Dual Joystick Touch Control for Autonomous Vehicle Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous vehicle systems lack an efficient method to control dual joystick levers based on user input and driving mode changes, which can lead to safety issues and accidents.
Innovation Solution
A dual integrated control apparatus with touch sensors for each joystick lever, allowing only one lever to be activated when touched while the other is deactivated, and switching between activation states based on driving mode changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dual joystick levers are provided for manual driving mode, then ease of operation is improved, but risk of accidental operation increases
Solution Approach 1:
The system dynamically changes the operational state of joystick levers based on driving mode. In autonomous driving mode, both levers are deactivated; when manual mode is selected, only one lever is activated at a time. This dynamic state change prevents accidental operation while maintaining ease of operation when needed.
Solution Approach 2:
The system changes the functional parameter of the joystick levers from deactivated to activated state based on driving mode selection. By controlling which lever is functional (first lever or second lever) based on mode changes, the system reduces accidental operation risk while preserving operational capability.
2Ease of operation
If both joystick levers are activated simultaneously, then ease of operation is improved, but control reliability deteriorates
Solution Approach 1:
The system implements dynamic control where only one joystick lever is activated at any given time during manual driving mode. The activation state switches between first lever and second lever based on operational requirements, preventing simultaneous activation and ensuring control reliability.
Solution Approach 2:
The control apparatus provides feedback control by monitoring the state of both joystick levers and automatically determining which one should be activated. This feedback mechanism ensures that only one lever controls the vehicle at a time, maintaining reliability while preserving ease of operation.
3Ease of operation
If joystick levers are always in popped-up state, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The joystick levers are designed to be movable between popped-up and folded states. During autonomous driving mode, they remain folded to simplify the control interface. When manual mode is activated, they pop up to provide ease of operation. This dynamic positioning reduces device complexity while maintaining operational accessibility.
