In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented 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, system, article, or apparatus 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 apparatus.
According to one aspect of the embodiment of the application, an engine correction method for an engineering vehicle is provided. Alternatively, in the present embodiment, the above-described engineering vehicle engine correction method may be applied to a hardware environment constituted by the terminal 102 and the server 104 as shown in fig. 1. As shown in fig. 1, the server 104 is connected to the terminal 102 through a network, which may be used to provide services to the terminal or a client installed on the terminal, may set a database on the server or independent of the server, may be used to provide data storage services to the server 104, and may also be used to process cloud services, where the network includes, but is not limited to: the terminal 102 is not limited to a PC, a mobile phone, a tablet computer, etc., but is a wide area network, a metropolitan area network, or a local area network. The method for correcting the engine of the engineering vehicle in the embodiment of the present application may be executed by the server 104, may be executed by the terminal 102, or may be executed by both the server 104 and the terminal 102. The terminal 102 may execute the engine correction method of the engineering vehicle according to the embodiment of the present application by a client installed thereon.
Taking the example that the terminal 102 and/or the server 104 execute the engine correction method of the engineering vehicle in this embodiment, fig. 2 is a schematic flow chart of an alternative engine correction method of the engineering vehicle according to an embodiment of the application, and referring to fig. 2, the flow of the method may include the following steps:
s10, acquiring change information of the handle opening value based on the time sequence.
S20, determining the brake execution state of the engineering vehicle according to the change information of the handle opening value.
S30, correcting the rotation speed of the engine when the engineering vehicle executes braking.
Through the steps, after the handle opening value and the change information of the handle opening value at each moment of the engineering vehicle are obtained, whether the vehicle is in a braking state or not can be pre-judged in advance according to the change information, if the vehicle is braking, the engine speed can be corrected in advance, the engine speed is reduced, the condition that the engine speed is too high is avoided, the potential harm of the engine is eliminated, and the service life of the engine is prolonged.
For the technical solution in step S10, the handle opening value and the change information of the handle opening value are acquired based on the time sequence. For example, when the engine starts to work, the electronic control unit (Electronic Control Unit, ECU) starts to monitor the opening value of the handle in real time, and when the handle is operated, the handle sends a voltage signal to the ECU, and according to the detected different voltage values, the position and corresponding action of the handle are determined, and the opening value of the handle at each moment is obtained according to the position of the handle, wherein the forward and backward movement of the engineering vehicle can be realized by operating the handle.
For the technical scheme in step S20, the brake execution state of the engineering vehicle is determined according to the change information of the handle opening value. For example, when the handle is operated, whether the engineering vehicle is in a braking execution state can be judged according to the handle opening values of the handles at different moments, when the handle opening value at the previous moment is larger than the handle opening value at the next moment, the engineering vehicle is judged to have a braking intention, the ECU starts to calculate a correction parameter for correcting the engine speed, and the engine speed is corrected based on the correction parameter.
In the step S30, when the brake is performed on the working vehicle, the rotational speed of the engine is corrected. For example, when the vehicle is braked, the engine speed may be corrected by correcting the set engine speed, by correcting the engine speed at the time when the engine speed has been increased, by correcting the set engine speed first, and by correcting the engine speed again after the engine speed has been increased. The correction of the rotation speed of the engine can be based on the change rate of the handle, after the change rate of the handle is obtained, the correction parameters required for the correction of the rotation speed of the engine aiming at the current working condition are obtained through table lookup, and then the correction parameters are used for correcting the rotation speed of the engine, wherein the process of the correction is to reduce the rotation speed of the engine, and the change rate of the handle is positively correlated with the correction parameters.
The set rotational speed of the engine is corrected based on the change information of the handle opening value, and since the set rotational speed is reduced, the rotational speed of the engine is changed according to the corrected set rotational speed when the brake is performed by the working vehicle, and the increase rate of the rotational speed and the maximum value of the rotational speed are both reduced compared with those before correction, however, the change information of the handle opening value may be changed in the whole course, for example, the change rate of the hand-change opening value may be in a continuously changing state during the process of reducing the handle opening value, and therefore, the change curve of the actual rotational speed of the engine may be different from the set change curve, and a situation may occur in which the rotational speed of the engine is suddenly increased due to the excessively large change rate of the opening value. Therefore, as an alternative embodiment, after correcting the set rotation speed of the engine, checking whether the current rotation speed variation trend of the engine is approaching the corrected set rotation speed of the engine, if not, obtaining a corresponding handle opening variation rate based on a handle opening value corresponding to the current rotation speed of the engine, obtaining a correction parameter based on the current handle opening variation rate, and then correcting the current rotation speed of the engine again based on the correction parameter.
As an alternative embodiment, the engine speed may be corrected by setting a fixed value of the engine speed, when the ECU detects that the engine speed is greater than the fixed value of the set engine speed, the current handle opening rate is obtained, and the correction parameter is obtained based on the current handle opening rate, and then the current engine speed is corrected, however, after the correction is completed, if the speed of returning the driver operating handle increases, the engine speed may be affected again, so that the engine speed is greater than the set engine speed again, and therefore, after the correction is performed on the current engine speed based on the set engine speed, a new fixed value of the engine speed may be set based on the current engine speed, or the corrected engine speed may be corrected again based on the steps in this embodiment, by this way, the fixed value of the set engine speed and the current engine speed are corrected in a plurality of calibration manners, so that the probability of overshoot of the engine speed is further reduced, and the engine damage is avoided.
