Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
To facilitate understanding of the present invention, concepts related to the present invention are described below:
equivalent combustion: the combustion mode of air and natural gas combusted in the cylinder at the theoretical air-fuel ratio is controlled.
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
Referring to fig. 1, fig. 1 is a flowchart of a method of controlling a throttle according to an embodiment of the present invention. As shown in fig. 1, the throttle control method is specifically a natural gas internal combustion engine throttle control method, and can be applied to an ECU (Electronic Control Unit, engine controller), and includes the steps of:
s10, responding to a gear shifting instruction, and determining a gear shifting type.
In the embodiment of the invention, the gear shifting instruction can be determined by monitoring the gear shifting requirement of a user. After the shift command is obtained, a shift type of the AMT may be further determined, which may be an upshift or a downshift.
Specifically, the shift type may be determined by monitoring the current gear and the target gear. Referring to fig. 2, fig. 2 is a partial method flowchart of a throttle control method according to an embodiment of the present invention. As shown in fig. 2, step S10 "determine shift type" may employ the following steps:
s101, acquiring a current gear and a target gear.
S102, if the current gear is smaller than the target gear, determining that the gear shifting type is up-shifting.
S103, if the current gear is greater than the target gear, determining that the gear shift type is a downshift.
Specifically, in the embodiment of the present invention, during AMT gear shifting, the TCU (Transmission Control Unit, i.e., the automatic gearbox controller) may send the current gear and the target gear to the ECU through the CAN bus. In this regard, the ECU may determine whether the AMT shift type is upshift or downshift by comparing the current gear with the target gear. If the current gear is smaller than the target gear, the gear shifting type is up-shifting; if the current gear is greater than the target gear, the shift type is determined to be a downshift.
S20, acquiring the opening of an accelerator pedal, and determining the throttle valve compensation opening according to the gear shifting type and the opening of the accelerator pedal.
In the embodiment of the invention, after the gear shifting type is determined, the throttle pedal opening is collected in consideration of the driving requirement of a user, and then the throttle valve compensation opening matched with the throttle pedal opening under the gear shifting type is determined. Specific:
on the one hand, throttle valve compensation opening degrees corresponding to different throttle pedal opening degrees during upshift are calibrated in advance, and the corresponding relation is recorded into a corresponding mapping table. When the gear shifting type is determined to be the upshift, the throttle valve compensation opening corresponding to the opening of the accelerator pedal can be determined by inquiring the mapping table, so that the gear shifting quality and the dynamic property during the upshift are both considered. Of course, the throttle valve compensation opening degree is positively correlated with the accelerator pedal opening degree, that is, the larger the accelerator pedal opening degree is, the larger the throttle valve compensation opening degree is.
On the other hand, throttle valve compensation opening degrees corresponding to different throttle pedal opening degrees during downshift are calibrated in advance, and the corresponding relation is recorded into a corresponding mapping table. When the gear shifting type is determined to be the downshift, the throttle valve compensation opening corresponding to the opening of the accelerator pedal can be determined by inquiring the mapping table, so that the problem of poor speed regulation performance adaptability during the downshift is solved. Of course, the throttle valve compensation opening degree is positively correlated with the accelerator pedal opening degree, that is, the larger the accelerator pedal opening degree is, the larger the throttle valve compensation opening degree is.
And S30, controlling the throttle valve according to the throttle valve compensation opening degree.
In the embodiment of the invention, after the throttle valve compensation opening degree is determined, the throttle valve can be subjected to compensation control according to the throttle valve compensation opening degree. Therefore, throttle control under different gear shifting types is realized, gear shifting quality and dynamic property are improved, and gear shifting time is shortened.
In some scenarios, in order to accurately determine the throttle compensation opening degrees under different shift types, the step S20 "determine the throttle compensation opening degrees according to the shift type and the accelerator pedal opening degrees" may employ the following steps:
determining a first throttle compensation opening matched with the opening of the accelerator pedal under the condition that the gear shifting type is upshift; wherein the first throttle compensation opening is positively correlated with the accelerator pedal opening;
under the condition that the gear shifting type is the gear shifting, calculating the number of the gear shifting by utilizing the current gear shifting and the target gear shifting, and determining a matched second throttle valve compensation opening according to the number of the gear shifting and the opening of an accelerator pedal; wherein the second throttle valve compensation opening is positively correlated with the number of downshifts and positively correlated with the accelerator pedal opening.
