[0002] A flexible-fuel vehicle is a vehicle equipped with a flexible-fuel internal combustion 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, different types of fuel are added to the same fuel tank, and the fuel tank is usually not equipped with a fuel ratio sensor. Therefore, after the vehicle is refueled, it is impossible to determine the ratio of each fuel in the fuel tank. Since the energy consumption values ​​of different types of fuels are different, it is impossible to determine the vehicle's range after refueling in a timely manner. The range cannot be updated in time, and usually still displays the range before refueling. Users cannot intuitively feel the improvement in range after refueling, causing user complaints. The range is usually updated after the vehicle has been running for a period of time. The fuel ratio detected by the fuel sensor in the internal combustion engine pipeline is used to determine the new range and update it. The lag is relatively obvious, affecting the vehicle's user experience. Summary of the invention

[0042] 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.

[0043] 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.

[0044] The following describes in detail the driving range calculation method, system, vehicle and device of a flexible fuel vehicle according to an embodiment of the present application in conjunction with the accompanying drawings.

[0045] Before describing the cruising range calculation method, system, vehicle and equipment 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 internal combustion 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.

[0046] 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 1 As 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:

[0047] S101: After a fuel tank of a vehicle is refilled with fuel, a total amount of fuel in the fuel tank is obtained.

[0048] Refueling a vehicle's fuel tank refers to replenishing the vehicle's energy, 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 ratio of the various fuels in the fuel tank will change, and the vehicle's energy consumption values ​​for different types of fuels are usually different. Therefore, when any fuel is added to the fuel tank, it will affect the vehicle's cruising range. Since the ratio of the various fuels in the fuel tank will change, it becomes difficult to calculate the cruising range. The present invention is to solve this technical problem. First, after the vehicle's fuel tank is refueled, it is necessary to obtain the total amount of fuel in the fuel tank.

[0049] In one embodiment of the present invention, after the fuel tank of the vehicle is refueled, the total amount of fuel in the fuel tank is obtained, including: obtaining a fuel level value in the fuel tank; and obtaining a fuel volume according to the fuel level value, wherein the fuel volume represents the total amount of fuel.

[0050] Specifically, the fuel tank is provided with a liquid level sensor for detecting the liquid level. After the vehicle's fuel tank is refueled, the liquid level of the fuel in the fuel tank detected by the liquid level sensor changes, and thereby the liquid level value of the vehicle's fuel tank after refueling can be known. Furthermore, 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 occupies 3 / 4 of the height within the total capacity, such as 3 / 4 of 60 liters is 45 liters.

[0051] The accuracy of the fuel volume in the fuel tank will affect the accuracy of the cruising range calculation. Therefore, in one embodiment of the present invention, before obtaining the fuel volume according to the fuel level value, it also includes: filtering the fuel level value. 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.

[0052] S102: Obtain the energy consumption value of each fuel in the fuel tank.

[0053] The energy consumption value of each fuel may be determined based on the historical energy consumption of each fuel, and the energy consumption value of each fuel may be obtained from the historical records of the energy consumption value of each fuel, that is, the historical energy consumption value.

[0054] Assume that there are two kinds of fuel in the fuel tank, which are recorded as the first fuel and the second fuel, and the historical energy consumption of the first fuel is recorded as energy consumption value 1, and the historical energy consumption of the second fuel is recorded as energy consumption value 2. Then, the historical energy consumption of the first fuel, i.e., energy consumption value 1, and the historical energy consumption of the second fuel, i.e., energy consumption value 2, can be obtained from the historical records.

[0055] In this example, the first fuel may be gasoline and the second fuel may be ethanol.

[0056] S103: Obtaining a fuzzy value of the driving range according to the total amount of fuel in the fuel tank and the energy consumption value of each fuel, and updating the driving range display according to the fuzzy value.

[0057] In a specific example, a fuzzy value of the driving range is obtained based on the total amount of fuel in the fuel tank and the energy consumption value of each fuel, including: obtaining the driving range value of each fuel based on the total amount of fuel and the energy consumption value of each fuel; obtaining the fuzzy value of the driving range based on the number of fuel types and the driving range value of each fuel.

