improved driving safety while reducing overall system complexity through centralized processing and a single display interface rather than multiple separate warning systems.
Solution Approach 2:
The HUD display acts as an intermediary that receives and processes data from multiple sensors, then presents synthesized information to the driver in an intuitive format. This intermediary layer integrates complex sensor data (image recognition, distance measurement, lane detection) into comprehensible visual cues on the windshield, maintaining high reliability while managing system complexity through centralized information processing.
3Loss of information
If the system displays detailed notification information about road conditions and vehicle states in real-time, then driver awareness is enhanced, but the processing and display resources are consumed
Solution Approach 1:
The system extracts and prioritizes only the most critical driving information from multiple sensors for display on the HUD, such as lane position, distance to other vehicles, and immediate road conditions. This selective extraction approach transmits essential safety information to the driver while minimizing processing energy consumption by not displaying all available sensor data simultaneously.
Solution Approach 2:
The display system implements partial action by showing only the most relevant sensor information needed for safe driving at any given moment, rather than processing and displaying all available data. This approach enhances driver awareness with critical information while conserving processing energy by avoiding unnecessary computation and display of non-essential data.
