[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] In this application, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0049] Furthermore, in this document, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0050] As can be seen from the background art, in the prior art, when performing parking micro-regeneration carbon removal treatment, the temperature of the post-treatment system cannot be quickly increased, resulting in a poor effect of the parking micro-regeneration carbon removal treatment.

[0051] In view of this, the present application provides a parking micro-regeneration control method, device, electronic device and storage medium to solve the problem in the prior art that the temperature of the after-treatment system cannot be quickly increased, resulting in poor parking micro-regeneration carbon removal treatment effect.

[0052] This embodiment provides a control method for parking micro-regeneration, such as Figure 1 As shown, specifically including:

[0053] S101, when the vehicle enters the parking micro-regeneration mode, the vehicle operating parameters are obtained; wherein the vehicle operating parameters include carbon load, battery state of charge, engine water temperature and exhaust temperature;

[0054] It should be noted that this embodiment is for extended-range vehicles, whose engines are used as range extenders to generate electricity for the on-board battery modules. The user can trigger the parking micro-regeneration mode by pressing the parking power generation button. When the vehicle enters the parking micro-regeneration mode, the vehicle operating parameters such as carbon load, battery charge state, engine water temperature and exhaust temperature are obtained to determine whether the vehicle is currently suitable for the parking micro-regeneration mode.

[0055] S102: If the vehicle operating parameters meet the preset conditions, the engine is controlled to enter the power generation state.

[0056] It should be noted that if the vehicle operating parameters meet the preset conditions, parking micro-regeneration can be performed. At this time, the engine is controlled to enter the power generation state, and the engine operating load is increased to speed up the increase of exhaust temperature.

[0057] The preset conditions can be set according to the actual situation, such as the carbon load is greater than 3mg / s, the battery state of charge (SOC) is less than 40%, the engine water temperature is higher than 80℃, and the exhaust temperature is higher than 150℃. Among them, when the carbon load is greater than 3mg / s, it means that the carbon load is relatively large and micro-regeneration is required to eliminate carbon. SOC is lower than 40% to ensure that the engine has enough space to generate electricity during parking micro-regeneration. The engine water temperature is higher than 80℃ and the exhaust temperature is higher than 150℃ mainly to avoid the engine entering parking micro-regeneration after cold start. At this time, the temperature is too low and the effect of parking micro-regeneration will be relatively poor.

[0058] Optionally, in another embodiment of the present application, if the vehicle operating parameters do not meet the preset conditions, the parking micro-regeneration mode is automatically exited, and a prompt message that the parking micro-regeneration conditions are not met is generated to remind the user.

[0059] S103: adjusting the opening of the throttle valve and controlling the injection of hydrocarbon compounds based on the exhaust gas temperature.

[0060] It should be noted that increasing the engine load alone is not enough to increase the exhaust temperature. Therefore, the exhaust temperature can be increased by adjusting the throttle valve opening and controlling the injection of hydrocarbon compounds, such as holding the throttle valve, that is, reducing the throttle valve opening to increase the exhaust temperature. And injecting hydrocarbon compounds (HC for short) for combustion to increase the exhaust temperature. By these means, the exhaust temperature is increased to 400 degrees Celsius, at which time the carbon will gradually be eliminated and the carbon load will slowly decrease. Among them, the relevant components of parking micro-regeneration can be seen in Figure 2 Optionally, in another embodiment of the present application, an implementation of step S103 is as follows: Figure 3 As shown, this may include:

[0061] S301. Determine whether the exhaust temperature is less than a preset exhaust temperature threshold; wherein the exhaust temperature threshold is the ignition temperature of hydrocarbon compounds.

[0062] It should be noted that it is first determined whether the exhaust temperature is less than a preset exhaust temperature threshold; wherein the exhaust temperature threshold is the ignition temperature of hydrocarbon compounds, generally 280 degrees Celsius, that is, the ignition temperature of HC is 280 degrees Celsius, and HC cannot burn below 280 degrees Celsius.

