Vehicle Imaging System Positioning Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges in maneuvering vehicles within space-limited areas, such as garages, due to difficulties in accurately judging distances between the vehicle and surrounding objects, which can lead to damage upon exiting or closing the garage door.
Innovation Solution
A vehicle equipped with image capture devices and a controller that captures and compares reference and current images to generate graphics on a user display, providing guidance on the vehicle's position relative to a set home position, preventing damage by offering real-time positioning assistance and warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a driver manually judges distances in a space-limited area, then the driver can operate the vehicle without additional systems, but the driver cannot accurately determine the vehicle's position relative to surrounding objects
Solution Approach 1:
The system creates a visual copy of the desired parking position by capturing a reference image when the vehicle is correctly positioned. This reference image is then overlaid on the user display during subsequent parking maneuvers, allowing the driver to compare the live camera view with the stored reference to accurately judge distance and position without complex mechanical measurement devices
Solution Approach 2:
The user display acts as an intermediary between the image capture device and the driver. It overlays the reference image on top of the live camera feed, creating a composite visual guide that mediates the driver's perception of distance and position. This intermediary presentation method translates complex spatial relationships into an intuitive visual comparison that enhances measurement precision without requiring direct complex measurement hardware
2Reliability
If the vehicle enters a parked state in a garage, then the vehicle can be stored safely, but damage may occur when exiting if the vehicle position is not accurately known
Solution Approach 1:
The system performs preliminary action by capturing and storing a reference image of the garage environment when the vehicle is in the correct parked position. This reference data is saved in advance for future use, allowing the driver to retrieve position information when exiting without having to manually remember or measure the parking location
Solution Approach 2:
The system provides feedback by continuously displaying the overlaid reference image during vehicle movement in and out of the garage. The driver receives real-time visual feedback showing the difference between current vehicle position and the stored reference position, enabling continuous adjustment to maintain safe positioning and prevent damage upon exit

AI summary
A vehicle includes at least one image capture device and a user display configured to display images receive from the at least one image capture device. The vehicle also includes a controller programmed to generate a user prompt to set a home vehicle position in response the vehicle entering a first parked state. The controller is also programmed to store at least one reference image indicative of an area in a vicinity of the vehicle corresponding to the home vehicle position. The controller is further programmed to collect a current image corresponding to a current vehicle position in response to a subsequent approach toward the vicinity, and compare the current image to the reference image. The controller is further programmed to generate a user display depicting the vicinity, the current vehicle position, and the home vehicle position.
