Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a parking regeneration control method, device, and vehicle. Background Technology

[0002] With increasingly stringent emission standards, DPF (Diesel Particulate Filter) has become a standard exhaust treatment device in China VI compliant engines. Parking regeneration, a common carbon removal method, significantly impacts user experience due to its fuel consumption and noise levels. Currently, there is no distinction between the thermal management of parking and driving regeneration, resulting in incomplete utilization of regeneration thermal management capabilities. Furthermore, even under ideal temperature conditions, the regeneration speed cannot be reduced accordingly, leading to high fuel consumption and noise during parking regeneration, severely affecting the user experience. In extreme environments, the regeneration speed and energy cannot be increased accordingly, resulting in regeneration failure. Summary of the Invention

The control method creates a new parking regeneration thermal management mode and parking regeneration intelligent control model for the parking regeneration working conditions. It analyzes and judges the conditions during parking regeneration, and reduces fuel consumption and noise during parking regeneration, reduces regeneration costs, and improves user experience while ensuring successful regeneration.

[0010] By using engine bench tests to simulate different engine operating conditions, a parking regeneration thermal management mode and a parking regeneration intelligent control model were established.

[0011] Optionally, the operating parameters include the ambient temperature and the temperature rise rate of the oxidizing catalyst within a preset time period.

[0012] Optionally, engine bench tests can be used to simulate different engine operating conditions to establish a parking regenerative thermal management mode and a parking regenerative intelligent control model, including:

[0013] Using an engine simulated step test to simulate parking regeneration load, starting from the highest regeneration speed N, which is the easiest to complete parking regeneration. Hi Gradually reduce the engine speed until it reaches the minimum regeneration speed N required for parking regeneration. Low At each engine speed, combustion parameters are adjusted to improve thermal management, while simultaneously considering parking regeneration time, ensuring the engine operates at N... Hi ~N Low All speeds meet the parking regeneration requirements, and a parking regeneration thermal management mode is established;

[0014] By simulating different ambient temperatures using an engine step test, the temperature rise rate of the oxidized catalyst at each parking regeneration speed under different ambient temperatures was recorded, along with the corresponding regeneration time. This established the correlation between ambient temperature, the temperature rise rate of the oxidized catalyst, and the parking regeneration speed, as well as the correlation between ambient temperature, the temperature rise rate of the oxidized catalyst, and the parking regeneration time.

[0015] Optionally, the combustion parameters include throttle valve opening, advance angle, and fuel injection quantity.

[0016] Optionally, based on the operating parameters and the parking regeneration intelligent control model, the parking regeneration speed and parking regeneration duration are determined, including:

[0017] If the ambient temperature is greater than the first preset threshold and the temperature rise rate of the oxidizing catalyst is greater than the second preset threshold, the parking regeneration speed will be reduced according to the parking regeneration intelligent control model.

[0018] Optionally, based on the operating parameters and the parking regeneration intelligent control model, determining the parking regeneration speed and parking regeneration duration further includes:

[0019] If the ambient temperature is less than or equal to the first preset threshold, or the temperature rise rate of the oxidizing catalyst is less than or equal to the second preset threshold, then the parking regeneration speed is increased and the parking regeneration time is shortened according to the parking regeneration intelligent control model.

[0020] Optionally, after obtaining the operating status of the particulate filter and determining whether the vehicle requires regeneration while parked, the following steps are also included:

[0021] If not, the working status of the particulate filter will be retrieved again after a preset time to determine whether the vehicle requires regeneration while parked.

[0022] According to another aspect of the present invention, a parking regeneration control device is provided, comprising:

[0023] The judgment module is used to obtain the working status of the particulate filter and determine whether the vehicle needs to be parked for regeneration.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0036] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0037] Figure 1 This is a flowchart illustrating a parking regeneration control method according to an embodiment of the present invention. (Refer to...) Figure 1 The parking regeneration control method provided in this embodiment includes:

[0038] S110. Obtain the working status of the particulate filter and determine whether the vehicle needs to be regenerated while parked.

