Dynamic Vehicle Response Tuning via Auxiliary Driver Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles often have factory-calibrated settings that do not align with individual driver preferences regarding vehicle response and performance, leading to a desire for personalized tuning.
Innovation Solution
A vehicle system that includes primary and auxiliary human-machine interface devices, along with a dynamic tuning service, allows drivers to adjust vehicle response and performance by modifying calibration parameters in real-time based on auxiliary input, using sensors and machine learning to create personalized driving profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If factory calibration is used to achieve baseline vehicle response acceptable to broad segment, then general acceptability is improved, but individual driver preference alignment deteriorates
Solution Approach 1:
The system dynamically adjusts calibration parameters in real-time based on driver input from auxiliary HMI devices. The control module modifies vehicle response characteristics on-the-fly, transitioning from static factory calibration to dynamic adaptive calibration, allowing the same vehicle to adapt to different driver preferences without physical reconfiguration
Solution Approach 2:
The system changes calibration parameters (such as steering ratio, stability control thresholds, or suspension stiffness) based on driver preferences. By adjusting these parameters dynamically, the vehicle can provide different response characteristics for the same physical configuration, resolving the contradiction between general acceptability and individual preference
2Ease of operation
If default factory calibration is applied, then system simplicity is maintained, but driver preference customization capability deteriorates
Solution Approach 1:
The system enables drivers to self-customize their preferred vehicle response characteristics through auxiliary HMI devices. Drivers can independently adjust calibration parameters to match their preferences without requiring dealer intervention or complex setup procedures, making the customization process as easy as default operation
Solution Approach 2:
The control module serves multiple functions: it processes primary driver commands for vehicle control, processes auxiliary inputs for calibration adjustment, and dynamically adjusts vehicle response characteristics. This multi-functionality allows the same system to provide both ease of operation and customization capability
3Adaptability or versatility
If auxiliary HMI device is added for dynamic tuning, then driver preference customization is improved, but system complexity increases
Solution Approach 1:
The system merges the primary HMI device (steering wheel) and auxiliary HMI device (tuning controls) into a unified control architecture. Both devices interface with the same control module that handles vehicle commands and calibration adjustments, reducing overall system complexity compared to having separate independent systems

AI summary
Vehicles and related systems and methods are provided for assisting operation of a vehicle by enabling dynamic tuning of vehicle responsiveness. One method involves obtaining an auxiliary driver input indicative of an auxiliary driver command to influence responsiveness of the vehicle from an auxiliary human-machine interface device different from a primary human-machine interface device for receiving primary driver input indicative of a driver command to influence a trajectory of the vehicle. In response to the auxiliary driver input, a relationship between a vehicle state command and the driver input is adjusted based on the auxiliary driver input, wherein an actuator control system operates one or more actuators of the vehicle in accordance with the adjusted vehicle state command to influence the trajectory of the vehicle responsive to the primary driver input.
