The terminal device 30 and the server 20 are connected in wireless communication, and the in-vehicle host computer 40 is connected in wireless communication with the in-vehicle terminal 10 and the server 20, respectively.
Referring to fig. 3, fig. 3 is a flowchart illustrating an implementation of a method for indicating charging of a vehicle according to an embodiment of the present application.
As shown in fig. 3, the method for indicating charging of a vehicle according to an embodiment of the present application may include S101 to S106, which are described in detail below:
In S101, the vehicle-mounted terminal transmits a first remaining power and a first range of the vehicle to the server.
In practical application, when a driver is using a vehicle, in order to avoid the vehicle from being anchored halfway due to insufficient electric quantity, the user experience is affected, and the driver can send a charging indication request to the vehicle-mounted terminal.
In this embodiment of the present application, the detection by the vehicle-mounted terminal of the charging instruction request sent by the driver may be: the driver is detected to trigger a preset operation. The preset operation may be determined according to actual requirements, which is not limited herein. The preset operation may be, for example, clicking a preset control, that is, if the vehicle-mounted terminal detects that the driver clicks the preset control, the preset operation is considered to be triggered, that is, it is considered that a charging indication request sent by the driver is detected.
Based on the above, the vehicle-mounted terminal can acquire the first residual capacity and the first endurance mileage of the power battery of the vehicle in real time after detecting the charging indication request, and send the first residual capacity and the first endurance mileage to the server.
In S102, the server receives a first remaining power and a first endurance mileage sent by the vehicle-mounted terminal.
In this embodiment of the present application, after receiving the first remaining power and the first range sent by the vehicle-mounted terminal, the server may compare the first remaining power with a first threshold, and compare the first range with a second threshold. The first threshold and the second threshold may be set according to actual needs, and are not limited herein.
In practical application, since the range of the vehicle is related to the current electric quantity of the vehicle and the range of the vehicle under the same electric quantity is different in different environments (such as seasons, summer or winter), the server can set the second threshold according to the first threshold and the environmental information of the vehicle.
In one embodiment of the present application, when the server detects that the first remaining power is less than or equal to the first threshold and the first endurance mileage is less than or equal to the second threshold, the server may execute steps S103 to S105, and the vehicle-mounted terminal may execute step S106.
In another embodiment of the present application, when the server detects that the first remaining power is greater than the first threshold, or the first range is greater than the second threshold, it indicates that the vehicle does not need to be charged at this time, and therefore, the vehicle-mounted terminal may continue to acquire the first remaining power and the first range in real time.
In S103, if the server detects that the first remaining power is less than or equal to a first threshold and the first range is less than or equal to a second threshold, the server obtains current location information of the vehicle.
In this embodiment of the present application, when the server detects that the first remaining power is less than or equal to the first threshold value and the first endurance mileage is less than or equal to the second threshold value, it indicates that the power of the vehicle is insufficient at this time and the endurance mileage is shorter, so, in order to avoid that the vehicle cannot continue to travel to the destination due to the fact that the power is insufficient and half-way is anchored, the server may acquire the current position information of the vehicle.
The current position information of the vehicle may be longitude and latitude coordinates where the vehicle is currently located.
The current finger server detects the moment when the first residual electric quantity is smaller than or equal to a first threshold value and the first endurance mileage is smaller than or equal to a second threshold value.
In an embodiment of the present application, in order to further improve user experience, avoid unnecessary charging reminding, after detecting that the first remaining power is less than or equal to a first threshold and the first endurance mileage is less than or equal to a second threshold, the server may specifically obtain current location information of the vehicle through steps S201 to S202 shown in fig. 4, which is described in detail as follows:
in S201, historical charging information of the vehicle is acquired; the history charging information records a reference amount of electricity by which the driver charges the vehicle in a history period of time.
In S202, if the first remaining power is less than or equal to the reference power, current location information of the vehicle is obtained.
It should be noted that, the historical time period may be set according to actual needs, which is not limited herein, and the historical time period may be any time period before the server receives the first remaining power and the first endurance mileage sent by the vehicle-mounted terminal, and in order to ensure the validity of the historical charging information, the historical time period may be 30 days before the server receives the first remaining power and the first endurance mileage sent by the vehicle-mounted terminal.
