Dynamic Vehicle Indicator Positioning for External Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intelligent vehicle technologies are limited in preventing accidents involving pedestrians or other vehicles outside the vehicle, as they primarily focus on notifying the driver and controlling the vehicle based on surrounding situations without effectively communicating with external entities or adapting indicator displays for varying positional relationships.
Innovation Solution
A driver assistance apparatus that includes a communication unit, sensor unit, and indicator output unit, capable of detecting objects around the vehicle, determining positional relationships, and dynamically adjusting indicator displays in terms of position, size, brightness, saturation, and phase to enhance notification accuracy and visibility for both the driver and external parties, such as pedestrians or other vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle uses standard indicator displays, then the device complexity is low, but the notification accuracy and visibility to external parties is insufficient
Solution Approach 1:
The indicator display dynamically adjusts its parameters (position, size, brightness, saturation, phase) based on the detected positional relationship with external objects. This dynamic adaptation enhances notification accuracy without requiring multiple fixed indicator systems, thereby managing device complexity while improving effectiveness.
Solution Approach 2:
The system changes multiple parameters of the indicator display simultaneously (position, size, brightness, saturation, phase) to optimize communication with external parties. This multi-parameter adjustment approach achieves high notification accuracy through a single adaptable indicator system rather than multiple fixed systems.
2Reliability
If the vehicle projects indicators outside to prevent accidents, then the safety of pedestrians and external parties is improved, but the adaptability to varying positional relationships is insufficient
Solution Approach 1:
The indicator projection system adapts its characteristics based on the real-time positional relationship between the vehicle and external objects. The display parameters (position, size, brightness, saturation, phase) are dynamically adjusted to maintain effective communication and safety notifications across varying spatial configurations.
Solution Approach 2:
The system modifies multiple indicator parameters (position, size, brightness, saturation, phase) according to the detected positional relationship with external objects. This enables the safety notification system to adapt to different scenarios such as pedestrians, cyclists, or other vehicles at varying distances and angles.
3Illumination intensity
If the vehicle uses fixed indicator displays, then the ease of operation is high, but the notification visibility to external parties at varying distances is insufficient
Solution Approach 1:
The indicator display automatically adjusts its parameters (position, size, brightness, saturation, phase) based on the detected distance and positional relationship with external objects. This automatic parameter adjustment enhances notification visibility without requiring manual intervention, maintaining ease of operation while adapting to varying viewing conditions.

AI summary
A driver assistance apparatus in a vehicle, and including a sensor configured to detect obstacles around the vehicle; a plurality of indicator output units disposed at different positions on the vehicle; and a processor configured to detect an obstacle around the vehicle and a positional relationship between the vehicle and the obstacle, selectively control the indicator output units to display an indicator outside the vehicle at a position and with a display characteristic, based on the detected positional relationship, detect the positional relationship between the vehicle and the obstacle changing, and selectively control the indicator output units to change at least one of the position and the display characteristic of the indicator based on the changing positional relationship.
