Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting systems struggle to evenly illuminate the lateral regions of a vehicle, making it difficult to detect road markings and obstacles, especially at night, which hinders advanced driver assistance systems for autonomous vehicles.
Innovation Solution
A lighting system comprising a first rear light module and a second front light module, emitting intersecting beams that overlap to cover a rectangular lateral area adjacent to the vehicle, combined with an image capture device for obstacle and marking detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional headlamps are positioned only at the front of the vehicle, then the headlamp assembly is simple and compact, but the lateral regions adjacent to the vehicle cannot be adequately illuminated
Solution Approach 1:
The headlamp system is divided into separate front headlamps and lateral headlamps that can be independently positioned and controlled. The lateral headlamps are specifically positioned at the lateral regions of the vehicle to illuminate areas adjacent to the vehicle, separating the illumination function into distinct spatial zones.
Solution Approach 2:
The headlamp arrangement transitions from a traditional single-plane front-facing configuration to a multi-dimensional arrangement that includes lateral positioning. The lateral headlamps extend the illumination coverage into the lateral spatial dimension, creating comprehensive three-dimensional lighting coverage around the vehicle.
2Illumination intensity
If multiple headlamps are positioned at different locations including lateral regions, then comprehensive illumination coverage is achieved, but the headlamp assembly becomes more complex
Solution Approach 1:
The headlamp system is designed to perform multiple functions: front headlamps provide primary forward illumination while lateral headlamps provide lateral region illumination. Both types of headlamps can operate independently or in combination, allowing the system to adapt to different driving conditions and illumination requirements.
Solution Approach 2:
Different regions of the vehicle are illuminated by headlamps with specific positioning and directional characteristics optimized for their respective zones. Front headlamps are optimized for forward road illumination while lateral headlamps are optimized for illuminating areas adjacent to the vehicle, with each position providing locally optimized lighting quality.
3Illumination intensity
If headlamps are positioned to illuminate lateral regions, then visibility in adjacent areas improves, but glare to other road users may increase
Solution Approach 1:
The lateral headlamps are positioned and directed to provide localized illumination specifically for lateral regions adjacent to the vehicle, with their beam patterns optimized to illuminate areas that would otherwise be in shadow while minimizing light projection into the paths of other road users.
Solution Approach 2:
The lighting system incorporates control logic that monitors driving conditions and adjusts the operation of lateral headlamps accordingly, activating them when lateral illumination is needed while deactivating or dimming them when they may cause glare to other road users, creating a responsive adaptive lighting system.
