Vehicle Door Collision Warning System Using Approach Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The risk of approaching objects colliding with an opened automobile side door is not effectively mitigated by existing technologies, as outwardly swinging doors increase the vehicle's width, potentially causing collisions with other vehicles, scooters, bicycles, or humans.
Innovation Solution
A vehicle system comprising an approach sensor, a side door sensor, and a controller that alerts the occupant of a potential collision by detecting an impending door opening and an approaching object, utilizing a timer to ensure warnings are provided when the engine is turned off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the side door swings outward when opened, then the width of the automobile increases, but this increases the risk of collision with approaching objects
Solution Approach 1:
The system performs preliminary detection of approaching objects using sensors (ultrasonic, infrared, or camera-based) before the door is opened. When an approaching object is detected within a predetermined distance, the system activates warning signals (audio alerts, visual indicators, or haptic feedback) to notify the occupant of the collision risk, allowing the occupant to delay or modify the door opening action.
Solution Approach 2:
The system continuously monitors the environment around the vehicle using sensors and provides real-time feedback to the occupant through warning signals. The feedback loop includes: sensor detection of approaching objects, controller processing of distance and speed data, and activation of appropriate warning mechanisms to inform the occupant of potential collision risks during door opening.
2Object-affected harmful factors
If sensors and warning systems are added to detect approaching objects, then collision risk is reduced, but device complexity increases
Solution Approach 1:
The system uses multi-functional sensors that can detect both approaching objects and provide distance measurement. The controller integrates multiple functions including sensor data processing, collision risk assessment, warning signal generation, and system configuration management. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing system complexity while maintaining comprehensive collision risk mitigation capabilities.

AI summary
Systems, automobiles, and methods are provided for warning of a potential collision between an approaching object and an opened side door of a vehicle. A system for a vehicle includes an approach sensor, a side door sensor, an alarm, and a controller. The approach sensor is configured to attach to the vehicle and to generate approach sensor data indicating an approaching object that may collide with a side door of the vehicle. The side door sensor is configured to generate door sensor data indicating an impending opening of the side door by an occupant. The alarm is configured to communicate with the occupant. The controller includes an alert initiation module configured to alert the occupant that the approaching object may collide with the side door in response to detecting the impending opening of the side door and detecting the approaching object.
