And S20, controlling the engine to drive the generator to generate power when the vehicle-mounted storage battery is determined to need to be charged according to the electric quantity information.
After the electric quantity information of the vehicle-mounted storage battery is acquired, whether the vehicle-mounted storage battery needs to be charged or not is judged according to the electric quantity information, and if yes, the engine is controlled to drive the generator to generate electricity. It should be noted that, in some embodiments, if the SOC of the vehicle-mounted storage battery is included in the charge information, it is determined that the vehicle-mounted storage battery needs to be charged when the SOC of the vehicle-mounted storage battery is smaller than the first preset value. Wherein the first preset value is 85%, that is, when the SOC of the vehicle-mounted battery is less than 85%, it is determined that the vehicle-mounted battery needs to be charged.
And S30, judging whether the electric load of the whole vehicle is larger than the preset load according to the electric quantity information in the process of generating electricity by the generator.
After the generator is determined to need to be charged and the engine is controlled to drive the generator to charge, whether the electric load of the whole vehicle is larger than the preset load or not can be judged according to the electric quantity information in the process of generating electricity by the generator. It can be understood that the engine respectively works in two different working modes in the two situations that the electric load of the whole vehicle is greater than the preset load and the electric load of the whole vehicle is less than the preset load.
In some embodiments of the present invention, as shown in fig. 2, determining whether the electric load of the entire vehicle is greater than the preset load according to the electric quantity information includes: s201, judging whether the SOC of the vehicle-mounted storage battery is smaller than a second preset value or not, and judging whether the power supply voltage of the vehicle-mounted storage battery is smaller than a first preset voltage or not, wherein the second preset value is smaller than the first preset value.

If the SOC of the vehicle-mounted storage battery is judged to be not smaller than the second preset value, whether the power supply voltage of the vehicle-mounted storage battery is smaller than the first preset voltage or not is further judged, and if the power supply voltage of the vehicle-mounted storage battery is determined to be smaller than the first preset voltage, the electric load of the whole vehicle can be determined to be larger than the preset load.
In some embodiments of the invention, when the SOC of the vehicle-mounted storage battery is greater than or equal to the second preset value and the power supply voltage of the vehicle-mounted storage battery is greater than or equal to the first preset voltage, it is determined that the electrical load of the whole vehicle is less than or equal to the preset load, and the engine is controlled to keep running at the idle speed, so that the generator generates electricity according to the first output voltage and the first output current.
Specifically, when whether the electric load of the whole vehicle is larger than the preset load or not is judged according to the electric quantity information, if the SOC of the vehicle-mounted storage battery is judged to be smaller than the second preset value or not, the SOC of the vehicle-mounted storage battery is determined to be larger than or equal to the second preset value, and the power supply voltage of the vehicle-mounted storage battery is further determined to be larger than or equal to the first preset voltage, and the electric load of the whole vehicle is determined to be smaller than or equal to the preset load or not.

It can be understood that under the condition that the electric load of the whole vehicle is not larger than the preset load, when the generator generates electricity by using the first output voltage and the first output current, the electricity consumption of the current electric load can be met. Of course, the first output voltage and the first output current may be adjusted according to the magnitude of the preset load. It should be noted that, the second preset value is smaller than the first preset value, further, the second preset value is 50%, and the first preset voltage is 11.6V.
Alternatively, the first output voltage may be 13.6V and the first output current may be 40A, it being understood that the engine speed at idle conditions is 800 rpm.

Specifically, if it is determined that the electrical load of the whole vehicle is greater than the preset load, the engine can be controlled to increase the running speed in order to prevent the fluctuation of the engine speed and the increase of vibration, so as to increase the power generation amount of the generator and meet the use requirement of the electrical load.
In some embodiments of the present invention, when the electrical load of the entire vehicle is greater than the preset load, the generator generates power according to a second output voltage and a second output current, where the second output voltage is greater than the first output voltage, and the second output current is greater than the first output current.
Specifically, after it is determined that the electric load of the entire vehicle is greater than the preset load, the generator may be controlled to generate power according to the second output voltage and the second output current. It can be understood that under the condition that the electric load of the whole vehicle is greater than the preset load, when the generator generates electricity by using the second output voltage and the second output current, the electricity consumption of the current electric load can be met. Of course, the second output voltage and the second output current may also be adjusted according to the size of the actual load. Alternatively, the second output voltage may be 14.5V and the second output current may be 110A. It should be noted that in this embodiment, the engine speed may be increased to 1000 rpm.
In some embodiments of the invention, when the electric load of the whole vehicle is greater than the preset load, the output voltage value or the output current value can be limited only when the output current and the output voltage of the generator are controlled, so as to reduce the load output by the engine and avoid the shock problem of the engine. When the engine is in an idling working condition and the electric quantity information of the vehicle-mounted storage battery is acquired, the SOC of the vehicle-mounted storage battery or the power supply voltage of the vehicle-mounted storage battery can be acquired to judge the battery state, and then subsequent control is carried out, so that the load output by the engine is reduced, and the problem of engine shock is avoided. It should be noted that, for the specific implementation in this embodiment, reference may be made to the specific implementation of the vehicle engine idle speed power generation control method in the foregoing embodiment, and details are not described herein again.
In conclusion, the idling power generation control method for the vehicle engine can effectively avoid the problem of resonance caused by engine speed fluctuation and shock increase in the idling working condition, prolong the service life of the engine and improve user experience.
