Detailed Description

The following describes the technical scheme of the present invention in detail with reference to the accompanying drawings.

Referring to FIG. 1, a flow chart of a vehicle fueling monitoring method of the present invention is shown. As can be seen from fig. 1, after the method starts, the fuel level in the tank is monitored to determine whether the variation in the fuel level rise exceeds a preset value. In general, a liquid level sensor is provided in a fuel tank of a vehicle to detect a liquid level in the fuel tank, and fuel level information in the fuel tank detected by the liquid level sensor is displayed in an instrument panel of the vehicle. Therefore, the vehicle fuel filling monitoring method can acquire the liquid level information in the oil tank by utilizing the existing liquid level sensor in the vehicle.

When the vehicle is being fueled, the fuel level in the tank will rise. Therefore, in the above-described steps, the present invention determines whether the vehicle is completed or is being filled with fuel by determining whether the fuel level rise height variation value exceeds the preset value. The amount of oil charged by each driver varies from one consideration to another at each fueling. In some cases the driver may be topped up, which may lead to a greater rise in the fuel level in the tank in case the fuel level in the tank is low; there are situations where the driver does not fill too much fuel, for example for a passenger car driver it may only fill a certain amount of fuel, in which case the fuel level rises relatively little. Thus, the preset value in the present invention refers to a variation in the level of the fuel in the fuel tank, that is, a difference of the raised fuel level minus the fuel level before the raising. Specific setting can be carried out on the preset value aiming at the oil tanks with different sizes, so long as the preset value can reflect that the fuel oil filling with a certain volume or a certain amount is carried out. For example, the preset value may be a fuel level increase value in the case of fuel filled with 50 yuan of civil coins.

Specifically, when the fuel level in the fuel tank is H1 at time t1 and the fuel level in the fuel tank is H2 at a certain time t2, it is determined that the vehicle is filled with fuel when H2> H1 and H2-H1 >. DELTA.h.

When the change of the elevation of the fuel level is detected to exceed the preset value, the vehicle is considered to be filled with fuel. At this time, the current position information of the vehicle is recorded. The current position information may be acquired using a positioning device of the car navigation device.

According to the method, whether the vehicle is fuelled or not can be confirmed, and the geographic position of the vehicle where the vehicle is fuelled can be known.

Based on the above information, the present invention proposes various applications, so that the fuel quality of a vehicle can be improved.

For example, FIG. 2 shows a flow chart of another embodiment of a vehicle fueling monitoring method of the present invention. As can be seen from fig. 2, when the current position information is recorded, a judgment can be continued, and the recorded current position is compared with the pre-stored position to confirm whether the current position is included in the pre-stored position. The "pre-stored location" is a collection of locations, which may be a white list, containing geographical location information of fuel stations that are up to standard. The "pre-stored location" may be updated, for example, a reliable brand of gas station is newly created somewhere, the geographical location of the gas station may be added to the white list, or, based on a report issued by the quality supervision department, a gas station is checked for a fuel quality failure, and the location information of the gas station may be removed from the white list.

If the current position is not included in the pre-stored position, the current position information and the liquid level change information are marked. The marked records can be sent to the cloud end in real time, at fixed time nodes or at certain time intervals, so that a manager of the vehicle can monitor the fuel filling condition of the vehicle in time. Of course, the marked records may also be stored locally and the relevant personnel may read them at the appropriate time.

Thus, according to the embodiment of fig. 1, the present invention records each time the vehicle is filled with fuel. In this case, the amount of recorded data is large. However, it is considered that under normal conditions, filling up the fuel with quality-meeting fuel has no effect on the vehicle, so that analysis of these recordings is not necessary. For this reason, the preferred embodiment of FIG. 2 can make further determinations of these records, identifying fuel fill records that are likely to be up to quality, which can enable fuel fill events that are up to quality to be highlighted, and also reduce the amount of data sent when data is sent.

