Detailed Description
The following description of the embodiments of the present application 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 application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Example 1
Fig. 1 is a flowchart of a method for correcting the number of pre-injection times of an engine according to an embodiment of the present application.
As shown in fig. 1, the method for correcting the number of pre-injections provided in the present embodiment is applied to an electronic device of the engine, which may be understood as a device having a control function for the engine and having a data computing capability and an information processing capability, such as an ECU or an MCU, and the like, and includes the steps of:
s1, judging whether the engine is in a specific acceleration working condition or not.
Specifically, the method comprises the steps of judging according to an actual opening value and an opening change rate of an accelerator pedal received by an engine to determine whether the engine is in a specific acceleration working condition. The narrow interpretation of the accelerator pedal may be a control device of a vehicle in which the engine is provided in practice, and the broad interpretation of the accelerator pedal may be a pedal, a handle, or an automatic control device that directly or indirectly controls the engine. The actual opening value is an angle or an amplitude of change of the accelerator pedal when the user operates the accelerator pedal at the time of performing an acceleration operation. The opening rate is the rate of change of the angle or amplitude of the accelerator pedal per unit time. The embodiment specifically judges whether the engine is in a specific acceleration working condition or not through the following steps:
firstly, judging whether an actual opening value APP_r of the accelerator pedal accords with a preset opening condition, and stopping judging if the actual opening value APP_r does not accord with the preset opening condition, namely, the engine is certainly not under a specific acceleration working condition at the moment; and if the actual opening meets the preset opening condition, executing subsequent judgment. Specifically, the actual opening value app_r is compared with a preset opening threshold value a, if the actual opening value is smaller than the preset opening threshold value, the judgment is stopped, and if the actual opening value is larger than or equal to the preset opening threshold value, the subsequent steps are executed.
And then, judging the opening degree change rate R under the condition that the actual opening degree value accords with the preset opening degree condition, and judging that the engine is in a specific acceleration working condition if the opening degree change rate accords with the preset change rate condition. Specifically, the actual opening value is divided by a time period Δt that has elapsed from the initial state to reach the actual opening value, thereby obtaining the opening change rate; and then comparing the obtained opening change rate with a preset change rate threshold b, stopping the comparison if the opening change rate is smaller than the preset change rate threshold, and determining that the engine is in a specific acceleration state if the opening change rate is larger than or equal to the preset change rate threshold.
The actual opening value and the actual opening duration in the application are obtained through the bus of the engine, wherein the preset opening threshold value a and the preset change rate threshold value b can be obtained through bench test or can be obtained through calculation by other methods.
S2, searching the prejudgement correction times based on the current running state.
When the engine is determined to be in a specific acceleration working condition, searching is carried out from a preset prejudgement correction MAP table based on the current running state of the engine, such as the rotating speed, the torque or the output power, so that the corresponding prejudgement correction times are found. The following table is a MAP table:
| current number of pre-spray | Number of preliminary ejection corrections | Number of post-correction injections |
| 0 | 2 | 2 |
| 0 | 1 | 1 |
| 1 | 1 | 2 |
And S3, correcting the current pre-spraying times according to the pre-spraying correction times.
After the prejudgment correction times are obtained, the current preinjection times under the current working condition are corrected to obtain corrected injection times, wherein the current working condition can be the specific acceleration working condition or the current working state of the engine described by a plurality of other parameters.
As can be seen from the above technical solution, the present embodiment provides a method for correcting the number of pre-spraying times, where the method is applied to an electronic device of an engine, specifically, the method determines according to an actual opening value and an opening change rate of an accelerator pedal received by the engine, so as to determine whether the engine is in a specific acceleration condition; when the engine is in a specific acceleration working condition, searching from a preset pre-injection correction MAP based on the current running state of the engine to obtain the number of pre-injection correction times; and correcting the current pre-spraying times corresponding to the specific acceleration working condition according to the pre-spraying correction times. The method has the advantages that the corrected prejudgment is perfectly suitable for the acceleration process at the moment by adjusting the prejudgment times in the acceleration process, so that the noise mutation of the engine is avoided.

Example two
Fig. 2 is a block diagram of an apparatus for correcting the number of pre-injection times of an engine according to an embodiment of the present application.
