Vehicle Risk Detection Using Cameras, UWB, and Digital Key Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle security technologies primarily react after an incident occurs, lacking proactive detection and notification of potential dangers or suspicious individuals, and do not effectively utilize surrounding images for real-time risk assessment and user notification.
Innovation Solution
A vehicle system equipped with cameras, an external speaker, and a communicator that determines the risk level of a situation, controls an Ultra Wide Band module for obstacle detection, and transmits images and messages to a digital key or external servers for proactive alerting and storage, enabling real-time monitoring and notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle security technology uses post-accident image storage and simple theft alarm notification, then the system structure remains simple, but the security effectiveness is insufficient as it only provides follow-up actions after incidents occur
Solution Approach 1:
The system performs preliminary actions by proactively detecting suspicious persons and dangerous situations before incidents occur. The controller continuously monitors surrounding images through multiple cameras, performs suspect determination algorithms to identify potential threats, and issues advance warnings to users through digital keys and external speakers, enabling preventive security measures rather than reactive responses
Solution Approach 2:
The security system is segmented into multiple functional modules including image capture units (front, rear, side cameras), processing units (controller with suspect determination algorithm), notification units (digital key, external speaker), and communication units (communicator for server interaction). This segmentation allows each module to perform specialized functions while working together to provide comprehensive proactive security
2Reliability
If the system proactively detects and notifies dangerous situations using multiple cameras and communication devices, then security effectiveness improves, but energy consumption increases due to continuous operation of cameras and processing units
Solution Approach 1:
The system implements periodic action by controlling cameras to operate in alternating states of activation and standby. The controller periodically activates specific cameras based on detection needs, processes images at intervals, and issues warnings only when suspicious persons or dangerous situations are detected, rather than maintaining continuous high-power operation of all components
Solution Approach 2:
The system dynamically adjusts the operational state of cameras and processing units based on real-time detection needs. The controller activates additional cameras or increases processing intensity only when suspicious activity is detected, and reduces power consumption during normal conditions, creating a dynamic balance between security effectiveness and energy usage
3Loss of time
If the system transmits captured images to multiple devices (digital key, server) and performs real-time analysis, then the ability to provide timely alerts improves, but the complexity of data management and communication increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing communication channels and data transmission protocols before incidents occur. Image data is pre-processed and prepared for transmission, and communication pathways to digital keys and servers are pre-configured, enabling immediate alert issuance when threats are detected without delays in data management setup
Solution Approach 2:
The controller serves as an intermediary that centralizes image capture, processing, and distribution functions. It receives images from multiple cameras, performs suspect determination algorithms, and selectively transmits relevant data to digital keys, external speakers, and servers, thereby simplifying data management complexity while maintaining rapid alert response capabilities

AI summary
A vehicle includes a plurality of cameras configured to capture a surrounding situation of the vehicle, an external speaker configured to output a sound to the outside of the vehicle, a communicator configured to communicate with a first server, and a controller configured to determine a degree of risk of the dangerous situation based on the degree of risk based on a case where a dangerous situation is captured through the plurality of cameras, to control an Ultra Wide Band (UWB) module to detect obstacles around the vehicle, to control at least one of a digital key and an external speaker to output a message for the dangerous situation or an image in which the dangerous situation is captured, and to transmit the image in which the dangerous situation is captured to the first server through the communicator.
