The control method of the electric control engine provided by the embodiment of the disclosure can be applied to the scene shown in fig. 1.
In the application scenario shown in fig. 1, an electronically controlled engine is provided on the vehicle 10 to power the vehicle 10.

The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present disclosure will be described below with reference to the accompanying drawings.
In one aspect, the embodiment of the disclosure provides a control method of an electronically controlled engine suitable for the above scenario.

In this step, the electronic control unit may receive a vehicle dynamic braking signal, and upon receiving the vehicle braking signal, acquire an ambient temperature and a water temperature of the electronically controlled engine.
The vehicle dynamic braking signal refers to a signal for indicating that the vehicle enters a dynamic braking mode. For example, when the driver performs a braking operation during the running of the vehicle, a corresponding vehicle dynamic braking signal is generated, and the vehicle enters a dynamic braking mode.
The environmental temperature refers to an environmental temperature corresponding to the electronically controlled engine, such as a temperature of the engine or a temperature of a space where the engine is located.
S202: and determining the target rotating speed corresponding to the electric control engine according to the ambient temperature, the water temperature and a preset mapping table.
Wherein, the mapping table records the mapping relation among all environment temperatures, all water temperatures and all rotating speeds.
In this step, according to the obtained ambient temperature and water temperature, the mapping table is queried to obtain a rotation speed corresponding to the ambient temperature and the water temperature, and the rotation speed is determined as a target rotation speed.
In the prior art, when the vehicle is in a dynamic braking mode, the rotation speed of the electronically controlled engine is a constant rotation speed. That is, if the vehicle is in the dynamic braking mode, the electronically controlled engine is rotated at a constant rotational speed.
However, in the embodiment of the present disclosure, the target rotation speed of the electronically controlled engine is selected according to the ambient temperature and the water temperature, and cooling and oil consumption are both considered, so that the energy is saved, the reliability of cooling is satisfied, and the technical effect of prolonging the service life of the vehicle is further achieved.

Now, taking a mining vehicle (hereinafter referred to as a mine car) as an example, the scheme and effect of the embodiment of the disclosure are explained in detail by combining the prior art as follows:
mine cars generally operate on relatively complex working conditions such as large downhill slopes, large uphill slopes, level roads and the like. Taking the statistical data of the inner Mongolia Shenhua Daigui coal mine as an example, the mine car runs in a dynamic braking mode in about 25% of the time, and the electric control engine only needs to provide power for the fan to cool in the dynamic braking mode.
In the prior art, the control method of the electronic control engine is to control the electronic control engine to operate at a constant rotating speed in a dynamic braking mode. However, if the set constant rotation speed ratio is high, the fuel consumption of the electronically controlled engine is also high, and if the set constant rotation speed ratio is low, the electronically controlled engine may not meet the cooling requirement of the fan.
In the embodiment of the disclosure, if the mine car is in the dynamic braking mode, the ambient temperature and the water temperature are respectively obtained, so that the rotating speed of the electronic control engine is determined based on the ambient temperature and the water temperature, and the electronic control engine is controlled to operate at the rotating speed.

In this step, if the driver performs an operation of stepping on the accelerator pedal, the first rotational speed may be determined based on the opening degree of the accelerator pedal, and the electronic control unit receives the rotational speed request, extracts the first rotational speed carried in the rotational speed request, and determines the magnitude of the first rotational speed and the target rotational speed.

And if the first rotating speed is lower than the target rotating speed, controlling the electrically controlled engine to operate at the first rotating speed so as to achieve the technical effect of saving energy.
S306: and controlling the electrically controlled engine to operate at the target rotating speed.
In this step, if the first rotation speed is greater than the target rotation speed, the electronically controlled engine is still controlled to operate at the target rotation speed because the target rotation speed is sufficient to meet the cooling requirement, thereby achieving the technical effect of saving energy.
Referring to fig. 4, fig. 4 is a schematic flow chart of a control method of an electronically controlled engine according to another embodiment of the present disclosure.

As shown in fig. 5, the method includes:
s51: and acquiring historical data corresponding to the electric control engine, wherein the historical data at least comprises each environment temperature, each water temperature, each oil consumption parameter, each cooling parameter and each rotating speed.
In this step, history data corresponding to the electronically controlled engine is acquired.
In some embodiments, historical data may be obtained over the last half year of an electronically controlled engine, wherein the time range corresponding to the historical data may be set based on demand, which is exemplary only and should not be construed as limiting the scope of the disclosed embodiments.
The historical data comprises relevant information of the electronic control engine in the running process or information relevant to the electronic control engine in the running process of the vehicle.
In the embodiment of the present disclosure, the historical data at least includes each ambient temperature, each water temperature, each oil consumption parameter, each cooling parameter, and each rotational speed.
For example: the environment temperatures comprise a1-an, the water temperatures comprise b1-bn, the oil consumption parameters c1-cn, the cooling parameters d1-dn and the rotating speeds comprise e1-en. The units of the ambient temperature and the water temperature can be both in centigrade, the unit of the oil consumption parameter can be in liters per kilometer, the cooling parameters can comprise a temperature parameter before cooling (the unit can be in centigrade), a temperature parameter after cooling (the unit can be in centigrade) and cooling efficiency (the unit can be in centigrade per minute), and the unit of the rotating speed can be in kilometers per hour.
S52: and determining the rotating speed with the highest matching degree with each environment temperature and each water temperature according to each oil consumption parameter and each cooling parameter.
The highest matching degree means that when the ambient temperature, the water temperature and the rotating speed are combined, the oil consumption parameter is the minimum, the cooling parameter is the maximum, and the cooling parameter means the cooling efficiency, namely the cooling parameter when the cooling effect is the best.
For example: when the ambient temperature is a, the water temperature is b, and the rotating speed is c, the oil consumption parameter is minimum, and the cooling parameter is maximum, and then the rotating speed c is determined as the rotating speed with the highest matching degree of the ambient temperature a and the water temperature b.
S53: and constructing a mapping relation between each rotating speed and each environment temperature and each water temperature corresponding to each rotating speed to generate a mapping table.
That is to say, when a certain environmental temperature and water temperature are determined, the rotating speed meeting the conditions that the oil consumption parameter is minimum and the cooling parameter is maximum under the condition of the environmental temperature and the water temperature can be obtained by inquiring the mapping table, and the technical effects of saving oil consumption and improving cooling efficiency can be realized by controlling the electric control engine to operate at the speed.
In some embodiments, the mapping table may be updated according to a preset time interval.
For example: after the vehicle runs for a certain time, performance parameters and the like may be changed, so a time interval may be set based on the requirement, so as to update the mapping table according to the time interval, thereby ensuring the technical effects of validity and reliability of the maximum rotating speed threshold value and the minimum rotating speed threshold value.
