when the residual electric quantity of the power battery 5 is less than or equal to 20%, switching to a parallel driving mode;
in the parallel drive mode, the engine 15 and the hybrid tank 16 are both used to drive the vehicle.
In addition, when 20% < the residual capacity of the power battery 5 < 80%, switching to a series range-extending mode;

In addition, the motors inside the mixing box 16 are marked EM1, and EM2, where the parameters of EM1 are: 55KW/160NM, the parameters of EM2 are: 70kw/155NM.
As shown in fig. 3, the graph of the universal characteristic of the engine 15 is shown with the left ordinate indicating the output torque of the engine 15 and the abscissa indicating the rotational speed of the engine 15. The operating points one, two and three correspond to the fuel consumption of the engine 15 in the universal characteristic map, respectively. And the circles corresponding to the first operating point and the second operating point refer to the minimum fuel economy, and then spread outwards, and gradually reach the fuel economy area after the third operating point. Specifically, when the running speed is equal to or less than 50km/h, the torque of the engine 15 is the first torque, corresponding to the first operating point in fig. 3; when the running speed is less than or equal to 80km/h and more than 50km/h, the torque of the engine 15 is the second torque, and corresponds to a second working point in the figure 3; when the running speed is > 80km/h, the torque of the engine 15 is the third torque, corresponding to the third operating point in fig. 3.

in the pure electric mode, the hybrid tank 16 is used to drive the vehicle.
S3: traveling to the destination based on the adjusted operation mode.
It should be noted that, the BMS feeds back the SOC value of the current battery to the HCU, the HCU judges to enter a hybrid mode according to the SOC value, and enters a series extended range mode when the battery power is 20% < SOC < 80%, and the engine 15 participates in power generation; the vehicle body electronic stabilization system 1 feeds back the collected current vehicle speed to the whole vehicle controller 2, and the whole vehicle controller 2 requires the engine controller 14 to control the rotating speed and torque of the engine 15 according to the vehicle speed, so that the engine 15 works in an economic zone with the optimal fuel consumption value; when the vehicle speed V is less than or equal to 50km/h, the engine 15 works at the working point 1; when the speed of the vehicle is 50km/h < V < 80km/h, the engine 15 works at the working point 2; when the vehicle speed V is more than or equal to 80km/h, the engine 15 works at the working point 3.
When the SOC is less than or equal to 20% or the power requirement of the whole vehicle is large, entering a parallel driving mode, and requiring the engine 15 to participate in driving by the HCU; when the SOC is more than or equal to 80%, the vehicle enters a pure electric mode and runs purely, the engine 15 does not work, and the power battery 5 supplies power to the hybrid electric tank 16, so that the hybrid electric tank 16 drives the vehicle to run through an internal motor.
The strategy of the hybrid electric vehicle power supply mainly develops around the characteristics of the engine 15 and the battery characteristics, and in a series range-increasing mode, the engine 15 is enabled to work in an economic area with an optimal fuel consumption value for a long time; when the SOC is less than or equal to 20%, the engine 15 is used as a main drive, long-term use is not recommended, the fuel economy is poor, and the service life of the battery is influenced to a certain extent; when the SOC is more than or equal to 80% in consideration of the service life of the battery, no power supplementing is recommended; the invention effectively improves the fuel economy of the series-parallel hybrid electric vehicle and prolongs the service life of the battery to a certain extent.
It should be further noted that when the power demand of the whole vehicle is high, the vehicle will also automatically switch into the parallel driving mode or the series range-increasing mode, for example, when the vehicle climbs a slope or accelerates, the engine 15 will be driven in parallel with the hybrid tank 16 due to the increase of torque or the increase of output power.
Although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
