Virtual Lane Display for Platooning Visual Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In platooning, large preceding vehicles obstruct the visual field of drivers in following vehicles, increasing the burden of transverse steering due to short inter-vehicle distances, which can lead to safety issues and difficulties in maintaining lane control.
Innovation Solution
An apparatus and method for displaying a virtual lane by converting lane information from a preceding vehicle into a viewpoint-based image for the following vehicle, using a processor to generate and display this information on a windscreen, including augmented reality, to assist drivers in steering control and provide lane departure warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the inter-vehicle distance is reduced to enhance fuel efficiency, then fuel efficiency is improved, but the visual field of the driver is obstructed by the preceding vehicle
Solution Approach 1:
The patent introduces an intermediary system consisting of sensors, processors, and display devices that mediate between the preceding vehicle's lane information and the following vehicle's driver. This intermediary system captures lane information from the preceding vehicle, processes and converts it to the following vehicle's viewpoint, and displays it on the windshield, thereby resolving the visual obstruction problem while maintaining short inter-vehicle distances for fuel efficiency
Solution Approach 2:
The patent creates a virtual copy of the lane information from the preceding vehicle's perspective and transforms it into the following vehicle's perspective. By copying the lane detection data and re-rendering it from the following vehicle's viewpoint, the system provides the driver with visual information that would otherwise be blocked by the preceding vehicle, allowing safe following at reduced distances
2Loss of energy
If the inter-vehicle distance is reduced to enhance fuel efficiency, then fuel efficiency is improved, but the driver burden for transverse steering increases
Solution Approach 1:
The system acts as an intermediary that provides the driver with enhanced visual information about the lane and preceding vehicle position. By displaying virtual lane markings and position indicators on the windshield, the system reduces the cognitive and operational burden on the driver for transverse steering tasks, even when maintaining short inter-vehicle distances
Solution Approach 2:
The system provides continuous visual feedback to the driver about the vehicle's position relative to the lane and preceding vehicle. By displaying real-time lane information and position indicators, the system enables the driver to make smaller, more precise steering adjustments, reducing overall driver burden while maintaining fuel-efficient short following distances
3Object-affected harmful factors
If lane information from the preceding vehicle is converted to the following vehicle's viewpoint, then the driver can see the virtual lane despite obstruction, but the device complexity increases
Solution Approach 1:
The patent implements a multi-functional system where the same hardware components (sensors, processors, display devices) serve multiple functions: detecting lane markings, tracking the preceding vehicle, converting coordinate systems, and displaying virtual lane information. This universal approach reduces overall device complexity compared to having separate dedicated systems for each function
Solution Approach 2:
The system merges the lane detection, viewpoint conversion, and display functions into an integrated architecture. By combining these functions into a unified system with shared processing resources and coordinated operation, the patent reduces the complexity that would arise from having separate independent systems for each function
