Variable Headlight Illumination for Overlooked Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems fail to effectively assist drivers in detecting objects in their vicinity, particularly in less critical situations, leading to increased risk of accidents due to overlooked obstacles or other road users.
Innovation Solution
A method utilizing environment sensors and driver sensors to create lists of detected and undetected objects, with targeted illumination by controllable headlights to draw the driver's attention to overlooked objects, employing AI for relevance and priority assessment and intermittent flashing to avoid distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all detected objects are displayed in the head-up display, then the driver receives comprehensive information about the traffic situation, but the driver's attention is分散 and the driver may not actually detect or perceive the objects
Solution Approach 1:
The patent extracts only the most critical overlooked objects for illumination based on priority assessment, rather than displaying all detected objects. The control unit determines which objects have the highest priority for driver attention and illuminates only those specific objects using the headlight system, thereby concentrating the driver's attention on the most important information.
Solution Approach 2:
The patent applies local quality by providing enhanced illumination specifically at the location of critical overlooked objects rather than uniformly illuminating all objects. The headlight system targets specific spatial locations corresponding to high-priority objects, creating localized attention guidance that improves detection precision without overwhelming the driver.
2Reliability
If the headlight continuously illuminates overlooked objects, then the driver's attention is consistently directed to these objects, but the driver may become distracted or overwhelmed
Solution Approach 1:
The patent implements periodic action by illuminating critical overlooked objects intermittently rather than continuously. The control unit activates the headlight illumination in periodic cycles, providing sufficient visual cues to maintain driver awareness while allowing periods of normal operation that prevent driver overload and maintain comfort.
3Measurement precision
If the motor vehicle uses sensors to detect objects and driver gaze behavior, then the system can identify overlooked objects, but the system complexity increases
Solution Approach 1:
The patent applies universality by using the existing headlight system for a dual purpose: its primary illumination function and an additional function of selectively highlighting overlooked objects. This multi-functional approach allows the system to achieve sophisticated object detection and attention guidance without proportionally increasing device complexity, as the headlight infrastructure serves multiple roles.
Solution Approach 2:
The patent merges the object detection system, driver gaze monitoring system, and headlight control into an integrated attention guidance system. The control unit combines data from environment sensors and driver sensors to automatically determine and illuminate critical overlooked objects, merging multiple subsystems into a coordinated whole that reduces overall system complexity through integration.
4Loss of information
If the system illuminates all overlooked objects, then the driver receives complete information about potential hazards, but the most critical objects may be lost among less important ones
Solution Approach 1:
The patent applies segmentation by dividing the set of overlooked objects into priority segments. The control unit assesses each overlooked object's priority level and segments them into different categories, then selectively illuminates only the highest priority segments. This segmentation approach ensures that critical objects receive focused attention while less important objects are appropriately deprioritized.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting the illumination parameters (intensity, duration, timing) based on the priority assessment of each overlooked object. High-priority objects receive enhanced illumination parameters to ensure driver attention, while the system modifies illumination characteristics according to the specific traffic situation and object criticality.

Data Source
AI summary
A method is provided for assisting a driver of a motor vehicle in a traffic situation with regard to objects relevant to the traffic situation. The motor vehicle has at least one environment sensor directed towards the forefield of the motor vehicle, at least one driver sensor designed to detect the line of sight and fixation of the driver's eyes, and at least one headlight having a controllably variable spatial illumination pattern. The method includes detecting, classifying, and locating objects in the forefield of the motor vehicle to determine a first object list having the object data associated with the detected objects. The method also includes determining objects, which were detected and not detected by the driver, in order to generate a second object list of undetected objects. The method also includes illuminating the at least one illuminated object in a targeted manner using the at least one headlight to notify the driver about the illuminated object.
