Detailed Description
Embodiments of the present invention will be described in detail below, by way of example with reference to the accompanying drawings.
Fig. 1 is a flowchart of a vehicle power conservation control method according to an embodiment of the present invention. Referring to fig. 1, the vehicle power protection control method includes the steps of:
s1, acquiring the current residual quantity of the power battery and the target generated power of the generator.
S2, judging whether the current residual electric quantity exceeds a preset first default electric quantity value. And if the current residual electric quantity exceeds the preset default electric quantity value, executing step S3. And if the current residual electric quantity does not exceed the preset first default electric quantity value, executing step S4.
In this embodiment, the preset first default electric quantity value is different in different vehicle types, and the set values thereof are also different. Illustratively, when the vehicle model is: when the vehicle is a hybrid vehicle with a light truck, the preset first default electric quantity value is generally 25%. When the vehicle model is: in the case of a hybrid vehicle model of SUVs and sedans, the preset first default electric quantity value is typically 15%.
And S3, controlling the generator to continuously work at the target generated power.
And S4, increasing the target generated power, and controlling the generator to work according to the increased target generated power.
On the basis of the present embodiment, in other embodiments, the step of increasing the target generated power specifically includes:
the linear increase of the power is performed based on the target generated power.
According to the embodiment, the power generation power is linearly increased, so that smooth transition of the generator from the current working condition to the working condition after the power generation power is increased can be ensured, the phenomenon that vibration is severe due to sudden increase of power output of the generator is avoided, the NVH effect of the hybrid power assembly is reduced, and the phenomenon that the service life of the generator is shortened due to frequent power surge is avoided.
On the basis of the present embodiment, in other embodiments, the step of performing the linear increase of the power based on the target generated power specifically includes:
the linear increase is performed according to the target generated power (1+C), wherein C is a positive pure fraction.
On the basis of the embodiment, in other embodiments, 0.1 < C < 0.3.
According to the embodiment, by arranging the C, the power of the generator is intelligently controlled to be increased in order, the control intelligence is improved, and the control complexity is reduced.
In this embodiment, if the current remaining power does not exceed the preset first default power value, the target generated power is increased, so as to avoid further decrease of the remaining power of the power battery, ensure that the remaining power of the power battery is maintained at about the preset first default power value, and maintain the overall performance of the hybrid power system in a better state when the power value of the power battery is maintained above the preset first default power value, so that the power battery can be prevented from being used for a long time under the condition of too low power, resulting in shortening the service life of the power battery, and also prevent the power battery from being unable to provide instantaneous driving power for the vehicle under the condition of too low power, thereby affecting the hundred kilometers acceleration performance of the hybrid power system.
In order to avoid the increase of the generated power beyond the rated generated power of the generator, in other embodiments, step S4 includes:
s41, increasing the target generation power.
S42, determining a smaller value of the increased target power and the preset rated power and taking the smaller value as the first regulation power.
S43, controlling the generator to work according to the first regulation and control generated power.
The embodiment determines the smaller value of the increased target power generation and the preset rated power generation and takes the smaller value as the first regulation power generation power, so that the first regulation power generation power is prevented from exceeding the preset rated power generation power of the generator, the generator cannot work for a long time exceeding the preset rated power generation power, the service life of the generator is prolonged, and the problem that when the generator works exceeding the preset rated power generation power, the generator vibrates severely, so that the NVH performance of the whole hybrid power system is reduced is avoided.
In the case of increasing the generated power, the remaining power is not maintained, and therefore, in other embodiments, after step S4, the method further includes:
s10, after a preset time period is set, the first regulating and controlling residual electric quantity of the power battery is obtained again.
S11, judging whether the first regulation residual electric quantity exceeds a preset second default electric quantity value or not, wherein the preset second default electric quantity value is smaller than the preset first default electric quantity value. When the first regulated residual power exceeds the preset second default power value, step S12 is executed. And when the first regulated residual electric quantity does not exceed the preset second default electric quantity value, executing step S13.
