Vehicle Headlamp and HUD Integration for Hazard Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems, such as intelligent headlamp systems, primarily rely on light emission control to alert drivers to precarious objects, which may not be sufficient for recognizing oncoming vehicles or pedestrians, especially in areas not illuminated by the headlamp, potentially leading to difficulty in noticing these objects.
Innovation Solution
A control apparatus that integrates a headlamp and a head-up display (HUD) to control light emission based on object position and type, while simultaneously displaying alert images on the HUD to indicate the position of precarious objects, ensuring the alert is superimposed or adjacent to the object's actual position in the driver's view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the headlamp switches from high beam to low beam to avoid illuminating the oncoming vehicle, then the oncoming vehicle is not obstructed, but the driver's ability to notice the oncoming vehicle deteriorates
Solution Approach 1:
The patent introduces a head-up display (HUD) as an intermediary device that receives information from the detection apparatus about precarious objects and presents it to the driver in a visual format. The HUD acts as a mediator between the detection system and the driver, allowing the driver to be aware of oncoming vehicles without directly viewing them through the headlamp beam pattern.
Solution Approach 2:
The patent replaces the mechanical/optical approach of using headlamp beam patterns to alert drivers with an electronic information presentation system. Instead of relying on the physical light beam to convey danger information, the system uses electronic detection and visual display on the HUD to substitute the traditional mechanical warning method.
2Device complexity
If only headlamp light emission control is used to alert drivers to precarious objects, then the system remains simple, but the driver's recognition of precarious objects especially in unilluminated areas deteriorates
Solution Approach 1:
The patent merges the headlamp control system with the head-up display system into an integrated precarious object warning system. The detection apparatus, light emission controller, and display controller work together as a unified system, combining the functions of illumination control and information presentation to achieve better object recognition while maintaining reasonable system complexity.
Solution Approach 2:
The head-up display serves multiple functions: it displays navigation information, vehicle status, and now serves as an additional warning mechanism for precarious objects. By making the HUD multi-functional, the system enhances driver awareness of precarious objects without requiring a completely separate warning system, thus balancing complexity improvement with functional enhancement.
3Loss of information
If the headlamp illuminates precarious objects to alert the driver, then the driver can recognize the objects, but the light may cause harmful effects such as glare or distraction
Solution Approach 1:
The patent creates a visual copy or representation of the precarious object information on the head-up display rather than directly illuminating the object with the headlamp. The display controller generates a visual indicator that replicates the essential information about the precarious object's position and nature, allowing the driver to perceive the danger without the harmful effects of direct headlamp illumination such as glare or excessive distraction.

AI summary
Control apparatus that controls headlamp of a vehicle and HUD of the vehicle includes acquirer that obtains information about an object situated ahead of the vehicle from monitoring apparatus monitoring an area ahead of the vehicle, light emission controller that controls the light emission form of headlamp based on a position at which the object is present, and display controller that causes HUD to display an alert image indicating the position of the object such that the alert image is superimposed on or situated adjacent to the actual position of the object in a view that is observed in a forward direction with respect to the vehicle.
