Joystick Control for Autonomous Vehicle Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous driving technology requires user intervention, which can lead to safety issues when the user needs to switch seats while driving, due to instability in vehicle behavior control.
Innovation Solution
An apparatus and method that utilize a joystick to input adjustment values based on user manipulation, with a controller reflecting these values to control the autonomous vehicle's behavior, including separation distance and lane changes, while sensing user input to prioritize stable vehicle operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If autonomous driving technology is implemented, then user convenience is improved (users can do other business without driving), but vehicle behavior stability deteriorates (current technology is not perfect, requiring user intervention)
Solution Approach 1:
A joystick is introduced as an intermediary device between the user and the autonomous driving system. The joystick provides a physical interface for users to input manipulation amounts, which are then reflected by the controller to adjust vehicle behavior. This mediator allows users to intervene in autonomous driving without requiring full manual control, thus maintaining convenience while improving behavior stability.
2Reliability
If user intervention is allowed in autonomous driving, then vehicle behavior stability is improved, but safety deteriorates (users need to move to driver's seat while driving)
Solution Approach 1:
The joystick serves as a safe intermediary that enables user intervention without requiring physical relocation to the driver's seat. Users can remain in their current position and use the joystick to provide input signals that the controller processes to adjust vehicle behavior, thereby eliminating the safety hazard of seat switching while maintaining behavior stability.
3Adaptability or versatility
If joystick manipulation is used to control vehicle behavior, then user control capability is improved, but device complexity increases
Solution Approach 1:
The joystick is designed with localized functional zones corresponding to different vehicle control functions (steering, acceleration, braking). Each region of the joystick provides specific control capabilities, allowing users to manipulate vehicle behavior in a targeted manner without requiring complex multi-functional interfaces, thus balancing control versatility with device simplicity.

AI summary
An apparatus for controlling a behavior of an autonomous vehicle includes: a joystick that inputs an adjustment value corresponding to an amount of manipulation by a user, and a controller to control the behavior of the autonomous vehicle based on the adjustment value corresponding to the amount of manipulation being input from the joystick.
