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

VSEngineering 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

Engineering Contradiction:
Improvedriver acceptanceVSAvoidparking space length
Core Design Contradiction:
ReliabilityVSLength of stationary object

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.

Inventive Principle:

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.
