Connected Vehicle Parking Awareness System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In parking lots, the limited space and visibility create challenges for drivers to avoid collisions with other vehicles or pedestrians, and existing solutions such as mirrors and camera installations are either limited in effectiveness or costly to implement.
Innovation Solution
A vehicle system that uses sensors to identify subjects in a conflict zone, determines the trajectories of vehicles and subjects, and calculates a suggested trajectory for the vehicle to avoid potential collisions, which is then transmitted to the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If mirrors are installed to improve driver visibility, then driver awareness is improved, but the solution is limited in effectiveness due to placement constraints and cannot provide comprehensive coverage
Solution Approach 1:
The patent transitions from two-dimensional mirror surfaces to three-dimensional omnidirectional camera coverage. The camera system captures images from multiple angles (front, rear, left, right) and transmits them to the driver's display, providing全方位 visibility without the placement constraints of mirrors.
Solution Approach 2:
Instead of using physical mirrors to reflect light, the system creates optical copies of the environment through cameras and displays images on electronic screens. This allows the driver to see what would otherwise be blind spots without requiring physical structures in specific locations.
2Loss of information
If cameras are installed in the parking lot to transmit information to vehicles, then driver awareness is improved, but the implementation is time-consuming and expensive for the parking lot operator
Solution Approach 1:
The system leverages cameras already equipped in vehicles (self-service) rather than requiring the parking lot operator to install a dedicated camera system. Each vehicle uses its own onboard sensors to capture and transmit environmental information, eliminating the need for expensive infrastructure investment.
Solution Approach 2:
The patent makes vehicles multi-functional by having them serve both as transportation and as mobile sensing nodes. The vehicle's existing cameras perform dual purposes: capturing images for the driver's entertainment and simultaneously providing safety awareness information to other drivers in the parking lot.
3Reliability
If vehicles drive slower and drivers remain more attentive, then collision risk is reduced, but the limited space and visibility in parking lots constrain the effectiveness of these actions
Solution Approach 1:
The system continuously captures images from multiple vehicles, processes them to identify conflict zones, and provides real-time feedback to drivers through displays. This closed-loop feedback enables drivers to respond appropriately to potential hazards without manually monitoring all surrounding areas.
Solution Approach 2:
The system introduces an intermediary processing layer between the physical environment and the driver's perception. Image processing algorithms analyze the raw camera data, identify potential conflicts, and present simplified warnings to the driver, reducing the cognitive load and improving reaction time.

AI summary
In accordance with one embodiment of the present disclosure, a vehicle system includes a controller. The controller may be programmed to perform operations including identifying a subject in a conflict zone in a parking area by a sensor, determining a trajectory of a vehicle and a trajectory of the subject, determining a suggested trajectory for the vehicle based on a comparison of the trajectory of the vehicle and the trajectory of the subject, and transmitting the suggested trajectory to the vehicle.
