in the present embodiment, the travel end time of the target travel distance is the position where the vehicle is located at the current time. In other embodiments, the travel end time of the target travel distance may be earlier than the current time.
In this embodiment, the plurality of sub-distances corresponding to the plurality of energy consumption values are consecutive mileage sections, and the sum of all the sub-distances corresponding to the plurality of energy consumption values is the target driving distance. In other embodiments, the plurality of sub-distances corresponding to the plurality of energy consumption values may be non-consecutive mileage sections, and the sum of all the sub-distances corresponding to the plurality of energy consumption values is less than the target driving distance.
In this embodiment, the distance magnitudes of the different sub-distances are the same. In other embodiments, the range magnitudes of the different sub-ranges may be different.
In the present embodiment, the total number of sub distances within the target travel distance is a fixed value set in advance. In other embodiments, the total number of sub-distances within the target travel distance may also be a parameter value determined based on actual vehicle operating parameters.
Each energy consumption value may be determined based on operating parameters of the vehicle within the corresponding sub-distance. Specifically, the energy consumption value is the energy consumption value of the mileage of the vehicle in the corresponding time period.
Specifically, the step S10 may be executed when the vehicle is powered on, the step S10 may also be executed at a set time interval after the vehicle is powered on, and the step S10 may also be executed when the operation of the vehicle reaches a preset condition (for example, an instruction input by a user is received or the remaining energy of the energy module reaches a set energy) after the vehicle is powered on.
Step S20, determining a weight value corresponding to each sub-distance;
the weighted values corresponding to different sub-distances may be fixed values set in advance, or may be parameter values determined according to the actual running state of the vehicle.
Different sub-distances correspond to different weight values. The sum of all the weighted values can be a preset fixed value, and can also be a parameter value determined according to the actual running parameter of the vehicle.
Further, in this embodiment, if the interval duration of the sub-distance and the current time is different, the corresponding weight values are different.
Step S30, determining a reference energy consumption value of the mileage of the vehicle according to the plurality of energy consumption values and the weighted values corresponding to the sub-distances;
and taking the result obtained by performing weighted average calculation on the plurality of energy consumption values according to the plurality of weight values as a reference energy consumption value.
Specifically, the product of each energy consumption value and the corresponding weight value may be calculated, a first sum of all the weight values may be calculated, a second sum of all the products corresponding to all the energy consumption values may be calculated, and a ratio of the second sum to the first sum may be used as the reference energy consumption value.
The reference energy consumption value is in particular the energy consumed by the vehicle per unit of mileage. In the present embodiment, the unit mileage is 1km. In other embodiments, the unit mileage may be other shorter or longer mileage, such as 10km or 500 m.
And S40, determining a first target endurance mileage of the vehicle according to the reference energy consumption value.
Specifically, the residual energy of an energy module of the vehicle is obtained, and the first target endurance mileage is determined according to the residual energy and the reference energy consumption value.
After the first target mileage is obtained, corresponding prompt information can be output according to the first target mileage. And parameters used by other auxiliary vehicles can be determined according to the first target endurance mileage, and corresponding prompt information is output.
The method for determining the endurance mileage of the vehicle provided by the embodiment of the invention is characterized in that a plurality of mileage sections of the energy consumption value of the vehicle within the target driving distance before the current moment are counted, different sub-distances correspond to different weight values, a plurality of energy consumption values within the target driving distance are weighted by the weight values to obtain a reference energy consumption value of the unit mileage of the vehicle driving, and the first target endurance mileage of the vehicle is determined by utilizing the determined reference energy consumption value.
Further, in this embodiment, the number of the plurality of energy consumption values is preset, and the method for determining the driving mileage of the vehicle further includes: when the vehicle leaves the factory or receives a reset instruction of the endurance mileage, the preset energy consumption values corresponding to the sub-distances respectively can be obtained, and a plurality of energy consumption values are obtained.
Specifically, when the vehicle is in a driving stage of driving for the first time after leaving a factory or powering on the vehicle after receiving a reset instruction, if the interval duration between the current time and the vehicle powering on time is less than the target driving distance, determining that the sub-distance of the plurality of sub-distances, in which the driving time is earlier than the powering on time, is a first sub-distance, determining that the driving time of the plurality of sub-distances is later than or includes the powering on time, is a second sub-distance, determining a preset energy consumption value corresponding to each first sub-distance as an energy consumption value corresponding to the first sub-distance, determining an actual energy consumption value determined by the vehicle operation parameter within each second sub-distance as an energy consumption value corresponding to the second sub-distance, and obtaining a plurality of energy consumption values.
Based on the method, the effective endurance mileage of the vehicle can be obtained no matter after leaving the factory or after the endurance mileage is output.
