All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
As described above, the hybrid vehicle type market is gradually occupied with the PHEV type with long mileage (the pure electric endurance mileage is more than or equal to 50 km). The gasoline can volatilize due to octane after being stored in the oil tank for a long time, combustion components are reduced, and the ethanol gasoline can volatilize due to ethanol to generate layering; or colloid generated by oxidation can cause the long-time fuel not to be used or the fuel utilization rate to be greatly reduced, and the long-time fuel not to be used can cause deterioration, thus influencing the performance of the engine, such as the fuel gel blocking the fuel injector, the combustion component volatilization causing the engine to work powerless, and the engine can cause the engine to malfunction or cause the complaint of users when the engine is used.
In view of this, the engine control method provided in the embodiment of the present application obtains the fueling event time interval; determining an engine control strategy according to the refueling event time interval, wherein the engine control strategy is used for indicating a strategy for detecting the running condition of a vehicle to control the starting of an engine based on a vehicle running mode and the refueling event time interval; and starting the engine according to the engine control strategy. In this way, a preset engine control strategy is determined according to different running modes of the vehicle and the interval time of two refueling events, the running condition of the vehicle is detected according to the engine control strategy corresponding to the current vehicle, and the engine is controlled to start according to the detection result, so that the fuel is consumed by the vehicle without using the engine for a long time, the vehicle faults are reduced, and the use feeling of a user is improved.

An engine control method provided in the present application is described below by way of one embodiment. Referring to fig. 1, fig. 1 is a flowchart of an engine control method according to an embodiment of the present application, where the control method provided by the embodiment may be executed by an engine control system, and includes:
s101, acquiring a refueling event time interval.
The fueling event time interval can be determined by the fuel level sensor reading the amount of fuel in the fuel tank, and the fuel amount increase is determined as a fueling event, with the time interval between fueling events being the time of fuel storage. In an actual application scenario, the time interval may be obtained from a record of a fueling event by the cloud.
In one possible implementation manner, the step S101 further includes:
step 1011: and acquiring a data set stored in the cloud.
The data set includes an occurrence time of a vehicle fueling event. In an actual application scene, the engine control method can be realized by combining with the Internet of vehicles, and the Internet of vehicles system is divided into three parts: the system comprises a vehicle-mounted terminal, a cloud computing processing platform and a data analysis platform. The vehicle-mounted terminal collects real-time running data of the vehicle and collects, stores and transmits all working information and static and dynamic information of the vehicle. The vehicle-mounted terminal consists of a sensor, a data acquisition unit and a wireless transmission module, and the real-time running conditions of the vehicle comprise the operation behaviors of a driver, the working parameter data of a power system, the occurrence time of a refueling event and the like; and the application wireless sending module sends the acquired data to the cloud computing processing platform, namely, the acquired data is integrated into a data set and stored in the cloud. In some possible implementations, vehicle information data acquired by cloud computing processing may be "filter cleaned" of the data.
The occurrence time of the vehicle refueling event in the data set can be determined together through a data collector and a sensor of the vehicle-mounted terminal, for example, the vehicle sensor can be used for identifying the oil storage condition in the vehicle oil tank, the data collector is used for identifying the fuel oil level signal, and the current vehicle refueling event is identified in response to the sensor or the data collector acquiring the increase of the fuel oil quantity in the vehicle oil tank.
Step 1012: and performing program operation processing on the data set to obtain a refueling event time interval.
And calling a program operation module in the cloud computing processing platform to perform program operation processing on the data set. For example, the time of occurrence of the last fueling event in the dataset may be obtained along with the current date, and the fueling event time interval may be calculated.
In some possible implementation manners, the data analysis platform in the internet of vehicles system can be called to carry out the form reporting processing on the data, so that a vehicle user or a manager can check the data, and when the vehicle passenger calls the vehicle data after the form reporting processing is completed, the time interval of the vehicle refueling event can be directly known.
S102, determining an engine control strategy according to the refueling event time interval.
The vehicle operation mode may include an EV (electric only mode), an HEV (hybrid mode), and a wading mode, among others.
The engine control strategy is a strategy for indicating that the vehicle running condition is detected to control the engine to start based on the vehicle running mode and the refueling event time interval, for example, in an actual application scenario, a normal value defining threshold (i.e. a first time threshold) of the refueling event time interval may be set to 120 days, and the system may determine the engine control strategy corresponding to the current vehicle according to the current refueling event time interval. Determining that the engine control strategy is a conventional control strategy when a fueling event time interval of the vehicle is not greater than a first time threshold; and when the refueling event time interval is larger than a first time threshold, determining that the engine control strategy is a deterioration prevention control strategy. The anti-deformation control strategies comprise four control strategies, and the four control strategies correspond to different refueling time intervals and vehicle running modes respectively.
S103, starting the engine according to the engine control strategy.
