[0002] A flexible-fuel vehicle is a vehicle equipped with a flexible-fuel engine (engine). A flexible-fuel vehicle can use two or more fuels (such as gasoline, methanol, ethanol, etc.) mixed in any proportion.

[0003] For flexible fuel vehicles, it is relatively difficult to calculate the driving range. For example, a traditional single-fuel vehicle uses a single fuel, so the driving range can be calculated based on energy consumption and the amount of fuel in the fuel tank. Different fuels in hybrid vehicles are added to different fuel tanks, so the driving range can also be calculated in a similar way to the calculation of the driving range in traditional single-fuel vehicles. However, different types of fuels in flexible fuel vehicles are added to the same fuel tank. For example, after refueling, the proportion of different fuels in the fuel tank cannot be determined, and the energy consumption of different fuels is usually different, so it is impossible to determine an accurate and reliable driving range through the above method. Summary of the invention

[0023] If the total energy consumption of the vehicle is greater than the energy consumption comparison value of the vehicle, the current energy consumption value of each fuel is adjusted upward, otherwise, the current energy consumption value of each fuel is adjusted downward.

[0045] The present application is further described in detail below in conjunction with the embodiments and drawings. It is to be understood that the specific embodiments described herein are only used to explain the relevant application, rather than to limit the application. It is also necessary to explain that, for ease of description, only the parts related to the application are shown in the drawings.

[0046] It should be noted that, in the absence of conflict, the embodiments of the present application, that is, the features of the embodiments, can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] The following describes in detail a method, system and vehicle for calculating the driving range of a flexible fuel vehicle according to an embodiment of the present application in conjunction with the accompanying drawings.

[0048] Before describing the cruising range calculation method, system and vehicle of a flexible-fuel vehicle according to an embodiment of the present application, the flexible-fuel vehicle is first explained. A flexible-fuel vehicle is a vehicle equipped with a flexible-fuel engine (engine). A flexible-fuel vehicle is a vehicle that can use two or more fuels (such as gasoline, methanol, ethanol, etc.) mixed in any proportion. These two or more fuels do not need to be added to different fuel tanks (fuel containers) separately, but are added to the same fuel tank of the vehicle and mixed in the fuel tank, that is, the mixed fuel is in the same fuel tank.

[0049] Figure 1 FIG. 1 is a flow chart of a method for calculating the driving range of a flexible fuel vehicle according to an embodiment of the present application. Figure 1As shown, according to an embodiment of the present application, a method for calculating the driving range of a flexible fuel vehicle includes the following steps:

[0050] S101: Obtain the total amount of fuel in a fuel tank of a vehicle and the fuel proportion of each fuel in the fuel tank.

[0051] In one embodiment of the present application, the total amount of fuel in a fuel tank of a vehicle is obtained, including: obtaining a fuel level value in the fuel tank, and filtering the fuel level value to obtain the fuel level filter value; and obtaining a fuel volume according to the fuel level filter value, wherein the fuel volume represents the total amount of fuel.

[0052] The total amount of fuel in the fuel tank can be detected during or after refueling of the vehicle or while the vehicle is driving, by detecting the fuel level value in the fuel tank through a level sensor in the fuel tank, and then calculating the fuel volume in the fuel tank based on the fuel level value in the fuel tank.

[0053] For example, after the vehicle is refueled, refueling the fuel tank means replenishing the vehicle, that is, any fuel supported by the vehicle can be refueled into the vehicle's fuel tank. When any fuel is added to the fuel tank, the proportion of various fuels in the fuel tank will change. Therefore, by detecting the liquid level of the fuel tank, the total amount of fuel in the fuel tank after refueling can be obtained.

[0054] Specifically, the fuel tank has a liquid level sensor for detecting the liquid level. The liquid level sensor detects changes in the liquid level of the fuel in the fuel tank, and thus the liquid level value can be obtained. Moreover, since the total capacity of the fuel tank is known, for example, the total capacity of the fuel tank is 60 liters, and the current liquid level value occupies 3 / 4 of the height within the total capacity, the fuel volume of the fuel in the fuel tank after refueling can be converted based on the total capacity of 60 liters and the current liquid level value occupying 3 / 4 of the height within the total capacity, such as 3 / 4 of 60 liters is 45 liters.

