Definitions
- the invention relates to a method and a device according to the preamble of claim 1 and claim 11, respectively.
- a measuring device for operating fluid supplies of motor vehicles is known, which is provided with a fuel system, which has a main storage container and a secondary storage container, which has a significantly smaller volume compared to the main storage container and is self-contained and is fueled by a pump from the main reservoir.
- a main sensor device or an auxiliary sensor device for determining the fuel supply is assigned to the main storage tank and the secondary storage tank.
- the main sensor device assigned to the main storage container supplies a signal which indicates the fill level in the fuel tank, so that a quantity value can be calculated from the tank geometry, which leads to a display which leads to the display indicates the total amount of fuel present in the main storage tank and secondary storage tank.
- the fuel remaining in the secondary reservoir is displayed by the auxiliary sensor device assigned to the latter. This is supposed to give a more accurate display of the existing fuel reserve can be achieved.
- a tank display and a method for determining the remaining volume in a tank which has a surge tank there called a reservoir and an additional tank from which the fuel can be emptied in the latter when a certain low level in the main tank is reached.
- the respective remaining volume of fuel, which comes from the additional tank is calculated on the basis of fuel consumption values. In this way, it may be possible to determine the residual amount of fuel still present in the tank with sufficient accuracy.
- this is purchased with a considerable additional outlay, since the main tank must be provided with an additional tank which is connected to the reservoir or surge pot via a line which can be closed by a valve.
- DE 38 25 630 AI discloses a method for determining and displaying the quantity of fuel contained in a storage container, in which a static transmitter is provided which supplies the initial value for the display.
- the consumption values accumulating during the operation of a motor vehicle are calculated by consumption measurements or the evaluation of consumption-determining engine characteristic values and subtracted from this initial value. The resulting difference is displayed.
- the accuracy of the display of the remaining amount in each case also depends on the accuracy in the reserve area, ie if there is only a little fuel left in the tank, with which the total initial volume is initially determined by the transmitter, which is responsible for the level fluctuations in the Supply quantity contains undamped measuring float, whereby the initial value of the supply quantity can also be replaced by an average value which is formed from sensor output signals recorded at larger time intervals.
- DE 38 25 630 AI does not disclose any details regarding the design of the tank and the definition of a certain amount of fuel, which still has a reserve amount for a largely empty tank forms a certain route.
- the invention is based on a method and a device for determining the amount of fuel in each case in the fuel tank of a motor vehicle according to the preamble of claim 1 and that of claim 11, the respective preamble taking into account the prior art according to DE 196 10 154 AI.
- a method is particularly expedient in which the point in time at which the determination of the remaining amount in the reservoir by the consumption calculation begins is determined as a function of the filling state in the main storage container and of a specific filling level in the reservoir, for example in such a way that a filling level meter assigned to the main storage container generates a signal emits, which means that the main reservoir is empty, and in addition a signal is triggered by a sensor assigned to the reservoir when the level falls below the certain level in the reservoir.
- the sensor is expediently arranged below the maximum fill level of the reservoir, so that the consumption calculation only then begins when the liquid level in the reservoir is at a distance from its upper limit, so that surge movements of the liquid have a less pronounced effect due to the driving dynamics.
- the sensor in the reservoir is not assigned the maximum possible fill level in it, that the residual quantity calculation is first switched on and then switched off again when the main container is almost empty, e.g. B. Depending on the driving condition, small amounts of fuel are still pumped into the reservoir so that the fill level reaches the sensor again.
- the arrangement of the sensor in the reservoir should therefore be chosen so that under normal operating conditions no more fuel from the main reservoir into the reservoir is promoted after the level determined by the position of the sensor in the reservoir has fallen below and the calculation of the fuel consumption to determine the remaining fuel quantity has been triggered.
- the reservoir can also be expedient to provide the reservoir with internals which largely reduce the movements of the fuel in the reservoir. If the beginning of the time at which the determination of the respective remaining quantity by the calculation of the fuel consumption begins is determined depending on the presence of two signals - one that indicates that the main reservoir is essentially empty and a later, second signal, which indicates the fill level of the reservoir - the amount of liquid still available at the start of the consumption calculation can be determined with an accuracy that is sufficient for all practical requirements.
