Vehicle Knob Range Switching for Manual and Autonomous Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle systems lack the ability to dynamically adjust the operating range of a knob based on vehicle mode conversion, limiting intuitive control of various vehicle functions.
Innovation Solution
A system that includes an input interface, memory, and processor to receive input information related to vehicle driving modes, store programs for controlling knob operating ranges, and execute these programs to vary the knob's operating range based on mode changes, such as from manual to autonomous driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the knob operates within a fixed operating range, then the device structure is simple, but the adaptability to different vehicle modes is limited
Solution Approach 1:
The patent implements a dynamic operating range adjustment mechanism where the knob's operational range is no longer fixed but adapts based on vehicle mode. The control unit receives vehicle mode information and dynamically adjusts the operating range parameters, allowing the same physical knob to serve different functions in different modes (manual vs autonomous driving), thereby resolving the contradiction between simplicity and adaptability
Solution Approach 2:
The system changes the operational parameters of the knob based on vehicle mode. The control unit modifies the operating range parameters (such as angular limits, velocity constraints) according to the detected vehicle mode, enabling the knob to control different sets of functions in different modes without requiring physical structural changes
2Adaptability or versatility
If the knob operating range is fixed, then the control system is simple, but the functionality coverage is limited
Solution Approach 1:
The patent makes the knob a universal control interface that can perform multiple functions across different vehicle modes. By dynamically adjusting the operating range, the single knob controls various functions including steering assistance in manual mode and entertainment system in autonomous mode, achieving multi-functionality without adding multiple control devices
Solution Approach 2:
The control unit continuously receives feedback about the vehicle mode and adjusts the knob's operating range accordingly. This closed-loop feedback mechanism ensures the knob always operates within the appropriate range for the current mode, enabling expanded functionality coverage while maintaining simple control through automatic adaptation

AI summary
A system for controlling knob operating ranges in a vehicle mode conversion, and a method therefor are provided. The system includes: an input interface to receive input information related to a vehicle driving mode; a memory to store instructions of a program for controlling an operating range of a knob based on the input information; and a processor electrically connected to the memory. The processor, upon execution of the instructions of the program, transmits a control command to vary the operating range of the knob allocated to an area of an in-vehicle display, based on the input information for detachment of a passenger seat entertainment display and conversion to an autonomous driving mode.
