In a first aspect, a method for determining a float fault of a liquid level sensor according to an embodiment of the present invention includes:

detecting a first consumption volume of urea at a urea nozzle in the fault judgment period;

detecting a first urea volume and a second urea volume in a urea box through a liquid level sensor arranged in the urea box, and taking a difference value between the first urea volume and the second urea volume as a second consumption volume of urea in the urea box in the fault judgment period; the first urea volume is the volume of urea in the urea box at the starting moment of the fault judgment period; the second urea volume is the volume of urea in the urea box at the end of the fault judgment period;

and if the vehicle has urea addition in the fault judgment period, stopping detecting the first consumption volume of urea at the urea nozzle in the fault judgment period, and taking the time when the vehicle urea addition is finished as the starting time of the next fault judgment period.

In one possible implementation, before determining a float fault of a level sensor of the urea tank, the method further comprises:

determining that a part of the level sensor other than the float part is not malfunctioning, and/or

It is determined that the urea nozzle is not malfunctioning.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

The application scenario described in the embodiment of the present invention is for more clearly illustrating the technical solution of the embodiment of the present invention, and does not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by a person skilled in the art that with the occurrence of a new application scenario, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems.

Some of the words that appear in the text are explained below:

1. the term "electronic device" in the embodiments of the present invention refers to any device capable of automatically processing a large amount of data at a high speed according to a program, and includes a mobile phone, a mobile robot, a computer, a tablet, an intelligent terminal, a multimedia device, a streaming media device, and the like.

2. And the liquid level sensor detects the volume of urea in the urea box through the change of the resistance value caused by the up-and-down floating of the floater. Referring to FIG. 1, a schematic view of a float of a fluid level sensor is shown.

In the prior art, whether the floater of the liquid level sensor breaks down or not can be detected only in a detachable mode, and the failure judgment mode is troublesome.

The following describes a float failure determination method of a liquid level sensor in detail with reference to the accompanying drawings.

Referring to fig. 2, an embodiment of the present invention provides a method for determining a float fault of a liquid level sensor, including:

s200: detecting a first consumption volume of urea at a urea nozzle in the fault judgment period;

the total mass of the urea consumed by the urea nozzle at the moment when the vehicle starts to run is recorded, so in the embodiment of the invention, the total volume of the urea consumed by the urea nozzle before the starting moment of the fault judgment period is recorded, namely the total mass of the urea consumed by the urea nozzle is divided by the urea density, then the total mass of the urea consumed by the urea nozzle at the moment when the fault judgment period is ended is obtained, and then the total mass of the urea consumed by the urea nozzle at the moment when the fault judgment period is ended is divided by the urea density to obtain the total volume of the urea consumed by the urea nozzle at the moment when the fault judgment period is ended;

and adopting the obtained total volume of the urea consumed at the urea nozzle at the moment when the fault judgment period is ended, recording the total volume of the urea consumed at the urea nozzle before the moment when the fault judgment period is started, and taking the difference value between the two total volumes as the first consumption volume of the urea at the urea nozzle in the fault judgment period.

Since the end of the present failure determination period is also the start of the next failure determination period, the total volume of urea consumed at the urea nozzles recorded at the end of the present failure determination period is recorded as the total volume of urea consumed at the urea nozzles at the start of the next failure determination period. And so on.

S201: detecting a first urea volume and a second urea volume in the urea box through a liquid level sensor arranged in the urea box, and taking a difference value between the first urea volume and the second urea volume as a second consumption volume of urea in the urea box in the fault judgment period;

the first urea volume is the volume of urea in the urea box at the starting moment of the fault judgment period; the second urea volume is the volume of urea in the urea box at the end of the fault judgment period;

as described above, at the start time of the fault determination period, the liquid level sensor changes the resistance value due to the up-and-down floating of the float, and detects the first urea volume in the urea tank; at the end of the fault judgment period, the liquid level sensor changes the resistance value due to the up-and-down floating of the floater, and the volume of second urea in the urea box is detected; thereby taking the difference between the first urea volume and the second urea volume as the second depleted volume.

