Selectable Autonomous Driving Modes for Personalized Vehicle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicle owners have diverse preferences for how their vehicles operate, ranging from sporty to fuel-efficient or comfortable, which existing systems fail to adapt dynamically to changing user tastes.
Innovation Solution
An autonomous vehicle system with selectable driving modes, including 'time to target', 'eco-friendly', 'chauffeur', 'sport', and 'racecar' modes, controlled by a user interface and autonomous mode controller, adjusting vehicle subsystems and user interface 'personality' to match the chosen mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the autonomous vehicle operates with a fixed driving mode, then the system complexity is reduced, but the adaptability to different user preferences deteriorates
Solution Approach 1:
The system dynamically switches between multiple driving modes (sport, economy, comfort, race) based on user selection. Each mode adjusts vehicle characteristics such as acceleration, deceleration, steering responsiveness, and suspension settings, allowing the vehicle to adapt to different user preferences without requiring permanent structural changes.
Solution Approach 2:
The autonomous mode controller changes operational parameters of various vehicle subsystems based on the selected driving mode. This includes adjusting powertrain output, brake force distribution, steering ratio, and suspension stiffness to match the characteristics of the chosen mode, thereby achieving adaptability through parameter variation rather than hardware complexity.
2Adaptability or versatility
If the autonomous vehicle adjusts multiple subsystems for different driving modes, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The autonomous mode controller serves as a universal control unit that manages multiple vehicle subsystems simultaneously. It coordinates adjustments across the powertrain, braking, steering, and suspension systems through a single control interface, reducing the need for separate control mechanisms for each subsystem and managing complexity through functional integration.
3Ease of operation
If the user interface personality is adjusted to match driving modes, then the user experience is enhanced, but the device complexity increases
Solution Approach 1:
The user interface device combines multiple functions into a single system: it displays driving mode selections, provides feedback about vehicle status, and adjusts its communication style and visual characteristics to match the selected driving mode. This merging of display, control, and communication functions into one integrated interface enhances user experience without proportionally increasing complexity.

AI summary
A vehicle system includes a user interface device and an autonomous mode controller. The user interface device receives a user input representing a driving mode selection. The autonomous mode controller commands one or more vehicle subsystems to operate in accordance with characteristics associated with the driving mode selection. Examples of characteristics can include how aggressively the vehicle accelerates or decelerates, a minimum distance from the vehicle to a front vehicle, or how frequently the vehicle changes lanes, among others.
