Steering Wheel Button Mapping for Eyes-On-Road Cockpit Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cockpit systems lack an efficient and safe method for users to operate diversified functions without diverting their gaze or hands from the steering wheel, compromising driving safety and convenience.
Innovation Solution
A cockpit function operation method utilizing buttons on the steering wheel, where one button (mode switch) binds and controls multiple functions, and another (function operation) adjusts parameters through varied operations, supplemented by a display for feedback, allowing users to manage functions without looking away or moving their hands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple buttons are added to control diversified cockpit functions, then the adaptability and functionality are improved, but the device complexity increases
Solution Approach 1:
The first button is designed to perform multiple functions: it can switch between different cockpit functions (air conditioning, multimedia, navigation) and also adjust parameters within each function. This multi-functional design eliminates the need for separate dedicated buttons for each function, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The button configuration is made dynamic through software control rather than fixed hardware assignments. The first button can be dynamically reconfigured to control different functions based on user selection, allowing the system to adapt to diverse cockpit functions without adding physical buttons.
2Ease of operation
If traditional control methods are used requiring hand and gaze movement, then the ease of operation for each function is improved, but the driving safety deteriorates
Solution Approach 1:
The patent merges the function selection and parameter adjustment operations into a single button (the first button). Users can switch between functions and adjust parameters using only the first button without moving their hand to different locations or taking their gaze from the road, thus maintaining ease of operation while improving driving safety.
Solution Approach 2:
The system provides self-service through voice recognition and automatic function binding. The electronic device automatically binds the second button to the selected function from the first button's operations, reducing the need for manual configuration and allowing users to operate functions with minimal hand movement while maintaining safety.
3Adaptability or versatility
If more cockpit functions are added, then the adaptability is improved, but the ease of operation deteriorates due to increased complexity
Solution Approach 1:
The first button serves as a universal control for all cockpit functions, handling both function switching and parameter adjustment. This multi-functional approach allows diverse cockpit functions to be controlled through a single interface, maintaining operation simplicity despite increased function diversity.
Solution Approach 2:
The electronic device acts as an intermediary that automatically binds the second button to the function selected via the first button. This automatic binding mechanism simplifies operation by eliminating the need for users to manually configure each function's control assignments, allowing diverse functions to be operated simply through the established button bindings.

AI summary
A cockpit function operation method is provided. The method may be applied to a vehicle. The vehicle includes a steering wheel. A first button and a second button may be disposed on the steering wheel. In response to a first user operation on the first button, the vehicle may bind the second button to a first cockpit function. In response to a second user operation on the second button, the vehicle may control the first cockpit function. In response to a third user operation on the first button, the vehicle may switch a cockpit function bound to the second button from the first cockpit function to a second cockpit function. In response to a fourth user operation on the second button, the vehicle may control the second cockpit function.