[0058] In this example, the cruising range value of each fuel is obtained according to the total amount of fuel and the energy consumption value of each fuel, for example, the total amount of fuel*the energy consumption value of each fuel is used, so as to obtain the cruising range value of each fuel. Further, the fuzzy value of the cruising range is obtained according to the number of fuel types and the cruising range value of each fuel, for example, the cruising range value of each fuel is added to obtain the total, and then the fuzzy value of the cruising range is obtained by the total / number of types.

[0059] Taking two fuels as an example, such as the first fuel and the second fuel in the above embodiment, the energy consumption value of the first fuel is energy consumption value 1, and the energy consumption value of the second fuel is energy consumption value 2, then it can be determined that the total amount of fuel is 2, and the fuel volume is assumed to be 45, then:

[0060] The endurance value of the first fuel = 45 / energy consumption value 1;

[0061] The second fuel's endurance value = 45 / energy consumption value 2;

[0062] The fuzzy value of the driving range=(the driving range value of the first fuel+the driving range value of the second fuel) / 2.

[0063] After obtaining the fuzzy value of the driving range, the driving range display can be updated in a timely manner. For example, the driving range can be displayed on the vehicle instrument or the vehicle screen. Of course, the driving range can also be sent to the user's smart terminal through the Internet of Vehicles and displayed on the user's smart terminal. Among them, the smart terminal is but not limited to a smart phone, a tablet computer, etc.

[0064] According to the method for calculating the driving range of a flexible fuel vehicle of an embodiment of the present invention, after the vehicle is refueled, the driving range can be determined in time and the driving range display can be updated through the total amount of fuel in the fuel tank and the energy consumption value of each fuel. Compared with the prior art, after the vehicle is refueled, it is impossible to determine the proportion of each fuel in the fuel tank, and thus the driving range cannot be determined and the driving range display cannot be updated in time, and the driving range before the fuel is usually displayed, which causes user dissatisfaction and the user cannot intuitively feel the improvement in driving range. In comparison, after the vehicle is refueled, the driving range can be updated and displayed in time, so that the user can quickly and intuitively feel the improvement in driving range after the vehicle is refueled, thereby effectively improving the use experience of the vehicle.

[0065] like Figure 2 As shown, in one embodiment of the present invention, the method for calculating the driving range of a flexible fuel vehicle, after updating the driving range display according to the fuzzy value, further includes:

[0066] S201: After the internal combustion engine of the vehicle is started for a predetermined time, the fuel proportion of each fuel in the internal combustion engine is obtained.

[0067] In a specific example, the predetermined time is obtained in the following manner: start timing when the internal combustion engine is started; perform time integration on the fuel injection amount of the internal combustion engine to obtain the total amount of fuel injection that changes with time; determine whether the fuel remaining in the internal combustion engine pipeline is consumed based on the total amount of fuel injection; if so, end timing and use the timing time as the predetermined time.

[0068] The internal combustion engine pipeline of the vehicle contains fuel before refueling, and the proportion of each fuel in the fuel is different from the proportion of each fuel after refueling. Therefore, in order to obtain the fuel proportion of each fuel after refueling, the internal combustion engine needs to consume the fuel before refueling remaining in the internal combustion engine pipeline. This requires a certain time, namely a predetermined time. In other words, after the vehicle is refueled and the internal combustion engine is started for a period of time, the fuel proportion of each fuel can be obtained based on the sensor in the engine fuel pipeline. The predetermined time is time-integrated according to the injection amount of the internal combustion engine, and the time consumed when it is greater than or equal to the fuel volume in the internal combustion engine pipeline, such as the fuel tank pipeline.

[0069] For example, if the fuel injection amount of the internal combustion engine is integrated over time, assuming that after 30 seconds, the total amount of fuel injection of the internal combustion engine is 0.01 liters, and the total volume in the internal combustion 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 internal combustion engine is started, the fuel proportion of each fuel after fuel replenishment can be obtained through the sensor in the engine fuel pipeline.

[0070] S202: Obtaining a real cruising range value of the fuel in the fuel tank according to the total amount of fuel, the fuel proportion of each fuel, and the energy consumption value.

[0071] Take two fuels as an example, such as the first fuel and the second fuel in the above embodiment, the energy consumption value of the first fuel is energy consumption value 1, the energy consumption value of the second fuel is energy consumption value 2, and the fuel volume is assumed to be 45. In addition, in step S201, it is assumed that the fuel proportion of the first fuel after fuel replenishment is 80%, and the fuel proportion of the second fuel is 20%. The calculation of the actual cruising range is as follows:

[0072] Actual battery life value = (45*80%) / energy consumption value 1 + (45*20%) / energy consumption value 2.

