As described in the background art of the present application, in the prior art, for the problem of detecting the full operating conditions of the engine, the technical solution of judging the pressure deviation value to determine the engine operating conditions is often adopted. In the solution of the prior art, the pressure deviation value is determined by the collected manifold pressure value and the preset pressure deviation value. After the pressure deviation value is determined, the current working condition of the engine is determined by judging the pressure deviation value and the pressure deviation threshold value. working status. Among them, the pressure deviation threshold is usually determined by the current speed of the engine and the amount of oil.

However, in actual use, in some operating conditions, the detection of the engine state may be inaccurate or delayed. The inventor's research found that when the opening deviation of the electronically controlled air release valve of the supercharger is large, the detection of the engine state will be inaccurate or delayed. Based on this, in order to achieve accurate and timely under all working conditions To detect the engine state, the present invention proposes an engine control method, as shown in FIG. 1 . Wherein, the shown method can be applied to an electronic control unit (Electronic Control Unit, ECU).

Referring to Figure 1, the following steps may be included:

S10. Obtain the pressure deviation value of the manifold and the opening degree deviation value of the electronically controlled air release valve.

Specifically, in this embodiment, the pressure deviation value of the manifold can be obtained by directly collecting the manifold pressure value and calculating it with the manifold pressure setting value. Exemplarily, the pressure value of the manifold can be obtained by, for example, including a pressure sensor, a pressure detection circuit, and other implementations that can realize pressure measurement. No specific limitation is made in the present invention.

Specifically, in this embodiment, the deviation value of the opening degree of the electronically controlled air release valve can be obtained by directly obtaining the opening degree value of the electronically controlled air release valve and calculating it with the set value of the opening degree of the electronically controlled air release valve, Exemplarily, the ECU can directly read the opening signal of the electronically controlled air release valve to determine the opening value of the electronically controlled air release valve, and the ECU can collect the engine speed signal and/or the oil quantity signal to determine the electronically controlled air release valve. The opening value of the electronically controlled air release valve can also be obtained through the ECU to obtain signals from other modules associated with the electronically controlled air release valve to determine the opening value of the electronically controlled air release valve. Experimental determination, for example: in a device that has a stable air source to provide air pressure, and adjusts the air pressure through PWM modulation through an electronically controlled pressure regulating valve to control the opening of the electronically controlled air release valve, the current duty cycle collected by the ECU can be used. The air pressure corresponding to the duty cycle under normal conditions is determined based on the duty cycle signal, thereby determining the opening value of the electronically controlled air release valve corresponding to the duty cycle signal under normal conditions as the opening degree setting value.

In the embodiment of the present invention, after the pressure deviation value of the manifold and the opening deviation value of the electronically controlled air release valve are obtained, the engine state can be determined according to the preset interval in which the pressure deviation value and the opening deviation value are located, and the specific engine state is determined. The steps may be performed according to step S20.

S20. Determine the engine state according to the preset interval in which the pressure deviation value and the opening deviation value are located.

Wherein, the preset interval of the pressure deviation value and the opening deviation value can be directly read by the ECU, or can be determined by experiments, for example, the test pressure deviation value and the opening deviation value are less than the working conditions under which the engine can work normally During operation, the interval corresponding to the opening deviation value at this time is taken as the preset interval of the opening deviation value, and the interval corresponding to the pressure deviation value is taken as the preset interval of the pressure deviation value.

Wherein, the engine state may be a normal working state or an abnormal working state. It can be understood that the normal working state and the abnormal working state are only an optional division method based on the engine operating state, and other divisions may also be made based on the engine operating conditions.

It can be understood that when the pressure deviation value and the opening deviation value are within the preset range, the engine is in a normal working state, and when the pressure deviation value and/or the opening deviation value are outside the preset range, the engine is in an abnormal working state. When the engine is in an abnormal state, specific control strategies such as outputting prompt information and adjusting torque can be specifically implemented for the engine. It can be understood that other operations, such as adjusting the oil amount, adjusting the intake air amount, etc., can also be performed to help reduce the abnormal state of the engine.

In the engine control method of the present application, the engine state is determined based on the preset interval in which the pressure deviation value of the manifold and the opening degree deviation value of the electronically controlled purge valve are located. Since the opening deviation of the electronically controlled bleed valve will affect the actual value of the manifold pressure, when detecting the engine state, in addition to considering the pressure deviation value, the opening deviation of the electronically controlled bleed valve is also taken as Influencing factors are taken into account and used together as the detection factors affecting the detection of the engine state, which can solve the phenomenon of inaccuracy or delay in the detection of the engine state in some working conditions when only the pressure deviation value is used, so as to achieve accurate detection under all working conditions. , Timely detection of engine status.

