Vehicle Headlight Range Adjustment via Distance-Based Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle headlight systems require manual switching between low and high beams, leading to delayed or missed changes due to driver fatigue or distraction, causing potential blinding of other road users and reduced visibility for the driver.
Innovation Solution
A method for automatically adjusting the headlight range from low to high beam based on a predetermined distance traveled after a reason for low beam operation is omitted, using an environment detection device to determine when it is safe to activate the high beam without dazzling other road users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver manually switches between low beam and high beam, then the headlight range can be adjusted, but the driver's concentration and attention are required continuously, leading to delayed or missed changes due to fatigue or distraction
Solution Approach 1:
The lighting system performs the switching operation automatically based on detected road user positions and predetermined distances, eliminating the need for driver intervention. The system monitors the environment and self-adjusts the headlight range without requiring driver attention or manual input.
Solution Approach 2:
The system continuously detects the positions of other road users and uses this feedback information to determine when to switch between low and high beam modes. The switching decision is based on real-time spatial relationships and predetermined distance criteria, ensuring timely and appropriate headlight adjustment.
2Illumination intensity
If the high beam is activated immediately when another road user is detected to leave the glare zone, then the driver's visibility is improved, but the other road user may still be within the glare zone and blinded
Solution Approach 1:
The system waits for a predetermined distance to be traveled after the road user leaves the detection range before activating the high beam. This preliminary waiting period ensures that the high beam is only activated when it is certain that other road users are no longer in the glare zone, preventing harmful glare while maintaining optimal visibility.
3Object-affected harmful factors
If the driver continues to use low beam after passing another road user, then glare to other road users is reduced, but the driver is flying blind and can only recognize hazards inadequately and too late
Solution Approach 1:
The lighting system automatically determines when to switch from low beam to high beam based on the absence of other road users in the detection range and the travel of a predetermined distance. This automatic switching ensures optimal hazard recognition without requiring driver intervention or manual input.
4Object-affected harmful factors
If a predetermined distance is waited before activating high beam, then the high beam activation is delayed, but this prevents blinding other road users who may still be in the glare zone
Solution Approach 1:
The system implements a predetermined distance-based waiting period before high beam activation. This preliminary action ensures that the high beam is only activated when it is certain that other road users have completely left the glare zone, preventing harmful glare while minimizing the delay through objective distance-based criteria.

AI summary
The invention relates to a method for increasing the light range of a vehicle (100), comprising a step of receiving full-beam-activation information via an interface, the full-beam-activation information displaying a possibility for the anti-dazzle operation of the main beam (104). The method also comprises a step of determining a distance covered by the vehicle, in response to the reception of the full-beam-activation information, and a step of providing range-increasing information for increasing the headlight range when the covered distance following the reception of the full-beam-activation information is longer than a pre-determined minimum distance and/or a step of providing at least one value for increasing the light range (light-range-increasing value) according to the distance covered.
