Description

[0002] In recent years, new energy vehicles have developed rapidly, and gas vehicles have received widespread attention due to their high efficiency and low pollution. The fuel used by gas vehicles is natural gas or hydrogen. The equipment used to store gas on gas vehicles is a gas storage system, which includes one or more gas cylinders. The gas is stored in the gas cylinder in a gaseous state. During the driving process, the gas in the gas cylinder will continue to consume the gas. As the gas vehicle drives, the gas in the gas cylinder will continue to be consumed. Unless the gas is added, the cruising range of the gas vehicle will gradually decrease.

[0003] Since the gas stored in the vehicle is limited, as the gas is used, the gas vehicle may run out of fuel during driving and affect normal driving. In order to avoid this situation, the vehicle's cruising range needs to be displayed to remind the driver of the gas vehicle's cruising range under the current remaining gas volume, so as to help the driver plan the route based on the gas vehicle's cruising range.

[0072] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0073] Application Overview

[0074] In recent years, new energy vehicles have developed rapidly, and gas vehicles have received widespread attention due to their high efficiency and low pollution. The fuel used by gas vehicles is natural gas or hydrogen. The equipment used to store gas on gas vehicles is a gas storage system, which includes one or more gas cylinders. The gas is stored in the gas cylinder in a gaseous state. During the driving process, the gas in the gas cylinder will continue to consume the gas. As the gas vehicle drives, the gas in the gas cylinder will continue to be consumed. Unless the gas is added, the cruising range of the gas vehicle will gradually decrease.

[0075] Since the gas stored in the vehicle is limited, as the gas is used, the gas vehicle may run out of fuel during driving, affecting normal driving. In order to avoid this situation, the vehicle's cruising range needs to be displayed to remind the driver of the gas vehicle's cruising range under the current remaining gas amount.

[0076] In order to solve the above problems, the present application provides a first cruising range and a second cruising range calculated based on two different strategies. Specifically, the first cruising range is a cruising range calculated based on the driving conditions in the past period of time, and the prediction result is more accurate when the future road conditions are close to the road conditions in the past period of time; the second cruising range is calculated based on the current driving conditions, and the prediction result is more accurate when the future road conditions are close to the current road conditions. An embodiment of the present application provides the above two prediction results. The embodiment of the present application first calculates the above two prediction results, and then determines which prediction result is closer to the actual vehicle cruising range based on the road conditions in the future, and displays the prediction result of the first cruising range and the second cruising range that is closer to the actual cruising range, so that the cruising range displayed to the driver is more in line with the actual cruising range, so as to facilitate the driver to plan the route and avoid affecting the normal driving of the vehicle due to running out of fuel.

[0077] After introducing the basic principles of the present application, various non-limiting embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0078] Exemplary Methods

[0079] Figure 1 FIG. 1 is a flow chart of a method for displaying a range of mileage provided by an embodiment of the present application. Figure 1 As shown, the cruising range display method includes the following contents.

[0080] S110, obtaining the current gas cylinder pressure, the current gas consumption rate, the initial gas cylinder pressure at a historical moment, the historical road conditions, and the future road conditions;

[0081] Among them, the historical road conditions include: the historical section driving distance and the historical section slope information of the vehicle driving section within the target driving time corresponding to the historical moment to the current moment; the historical road conditions corresponding to the historical section driving distance can be collected based on the sensors set on the vehicle or the vehicle's own control system. Future road conditions include: the estimated driving distance and the slope information of the front section corresponding to the driving section between the current position of the vehicle and the preset destination; Among them, the current gas cylinder pressure refers to the pressure of the gas cylinder for storing natural gas or hydrogen in the gas vehicle at the current moment. The current gas consumption rate is given by the engine of the vehicle, and the gas consumed per unit distance of the vehicle under the current working conditions. The historical moment can be any moment before the current moment. The initial gas cylinder pressure at the historical moment refers to the pressure of the gas cylinder for storing natural gas or hydrogen in the gas vehicle at a certain moment before the current moment. Both the current gas cylinder pressure and the initial gas cylinder pressure can be collected based on the preset pressure sensor of the vehicle. In practical applications, in order to make the acquired data more representative, the historical moment can be the starting moment of one minute before the current moment, that is, the time period between the historical moment and the current moment is 1 minute. The historical road section driving distance within the target driving time corresponding to the historical moment to the current moment refers to the driving distance of the vehicle from the historical moment to the current moment; the historical road section slope information refers to the slope of the driving section of the vehicle from the historical moment to the current moment. The future road conditions corresponding to the driving section between the current position of the vehicle and the preset destination can be obtained based on the preset map navigation software or can be pre-input.

