Vehicle Stop Position Projection for Autonomous Parking Exit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in accurately recognizing the stop position of a vehicle when leaving a parking lot during autonomous driving, as the displayed stop position may not align with the actual stop position.
Innovation Solution
A vehicle control system that includes a route generating unit to create a parking lot leaving route based on sensor data, a communication control unit to transmit this route to an external device, and a projection control unit to project light onto the road surface indicating 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 of the vehicle
Solution Approach 1:
The patent introduces a light projection as an intermediary visual marker between the information processing device display and the actual vehicle stop position. The light is projected onto the road surface at the precise stop position, serving as a physical mediator that bridges the gap between digital information display and physical world recognition, enabling users to accurately identify where the vehicle will stop.
Solution Approach 2:
The patent transitions the stop position information from a two-dimensional display on the information processing device screen to a three-dimensional visual marker projected directly onto the road surface. This dimensional change allows users to perceive the stop position in the same spatial context as the vehicle's actual movement, significantly 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 system projects light at the predetermined stop position before the vehicle arrives, providing visual feedback to the user about where the autonomous vehicle will stop. This allows the user to verify and understand the autonomous system's intended action, maintaining awareness during automated operation.
Solution Approach 2:
The system performs preliminary action by projecting the light marker at the stop position before the vehicle actually stops. This advance visual indication allows users to prepare and confirm the stop location in advance, improving situation awareness during autonomous driving operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Accurately notifies users and others of the vehicle's stop position by projecting light onto the road surface, enhancing safety during autonomous parking lot exits.
Implementation Method 1
a projection control unit that projects light emitted from a light source onto a position on a road surface corresponding to the stop position
Data Source
AI summary
A vehicle control device includes a route generating unit, a communication control unit, and a projection control unit. The route generating unit generates a parking lot leaving route of a vehicle based on sensing results of a sensor group mounted on the vehicle. The communication control unit transmits the parking lot leaving route to an information processing device and receives a stop position where the vehicle stops from the information processing device. The projection control unit projects light emitted from a light source at a position on a road surface corresponding to the stop position.
