Autonomous Vehicle Ride Control via Dynamic Motion Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack the ability to respond in real-time to occupant preferences, failing to tailor ride characteristics dynamically and comfortably, unlike manually controlled vehicles.
Innovation Solution
A system and method for autonomously controlling vehicles by obtaining ride preference information, determining a motion plan based on this information, and operating actuators to influence vehicle movement, incorporating sensors, actuators, and a controller that processes sensor data and ride preferences to adjust speed, acceleration, and steering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous vehicles operate in fully autonomous mode, then automation level is improved, but ability to respond to occupant preferences in real-time deteriorates
Solution Approach 1:
The system implements feedback by continuously monitoring occupant preferences through sensors (seats, climate control, entertainment) and using this information to dynamically adjust vehicle operation parameters such as acceleration, braking, and route selection, enabling the autonomous vehicle to adapt to individual occupant needs without human intervention
Solution Approach 2:
The autonomous vehicle performs self-service by automatically adjusting its operation characteristics based on detected occupant preferences, eliminating the need for manual input while maintaining personalized service through autonomous decision-making about acceleration rates, braking behavior, and climate control settings
2Adaptability or versatility
If traditional manually-controlled vehicles are used, then ability to tailor ride characteristics dynamically is improved, but automation level deteriorates
Solution Approach 1:
The system replaces manual mechanical control with automated electronic control systems that detect occupant preferences through sensors and automatically adjust vehicle operation parameters, substituting the mechanical interaction of manual driving with intelligent automated decision-making while preserving the ability to tailor ride characteristics
3Ease of operation
If autonomous vehicles lack real-time response to occupant preferences, then automation operation is simplified, but ride comfort and satisfaction deteriorate
Solution Approach 1:
The system implements dynamics by continuously adapting vehicle operation characteristics in real-time based on changing occupant preferences and environmental conditions, adjusting acceleration, braking, and routing decisions dynamically to maintain both operational simplicity and high ride comfort throughout the journey

AI summary
Systems and method are provided for controlling a vehicle. In one embodiment, a method includes: obtaining ride preference information associated with a user, identifying a current vehicle pose, determining a motion plan for the vehicle along a route based at least in part on the ride preference information, the current vehicle pose, and vehicle kinematic and dynamic constraints associated with the route, and operating one or more actuators onboard the vehicle in accordance with the motion plan. The user-specific ride preference information influences a rate of vehicle movement resulting from the motion plan.
