Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for communicating with road users in the vicinity of semi-automated vehicles are inefficient, as they do not effectively determine the most suitable communication device or method based on the situation, leading to suboptimal communication.
Innovation Solution
A method and device that receive surroundings signals to detect road users and determine the need for communication, selecting the appropriate communication device (visual, acoustic, or wireless) based on the vehicle's actions, environmental conditions, and user behavior, ensuring efficient and personalized communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication devices are available for communicating with road users, then communication versatility is improved, but device complexity and selection difficulty increase
Solution Approach 1:
The communication system automatically selects the appropriate communication device based on detected road user characteristics and environmental conditions without requiring manual intervention. The system evaluates multiple communication devices and autonomously determines the most suitable one for each specific situation, enabling self-service operation.
Solution Approach 2:
The system uses detection results from surroundings signals and road user characteristics to provide feedback for selecting the appropriate communication device. This feedback mechanism allows the system to adaptively choose communication methods based on real-time conditions, resolving the complexity of device selection through intelligent decision-making.
2Speed
If communication is initiated without analyzing road user context, then communication speed is improved, but communication effectiveness deteriorates
Solution Approach 1:
The system performs preliminary detection and analysis of road user characteristics and environmental conditions before initiating communication. By pre-processing surroundings signals and identifying relevant road users in advance, the system prepares communication parameters beforehand, enabling rapid yet effective communication initiation without compromising effectiveness.
3Reliability
If communication devices are continuously activated to ensure coverage, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The communication system dynamically activates only the necessary communication devices based on detected road user characteristics and situational context. Instead of continuous activation, the system adapts its communication device selection in real-time, activating devices only when and where needed, thereby maintaining reliable coverage while minimizing energy consumption.

AI summary
A method for communicating with a road user located in the surroundings of a motor vehicle driven in at least a semi-automated manner. The method includes: receiving surroundings signals; processing the surroundings signals to detect a road user; upon detection of a road user, ascertaining whether a need to communicate with the road user exists; if a need to communicate with the road user exists, ascertaining at least which communication device of a communication device of the motor vehicle, on the motor vehicle side, and of a communication device of an infrastructure, on the infrastructure side, in which the motor vehicle and the road user are located, is to be used in order to communicate with the road user; generating control signals for controlling the communication device(s) to control the communication device(s) to communicate with the road user based on the control signals; and outputting the generated control signals.
