Lane-Change Support Display for Accurate Relative Vehicle Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information providing devices fail to accurately display the relative positions of a vehicle and peripheral vehicles, making it difficult for drivers to assess the safety of lane changes.
Innovation Solution
A driving support device that includes a vehicle detecting unit, an image generating unit, and a display unit, which uses symbols to show the relative dispositions of vehicles in real time, providing accurate positional information to the driver through a dedicated display screen, such as a rear-view mirror or side mirror, and issuing warnings for potential collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a three-by-three matrix of rectangles is used to display vehicle positions, then the device complexity is reduced, but the measurement precision of relative vehicle positions deteriorates
Solution Approach 1:
The patent transitions from a two-dimensional matrix representation to a three-dimensional spatial representation by displaying vehicle images at actual relative positions in depth. The display unit shows multiple vehicle images positioned according to their real spatial relationships, allowing drivers to perceive distance and position more accurately while maintaining simple display hardware.
2Device complexity
If only rectangular positions are shown in the matrix display, then the device complexity is reduced, but the loss of information about actual vehicle positions increases
Solution Approach 1:
The patent creates visual copies of the actual driving scene by displaying vehicle images that replicate real-world positions and relationships. Instead of abstract rectangles, the system generates image copies positioned in space to mirror the actual spatial arrangement of vehicles, preserving complete position information while keeping the display system simple.
3Device complexity
If intuitive assessment is required from the driver, then the device complexity is reduced, but the reliability of lane change safety assessment deteriorates
Solution Approach 1:
The patent implements feedback by providing the driver with accurate real-time spatial information about surrounding vehicles through the display unit. The system continuously updates the positions of vehicle images based on detected vehicle locations, giving the driver reliable feedback about the safety of lane changes without requiring complex intuitive assessment.

AI summary
A driving support device wherein an own vehicle and a peripheral vehicle are symbolized, and relative dispositions are displayed in real time in a display unit visible to the driver, is obtained to facilitate a lane change by a driver. The driving support device includes a vehicle detecting unit, which detects peripheral vehicles positioned in a periphery of a vehicle, and an image generating unit, which generates an image representing positions of the vehicle and the peripheral vehicles from vehicle information obtained by the vehicle detecting unit. The image generating unit generates a driving support image including vehicle information representing relative dispositions of the vehicle and the peripheral vehicles using symbols indicating the vehicle and the peripheral vehicles. The image generating unit includes an image stacking unit, which generates original data of the driving support image, and an image control unit, which cuts a necessary portion from the original data.