The reference electric quantity is used for describing the residual electric quantity of a driver when the vehicle is charged at a historical charging place sent by the server in a historical time period.
In this embodiment, after obtaining the historical charging information of the vehicle, the server may extract the reference electric quantity from the historical charging information, and compare the reference electric quantity with the first remaining electric quantity.
In one embodiment of the present application, when the server detects that the first remaining power is less than or equal to the reference power, it indicates that the power of the vehicle at this time has reached the power when the driver determines that the vehicle needs to be charged, and therefore, the server may acquire the current position information of the vehicle.
In another embodiment of the present application, when the server detects that the first remaining power is greater than the reference power, it indicates that the power of the vehicle at this time does not reach the power when the driver determines that the vehicle needs to be charged, so, in order to improve the user experience, the server may continue to execute steps S102 to S103 until the first remaining power is less than or equal to the reference power.
In S104, the server determines a charging location matching the vehicle according to the current location information.
In the embodiment of the application, after determining the current position information of the vehicle, the server can determine the charging place matched with the vehicle according to the current position information of the vehicle in order to ensure that the vehicle can be charged in time and avoid the vehicle from being anchored halfway.
In one embodiment of the present application, the server may search for whether a charging pile exists in a circular area formed by taking the current position information of the vehicle as a center and taking the first preset distance as a radius, and determine the position of the charging pile as a charging location matched with the vehicle. The first preset distance may be set according to actual needs, which is not limited herein.
The charging site may be one or a plurality of charging sites.
In another embodiment of the present application, in order to accurately determine a charging location matched with a vehicle to further improve a charging success rate of the vehicle, the server may determine the charging location matched with the vehicle through S301 to S303 as shown in fig. 5, which is described in detail as follows:
in S301, a charging range area matching the vehicle is determined according to the current position information.
In one embodiment of the present application, the server may determine a circular area configured with the current position information of the vehicle as a center and the second preset distance as a radius as a charging range area matched with the vehicle. The second preset distance may be set according to actual needs, which is not limited herein.
In another embodiment of the present application, in order to further improve the charging success rate, to avoid the vehicle from being anchored in the process of traveling to the charging site, the server may determine the charging range area matched with the vehicle according to the current location information, the first remaining power and the first endurance mileage of the vehicle.
In S302, environmental information and configuration information of each charging pile provided in the charging range area are acquired.
In this embodiment, after determining a charging range area matched with a vehicle, the server needs to determine each charging pile existing in the charging range area, and acquire environment information and configuration information of each charging pile.
It should be noted that, the environmental information of each charging pile includes, but is not limited to: the size of the area in which it is located, whether it is being used, whether there are other vehicles waiting to be charged, etc.
Configuration information for each charging stake includes, but is not limited to: is suitable for vehicle types, faults and the like.
In S303, the charging location is determined according to the environment information and the configuration information.
In this embodiment, the server may determine, according to the environmental information and the configuration information of each charging pile, and the configuration information and the first remaining power of the vehicle, a charging pile that may charge the vehicle, and determine the position information of the charging pile as a charging location that matches the vehicle.
In S105, the server transmits the charging location to the in-vehicle terminal and/or a terminal device used by a driver of the vehicle.
In S106, the vehicle-mounted terminal receives the charging location transmitted by the server.
In this embodiment of the present application, after receiving the charging location sent by the server, the vehicle terminal may control the vehicle to travel to the charging location so as to charge the vehicle.
Specifically, after receiving the charging location sent by the server, the vehicle-mounted terminal may perform the following steps, in detail, to ensure that the vehicle can accurately reach the charging location, so as to further improve the charging success rate of the vehicle:
acquiring current position information of the vehicle;
determining a driving path of the vehicle according to the current position information and the charging place;
and controlling the vehicle to travel to the charging place according to the travel path.
In this embodiment, after receiving the charging location sent by the server, the vehicle-mounted terminal may determine a running path of the vehicle according to the current location information of the vehicle and the charging location, and control the vehicle to run to the charging location according to the running path, so as to charge the vehicle.
