Fig. 2 is a schematic flow chart of an engine starting method according to an embodiment of the present application, where:
in step 201: in response to a start command, it is detected whether the engine speed is zero and there is no torque output.

In order to further understand an engine starting method provided by an embodiment of the present application, the following details of steps in fig. 2 are described below:
in some possible embodiments, the user wants to start the engine again in a short time after turning off the engine, where the engine may not yet stop working, so after the user triggers the start command, it needs to detect whether the rotation speed of the engine is the case or whether there is torque output, if at this time the rotation speed of the engine is not zero and there is torque output, in order to avoid the engine from malfunctioning, it needs to wait for the engine to start after stopping working.
In some possible embodiments, when the battery power of the generator is low, in order to enable the engine to start successfully, the vehicle controller may appropriately reduce the engine start target rotation speed to save the battery power, so, after determining that the engine rotation speed is zero and no torque is output, the rotation speed threshold corresponding to the current battery power may be determined by implementing the steps shown in fig. 3, where:
in step 301: and obtaining the battery electric quantity of the generator.
In step 302: and determining a rotating speed threshold corresponding to the battery electric quantity according to the battery electric quantity and the relation between the preset rotating speed threshold and the battery electric quantity.
For example: the relationship between the preset rotation speed threshold and the battery power is shown in fig. 4, if the battery power corresponding to the engine is 35% at the moment, the rotation speed threshold corresponding to the battery power of 35% can be determined to be 1000 rpm according to the relationship between the rotation speed threshold and the battery power shown in fig. 4.
In some possible embodiments, after determining the rotation speed threshold corresponding to the battery power, controlling the generator to drag the engine to rotate until the rotation speed of the engine reaches the rotation speed threshold; after determining that the rotation speed of the engine reaches a rotation speed threshold value, acquiring the current water temperature of the engine, and determining a first duration according to the current water temperature; the determining the first time period according to the current water temperature may be specifically implemented as: and obtaining a first time length according to the corresponding relation between the preset water temperature and the time length and the current water temperature.
For example: the corresponding relation between the preset water temperature and the time length is shown in fig. 5, if the current water temperature is 30 ℃ at this time, the first time length corresponding to the current water temperature of 30 ℃ can be determined to be 7 seconds according to the corresponding relation between the water temperature and the time length shown in fig. 5.
In the embodiment of the application, the water temperature is inversely proportional to the first time, namely the lower the water temperature is, the longer the first time is, and when the temperature is lower, the success rate of engine starting is ensured by prolonging the oil injection ignition time of the engine.
In some possible embodiments, in order to avoid the waste of resources caused by the continuous fuel injection ignition after the start of the engine, it is necessary to implement, after the duration of the fuel injection ignition of the engine is equal to or longer than the first duration: determining whether the torque of the engine and the torque of the generator meet a preset relation; the method can be implemented as the steps shown in fig. 6, wherein:
in step 601: taking any one of the torque of the engine and the torque of the generator as a first torque; if the torque of the engine is the first torque, the torque of the generator is the second torque; if the torque of the generator is determined to be the first torque, the torque of the engine is determined to be the second torque.
In step 602: and performing a reversing operation on the first torque to obtain the opposite number of the first torque.
In step 603: and if the absolute value of the difference value between the opposite number of the first torque and the second torque is smaller than the difference value threshold value, determining that the torque of the engine and the torque of the generator meet the preset relation.
For example: taking the torque of the engine as a first torque, determining the torque of the engine as A, performing reverse operation on the torque A of the engine to obtain the reverse number-A of the first torque, determining the second torque as B, and determining the absolute value of the difference value between the first torque and the second torque as follows: and (3) determining that the absolute value of the difference between the torque of the engine and the torque of the generator is smaller than the difference threshold value if the difference threshold value is 0.5, and determining that the torque of the engine and the torque of the generator meet a preset relation.
In some possible embodiments, if it is determined that the torque of the engine and the torque of the generator meet the preset relationship, it is determined that the engine is started successfully, and it is required to control the engine to stop fuel injection and ignition. If it is determined that the torque of the engine and the torque of the generator do not satisfy the preset relationship, the steps shown in fig. 7 are implemented, in which:
in step 701: determining whether the second duration is greater than a time threshold; wherein the second time period is a time period between a time instant in response to the start instruction and the current time instant.
In step 702: if the second time period is determined to be greater than the time threshold, determining that the engine fails to start.
In step 703: and if the second duration is less than or equal to the time threshold, returning to the step of determining whether the torque of the engine and the torque of the generator meet the preset relation.
For example: the time threshold is 10 seconds, the second time length is 11 seconds, the second time length is larger than the time threshold, the engine start failure is determined, and at the moment, a prompt box of the engine start failure shown in fig. 8 can be popped up through the vehicle-mounted screen to inform a user of the engine start failure. After the failure of starting the engine is determined, the method can also inform the user of the failure of starting the engine in a voice broadcasting mode.
In order to facilitate further understanding of the engine starting method provided by the embodiment of the present application, the following describes in detail an overall flow of the engine starting method provided by the embodiment of the present application, as shown in fig. 9, in which:
in step 901: in response to a start instruction.
In step 902: it is detected whether the engine has a zero rotational speed and no torque output, if it is determined that the rotational speed is not zero and there is a torque output, step 901 is entered, otherwise step 903 is entered.
In step 903: and obtaining the battery electric quantity of the generator.
In step 904: and determining a rotating speed threshold corresponding to the battery electric quantity according to the battery electric quantity and the relation between the preset rotating speed threshold and the battery electric quantity.
In step 905: and controlling the generator to drag the engine to rotate until the rotating speed of the engine reaches a rotating speed threshold value.
In step 906: the current water temperature of the engine is obtained, and the first duration is determined according to the current water temperature.
In step 907: and controlling the duration of fuel injection ignition of the engine to be longer than or equal to the first duration.
In step 908: it is determined whether the engine is started successfully, if so, step 909 is entered, otherwise step 910 is entered.
In step 909: ending the starting process.
In step 910: determining whether the second duration is greater than a time threshold; wherein the second time period is a time period between a time instant in response to the start instruction and the current time instant. If yes, go to step 911, and if no, go to step 908.
In step 911: an engine start failure is determined.