[0055] The accuracy of the fuel volume in the fuel tank will affect the accuracy of the cruising range calculation. Therefore, before obtaining the fuel volume based on the fuel level value, the fuel level value is filtered. That is, the purpose of filtering is to reduce or even eliminate the error in the detection of the fuel level value, so that the calculation result of the fuel volume is more accurate. For example, when the vehicle is refueling, it is on a sloped ground. In this way, after the fuel level is obtained according to the detection of the level sensor in the fuel tank, it is filtered to avoid the influence of the slope causing the final fuel volume calculation to be too large. That is, the error in the fuel level detection caused by the slope is eliminated, thereby ensuring that the calculation result of the fuel volume is more accurate and reliable.

[0056] In one embodiment of the present application, the fuel ratio of each fuel in the fuel tank of the vehicle can be detected by a fuel sensor disposed in the fuel tank. The fuel sensor in the fuel tank is used to detect the fuel ratio of each fuel in the fuel tank. For example, there are three fuels in the fuel tank, namely gasoline, methanol, and ethanol. Assuming that after adding gasoline, the fuel sensor detects that the gasoline ratio (i.e., the fuel ratio of gasoline) in the fuel tank is 70%, the methanol ratio (i.e., the fuel ratio of methanol) is 20%, and the ethanol ratio (i.e., the fuel ratio of ethanol) is 10%. For another example, assuming that there are two fuels in the fuel tank, denoted as the first fuel and the second fuel, the fuel sensor detects that the fuel ratio of the first fuel is 70%, and the fuel ratio of the second fuel is 30%.

[0057] In this example, the first fuel is gasoline, for example, and the second fuel is methanol, for example.

[0058] S102: Obtain the current energy consumption value of each fuel.

[0059] It should be noted that the initial energy consumption value of each fuel in the vehicle can be obtained through a cruising range test, for example: using the NEDC (New European Driving Cycle) cruising range standard to conduct a cruising range test to obtain the initial energy consumption value of each fuel, or using the CLTC (China Light-duty Vehicle Test Cycle) cruising range standard to conduct a cruising range test to obtain the initial energy consumption value of each fuel. Of course, the WLTC (Worldwide Harmonized Light Vehicles Test Cycle) cruising range standard can also be used to conduct a cruising range test to obtain the initial energy consumption value of each fuel. In this way, in the initial stage, the initial energy consumption value can be used as the current energy consumption value of each fuel, and as the vehicle continues to run, the current energy consumption value of each fuel changes.

[0060] It should be noted that energy consumption usually changes with changes in driving habits, driving conditions, etc.

[0061] S103: The vehicle's cruising range is obtained based on the current energy consumption value of each fuel, the total amount of fuel in the fuel tank and the fuel proportion of each fuel, wherein the current energy consumption value of each fuel is corrected in real time based on the total energy consumption of the vehicle and the fuel proportion of each fuel injected by the engine, and the total energy consumption of the vehicle is obtained based on the total amount of fuel injected by the engine during the current operation of the vehicle.

[0062] As a specific example, the vehicle's cruising range is obtained based on the current energy consumption value of each fuel, the total amount of fuel in the fuel tank, and the fuel proportion of each fuel, including: obtaining the cruising range value of each fuel based on the current energy consumption value of each fuel, the total amount of fuel in the fuel tank, and the fuel proportion of each fuel; obtaining the vehicle's cruising range based on the cruising range value of each fuel.

[0063] Take two fuels such as the first fuel and the second fuel in the above embodiment as an example, the current energy consumption value of the first fuel is recorded as energy consumption value 1, the current energy consumption value of the second fuel is recorded as energy consumption value 2, the total amount of fuel in the fuel tank is assumed to be 45 liters, the fuel proportion of the first fuel is recorded as fuel proportion 1, and the fuel proportion of the second fuel is recorded as fuel proportion 2, wherein fuel proportion 2 = 1 - fuel proportion 1. Then:

[0064] The endurance value of the first fuel = (45*fuel ratio 1) / energy consumption value 1;

[0065] The endurance value of the second fuel = (45*fuel ratio 2) / energy consumption value 2;

[0066] Driving range = driving range of the first fuel + driving range of the second fuel.

[0067] Since the current energy consumption value changes with changes in driving habits, driving conditions, etc., the driving range is constantly revised. In a specific example, the current energy consumption value of each fuel is revised in real time based on the total energy consumption of the vehicle and the fuel proportion of each fuel injected by the engine, wherein the total energy consumption of the vehicle is determined based on the total amount of fuel injected by the engine during the current operation of the vehicle. Specifically, the total energy consumption of the vehicle is determined as follows: Figure 2 As shown, including:

[0068] S201: Obtain the fuel injection amount of the engine.

