[0053] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0054] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0055] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0056] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0057] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0058] Reference Figure 1 , Figure 1 1 is a flow chart of a range extender environment adaptive power generation compensation control method provided by the present invention, to illustrate a specific embodiment of a range extender environment adaptive power generation compensation control method provided by the present invention, including:

[0059] Obtain current power conservation and driving conditions;

[0060] Calculate the power generation compensation coefficient according to driving conditions;

[0061] The power generation compensation coefficient is multiplied by the current power conservation power to calculate the power generation output value;

[0062] Obtain a universal characteristic diagram of the engine of the range extender, and randomly select two points in the innermost circle area of ​​the universal characteristic diagram to calculate the engine speed command;

[0063] Calculating an engine torque command based on a power generation output value and an engine speed command;

[0064] The engine is driven according to the engine speed command and the engine torque command.

[0065] It is understandable that in Figure 1The current power conservation power is only indicated after considering NVH. NVH is the abbreviation of noise, vibration and harshness. This is a comprehensive issue to measure the quality of automobile manufacturing. It gives the most direct and superficial feeling to car users. Of course, it is not limited to this. The current power conservation power can also be just the sum of the forced power generation power, accessory power consumption power and driving demand power. Figure 1 It is only indicated that the power generation compensation coefficient is calculated by the sub-compensation coefficient of the battery cell temperature, the sub-compensation coefficient of the uphill slope, the sub-compensation coefficient of the plateau environmental conditions and the sub-compensation coefficient of the throttle conditions. Of course, it is not limited to this. The specific sub-compensation coefficient used in the calculation of the power generation compensation coefficient can be adjusted according to actual needs. This embodiment does not impose specific restrictions on this. In this embodiment, the operating parameters in the innermost area of ​​the universal characteristic diagram can make the engine have good power and economy. Therefore, two points in the innermost area of ​​the universal characteristic diagram are randomly selected to calculate the speed as the engine speed command. Of course, referring to Figure 1 After obtaining the engine power output value, the preferred speed range can be found through the line graph of engine speed and power, and the speed can be randomly selected as the engine speed command within the preferred speed range. The line graph of speed and power is obtained by converting the universal characteristic graph. In this embodiment, for a known engine power output value, the method of selecting the engine speed is not specifically limited, and it only needs to be able to make the engine have good power and economy.

[0066] The present embodiment provides a range extender environment adaptive power generation compensation control method, including: obtaining the current power and driving conditions; calculating the power generation compensation coefficient according to the driving conditions; multiplying the power generation compensation coefficient with the current power to calculate the power generation output value; obtaining the universal characteristic diagram of the engine of the range extender, randomly selecting two points in the innermost circle area of ​​the universal characteristic diagram to calculate the engine speed command; calculating the engine torque command according to the power generation output value and the engine speed command; driving the engine according to the engine speed command and the engine torque command. By calculating the power generation output value by considering the driving conditions, the speed and torque are determined by using the compensated power generation output value, thereby driving the engine of the range extender, so that the range extender can still have good power performance and power conservation performance under special driving conditions. In the innermost circle area of ​​the universal characteristic diagram, two points are randomly selected to calculate the engine speed command, so that the engine can have good economic performance while ensuring good power performance.

[0067] In some optional embodiments, obtaining the current power conservation power includes:

[0068] Obtaining the forced power generation, accessory power consumption and driving demand power, and adding the forced power generation, accessory power consumption and driving demand power to obtain the total power generation;

[0069] The current vehicle speed is obtained, and NVH limit is performed on the aggregated power generation according to the current vehicle speed to obtain the current power conservation power.

[0070] It is understandable that when the vehicle is at a low speed, the noise mainly comes from the engine, and the engine at a low speed generally requires a relatively large power to help the vehicle run, which leads to a poor driving experience for the driver at a low speed due to the noise. The NVH limit is applied to the total power generation. The lower the current speed, the lower the NVH limit value, and the lower the current power conservation power after considering NVH, so as to achieve a balance between the vehicle speed and the noise felt by the driver and improve the user experience.

[0071] In some optional embodiments, continue to refer to Figure 1 , calculate the power generation compensation coefficient according to the driving conditions, including:

[0072] The driving condition includes at least one sub-driving condition, and a sub-compensation coefficient corresponding to the sub-driving condition is calculated;

[0073] The power generation compensation coefficient is obtained by multiplying all the sub-compensation coefficients.