Further, based on the above embodiments, another embodiment of the vehicle driving range determining method is provided. In this embodiment, referring to fig. 3, the step S20 includes:
step S21, obtaining a sorting characteristic value corresponding to each sub-distance, wherein the shorter the interval duration between the sub-distance and the current time is, the smaller the corresponding sorting characteristic value is;
the sorting characteristic value may be a sequence number set by a plurality of sub-distances based on a time interval from the current time, and a numerical interval between two adjacent sequence numbers is 1. In other embodiments, the value of the ranking characteristic may be any other value that reflects the ranking characteristic.
For example, if the target travel distance is defined to be 6T, the plurality of sub-distances are (0,0.01T ], (0.01t, 0.02t ], (0.02t, 0.03t ] … … (5.99t, 6T) in order from short to long based on the interval duration from the current time, and the corresponding ranking characteristic values are 1, 2, 3 … 100 … … 599, 600 in order.
Step S22, determining the weight value according to the sorting characteristic value, wherein the sorting characteristic value is positively correlated with the weight value.
Different ranking characteristic values may correspond to different weight values. Specifically, a corresponding relationship between the sorting characteristic value and the weight value may be preset, and the corresponding relationship may include a calculation relationship, a mapping relationship, and the like. Based on the corresponding relation, the weight value corresponding to the sorting characteristic value can be determined.
Further, in this embodiment, the weighting value increases exponentially with the increase of the ranking characteristic value. Specifically, the weight value Y (T) = e ^ (-T/T), where T is determined according to the sorting characteristic value and the distance amplitude of the sub-distance, and T is the target travel distance.
In this embodiment, in the above manner, the longer the interval duration between the sub-distance and the current time is, the larger the corresponding weight value is, and based on this, the influence of the sudden change of the vehicle driving condition, which is generated within the shorter duration of the time interval at the current time, on the driving range calculation can be effectively reduced, so that the accuracy of the determined driving range is further improved. The weighted value is exponentially increased along with the increase of the sorting characteristic value, so that the running condition of the vehicle is more fit, and the accuracy of the determined endurance mileage is further improved.
Further, based on any one of the embodiments, another embodiment of the vehicle driving range determining method is provided. In this embodiment, referring to fig. 4, before step S10, the method further includes:
step S01, acquiring the current residual energy of the vehicle;
in the present embodiment, the remaining energy is the remaining amount of the vehicle. In other embodiments, the remaining energy may be the amount of oil remaining in the vehicle.
And S02, determining the target driving distance according to the residual energy.
Different remaining energies correspond to different target travel distances. Specifically, a corresponding relationship between the remaining energy and the target travel distance may be established in advance, and the corresponding relationship may include a mapping relationship, and the like. The target travel distance corresponding to the current remaining energy may be determined based on the correspondence relationship. Specifically, a value interval where the residual energy is located may be determined, and a preset distance value set corresponding to the value interval may be determined as the target travel distance.
In this embodiment, when the remaining energy is greater than or equal to a preset energy, determining that the first distance is the target travel distance; when the residual energy is smaller than the preset energy, determining a second distance as the target driving distance; the first distance is greater than the second distance.
The preset electric quantity is specifically an electric quantity critical value used for distinguishing whether the energy of an energy module of the vehicle is too low. If the residual energy is greater than or equal to the preset energy, the situation that the energy is not too low is indicated; a remaining energy less than the preset energy indicates an energy that is too low.
In the present embodiment, the remaining energy includes a remaining energy (SOC), and the target travel distance T corresponding to different remaining energies may be shown in the following table:
| SOC | 0％ | 20％ | 40％ | 60％ | 80％ | 100％ |
| T | 50 | 180 | 180 | 180 | 180 | 180 |
wherein 20% of the predetermined energy may be the predetermined energy, the first distance is 180, and the second distance is 50.
It should be noted that specific values of the target travel distance corresponding to different residual energies may be set according to actual situations, for example, the residual energies and the target travel distance of different vehicle types may have different corresponding relationships.
In the embodiment, the target driving distance for determining the driving range is determined based on the remaining energy of the vehicle, which is beneficial to ensuring the matching degree of the determined driving range and the current remaining energy of the vehicle and further improving the accuracy of the driving range. The low-energy target driving distance is adopted when the energy is low, so that the influence on the energy consumption of the vehicle caused by the working condition change in a short time can be reflected in the endurance mileage in time, the energy can be supplemented to a user in time based on the endurance mileage, and the endurance capacity of the vehicle is improved; when the energy is high, a larger target driving distance is adopted, the influence of accidental working condition mutation on energy consumption is favorably reduced, the obtained energy consumption values can accurately reflect the whole energy consumption condition of the vehicle in a long time, and the determined endurance mileage can accurately reflect the endurance capacity of the vehicle.