As can be seen from the above, in the method for indicating charging of a vehicle provided by the embodiment of the present application, the first remaining power and the first endurance mileage sent by the vehicle-mounted terminal of the vehicle are received; if the first residual electric quantity is smaller than or equal to a first threshold value and the first endurance mileage is smaller than or equal to a second threshold value, acquiring current position information of the vehicle; determining a charging place matched with the vehicle according to the current position information; the charging location is sent to the vehicle-mounted terminal and/or to a terminal device used by the driver of the vehicle. Compared with the prior art, the method needs the server to judge whether the vehicle needs to be charged or not by combining the first residual electric quantity and the first endurance mileage sent by the vehicle-mounted terminal, after the fact that the vehicle needs to be charged is determined, a charging place matched with the vehicle can be determined according to the current position information of the vehicle, and the charging place is sent to the vehicle-mounted terminal and/or terminal equipment so as to instruct the vehicle to travel to the charging place for charging. Due to the fact that the residual electric quantity and the endurance mileage of the vehicle are combined, the server can clearly determine the travel of the residual electric quantity of the vehicle, and therefore when the travel of the residual electric quantity of the vehicle is detected to be less, charging reminding can be carried out, the risk that the vehicle cannot arrive at a charging place in time for charging is reduced, and the charging success rate is improved.
In one embodiment of the present application, referring to fig. 6, in order to further improve the charging success rate of the vehicle and avoid the vehicle from being anchored halfway, the server may specifically execute steps S401 to S402 shown in fig. 6, which are described in detail as follows:
in S401, when it is detected that the vehicle does not reach the charging location, a second remaining power and a second range sent by the vehicle-mounted terminal are received.
In this embodiment, after the server sends the charging location to the vehicle-mounted terminal and/or the terminal device used by the driver, the running position of the vehicle may be obtained from the vehicle-mounted terminal in real time, so as to determine whether the vehicle reaches the charging location.
When the server detects that the vehicle does not reach the charging place, the server can receive the second residual electric quantity and the second endurance mileage sent by the vehicle-mounted terminal, compare the second residual electric quantity with a third threshold value and compare the second endurance mileage with a fourth threshold value. The third threshold and the fourth threshold may be set according to actual needs, and are not limited herein.
The third threshold value is smaller than the first threshold value, and the fourth threshold value is smaller than the second threshold value.
In one embodiment of the present application, the server may execute step S402 when detecting that the second remaining power is less than or equal to the third threshold and the second range is less than or equal to the fourth threshold.
In another embodiment of the present application, when the server detects that the second remaining power is greater than the third threshold or the second range is greater than the fourth threshold, it indicates that the driver does not need to be reminded of recharging at this time, and therefore, the server does not need to perform any steps.
In S402, if the second remaining power is less than or equal to the third threshold and the second range is less than or equal to the fourth threshold, the step of acquiring the current position information of the vehicle and the subsequent steps are performed back.
In this embodiment, when the server detects that the second remaining power is less than or equal to the third threshold and the second range is less than or equal to the fourth threshold, it indicates that the remaining power of the vehicle is seriously insufficient and the range is extremely short, so the server may return to executing steps S102 to S105 to update the charging location in real time and send the updated charging location to the vehicle-mounted terminal and/or the terminal device used by the driver.
As can be seen from the above, in the method for indicating charging of a vehicle provided in this embodiment, after the server sends the charging location to the vehicle-mounted terminal and/or the terminal device used by the driver, when detecting that the vehicle does not reach the charging location, the server receives the second remaining power and the second endurance mileage sent by the vehicle-mounted terminal; and when the second residual electric quantity is detected to be smaller than or equal to a third threshold value and the second endurance mileage is detected to be smaller than or equal to a fourth threshold value, returning to execute the step of acquiring the current position information of the vehicle and the subsequent steps so as to update the charging place in real time, and ensuring that the vehicle can arrive at a new charging place in time for charging, thereby improving the charging success rate of the vehicle.
Referring to fig. 7, fig. 7 is a flowchart illustrating an implementation of a method for indicating charging of a vehicle according to still another embodiment of the present application. Compared to the corresponding embodiment of fig. 3, the method for indicating the charging of the vehicle provided in this embodiment may include S501 to S509, which are described in detail below:
in S501, the terminal device sends charging alert information to the server.
In this embodiment, in order to improve user experience, a driver may set charging reminding information through a terminal device.