In this embodiment, the preset second default electric quantity value < the preset first default electric quantity value. The second default electric quantity value is preset in different vehicle types, and the set values are also different. Illustratively, when the vehicle model is: when the vehicle is a hybrid vehicle of a light truck, the preset first default electric quantity value is generally 15%. When the vehicle model is: when the SUV and the sedan are in a hybrid vehicle type, the first default electric quantity value is preset to be 10 percent.

In the present embodiment, illustratively, the first 3S of the current time is retrieved, the actual power generated for each second, and the average value is calculated from the actual power generated for each second.
And S14, controlling the driving power of the driving motor not to exceed the actual average power generation power, and controlling the generator to work with the second regulation power generation power, wherein the second regulation power generation power=the first regulation power generation power (1+Cmax).
In this embodiment, under the condition of increasing the generated power, the remaining power is still not maintained, and then a second power-saving strategy is executed, that is: the power generator is controlled to work with the second regulated power generation, the average value of the power generation power in the past 3S is adopted to limit the driving power, and on the basis of meeting the driving power, the difference power between the second regulated power generation power and the actual power generation power is used for charging the power battery, so that the continuous decline of the residual electric quantity can be effectively avoided, and the power-preserving capacity of the whole hybrid power system is improved.
In the case where the upper limit value of the driving power is limited by the actual generated power, the remaining power is not maintained, and therefore, in other embodiments, after step S14, the method further includes:
s20, after a preset time period is set, the second regulating and controlling residual electric quantity of the power battery is obtained again.
S21, judging whether the second regulation residual electric quantity exceeds a preset third default electric quantity value or not, wherein the preset third default electric quantity value is smaller than the preset second default electric quantity value. When the second regulated residual power exceeds the preset third default power value, step S22 is executed. And when the second regulated residual electric quantity does not exceed the preset third default electric quantity value, executing step S23.
In this embodiment, the third default electric quantity value is preset < the second default electric quantity value. The third default electric quantity value is preset in different vehicle types, and the set values are also different. Illustratively, when the vehicle model is: when the vehicle is a hybrid vehicle with a light truck, the preset first default electric quantity value is generally 10%. When the vehicle model is: in the case of a hybrid vehicle model of SUVs and sedans, the preset first default electric quantity value is typically 7%.
S22, controlling the driving power of the driving motor not to exceed the actual average power generation power, and controlling the generator to work with the second regulation power generation power.
S23, the actual power generation power of a plurality of time periods before the current moment is called, and the actual average power generation power is obtained according to the actual power generation power of the plurality of time periods.
And S24, controlling the driving power of the driving motor not to exceed the actual average generated power B, and controlling the generator to work with the third regulated generated power, wherein the third regulated generated power=the second regulated generated power (1+Cmax), and 0 < B < 1.
On the basis of the embodiment, in other embodiments, 0.6 < B < 0.8.
In this embodiment, when the energy of the generator is used for both driving and generating, the optimal ratio in the industry is: driving energy: power generation energy=4: 3, namely: 75% of energy is used for driving, 25% of energy is used for generating electricity, so that driving requirements can be guaranteed, and defects that electric quantity is seriously lost and is difficult to hold can be avoided, therefore, the value B of the embodiment is preferably as follows: b is more than 0.6 and less than 0.8.
In this embodiment, when the actual generated power limits the upper limit value of the driving power, the remaining power is still not maintained, and then a third power saving strategy is executed, that is: the power generator is controlled to work by the third regulation and control power generation, the average value of the power generation power in the past 3S is adopted to limit the driving power, and on the basis of meeting the driving power demand, even if the actual power generation power is used for charging the power battery, the residual electric quantity is restrained from increasing and decreasing from the source, the continuous decrease of the residual electric quantity can be effectively avoided, and the power retention capacity of the whole hybrid power system is improved.
