Solution Overview
Problem
Existing vehicle control systems are not customizable to individual user driving habits, leading to inefficient engine or brake response, as they are typically designed for a general user rather than specific driving styles.
Innovation Solution
A control system that includes a variable input control, a vehicle control unit, and a memory storage device to record and adjust power delivery based on user inputs, allowing for personalized power profiles to be created and updated, ensuring that commonly used power settings are centered within the control range, optimizing power delivery for each user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control pedals are designed for general use, then they can serve any user, but they cannot optimize response for individual driving habits
Solution Approach 1:
The system performs preliminary actions by recording user pedal inputs and power deliveries over time before making adjustments. The controller stores historical data of pedal positions and corresponding power deliveries, then uses this accumulated data to automatically adjust control parameters, eliminating the need for manual customization while adapting to individual driving habits.
Solution Approach 2:
The system implements feedback by continuously monitoring user pedal inputs and power deliveries, then using this information to automatically adjust control parameters. The controller receives feedback from sensors measuring pedal position and power delivery, processes this data to identify user preferences, and adjusts the control system accordingly, creating a closed-loop adaptive system.
2Speed
If pedal displacement is made small for rapid response, then aggressive drivers get better control, but gradual acceleration users lose precision
Solution Approach 1:
The system applies dynamics by making the control response characteristics adjustable and adaptive rather than fixed. The controller dynamically modifies the relationship between pedal displacement and power delivery based on recorded user behavior patterns, allowing the same physical pedal travel to produce different response characteristics depending on the user's typical driving style and preferences.
Solution Approach 2:
The system changes parameters by adjusting control parameters such as the mapping between pedal position and power delivery based on analyzed user driving habits. The controller modifies these parameters automatically to optimize both response speed and control precision for each individual user, resolving the contradiction between aggressive and gradual driving preferences.
3Ease of operation
If control positions are fixed to power levels, then the system is simple to operate, but it cannot adapt to user preferences
Solution Approach 1:
The system practices self-service by automatically recording, analyzing, and adjusting to user driving preferences without requiring manual intervention. The controller autonomously monitors pedal inputs and power deliveries, identifies user patterns, and modifies control parameters to match individual preferences, making the system both simple to operate and highly adaptive simultaneously.

AI summary
This application discusses various ways to adjust the performance of a variable input control in accordance with previous use data. In some embodiments, the previous use data can be associated with particular users of the variable input control. In this way, a response provided by the user input control can be adjusted to accommodate particular patterns of use on a user by user basis. In some embodiments, the variable input control can take the form of an accelerator pedal of a vehicle. Performance of the accelerator pedal can be adjusted by changing an amount of engine power provided for a particular accelerator pedal position. The adjustment can arrange commonly utilized power settings in the middle of the accelerator pedal range of motion to make manipulation of the accelerator pedal more comfortable and convenient for each user of the accelerator pedal.