[0063] S302: If the exhaust temperature is not less than the exhaust temperature threshold, the throttle valve opening is adjusted to a preset opening and the injection of hydrocarbon compounds is started; wherein the preset opening is less than the maximum opening of the throttle valve.

[0064] It should be noted that if the exhaust temperature is not less than the exhaust temperature threshold, i.e. 280 degrees Celsius, then the ignition temperature of hydrocarbon compounds has been reached at this time, so the throttle valve opening is reduced to a preset opening, such as 20%, to achieve throttle valve holding to increase the exhaust temperature, and at the same time, hydrocarbon compounds are injected to burn to increase the exhaust temperature. In this way, the exhaust temperature can be quickly increased to 400 degrees Celsius to regenerate and eliminate carbon.

[0065] S303: If the exhaust temperature is lower than the exhaust temperature threshold, the throttle valve opening is adjusted to a preset opening until the exhaust temperature is detected to be not lower than the exhaust temperature threshold, and then the injection of hydrocarbon compounds is started.

[0066] It should be noted that if the exhaust temperature is less than the exhaust temperature threshold, the ignition temperature of hydrocarbon compounds has not yet been reached, so the throttle valve opening is first reduced to a preset opening, such as 20%, to hold the throttle valve to increase the exhaust temperature until the temperature reaches 280 degrees Celsius. Then the injection of hydrocarbon compounds is turned on to cause combustion to increase the exhaust temperature.

[0067] S104: When it is detected that the carbon load is lower than a preset first carbon load threshold or the battery state of charge reaches a preset power threshold, exit the parking micro-regeneration mode.

[0068] It should be noted that when the carbon load is detected to be lower than the preset first carbon load threshold, such as 2 mg / s, the carbon load has been significantly reduced, so the parking micro-regeneration mode can be exited to stop carbon regeneration and elimination. Or the battery state of charge reaches a preset power threshold, such as 95%, indicating that the power is high and is almost full, and the engine does not need to continue to generate electricity. It is necessary to exit the parking micro-regeneration mode in time to end the engine's power generation state.

[0069] Optionally, in another embodiment of the present application, an implementation of exiting the parking micro-regeneration mode in step S104 may include:

[0070] Adjust the throttle valve opening to the maximum opening;

[0071] gradually reducing the injection amount of hydrocarbon compounds at a preset speed until the injection amount reaches 0;

[0072] Control the engine to exit the power generation state.

[0073] It should be noted that when exiting the parking micro-regeneration mode, the throttle valve opening is adjusted to the maximum opening to end the throttle valve holding state. At the same time, the injection amount of hydrocarbon compounds is gradually reduced at a preset speed until the injection amount is 0, for example, the injection amount is reduced by 10% per second until the injection is completely stopped. Finally, the engine is controlled to exit the power generation state and turn to idle or shut down.

[0074] Optionally, in another embodiment of the present application, the above parking micro-regeneration control method may further include:

[0075] When the vehicle is in a driving state, if it is detected that the carbon load is greater than a preset second carbon load threshold, the vehicle power conservation mode is triggered; wherein the vehicle power conservation mode is used to control the battery charge state of the vehicle to reach the power threshold.

[0076] It should be noted that when the vehicle is in a driving state, if the carbon load is detected to be greater than the preset second carbon load threshold, such as 3 mg / s, it means that the carbon load is high and needs to be regenerated. In order to ensure that there is enough power to run in the parking micro-regeneration mode, the vehicle power conservation mode is triggered to control the battery state of charge of the vehicle to reach the power threshold, such as keeping the SOC at 30%.

