Movable Steering Wheel for Autonomous Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current semi-autonomous and fully autonomous vehicle systems lack a clear and intuitive interface for switching between manual and autonomous steering modes, leading to driver confusion and difficulty in transitioning control between the two modes.
Innovation Solution
A vehicle steering system that utilizes a movable steering wheel to signal the autonomous driving electronic control unit, allowing the driver to seamlessly transition between manual and autonomous modes by moving the wheel between two planes, with a single or double concentric wheel configuration, where the steering wheel serves as the interface to engage or disengage the autonomous steering system.

Engineering Contradiction Analysis
1Extent of automation
If a classic steering wheel is used in autonomous mode, then the vehicle can operate autonomously, but the steering wheel rotates vigorously causing driver distraction and confusion
Solution Approach 1:
The steering wheel is designed to be movable between two planes: in the first plane, it functions as a classic steering wheel for manual control; in the second plane, it disengages from the steering mechanism to prevent vigorous rotation during autonomous operation. This dynamic reconfiguration allows the same component to serve different functions based on operating mode, eliminating driver distraction while maintaining autonomous capability
2Device complexity
If no interface is provided for mode switching, then the system structure can be simplified, but the transition between manual and autonomous modes becomes difficult and unclear
Solution Approach 1:
The steering wheel itself serves as the mode switching interface. By moving the steering wheel to the second plane, the driver directly engages/disengages autonomous mode without requiring separate buttons, switches, or complex controls. The primary control component performs the dual function of steering (in manual mode) and mode selection (when moved to second plane), eliminating the need for additional interface elements while providing intuitive control
