Vehicle Actuator Sensitivity Adjustment via Profile Mimicry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The responsiveness of different vehicles can vary significantly, making it difficult for drivers to adapt when switching between them, leading to safety concerns and complicating the learning process for new drivers.
Innovation Solution
A computer-implemented system that adjusts the sensitivity of vehicle actuators based on a received vehicle profile, allowing the first vehicle to mimic the responsiveness of a second vehicle by modifying the response of actuators to user control inputs, thereby providing a consistent driving experience across different vehicles.

Engineering Contradiction Analysis
1Adaptability or versatility
If different vehicles maintain their original distinct responsiveness characteristics, then each vehicle preserves its unique handling identity and performance characteristics, but drivers experience difficulty adapting when switching between vehicles leading to safety concerns
Solution Approach 1:
The system dynamically adjusts actuator responsiveness in real-time based on the loaded vehicle profile, transforming static vehicle characteristics into adaptive, changeable parameters. This allows the vehicle to switch between different responsiveness states depending on which driver is operating it, thereby improving adaptability without compromising safety through consistent, predictable behavior patterns.
Solution Approach 2:
The system changes key responsiveness parameters of vehicle actuators (steering, braking, acceleration) by loading pre-measured profile data that defines optimal parameter values for each driver-vehicle combination. This allows quantitative adjustment of responsiveness characteristics to match driver expectations and improve both adaptability and safety.
2Ease of operation
If vehicle actuators are modified to mimic another vehicle's responsiveness, then a consistent driving experience is achieved across different vehicles, but the system complexity increases due to profile management and actuator control mechanisms
Solution Approach 1:
The system creates simplified digital copies of vehicle responsiveness characteristics by measuring and storing actuator response data in profile formats. These profile copies can be transferred and applied to different vehicles, providing consistent driving experiences without requiring complex physical modifications. The copying approach abstracts the complexity into manageable data structures.
Solution Approach 2:
The vehicle responsiveness adjustment system serves multiple functions: it can load profiles from different sources (original vehicle, rental fleet, simulation data), support multiple driver preferences, and work across different vehicle types. This multi-functionality justifies the added complexity by providing broad ease of operation benefits across various scenarios.
3Measurement precision
If detailed actuator response data is collected and stored for each vehicle profile, then accurate responsiveness matching is achieved, but the data storage and processing requirements increase
Solution Approach 1:
The system extracts only the essential responsiveness characteristics from complete actuator data sets, isolating the key parameters that most significantly impact driving feel and safety. By taking out only the critical data elements needed for responsiveness matching, the system achieves accurate profile creation with reduced data storage requirements compared to preserving complete raw data sets.

AI summary
One example of a computer-implemented method of adjusting vehicle sensitivity comprises receiving, at a first vehicle, a vehicle profile of a second vehicle. The vehicle profile of the second vehicle correlates measured responses of one or more actuators on the second vehicle to measured user control inputs on the second vehicle. The method further comprises receiving a user control input for the first vehicle; and modifying a response of one or more actuators on the first vehicle to the received user control input based on the received vehicle profile of the second vehicle such that the one or more actuators on the first vehicle mimic the one or more actuators on the second vehicle.
