Automatic Parking Warning Restriction on Sharp Steering Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assist devices do not adequately address the issue of unsafe driver behavior during automatic parking control, leading to potential suspension of the system due to inappropriate warning information when the driver grasps the steering wheel significantly or on sharp curves, hindering the parking process.
Innovation Solution
A parking assist device that includes a control system to detect unsafe driver states, such as not grasping the steering wheel, and selectively restricts warning information during specific sections of the parking process, such as significant steering wheel rotation or sharp curves, while allowing automatic parking to continue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If warning information is indicated when the driver is in an unsafe state during automatic parking control, then driver safety is improved, but the automatic parking control may be suspended due to increased steering torque
Solution Approach 1:
The system dynamically adjusts the warning indication strategy based on the vehicle's operational state. When the host vehicle is traveling in a specific section during automatic parking control, the warning restriction control prevents warning information from being indicated, even if the driver is in an unsafe state. This dynamic adaptation resolves the contradiction by temporarily prioritizing parking control continuity over safety warnings in critical sections, while maintaining safety monitoring without indication.
2Loss of information
If warning information is indicated to alert the driver of unsafe behavior, then driver awareness is improved, but the timing may be inappropriate during significant steering wheel rotation
Solution Approach 1:
The system implements warning restriction control that proactively prevents warning information from being indicated when the host vehicle is traveling in a specific section, before the actual unsafe state occurs. By predicting that significant steering wheel rotation may occur in certain sections, the system preemptively restricts warnings, avoiding the timing issue where warnings would be inappropriate or confusing to the driver.

AI summary
A parking assist device includes: a control device configured to control a host vehicle; and an informing device. The control device is configured to execute automatic parking control. The control device is configured to execute warning control in which the informing device is controlled such that the informing device indicates predetermined warning information when the control device detects that a driver of the host vehicle is in an unsafe state during execution of the automatic parking control. The control device is configured to execute warning restriction control in which indication of the warning information by the informing device is restricted when the host vehicle is traveling in a predetermined specific section during the execution of the automatic parking control.
