Augmented Reality Virtual Vehicle for Cruise Control Detection Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle cruise control systems temporarily release the preceding vehicle following cruise function when the road changes from a straight road to a slope or curved road, causing transient disconnection and driver anxiety due to temporary loss of preceding vehicle detection.
Innovation Solution
A vehicle cruise control method and apparatus that uses augmented reality to display a virtual preceding vehicle when the real vehicle is not detected on a slope or curved road, with a controller determining road type and displaying a virtual vehicle in the driver's information display region, switching modes based on vehicle re-detection and set time, maintaining driving stability and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cruise control releases the preceding vehicle following cruise function when the preceding vehicle is temporarily not detected on slope or curved roads, then the system avoids false detection errors, but the driver experiences transient disconnection and anxiety
Solution Approach 1:
The system creates a virtual copy of the preceding vehicle and displays it in the information display region when the real vehicle is temporarily undetected. This virtual vehicle copy maintains the following cruise function visually continuous, preventing driver anxiety while the system continues to search for the actual vehicle.
Solution Approach 2:
The virtual preceding vehicle acts as an intermediary between the driver and the actual preceding vehicle. When detection is temporarily lost, the virtual vehicle mediates the connection, maintaining driver confidence and system continuity until the real vehicle is detected again.
2Ease of operation
If augmented reality virtual display is used to maintain preceding vehicle visibility, then driver confidence is maintained, but system complexity increases
Solution Approach 1:
The controller is designed to perform multiple functions: normal vehicle detection, road type identification (slope/curved), and virtual vehicle display. By integrating these functions into the existing controller, the system avoids adding separate dedicated hardware, thereby limiting the increase in complexity.
Solution Approach 2:
Instead of creating complex new display hardware, the system uses software-based virtual vehicle copying and displays it through the existing information display region using augmented reality techniques, maintaining simplicity while achieving the confidence-building effect.
3Reliability
If the system continuously searches for preceding vehicle on slope or curved roads, then detection reliability improves, but false detections may occur
Solution Approach 1:
The system dynamically adjusts its behavior based on road conditions. When a slope or curved road is detected, the system enters a special mode where it continues the following cruise function using virtual vehicle display instead of normally releasing it, allowing adaptive response to challenging detection environments.
Solution Approach 2:
The system uses its own road recognition capability to identify slope or curved conditions and automatically activates the appropriate detection and display mode. This self-service mechanism allows the system to handle difficult detection scenarios without external intervention while maintaining reliability.

AI summary
A vehicle cruise control apparatus of a vehicle includes a display and a controller. The display displays virtual information by projecting the virtual information on an information display region in front of a driver of the vehicle through augmented reality. The controller determines whether the front road is a slope road or a curved road based on road information while controlling driving of the vehicle according to an inter-vehicle distance and a driving speed of the preceding vehicle, determines whether the preceding vehicle exists in an information display region in front of a driver when it is determined that the front road is the slope road or the curved road, and controls the display to display a virtual preceding vehicle in the information display region through augmented reality when it is determined that the preceding vehicle does not exist.
