S3: judging whether to plan the charging pile into a navigation route or not according to the allowable power consumption per hundred kilometers and a preset lower limit value of the power consumption per hundred kilometers;
s4: if not, outputting a navigation route, and controlling the working mode of the sub-functions of each functional domain of the vehicle according to the allowable power consumption per hundred kilometers;
at this time, because the residual energy of the vehicle is enough to support the vehicle to reach the destination, and no charging operation is needed, the position of the charging pile is not needed to be considered when the navigation route is planned, and the optimal navigation route is planned according to the shortest driving time and the shortest distance based on the current position and the target position.

The vehicle can prestore the energy consumption of each sub-function in different working modes, after the allowed power consumption of each hundred kilometers of the vehicle is calculated, the priority is from low to high, the working modes are adjusted from super power saving to normal in sequence, wherein the total energy consumption of all the sub-functions after the working modes are adjusted is less than or equal to the allowed power consumption of each hundred kilometers.
In the embodiment of the invention, the priority can be preset for the sub-functions under each functional domain of the vehicle based on the influence degree of each sub-function on the normal running of the vehicle; for example, the sub-functions of the vehicle can be divided into three levels, one level, according to the degree of influence on the normal running of the vehicle: door control, vehicle light control, wiper control, window control, and the like; and (2) second stage: automatic parking, automatic exit, navigation functions and the like, and three stages are as follows: air conditioning control, lighting control, and the like. According to the allowed power consumption per hundred kilometers of the vehicle, the subfunction corresponding to the third-level priority is set to be in a super power-saving working mode, the subfunction corresponding to the second-level priority is set to be in a power-saving working mode, and the subfunction corresponding to the first-level priority is set to be in a normal working mode, so that after the working mode of the subfunction is adjusted, the energy consumption is reduced, the vehicle is ensured to be within the allowed power consumption per hundred kilometers, and meanwhile, the high-priority subfunction is preferentially ensured to work.

When the allowed power consumption per hundred kilometers is greater than or equal to a preset lower limit value of the power consumption per hundred kilometers, the vehicle needs to be considered to be charged, at the moment, a route planning model is established by taking the shortest driving time, the shortest driving distance and the lowest charging cost as targets, an optimal navigation route is screened out from a plurality of routes from the current position to the target position in a vehicle starting navigation mode, and the navigation route meets the following conditions: the charging pile has the advantages of shortest driving time, shortest driving distance, lowest charging cost and the way of charging. The route planning model can adopt a dynamic planning algorithm or directly call a related algorithm of a navigation system of the vehicle to plan the route.
For a vehicle traveling in a long distance, when the driving mileage is less than or equal to the target mileage of the vehicle and the allowed power consumption per hundred kilometers is greater than or equal to the preset lower limit value of the power consumption per hundred kilometers, the route planning of the charging pile is considered while the work mode of the sub-functions of each functional domain of the vehicle is adjusted, the route planning and the energy consumption management of a user are assisted, and the anxiety of the mileage of the long distance traveling in the new energy vehicle can be effectively relieved.
