A method for detecting the filling level in a motor vehicle. A device for ascertaining the tank filling level value of moving vehicles, including at least one tank, at least one filling level sensor, at least one control unit and at least one pump. 1. A device for ascertaining the tank filling level value of moving vehicles , comprising:at least one tank;at least one filling level sensor;at least one control unit; andat least one pump.2. The device as recited in wherein the filling level sensor is an ultrasonic sensor.3. The device as recited in wherein the filling level sensor includes at least one floating gauge.4. A method for ascertaining the tank filling level claim 1 , comprising the following steps:ascertaining a state space system;then ascertaining a tank volume value with the aid of a Kalman filter;ascertaining a tank filling level value; andsubsequent filtering of the tank filling level sensor value. This claims the benefit of German Patent Application DE 10 2011 122 127.5, filed Dec. 22, 2011 and hereby incorporated by reference herein.The present invention relates to a method and a device for detecting the tank filling level in a motor vehicle.Such approaches work by detecting an analog signal of a tank filling level sensor. The signal is sharply filtered through algorithms implemented in a control unit in order to reduce the sloshing in the signal caused by driving. Since the characteristic constant of the low-pass filter must be large, the low-pass filter becomes slower. The filtered signal will not indicate the prevailing filling level but instead will indicate a previous filling level. This is noticeable in particular when the liquid is being pumped out of the tank, as in the case of a fuel tank or an ADBLUE (a trademark as described below, also known as a diesel exhaust fluid or AUS 32) tank.In addition, there are complex methods which attempt to increase the reliability of the low-pass filter result by taking into account the vehicle state ( ...

MAGNETOSTRICTIVE PROBE WITH INVERTED SIGNAL DETECTION

Номер: US20140224010A1
Автор: Prinstil Ambroise
Принадлежит:

The present discloses an alternate construction and method for a magnetostrictive probe intended to be used as a tank monitoring device. Height determination, either water or fuel, is referenced to an ultrasonic pickup assembly located inside the shaft at the foot of the probe. With this inverse approach, height measurement takes advantage of the relative geothermal stability of underground storage tanks, or the temperature stability offered by the thermal mass of the fuel, to facilitate a more accurate tank level determination. At that new location, the detection circuit gains the added benefits of being isolated from the effect of magnetic risers, large temperature swings and other undesirable phenomenon that often affect magnetostrictive probe measurements that are referenced to the canister. Aside from its primary use as referred to by this disclosure, this probe could be adapted for any application necessitating precise knowledge of height or distance measurement in relation to the foot of the probe without using a reference magnet. 1. A magnetostrictive probe adapted to monitor liquid level comprising:An ultrasonic pulse signal detection assembly apparatus situated at the foot of the probe,a wire tensioning assembly system located in line with the waveguide inside the canister located at the top of the probe,a bottom compression assembly located inside the tube,a sealed tube containing a ferromagnetic wire which is placed vertically in the liquid container so as to approximately reach the bottom of said container, and extend above the fill level of said container,a float for each type of liquid to be measured, whether one liquid or two or more liquids which are separated due to density differences,a magnet in each of said float(s) which interacts with magnetic fields generated in said magnetostrictive wire by current pulses so as to generate ultrasonic waves that travel in both directions along said wire,a circuit which convers said wire signal to digital ...
