Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles without advanced driver assistance system (ADAS) functions or with weak ADAS functions cannot fully benefit from new ADAS technologies, and those without communication functions are unable to receive advanced ADAS capabilities.
Innovation Solution
An external module that connects to a vehicle, providing an interface for data exchange, a processor to acquire and transmit ADAS information, and a communication unit for wireless data exchange with terminals and servers, enabling the display of ADAS functions and controlling the vehicle's systems to implement these functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ADAS functions are not mounted in a vehicle, then the vehicle structure remains simple and cost-effective, but the vehicle cannot receive the benefits of advanced driver assistance technologies
Solution Approach 1:
The patent divides the ADAS system into two separate components: a vehicle unit mounted in the vehicle and an external server unit. The vehicle unit contains minimal hardware (sensor interface, processor, communication interface) while the external server handles complex ADAS processing and database storage. This segmentation allows the vehicle to gain ADAS functionality without incorporating complex systems internally.
Solution Approach 2:
The patent introduces a communication interface as an intermediary between the vehicle unit and the external server. This intermediary enables data exchange and remote ADAS functionality without requiring direct physical integration of complex systems into the vehicle, resolving the contradiction between functionality and complexity.
2Adaptability or versatility
If communication functions are not mounted in a vehicle, then the vehicle structure remains simple, but the vehicle cannot receive advanced ADAS capabilities through data exchange
Solution Approach 1:
The patent extracts the complex communication and processing functions from the vehicle and places them in an external server. The vehicle unit retains only essential communication interfaces for data exchange, while advanced ADAS capabilities are delivered remotely through the communication network, avoiding the need to integrate complex communication systems into the vehicle.
Solution Approach 2:
The external server provides multi-functional ADAS services to multiple vehicles through a universal communication interface. A single server can serve multiple vehicles, providing advanced ADAS capabilities without each vehicle needing its own complete ADAS system, thus reducing individual vehicle complexity while maintaining versatility.
3Adaptability or versatility
If sensors are not mounted on a vehicle, then the vehicle structure remains simple, but the vehicle cannot acquire surrounding information for ADAS functions
Solution Approach 1:
The patent uses the communication interface as an intermediary to acquire surrounding information. Instead of mounting physical sensors in the vehicle, the system uses communication channels to receive environmental data from external sources, eliminating the need for complex sensor integration while maintaining ADAS functionality.
Solution Approach 2:
The system creates a virtual representation of the surrounding environment through data received via communication interfaces rather than physical sensors. The processor generates ADAS information based on communicated data, effectively copying environmental information without requiring physical sensing hardware in the vehicle.
Data Source
AI summary
The present invention relates to an external module comprising: an interface physically connected to a vehicle so as to exchange data with the vehicle; and a processor for receiving peripheral information of the vehicle and state information of the vehicle through the interface, acquiring the ADAS information, on the basis of the peripheral information of the vehicle and the state information of the vehicle, and performing control so as to allow a display inside the vehicle to display the ADAS information by transmitting the ADAS information, through the interface, to the vehicle.