- a fill pipe can be provided, which connects the fill opening of the tank to the reservoir. If in the operating phase in which the remaining fuel in the reservoir is determined by consumption measurement, fuel z. B. is refilled from a reserve canister in an amount that is not sufficient to fill the reservoir up to the level corresponding to the position of the sensor, a correction of the determination of the remaining fuel quantity would not be possible. Rather, the display of the remaining fuel quantity would remain at the value calculated before the refill. It can therefore be expedient to assign a second sensor to the reservoir, which is positioned at a distance below the first sensor and thus responds to a smaller fuel volume in the reservoir.
- the signal triggered thereby can be used to calculate the determination of the remaining fuel quantity in the reservoir again based on the consumption, which of course then starts with an initial value. which is smaller than that of the volume which corresponds to the position of the first sensor.
- the second sensor is expediently arranged in such a way that, after the refilling of fuel from a reserve canister with the usual volume (for example 5 1), the second sensor is below the liquid level which then arises.
- the driver Before switching off the engine automatically, the driver should be warned of the fact that the engine will soon be switched off by a suitable display.
- the arrangement is such that the level meter assigned to the main reservoir is reactivated as soon as it increases with increasing fuel.
- the mirror in the main storage tank switches from the empty display to the display of a certain liquid level in the main storage tank.
- the signal can also influence the on-board computer or the like at the same time so that the calculation of the fuel consumption is ended.
- the computer is only reactivated for this calculation when the conditions mentioned above again occur in the course of driving, namely empty display for the main storage container and falling below the fill level in the reservoir, which is determined by the position of the first sensor.
- Fig. 1 shows a longitudinal section through a first embodiment of a tank
- Fig. 2 shows a longitudinal section through a second embodiment.
- the fuel tank 10 can be made in one or more parts from plastic or metal in different ways. It is provided with a residual quantity container or reservoir 12, which has a noticeably smaller volume than the main space 34 surrounding the reservoir 12 and represents the reserve area of the fuel system. This reservoir 12 is suitably attached to the bottom 14 of the tank.
- the reservoir is provided with an inner peripheral edge 62 at its upper end, so that there is only one overflow opening 64. Otherwise, the reservoir is closed in itself so that no fuel can escape from the reservoir into the main reservoir 34.
- the bottom 18 of the reservoir 12 is provided with a central region 20 which runs essentially vertically to the longitudinal axis of the reservoir and parallel to the bottom of the tank 14.
- the outer region 22 of the base 18 adjoining the central region 20 rises towards the periphery of the reservoir arranged so that this outer region 18, starting from the central region 20, has an increasing distance from the bottom 14 of the tank in the direction of the circumference.
- it is provided on the underside in the outer bottom area with essentially radial ribs 24, which are arranged at intervals around the circumference of the reservoir and rest on the bottom 14 of the tank .
- a single-stage electric fuel pump 26 is attached, to which a line 28 leading to the engine is connected, into which a pressure regulator 30 is switched on in the tank 10 in a known manner, one of which Return line 32 goes out.
- the excess fuel quantity is branched off in the pressure regulator 30 and is returned through the return line 32 located outside the reservoir 12 into the space 34 of the tank 10 surrounding the reservoir 12.
- the return line 32 is provided with the drive nozzle 36 of a suction jet pump 38, the catch nozzle 40 of which forms the inflow end of an overflow pipe 42, as shown in the drawing.
- the overflow pipe is arranged to run essentially vertically and opens out at a short distance from the upper boundary of the reservoir 12 and is guided in a liquid-tight manner through the outer region 22 of the base, the design of which accommodates the suction jet pump 38 in the region below the reservoir 12 enables.
- the tank 16 is provided in its top wall 16 with an opening 44 which is closed by a cover 48 with the interposition of a seal 46.
- the fuel line 28 leading to the engine as well as electrical lines 50 for the energy supply of the pump 26 and electrical connection lines 52 and 54 are passed through this cover 48 in a liquid-tight manner.