[0082] S120, determining a first cruising range of the vehicle based on the current gas cylinder pressure, the initial gas cylinder pressure and the historical road section driving distance.

[0083] It should be noted that the first cruising range is obtained by predicting the cruising range under the premise that the gas consumption rate within the target driving time from the historical moment to the current moment is taken as the gas consumption rate of the vehicle in the future. In step S120, in the process of determining the first cruising range of the vehicle, the current gas cylinder pressure, the initial gas cylinder pressure and the historical road section driving distance are considered, that is, the first cruising range of the vehicle is determined based on the change of the gas cylinder pressure during the driving process from the historical moment to the current moment, the vehicle mileage, and the current gas cylinder pressure. The idea of ​​predicting the first cruising range is: the vehicle operating conditions in the future period are preset to be the same as the vehicle operating conditions from the historical moment to the current moment, so the "relationship between the gas cylinder pressure change and the vehicle mileage during the period from the historical moment to the current moment" is taken as the "relationship between the gas cylinder pressure change and the vehicle mileage in the future period", and then the vehicle's cruising range is predicted to obtain the first cruising range.

[0084] S130, determining a second cruising range of the vehicle based on the current gas bottle pressure and the current gas consumption rate.

[0085] It should be noted that the second cruising range is obtained by predicting the cruising range under the premise of taking the current gas consumption rate as the gas consumption rate of the vehicle in the future. In step S130, in the process of determining the second cruising range of the vehicle, the current gas cylinder pressure and the current gas consumption rate are taken into account, that is, the vehicle mileage is estimated based on the current gas consumption rate and the current gas cylinder pressure at the current moment. The specific idea of ​​predicting the second cruising range is: the vehicle operating conditions in the future period are preset to be the same as the vehicle operating conditions at the current moment, so the "current gas consumption rate" is used as the "gas consumption rate in the future period", and then the vehicle's cruising range is predicted to obtain the second cruising range.

[0086] S140, based on the historical road section driving distance, the historical road section slope information, the estimated driving distance and the road section slope information ahead, determine whether the future road condition is closer to the current road condition than the historical road condition.

[0087] The current road condition is the road condition information at the last moment in the historical road condition, that is, the current slope is the slope information of the last section in the historical section slope information.

[0088] S150: If the road condition of the future road is closer to the road condition of the historical road, the first cruising range is displayed.

[0089] S160: If the road conditions of the future road are closer to the road conditions of the historical road, the second cruising range is displayed

[0090] Specifically, the dashboard of the vehicle can be controlled to display the first cruising range or the second cruising range. Among them, the dashboard of the vehicle can be a display screen. Among them, the first cruising range is the cruising range calculated based on the driving conditions in the past period of time, and the prediction result is more accurate when the future road conditions are close to the road conditions in the past period of time; the second cruising range is the cruising range calculated based on the current driving conditions, and the prediction result is more accurate when the future road conditions are close to the current road conditions. The embodiment of the present application first calculates the above two prediction results, and then determines which prediction result is closer to the actual vehicle cruising range based on the road conditions in the future time, and displays the prediction result that is closer to the actual cruising range of the first cruising range and the second cruising range, so that the cruising range displayed to the driver is more in line with the actual cruising range, so that the driver can plan the route and avoid affecting the normal driving of the vehicle due to running out of fuel.

[0091] In one embodiment, referring to Figure 2Step S120 "determine the first cruising range of the vehicle based on the current gas cylinder pressure, the initial gas cylinder pressure and the historical road section driving distance" may include:

[0092] S121, calculating the difference between the initial gas cylinder pressure and the current gas cylinder pressure to obtain a gas cylinder pressure change value;

[0093] It should be noted that, during the driving process of the vehicle, as the gas in the gas cylinder decreases, the pressure of the gas cylinder also decreases. In a closed container, when other quantities remain unchanged, the amount of gas is proportional to the gas pressure. Therefore, the change in the gas in the vehicle can be reflected based on the change in the gas cylinder pressure.

