The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
The following describes in detail a method, an apparatus, an electronic device, and a storage medium for estimating remaining mileage of a vehicle provided by the present application with reference to the accompanying drawings.
The method for estimating the remaining mileage of the vehicle according to the embodiment of the present application can be performed by the apparatus for estimating the remaining mileage of the vehicle according to the embodiment of the present application, and the apparatus can be configured in an electronic device.
The electronic device may be configured at a vehicle end, or may be configured at any server side connected to the vehicle through a network, and the server may count relevant data such as historical usage data of the battery, so as to estimate the remaining mileage of the vehicle.
Fig. 1 is a schematic flowchart of a method for estimating remaining mileage of a vehicle according to an embodiment of the present disclosure.
As shown in fig. 1, the method for estimating remaining mileage of a vehicle includes the steps of:
The current remaining capacity of the battery in the vehicle may be data transmitted from the vehicle to the server. The position of the vehicle may be determined by obtaining positioning information from a positioning module in the vehicle-mounted system and then transmitting the positioning information to the server. The historical usage data of the battery may be data stored locally by the server.
In addition, the current location information of the vehicle may include provinces, cities, regions, streets, latitudes and longitudes, which are not limited in the present application.
It can be understood that the information of the current location of the vehicle may be directly obtained through a positioning system of the vehicle, may also be determined according to a surrounding environment, or may also be obtained in other manners, which is not limited in this application.
It should be noted that the server may obtain, in addition to the current remaining capacity of the battery in the vehicle to be estimated, the historical usage data of the battery, and the current location information of the vehicle, other relevant data that may affect the operating state of the battery, which is not limited in this application.
And 102, determining the current discharge coefficient of the battery according to the current position information of the vehicle and the historical use data of the battery.
The historical usage data of the battery may include historical usage data of the battery, a discharge depth of each time, and the like, which is not limited in the present application. The depth of discharge of a battery may represent the percentage of the battery's discharge capacity to the rated capacity of the battery.
In addition, the discharge coefficient of the battery may be a discharge rate of the battery, or any coefficient that can be used to represent a discharge speed of the battery, which is not limited in this application.
It can be understood that, when determining the current discharge coefficient of the battery, the current discharge coefficient of the battery may be determined according to the corresponding relationship between the position of the vehicle, the historical use data of the battery, and the discharge coefficient of the battery. Or special operation can be performed on the position of the vehicle and the historical use data of the battery, and the operation result and the discharge coefficient of the battery are mapped one by one to obtain a mapping table, so that the current discharge coefficient of the battery can be determined according to the operation result.
It should be noted that, the above manner for determining the current discharge coefficient of the battery is only an example, and cannot be taken as a limitation for determining the current discharge coefficient of the battery in the embodiment of the present application.
And 103, determining the current remaining mileage of the vehicle to be estimated according to the current discharge coefficient and the current remaining capacity of the battery.
Wherein, the server can determine when to estimate the remaining mileage of the vehicle according to actual needs.
For example, the remaining mileage of the vehicle may be estimated in real time, so that the user can obtain the remaining mileage in real time, thereby relieving the anxiety of the user's mileage.
Alternatively, in order to reduce the burden on the processor, the remaining mileage of the vehicle may be estimated at intervals, such as every 10 minutes, every half hour, and the like, which is not limited in this application.
Alternatively, different frequencies can be set for estimation according to different electric quantities.
For example, when the capacity is more than eighty percent, the remaining mileage may be estimated every one hour, the capacity is from fifty to eighty percent, the remaining mileage may be estimated every twenty minutes, and the capacity is less than fifty percent, and the remaining mileage may be estimated every five minutes and ten minutes.
Or, a corresponding control button is arranged in the vehicle, and when the server detects that the user triggers the control button, the remaining mileage of the vehicle can be estimated. Or, a corresponding control is set on the application software capable of controlling the vehicle, and the server detects that the user can estimate the remaining mileage of the vehicle by triggering the control.
It should be noted that the above examples are only illustrative and should not be taken as a limitation to the determination of the estimated remaining vehicle mileage in the embodiments of the present application.
For example, when the current discharge coefficient of the battery is a, and the current remaining capacity of the battery is also large, the determined current remaining mileage value of the vehicle to be estimated may be relatively large.
