Road Surface Stop Position Projection for Autonomous Parking Exit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During autonomous driving, users face challenges in accurately recognizing the stop position of a vehicle leaving a parking lot, as the information processing device may not accurately display the actual stop position set by the user.
Innovation Solution
A vehicle control device that includes a route generating unit to create a parking lot leaving route based on sensor data, a communication control unit to transmit and receive stop position information, and a projection control unit to project light onto the road surface corresponding to the stop position, ensuring accurate notification of the stop position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a stop position is displayed on an information processing device, then the user can set a stop position for the vehicle, but the user cannot accurately recognize the actual stop position
Solution Approach 1:
The patent introduces a light projection as an intermediary element between the information processing device and the road surface. The light projects the stop position information onto the road, creating a visual marker that the user can directly see at the actual location, thereby accurately recognizing the stop position without relying solely on the information processing device display
Solution Approach 2:
The patent transitions the stop position information from a two-dimensional display on the information processing device to a three-dimensional visual projection on the road surface. This dimensional change allows the user to perceive the exact stop position in the physical space where the vehicle will stop, improving recognition accuracy
2Extent of automation
If autonomous driving control is implemented, then the vehicle can leave the parking lot automatically, but the user cannot accurately recognize where the vehicle will stop
Solution Approach 1:
The patent implements a feedback mechanism where the stop position information is projected onto the road surface at the actual stop location. This provides visual feedback to the user about where the autonomous vehicle will stop, allowing the user to verify and recognize the stop position accurately before the vehicle arrives