Wherein, the charging reminding information includes but is not limited to: a charge threshold and whether the charge indication function is on. The charge threshold value is used to describe the remaining charge of the vehicle set by the driver when charging is required.
In S502, the server receives the charging reminding information sent by the terminal device.
In S503, the server determines the first threshold according to the charging alert information.
In this embodiment, after receiving the charging reminding information, the server may extract the electric quantity threshold from the charging reminding information.
In one implementation of this embodiment, the server may directly determine the power threshold as the first threshold.
In another implementation of this embodiment, the server may determine the first threshold based on the power threshold and the threshold magnitude. The threshold amplitude may be set according to actual needs, and is not limited herein, and exemplary, the threshold amplitude may be set to 5%.
Based on this, in the present embodiment, the first threshold value=the electric quantity threshold value±5%.
In S504, the server sends an information acquisition request to the in-vehicle terminal when it detects that the vehicle has started and the charging instruction function of the vehicle has been turned on.
In this embodiment, after receiving the charging prompt information, the server may continue to determine whether the charging indication function of the vehicle is turned on from the charging prompt information.
The server may send an information acquisition request to the vehicle-mounted terminal when detecting that the charge indication function of the vehicle has been turned on and the vehicle has been started. The information acquisition request is used for requesting the vehicle-mounted terminal to send the residual electric quantity and the endurance mileage of the vehicle to the server.
In S505, the vehicle-mounted terminal receives the information acquisition request, and transmits the first remaining power and the first range to a server.
In S506, the server receives the first remaining power and the first endurance mileage sent by the vehicle-mounted terminal.
In S507, if the server detects that the first remaining power is less than or equal to a first threshold and the first range is less than or equal to a second threshold, the server obtains current location information of the vehicle.
In S508, the server determines a charging location matching the vehicle according to the current location information.
In S509, the server transmits the charging place to the in-vehicle terminal and/or a terminal device used by a driver of the vehicle.
S506 to S509 in this embodiment are the same as S102 to S105 in the embodiment corresponding to fig. 3, and specific reference is made to the description related to S102 to S105, which is not repeated here.
In S5010, the in-vehicle terminal transmits the charging place to the in-vehicle host.
In S5011, the in-vehicle host displays the charging place.
The number of charging sites is plural.
Based on this, in this embodiment, the in-vehicle host computer may display the above-described plurality of charging places on its own screen for selection by the driver.
In S5012, the in-vehicle host receives the selection information input by the driver.
In this embodiment, after the on-vehicle host displays the above-mentioned plurality of charging places on its own screen, the driver may click on any one of the charging places on the screen, that is, input selection information to the on-vehicle host.
In S5013, the in-vehicle host determines a charging position according to the selection information, and sends the charging position to the in-vehicle terminal.
In this embodiment, after receiving the selection information input by the driver, the on-vehicle host may extract the charging location selected by the driver from the selection information, and determine the charging location as the charging location.
In S5014, the in-vehicle terminal receives the charging position.
In this embodiment, after receiving the charging position sent by the server, the vehicle-mounted terminal may determine a running path of the vehicle according to the current position information of the vehicle and the charging position, and control the vehicle to run to the charging position according to the running path, so as to charge the vehicle.
As can be seen from the above, in the method for indicating charging of a vehicle provided in the present embodiment, the driver may set the charging reminding information through the terminal device, so that the server performs subsequent charging reminding according to the setting of the driver; meanwhile, only when the vehicle is started and the charging indication function of the vehicle is started, the server receives the first residual electric quantity and the first endurance mileage of the vehicle sent by the vehicle-mounted terminal and executes subsequent charging indication operation, so that user experience is improved.
In still another embodiment of the present application, after the server sends the charging places to the terminal device used by the driver of the vehicle, since the charging places are plural, the terminal device may display the plural charging places for the driver to select, so as to improve the user experience.
In this embodiment, the driver may click on any charging location on the display interface of the terminal device, that is, location information is input to the terminal device.
After receiving the location information input by the driver, the terminal device may extract a charging location selected by the driver from the location information and determine the charging location as a charging location.
In yet another embodiment of the present application, after determining the charging location, the terminal device may obtain a navigation path of the vehicle based on the charging location using a navigation system configured by the terminal device, so that the driver may control the vehicle to travel to the charging location according to the navigation path.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.