[0074] It is understandable that the battery cell temperature, uphill slope, plateau environmental conditions and throttle conditions will greatly affect the power generation under special circumstances. The power generation output value is calculated taking into account the driving conditions. Under special circumstances, such as full throttle and ramp, the power generation of the range extender is increased by 20%-50%, and when multiple sub-driving conditions occur at the same time, there is a superposition effect. Under non-special circumstances, the range extender generates power normally without abnormalities.

[0075] In some optional embodiments, referring to Figure 2 , Figure 2 It is a trend chart of the sub-compensation coefficient corresponding to the battery cell temperature, and calculates the sub-compensation coefficient corresponding to the sub-driving condition, including:

[0076] If the sub-driving condition is the battery cell temperature, the corresponding sub-compensation coefficient is calculated as follows:

[0077]

[0078] Among them, y is the sub-compensation coefficient corresponding to the battery cell temperature, x is the battery cell temperature, a is the first coefficient, and b is the first correction term.

[0079] It is understandable that in this embodiment, the situation is divided based on the cell temperature of 5°C. Of course, it is not limited to this and can be divided according to actual needs. When the cell temperature is greater than 5°C, the influence of the cell temperature is small, and a fixed value can be used as the sub-compensation coefficient corresponding to the cell temperature. When the cell temperature is less than or equal to 5°C, as the cell temperature gradually decreases, the influence of the cell temperature gradually increases, and the sub-compensation coefficient corresponding to the cell temperature needs to be gradually increased. In this special case, when the battery discharge capacity decreases, the vehicle's power and power retention capacity are improved.

[0080] Specifically, this embodiment provides a set of specific values ​​of the battery cell temperature and the corresponding sub-compensation coefficient, refer to Table 1:

[0081] Table 1. Cell temperature and its corresponding sub-compensation coefficient

[0082] Cell temperature / ℃ Sub-compensation coefficient corresponding to the cell temperature 1 -30 1.70 2 -25 1.60 3 -20 1.50 4 -15 1.40 5 -10 1.30 6 -5 1.20 7 0 1.10 8 5 1 9 10 1 10 15 1

[0083] In some optional embodiments, continue to refer to Figure 2 , calculate the sub-compensation coefficient corresponding to the sub-driving condition, including:

[0084] If the sub-driving condition is the battery cell temperature, the corresponding sub-compensation coefficient is calculated as follows:

[0085]

[0086] Among them, y is the sub-compensation coefficient corresponding to the battery cell temperature, x is the battery cell temperature, a is the first coefficient and a<0, and b is the first correction term.

[0087] It can be understood that in this embodiment, the battery cell temperature is divided into -30°C and 5°C.

[0088] Of course, it is not limited to this, and can be divided according to actual needs. When the cell temperature is greater than 5°C, the influence of the cell temperature is small, and a fixed value can be used as the sub-compensation coefficient corresponding to the cell temperature. When the cell temperature is in the range of -30°C to 5°C, as the cell temperature gradually decreases, the influence of the cell temperature gradually increases, and the sub-compensation coefficient corresponding to the cell temperature needs to be gradually increased. When the cell temperature is less than -30°C, the influence of the cell temperature is less than the influence of the cell temperature in the range of -30°C to 5°C. The sub-compensation coefficient corresponding to the cell temperature less than -30°C can be used. In this special case, when the battery discharge capacity decreases, the vehicle's power and power retention capacity can be improved.

[0089] In some optional embodiments, referring to Figure 3 , Figure 3 It is a trend chart of the sub-compensation coefficient corresponding to the uphill slope, and calculates the sub-compensation coefficient corresponding to the sub-driving condition, including:

[0090] If the sub-driving condition is an uphill slope, the corresponding sub-compensation coefficient is calculated as follows:

[0091]

[0092] Among them, m is the sub-compensation coefficient corresponding to the uphill slope, n is the slope percentage, c is the second coefficient and c>0, and d is the second correction term.

[0093] It is understandable that in this embodiment, the situation is divided based on the slope percentage of 20%. Of course, it is not limited to this and can be divided according to actual needs. When the slope percentage range is 0-20%, during the vehicle's uphill process, as the slope percentage increases, the power generation compensation coefficient of the range extender needs to be gradually increased. In this special case, when the driving power is too large, the vehicle's power and power conservation capabilities are improved.

[0094] When the slope percentage is 20%, the influence of the uphill slope changes less than the influence of the slope percentage within the range of 0-20%, and the sub-compensation coefficient corresponding to the slope percentage of 20% can be used.

