Vehicle Attribute Signaling on Request to Cut Battery Drain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle systems face inefficiencies in managing power consumption when continuously or periodically actuating components to output unrequested data, leading to increased battery power consumption.
Innovation Solution
A vehicle computer broadcasts a message identifying attributes and only actuates components to output light or sound upon receiving a specific request from a remote computer, reducing unnecessary power usage by selectively activating components based on user inputs and requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicle components are continuously or periodically actuated to output data, then data sharing capability is improved, but power consumption increases
Solution Approach 1:
The system transitions from continuous actuation to periodic actuation by only activating vehicle components when specific requests are received from remote computers. The vehicle computer monitors for requests and triggers component actuation only when needed, creating a demand-driven periodic action pattern that reduces unnecessary power consumption while maintaining data sharing capability.
Solution Approach 2:
The vehicle system implements self-service by autonomously monitoring for data requests from remote computers and selectively actuating components based on received requests. The system serves itself by managing its own power consumption through intelligent request monitoring and conditional actuation, eliminating the need for continuous external control while optimizing energy usage.
2Use of energy by moving object
If vehicle components are selectively actuated based on requests, then power consumption is reduced, but data responsiveness may be delayed
Solution Approach 1:
The vehicle computer continuously monitors for data requests from remote computers, maintaining a ready state for receiving requests without continuously actuating components. This preliminary monitoring action ensures that when a request arrives, the system can respond immediately by actuating the appropriate components, thus reducing response time while avoiding continuous power consumption.

AI summary
A first message is broadcasted to a plurality of remote computers identifying an attribute of a host vehicle. A second message including a request to receive data about the identified attribute in response to broadcasting the first message is received from one of the remote computers. Upon receiving the second message, a host vehicle component is actuated to output at least one of light or sound associated with the identified attribute.
