Solution Overview

Problem

Existing vehicle lighting systems, including adaptive front-lighting systems, fail to effectively illuminate areas to the side of the vehicle, limiting safety and comfort, especially during turns and in low visibility conditions.

Innovation Solution

A vehicle exterior rearview system with adaptive lighting modules, including LEDs and optical elements, that provide additional lighting sectors for turn-signal indicators, adaptive cornering lights, and security lights, controlled by a system receiving vehicle and environmental data to dynamically adjust lighting based on conditions, allowing for user customization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If headlamps are mounted in fixed positions on the vehicle, then the lighting system structure is simple, but areas to the side of the vehicle cannot be illuminated

Engineering Contradiction:
Improveside area illuminationVSAvoidlighting system structure
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The lighting system is segmented into multiple independent lighting modules, each capable of illuminating different sectors (front, side, rear). These modules are distributed across different vehicle locations including exterior mirrors, allowing side areas to be illuminated without requiring complex mechanical movement of traditional headlamps

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lighting modules are designed with multi-functionality, serving as turn-signal indicators, adaptive cornering lights, and security lights simultaneously. This universal design allows a single module to perform multiple lighting functions that would traditionally require separate systems

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Illumination intensity

If additional lighting modules are added to illuminate side areas, then side area visibility is improved, but the device complexity increases

Engineering Contradiction:
Improveside and rear area illuminationVSAvoidnumber of lighting modules
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

Multiple lighting functions (turn-signal indicator, adaptive cornering light, security light) are merged into single integrated lighting modules. Each module contains multiple lighting sectors that can be independently controlled, reducing the total number of separate components needed while achieving comprehensive illumination

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lighting modules provide targeted illumination only when needed (during turns, in low visibility conditions, or when security lighting is required) rather than continuous full-coverage lighting. This partial action approach reduces the overall lighting system complexity while maintaining adequate illumination when required

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If lighting modules provide multiple functions (turn-signal, cornering light, security light), then system versatility is improved, but control complexity increases

Engineering Contradiction:
Improvelighting function versatilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lighting modules feature dynamic control capabilities where lighting sectors can be independently activated or deactivated based on driving conditions. The control system dynamically adjusts which lighting functions are active (e.g., activating only cornering light during turns, or security light when vehicle is stationary) rather than requiring all functions to operate simultaneously

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control system receives feedback from vehicle sensors (steering angle, brake status, ambient light conditions) and automatically adjusts lighting module operation accordingly. This feedback mechanism allows the system to provide versatile lighting functions without requiring complex manual control, as the system autonomously selects appropriate lighting modes based on real-time vehicle state

Inventive Principle:
Principle #23Feedback

AI summary

An adaptive cornering light system for a motor vehicle includes an exterior mirror head, housing at least one lighting module that having a plurality of LEDs arranged in sectors to provide different lighting functionalities. One LED or light sector is provided for adaptively illuminating a cornering area that extends along the side of the vehicle toward the front of the exterior mirror head. This “cornering LED” is adaptively activated if the speed of the vehicle is below a threshold speed, or in response to additional optional parameters such as steering angle, turn-signal blinker activation, and running lights activation. Another LED or light sector may be used as a security light to illuminate or display a message on the ground in the door area adjacent the side of the vehicle. Interior lights are also disclosed. User input may also control options for illumination.
