Rotatable Steering Handle Layout for Reduced Cabin Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional steering handles in partially autonomously driving double-track motor vehicles require significant installation space, which is not utilized during autonomous driving, and existing solutions do not efficiently minimize space usage in non-automated driving modes.
Innovation Solution
The steering handle features L-shaped grip elements that can be rotated and positioned to align their gripping sections on a common line, reducing installation space by allowing the grip elements to face each other, with the supporting structure remaining horizontal and the grip elements rotating independently to minimize obstruction during autonomous driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional steering handles are used in partially autonomously driving vehicles, then steering control function is maintained, but installation space is excessively large
Solution Approach 1:
The steering handle is divided into a supporting structure and multiple independently rotatable grip elements. This segmentation allows the grip elements to be positioned independently to minimize space while maintaining steering functionality when needed
Solution Approach 2:
The grip elements are designed to be rotatable relative to the supporting structure, enabling dynamic repositioning. In autonomous mode, grip elements rotate to align with the supporting structure minimizing projection; in manual mode, they can be positioned for optimal gripping
2Volume of moving object
If grip elements are positioned to minimize space during autonomous driving, then installation space is reduced, but steering operation becomes difficult
Solution Approach 1:
The rotatable grip elements can dynamically change position between compact configuration for autonomous driving and extended configuration for manual steering operation
Solution Approach 2:
The angular position parameter of grip elements is changed between two states: aligned with supporting structure for compactness, and angled away for optimal gripping during steering

AI summary
A steering handle of a vehicle includes a support structure, which is mounted for rotation about an axis of rotation and at each end of which an angled gripping element for a hand of a driver is provided such that the gripping element can be rotated relative to the support structure. In at least one defined driving state of the vehicle, the two gripping elements are or have been positioned by way of an actuating device in such a way that portions of the gripping elements that are provided for grasping with the hands of the driver lie on a line, the free ends of the portions facing one another.