[0039] Particulate filters (DPFs) are part of a vehicle's low-emission aftertreatment system, used to filter particulate matter from engine exhaust. The main component of a DPF is the filter media, which is primarily classified into two categories based on material: ceramic-based and metal-based. Ceramic-based DPF media materials include cordierite, silicon carbide, mullite, and zirconium oxide; metal-based DPF media materials include sintered metal, metal foam, and metal mesh. Currently, cordierite and silicon carbide are the most commonly used filter media materials. DPF designs include wall-flow and fluid-flow types, with wall-flow being the most common. This type of DPF typically uses a cylindrical ceramic structure with numerous small, parallel channels along the axial direction. Unlike typical flow-through filters, wall-flow filter structures selectively block one end of the adjacent channels in the filter layer, forcing exhaust gas through the porous wall surface to capture particulate matter. The operating status of the DPF includes the carbon load of the particulate filter. When the carbon load in the DPF reaches a certain limit, the driver needs to press the regeneration switch while the vehicle is parked to manually trigger the combustion of particulate matter for regeneration, which is called parking regeneration.

[0040] If so, S120, execute parking regeneration and enter parking regeneration thermal management mode.

[0041] S130. Obtain the operating parameters for entering the parking regeneration thermal management mode, and determine the parking regeneration speed and parking regeneration duration based on the operating parameters and the parking regeneration intelligent control model.

[0042] The parking regeneration intelligent control model includes the correspondence between operating parameters and parking regeneration speed, as well as the correspondence between operating parameters and parking regeneration duration.

[0043] Optionally, the operating parameters include the ambient temperature and the temperature rise rate of the oxidizing catalyst within a preset time period. The parking regeneration intelligent control model can be calibrated using engine bench tests, and the specific calibration can be based on the actual engine model; this embodiment of the invention does not limit this.

[0044] The control method of this invention creates a brand-new parking regeneration thermal management mode and parking regeneration intelligent control model for the parking regeneration working conditions. It analyzes and judges the conditions during parking regeneration, and reduces fuel consumption and noise during parking regeneration, reduces regeneration costs, and improves user experience while ensuring successful regeneration.

[0045] Optional, continue to refer to Figure 1 After obtaining the working status of the particulate filter in S110 and determining whether the vehicle requires parking regeneration, the following steps are also included:

[0046] If not, S140, after a preset time, obtain the working status of the particulate filter again to determine whether the vehicle has a parking regeneration requirement.

[0047] The specific preset time can be set according to the actual situation. When there is a need for parking regeneration, S120 and S130 will be executed.

[0048] Figure 2 This is a schematic flowchart of another parking regeneration control method provided in an embodiment of the present invention, referred to... Figure 2 The parking regeneration control method includes:

[0049] S210. Using engine bench tests to simulate different engine operating conditions, establish a parking regeneration heat management mode and a parking regeneration intelligent control model.

[0050] Optionally, engine bench tests can be used to simulate different engine operating conditions to establish a parking regenerative thermal management mode and a parking regenerative intelligent control model, including:

[0051] Using an engine simulated step test to simulate parking regeneration load, starting from the highest regeneration speed N, which is the easiest to complete parking regeneration. Hi Gradually reduce the engine speed until it reaches the minimum regeneration speed N required for parking regeneration. Low At each engine speed, combustion parameters are adjusted to improve thermal management, while simultaneously considering parking regeneration time, ensuring the engine operates at N... Hi ~N Low All speeds meet the parking regeneration requirements, and a parking regeneration thermal management mode is established;

[0052] By simulating different ambient temperatures using an engine step test, the temperature rise rate of the oxidized catalyst at each parking regeneration speed under different ambient temperatures was recorded, along with the corresponding regeneration time. This established the correlation between ambient temperature, the temperature rise rate of the oxidized catalyst, and the parking regeneration speed, as well as the correlation between ambient temperature, the temperature rise rate of the oxidized catalyst, and the parking regeneration time.