As shown in fig. 2, the pre-spray number correction device provided in this embodiment is applied to an electronic device of the engine, and may also be understood as the electronic device itself. The electronic device may be understood as a device having a control function on the engine and having data computing capability and information processing capability, such as an ECU or an MCU, etc., and the pre-injection number correction device includes a condition judgment module 10, a correction value search module 20, and a correction execution module 30.
The working condition judging module is used for judging whether the engine is in a specific acceleration working condition or not.
Specifically, the method comprises the steps of judging according to an actual opening value and an opening change rate of an accelerator pedal received by an engine to determine whether the engine is in a specific acceleration working condition. The narrow interpretation of the accelerator pedal may be a control device of a vehicle in which the engine is provided in practice, and the broad interpretation of the accelerator pedal may be a pedal, a handle, or an automatic control device that directly or indirectly controls the engine. The actual opening value is an angle or an amplitude of change of the accelerator pedal when the user operates the accelerator pedal at the time of performing an acceleration operation. The opening rate is the rate of change of the angle or amplitude of the accelerator pedal per unit time. The working condition judging module includes a first judging unit 11 and a second judging unit 12, as shown in fig. 3.
The first judging unit is used for judging whether the actual opening value APP_r of the accelerator pedal accords with a preset opening condition, and stopping judging if the actual opening value APP_r does not accord with the preset opening condition, namely the engine is certainly not under a specific acceleration working condition at the moment; and if the actual opening meets the preset opening condition, executing subsequent judgment. Specifically, the actual opening value app_r is compared with the preset opening threshold value a, if the actual opening value is smaller than the preset opening threshold value, the judgment is stopped, and if the actual opening value is greater than or equal to the preset opening threshold value, the second judgment unit starts to execute.
The second judging unit is used for judging the opening degree change rate R when the first judging unit judges that the actual opening degree value accords with a preset opening degree condition, and judging that the engine is in a specific acceleration working condition if the opening degree change rate accords with the preset change rate condition. Specifically, the actual opening value is divided by a time period Δt that has elapsed from the initial state to reach the actual opening value, thereby obtaining the opening change rate; and then comparing the obtained opening change rate with a preset change rate threshold b, stopping the comparison if the opening change rate is smaller than the preset change rate threshold, and determining that the engine is in a specific acceleration state if the opening change rate is larger than or equal to the preset change rate threshold.
The actual opening value and the actual opening duration in the application are obtained through the bus of the engine, wherein the preset opening threshold value a and the preset change rate threshold value b can be obtained through bench test or can be obtained through calculation by other methods.
The correction execution module is used for searching the prejudgement correction times based on the current running state.
When the engine is determined to be in a specific acceleration working condition, searching is carried out from a preset prejudgement correction MAP table based on the current running state of the engine, such as the rotating speed, the torque or the output power, so that the corresponding prejudgement correction times are found. The following table is a MAP table:
| current number of pre-spray | Number of preliminary ejection corrections | Number of post-correction injections |
| 0 | 2 | 2 |
| 0 | 1 | 1 |
| 1 | 1 | 2 |
And S3, correcting the current pre-spraying times according to the pre-spraying correction times.
After the prejudgment correction times are obtained, the current preinjection times under the current working condition are corrected to obtain corrected injection times, wherein the current working condition can be the specific acceleration working condition or the current working state of the engine described by a plurality of other parameters.
As can be seen from the above technical solution, the present embodiment provides a device for correcting the number of pre-spraying times, which is applied to an electronic device of an engine, specifically, the device determines according to an actual opening value and an opening change rate of an accelerator pedal received by the engine, so as to determine whether the engine is in a specific acceleration condition; when the engine is in a specific acceleration working condition, searching from a preset pre-injection correction MAP based on the current running state of the engine to obtain the number of pre-injection correction times; and correcting the current pre-spraying times corresponding to the specific acceleration working condition according to the pre-spraying correction times. The method has the advantages that the corrected prejudgment is perfectly suitable for the acceleration process at the moment by adjusting the prejudgment times in the acceleration process, so that the noise mutation of the engine is avoided.
The units involved in the embodiments of the present disclosure may be implemented by means of software, or may be implemented by means of hardware. The name of the unit does not in any way constitute a limitation of the unit itself, for example the first acquisition unit may also be described as "unit acquiring at least two internet protocol addresses".
