Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ADAS uses only onboard sensors for collision detection, then the system structure remains simple, but the sensing range is limited and collision risk detection accuracy deteriorates
Solution Approach 1:
The patent merges onboard sensors with cloud platform resources and other vehicles' sensing data to create a collaborative detection system. The cloud platform aggregates location and traveling status information from multiple vehicles, enabling extended sensing range and improved collision risk detection accuracy beyond what single-vehicle sensors can achieve.
Solution Approach 2:
The cloud platform acts as an intermediary between vehicles, collecting, processing, and distributing collision risk information. It receives data from multiple vehicle terminals, performs centralized analysis, and transmits warning messages to relevant vehicles, thereby extending the effective sensing range and improving detection accuracy.
2Area of stationary object
If ADAS implements multi-vehicle collaboration for extended sensing range, then the sensing range is expanded, but the system complexity and communication requirements increase
Solution Approach 1:
The cloud platform serves as a centralized intermediary that manages the complexity of multi-vehicle collaboration. It handles data collection, processing, and distribution, thereby extending the sensing range without requiring complex peer-to-peer communication systems in each vehicle.
Solution Approach 2:
Each vehicle terminal independently transmits its location and traveling status information to the cloud platform using existing communication interfaces. The vehicles self-serve by providing their sensing data without requiring complex coordination protocols, simplifying the overall system architecture.
3Reliability
If FCW messages are transmitted to all vehicles in the network, then the collision risk coverage is improved, but the communication resource consumption and network load increase
Solution Approach 1:
The cloud platform determines transmission targets based on local conditions of each vehicle terminal, including its communication capabilities and collision risk level. FCW messages are selectively transmitted only to vehicles that need the warning information, optimizing communication resource usage while maintaining reliable collision risk coverage.
Solution Approach 2:
The transmission mode is dynamically adjusted based on the communication capabilities of target vehicles. The system adapts transmission strategies in real-time, selecting appropriate communication interfaces and modes for each recipient to minimize resource consumption while ensuring reliable message delivery.
Data Source
AI summary
A driving assistance processing method is provided. In the method, location information and traveling status information of a plurality of vehicle terminals are obtained. A forward collision warning (FCW) message is generated in response to detecting that a specified vehicle terminal of the plurality of vehicle terminals has a potential collision risk. The potential collision risk is detected based on the location information of at least the specified vehicle terminal and the traveling status information of at least the specified vehicle terminal. A transmission mode of the FCW message is determined based on communication capabilities of the plurality of vehicle terminals included in an FCW vehicle set of the specified vehicle terminal. The FCW message is transmitted to the plurality of vehicle terminals included in the FCW vehicle set in the determined transmission mode. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.
