Vehicle Warning Transmission Control via Contextual Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for transmitting warning messages, such as those for wrong-way drivers, often result in high data loads and power consumption, leading to potential message overload and confusion, especially in dynamic traffic situations.
Innovation Solution
A method and device that control the transmission of warning messages based on context information, such as vehicle velocity, route course, and status of approaching vehicles, to optimize message propagation and reduce unnecessary transmissions through a communication interface and data server, thereby minimizing data load and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If warning messages are transmitted continuously to all vehicles, then the warning coverage is improved, but the data load and power consumption increase
Solution Approach 1:
The patent applies local quality by transmitting warning messages selectively to specific vehicles based on their individual context (location, speed, direction) rather than broadcasting to all vehicles uniformly. The control unit determines which vehicles receive warnings based on matching their contextual parameters with the hazard situation, thereby reducing overall data load while maintaining effective warning coverage for at-risk vehicles.
Solution Approach 2:
The patent implements partial action by transmitting warning messages only to the subset of vehicles that are actually at risk, rather than to all vehicles in the network. The system identifies and targets only those vehicles whose context matches the hazardous situation parameters, avoiding unnecessary transmissions to vehicles not affected by the hazard.
2Reliability
If warning messages are transmitted to all vehicles, then the warning coverage is improved, but the power consumption increases
Solution Approach 1:
The patent reduces power consumption by applying local quality - transmitting warnings only to specific vehicles based on their contextual match with the hazard rather than universal broadcasting. The control unit evaluates each vehicle's context (position, speed, trajectory) and activates transmission only when relevant, significantly reducing the energy expenditure of the communication system while preserving warning effectiveness for affected vehicles.
Solution Approach 2:
The system applies partial action by limiting warning transmissions to only those vehicles that require alerting based on their contextual parameters. This selective approach reduces the total number of transmissions and associated power consumption compared to blanket broadcasting, while ensuring all at-risk vehicles receive appropriate warnings.
3Quantity of substance
If context information is processed to control transmission, then the data load is reduced, but the device complexity increases
Solution Approach 1:
The patent applies self-service by enabling vehicles to autonomously determine their own reception status based on their contextual parameters (location, speed, direction) and the hazard information. Each vehicle's control unit independently evaluates whether it should receive the warning message by comparing its context with the hazard parameters, eliminating the need for centralized control and reducing overall system complexity despite the added processing at individual vehicle levels.
Solution Approach 2:
The system implements preliminary action by pre-defining contextual parameters and transmission criteria before actual hazard events occur. The control logic is pre-configured with the rules for determining when and to whom warnings should be transmitted, allowing for automated decision-making without complex real-time analysis, thereby reducing operational complexity while maintaining effective data load reduction.
Data Source
AI summary
A method for controlling a transmission behavior for transmitting a warning message for a vehicle. In this case, a warning message for warning a driver of the vehicle about a hazardous situation is initially read in. Furthermore, a piece of context information about a context in which the warning message was generated is received. In a further method step, a control signal for controlling a transmission of the warning message via a communication interface of the vehicle and/or a vehicle-external data server connected to the communication interface is provided as a function of the piece of context information.