In the embodiment of the invention, when the gear shifting type is upshift, the corresponding throttle valve compensation opening degree, namely the first throttle valve compensation opening degree, can be determined through the throttle pedal opening degree. The first throttle valve compensation opening degree is positively correlated with the accelerator pedal opening degree, namely, the stronger the driving requirement of a user is, the larger the accelerator pedal opening degree is, and the larger the first throttle valve compensation opening degree is.
In addition, considering the working mode of the gear box when the AMT is shifted up, the embodiment of the invention can also determine the first throttle valve compensation opening degree by combining the working mode of the gear box, so that the throttle valve control can adapt to different working modes of the gear box. Referring to fig. 3, fig. 3 is a flowchart of another part of the throttle control method according to the embodiment of the present invention. As shown in fig. 3, the step of "determining the first throttle compensation opening degree that matches the accelerator pedal opening degree" may employ the steps of:
s201, acquiring a working mode of the gearbox.
S202, determining a first throttle compensation opening matched with the opening of an accelerator pedal according to a working mode of the gearbox; the working mode of the gearbox comprises an economic mode and a power mode, and when the opening of the accelerator pedal is the same value, the value of the first throttle valve compensation opening in the economic mode is smaller than that in the power mode.
In the embodiment of the invention, when the AMT upshift is determined, the working mode of the gearbox can be further detected, and the working mode of the gearbox is an E/P mode, namely an Economy/Power mode, an Economy mode/Power mode. For the E mode (i.e., economy mode) and the P mode (i.e., power mode), the first throttle compensation opening during shift and throttle can be determined according to the throttle pedal opening in the different modes.
Table 1: data table of first throttle valve compensation opening corresponding to different throttle pedal opening in E mode
As shown in table 1, the data table records first throttle compensation opening degrees corresponding to different accelerator pedal opening degrees in the E mode.
Table 2: data table of first throttle valve compensation opening corresponding to different throttle pedal openings in P mode
As shown in table 2, the data table records therein the first throttle compensation opening degrees corresponding to the different accelerator pedal opening degrees in the P mode.
As can be seen from comparing tables 1 and 2, when the accelerator pedal opening is the same value, the value of the first throttle compensation opening in the E mode is smaller than that in the P mode. It should be noted that, the first throttle compensation opening degrees corresponding to different throttle pedal openings in the E mode and the P mode shown in table 1 and table 2 are only examples, and different values may be set in different scenes, which is not limited to the embodiment of the present invention.
Referring to fig. 4, fig. 4 is a schematic diagram of throttle valve compensation control during an AMT upshift according to an embodiment of the invention. As shown in fig. 4, the engine has three stages of torque clearing, speed regulation and torque returning during AMT upshift, and the throttle opening, the fuel injection amount, the engine torque output and the engine rotational speed have different changes in different stages. Since equivalent combustion is employed, the amount of engine air directly determines the amount of fuel injected, which directly determines the engine torque output. When the opening degree of the throttle valve is larger, the air inflow is higher, the fuel gas injection quantity is larger when the throttle valve is twisted, the torque output of the engine is larger, the gear shifting quality is slightly poor, and the power output of the engine is better. When the opening degree of the throttle valve is smaller, the air inflow is lower, the fuel injection quantity is smaller at the initial moment of torque, the torque output of the engine is smaller, the power output of the engine is weaker at the moment, and the gear shifting quality of the gearbox is better. Therefore, the working mode of the gearbox can be considered, and the throttle valve at the time of clearing the kink is subjected to compensation control based on the opening degree of the accelerator pedal, so that the economy in the E mode and the dynamic performance in the P mode can be improved.
