Automated Driving Maneuver Adaptation Based on Driver Characterization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated driving maneuvers, such as parking, often require larger parking spaces due to safety distance constraints, which can be inefficient and may interrupt if the driver is not experienced, leading to a compromise between technical feasibility and driver acceptance.
Innovation Solution
The method adapts automated driving maneuvers to individual drivers by characterizing them based on past experiences, including the number and type of maneuvers, time profile, and environmental conditions, allowing for reduced safety distances and optimized route planning, enabling the use of shorter parking spaces and faster maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control device maintains sufficient safety distances during automated driving maneuvers, then the reliability and driver acceptance are improved, but the parking space length required increases
Solution Approach 1:
The control device dynamically adapts the safety distance based on the driver's experience level. For experienced drivers, smaller safety distances are used to optimize parking space utilization, while for less experienced drivers, larger safety distances are maintained to ensure acceptance and avoid maneuver interruption. This dynamic parameter adjustment resolves the contradiction between reliability and parking space length.
Solution Approach 2:
The system changes the safety distance parameter according to the driver's characterization. By evaluating the driver's experience through past maneuver data and manually entered values, the control device adjusts the safety distance parameter to match the driver's preferences and expectations, thereby maintaining reliability while minimizing parking space requirements.
2Length of stationary object
If the control device uses smaller safety distances to optimize parking space usage, then the parking space length is reduced, but the driver acceptance decreases and maneuvers may be interrupted
Solution Approach 1:
The control device dynamically adapts the safety distance based on the driver's experience level. For experienced drivers, smaller safety distances are used to optimize parking space utilization, while for less experienced drivers, larger safety distances are maintained to ensure acceptance and avoid maneuver interruption. This dynamic parameter adjustment resolves the contradiction between reliability and parking space length.
Solution Approach 2:
The system changes the safety distance parameter according to the driver's characterization. By evaluating the driver's experience through past maneuver data and manually entered values, the control device adjusts the safety distance parameter to match the driver's preferences and expectations, thereby maintaining reliability while minimizing parking space requirements.
3Productivity
If the automated driving maneuver is performed with minimum safety distances, then the parking space efficiency is improved, but the maneuver may break off due to driver concern about safety
Solution Approach 1:
The control device performs preliminary characterization of the driver before executing the automated driving maneuver. By evaluating the driver's experience level in advance through past maneuver data and manual input, the system determines the appropriate safety distance to use, ensuring both efficiency and maneuver completion while avoiding driver-induced interruptions.
Solution Approach 2:
The control device dynamically adapts the safety distance based on the driver's experience level. For experienced drivers, smaller safety distances are used to optimize parking space utilization, while for less experienced drivers, larger safety distances are maintained to ensure acceptance and avoid maneuver interruption. This dynamic parameter adjustment resolves the contradiction between reliability and parking space length.
