Therefore, the driving route can be flexibly adjusted, the situation that the user searches for the driving route in the process of going to the charging place is avoided, and convenience of charging the vehicle by the user is improved.

In another possible implementation manner, the determining of the driving route information and the charging planning information of the vehicle on the driving route according to the driving destination information and the charging setting information includes, as shown in fig. 4:

s401, determining a plurality of candidate driving routes according to the driving destination information.

And determining a plurality of candidate driving routes according to the driving destination information input by the user, wherein the candidate driving routes can be shortest in use time, can be the shortest in traffic light quantity, and can be the best in road pavement.

On the basis of determining a plurality of candidate driving routes, charging planning information of each candidate driving route is determined according to charging setting information, such as charging times and charging facilities within a preset driving route range.

Illustratively, three candidate driving routes are determined according to the driving destination of the user, and according to the charging times input by the user being 1 time, the charging facility is searched for within a preset range of 5 km on the three candidate driving routes, and then a corresponding charging place is displayed on each candidate driving route.

And further displaying the determined driving route and charging planning information on a user interface.

Therefore, the charging facility information on each driving route can be displayed for the user, the user can conveniently and reasonably select the route according to the charging place, and the flexibility and convenience of charging the vehicle by the user are improved.

and determining running route information according to the running destination information, and determining charging planning information of the vehicle on a running route according to the weight value of the charging times, the weight value of the single-time charging time and the weight value of the working time of the internal combustion engine.

The charge planning information further comprises the charge times, a single charge time length value and an internal combustion engine working time length value, wherein the size relation among the charge times, the single charge time length value and the internal combustion engine working time length value accords with the size relation among the charge times option weight value, the single charge time length option weight value and the internal combustion engine working time length option weight value.

Specifically, the vehicle is provided with a weighted value of the charging time, the single charging time and the operating time of the internal combustion engine, for example, the values of the charging time, the single charging time and the operating time of the internal combustion engine in the vehicle are respectively 2,1 and 3, and then the weighted value of the charging time is: 2/(2 +1+ 3), namely the weight value of the charging times is 1/3; the time length weighted value of single charging is as follows: 1/(2 +1+ 3), namely the weight value of the time length of single charging is 1/6; the weighted value of the working time length of the internal combustion engine is as follows: 3/(2 +1+ 3), namely the weight value of the working time length of the internal combustion engine is 1/2.

Furthermore, the magnitude of the charging times, the single charging time length value and the working time length value of the internal combustion engine are all positively correlated with the magnitude of the corresponding weight values, and the larger the weight values are, the larger the proportion of the corresponding options is when the charging planning information of the vehicle on the driving route is determined. For example, the charging number weight T1 is 1/3 and the charging number weight T2 is 1/2,1/3 is smaller than 1/2, and the charging number Y1 is smaller than the charging number Y2 in the charging schedule information determined based on the charging number weight T1 when the travel destination information is the same than the charging schedule information determined based on the charging number weight T2. Similarly, the larger the weighted value of the single charging time length is, the longer the determined single charging time length value is; the larger the weight value of the working time length of the internal combustion engine is, the longer the determined working time length of the internal combustion engine is.

Optionally, the acquiring the charge setting information of the vehicle includes: acquiring the weighted values input by a user aiming at a charging time option, a single charging time option and an internal combustion engine working time option;

Optionally, weights among any charging options are calculated according to input values of the user on the weight options of the charging times, the input values of the weight options of the single-charging time period and the input values of the weight options of the internal combustion engine working time period, and further, in combination with a residual charge threshold and a total power consumption amount, for all charging facilities and total power consumption amounts on a driving route, based on the principle that the starting time period of the internal combustion engine is as short as possible and the charging times and the single-charging time period are met, a place where the charging facility for charging the vehicle is located is selected, for example, for six charging places on the driving route, the distance between AB is far greater than EF, and in the case that the charging times are 5, five charging places A, B, C, D and E are preferentially selected instead of the five charging places A, C, D, E and F, so as to reduce the starting time period of the internal combustion engine. In a specific implementation, each charging location selection meeting the charging times is determined from all the chargeable locations, a plurality of charging location sets are obtained, the total starting time length of the internal combustion engine under each charging location selection is calculated, and the charging location with the minimum total starting time length of the internal combustion engine is selected as the charging location in the finally determined charging planning information.

