Adjustable Driver Display Using Head Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle vision systems lack the ability to dynamically adjust displays based on the driver's head position and gaze direction, and they do not effectively enhance image data for navigation and object detection using augmented reality overlays, while also failing to provide secure access and authorization systems.
Innovation Solution
A vehicle vision system that includes cameras and electronic control units (ECUs) to detect the driver's head position and gaze direction, adjust display orientations, process image data for enhanced navigation, and utilize biometric sensors for secure access and authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display orientation is fixed, then the device complexity is reduced, but the driver comfort and usability deteriorate when head position varies
Solution Approach 1:
The display orientation is made dynamically adjustable based on detected driver head position. The system continuously monitors head position and automatically adjusts display orientation to maintain optimal viewing angles, transforming a static display into a dynamic one that adapts to driver movements.
Solution Approach 2:
The system uses the driver's own head position data to automatically adjust the display orientation without requiring manual intervention. The display self-adjusts based on sensor input, eliminating the need for manual controls while improving comfort.
2Loss of information
If basic image processing is used, then the processing speed is faster, but the navigation information completeness deteriorates
Solution Approach 1:
The image processing is divided into separate functional modules: basic processing for speed-critical path detection, and enhanced processing for navigation overlay generation. This segmentation allows different processing levels to operate in parallel, maintaining speed while adding comprehensive navigation information.
Solution Approach 2:
The system dynamically adjusts processing intensity based on driving conditions. During normal driving, basic processing maintains speed, while during navigation events, enhanced processing with AR overlays is activated to provide complete navigation information when needed.
3Reliability
If no access authorization system is implemented, then the device complexity is reduced, but the vehicle security deteriorates
Solution Approach 1:
A biometric sensor acts as an intermediary between the driver and the vehicle system. The sensor verifies driver identity and authorization before enabling system access, providing security without requiring complex manual authentication mechanisms.
Solution Approach 2:
The access authorization system automatically verifies driver identity using biometric sensors and grants or denies access without manual intervention. The system self-manages authentication, reducing the complexity of user interaction while maintaining high security standards.

AI summary
A vehicular driver assist system includes a sensor disposed at a vehicle and a display disposed at the vehicle and viewable by a driver of the vehicle. An electronic control unit (ECU) includes a processor for processing sensor data captured by the sensor to detect presence of objects in the field of view of the sensor. The vehicular driver assist system, responsive to processing by the processor of sensor data captured by the sensor, determines presence of a driver of the vehicle and determines a position of the driver's head. The vehicular driver assist system, responsive to determining the position of the driver's head, adjusts an orientation of the display based on the determined position of the driver's head to increase visibility of the display for the driver.
