초록

An apparatus and method is provided for detecting the level, composition, and temperature of a liquid fuel stored in a tank on a vehicle, as well as the tank pressure, and for transmitting this data via a multiplex bus to a central vehicle computer. The apparatus for collecting liquid fuel level data comprises first capacitive sensing means located within the fuel tank for storing a charge proportional to a full liquid level, second capacitive sensing means located within the tank for storing an instant liquid level charge proportional to the instant liq...

청구항

A method for collecting liquid level data from at least two capacitive sensors and a resistive member located within a storage tank in a vehicle, wherein a first capacitive sensor is disposed so as to be always immersed in a liquid within said storage tank, and a second capacitive sensor is disposed so as to be exposed to a changing liquid level within stud storage tank, comprising the steps of: (a) charging said first and second capacitive sensors; (b) discharging said first capacitive sensor through a resistive member and recording the discharge time a...