[0069] After the engine is started, fuel is injected into the engine to keep the engine running. The amount of fuel injected into the engine can be detected by sensors in the engine pipeline.

[0070] S202: Performing time integration on the fuel injection amount of the engine to obtain the total amount of fuel injection that varies with time.

[0071] S203: Obtaining the driving distance of the current operation process;

[0072] S204: According to the driving distance and the total amount of fuel injection, the total energy consumption of the vehicle is obtained, wherein the total energy consumption refers to the energy consumption per 100 kilometers. Thus, according to the driving distance and the total amount of fuel injection, the energy consumption per 100 kilometers, i.e., the total energy consumption, is calculated.

[0073] It should be noted that before the vehicle engine is started, the fuel before fuel replenishment remains in the engine pipeline, and the fuel ratio of each fuel in the fuel is different from the fuel ratio of each fuel after fuel replenishment. Therefore, in order to obtain the injection amount of fuel after fuel replenishment, the engine needs to consume the fuel before fuel replenishment remaining in the engine pipeline. This requires a certain time, namely a predetermined time.

[0074] like Figure 3 As shown, after the total energy consumption of the vehicle is obtained according to the driving distance and the total amount of fuel injection, it also includes:

[0075] S301: Obtaining a fuel ratio of each fuel injected by the engine;

[0076] The fuel proportion of each fuel injected by the engine can be detected by a sensor in the engine pipeline, wherein obtaining the fuel proportion of each fuel injected by the engine specifically includes: obtaining the fuel proportion of each fuel injected by the engine after the engine is started for a predetermined time.

[0077] The scheduled time is obtained as follows:

[0078] Start timing when the engine is started;

[0079] determining whether the fuel remaining in the engine pipeline is consumed according to the total amount of fuel injection;

[0080] If yes, the timing is ended and the timing time is used as the predetermined time.

[0081] Specifically, it is assumed that after the vehicle is refueled, since the fuel before refueling remains in the engine pipeline of the vehicle, the proportion of each fuel in the fuel is different from the fuel proportion of each fuel after refueling. Therefore, in order to obtain the fuel proportion of each fuel after refueling, the engine needs to consume the fuel before refueling remaining in the engine pipeline. This requires a certain time, namely a predetermined time. In other words, after the vehicle is refueled, the fuel proportion of each fuel can be obtained based on the sensor in the engine fuel pipeline after the engine is started for a period of time. The predetermined time is time-integrated according to the amount of fuel injected by the engine, and the time consumed when it is greater than or equal to the fuel volume in the engine pipeline, such as the fuel tank pipeline.

[0082] For example, if the time integration of the engine fuel injection volume is performed, assuming that after 30 seconds, the total amount of fuel injection obtained is 0.01 liters, and the total volume in the engine pipeline is assumed to be 0.01 liters, then the predetermined time can be determined to be 30 seconds. That is, 30 seconds after the engine is started, the fuel proportion of each fuel after fuel replenishment can be obtained through the sensor in the engine fuel pipeline.

[0083] S302: Obtaining a vehicle energy consumption comparison value according to a fuel proportion of each fuel injected by the engine and a current energy consumption value of each fuel.

[0084] Taking two fuels such as the first fuel and the second fuel in the above embodiment as an example, the current energy consumption value of the first fuel is recorded as energy consumption value 1, the current energy consumption value of the second fuel is recorded as energy consumption value 2, the fuel proportion of the first fuel injected by the engine is recorded as fuel proportion 1', and the fuel proportion of the second fuel injected by the engine is recorded as fuel proportion 2', wherein fuel proportion 2'=1-fuel proportion 1'. Then the energy consumption comparison value is:

[0085] Energy consumption comparison value = energy consumption value 1 × fuel proportion 1' + energy consumption value 2 × fuel proportion 2'.

[0086] S303: Compare the energy consumption comparison value of the vehicle with the total energy consumption of the vehicle, and perform real-time correction on the current energy consumption value of each fuel according to the comparison result.

[0087] Specifically, the energy consumption comparison value of the vehicle is compared with the total energy consumption of the vehicle, and the current energy consumption value of each fuel is corrected in real time according to the comparison result, including: if the total energy consumption of the vehicle is greater than the energy consumption comparison value of the vehicle, the current energy consumption value of each fuel is adjusted upward, otherwise, the current energy consumption value of each fuel is adjusted downward.