And controlling the engine to start according to one of the five control strategies according to the control strategy corresponding to the vehicle running mode and the refueling event interval time which are acquired in the steps.
In a first case, in response to determining that the engine control strategy is a first control strategy.
In the actual application process, namely, the system acquires that the vehicle running mode is an HEV hybrid power mode, the interval time of the refueling event accords with a first preset interval, and the engine control strategy is determined to be a first control strategy. The HEV mode adopts pure electric energy under the general condition, and realizes the hybrid use of oil and electricity under the condition of lower electric quantity. Under the condition that the refueling event interval time accords with a first preset interval, the whole vehicle running mode only adopts an HEV hybrid power mode and does not run other modes such as an EV pure electric mode, and in an actual application scene, the system controls the vehicle to automatically switch to the HEV mode even if a vehicle occupant sets the vehicle to be in the other modes such as the EV mode.
The first control strategy is a control strategy for determining whether to start the engine or not based on the magnitude relation between the battery electric quantity and a first electric quantity threshold value. I.e., the first control strategy is the engine control strategy invoked when the first control strategy corresponds to the hybrid mode and the fueling event interval time corresponds to the first preset interval. The first control strategy includes an engine control strategy when the current power battery charge is not greater than a first charge threshold and an engine control strategy when the current power battery charge is greater than the first charge threshold and not greater than a second charge threshold.
In the subsequent method steps, firstly, the electric quantity of the power battery is obtained, and then, the engine is started according to the engine control strategy, wherein the two conditions are the condition A1 and the condition A2:
a1: an engine is started in response to the power battery charge being not greater than a first charge threshold.
For example, the first preset interval is set to be that the interval time of the refueling event is more than 120 days and not more than 150 days, when the first electric quantity threshold is 30%, the engine is started when the electric quantity of the power battery is less than or equal to 30%.
A2: acquiring the running speed and the required power of the vehicle in response to the power battery electric quantity being greater than a first electric quantity threshold and not greater than a second electric quantity threshold; an engine is started in response to the vehicle operating speed being less than a first speed threshold and the demanded power being greater than a first power threshold.
When the electric quantity of the power battery of the vehicle is detected to be more than 30% and less than 80%, 80% of the electric quantity is a preset second electric quantity threshold value, the system obtains the running speed and the required power of the vehicle, the obtained value is compared with the preset threshold value, for example, the first speed threshold value is set to be 40km/h, the first power threshold value is set to be 20kw, and when the running speed of the whole vehicle is less than 40km/h and the required power is greater than 20kw, the engine is started.
In a second case, in response to the vehicle operating mode being a hybrid mode, the fueling event interval time conforms to a second preset interval, and the engine control strategy is determined to be a second control strategy.
In the actual application process, under the condition that the interval time of the refueling event accords with a second preset interval, the whole vehicle running mode only adopts an HEV hybrid power mode and does not run other modes such as an EV pure electric mode, and in the actual application scene, even if a vehicle occupant sets the vehicle to be in other modes such as the EV mode, the system controls the vehicle to automatically switch to the HEV mode.
The third control strategy is a control strategy for determining whether to start the engine or not based on the magnitude relation between the battery power and a third power threshold. I.e., the second control strategy is the engine control strategy invoked when the corresponding hybrid mode and the fueling event interval time meets the second preset interval. The second control strategy includes an engine control strategy when the current power battery charge is not greater than a third charge threshold and an engine control strategy when the current power battery charge is greater than the third charge threshold and not greater than a fourth charge threshold.
In the subsequent method steps, firstly, the electric quantity of the power battery is obtained, and then, the engine is started according to the engine control strategy, wherein the two conditions are the condition B1 and the condition B2:
b1: and starting the engine in response to the power battery charge being not greater than a third charge threshold.
For example, the second preset interval is set to be that the interval time of the refueling event is greater than 150 days and not greater than 180 days, when the third electric quantity threshold is 50%, the engine is started when the electric quantity of the power battery is less than or equal to 50%.
B2: acquiring the running speed and the required power of the vehicle in response to the power battery electric quantity being greater than a third electric quantity threshold and not greater than a fourth electric quantity threshold; an engine is started in response to the vehicle operating speed being less than a second speed threshold and the demanded power being greater than a second power threshold.
When the electric quantity of the power battery of the vehicle is detected to be more than 50% and less than 80%, 80% of the electric quantity is a preset fourth electric quantity threshold value, the system obtains the running speed and the required power of the vehicle, the obtained value is compared with the preset threshold value, for example, a second speed threshold value is set to be 40km/h, the second power threshold value is set to be 10kw, and when the running speed of the whole vehicle is less than 40km/h and the required power is greater than 10kw, the engine is started.
And in a third case, determining that the engine control strategy is a third control strategy in response to the vehicle running mode being a wading mode, wherein the fueling event interval time accords with a third preset interval.
