Lane Guidance Display for Early Adjacent-Lane Change Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies in driving assistance systems often fail to provide timely and accurate guidance for lane changes, leading to user discomfort and reduced convenience, particularly when the destination lane is not immediately recognizable.
Innovation Solution
A control device and method that superimposes an image of the vehicle's movement onto an adjacent lane on the display, even when the lane is not yet recognized by the system, using road information to anticipate and display the lane ahead, and optionally performs automatic lane changes with synchronized guidance imagery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display waits for the recognizer to detect the destination lane before displaying lane change guidance, then the display accuracy is improved, but the response timing is delayed and user convenience deteriorates
Solution Approach 1:
The system performs preliminary actions by displaying the movement path image before the recognizer actually detects the destination lane. It uses predicted position information and map data to anticipate where the lane will be, allowing guidance to appear in advance rather than waiting for confirmation detection
Solution Approach 2:
The patent introduces an intermediary approach by using a movement path image that is superimposed on the camera image. This movement path serves as a visual mediator that bridges the gap between the vehicle's intended movement and the recognizer's delayed detection, providing intuitive guidance without requiring immediate lane recognition
2Ease of operation
If the display shows the movement path image superimposed on the camera image, then the guidance intuitiveness is improved, but the display complexity increases
Solution Approach 1:
The patent merges the movement path image with the camera image into a single composite display. By superimposing the predicted movement path over the real-time camera view, it combines predictive information with actual visual feedback, creating an intuitive guidance display that shows where the vehicle will move relative to the current scene
Solution Approach 2:
The system adds a temporal dimension to the display by showing not just the current lane position but also the future movement path. This dimensional addition allows the display to convey both present state and intended action simultaneously, improving intuitiveness without requiring separate displays

AI summary
A control device causes a display to display a lane; causes the display to display, in a case in which a target route is on a side of a lane adjacent to a first lane, an image in which an image of an object of movement display showing movement of the moving body to the lane side is superimposed on an image of an object of the adjacent lane; and causes the display to display, in a case in which the adjacent lane is a second lane connected to the first lane and widening ahead of a location, an image of an object of the second lane even in a case in which the second lane has not been recognized when the display is caused to display an image of an object of the movement display.
