Detailed Description

For better understanding of the technical solutions in the present specification, the following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings.

It should be understood that the described embodiments are only a few embodiments of the present specification, and not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step are within the scope of the present specification.

The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the specification. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

Fig. 1 is a flowchart of a method for controlling power generation of a range extender according to an embodiment of the present invention. The method may be used in a vehicle controller, as shown in fig. 1, and may include:

step 101, determining a first vehicle mode, wherein the first vehicle mode comprises a vehicle energy consumption mode and a range extender electricity generation tendency mode, and combinations of different vehicle energy consumption modes and range extender electricity generation tendency modes correspond to different vehicle modes.

In one implementation, a vehicle energy consumption mode includes: a priority power consumption mode, a priority fuel consumption mode, and an automatic mode. The power source of the range-extended electric vehicle mainly has two modes, one mode is used for providing power for a vehicle battery, and the other mode is used for providing power for a range extender. The range extender comprises a generator and a motor, the generator converts chemical energy into electric energy, the converted electric energy can charge a vehicle battery, and the electric energy can be converted into kinetic energy through the motor to provide power for the range-extended electric automobile. The priority consumption mode means that the vehicle controller will tend to use the vehicle battery to power the extended range electric vehicle first, and the priority consumption mode means that the vehicle controller will tend to use the extended range chemical energy to power the extended range electric vehicle first. The chemical energy can be energy released after gasoline and other fuels are combusted, and the specific fuel is determined according to the model of the extended range electric automobile. The automatic mode is that the vehicle controller automatically determines the power source according to the environment of the extended range electric vehicle.

In one implementation, a range extender power generation propensity mode includes: an economic efficiency priority mode and a power demand priority mode. The economic efficiency priority mode is that the range extender considers the economic efficiency firstly when generating electricity, and ensures that the energy is not wasted. The power demand priority mode is that the range extender can consider power supply firstly when generating power to ensure that the power of the vehicle is sufficient.

The user can autonomously select a vehicle mode, and the vehicle mode is a combination of a vehicle energy consumption mode and a range extender power generation tendency mode. For example, the user may select the priority power consumption mode and the economic efficiency priority mode, or may select the priority fuel consumption mode and the power demand priority mode. The vehicle controller determines a vehicle mode according to the selection information of the user.

Step 102, determining a first SOC level table associated with the first vehicle mode, where the first SOC level table defines a plurality of SOC intervals, and the plurality of SOC intervals correspond to different SOC value ranges respectively.

In the embodiment of the invention, the SOC of the vehicle battery reflects the remaining capacity of the vehicle battery, which is numerically the ratio of the remaining capacity of the vehicle battery to the total capacity of the vehicle battery, and is expressed by a percentage. The value range of the vehicle battery charging indicator is 0-100%, when the SOC is 0, the vehicle battery is completely discharged, and when the SOC is 100%, the vehicle battery is completely charged. The first SOC level table logically divides the SOC of the vehicle battery into a plurality of SOC intervals, each containing a continuous segment of SOC value, e.g., (10%, 15%) or (20%, 25%).

In one implementation, the plurality of SOC intervals defined by the first SOC level table include a safety interval and N SOC protection intervals, and a minimum SOC value of the safety interval is greater than a maximum SOC value in the N SOC protection intervals.

Specifically, the first SOC level table may include N SOC protection values, such as a first SOC protection value, a second SOC protection value, … …, and an nth SOC protection value, where the first SOC protection value to the nth SOC protection value are arranged in descending order of magnitude. The SOC protection interval is larger than the first SOC protection value and smaller than 100%, the SOC protection interval is smaller than the first SOC protection value and larger than the second SOC protection value, and the like, the SOC protection interval is smaller than the Nth SOC protection value and larger than 0. For example, when the first SOC protection value is 30% and the second SOC protection value is 20%, the safety interval is (30%, 100%), and the first protection interval is (20%, 30%).

And 103, acquiring the instantaneous SOC value of the vehicle battery in real time.

Specifically, the vehicle controller may obtain an instantaneous SOC value of the vehicle battery in real time, where the instantaneous SOC value reflects a remaining capacity of the vehicle battery at the present time.

And 104, determining a power generation mode of the range extender according to the SOC interval corresponding to the instantaneous SOC value, and driving the range extender to generate power according to the determined power generation mode.

In one implementation mode, when the instantaneous SOC value corresponds to an SOC protection interval, the power generation mode of the range extender is respectively a fixed-point power generation mode, a vehicle speed-based power generation mode and a power following power generation mode according to the SOC values of different SOC protection intervals from large to small, and each SOC protection interval corresponds to one power generation mode; and when the instantaneous SOC value corresponds to the safety interval, the range extender generates electricity in a fixed-point electricity generation mode.

In one implementation mode, the vehicle controller calculates a first weight coefficient of a fixed-point power generation mode, a second weight coefficient of a vehicle speed-based power generation mode and a third weight coefficient of a power following power generation mode according to an instantaneous SOC value; the power generation mode is based on the power generation mode and the corresponding weight coefficient, and the power generation mode is adopted to generate power together.

In the embodiment of the invention, the vehicle controller can select a single power generation mode or a comprehensive power generation mode. When the single power generation mode is selected, the vehicle controller determines an SOC interval corresponding to the instantaneous SOC value according to the instantaneous SOC value of the vehicle battery, and then determines a corresponding power generation mode according to the SOC interval. For example, the safety section and the first SOC protection section correspond to a fixed-point power generation system, the second SOC protection section corresponds to a vehicle speed-based power generation system, and the third SOC protection section to the nth SOC protection section correspond to a power follow-up power generation system.