In the practical application process, the engine in the HEV can be directly driven, connected in series or connected in parallel, wherein the engine can charge the vehicle battery and drive the wheels, or can not drive the wheels to charge the vehicle battery only. Under the condition that the interval time of the refueling event accords with a third preset interval, the whole vehicle running mode only adopts a wading mode, after the whole vehicle is electrified, the engine is controlled to run to directly drive wheels, other modes such as an EV pure electric mode or an HEV hybrid power mode are not operated, and in an actual application scene, even if a vehicle passenger sets the vehicle to be in the EV mode or the HEV hybrid power mode and other modes, the system also controls the vehicle to be automatically switched to the wading mode.
Wherein the third control strategy is for directly instructing to start the engine. For example, the third preset interval may be set to be greater than 180 days and not greater than 240 days during the refueling event, and the engine is started to run regardless of the remaining power of the power battery in the present case.
And in a fourth case, determining that the engine control strategy is a fourth control strategy in response to the vehicle operating mode being a wading mode, wherein the fueling event interval time conforms to a fourth preset interval.
The fourth control strategy is used for indicating to start the engine and generating prompt information before each start. For example, the fourth preset interval is set to be that the refueling event time interval is greater than 240 days, the engine is started to run no matter how much power battery remains in the current situation, and a reminding display instruction is generated before each start for reminding at the vehicle instrument before each start.
In a fifth scenario, the engine control strategy is determined to be a conventional control strategy in response to the fueling event time interval not being greater than a first time threshold.
In an actual application scenario, when the interval between the fueling events is not greater than the first time threshold, and the vehicle is in any vehicle running mode, the engine control strategy is determined to be a conventional control strategy. The Vehicle running mode may be a Vehicle running mode related to Vehicle Electric quantity, such as EV (Electric Vehicle), HEV (Hybrid Electric Vehicle, hybrid power), PHEV (plug in hybrid Electric Vehicle, plug-in hybrid power), or a personalized driving mode, such as an economy mode, a sport mode, an adaptive driving mode, an off-road mode, a normal mode, etc., and the Vehicle running mode in the conventional control strategy may be selected autonomously by a Vehicle occupant, or may be a recommended mode automatically generated by a Vehicle end according to a Vehicle running environment and running data, and in this case, the type and the selection mode of the Vehicle running mode may be adaptively adjusted according to actual requirements, without limitation.
A fifth case is that no greater than a normal value defines a threshold (first time threshold), wherein the conventional control strategy is a control strategy that determines whether to start the engine based on a magnitude relationship of the battery power to a fifth power threshold. I.e., the conventional control strategy is an engine control strategy that corresponds to an electric-only mode or a hybrid mode, and the fueling event time interval is not greater than a first time threshold. The conventional control strategy includes an engine control strategy when the current power battery charge is not greater than a fifth charge threshold and an engine control strategy when the current power battery charge is greater than the fifth charge threshold and not greater than a sixth charge threshold.
In the subsequent method steps, firstly, the electric quantity of the power battery is obtained, and then, the engine is started according to the engine control strategy, wherein the two conditions are the condition C1 and the condition C2:
case C1: and starting the engine in response to the power battery charge being not greater than a fifth charge threshold.
For example, when the fifth electric quantity threshold is set to 20%, the engine is started when the electric quantity of the power battery is 20% or less. In the practical application process, the engine can be applied to maintaining the electric quantity of the vehicle or charging the battery of the vehicle after the engine is started, and the application of the engine after the engine is started is not limited.
Case C2: acquiring the running speed and the required power of the vehicle in response to the power battery electric quantity being greater than a fifth electric quantity threshold and not greater than a sixth electric quantity threshold; an engine is started in response to the vehicle operating speed being less than a third speed threshold and the demanded power being greater than a third power threshold.
When the electric quantity of the power battery of the vehicle is detected to be more than 20% and less than 80%, 80% of the electric quantity is a preset sixth electric quantity threshold value, the system obtains the running speed and the required power of the vehicle, the obtained value is compared with the preset threshold value, for example, a third speed threshold value is set to be 50km/h, a third power threshold value is set to be 30kw, and when the running speed of the whole vehicle is less than 50km/h and the required power is more than 30kw, the engine is started.
The five control strategies in S102-S103 are integrated, wherein the values of the electric quantity threshold, the required power threshold, the vehicle speed threshold and the fueling event interval time threshold can be set according to actual requirements, the control strategy is not limited to the values exemplified above, and the value range can be adaptively modified.

And determining a preset engine control strategy according to different running modes of the vehicle and the interval time of two refueling events, detecting the running condition of the vehicle according to the engine control strategy corresponding to the current vehicle, and controlling the engine to start according to the detection result. Therefore, according to the corresponding engine control strategy determined based on the time interval of the refueling event of the vehicle, the vehicle which does not use the engine for a long time consumes fuel, reduces the vehicle faults and improves the use feeling of the user.