Or when the current discharge coefficient of the battery is B and the current remaining capacity of the battery is less, the determined current remaining mileage value of the vehicle to be estimated may be relatively small, and the user can prepare in advance, charge in time or change the journey and the like according to the determined remaining mileage value.
According to the method and the device, the current remaining mileage of the vehicle to be estimated can be accurately determined according to the current discharge coefficient and the current remaining capacity of the battery, the accuracy of determining the remaining mileage is improved, and therefore a user can be better helped.
According to the method and the device for estimating the remaining mileage of the vehicle, the current remaining capacity of the battery, the historical use data of the battery and the current position information of the vehicle in the vehicle to be estimated are obtained, then the current discharging coefficient of the battery is determined according to the current position information of the vehicle and the historical use data of the battery, and then the current remaining mileage of the vehicle to be estimated is determined according to the current discharging coefficient of the battery and the current remaining capacity. Therefore, the server can accurately determine the current remaining mileage of the vehicle according to the acquired data such as the remaining electric quantity of the battery and the current position information of the vehicle, so that the accuracy of remaining mileage estimation is further improved, an accurate remaining mileage estimation value can be provided for a user, the user can conveniently master the remaining mileage condition in real time, and the user can be helped to travel better.
In the embodiment, the current remaining mileage of the vehicle to be estimated is determined according to the acquired relevant data such as the current remaining capacity of the battery and the current position information of the vehicle. In order to further improve the accuracy of the determined remaining mileage, the current remaining mileage may be corrected, and a driving recommendation may be provided to the user according to the relationship between the remaining mileage and the destination, which is described in detail below with reference to fig. 2.
Fig. 2 is a schematic flowchart of a method for estimating remaining mileage of a vehicle according to another embodiment of the present application.
Wherein the discharge coefficient of the battery may change as the number of uses increases. For example, a fully charged battery may travel 40 kilometers at a time initially, and as the number of uses increases, a fully charged battery may travel only 30 kilometers at a time.
And step 203, determining the current ambient temperature of the vehicle according to the current position information of the vehicle.
The weather and temperature condition of the current position can be determined according to the acquired position information of the current position of the vehicle, and the temperature is the current ambient temperature of the vehicle.
And 204, correcting the initial discharge coefficient according to the environment temperature to determine the current discharge coefficient.
Wherein the ambient temperature may have an effect on the battery discharge coefficient.
For example, for a storage battery, a good working state can be maintained at 15-25 ℃, the battery may be damaged due to an excessively high ambient temperature, and the battery may not reach a working condition when the ambient temperature is excessively low.
In the embodiment of the application, the determined initial discharge coefficient of the battery can be corrected according to the ambient temperature, so that the current discharge coefficient can be determined more accurately.
And step 205, determining the current remaining mileage of the vehicle to be estimated according to the current discharge coefficient and the current remaining capacity of the battery.
And step 206, determining the current user of the vehicle according to the current operation data of the vehicle to be estimated.
Wherein the operational data may include at least one of: the running speed, the turning angle, the braking speed and the bearing capacity are not limited in the application.
For example, different users have their own driving habits when driving a vehicle.
For example, the user a and the user B who use the vehicle often. The user A generally has lower running speed and smaller turning speed, the vehicle running speed is more stable, the user B generally has higher running speed and relatively larger turning speed, and the vehicle running speed has larger change. And if the current running speed of the vehicle to be estimated is low and the running speed change is small, determining that the current user of the vehicle is the user A.
It should be noted that the user A, B and the operation data in the above example are only schematic illustrations, and are not intended to be limiting for determining the current user of the vehicle in the embodiment of the present application.
And step 207, correcting the current remaining mileage of the vehicle according to the historical use data of the current user.
The historical usage data of the user may include any relevant usage data such as a historical driving speed, a historical driving time, a historical driving record, and a historical driving route of the user, which is not limited in this application.
For example, the current user is user a, whose historical driving speed is low and stable, and if the battery can support the far remaining mileage according to the driving characteristics, the remaining mileage value determined at present may be relatively small, so that the remaining mileage value can be corrected to make the determined remaining mileage more accurate.
Or, the current user is user B, the historical driving speed of the user is high, the driving speed change is large, if according to the driving characteristics of the user, the remaining mileage value which can be supported by the battery is small, and the remaining mileage value which is determined at present may be relatively large, so that the remaining mileage can be corrected to make the determined remaining mileage more accurate, and therefore the user can timely cope with the subsequent situation, reduce the occurrence of accidents, and improve the use feeling of the user.
