Steering Wheel Display for Vehicle Driver Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle navigation and driver assistance systems lack effective real-time feedback and guidance, especially in unfamiliar or adverse conditions, and do not fully utilize existing vehicle sensors to enhance driver awareness and training for autonomous steering.
Innovation Solution
A steering wheel system with a display and controller that receives vehicle parameters and road characteristics, generating predictions to provide visual and audible messages to the driver, offering guidance on speed, steering, and maneuvers, while integrating with existing sensors like GPS, radar, and LIDAR to enhance driver awareness and training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If simple turn-by-turn icons are displayed on the instrument panel, then the driver receives basic navigation information, but the driver lacks real-time feedback and guidance on speed, steering, and maneuvers
Solution Approach 1:
The patent combines multiple data sources including GPS location, map data, vehicle sensors (accelerometers, gyroscopes, steering angle sensors), and road geometry information into a single integrated navigation system that provides comprehensive real-time feedback on speed, steering, and maneuvers through the steering wheel display
Solution Approach 2:
The steering wheel display serves multiple functions: it shows turn-by-turn navigation icons, provides real-time feedback on driver speed, steering input, and maneuver execution, and delivers training guidance - replacing multiple separate systems with a single multi-functional display
2Extent of automation
If autonomous steering systems are introduced to improve driver assistance, then vehicle autonomy increases, but driver confidence and control understanding decrease
Solution Approach 1:
The system provides continuous real-time feedback to the driver about vehicle position, speed, steering angle, and maneuver execution through the steering wheel display, allowing the driver to understand what the autonomous system is doing and maintain confidence while benefiting from automation assistance
Solution Approach 2:
The steering wheel display acts as an intermediary between the autonomous steering system and the driver, translating complex sensor data and system actions into comprehensible visual feedback that builds driver understanding and confidence in the autonomous system's behavior
3Reliability
If existing vehicle sensors are utilized to provide real-time feedback, then driver awareness and training improve, but system complexity increases
Solution Approach 1:
The system leverages existing vehicle sensors (accelerometers, gyroscopes, steering angle sensors, GPS) that are already part of modern vehicles, allowing the navigation and training system to utilize readily available data without requiring additional expensive sensor installations
Data Source
AI summary
A steering wheel system for a vehicle includes a display and a controller. The controller receives vehicle parameters from one or more vehicle sensors as well as geometric or navigability characteristics of the road. The controller generates a prediction of an effect of the vehicle parameters on the vehicle with respect to the geometric or navigability characteristics of the road. The controller sends a signal to the display based on the prediction. The display is configured to display a representation of the prediction based on the signal received from the controller.