[0095] Specifically, this embodiment provides a set of specific values ​​of uphill slope and its corresponding sub-compensation coefficient, refer to Table 2:

[0096] Table 2. Uphill slope and its corresponding sub-compensation coefficient table

[0097] Slope percentage / % Sub-compensation coefficient corresponding to uphill slope 1 0 1 2 5 1.10 3 10 1.20 4 15 1.30 5 20 1.40 6 25 1.40 7 30 1.40 8 40 1.40

[0098] In some optional embodiments, referring to Figure 4 , Figure 4 It is a trend chart of the sub-compensation coefficient corresponding to the plateau environmental conditions, and calculates the sub-compensation coefficient corresponding to the sub-driving conditions, including:

[0099] If the sub-driving operating condition is a plateau environmental condition, obtain the current atmospheric pressure, current air temperature and plateau environmental condition compensation table;

[0100] According to the current atmospheric pressure and the current air temperature, the plateau environmental condition compensation table is queried to obtain the sub-compensation coefficient corresponding to the plateau environmental condition.

[0101] It is understandable that in plateau environmental conditions, altitude affects air temperature and atmospheric pressure. The higher the altitude, the lower the air temperature and the lower the atmospheric pressure. When the vehicle is in a plateau scene, as the atmospheric pressure increases, the power generation compensation coefficient of the range extender needs to be gradually increased. As the air temperature decreases, the power generation compensation coefficient of the range extender needs to be gradually increased. In this special case, when the engine power is reduced, the vehicle's power and power conservation capabilities are improved.

[0102] Specifically, refer to Figure 4 , a trend graph of the sub-compensation coefficients corresponding to the plateau environmental conditions and a plateau environmental conditions compensation table can be generated by field testing in plateau scenes. A plateau environmental conditions compensation table is shown in Table 3:

[0103] Table 3. Plateau environmental conditions compensation table

[0104]

[0105] Table 3. Plateau environmental conditions compensation table

[0106]

[0107] In some optional embodiments, referring to Figure 5 , Figure 5 It is a trend chart of the sub-compensation coefficient corresponding to the throttle condition, and calculates the sub-compensation coefficient corresponding to the sub-driving condition, including:

[0108] If the sub-driving condition is a throttle condition, obtain the current accelerator pedal opening, the current SOC charging coefficient and the throttle compensation table;

[0109] The throttle compensation table is queried according to the current accelerator pedal opening and the current SOC charging coefficient to obtain the sub-compensation coefficient corresponding to the throttle condition.

[0110] It can be understood that the throttle conditions are affected by two factors: SOC and accelerator pedal opening. When the vehicle is operating in a large throttle condition, as the throttle opening increases, the power generation compensation coefficient of the range extender needs to be gradually increased. As the SOC decreases, the power generation compensation coefficient of the range extender needs to be gradually increased. In this special case, when the driving power is too large, the vehicle's power and power conservation capabilities can be improved.

[0111] Specifically, refer to Figure 5 , can be tested in the field under throttle conditions, so as to generate a trend diagram of the sub-compensation coefficients corresponding to the throttle conditions and a throttle compensation table, a throttle compensation table refers to Table 4:

[0112] Table 4. Throttle compensation table

[0113]

[0114] Table 4. Throttle compensation table

[0115]

[0116] In some optional embodiments, referring to Figure 6 , Figure 6 It is a trend chart of the correction of the sub-compensation coefficient corresponding to the throttle condition, and also includes:

[0117] Get the current vehicle speed and throttle compensation correction table;

[0118] According to the sub-compensation coefficient corresponding to the throttle condition and the current vehicle speed, the throttle compensation correction table is searched to obtain the correction value of the sub-compensation coefficient corresponding to the throttle condition;

[0119] The correction value is used to replace the sub-compensation coefficient corresponding to the throttle condition.

[0120] It can be understood that the sub-compensation coefficient corresponding to the throttle condition, which is affected by the two factors of the SOC charging coefficient and the accelerator pedal opening, can be increased by secondary adjustment with the vehicle speed in the low-speed section considering the NVH influence. When the vehicle speed is low, the sub-compensation coefficient corresponding to the throttle condition should be attenuated or derated. Therefore, this embodiment also provides a correction method for the sub-compensation coefficient corresponding to the throttle condition.

[0121] Specifically, refer to Figure 6 , a test considering the impact of NVH can be performed to generate a trend diagram of the sub-compensation coefficient correction corresponding to the throttle condition and a throttle correction table. A throttle correction table refers to Table 5:

[0122] Table 5. Throttle correction table

[0123]

[0124] Table 5. Throttle correction table

[0125]