It should be noted that, the user A, B, the historical usage data, and the like in the above example are only examples, and cannot be used as a limitation for correcting the current remaining mileage of the vehicle in the embodiment of the present application.
It is understood that there are many ways to obtain historical usage data of the current user.
For example, when the user corresponds to the vehicle, the historical usage data associated with the vehicle is the current historical usage data of the user.
Or when a plurality of users use the same vehicle, the current user of the vehicle can be determined according to the current operation data of the vehicle, and then the historical use data can be obtained.
Or, for the vehicle which can be controlled by the application software, the current user can be determined by the user identifier in the application software of the currently controlled vehicle, and then the historical use data is acquired.
It should be noted that the foregoing examples are merely illustrative, and should not be taken as limitations on obtaining historical usage data of a user in the embodiments of the present application.
And step 208, acquiring the current destination of the vehicle.
There are various ways to obtain the current destination of the vehicle.
For example, the current destination of the vehicle may be determined based on navigation information of a user currently using the vehicle. For example, in the navigation system of the current user of the vehicle, the input navigation information is "AAA square", so that it can be determined that the current destination of the vehicle is "AAA square".
Or determining the current destination of the vehicle according to the historical use data of the current use user of the vehicle.
The historical usage data of the user may include a departure place, a departure time, a driving speed, a driving time, a destination, a driving route, and the like of the vehicle, which is not limited in the present application.
For example, according to the historical usage data of the current vehicle user, the user can be seen to travel for forty minutes from home to reach the company according to the route a at eight points every day. If the vehicle still starts from home at eight points today, the vehicle drives according to the route A, the current time is twenty eight points, and the vehicle continues to drive according to the route A, so that the current destination of the vehicle can be determined to be a company.
It should be noted that the above examples are only illustrative, and should not be taken as a limitation on the embodiment of the present application to obtain the current destination of the vehicle.
And step 209, sending an early warning message to the current user of the vehicle when the distance between the current position information and the destination is greater than the remaining mileage.
If the distance between the current position information of the vehicle and the destination is larger than the determined remaining mileage, the remaining capacity of the battery in the vehicle can only support the running of the remaining mileage, but the vehicle can not reach a farther destination, and the danger of the battery capacity exhaustion exists in the driving process, so that the warning message can be sent to the current user of the vehicle, the current user can be prepared in advance, and the journey can be planned reasonably.
And step 210, sending a vehicle driving suggestion to a current user of the vehicle when the distance between the current position information and the destination is less than or equal to the remaining mileage.
The vehicle driving advice may be any relevant advice that the vehicle can reduce the discharging speed to ensure that the vehicle can reach the destination, for example, the vehicle driving advice may be suitable driving speed, driving time and the like determined according to the remaining capacity of the battery, which is not limited in the present application.
For example, if the distance between the current position information of the vehicle and the destination is less than or equal to the determined remaining mileage, a vehicle driving advice, such as a preferred driving speed, may be sent to the user currently using the vehicle, so as to ensure that the user can reach the destination, thereby giving the user a good feeling of use.
According to the embodiment of the application, the current residual capacity of the battery in the vehicle to be estimated, the historical use data of the battery and the current position information of the vehicle are obtained, then the initial discharge coefficient of the battery can be determined according to the historical use data of the battery, and determining the current ambient temperature of the vehicle according to the current position information of the vehicle, further correcting the initial discharge coefficient to determine the current discharge coefficient of the battery, after the current remaining mileage of the vehicle to be estimated is determined according to the current discharge coefficient and the current remaining capacity of the battery, it is also possible to estimate the current operation data of the vehicle to be estimated and the historical use data of the current user, and correcting the current remaining mileage of the vehicle, and sending a corresponding message to the user according to the relationship between the current position information and the acquired distance between the current destination of the vehicle and the remaining mileage. Therefore, the remaining mileage of the vehicle to be estimated can be accurately determined through the acquired relevant data of the remaining electric quantity of the battery and the like, the environmental temperature, the destination and the like, the accuracy of determining the remaining mileage is improved, an accurate use suggestion is provided for a user through the distance relation between the remaining mileage and the current position and the destination, the mileage anxiety of the user can be effectively relieved, the time of the user is saved, the performance of the vehicle is improved, and the user experience is further improved.