[0094] S122, calculating the quotient of the gas bottle pressure change value and the historical road section driving distance to obtain a first gas pressure change rate;

[0095] It should be noted that, in a closed container, when other quantities remain unchanged, the amount of gas is proportional to the gas pressure, so the gas consumption rate can be characterized by the first gas pressure change rate.

[0096] S123, calculating the difference between the current gas cylinder pressure and the preset basic pressure value to obtain an available pressure value;

[0097] Among them, the preset basic pressure value is the cylinder pressure when the gas cylinder cannot supply gas; it should be noted that in actual use, as the pressure inside the gas cylinder decreases, the gas cannot be discharged, and the gas inside the gas cylinder cannot be used. Therefore, when calculating the available pressure value or the remaining gas, the amount corresponding to this part of the gas should be eliminated. Furthermore, based on the fact that in a closed container, when other quantities remain unchanged, the amount of gas is proportional to the gas pressure, so the available pressure value can be used to characterize the available remaining gas.

[0098] S124, calculating the quotient of the available pressure value and the first fuel gas pressure change rate to obtain a first cruising range.

[0099] In the embodiment of the present application, the available remaining amount of gas is characterized by the available pressure value, and the gas consumption rate is characterized by the first gas pressure change rate; the quotient of the available pressure value and the first gas pressure change rate is calculated as the first cruising range. In the above process, the calculation is directly based on the pressure of the gas bottle, rather than converting the pressure of the gas bottle into the amount of gas in advance and then calculating, which simplifies the calculation process and makes it possible to obtain the first cruising range more quickly. Furthermore, based on the above process, the first cruising range is the cruising range calculated based on the driving conditions in the past period of time as the future driving conditions. Therefore, when the future vehicle operating conditions are close to the vehicle operating conditions in the past period of time, the future driving conditions are close to the driving conditions in the past period of time, and the prediction results are more accurate at this time.

[0100] In one embodiment, referring to Figure 3 Step 130 “determine the second cruising range of the vehicle based on the current gas bottle pressure and the current gas consumption rate” includes:

[0101] S131, calculating the difference between the current gas cylinder pressure and the preset basic pressure value to obtain an available pressure value;

[0102] The preset basic pressure value is the cylinder pressure when the gas cylinder cannot supply gas. It should be noted that in actual use, as the pressure inside the gas cylinder decreases, the gas cannot be discharged, and the gas inside the gas cylinder cannot be used. Therefore, when calculating the available pressure value or the remaining gas, the amount corresponding to this part of the gas should be eliminated.

[0103] S132, determining the available gas amount based on the available pressure value;

[0104] It should be noted that after determining the available pressure value, the available pressure value can be multiplied by the coefficient to obtain the available gas volume. Specifically, the coefficient is related to data such as the temperature inside the bottle and the size of the gas bottle. The coefficient can be determined in advance or calculated based on current data such as the temperature inside the bottle and the size of the gas bottle.

[0105] S134, calculating the quotient of the available gas amount and the current gas consumption rate to obtain a second cruising range.

[0106] The embodiment of the present application estimates the vehicle mileage based on the current gas bottle pressure and the current gas consumption rate. The idea of ​​predicting the second cruising range is to presuppose that the vehicle operating conditions in the future are the same as the vehicle operating conditions at the current moment, so the "current gas consumption rate" is used as the "gas consumption rate in the future", and then the vehicle's cruising range is predicted to obtain the second cruising range. When the future vehicle's operating conditions are approximately the same as the current vehicle's operating conditions, the prediction result is more accurate.

[0107] In one embodiment, in step S140, "determining whether the future road condition is closer to the current road condition than the historical road condition" includes:

[0108] Based on the slope information of the historical road sections, the driving distance of the historical road sections is weighted to obtain the target historical driving distance; wherein the weighting rule is such that the gas consumption of the vehicle for the weighted distance before driving on the slope is the same as the gas consumption of the vehicle for the weighted distance after driving on the slope; the target historical driving distance is calculated, divided by the driving distance of the historical road section, and multiplied by the driving distance of the previous road section to obtain the first comparison distance; based on the slope information of the previous road section, the driving distance of the previous road section is weighted to obtain the target future driving distance; based on the slope information of the current road section, the driving distance of the previous road section is weighted to obtain the second comparison distance.