For example, the weight value formula built in the vehicle for the charging times, the single charging time length and the internal combustion engine working time length is the charging times: single charging time: internal combustion engine operating time =2:1:3, the weight value of the vehicle built-in charging times is 2/(2 +1+ 3), namely 1/3; the weight value of the built-in single charging time length of the vehicle is 1/(2 +1+ 3), namely 1/6; the weight value of the working time length of the internal combustion engine in the vehicle is 3/(2 +1+ 3), namely 1/2; and determining the charging times input by the user according to the charging times option input value set by the user as 2, the single charging time option input value as 2 and the working time option input value of the internal combustion engine as 1: single charging time: if the weight values of the working time length of the internal combustion engine are respectively 2/5,2/5 and 1/5, determining that the combined weight value of the charging times is 2/5 of the charging times option input weight value multiplied by 1/3 of the built-in charging times of the vehicle, namely the combined weight value of the charging times is 2/15; the joint weight value of the single charging time is obtained by multiplying 2/5 of the input weight value of the single charging time option by 1/6 of the weight value of the built-in single charging time of the vehicle, namely the joint weight value of the single charging time is 1/15; the joint weight value of the working time length of the internal combustion engine is 1/5 of the input weight value of the working time length option of the internal combustion engine multiplied by 1/2 of the working time length of the internal combustion engine arranged in the vehicle, namely the joint weight value of the single charging time length is 1/10.

Illustratively, according to the charging time option input value set by the user as 2, the single charging time option input value as 2 and the internal combustion engine working time option input value as 1, the charging time input by the user is determined: the single charging time length: if the weight values of the working time length of the internal combustion engine are respectively 2/5,2/5 and 1/5, determining that the combined weight value of the number of times of charging is the charging number option, and multiplying the weight value by 2/5 by 1/3 of the number of times of charging built in the vehicle, namely the combined weight value of the number of times of charging is 2/15; the joint weight value of the single charging time is 2/5 times the weight value of the option input of the single charging time by 1/6 of the built-in single charging time of the vehicle, namely the joint weight value of the single charging time is 1/15; the combined weight value of the working time length of the internal combustion engine is 1/5 of the input weight value of the working time length option of the internal combustion engine multiplied by 1/2 of the working time length of the internal combustion engine arranged in the vehicle, namely the combined weight value of the single charging time length is 1/10. Further, according to a preset 20% remaining capacity threshold, the number of times of charging the vehicle in the driving route is planned to be 2 times, the single charging time is 60 minutes each time, the working time of the internal combustion engine may be 50 minutes, and the time for driving the vehicle to the destination is 400 minutes.

As another example, according to the user setting of the charge number option input value of 1, the single charge duration option input value of 2, and the engine operating duration option input value of 2, the charge number input by the user is determined: the single charging time length: if the weight values of the working time length of the internal combustion engine are respectively 1/5,2/5 and 2/5, determining that the combined weight value of the charging times is 1/5 of the charging times option input weight value multiplied by 1/3 of the built-in charging times of the vehicle, namely the combined weight value of the charging times is 1/15; the joint weight value of the single charging time is 2/5 times the weight value of the option input of the single charging time by 1/6 of the built-in single charging time of the vehicle, namely the joint weight value of the single charging time is 1/15; the combined weight value of the working time length of the internal combustion engine is 2/5 of the input weight value of the working time length option of the internal combustion engine and is multiplied by 1/2 of the working time length of the internal combustion engine arranged in the vehicle, namely the combined weight value of the single charging time length is 1/5. Further, according to a preset 20% remaining capacity threshold, the number of times of charging the vehicle in the driving route is planned to be 1, the single charging time is 60 minutes each time, the working time of the internal combustion engine may be 90 minutes, and the time for driving the vehicle to the destination is 340 minutes. It is worth noting that in this case, the vehicle power battery has a remaining capacity greater than the remaining capacity threshold. Compared with the previous example, the user sets the internal combustion engine working time options to be smaller, the charging times are more, and the time spent on reaching the destination is more, but the internal combustion engine working time is shorter, and the vehicle cost is lower. In the example, the charging times are less, the time spent on reaching the destination is less, and the user can reach the destination as soon as possible, but the internal combustion engine has longer working time and higher vehicle cost.

