Automated Valet Parking Sensor Contamination Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Raindrops or dirt on the in-vehicle sensor can prevent the detection of landmarks or obstacles in a parking lot, leading to interruptions or discontinuation of automated valet parking services, especially in rainy weather.
Innovation Solution
The vehicle is equipped with a detection unit that identifies dirt or raindrops on the in-vehicle sensor before automated valet parking begins, and an informing unit that outputs information to users or parking lot managers to prompt them to clean the sensor, ensuring its functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated valet parking is executed based on in-vehicle sensor detection, then parking service automation is improved, but service interruption occurs when raindrops or dirt attach to the sensor
Solution Approach 1:
The detection unit performs preliminary detection of raindrops or dirt on the in-vehicle sensor before the automated valet parking is executed. This advance detection allows the system to identify sensor contamination issues prior to starting the parking operation, preventing service interruption by prompting users to clean the sensor in advance.
Solution Approach 2:
The informing unit provides feedback to users when the detection unit identifies raindrops or dirt on the sensor. This feedback mechanism notifies users of the sensor contamination status and prompts them to clean the sensor, ensuring the sensor remains functional for reliable automated parking operation.
2Duration of action of moving object
If the in-vehicle sensor is used in rainy weather, then automated parking can continue, but detection accuracy deteriorates due to raindrops on the sensor
Solution Approach 1:
The detection unit performs preliminary detection of raindrops on the sensor before automated parking starts. By detecting contamination in advance, the system can prompt users to clean the sensor, ensuring detection accuracy is maintained during the parking operation even in rainy weather conditions.
Solution Approach 2:
The system takes preliminary anti-action by detecting and alerting users to raindrop contamination before it affects detection accuracy. The informing unit prompts users to remove raindrops or dirt from the sensor, preventing the harmful effect of reduced detection precision before it occurs during the parking operation.

AI summary
A vehicle includes: an in-vehicle sensor that detects an environment around the vehicle; an autonomous driving unit that executes automated valet parking based on the detection result from the in-vehicle sensor; a detection unit that detects dirt or a raindrop attached to the in-vehicle sensor before the automated valet parking is started by the autonomous driving unit; and an informing unit that outputs information that suggests removing the dirt or the raindrop on the in-vehicle sensor in response to the detection unit detecting the dirt or the raindrop attached to the in-vehicle sensor.
