Augmented Reality HUD Virtual Preceding Vehicle Route Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems using augmented reality head-up displays (HUD) struggle to provide clear and accurate road guidance, leading to difficulties for drivers in following a preceding vehicle to the same destination, as they often mistake the route information displayed as lines or arrows, which can compromise driving safety.
Innovation Solution
An apparatus and method that create a virtual preceding vehicle on an augmented reality HUD, guiding it towards the driver's vehicle destination, using a route creator, controller, and HUD to display the virtual vehicle at a reference distance, adjusting based on vehicle speed and providing direction information through flickering turn signals and animations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If route information is displayed as lines or arrows on the front glass, then the display is simple and easy to implement, but the driver cannot correctly visualize the route and often mistakes the guidance
Solution Approach 1:
The patent creates a virtual preceding vehicle that copies the appearance and behavior of a real vehicle. This virtual vehicle is displayed on the HUD and follows the calculated route, providing intuitive route visualization while maintaining the simplicity of the display system. The virtual vehicle's movement and positioning directly represent the guidance path without requiring complex graphical representations.
2Reliability
If a virtual preceding vehicle is displayed on the augmented reality HUD, then route visibility and driving safety are improved, but the device complexity increases
Solution Approach 1:
The virtual preceding vehicle serves multiple functions simultaneously: it provides route guidance, indicates turning directions, shows estimated arrival time, and displays distance to destination. By consolidating these multiple information delivery functions into a single visual element, the system achieves improved driving safety without proportionally increasing device complexity.
Solution Approach 2:
The virtual preceding vehicle acts as an intermediary between the navigation system's calculated route and the driver's understanding of the guidance. This intermediary element translates complex navigation data into an intuitive visual representation that drivers can easily interpret, improving safety while maintaining user-friendly interaction.
3Ease of manufacture
If the virtual preceding vehicle is displayed at a fixed position, then the display is simple, but the driver cannot recognize the inclination and driving career of the preceding vehicle
Solution Approach 1:
The virtual preceding vehicle dynamically adjusts its position, orientation, and movement based on the calculated route and current vehicle state. The virtual vehicle follows the road curvature, changes direction at turns, and maintains appropriate spacing, providing drivers with information about inclination and driving career while remaining computationally efficient.

AI summary
An apparatus and method of providing road guidance based on an augmented reality head-up display (HUD) are provided. The method includes creating, by a controller, a route toward a destination and operating the augmented reality HUD to display a virtual preceding vehicle driven along the route to show that the virtual preceding vehicle is driven in front of a traveling vehicle by a reference distance.