[0109] Determine whether the target future driving distance is closer to the second comparison distance than the first comparison distance; if the target future driving distance is closer to the first comparison distance, the road condition of the future road is closer to the road condition of the historical road; if the target future driving distance is closer to the second comparison distance, the road condition of the future road is closer to the road condition of the current road.

[0110] Based on the above scheme, the embodiment of the present application provides a scheme in which the relationship between historical road conditions, future road conditions and current road conditions is mapped based on the first comparison distance, the target future driving distance and the second comparison distance, and the future road conditions are determined to be closer to the historical road conditions and the current road conditions based on the size relationship between the first comparison distance, the target future driving distance and the second comparison distance. Since the weighted process takes into account the gas consumption, the result obtained can reflect whether the future road conditions are closer to the gas consumption of the historical road conditions or the current road conditions, so as to determine the first cruising range to be displayed or the second cruising range to be displayed based on the judgment result.

[0111] It should be noted that, in actual applications, the future driving conditions of gas vehicles may be known. For example, the navigation function provided by some map software can determine the destination of the vehicle and the road conditions of the vehicle's driving section (the road conditions here mainly refer to slope information and distance information). Of course, some vehicles travel on fixed routes and travel back and forth between several fixed destinations. The actual destinations of these vehicles and the road condition information to the destinations can also be obtained in advance. Based on these vehicles, the solution provided in the embodiments of the present application, with reference to Figure 4 , also includes:

[0112] S410, judging whether the vehicle can reach the preset destination based on the current gas cylinder pressure, the initial gas cylinder pressure, the historical road section driving distance, the historical road conditions and the future road conditions;

[0113] It should be noted that, in the solution provided in the embodiment of the present application, compared with the solution for calculating the first cruising distance, full consideration is given to future road condition information, more information is obtained, and more accurate predictions are made based on more information, so that the "judgment result of whether the vehicle can reach the preset destination" obtained is more accurate.

[0114] S420: If it is determined that the vehicle can reach the preset destination, a third cruising range of the vehicle after the vehicle reaches the destination is calculated and displayed.

[0115] It should be noted that after determining that the vehicle can reach the destination, the user's choice is generally to give priority to reaching the destination and then make subsequent arrangements. Therefore, the solution provided in the embodiment of the present application can provide the vehicle's range after the vehicle arrives at the destination, that is, the third range, so that the user can determine the driving plan after arriving at the destination based on the third range.

[0116] It should be noted that historical road conditions include historical road section slope information; future road conditions include the estimated driving distance of the road ahead and the road ahead slope information; Figure 5 Step S420, "determining whether the vehicle can reach the preset destination based on the current gas cylinder pressure, the initial gas cylinder pressure, the historical road section driving distance, the historical road conditions and the future road conditions" may include:

[0117] S411, weighting the historical road section driving distance based on the historical road section slope information to obtain a target historical driving distance;

[0118] The weighted rule is to make the gas consumption of the vehicle traveling the target historical driving distance without a slope the same as the gas consumption of the vehicle traveling the historical road section with a slope;

[0119] For example: the gas consumption of a 1-kilometer journey with a slope of 30° is equal to the gas consumption of a 1.2-kilometer journey with a slope of 0°. When weighted, the 1-kilometer journey with a slope of 30° is weighted to be 1.2 kilometers. For example: the gas consumption of a 1-kilometer journey with a slope of 30° is equal to the gas consumption of a 1.2-kilometer journey with a slope of 0°. When weighted, the 1-kilometer journey with a slope of 30° is weighted to be 1.2 kilometers, which is the target historical driving distance or target future driving distance. If the gas consumption of a 1-kilometer journey with a slope of -30° is equal to the gas consumption of a 0.7-kilometer journey with a slope of 0°, when weighted, the 1-kilometer journey with a slope of -30° is weighted to be 0.7 kilometers, which is the target historical driving distance or target future driving distance.

[0120] S412, obtaining a second gas pressure change rate based on the current gas cylinder pressure, the initial gas cylinder pressure and the target historical driving distance;

[0121] It should be noted that the strategy for calculating the second gas pressure change rate is the same as the strategy for calculating the first gas pressure change rate. The difference lies in the target historical driving distance used when calculating the second gas pressure change rate, that is, the calculation of the second gas pressure change rate is performed while taking the slope into consideration.

