Vehicle Head-Up Display Virtual Preceding Vehicle Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation and head-up display systems do not effectively guide drivers by providing route information and ensuring safety distances, nor do they assist in lane changes or emergency situations.
Innovation Solution
An assistance apparatus for vehicles that displays a virtual preceding vehicle, controlled by a processor based on route and sensing information, offering various modes to guide the driver and ensure safety distances, lane changes, and emergency handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional navigation devices display route information on a monitor or separate device, then the information can be displayed, but the driver cannot easily recognize it while driving, compromising safety
Solution Approach 1:
The patent projects navigation information from a 2D monitor screen onto the 3D windshield surface, transforming the display dimension. This allows the driver to view route information in the line of sight without diverting attention from the road, simultaneously improving safety and information accessibility
Solution Approach 2:
The patent introduces a windshield as an intermediary medium between the navigation system and the driver. By projecting information onto the windshield, it serves as a mediator that delivers route guidance directly in the driver's visual field without requiring direct interaction with a separate display device
2Ease of operation
If head up displays are used to display virtual preceding vehicle or speed information, then the driver can easily recognize the information, but the system cannot provide comprehensive route guidance and lane change assistance
Solution Approach 1:
The patent transforms the head-up display from a single-function speed indicator into a multi-functional guidance system. It simultaneously displays speed information, virtual preceding vehicle, route guidance arrows, lane change indicators, and traffic signals, making one system perform multiple driving assistance functions
Solution Approach 2:
The patent merges multiple separate information streams (navigation route, traffic information, vehicle speed, preceding vehicle data) into a single integrated head-up display interface. This combines previously separate functions into one unified system that provides comprehensive driving guidance
3Adaptability or versatility
If the system displays comprehensive route information and traffic data, then the guidance capability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple information processing functions (route calculation, traffic data processing, vehicle sensor integration, display control) into a single integrated system that projects all information through one head-up display interface, reducing overall system complexity while maintaining comprehensive functionality
Data Source
AI summary
The present invention relates to an assistance apparatus for driving of a vehicle including a display unit displaying the virtual preceding vehicle corresponding to one virtual preceding mode, which is selected by a user, of a plurality of virtual preceding modes, an interface unit receiving route information including destination information that is set by a driver and sensing information detected by a sensing unit, and a processor controlling the virtual preceding vehicle on the basis of the route information and the sensing information.
