Vehicle Feed System Remote Mode Selection via Wireless Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users cannot conveniently select the HV feed mode for electric power feeding from a remote location, as they need to confirm the vicinity of the vehicle before starting the engine, and existing systems lack remote operation capabilities for power feed mode selection.
Innovation Solution
A feed system with a vehicle equipped with an engine, electric power generating device, electric storage device, outlet, and wireless communication device, allowing selection of feed modes (HV and EV) using a portable terminal via direct or relayed communication systems, enabling remote operation and ensuring safe engine activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user selects HV feed mode using a portable terminal from a remote location, then the convenience of operation is improved, but the safety of engine activation is compromised because the user cannot confirm the vicinity of the vehicle
Solution Approach 1:
The patent introduces a relay device as an intermediary between the portable terminal and the vehicle. This relay device receives selection information from the portable terminal and transmits it to the vehicle, enabling remote operation while maintaining safety controls. The relay device acts as a trusted mediator that facilitates communication without requiring the user to be physically present near the vehicle.
Solution Approach 2:
The system performs preliminary verification of communication establishment before allowing HV feed mode selection. The vehicle controller checks whether communication with the portable terminal is properly established and validates the selection request before enabling the HV feed mode. This preliminary action ensures that only authenticated and verified operations can activate the engine, maintaining safety while enabling remote operation.
2Ease of operation
If the system allows HV feed mode selection without communication verification, then the ease of operation is improved, but the reliability of mode selection is worsened
Solution Approach 1:
The vehicle controller provides feedback by checking whether communication with the portable terminal is established before allowing HV feed mode selection. The system monitors the communication state and only permits mode selection when proper communication is confirmed. This feedback mechanism ensures reliable mode selection while maintaining operational simplicity for authenticated users.
3Reliability
If the system uses only direct communication (first communication system), then the reliability of communication is improved, but the adaptability to remote operations is worsened
Solution Approach 1:
The patent implements a dual communication system that supports both direct communication (first communication system) and relayed communication (second communication system via relay device). This multi-functional communication architecture allows the system to adapt to different operational scenarios: direct communication for nearby operations and relayed communication for remote operations, thereby achieving both reliability and versatility.

AI summary
A feed system (2) includes a vehicle (1) and a feed mode controller (302). The feed system feeds electric power to an electric load (202) outside the vehicle in a first feed mode or a second feed mode. A wireless communication device (130) of the vehicle (1) communicates in a first communication system in which communication with a portable terminal (300) is established without passing through a relay point (404, 406, 402, 204). The feed mode controller enables the first feed mode to be selected when the communication in the first communication system is established, and disables the first feed mode from being selected when the communication in the first communication system is not established.
