Vehicle Display Control for Multi-Object External Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle state display systems struggle to appropriately notify multiple objects, such as pedestrians and other vehicles, around a vehicle, especially when their intentions and positions are complex or overlapping, leading to potential safety hazards.
Innovation Solution
A vehicle control device with a peripheral object recognition unit, an object state recognition unit, and a display control unit that analyzes the positions and intentions of multiple objects around the vehicle to execute targeted external notification processing, adjusting alert levels and messages based on recognized states, including distance, direction, and intentions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display device notifies all detected objects uniformly, then the notification coverage is comprehensive, but the notification accuracy and relevance to each object's specific situation deteriorates
Solution Approach 1:
The notification system is segmented into different notification types (alert notification, information notification, encouragement notification) that are selectively applied to different objects based on their states. The display control unit divides the notification task into multiple categories and assigns appropriate notification types to each object individually, rather than applying a single uniform notification to all objects.
Solution Approach 2:
Different notification qualities and intensities are applied to different objects based on their specific situations. For example, alert notifications with higher intensity are used for objects in dangerous situations, while information notifications with lower intensity are used for objects in safe situations. This ensures each object receives notifications tailored to its specific context.
2Loss of information
If the display device provides detailed notifications for each object's specific state, then the notification relevance improves, but the information processing complexity and energy consumption increases
Solution Approach 1:
The system applies detailed state analysis and customized notifications only to objects that require such attention based on their risk levels. For low-risk objects, simplified notifications are used, while for high-risk objects, comprehensive state analysis and detailed customized notifications are applied. This partial application of complex processing reduces overall energy consumption while maintaining information relevance where needed.
Solution Approach 2:
The notification parameters (type, intensity, content) are dynamically changed based on object states such as distance, movement direction, and detected intentions. The system adjusts notification parameters in real-time according to the specific situation of each object, providing relevant information without consistently maintaining high processing levels for all objects.
3Measurement precision
If the display device notifies multiple objects simultaneously with different messages, then the individual object notification accuracy improves, but the control complexity and potential for notification errors increases
Solution Approach 1:
The control process is segmented into distinct steps: detecting object states, determining notification types, and executing notifications. Each object's notification is determined and executed as a separate task within this segmented framework, reducing control complexity while maintaining precision in state recognition and notification delivery.
Solution Approach 2:
The system performs preliminary detection and classification of object states before generating notifications. By pre-identifying object states (distance, movement direction, detected intentions) and categorizing them, the system simplifies the subsequent notification generation process and reduces the complexity of real-time control decisions.
