Problem
Existing driver assistance systems are vehicle-specific, making them difficult to retrofit across different types and sizes, and require complex calibration processes.
Innovation Solution
A reconfigurable advanced driver assistance device with a single housing unit containing a common module that adjusts vertically, featuring stereoscopic and long-range cameras, a LiDAR module, and a microphone array, allowing for universal compatibility and adjustable parameters to suit various vehicles, including left- and right-hand driven vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If driver assistance systems are in-built into the vehicle, then the system is already calibrated and integrated, but the system cannot be utilized for any other vehicle and requires sophisticated calibration tools
Solution Approach 1:
The patent implements a universal driver assistance system with standardized mounting brackets and housing that can be retrofitted to multiple vehicle types. The common module design with adjustable positioning allows the same device to serve different vehicle models without requiring vehicle-specific calibration tools, making the system multi-functional across various platforms.
Solution Approach 2:
The system incorporates adjustable mounting mechanisms that allow dynamic repositioning of the common module and camera assemblies. This dynamic adjustment capability enables the system to adapt to different vehicle geometries and sensor requirements, eliminating the need for complex fixed calibration procedures for each vehicle type.
2Device complexity
If a single housing unit with common module is used, then the device structure is simplified, but the system must accommodate multiple camera types and functions
Solution Approach 1:
The patent divides the driver assistance system into a common module housed in a single unit and separate interchangeable camera modules. This segmentation allows the housing structure to remain simple and standardized while the camera modules can be customized and swapped to match different detection requirements, resolving the conflict between structural simplicity and functional versatility.
Solution Approach 2:
The common module is designed as a universal platform that can accommodate multiple types of camera modules through standardized interfaces and mounting mechanisms. This universal design enables a single housing structure to support various camera configurations for different detection ranges and fields of view without requiring complex vehicle-specific adaptations.
3Adaptability or versatility
If multiple camera modules with different focal lengths are used, then the detection range is extended, but the number of components increases
Solution Approach 1:
The patent combines multiple camera modules with different focal lengths (wide-angle for close-range and narrow-angle for long-range detection) into a single integrated common module housing. This merging approach consolidates what would otherwise be separate components into one unified assembly, extending detection range without proportionally increasing the number of discrete components or mounting points.

AI summary
The present invention provides a vehicle mountable universal driver assistance device. This device includes a housing unit encasing a common module on which are mounted a first camera module, a second camera module, different from the first camera module, and a ranging module. The common module may be moved along an axis to adjust the viewing angle of the first camera, second camera and ranging module. The device can be mounted on windshield of any vehicle and can be calibrated accordingly. The intensity and frequency of the warning alert from the warning display device are based on the ambient noise level of the driver.