- the line 52 is used to connect a capacitive or otherwise designed filling level meter 56 and an electronic computer 57, which may be the vehicle's on-board computer.
- the line 54 establishes the connection between a first sensor 59 and / or a second sensor 68 in the reservoir 12 and the computer.
- the fill level meter 56 is arranged in the main space 34 of the tank 10 surrounding the reservoir 12, the first sensor 59 and the second sensor 68 are arranged inside the reservoir 12 in a dip tube 58.
- the fuel to be supplied to the engine is withdrawn from the reservoir 12, the fuel conveyed from the main chamber 34 of the tank into the reservoir via the suction jet pump 38 always keeping the level within the reservoir 12 at a maximum level, as long as fuel is still out of the chamber 34. is promoted.
- the level determination in the tank 10 takes place as long as fuel is still present in the main space 34 surrounding the reservoir 12, via the level meter 56, which in the usual way, for. B. can also be designed as a float sensor. However, other level meters can also be used. Up to the more or less complete emptying of the space 34 surrounding the reservoir 12, the fill level meter 56 supplies the signals indicating the fill level of the space 34, from which the respective amount of fuel still present is determined.
- the electronic computer 57 is signaled.
- This signal means that the fuel still present in the system, which is practically exclusively in the reservoir 12 is present, and the volume of which is determined, the consumption is calculated and the display shows the amount of fuel still present from the difference between a defined volume of the reservoir and the consumption that occurred up to the time the signal was received.
- the consumption is easily determined from the operating data available for the engine control system. tion can be determined by the computer.
- the first sensor 59 is located at a relatively short distance below the upper limit of the reservoir 12. It can also be used - if necessary alternatively - to trigger the signal by which the remaining fuel quantity in the reservoir is determined by the fuel consumption of the Motors is calculated.
- the volume of which, together with the residual volume still present in the reservoir 12 is smaller than the total volume of the reservoir and thus leads to a fill level whose liquid level is below the level of the sensor 59 is to let a consumption calculation start again when the sensor 68 falls below, which of course then starts from an initial value that is smaller than the value that corresponds to the position of the sensor 59.
- the replenished amount would first get into the main storage container 34, but from this would be largely conveyed back into the reservoir 12 by the suction jet pump 38 until the main storage container is empty again, so that it is independent in which part of the tank the refilled quantity initially flows, but does get into the reservoir and causes an increase in the liquid level.
- the tank 10 Since the tank 10 is refueled through the filler pipe 74, which in the area of the nozzle 76 can rest against its inner boundary wall in a liquid-tight manner, the entire amount of fuel filled into the tank initially flows into the reservoir 12, so that even when a small amount of fuel is filled the liquid level in the reservoir 12 rises immediately and it is then only a question of the positioning, in particular of the lower sensor 68, when, that is to say the amount of fuel which responds. In any case, it is ensured that fuel supplied to the tank 10 from the outside first enters the reservoir 12 and, if necessary, overflows from there through the upper opening 64 into the main storage container 34.
- the arrangement of the sensor 59 at a distance from the upper end of the riser pipe 58 or the upper limit of the reservoir 12 enables a more precise determination of the amount of fuel present in the reservoir 12 at the time when the measurement of the fuel consumption begins, since inaccuracies largely result from fuel spilling out of the reservoir be avoided.
- a two-stage electric fuel pump can also be used, the bottom of the reservoir 12 being provided with a passage for the fuel to be drawn in from the space 34 surrounding the reservoir 12 and the arrangement must be such that when the space 24 is empty, no fuel from the reservoir 12 in the room 34 flows back through this opening.
- appropriate measures would have to be taken to ensure that the first stage of the two-stage fuel pump does not become too warm due to a lack of cooling due to fuel flowing in from the space 24 when the space 24 is empty.
- the switch back to the normal measurement of the amount of fuel in the system can be effected by the fill level meter 56 assigned to the space 34 the next time the tank is filled by a signal triggered by this fill level meter, by which the computer 57 is triggered, to the normal one Switch back operation for measuring the amount of fuel in the tank system.
