Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving vehicles face challenges in maintaining user safety and comfort by accurately determining the lateral position on the road, as they struggle to consider unexpected obstacles and user preferences during autonomous driving mode.
Innovation Solution
An autonomous driving vehicle system that allows users to adjust and teach the desired lateral position using a user interface, with processor circuitry calculating a dynamic offset value based on user input and environmental data to adapt the vehicle's position, combining user preferences with environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous driving vehicle uses a default lateral position for autonomous driving, then the vehicle can maintain stable autonomous driving control, but the user may feel unsafe or uncomfortable when the vehicle drives too close to the centre or sides of the road
Solution Approach 1:
The system introduces feedback by detecting user inputs (steering wheel corrections, button presses) and using these signals to adjust the lateral position offset. The processor monitors user corrections and automatically adapts the default lateral position to match user preferences, creating a closed-loop feedback system that improves user comfort while maintaining autonomous driving stability
Solution Approach 2:
The system enables self-service by automatically learning and adapting to user preferences without requiring manual configuration. The processor analyzes user steering corrections and autonomously adjusts the lateral position offset, allowing the vehicle to self-optimize its driving behavior based on individual user preferences for safety and comfort margins
2Reliability
If the autonomous driving vehicle continuously adjusts the lateral position to ensure safety, then the vehicle can respond to unexpected obstacles, but it becomes difficult to consider user preferences and how the driver feels about the current situation
Solution Approach 1:
The system segments the lateral position control into two independent components: a safety-critical default lateral position determined by the autonomous driving system for obstacle avoidance, and a user-preference-based offset determined by user inputs. This segmentation allows each component to optimize its function independently while combining to provide both safety and user comfort
Solution Approach 2:
The system implements dynamics by making the lateral position offset adaptive rather than fixed. The processor continuously monitors user inputs and dynamically adjusts the offset value based on detected steering corrections and button presses, allowing the system to adapt to changing user preferences while maintaining the stable default lateral position for safety
3Device complexity
If the autonomous driving vehicle uses pre-set default settings for lateral position control, then the system complexity remains low, but the system cannot adapt to different user preferences and driving situations over time
Solution Approach 1:
The system enables self-service by automatically learning and storing user preferences without requiring manual programming or complex configuration interfaces. The processor analyzes user steering corrections and button presses, automatically determines preferred lateral positions for different situations, and stores these as learned offsets, allowing the system to adapt to individual users while maintaining simple operation
Solution Approach 2:
The system applies parameter changes by modifying the lateral position offset parameter based on detected user inputs. The processor changes the offset value dynamically according to the number and direction of steering corrections and button presses, allowing the system to adapt to user preferences through simple parameter adjustment rather than complex system reconfiguration

AI summary
An autonomous vehicle includes processor circuitry to control a lateral position of the autonomous vehicle during autonomous driving at least based on a default lateral position and a user interface arranged to receive an input indicative of an off-set of the lateral position from a user of the autonomous driving vehicle, wherein the processor circuitry is arranged to receive, from the user interface, information regarding the off-set of the lateral position of the autonomous driving vehicle during driving in the lateral position, calculate a maximum right and a maximum left off-set of the lateral position, calculate a dynamic off-set value based on the received off-set and the maximum right and the maximum left off-set, adjust the lateral position based on the off-set information, and control the lateral position at least based on the dynamic off-set value and the default lateral position of the autonomous driving vehicle.