[0053] During engine development on a standard test bench, the intake manifold was installed correctly with no leaks, fuel injection was normal, all engine combustion parameters were normal, and the aftertreatment system was normal. In parking regeneration mode, where user power requirements are low, optional combustion parameters include throttle opening, advance angle, and fuel injection quantity. The process of establishing the parking regeneration thermal management mode is as follows: starting from the highest regeneration speed N, where regeneration is most easily completed... Hi Gradually reduce the engine speed until it reaches the minimum regeneration speed N that can meet the requirements of parking regeneration. Low At various engine speeds, thermal management is improved by adjusting combustion parameters such as throttle valve opening, advance angle, and fuel injection quantity, while simultaneously considering parking regeneration time to enhance engine N250N ... Hi ~N Low All speeds meet the parking regeneration requirements, a parking regeneration thermal management mode is established, and this mode is stored in the engine electronic control unit (ECU).

[0054] Diesel oxidation catalysts (DOC) are used to convert CO (carbon monoxide) and HC (hydrocarbons) in waste into harmless CO2 (carbon dioxide) and H2O (water), and to convert NO (nitric oxide) into NO2 (nitric oxide). The process of establishing a parking regeneration intelligent control model involves: during development testing, simulating different ambient temperatures, recording the DOC temperature rise rate at each parking regeneration speed under different ambient temperatures, and recording the corresponding regeneration time. This establishes the correspondence between ambient temperature, DOC temperature rise rate, and parking regeneration speed, as well as the correspondence between ambient temperature, DOC temperature rise rate, and parking regeneration time. These two sets of correspondences are then stored in the ECU.

[0055] S210. Obtain the working status of the particulate filter and determine whether the vehicle needs to be regenerated while parked.

[0056] If so, S230, execute parking regeneration and enter parking regeneration thermal management mode.

[0057] If not, S250 will retrieve the working status of the particulate filter again after a preset time to determine whether the vehicle needs to be parked for regeneration.

[0058] S240. Obtain the operating parameters for entering the parking regeneration thermal management mode, and determine the parking regeneration speed and parking regeneration duration based on the operating parameters and the parking regeneration intelligent control model.

[0059] It is understood that the subsequent steps are the same as those in the aforementioned embodiments, and will not be described in detail here.

[0060] Optionally, based on operating parameters and the parking regeneration intelligent control model, the parking regeneration speed and parking regeneration duration are determined, including:

[0061] If the ambient temperature is greater than the first preset threshold and the temperature rise rate of the oxidizing catalyst is greater than the second preset threshold, the parking regeneration speed will be reduced according to the parking regeneration intelligent control model.

[0062] Optionally, based on operating parameters and the parking regeneration intelligent control model, the parking regeneration speed and parking regeneration duration are determined, and the following are also included:

[0063] If the ambient temperature is less than or equal to the first preset threshold, or the temperature rise rate of the oxidizing catalyst is less than or equal to the second preset threshold, the parking regeneration speed will be increased and the parking regeneration time will be shortened according to the parking regeneration intelligent control model.

[0064] In specific implementation, the first preset threshold and the second preset threshold can be designed according to the actual situation, and the embodiments of the present invention do not limit this. For example, the second preset threshold can be a DOC temperature increase of greater than or equal to 5°C in 1 second, or a DOC temperature increase of greater than or equal to 30°C in 3 minutes, or a DOC temperature increase of greater than or equal to 50°C in 5 minutes.

[0065] When a parking regeneration request is detected, the engine switches to parking regeneration thermal management mode. As parking regeneration begins, the ambient temperature and DOC temperature rise rate are monitored for a certain period of time. By comparing the ambient temperature and DOC temperature rise rate in the parking regeneration intelligent control model, an appropriate parking speed is intelligently selected: when the temperature conditions are favorable (ambient temperature is greater than the first preset threshold, and the temperature rise rate of the oxidizing catalyst is greater than the second preset threshold), the parking regeneration speed is reduced to save fuel and reduce noise. When the temperature conditions are unfavorable (ambient temperature is less than or equal to the first preset threshold, or the temperature rise rate of the oxidizing catalyst is less than or equal to the second preset threshold), priority is given to ensuring successful regeneration and shortening the regeneration time.

