ADAS Collision Warning From Door Unlock to Safe Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional advanced driver assistance systems (ADAS) do not operate when the user is not riding or when the vehicle's engine is turned off, limiting their functionality.
Innovation Solution
An advanced driver assistance system that determines the user's riding intention and communicates with an obstacle detector and a processor to assess collision possibilities with other vehicles, providing notification and controlling autonomous driving and parking to a safe area, even when the user is not inside the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ADAS operates only when the user is riding or the engine is on, then the system complexity and energy consumption are reduced, but the safety coverage and functionality are limited
Solution Approach 1:
The ADAS is designed to perform multiple functions across different operating states: it provides collision warning when the user is approaching the vehicle (before engine start), and continues to provide collision avoidance and autonomous parking functions when the engine is running. This multi-functional design expands safety coverage without requiring separate systems for different states.
Solution Approach 2:
The system performs preliminary collision assessment when the user is approaching the vehicle and the door is being unlocked, before the engine is actually started. This preliminary action allows the system to prepare safety measures in advance, such as detecting obstacles and calculating collision risks, so that protection is already in place when the user enters the vehicle.
2Adaptability or versatility
If the ADAS operates only when the user is riding or the engine is on, then the energy consumption is reduced, but the usability and functionality are limited
Solution Approach 1:
The ADAS operates in periodic cycles corresponding to different user states: it activates for collision warning when the user approaches and unlocks the door, then transitions to collision avoidance and autonomous parking functions when the engine is running. This periodic activation based on user presence and engine state provides comprehensive functionality while avoiding continuous operation and excessive energy consumption.
3Reliability
If the system provides comprehensive collision assessment and autonomous driving control, then the safety and user protection are improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple safety functions (collision warning, collision avoidance, autonomous parking) into a single integrated ADAS architecture. The processor coordinates all these functions by receiving data from various sensors (obstacle detector, image obtainer, communicator) and executing appropriate responses based on the current operating state, thereby providing comprehensive protection without requiring entirely separate systems for each function.
Solution Approach 2:
The processor acts as an intermediary that coordinates between different sensors (obstacle detector, image obtainer, communicator) and different output devices (notification system, autonomous driving controller). It receives data from multiple sources, processes the information to assess collision risk, and directs appropriate responses, thereby simplifying the overall system architecture while maintaining comprehensive safety functionality.

AI summary
An advanced driver assistance system is provided. The advanced driver assistance system of the vehicle comprises a communicator configured to communicate with an obstacle detector configured to detect an obstacle; and a processor configured to determine a riding intention of a user in response to reception of a door unlocking instruction, obtain location information of other vehicles based on obstacle information detected by the obstacle detector in response to determining that the riding intention exists, determine a collision possibility with other vehicles based on the location information of other vehicles, and control output of notification information for a collision in response to determining that the collision possibility exists.