[0088] That is, if the total energy consumption of the vehicle is greater than the energy consumption comparison value, the energy consumption value 1 and the energy consumption value 2 are adjusted to be greater at the same time, otherwise, the energy consumption value 1 and the energy consumption value 2 are adjusted to be smaller at the same time. It should be noted that the greater the difference between the two, the greater the adjustment amount of the energy consumption value.

[0089] By comparing the energy consumption comparison value of the vehicle with the total energy consumption of the vehicle, the current energy consumption value of each fuel is corrected in real time, and the vehicle's cruising range is calculated based on the current energy consumption value of each fuel, the total amount of fuel in the fuel tank and the fuel proportion of each fuel. Therefore, with the real-time correction of the current energy consumption value of each fuel, the vehicle's cruising range is also corrected in real time, making the cruising range more and more real and reliable.

[0090] It should be noted that the fuel proportion of each fuel injected by the engine is theoretically the same as the fuel proportion of each fuel in the fuel tank. Due to the uniformity of the fuel mixing in the fuel tank, the total energy consumption of the vehicle is calculated using the fuel proportion actually injected by the engine. Therefore, the calculation of the total energy consumption of the vehicle is more accurate and reliable.

[0091] According to the method for calculating the driving range of a flexible fuel vehicle in the embodiment of the present application, the driving range of the vehicle can be obtained in real time according to the current energy consumption value of each fuel, the total amount of fuel in the fuel tank, and the fuel proportion of each fuel in the fuel tank. In addition, the current energy consumption value of each fuel can be corrected in real time according to the total energy consumption of the vehicle and the fuel proportion of each fuel injected by the engine. Therefore, the driving range is also corrected in real time, making the driving range more and more real and reliable, providing users with intuitive, accurate and reliable driving range, and thus effectively improving the vehicle's user experience.

[0092] Figure 4 FIG. 1 is a block diagram of a system for calculating the driving range of a flexible fuel vehicle according to an embodiment of the present application. Figure 4 As shown, a mileage calculation system for a flexible fuel vehicle according to an embodiment of the present application includes: an acquisition module 410, an energy consumption value determination module 420 and a calculation module 430, wherein:

[0093] An acquisition module 410 is used to obtain the total amount of fuel in the fuel tank of the vehicle and the fuel proportion of each fuel;

[0094] The energy consumption value determination module 420 is used to obtain the current energy consumption value of each fuel;

[0095] The calculation module 430 is used to obtain the vehicle's cruising range based on the current energy consumption value of each fuel, the total amount of fuel in the fuel tank and the fuel proportion of each fuel, wherein the current energy consumption value of each fuel is corrected in real time based on the total energy consumption of the vehicle and the fuel proportion of each fuel injected by the engine, and the total energy consumption of the vehicle is obtained based on the total amount of fuel injected by the engine during the current operation of the vehicle.

[0096] According to the driving range calculation system of the flexible fuel vehicle of the embodiment of the present application, the driving range of the vehicle can be obtained in real time according to the current energy consumption value of each fuel, the total amount of fuel in the fuel tank, and the fuel proportion of each fuel in the fuel tank. In addition, the current energy consumption value of each fuel can be corrected in real time according to the total energy consumption of the vehicle and the fuel proportion of each fuel injected by the engine. Therefore, the driving range is also corrected in real time, making the driving range more and more real and reliable, providing users with intuitive, accurate and reliable driving range, thereby effectively improving the use experience of the vehicle.

[0097] The specific definition of the driving range calculation system for flexible fuel vehicles can be found in the definition of the driving range calculation method for flexible fuel vehicles mentioned above, which will not be repeated here. The various modules of the above-mentioned driving range calculation system for flexible fuel vehicles can be implemented in whole or in part by software, hardware and their combination. The above-mentioned modules can be embedded in or independent of the processor in the computer device in the form of hardware, or can be stored in the memory of the computer device in the form of software, so that the processor can call and execute the operations corresponding to the above modules.

[0098] In one embodiment, a vehicle is provided, comprising: a driving range calculation system for a flexible fuel vehicle according to any one of the above embodiments. The vehicle can obtain the driving range of the vehicle in real time according to the current energy consumption value of each fuel, the total amount of fuel in the fuel tank, and the fuel proportion of each fuel in the fuel tank. In addition, the current energy consumption value of each fuel can be corrected in real time according to the total energy consumption of the vehicle and the fuel proportion of each fuel injected by the engine. Therefore, the driving range is also corrected in real time, making the driving range more and more real and reliable, providing users with intuitive, accurate and reliable driving range, thereby effectively improving the use experience of the vehicle.