[0073] S203: Dynamically correct the fuzzy value according to the real endurance value.

[0074] The fuzzy value is corrected according to the real endurance value, and a gradual correction method, i.e., dynamic correction, is adopted. Generally speaking, there is a difference between the real endurance value and the fuzzy value. If the fuzzy value is directly corrected to the real endurance value, the displayed endurance will jump. The greater the difference between the real endurance value and the fuzzy value, the more obvious the jump is, which is easy to cause user complaints. Based on this, in the embodiment of the present invention, a gradual correction method, i.e., dynamic correction, is adopted to avoid user complaints caused by the displayed endurance jump.

[0075] Specifically, the fuzzy value is dynamically corrected according to the actual endurance value, including: dividing the fuzzy value and the actual endurance value to obtain a correction amount of the fuzzy value; obtaining the actual driving distance of the vehicle; and correcting the fuzzy value according to the correction amount each time the actual driving distance of the vehicle reaches a preset unit distance, so as to display the endurance according to the corrected fuzzy value.

[0076] For example: According to the deviation between the fuzzy value and the real endurance value, the fuzzy value is dynamically corrected, and the displayed endurance decreases according to the preset unit distance of each driving (for example, 1 kilometer): fuzzy value / real endurance value, in kilometers. Specifically, assuming that the fuzzy value is 400 kilometers and the real value is 500 kilometers, 400 / 500=0.8 kilometers. Then: the initial displayed endurance is 400 kilometers, and the displayed endurance decreases by 0.8 kilometers for every kilometer the vehicle travels. For example: after driving the first 1 kilometer, the displayed endurance becomes: 399.2 kilometers. In this way, as the driving distance continues to increase, the difference between the fuzzy value and the real endurance value becomes smaller and smaller, and then the endurance intuitively felt by the user is gradually decreasing and getting closer and closer to the real thing. In this way, it not only avoids user dissatisfaction caused by endurance jumps, but also provides users with reliable endurance guidance.

[0077] Figure 3 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 3 As shown, according to an embodiment of the present application, a mileage calculation system for a flexible fuel vehicle includes: a total fuel amount acquisition module 310, an energy consumption value acquisition module 320 and a calculation module 330, wherein:

[0078] A fuel total amount acquisition module 310 is used to obtain the total amount of fuel in the fuel tank after the fuel tank of the vehicle is refilled with fuel;

[0079] The energy consumption value acquisition module 320 is used to acquire the energy consumption value of each fuel in the fuel tank;

[0080] The calculation module 330 is used to obtain a fuzzy value of the driving range according to the total amount of fuel in the fuel tank and the energy consumption value of each fuel, and to update the driving range display according to the fuzzy value.

[0081] According to the driving range calculation system of the flexible fuel vehicle of the embodiment of the present invention, after the vehicle is refueled, the driving range can be determined in time and the driving range display can be updated through the total amount of fuel in the fuel tank and the energy consumption value of each fuel. Compared with the prior art, after the vehicle is refueled, it is impossible to determine the proportion of each fuel in the fuel tank, and thus the driving range cannot be determined and the driving range display cannot be updated in time, and the driving range before the fuel is usually displayed, which causes user dissatisfaction and the user cannot intuitively feel the improvement in driving range. In comparison, after the vehicle is refueled, the driving range can be updated and displayed in time, so that the user can quickly and intuitively feel the improvement in driving range after the vehicle is refueled, thereby effectively improving the use experience of the vehicle.

[0082] In one embodiment of the present invention, in the driving range calculation system of a flexible fuel vehicle, after updating the driving range display according to the fuzzy value, the calculation module 330 is further used to:

[0083] After the vehicle's internal combustion engine is started for a predetermined time, the fuel proportion of each fuel in the internal combustion engine is obtained. The predetermined time is obtained by: starting timing when the internal combustion engine is started; integrating the fuel injection amount of the internal combustion engine over time to obtain the total amount of fuel injection that changes with time; judging whether the fuel retained in the internal combustion engine pipeline is consumed according to the total amount of fuel injection; if so, ending timing and using the timing time as the predetermined time.

