Dynamic Driving Envelope Adaptation for Collision Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current collision prediction systems for motor vehicles are inadequate in warning of potential collisions with objects outside the immediate surrounding area, particularly pedestrians, and do not effectively adapt to dynamic vehicle and environmental parameters, leading to delayed reaction times and increased accident risks.
Innovation Solution
A system that uses sensors to monitor the driving path and dynamically adapt the monitored area by enlarging the reaction range beyond the physical vehicle width, incorporating safety zones and environmental parameters like vehicle speed, object speed, and environmental brightness to initiate safety-related actions before the object is in the collision path, utilizing known components and functions of a normal motor vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the monitored area is limited to the immediate surrounding area of the motor vehicle, then the system complexity is reduced, but the reaction time to potential collisions is delayed
Solution Approach 1:
The system performs preliminary detection and warning actions by monitoring areas beyond the immediate vehicle surroundings. Sensors detect objects in advance of the vehicle's path, and the control unit issues warnings before the object enters the critical collision zone, enabling early driver response and preventing delayed reactions.
Solution Approach 2:
The system expands the monitored space from a two-dimensional area directly around the vehicle to a three-dimensional volume that extends forward along the driving path. This dimensional expansion allows the system to detect objects at greater distances and provide earlier warnings, resolving the contradiction between monitored area size and reaction time.
2Reliability
If the driving path is dynamically adapted to include safety zones beyond physical vehicle width, then collision detection capability is improved, but the device complexity increases
Solution Approach 1:
The control unit dynamically adapts the monitored driving path based on real-time vehicle parameters (speed, acceleration) and environmental parameters (lighting, road conditions). The safety zones are not fixed but adjust their dimensions and position according to current operating conditions, optimizing collision detection capability while using the existing sensor and control systems.
Solution Approach 2:
The system uses existing multi-functional vehicle components (sensors, control units, warning devices) to achieve enhanced collision detection. The same sensor system serves both standard vehicle operation and extended safety zone monitoring, avoiding the need for entirely separate dedicated systems and thereby limiting the increase in device complexity.
3Reliability
If safety zones are enlarged to cover areas where pedestrians might approach, then traffic safety is improved, but false warning signals increase
Solution Approach 1:
The system applies different monitoring strategies and safety zone dimensions to different spatial locations and object types. Rather than using a uniform safety zone, the control unit adjusts monitoring intensity and warning thresholds based on the specific location, object characteristics, and contextual factors, reducing false warnings while maintaining high safety standards in critical areas.
Solution Approach 2:
The control unit continuously monitors detected objects and adjusts warning signal issuance based on feedback from multiple parameters including object movement patterns, speed, direction, and changes in environmental conditions. This feedback mechanism allows the system to distinguish between objects that pose actual collision risks and those that do not, reducing false warnings while maintaining traffic safety.