As an optional embodiment, determining the engine state according to the pressure deviation value and the preset interval in which the opening deviation value is located includes:

It is judged whether the opening degree deviation value is smaller than the opening degree deviation threshold value; when the opening degree deviation value is smaller than the opening degree deviation threshold value, the state of the engine is determined based on the preset interval in which the pressure deviation value is located.

Optionally, when the opening degree deviation value is greater than the opening degree deviation threshold value, a signal representing the forced torque limit is output.

The opening deviation threshold can be determined through experiments. For example, when the engine opening deviation is less than a certain value, the engine runs normally, and the corresponding opening deviation at this time is used as the opening deviation threshold.

It can be understood that when the opening deviation value is less than the opening deviation threshold value, it is confirmed that the opening deviation value is within the preset interval, and it can be considered that the electronically controlled air release valve is in a normal working state. The preset interval of the engine determines the state of the engine.

It can be understood that when the opening deviation value is greater than the opening deviation threshold value, it is confirmed that the opening deviation value is not within the preset interval, and it can be considered that the electronically controlled air release valve is in an abnormal working state, and the It is used to characterize the signal of forced torque limit, which is used to protect the engine.

As an optional embodiment, the determining the state of the engine based on the preset interval in which the pressure deviation value is located includes: judging whether the pressure deviation value is greater than a first pressure deviation threshold value.

Specifically, in this embodiment, determining the state of the engine based on the preset interval in which the pressure deviation value is located includes: judging whether the pressure deviation value is greater than a first pressure deviation threshold value.

Wherein, the first pressure deviation threshold can be determined through experiments, for example, to test the specific value of the pressure deviation value which will cause the engine to be abnormal and unable to maintain the power of the engine running. The pressure deviation value at this time is taken as the corresponding first pressure deviation threshold value.

It can be understood that, when the engine operates abnormally, the deviation between the engine manifold pressure value and the manifold pressure setting value will be greater than the first deviation threshold, and it can be determined based on this that the engine is in an abnormal working state.

As an optional embodiment, when the pressure deviation value is less than the first pressure deviation threshold value:

It is judged whether the pressure deviation value is greater than a second pressure deviation threshold value.

Wherein, the second pressure deviation threshold value can be determined through experiments, for example, to test the specific value of the pressure deviation value that will cause the engine to start abnormally, but can maintain the power of the engine running. The pressure deviation value at this time is taken as the corresponding second pressure deviation threshold value.

It can be understood that when the engine is working normally, the deviation between the engine manifold pressure value and the manifold pressure setting value will be smaller than the second deviation threshold, and when the engine is working abnormally, the engine manifold pressure value and the manifold pressure setting value will be less than the second deviation threshold. The deviation between the setpoints may be greater than the second deviation threshold, based on which the engine operating state may be determined.

As an optional embodiment, when the opening degree deviation value is greater than the opening degree deviation threshold value, a signal for characterizing the forced torque limit is output.

The opening deviation threshold can be determined through experiments, for example, to test which specific value of the opening deviation will cause the engine to be abnormal, the opening deviation at this time can be used as the corresponding opening deviation threshold.

Based on the above-mentioned optional embodiment, the pressure deviation value of the manifold and the opening degree deviation value of the air release valve are obtained, and the engine state is determined according to the preset interval in which the pressure deviation value and the opening degree deviation value are located. Wherein, as an exemplary embodiment, determining the engine state according to the preset interval in which the pressure deviation value and the opening deviation value are located may be:

When the opening deviation value is in the preset interval and the pressure deviation value is in the preset interval, it is confirmed that the working state of the engine is a normal state.

When the opening deviation value is in the preset range and the pressure deviation value is greater than the second pressure deviation threshold and smaller than the first pressure deviation threshold, it is confirmed that the engine operating state is abnormal, and a warning signal is output.

When the opening deviation value is in the preset range and the pressure deviation value is greater than the first pressure deviation threshold value, it is confirmed that the engine operating state is abnormal, and a signal representing the forced torque limit is output.

When the opening deviation value is not within the preset range, it is confirmed that the engine operating state is abnormal, and a signal representing the forced torque limit is output.

Through the above technical scheme of obtaining the pressure deviation value of the manifold and the opening degree deviation value of the air release valve, and determining the engine state according to the preset interval in which the pressure deviation value and the opening degree deviation value are located, the full working conditions of the engine can be more accurately determined. test.

