Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems for commercial and industrial vehicles rely on multiple dedicated sensors to determine their operational design domain, increasing cost and complexity, and are inaccurate outside their rated conditions.
Innovation Solution
An image-based operational domain detection system using a vehicle controller with channels analyzing camera images to determine the operational domain, potentially supplemented by sensor signals, and comparing it to the rated domain to prevent unsafe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple dedicated sensors are used to determine operational design domain, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The existing camera system is made multi-functional by enabling it to perform both its original function (capturing images for driver assistance) and a new function (determining operational design domain). The controller processes camera images to detect environmental conditions, road types, and weather, eliminating the need for dedicated sensors while utilizing already-deployed hardware infrastructure.
Solution Approach 2:
The patent combines the operational domain detection function with the existing camera system. Instead of separate dedicated sensors for detecting weather, road conditions, and environment, the system merges these detection capabilities into the image processing pipeline of the camera, consolidating multiple functions into a single sensor system.
2Measurement precision
If multiple dedicated sensors are used to determine operational design domain, then measurement precision is improved, but cost increases
Solution Approach 1:
The camera system is made multi-functional to serve both driver assistance imaging and operational domain detection purposes. This eliminates the need to manufacture and install separate dedicated sensors, thereby reducing overall system cost while maintaining detection accuracy through sophisticated image analysis algorithms.
3Device complexity
If existing cameras are used for operational domain detection, then device complexity is reduced, but measurement precision may deteriorate
Solution Approach 1:
The patent replaces physical dedicated sensors with an information processing approach. Instead of using separate mechanical/electronic sensors for detecting weather, road conditions, and environment, the system uses image processing algorithms to extract this information from camera images, substituting a computational system for physical sensing hardware.
Solution Approach 2:
The camera images serve as an intermediary medium that carries information about the operational environment. Rather than directly measuring environmental parameters with dedicated sensors, the system uses images as an intermediate representation from which operational domain characteristics are inferred through image analysis.