Further, when the shift type is a downshift, the number of downshifts, that is, the difference between the current gear and the target gear, may be calculated from the current gear and the target gear. Further, the corresponding throttle compensation opening degree, that is, the second throttle compensation opening degree is determined by the number of downshifts and the accelerator pedal opening degree. The second throttle valve compensation opening degree is positively correlated with the number of downshifts and is positively correlated with the accelerator pedal opening degree, that is, the larger the number of downshifts is, the larger the second throttle valve compensation opening degree is, the stronger the user driving demand is, the larger the accelerator pedal opening degree is, and the larger the second throttle valve compensation opening degree is. Thus, the throttle valve compensation is controlled by the torque control end point in accordance with the second throttle valve compensation opening degree.
Table 3: data table of second throttle valve compensation opening corresponding to different downshift numbers and accelerator pedal opening
As shown in table 3, the data table records therein the second throttle valve compensation opening degrees corresponding to the different downshift numbers and the accelerator pedal opening degrees. It should be noted that, the second throttle compensation opening corresponding to the number of downshifts and the accelerator pedal opening shown in table 3 is only an example, and different values may be set in different scenes, which is not limited to the embodiment of the present invention.
Referring to fig. 5, fig. 5 is a schematic diagram of throttle compensation control during an AMT downshift according to an embodiment of the invention. As shown in fig. 5, the engine has three stages of torque control, speed regulation and torque returning during AMT downshift, and the throttle opening, the fuel injection amount, the engine torque output and the engine rotational speed have different changes in different stages. The throttle opening at the end of the torque clearing process determines the air inflow of the engine at the starting moment of speed regulation, so that the fuel gas injection quantity and the engine torque at the starting moment of speed regulation are influenced, and the rising slope of the engine torque and the speed regulation process time are further influenced. Therefore, the throttle opening at the time of clearing the kink is compensation-controlled based on the number of downshifts and the accelerator pedal opening. When the opening degree of the accelerator pedal is larger and the number of downshifts is larger, the speed regulation rotating speed required by the engine is larger, and at the moment, the opening degree is adjusted upwards on the basis data of the opening degree of the throttle valve, so that the air inflow is more sufficient, the fuel gas amount is more, the torque rising speed is further improved, the engine rotating speed rising speed is further improved, and the speed regulation time is optimized.
In addition, in order to enable the throttle control to adapt to different road conditions, the embodiment of the invention can also correct the throttle compensation opening based on the vehicle weight and the road gradient. Referring to fig. 6, fig. 6 is a flowchart of another method of the throttle control method according to the embodiment of the present invention. As shown in fig. 6, the throttle control method further includes the steps of:
and S40, acquiring the weight and the road gradient.
S50, determining a matched correction coefficient according to the vehicle weight and the road gradient, wherein the correction coefficient is positively correlated with the vehicle weight and the road gradient.
S60, correcting the throttle valve compensation opening according to the correction coefficient.
In the embodiment of the invention, the correction coefficients corresponding to different vehicle weights and road gradients can be calibrated in advance, and the corresponding relation is recorded into the corresponding mapping table. In the actual running of the vehicle, the current vehicle weight and the road gradient can be acquired, and then the correction coefficient corresponding to the vehicle weight and the road gradient is determined by inquiring the mapping table, and the throttle valve compensation opening is corrected by the correction coefficient, namely, the product of the correction coefficient and the throttle valve compensation opening is used as the corrected throttle valve compensation opening. Of course, the correction factor is positively correlated with the vehicle weight and positively correlated with the road gradient, i.e., the greater the vehicle weight, the greater the correction factor, the greater the road gradient, and the greater the correction factor.
Correspondingly, the step S30 of controlling the throttle valve according to the throttle valve compensation opening degree is specifically: and controlling the throttle valve according to the corrected throttle valve compensation opening. That is, the throttle valve is compensation-controlled by the corrected throttle valve compensation opening degree.
Through the description, the throttle valve control method provided by the invention can perform throttle valve compensation control based on the E/P mode of the gearbox and the opening degree of the accelerator pedal when the AMT is shifted up, and improves the gear shifting quality in the E mode and the dynamic property in the P mode; and when the AMT is in downshift, throttle valve compensation control is performed based on the downshift number and the accelerator pedal opening, so that the speed regulation performance of the engine under different downshift numbers is improved, and the gear shifting time is optimized.
Based on the throttle control method provided by the embodiment, the embodiment of the invention correspondingly provides a device for executing the throttle control method.