As another example, according to the charging number option input value set by the user as 2, the single-charging duration option input value as 1, and the internal combustion engine operating duration option input value as 2, the charging number input by the user is determined: the single charging time length: if the weight values of the working time length of the internal combustion engine are respectively 2/5,1/5 and 2/5, determining that the combined weight value of the charging times is the weight value of 2/5 times the weight value of 1/3 of the charging times in the vehicle when the charging times option is input, namely the combined weight value of the charging times is 2/15; the joint weight value of the single charging time is 1/5 of the input weight value of the single charging time option multiplied by 1/6 of the weight value of the built-in single charging time of the vehicle, namely the joint weight value of the single charging time is 1/30; the combined weight value of the working time length of the internal combustion engine is 2/5 of the input weight value of the working time length option of the internal combustion engine and is multiplied by 1/2 of the working time length of the internal combustion engine arranged in the vehicle, namely the combined weight value of the single charging time length is 1/5. Further, according to a preset 20% remaining capacity threshold value, the number of times of charging the vehicle in the driving route is planned to be 2, the single charging time is 40 minutes each time, the working time of the internal combustion engine may be 70 minutes, and the time for driving the vehicle to the destination is 320 minutes. At this time, compared to the first example, the time period of a single charge becomes short, the time taken to reach the destination is small, but the operating time of the internal combustion engine is long, and the vehicle cost is high; compared to the second example, the time taken to reach the destination is less, the internal combustion engine is less on-time, the vehicle cost is lower, but the number of charging times is greater, and the user has less time to break each time on the way.

Therefore, the charging times, the single charging time value and the internal combustion engine working time value in the running process can be determined according to the input value of the user and the information of the weight value built in the system. The charging setting information can be flexibly set, and then the running state of the vehicle can be flexibly controlled.

the travel mode information is determined by:

determining a driving distance of the vehicle from a first charging place to a second charging place on the driving route according to the driving route information and the charging place information, wherein the first charging place and the second charging place are any two adjacent charging places planned to charge the vehicle in the charging planning information;

Determining driving route information according to the driving destination, determining corresponding power consumption according to road information in the driving route, for example, calculating total power consumption of the vehicle for driving from the first charging place to the second charging place in a pure electric mode according to uphill information, downhill information and road congestion information, and further determining a driving mode of the vehicle according to residual power information of a power battery and the total power consumption. And if the residual electric quantity of the vehicle at the first charging place is larger than the total consumed electric quantity, setting the vehicle to run in an electric-only mode between the first charging place and the second charging place.

For example, the remaining capacity of the power battery at the first charging place is 60%, the total consumed capacity of the vehicle for running from the first charging place to the second charging place in the electric-only mode is 45%, the remaining capacity of the vehicle at the first charging place is 60% larger than the total consumed capacity of 45%, and the vehicle is set to run in the electric-only mode between the first charging place and the second charging place. Therefore, the working time of the internal combustion engine can be reduced, and the fuel consumption is saved.

And S505, if the residual electric quantity of the vehicle at the first charging place is larger than the total consumed electric quantity, setting the vehicle to run in a pure electric mode between the first charging place and the second charging place.
