Vehicle Liquid Supply Communication Module for Accurate Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle liquid amount detectors face challenges in accurately detecting the supply of liquid, such as fuel, due to minimal changes in liquid level in the tank, especially for complex tank shapes or when the vehicle is tilted, making it difficult to determine if liquid has been supplied accurately without additional sensors.
Innovation Solution
A supply information communication system that includes a liquid supply facility and a communication module, where the facility measures and transmits supply information, including the amount, unit price, components, and fee of the liquid, to the vehicle, allowing for reliable determination of liquid supply without the need for additional sensors on the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If liquid level detection is used to determine liquid supply, then the detection method is simple, but the detection accuracy deteriorates when the liquid level changes minimally or the vehicle is tilted
Solution Approach 1:
The invention introduces a communication module as an intermediary between the liquid supply facility and the vehicle's control unit. This mediator transmits supply information (including supply amount, unit price, and components) from the supply facility to the vehicle, enabling accurate liquid supply detection without relying on imprecise liquid level measurements, especially when the vehicle is tilted or the tank has a complex shape
Solution Approach 2:
The invention replaces the mechanical/physical liquid level detection method with an electronic information transmission system. Instead of measuring liquid level changes mechanically, the system uses communication modules to receive and process supply information electronically, thereby eliminating the inaccuracies associated with physical level detection in tilted or complex-shaped tanks
2Measurement precision
If additional sensors are installed on the vehicle to accurately detect liquid supply, then the detection accuracy improves, but the device complexity and cost increase
Solution Approach 1:
The liquid supply facility performs self-service by measuring and recording the supply amount, unit price, and components of the liquid supplied. This information is then transmitted to the vehicle via the communication module, eliminating the need for the vehicle to equip its own measurement sensors. The supply facility's measurement system serves both the supply operation and the information provision function
3Device complexity
If liquid level detection is used, then no additional transmission system is needed, but reliable determination of liquid supply cannot be made when liquid level changes are minimal
Solution Approach 1:
The invention establishes a feedback mechanism where the liquid supply facility transmits supply information (including supply amount, unit price, and components) to the vehicle's control unit via the communication module. This feedback loop provides reliable confirmation of liquid supply regardless of liquid level changes, enabling the vehicle to accurately determine supply status, calculate costs, and manage liquid inventory based on received information rather than imprecise level detection

AI summary
A supply information communication system, a communication module, a liquid supply facility, and a supply information communication method are provided. The communication module is mounted on a vehicle to which liquid is supplied from the liquid supply facility. An obtaining section of the liquid supply facility obtains identifying information for identifying the vehicle that is a supply destination of the liquid discharged by a supplying section. A transmitting section of the liquid supply facility transmits supply information to the vehicle identified by the identifying information. The supply information includes information indicating that the liquid has been supplied. The communication module includes a receiving section and a storing section. The receiving section receives the supply information addressed to the vehicle on which the communication module is mounted. The storing section stores the received supply information.