[0122] S413, weighting the estimated driving distance based on the slope information of the road section ahead to obtain a target future driving distance;

[0123] It should be noted that the solution provided in the embodiment of the present application is based on the target future driving distance as the future driving distance, corresponding to the target historical driving distance. The road conditions of both can be regarded as a slope of 0°, so the "gas consumption of one kilometer of target historical driving distance" and the "gas consumption of one kilometer of target future driving distance" are basically the same.

[0124] The specific weighting method can be as follows: the road condition of the road section ahead is: the road section distance is k kilometers, of which the road section with a slope of 30° is m kilometers, and the road section with a slope of -30° is n kilometers. Among them, m+n=k. Then the formula for calculating the weighted target future driving distance s is: s=1.2*m+0.7n. It should be noted that the coefficients 1.2 and 0.7 in the formula are determined based on the example provided in the embodiment under step S421. In actual applications, the coefficients are determined based on the actual slope of the road section, and each slope is pre-set with a corresponding coefficient. Still using the example provided under step S421 for explanation, the coefficient corresponding to a slope of 30° is 1.2; the coefficient corresponding to a slope of -30° is 0.7.

[0125] S414, calculating the product of the target future driving distance and the second gas pressure change rate to obtain a target gas cylinder pressure change value;

[0126] The purpose of step S424 is to determine the gas cylinder pressure that needs to be consumed when traveling to the destination, wherein the gas cylinder pressure that needs to be consumed is used to represent the amount of gas that needs to be consumed.

[0127] S415, if the target gas cylinder pressure change value is less than the available pressure value, it is determined that the vehicle can reach the destination;

[0128] The available pressure value is the difference between the current gas cylinder pressure and the preset basic pressure value; the preset basic pressure value is the cylinder pressure when the gas cylinder cannot supply gas. For the specific description of the available pressure value, please refer to the relevant descriptions in step S123 and step S131.

[0129] In the solution provided in the embodiment of the present application, the road condition information of the future road (mainly the slope information) is fully considered, and weighting is performed based on the slope information to make a more accurate prediction, and the obtained "judgment result of whether the vehicle can reach the preset destination" is more accurate.

[0130] In one embodiment, referring to Figure 6 Step S430 “calculate and display the third cruising range of the vehicle after the vehicle arrives at the preset destination” includes:

[0131] S421, calculating the difference between the available pressure value and the target gas cylinder pressure to obtain the target gas pressure margin;

[0132] It should be noted that the target fuel pressure remaining amount is used to represent the estimated fuel remaining amount after the vehicle arrives at the destination.

[0133] S422, calculating the quotient of the target gas pressure margin divided by the second gas change rate to obtain a third cruising range;

[0134] It should be noted that after arriving at the destination, the road conditions for the vehicle to continue driving cannot be determined, so the slope of the distance after the destination can be assumed to be 0. Therefore, the second gas change rate can be directly used as the "gas bottle pressure change rate with driving distance" in the distance after the destination. The third cruising range is calculated based on the second gas change rate.

[0135] S433, displaying the third cruising range.

[0136] With such a configuration, the displayed third cruising range can be used by the user to determine a driving plan after arriving at the destination based on the third cruising range.

[0137] In one embodiment, referring to Figure 4 The method for displaying the mileage provided in the embodiment of the present application further includes:

[0138] S430: If it is determined that the vehicle cannot reach the destination, a fourth cruising range of the vehicle when traveling on the road ahead is calculated and displayed.

[0139] Specifically, when calculating the fourth cruising range, the influence of road conditions on the cruising range can be fully considered with reference to some of the contents in step S420. For example, the road condition of the road section ahead is k kilometers, of which the road section with a slope of 30° is m kilometers and the road section with a medium slope of -30° is n kilometers. Among them, m+n=k. Based on the second gas pressure change rate obtained in step S422 and the available pressure value appearing in step S425, the driving distance that the vehicle can travel on the target future road section is calculated, that is, the quotient of the available pressure value divided by the second gas pressure change rate is calculated to obtain the "driving distance that the vehicle can travel on the target future road section". After that, the fourth cruising range is determined based on the driving distance that the vehicle can travel on the target future road section. For example, "the driving distance that the vehicle can travel on the target future road section" is u. If u=1.2a, then the fourth cruising range is a; if u=1.2m+0.7b. Then the fourth cruising range is m+b. With such a setting, a more accurate prediction can be made on the basis of fully considering the road condition information (slope information) of the future road.