When the comprehensive power generation mode is selected, the vehicle controller calculates a weight coefficient corresponding to each power generation mode according to the instantaneous SOC value of the vehicle battery, and simultaneously generates power by adopting the power generation modes together based on the power generation modes and the corresponding weight coefficients. When the instantaneous SOC value of the vehicle battery changes, the weight coefficient corresponding to each power generation manner also changes.

In the embodiment of the invention, a first vehicle mode is determined, and then a first SOC level table associated with the first vehicle mode is determined, wherein the first SOC level table defines a plurality of SOC intervals, and the plurality of SOC intervals respectively correspond to different SOC value ranges; the method comprises the steps of acquiring an instantaneous SOC value of a vehicle battery in real time, determining a power generation mode of a range extender according to an SOC interval corresponding to the instantaneous SOC value, and driving the range extender to generate power according to the determined power generation mode. By dividing the SOC interval, the power generation mode of the range extender is determined according to the SOC interval corresponding to the instantaneous SOC value of the vehicle battery, the vehicle power requirement is met, the battery electric quantity is sufficient, and meanwhile the running efficiency of the range extender is improved.

Fig. 2 is a flowchart of another method for controlling power generation of a range extender according to an embodiment of the present invention. As shown in fig. 2, may include:

step 201, acquiring an instantaneous SOC value of a vehicle battery in real time.

Step 202, determine whether the instantaneous SOC value is less than the starting SOC value.

The starting SOC value is usually set near the first SOC protection value, and the specific value is not limited. If the judgment result is no, returning to the step 201; if yes, go to step 203.

In step 203, the power generation mode of the range extender is determined.

And step 204, driving the range extender to generate power according to the corresponding power generation mode.

The starting SOC value of the vehicle battery is a limit value for driving the range extender to generate power by the vehicle controller, and when the instantaneous SOC value of the vehicle battery is smaller than the starting SOC value, the vehicle controller drives the range extender to generate power.

In step 205, the instantaneous SOC value of the vehicle battery is obtained in real time.

In step 206, it is determined whether the instantaneous SOC value is greater than the shutdown SOC value.

The shutdown SOC value needs to be greater than the startup SOC value, and the specific value is not limited under this condition. If yes, go to step 208; if the determination result is negative, go to step 207.

Step 207, determining whether the SOC interval corresponding to the instantaneous SOC value changes.

The instantaneous SOC value is a dynamic value and may change at any time. If yes, returning to step 203; if the determination result is negative, go to step 204.

And step 208, controlling the range extender to stop generating power.

The shutdown SOC value of the vehicle battery is a limit value for controlling the range extender to stop generating power by the vehicle controller, and when the instantaneous SOC value of the vehicle battery is larger than the shutdown SOC value, the vehicle controller controls the range extender to stop generating power.

For example, the user selects the second vehicle mode, the second SOC level table associated with the second vehicle mode includes three SOC protection values, the first SOC protection value is 30%, the second SOC protection value is 20%, the third SOC protection value is 30%, the start SOC value is 27%, the stop SOC value is 32%, the safety interval is (30%, 100%), the first SOC protection interval is (20%, 30%), the second SOC protection interval is (10%, 20%), and the third SOC protection interval is (0, 10%), wherein the safety interval and the first SOC protection interval correspond to a fixed-point power generation manner, the second SOC protection interval corresponds to a vehicle speed power generation manner, and the third SOC protection interval corresponds to a power follow-up power generation manner.

The vehicle controller obtains an instantaneous SOC value of a vehicle battery, when the instantaneous SOC value is smaller than 27%, the corresponding SOC interval is determined to be a first SOC protection interval, the corresponding power generation mode is determined to be fixed-point power generation, and the vehicle controller drives the range extender to generate power in the fixed-point power generation mode. After the fixed-point power generation mode is adopted for power generation, the instantaneous SOC value can still be continuously reduced, when the instantaneous SOC value is smaller than 20%, the vehicle controller determines the corresponding SOC interval as the second SOC protection interval again, determines the corresponding power generation mode as power generation based on the vehicle speed, and drives the range extender to generate power in the power generation mode based on the vehicle speed. If the instantaneous SOC value is still continuously reduced, when the instantaneous SOC value is less than 10%, the vehicle controller determines the corresponding SOC interval as a third SOC protection interval again, determines the corresponding power generation mode as power following power generation, and drives the range extender to generate power in the power following power generation mode. If the instantaneous SOC value is increased, when the instantaneous SOC value is larger than 10%, the vehicle controller drives the range extender to generate power again by adopting a power generation mode based on the vehicle speed. If the instantaneous SOC value is continuously increased, when the instantaneous SOC value exceeds 30%, the corresponding SOC interval is a safety interval, and at the moment, the vehicle controller still adopts a fixed-point power generation mode. When the instantaneous SOC value exceeds 32%, the vehicle controller controls the range extender to stop working. The change of the instantaneous SOC value is determined by the power generation power of the range extender and the power consumption of the range-extended electric automobile, and when the power generation power of the range extender is greater than the power consumption of the range-extended electric automobile, the instantaneous SOC value is increased; when the generated power of the range extender is smaller than the consumed power of the range-extended electric automobile or the range extender stops working, the instantaneous SOC value is reduced.