S202: and if the difference value between the first consumption volume and the second consumption volume is larger than a preset value, determining that the floater of the liquid level sensor of the urea tank is in fault.

If the floater of the liquid level sensor of the urea tank is not in fault, the urea consumption in the fault judgment period is the same as that in the fault judgment period detected by the liquid level sensor, of course, if the error detected by the liquid level sensor and the error detected by the nozzle are taken into consideration, the urea consumption is similar, and if the two consumptions are large in volume and larger than a preset value, the floater of the liquid level sensor of the urea tank is determined to be in fault. Therefore, the invention can detect whether the floater has faults without disassembling the liquid level sensor, thereby simplifying the fault judgment mode.

Further, due to the error detected by the liquid level sensor and the error detected by the nozzle, if the consumed volume in the fault judgment period is small, the judgment is likely to be wrong due to the error, for example, if 0.1 liter is consumed and the error is 0.05 liter, the judgment is likely to be inaccurate due to the fact that the error is close to the consumed volume. Based on the above, the present invention proposes that the difference between the total volume of urea consumed by the urea nozzle before the start time of the current fault determination cycle and the total volume of urea consumed by the urea nozzle before the end of the current fault determination cycle exceeds a preset volume.

That is, the subsequent determination process is started only when the first consumption volume of urea at the urea nozzle in the fault determination period is larger than the preset volume.

Since the urea volume in the urea tank increases with the addition of urea, the detection of the urea volume in the urea tank in the current fault detection cycle is inaccurate, and the result of the detection is the addition of the consumed portion and the added portion. Based on this, the present invention determines that the vehicle is not adding urea during the present fault determination period before detecting the first depleted volume of urea at the urea nozzle during the present fault determination period. And if the vehicle has urea addition in the fault judgment period, stopping detecting the first consumption volume of urea at the urea nozzle in the fault judgment period, and taking the time when the vehicle urea addition is finished as the starting time of the next fault judgment period.

When the vehicle has urea addition in the fault judgment period, the total urea consumption mass injected from the urea nozzle at the time of finishing the vehicle urea addition is divided by the urea density, the obtained total urea volume is recorded as the total urea consumption volume before the starting time of the next fault judgment period, and the time of finishing the vehicle urea addition is used as the starting time of the next fault judgment period. And detecting in the next period, wherein the influence of the urea addition is not received in the next fault judgment period, and the difference value between the first urea volume and the second urea volume in the urea box is detected by a liquid level sensor arranged in the urea box to be not influenced by the urea addition.

In order to be able to determine more reliably whether the result of a malfunction of the float of the level sensor of the urea tank is more certain, other malfunctioning places are excluded, for example, it is determined that other parts of the level sensor than the float part are not malfunctioning, and/or it is determined that the urea nozzle is not malfunctioning. And when the difference value between the first consumption volume and the second consumption volume is larger than a preset value, determining that the float of the liquid level sensor of the urea tank is in fault.

The embodiment of the invention also provides a mode, and after the float fault of the liquid level sensor of the urea box is determined, the float fault of the liquid level sensor of the urea box is informed to a user, so that the fault point can be accurately positioned, manual repair is carried out, and the overhaul efficiency is improved.

In conjunction with the above-described process, an embodiment of the present invention provides a complete method for determining a float fault of a liquid level sensor, which is shown in conjunction with fig. 3, and includes:

s300: determining that other parts except the floater part in the liquid level sensor are not in fault, determining that a urea nozzle is not in fault, and determining that the vehicle is in a urea injection stage;

s301: determining the total volume of urea consumed by the vehicle through the urea nozzle according to the total mass of urea consumed by the vehicle through the urea nozzle and the urea density;

s302: judging whether urea is added or not; if so, executing S303; otherwise, executing S304;

