Vehicle Guide Lamp for Helical Parking Lot Collision Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles, especially in helical access roads of parking lots, face frequent collisions due to driver inexperience, narrow paths, and improper placement of parking tollgates, with conventional systems only passively warning drivers, leading to operational errors and accidents.
Innovation Solution
A vehicle equipped with a global navigation satellite system (GNSS) receiver, guide lamps, cameras, and radar, which identify entry into a parking lot or curved road and display light lines representing the path and vehicle area, and control steering or braking to prevent collisions based on time-to-collision calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional passive warning system is used, then the driver is informed of collision risk, but the driver may make operational errors leading to accidents
Solution Approach 1:
The patent introduces a guide lamp as an intermediary visual aid that projects light lines on the road to show the vehicle's travel path and occupied area. This intermediary system bridges the gap between the driver and the complex collision risk information, providing intuitive visual guidance that reduces driver operational errors while maintaining collision prevention effectiveness
Solution Approach 2:
The system performs preliminary action by projecting the guide lamp light lines in advance to show the predicted travel path and occupied area before the vehicle actually moves. This allows the driver to anticipate the vehicle's movement and potential collision risks ahead of time, preventing operational errors before they occur
2Area of moving object
If the vehicle width increases, then the passenger comfort and space improve, but the collision risk increases on narrow helical access roads
Solution Approach 1:
The guide lamp projects the occupied area in advance on the road, allowing drivers of wider vehicles to visualize the space the vehicle will occupy before entering narrow helical access roads. This preliminary visual information enables drivers to assess whether the vehicle can safely navigate the narrow path, preventing collisions while allowing wider vehicles to be operated
Solution Approach 2:
The guide lamp acts as an intermediary that provides visual feedback about the relationship between the wider vehicle and the narrow road geometry. By projecting light lines that show the occupied area, the system mediates between the driver's intent to use a wider vehicle for comfort and the physical constraint of narrow roads, enabling informed driving decisions
3Productivity
If the helical access road is made narrower to increase parking capacity, then more vehicles can be parked, but collision frequency increases
Solution Approach 1:
The guide lamp serves as an intermediary system that compensates for the reduced safety margin in narrower roads. By projecting visual guidance showing the precise travel path and occupied area, the system enables narrow roads to be used safely, maintaining high parking capacity while reducing collision frequency through improved driver awareness and control

AI summary
A vehicle is provided. The vehicle includes: a global navigation satellite system (GNSS) receiver configured to receive a signal from a GNSS; a guide lamp installed on a front portion of the vehicle; and a controller electrically connected to the GNSS receiver and the guide lamp, wherein the controller is configured to: identify an entry of the vehicle into a parking lot based on a GNSS signal acquired by the GNSS receiver; and control the guide lamp to display a light line representing a path to be travelled by the vehicle and an area to be occupied by the vehicle on a road ahead of the vehicle based on the entry of the vehicle into the parking lot.
