Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the numerical values so used are interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, apparatus, article, or device that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or device.

Referring to the accompanying fig. 1, which is a schematic diagram illustrating an implementation environment provided by an embodiment of the present invention, as shown in fig. 1, the implementation environment may include at least: the motor, BSG motor, DC-to-AC converter and accumulator.

Referring to fig. 2 of the specification, fig. 2 is a schematic flow chart of a method for intervening engine output torque by using BSG according to an embodiment of the present invention, and as shown in fig. 2, the present invention provides a method for intervening engine output torque by using BSG, where an execution subject of the method may be an Electronic Control Unit (ECU) of an automobile, and an engine of the automobile is in a running state, and the method includes:

s102, obtaining current operation parameters and threshold torque of the automobile, wherein the current operation parameters at least comprise: crank angle, engine speed, engine output torque and battery charge.

Specifically, the current operating parameter may reflect an operating state of the vehicle, and the current operating parameter may include: the number of cylinders of the automobile is not specifically limited in the embodiment of the specification, and the crank angle, the engine speed, the engine output torque, the charge capacity of the storage battery and the like can be set according to actual needs. The output torque obtained by the ECU can reflect the working condition of the corresponding cylinder. The four-stroke engine is exemplified, namely four strokes of air intake, compression, power application and air exhaust, wherein the power application stroke outputs torque outwards; in a three-cylinder engine (or a four-cylinder/six-cylinder engine), each cylinder completes the processes of one-time air intake, compression, power application and exhaust in a period of two revolutions of a crankshaft; the working interval is 240 degrees (180 degrees for a four-cylinder machine and 120 degrees for a six-cylinder machine), the large torque corresponds to large cylinder pressure, the larger the cylinder pressure is, the larger the working interval is, and the more unstable the engine runs. The charge of the storage battery can reflect the maximum output torque of the BSG motor, and when the charge of the storage battery is too low, the output torque of the BSG motor can not meet the expected requirement.

Specifically, the threshold torque may be determined by a signal transmitted by the driver by lightly stepping on the accelerator or a current road condition, which may be a speed limit or a number of obstacles.

S104, judging whether the output torque of the engine is larger than the threshold torque or not;

specifically, the ECU may determine whether the engine output torque is greater than the threshold torque. When the engine output torque is larger than the threshold torque (the required torque), the engine output torque is larger, which easily causes the unstable operation of the engine.

And S106, if the output torque of the engine is larger than the threshold torque, judging whether the current operation parameters meet preset requirements.

Specifically, when the engine output torque is greater than the threshold torque, the ECU may determine whether the current operating parameter meets a preset requirement.

The preset requirement may be that whether the engine speed is within a preset speed threshold range is judged, if yes, whether the charge capacity of the storage battery is within a preset capacity threshold range is judged, and if yes, it is determined that the current operation parameter meets the preset requirement.

In some possible embodiments, the current operating parameters further include: an electrical load;

Specifically, the preset rotation speed threshold range, the preset electric quantity threshold range and the preset load threshold are not specifically limited in the embodiments of the present specification, and may be set according to actual needs, for example, the preset rotation speed threshold range may be between 700 rpm and 1200 rpm; the preset electric quantity threshold value range can be 30-80%.

Specifically, the preset load threshold may be determined according to the current charge of the storage battery, and the electric quantity corresponding to the electric load should be smaller than the charge of the storage battery.

And S108, if the preset requirement is met, determining target working parameters corresponding to the BSG at each crank angle according to the crank angle, the engine rotating speed, the engine output torque and the storage battery charge amount.

Specifically, when the current operating parameter meets the preset requirement, the ECU may determine the target operating parameter corresponding to the BSG at each crank angle according to the crank angle, the engine speed, the engine output torque, and the battery charge amount.

In some possible embodiments, the target operating parameter comprises: target power-assisted parameters and target power generation parameters;

Specifically, the rotating speed of the engine determines the required frequency of the BSG action, the output torque of the engine determines the required size of the BSG compensation, and the charge capacity of the storage battery determines the assistance or power generation capacity range of the BSG; the ECU can determine target operating parameters corresponding to the BSG at each crank angle according to the engine speed, the output torque and the battery charge.

And S110, calculating a control parameter according to the target working parameter, and sending the control parameter to the BSG, so that the BSG works according to the control parameter to intervene in engine torque output.

Specifically, for example, the BSG motor may implement power assistance or power generation on a curve corresponding to each cylinder pressure value, start power generation when the cylinder pressure value gradually increases and the threshold torque is equal to the output torque corresponding to each cylinder pressure value, and start power assistance when the cylinder pressure value gradually decreases and the threshold torque is equal to the output torque corresponding to each cylinder pressure value. Each individual cylinder pressure value may reflect an output torque of the engine.

The BSG motor can assist in ignition intervals, generate power near a torque peak value and suppress peaks and valleys, namely under the condition that the average value of the torque of a crankshaft of the engine is not changed, the maximum value of the instantaneous torque is reduced, the minimum value of the instantaneous torque is improved, the torque fluctuation is in a small range, and the capability of the engine for running stably and stably is improved; the running condition of the engine can be adjusted in a larger rotating speed and load range, and the optimal value of oil consumption and stability is selected.

Specifically, when the ECU determines that the difference between the current power generation parameter or the current boost parameter of the BSG and the target power generation parameter or the target boost parameter is greater than a preset threshold (the difference indicates that the difference is not matched), the ECU may perform PID correction on the target working parameter, so that the target working parameter is matched with the current working parameter.