s303: calculating a difference value between the total volume of the urea consumed by the vehicle at the urea nozzle and the total volume of the urea consumed by the vehicle at the urea nozzle at the starting moment of the fault judgment period, and taking the difference value as a first consumption volume;

s304: taking the total volume of the urea consumed by the vehicle through the urea nozzle as the total volume of the urea consumed by the vehicle through the urea nozzle at the starting moment of the next fault judgment period;

s305: judging whether the first consumption volume is not less than a preset volume; if so, executing S306; otherwise, executing S301;

s306: detecting a first urea volume and a second urea volume in the urea box through a liquid level sensor arranged in the urea box, and taking a difference value between the first urea volume and the second urea volume as a second consumption volume of urea in the urea box in the fault judgment period;

s307: judging whether the difference value between the first consumption volume and the second consumption volume is larger than a preset value, if so, executing S308, otherwise, executing S309;

s308: determining the float fault of a liquid level sensor of the urea box, and informing a user of the float fault of the liquid level sensor of the urea box;

s309: it is determined that a float of a level sensor of the urea tank is not malfunctioning.

In conjunction with the above-described process, the embodiment of the present invention provides a complete method for determining a float fault of a liquid level sensor, which is shown in conjunction with fig. 4:

and acquiring the total mass of the urea consumed at the current urea nozzle, inputting the total mass into a position UDC _ mRdcAGDosQnt, dividing the total mass by the urea density input through a position UDC _ rhoRdcAg _ C to obtain the total volume of the urea consumed at the current urea nozzle, wherein the total volume is more than or equal to the preset volume input through a position (3) and the total volume of the urea consumed at the previous urea nozzle recorded at the starting moment of the fault judgment period, and inputting the difference value between the total volume of the urea consumed at the current urea nozzle and the total volume of the urea consumed at the previous urea nozzle recorded at the starting moment of the fault judgment period, namely the first consumption volume into a position (7). The total volume of urea consumed by the urea nozzle before the start of the fault determination cycle is stored in advance, and the control gate switch P1 is operated to store the current total volume of urea consumed by the urea nozzle as the total volume of urea consumed by the urea nozzle before the start of the fault determination cycle.

If urea addition is input at position (4), the input of the first consumption volume to position (7) is stopped, and the control door switch P1 is actuated to store the current total volume of urea consumed at the urea nozzle as the total volume of urea consumed at the urea nozzle before the time when the next failure determination cycle is started.

The volume in the urea tank is detected by a liquid level sensor installed in the urea tank at the end of the last fault determination period as a first urea volume of urea in the urea tank at the start of the current fault determination period.

When the control door switch p1 is actuated, if urea addition is input at position (4), the volume in the urea tank is detected by a level sensor attached to the urea tank as the first urea volume of urea in the urea tank at the start of the next failure determination period.

When the control door switch p1 is actuated, if urea addition is not input at position (4), indicating that urea is not added to the urea tank in the current failure determination cycle, the volume of urea in the urea tank at the end of the current failure determination cycle is set as the first urea volume of urea in the urea tank at the start of the next failure determination cycle.

A first volume of urea in the urea tank at the start time of the fault judgment cycle is input at a position (5), a second volume of urea in the urea tank detected by a liquid level sensor arranged in the urea tank is input at the position UDC _ volRdcAGrmn, and the difference value of the two urea volumes is obtained as a second consumption volume.

The first depleted volume and said second depleted volume are compared in size, and if the difference between the first depleted volume and said second depleted volume is greater than a preset value, the door switch P2 is controlled so that DSM _ FAULT _ period _100 inputs a signal to DSM _ DebTUD informing the DSM _ DebTUD of a float FAULT of the level sensor of the urea tank. If the difference between the first depleted volume and the second depleted volume is not greater than the predetermined value, then DSM _ FAULT _ PERCENTT _00 inputs a signal to DSM _ DebTUD informing the DSM _ DebTUD that the float of the level sensor of the urea tank is not malfunctioning.
