Autonomous Vehicle Driving Behavior Modification via Passenger Preferences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack the ability to adjust driving style based on passenger preference, leading to a disconnect in control and unpredictability, as current systems do not accommodate individual desires for driving behavior.
Innovation Solution
A system and method that allow passengers to interact with autonomous vehicles through interfaces, such as mobile devices or central computing systems, to modify driving behavior by setting preferences for speed, comfort, and other parameters, which are then processed by onboard computers to adjust the vehicle's operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If autonomous vehicles use fixed driving behavior settings, then system complexity is reduced, but adaptability to different passenger preferences deteriorates
Solution Approach 1:
The patent implements dynamic driving behavior by allowing the autonomous vehicle system to switch between multiple pre-defined driving styles (e.g., conservative, moderate, aggressive) based on passenger selection. The system dynamically adjusts acceleration, braking, and steering parameters according to the selected style, enabling adaptability without requiring complex real-time optimization algorithms.
Solution Approach 2:
The system changes key driving parameters such as maximum acceleration, minimum following distance, and steering responsiveness based on the selected driving style. By pre-configuring parameter sets for different driving styles, the system achieves adaptability to passenger preferences while maintaining manageable complexity through discrete parameter switching rather than continuous optimization.
2Adaptability or versatility
If autonomous vehicles allow passenger control over driving behavior, then adaptability to individual preferences is improved, but device complexity increases
Solution Approach 1:
The patent segments the driving behavior control into distinct, pre-defined driving styles (e.g., conservative, moderate, aggressive) rather than allowing continuous adjustment of all parameters. This segmentation simplifies the user interface to a selection mechanism while the system internally manages the complexity of coordinating multiple parameter changes across different driving functions.
Solution Approach 2:
The system implements a universal driving style selector that controls multiple vehicle functions simultaneously (acceleration, braking, steering, lane changing). This single control interface provides multi-functionality, allowing passengers to adjust overall driving behavior without needing to independently control each parameter, thereby reducing perceived complexity while maintaining adaptability.
3Adaptability or versatility
If autonomous vehicles implement multiple driving styles, then passenger satisfaction is improved, but control predictability may deteriorate
Solution Approach 1:
The system performs preliminary configuration of driving parameters by pre-defining complete driving style profiles before operation. Each driving style comes with a predetermined set of parameters (acceleration rates, braking forces, steering angles) that are consistently applied. This preliminary action ensures that when a passenger selects a driving style, the vehicle behavior is predictable and consistent with that style's characteristics.
Solution Approach 2:
The system incorporates feedback mechanisms where passenger responses to autonomous actions are collected and used to refine or adjust driving behavior. This feedback loop enhances predictability by learning from passenger reactions, allowing the system to anticipate preferred responses and maintain consistent behavior patterns aligned with passenger expectations over time.

AI summary
A system and method for autonomous vehicle driving behavior modification include: receiving passenger driving behavior preferences for setting a driving behavior of an autonomous vehicle; generating driving behaviors controls based on the passenger driving behavior preferences; setting an initial driving behavior of the autonomous vehicle using the driving behavior controls, wherein setting the initial driving behavior comprises providing the driving behavior controls to be implemented by the autonomous vehicle during one or more routes involving the passenger; aggregating vehicle behavior feedback relating to a driving behavior of the autonomous vehicle during the one or more routes; and modifying the driving behavior of the autonomous vehicle based on the vehicle behavior feedback.