The method shown in fig. 2 is particularly suitable for the management of commercial vehicles. Under the current use environment of China, a commercial vehicle belongs to a production tool, when a vehicle owner or a driver refuels, the vehicle owner or the driver can refuel to a non-normal gas station due to the consideration of cost saving, but the fuel quality of the gas station is not guaranteed, so that the vehicle is likely to fill with fuel with the fuel quality which does not reach the standard, thereby influencing the performance of an engine and the performance and the service life of a post-treatment device, and causing the exhaust emission to exceed the standard, so that the atmospheric pollution is caused.

After the method of fig. 2 is adopted, the manager can timely find that the vehicle is filled with fuel at the unauthorized filling station, so that corresponding measures are taken, for example, a vehicle user can be reminded to fill fuel at the allowed filling station, the fuel is prevented from being filled at the unauthorized filling station, and the basis can be provided for future conditions such as whole vehicle use and failure of the post-processing device.

Of course, the method shown in fig. 2 can also be advantageously applied in a car rental company. On various types of taxi platforms or rental platforms, the user of the vehicle is more concerned with the cost of fueling, and is not concerned with the adverse effects of fuel quality on the vehicle. Therefore, after the method of the invention is used, the behavior of filling the fuel oil with unqualified quality can be found in time, or the basis is provided for the reasons such as the failure and the failure of the vehicle.

Fig. 3 shows a variant of fig. 2. In the variant shown in fig. 3, the "pre-stored locations" are a set of locations: the geographical position information of the gas station with the unqualified fuel quality is contained. That is, the set of locations is a blacklist. Likewise, the "pre-stored location" may be updated, for example, if a gas station is checked for fuel quality based on reports issued by quality supervision authorities, and the location information of the gas station may be added to the blacklist.

Accordingly, when the current position is included in the pre-stored position, the current position and the liquid level change information may be marked as information associated with each other.

Of course, as a further improvement of the method of the present invention, the present invention can also add other conditions to serve as the basis for identifying and marking all of the fuel filling records recorded in fig. 1. For example, instead of identifying and marking the fueling location after the fueling event is recorded as in fig. 2 and 3, as in fig. 4, the fueling event recorded is analyzed after the vehicle has failed in relation to fuel quality without identifying the fueling event, to determine whether the vehicle has been fueling at an unauthorized fueling station, thereby providing a basis for possible failure of the engine and aftertreatment devices associated with fuel quality that may occur in the vehicle. The engine and aftertreatment device malfunctions that may be related to fuel quality are, for example, the ignition of a related malfunction lamp on the vehicle, or the malfunction of a three-way catalyst, for example. The method of the present invention may be implemented on a variety of hardware. The method of the invention can be implemented by utilizing the existing sensors of the vehicle, such as a liquid level sensor for detecting the liquid level of the fuel in the fuel tank, a position sensor for determining the geographical position of the vehicle, and the position information of the vehicle. The information CAN be transmitted to a component having a controller, such as a vehicle machine, via a vehicle communication line, such as a CAN bus, or the like.

As a preferred embodiment of the present invention, a nitrogen oxide sensor provided on a vehicle may be employed as a hardware carrier. Specifically, the nox sensor is provided with a controller and CAN be connected to the CAN bus of the vehicle, so that corresponding information CAN be acquired from the CAN bus and recorded. When the vehicle has faults related to the engine and the after-treatment device, the related information can be read from the nitrogen oxide sensor, so that basis is provided for fault analysis.

Therefore, the method can be implemented by utilizing the existing hardware on the vehicle, the fuel filling condition of the vehicle can be monitored without adding new hardware, and whether the fuel filling is carried out at a gas station with the fuel not reaching the standard can be judged according to the pre-stored information, so that an analysis basis is provided for any fault possibly occurring in the follow-up.

While the present invention has been described with respect to the above exemplary embodiments, it will be apparent to those skilled in the art that various other embodiments can be devised by modifying the disclosed embodiments without departing from the spirit and scope of the invention. Such embodiments should be understood to fall within the scope of the invention as determined based on the claims and any equivalents thereof.