[0066] After receiving a parking regeneration request, the ECU enters the parking regeneration thermal management mode. Once stable in this mode, the parking regeneration intelligent control model assesses the current DOC temperature rise and ambient temperature. If the temperature rise is rapid and the temperature conditions are favorable, the model reduces the parking regeneration speed to save fuel, reduce noise, and improve the user experience. If the temperature rise is slow and the temperature conditions are unfavorable, the regeneration speed is increased to prioritize completing parking regeneration and shorten the regeneration time under adverse conditions.

[0067] Figure 3 This is a schematic diagram of a parking regeneration control device provided in an embodiment of the present invention, with reference to... Figure 3 The parking regeneration control device includes:

[0068] The judgment module 10 is used to obtain the working status of the particulate filter and determine whether the vehicle has a parking regeneration requirement; the parking regeneration thermal management module 20 is used to execute parking regeneration and enter the parking regeneration thermal management mode when the judgment module determines that there is a parking regeneration requirement; the parking regeneration execution module 30 is used to obtain the operating parameters for entering the parking regeneration thermal management mode, and determine the parking regeneration speed and parking regeneration duration based on the operating parameters and the parking regeneration intelligent control model; wherein, the parking regeneration intelligent control model includes the correspondence between operating parameters and parking regeneration speed and the correspondence between operating parameters and parking regeneration duration.

[0069] The parking regeneration control device provided in this embodiment of the invention is used to execute any of the parking regeneration control methods provided in the above embodiments, has a corresponding execution module, and has the same or corresponding technical effects.

[0070] Optionally, the judgment module 10 is also used to obtain the working status of the particulate filter again after a preset time when it is determined that there is no need for parking regeneration, and to determine again whether the vehicle has a need for parking regeneration.

[0071] Optionally, the parking regeneration control device also includes a storage module. The storage module is used to store the parking regeneration thermal management mode and the parking regeneration intelligent control model when using engine bench tests to simulate different engine operating conditions and establish the parking regeneration thermal management mode and the parking regeneration intelligent control model. The specific storage module can be built into the ECU.

[0072] Optionally, the parking regeneration execution module 30 is specifically used to reduce the parking regeneration speed according to the parking regeneration intelligent control model if the ambient temperature is greater than the first preset threshold and the temperature rise rate of the oxidizing catalyst is greater than the second preset threshold; and to increase the parking regeneration speed and shorten the parking regeneration time according to the parking regeneration intelligent control model if the ambient temperature is less than or equal to the first preset threshold or the temperature rise rate of the oxidizing catalyst is less than or equal to the second preset threshold.

[0073] Based on the same inventive concept, embodiments of the present invention also provide a vehicle including the parking regeneration control device provided in the above embodiments, wherein the parking regeneration control device is used to execute any of the parking regeneration control methods provided in the above embodiments.

[0074] For example, Figure 4 This is a partial structural diagram of a vehicle provided in an embodiment of the present invention, with reference to... Figure 4 The vehicle includes an intake manifold 1, a turbocharger 2, an engine 3, an ECU 4, an ambient temperature sensor 5, a DOC 6, a DPF 7, and an SCR (Selective Catalytic Reduction) system 8. The ECU 4 stores a parking regeneration thermal management mode and a parking regeneration intelligent control model. When the ECU 4 receives a parking regeneration signal (which can be triggered by the user to activate the parking regeneration switch), it enters the parking regeneration thermal management mode. As the parking regeneration state begins, it monitors the ambient temperature and the DOC 6 temperature rise rate over a certain period. By comparing the ambient temperature and DOC 6 temperature rise rate in the parking regeneration intelligent control model, it intelligently selects an appropriate parking speed: when temperature conditions are favorable, it reduces the parking regeneration speed to save fuel and reduce noise; when temperature conditions are unfavorable, it prioritizes successful regeneration and shortens the regeneration time.