However, in the actual implementation process of the above solution, under some working conditions, the detection of the engine state is still inaccurate. The inventors have found that when the supercharger air release valve is set to different opening degrees, There will be an inaccuracy in the detection of the engine state. Based on this, in order to weaken the influence of different opening degrees of the purge valve on the detection effect of the engine state and detect the engine state in time, based on the above control method, the embodiment of the present invention further proposes a more optimized control method.

As an optional embodiment, when the opening degree deviation value is smaller than the opening degree deviation threshold value:

The first pressure deviation threshold and the second pressure deviation threshold are adjusted based on an opening value.

Wherein, the opening degree value can be determined by directly reading the opening degree signal of the air release valve by the ECU, and the opening degree value can also be determined by collecting the engine speed signal and/or the fuel quantity signal by the ECU.

As an exemplary embodiment, when the opening value is zero, the first deviation threshold and the second deviation threshold are adjusted based on the opening value to be the first deviation threshold and the opening value when the opening value is zero The second deviation threshold at time zero.

When the opening degree value is not zero, an exemplary specific opening degree value whose opening degree value is not zero is arbitrarily selected to adjust the first deviation threshold value and the second deviation threshold value as the first deviation threshold value whose opening degree value is not zero. and a second deviation threshold whose opening value is not zero.

It can be understood that, when the opening value is zero, it can indicate that the electronically controlled air release valve is in stop working. When the opening is not zero, it can indicate that the electronically controlled air release valve is in a working state. The first deviation threshold when the opening value is zero is different from the deviation threshold when the opening value is not zero; the second deviation threshold when the opening value is zero and the second deviation threshold when the opening value is not zero are different. different.

As an exemplary embodiment, when the opening degree value is not zero, a plurality of exemplary opening degree value adjustment first deviation thresholds and second deviation threshold values with which the opening degree values are not zero are selected as the plurality of opening degree values A first deviation threshold and a second deviation threshold that are not zero.

Wherein, the plurality of first deviation thresholds whose opening degree values are not zero or the plurality of second deviation thresholds whose opening degree values are not zero may have a linear relationship or a non-linear relationship. For example, as the opening value increases, the first deviation threshold and/or the second deviation threshold corresponding to the opening value linearly increases; it may be that as the opening value increases, the first deviation threshold corresponding to the opening value increases And/or the second deviation threshold shows a trend of, for example, an S-curve (S-Curve), or as the opening value increases, the first deviation threshold and/or the second deviation threshold corresponding to the opening value is, for example, Logarithmic functions, etc., have a tendency to gradually decrease the slope of the function as the value of the function increases. It can be understood that the first deviation threshold value and the second deviation threshold value with the opening degree of zero and the first deviation threshold value and the second deviation threshold value of which the opening degree is not zero can be determined through mathematical models, and can be determined through specific experiments, or It can be determined in other achievable manners, and is not specifically limited in the present invention.

Through the above exemplary embodiment, the influence of different opening degrees of the air release valve on the detection effect of the engine state is reduced, the engine state is detected in time, and it is solved that when the air release valve of the supercharger is set to different opening degrees, There is a problem that the detection of the engine state is inaccurate.

As an exemplary embodiment, the present invention provides a specific engine control method, the engine control method includes:

Determine whether the opening value of the electronically controlled air release valve is zero.

When the opening value of the electronically controlled air release valve is zero, determine whether the pressure deviation value is less than the second pressure deviation threshold value of zero opening degree: when the pressure deviation value is less than the second pressure deviation threshold value of zero opening degree, confirm that the engine is working The status is normal.

When the pressure deviation value is not less than the second pressure deviation threshold with zero opening and the pressure deviation is not greater than the first pressure deviation threshold with zero opening, it is confirmed that the engine operating state is abnormal, and a warning signal is output.

When the pressure deviation value is greater than the first pressure deviation threshold value with zero opening degree, it is confirmed that the engine operating state is abnormal, and a signal representing the forced torque limit is output.

When the opening value of the electronically controlled air release valve is not zero, determine the size of the opening degree deviation value and the opening degree deviation threshold value, and the pressure deviation value and the second pressure deviation threshold value whose opening degree is not zero:

When the opening degree deviation value is not greater than the opening degree deviation threshold value and the pressure deviation value is not greater than the second pressure deviation threshold value where the opening degree is not zero: confirm that the engine working state is a normal state.

When the opening degree deviation value is not greater than the opening degree deviation threshold value and the pressure deviation value is greater than the second pressure deviation threshold value where the opening degree is not zero and is not greater than the first deviation threshold value where the pressure is not zero, it is confirmed that the engine operating state is abnormal, and the output Warning sign.