As an alternative embodiment, the engine speed may be corrected based on the trend of the handle opening value, under the normal working condition, when the handle is pushed back to the middle position only from the current position, the trend of the handle opening value is a decreasing trend, and the corresponding trend of the engine speed is also a decreasing trend, when the ECU detects that the trend of the current engine speed and the trend of the handle opening value do not conform to the expected trend, the ECU obtains the corresponding handle opening value based on the current handle opening value, obtains the correction parameter based on the handle opening value, corrects the engine speed based on the current correction parameter, however, when the trend of the handle opening value and the trend of the engine speed are both decreasing trends, the situation that the handle opening value is changed too much may occur, and the engine speed is increased to the extent that the engine is damaged, so that in this embodiment, the ECU needs to detect the trend of the handle opening value in real time, when the handle opening value is changed too much at two or several adjacent moments, the ECU obtains the handle opening value based on the current handle opening value, obtains the correction parameter based on the handle opening value, and then corrects the current engine speed, and also sends an alarm signal to the driver when the warning module is turned back to the warning module, and the warning module is turned down, and the warning module is turned back to the warning module is turned down, and the engine is turned down, and the danger is turned down, and the engine is turned down, the warning module is turned back to the engine is on.
As an exemplary embodiment, the correcting the rotation speed of the engine includes: determining an engine speed correction parameter based on the handle opening change information, wherein the correction parameter is used for reducing the engine speed; and correcting the engine speed based on the correction parameter.
In this embodiment, after the correction parameters are obtained, the ECU performs related control to correct the engine speed, and when the ECU controls the engine to complete the speed correction, the corrected engine speed is obtained, the correction effect is analyzed, and the process of calculating the correction parameters can be optimized based on the correction effect.
As an exemplary embodiment, the determining the engine speed correction parameter based on the handle opening degree variation information includes: determining a handle opening change rate based on the handle opening change information; and determining a correction parameter value based on the handle opening change rate, wherein the correction parameter is positively correlated with the handle opening change rate.
In this embodiment, when it is determined that the engineering vehicle performs braking, the handle opening change rate between the actual handle opening value corresponding to the current working condition and the preset handle opening value may be calculated, and the greater the handle opening change rate, the greater the influence on the rotational speed of the engine, and the greater the engine rotational speed is also increased.
As an exemplary embodiment, the determining the handle opening degree change rate based on the handle opening degree change information includes: acquiring an initial opening value when the opening value of the handle starts to be reduced and a first time parameter required when the opening value reaches a preset opening value; and determining the handle opening change rate based on the initial opening value, the preset opening value and the first time parameter.
In this embodiment, the preset handle opening value may be any positive number within less than 5%, or may be 0%, and when the preset handle opening value does not take 0%, the portion where the engine rotational speed increase rate exceeds the preset engine rotational speed increase rate is corrected according to the correction parameter obtained by the corresponding handle opening change rate, and the portion where the preset handle opening value is reduced to 0% may be regarded as having less influence on the rotational speed of the engine, and is not corrected.
It should be noted that the preset opening value of the handle may also be 6% and 7%, and may be adjusted according to different engine models, and specific numbers in this embodiment are only for explaining the present invention, and do not limit the protection scope of the present invention.
As an exemplary embodiment, the determining the brake execution state of the engineering vehicle according to the change information of the handle opening value includes: judging whether the opening value of the handle starts to be reduced or not; and when the opening value of the handle starts to decrease, determining that the engineering vehicle executes braking. The judging whether the handle opening value starts to be reduced comprises the following steps: acquiring handle opening values at least at two adjacent continuous moments; and determining that the handle opening value starts to be reduced when the handle opening value at the later moment in the continuous at least two adjacent moments is smaller than the handle opening value at the former moment.
In this embodiment, determining whether the handle opening value decreases may be to obtain two handle opening values at adjacent times, and then compare the two opening values, where when the handle opening value at the previous time is greater than the handle opening value at the next time, it may be determined that the engineering vehicle is in a braking executing state; judging whether the handle opening value is reduced or not can also be respectively obtaining handle opening values at two moments, and when the handle opening value at the current moment is larger than the handle opening value at the later moment and the duration exceeds a second time parameter, determining that the engineering vehicle is in a braking executing state; the method may further include sequentially taking handle opening values at a plurality of times based on a time sequence, and determining that the engineering vehicle is in a braking execution state if the plurality of handle opening values are sequentially reduced.
As an exemplary embodiment, the determining that the handle opening value starts to decrease includes: when the handle opening value at the later moment is not smaller than the handle opening value at the previous moment, determining that the engineering vehicle does not execute braking, and returning to the step of judging whether the handle opening value starts to be reduced.
In this embodiment, after determining that the handle opening value starts to decrease, the ECU still acquires the handle opening value at each moment in real time, when the handle opening value at the next moment is not smaller than the handle opening value at the previous moment, it may be determined that the driver has no braking intention, the engineering vehicle is not in a braking state, at this time, the engine speed is not corrected, the ECU determines whether the handle opening value decreases again, and the ECU acquires the handle opening value in real time, so that the probability of error correction of the engine speed may be reduced, so that correction of the engine speed is more accurate, and the engine is further protected.