[0084] The internal combustion engine pipeline of the vehicle contains fuel before refueling, and the proportion of each fuel in the fuel is different from the proportion of each fuel after refueling. Therefore, in order to obtain the fuel proportion of each fuel after refueling, the internal combustion engine needs to consume the fuel before refueling remaining in the internal combustion engine pipeline. This requires a certain time, namely a predetermined time. In other words, after the vehicle is refueled and the internal combustion engine is started for a period of time, the fuel proportion of each fuel can be obtained based on the sensor in the engine fuel pipeline. The predetermined time is time-integrated according to the injection amount of the internal combustion engine, and the time consumed when it is greater than or equal to the fuel volume in the internal combustion engine pipeline, such as the fuel tank pipeline.

[0085] For example, if the fuel injection amount of the internal combustion engine is integrated over time, assuming that after 30 seconds, the total amount of fuel injection of the internal combustion engine is 0.01 liters, and the total volume in the internal combustion 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 internal combustion engine is started, the fuel proportion of each fuel after fuel replenishment can be obtained through the sensor in the engine fuel pipeline.

[0086] According to the total amount of fuel, the fuel proportion of each fuel and the energy consumption value, the real cruising range value of the fuel in the fuel tank is obtained. Take two fuels as an example, such as the first fuel and the second fuel in the above embodiment, the energy consumption value of the first fuel is energy consumption value 1, the energy consumption value of the second fuel is energy consumption value 2, and the fuel volume is assumed to be 45. In addition, assuming that the fuel proportion of the first fuel after fuel replenishment is 80% and the fuel proportion of the second fuel is 20% through the sensor in the engine fuel line, the real cruising range value is calculated as follows:

[0087] Actual battery life value = (45*80%) / energy consumption value 1 + (45*20%) / energy consumption value 2.

[0088] According to the real endurance value, the fuzzy value is dynamically corrected. Specifically, the fuzzy value is corrected according to the real endurance value, and a gradual correction method, i.e., dynamic correction, is adopted. Generally speaking, there is a difference between the real endurance value and the fuzzy value. If the fuzzy value is directly corrected to the real endurance value, the displayed endurance will jump. The greater the difference between the real endurance value and the fuzzy value, the more obvious the jump is, which is easy to cause user complaints. Based on this, in an embodiment of the present invention, a gradual correction method, i.e., dynamic correction, is adopted to avoid user complaints caused by the displayed endurance jump.

[0089] Specifically, the fuzzy value is dynamically corrected according to the actual endurance value, including: dividing the fuzzy value and the actual endurance value to obtain a correction amount of the fuzzy value; obtaining the actual driving distance of the vehicle; and correcting the fuzzy value according to the correction amount each time the actual driving distance of the vehicle reaches a preset unit distance, so as to display the endurance according to the corrected fuzzy value.

[0090] For example: According to the deviation between the fuzzy value and the real endurance value, the fuzzy value is dynamically corrected, and the displayed endurance decreases for every 1 kilometer of driving: fuzzy value / real endurance value, in kilometers. Specifically, assuming that the fuzzy value is 400 kilometers and the real value is 500 kilometers, 400 / 500=0.8 kilometers. Then: At first, the displayed endurance is 400 kilometers, and the displayed endurance decreases by 0.8 kilometers for every 1 kilometer the vehicle travels. For example: After driving the first 1 kilometer, the displayed endurance changes to: 399.2 kilometers. In this way, as the driving distance continues to increase, the difference between the fuzzy value and the real endurance value becomes smaller and smaller, and then the endurance intuitively felt by the user is gradually decreasing and getting closer and closer to the real endurance. In this way, it not only avoids user dissatisfaction caused by endurance jumps, but also provides users with reliable endurance guidance.

[0091] 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.

[0092] 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. After refueling, the vehicle can timely determine the driving range and update the driving range display through the total amount of fuel in the fuel tank and the energy consumption value of each fuel. Compared with the prior art, after the vehicle is refueled, it is impossible to determine the proportion of each fuel in the fuel tank, and thus the driving range cannot be determined and the driving range display cannot be updated in time, and the driving range before the fuel is usually displayed, which causes user dissatisfaction and the user cannot intuitively feel the improvement in driving range. After the vehicle is refueled, the driving range can be updated and displayed in time, so that the user can quickly and intuitively feel the improvement in driving range after the vehicle is refueled, thereby effectively improving the use experience of the vehicle.
