Autonomous Vehicle Handover Controls to Reduce Manual Input Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in manual driving mode control due to complex and inconvenient joystick devices, which can lead to erroneous operations during emergency situations.
Innovation Solution
An integrated control apparatus with a movable control device for steering, gear-shifting, acceleration, and braking, and a fixed touch-type display device for other functions, allowing users to easily switch between autonomous and manual driving modes without complex manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a joystick device with multiple buttons, levers, and switches is used for manual control, then the vehicle can be controlled in manual driving mode, but the manipulation becomes difficult and inconvenient, and erroneous operations may occur
Solution Approach 1:
The control device is segmented into two separate components: a movable control device held in the hand for primary control functions, and a fixed display device for secondary functions. This segmentation allows each component to have a simplified, focused interface rather than consolidating all controls in one complex joystick, thereby improving ease of operation while maintaining necessary functionality.
2Adaptability or versatility
If multiple control functions are integrated into a single joystick, then comprehensive control is achieved, but the risk of erroneous operations increases
Solution Approach 1:
By dividing control functions between the movable control device (held in hand) and the fixed display device, the patent reduces the likelihood of erroneous operations. The movable device handles critical functions with intuitive controls, while the fixed device manages less critical functions through touch interface, creating natural separation that prevents accidental activation of multiple functions simultaneously.
Solution Approach 2:
The fixed display device acts as an intermediary between the user and certain control functions. Rather than having all controls directly on the joystick, the display device mediates access to secondary functions through touch interface, providing a buffer that reduces direct manipulation errors while maintaining comprehensive control capability.
3Ease of operation
If a fixed display device is separated from the movable control device, then touch-type manipulation for secondary functions is enabled, but the overall device structure becomes more complex
Solution Approach 1:
The patent segments the control system into movable and fixed components, each with optimized interfaces. The fixed display device provides touch manipulation for secondary functions, while the movable control device handles primary controls. This segmentation, while increasing structural elements, distributes complexity across separate components rather than concentrating it, improving overall ease of operation.

AI summary
An integrated control apparatus for an autonomous vehicle includes: a movable control device corresponding to a portable device that performs steering, gear-shifting, acceleration, and braking of a vehicle by a user's control when a driving mode is shifted from an autonomous driving mode to a manual driving mode; and a fixed display device controlled in a touch manner to perform other functions other than steering, gear-shifting, acceleration, and braking, wherein a steering dial switch, a gear-shifting slide switch, an acceleration rotary switch, and a brake button switch are disposed in the movable control device and are manipulated differently.