[0077] In a parking micro-regeneration control method provided in an embodiment of the present application, when the vehicle enters the parking micro-regeneration mode, the vehicle operating parameters are obtained. If the vehicle operating parameters meet the preset conditions, the engine is controlled to enter the power generation state to accelerate the increase in exhaust temperature. Then, the opening of the throttle valve is adjusted based on the exhaust temperature and the injection of hydrocarbon compounds is controlled to perform thermal management, and the exhaust temperature is further accelerated to reach a temperature that can achieve carbon regeneration and elimination. When it is detected that the carbon load is lower than a preset first carbon load threshold or the battery state of charge reaches a preset power threshold, the parking micro-regeneration mode is exited. It can be seen that by using the method of the present application, the exhaust temperature can be quickly increased during parking micro-regeneration, thereby improving the effect of parking micro-regeneration carbon elimination treatment. The problem that the temperature of the post-treatment system cannot be quickly increased in the prior art, resulting in poor effect of parking micro-regeneration carbon elimination treatment, is solved.

[0078] Another embodiment of the present application also provides a control device for parking micro-regeneration, such as Figure 4 As shown, including:

[0079] The acquisition unit 401 is used to acquire vehicle operating parameters when the vehicle enters the parking micro-regeneration mode; wherein the vehicle operating parameters include carbon load, battery charge state, engine water temperature and exhaust temperature.

[0080] The first control unit 402 is used to control the engine to enter a power generation state if the vehicle operating parameters meet preset conditions.

[0081] The second control unit 403 is used to adjust the opening of the throttle valve and control the injection of hydrocarbon compounds based on the exhaust temperature.

[0082] The detection unit 404 is used to exit the parking micro-regeneration mode when it is detected that the carbon load is lower than a preset first carbon load threshold or the battery charge state reaches a preset power threshold.

[0083] In this embodiment, the specific execution process of the acquisition unit 401, the first control unit 402, the second control unit 403 and the detection unit 404 can be referred to the corresponding Figure 1 The content of the method embodiment will not be repeated here.

[0084] In a parking micro-regeneration control device provided in an embodiment of the present application, when the vehicle enters the parking micro-regeneration mode, the acquisition unit 401 acquires the vehicle operating parameters. If the vehicle operating parameters meet the preset conditions, the first control unit 402 controls the engine to enter the power generation state to accelerate the increase of the exhaust temperature. Then the second control unit 403 adjusts the opening of the throttle valve and controls the injection of hydrocarbon compounds based on the exhaust temperature to perform thermal management, and further accelerates the increase of the exhaust temperature so that it reaches a temperature that can achieve carbon regeneration and elimination. When the detection unit 404 detects that the carbon load is lower than the preset first carbon load threshold or the battery charge state reaches the preset power threshold, the parking micro-regeneration mode is exited. It can be seen that by using the method of the present application, the exhaust temperature can be quickly increased during parking micro-regeneration, thereby improving the effect of parking micro-regeneration carbon elimination treatment. It solves the problem that the temperature of the post-treatment system cannot be quickly increased in the prior art, resulting in poor effect of parking micro-regeneration carbon elimination treatment.

[0085] Optionally, in another embodiment of the present application, an implementation of the second control unit 403 may include:

[0086] The determination subunit is used to determine whether the exhaust temperature is less than a preset exhaust temperature threshold; wherein the exhaust temperature threshold is the ignition temperature of hydrocarbon compounds.

[0088] The second control subunit is used to adjust the opening of the throttle valve to a preset opening if the exhaust temperature is less than the exhaust temperature threshold, and then start the injection of hydrocarbon compounds until the exhaust temperature is detected to be not less than the exhaust temperature threshold.

[0089] In this embodiment, the specific execution process of the determination subunit, the first control subunit and the second control subunit can be referred to in the corresponding Figure 3 The content of the method embodiment will not be repeated here.

[0093] The fourth control subunit is used to control the engine to exit the power generation state.

[0094] In this embodiment, the specific execution process of the regulating subunit, the third control subunit and the fourth control subunit can be found in the corresponding method embodiments described above, and will not be repeated here.
