Programmable Vehicle Input Mapping for Hard-to-Reach Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle input systems lack an efficient method to suggest and associate auxiliary input devices with frequently used vehicle functions that have low accessibility scores, making it difficult for users to control these functions effectively.
Innovation Solution
A system that includes a first auxiliary input device and a touchscreen human-machine interface, where the system provides selectable input options for controlling vehicle functions and suggests associating the auxiliary input device with vehicle functions based on historical use and accessibility scores, allowing users to easily access frequently used but hard-to-reach functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system provides multiple control input options for vehicle functions, then the functionality and control options are improved, but the complexity of the input system increases
Solution Approach 1:
The auxiliary input device is designed to be programmable and adaptable, allowing a single physical device to control multiple different vehicle functions. The system provides universality by enabling the auxiliary input device to serve various purposes through software configuration rather than requiring dedicated controls for each function.
Solution Approach 2:
The system creates a virtual mapping between the auxiliary input device and touchscreen control options. When a user programs the auxiliary input device for a specific function, the system copies the control capability from the touchscreen interface to the auxiliary device, allowing the same function to be accessed through multiple input methods.
2Ease of operation
If the system suggests associations based on historical use data, then the ease of operation is improved, but the loss of information increases due to data processing requirements
Solution Approach 1:
The system performs preliminary analysis of historical use data to pre-calculate and suggest optimal function associations before the user needs to program the auxiliary input device. By analyzing past usage patterns in advance, the system prepares ready-made suggestions that simplify the programming process and reduce the cognitive load on users.
Solution Approach 2:
The system continuously monitors and analyzes historical use data to provide feedback suggestions for function associations. This feedback mechanism allows the system to learn from user behavior patterns and automatically suggest the most useful mappings, improving ease of operation while managing data processing requirements through iterative refinement.

AI summary
A system for a vehicle includes a first input device and a second input device that provides a plurality of selectable input options. The plurality of selectable input options comprises a plurality of control input options for controlling a plurality of vehicle functions and an association input option for associating the first input device with at least one vehicle function suggested from among the plurality of vehicle functions. The at least one vehicle function is suggested based on historical use of the control input option that controls the at least one vehicle function and an accessibility score of the control input option.
