Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle control, and in particular to a vehicle, a parking regeneration control method and device thereof, and a storage medium. BACKGROUND

[0002] A gasoline particulate filter (GPF) is installed in the emission system of a direct injection gasoline engine to reduce particulate matter emissions of the gasoline engine and reduce pollution to the environment. The GPF is a wall-flow structure that traps soot particles in the exhaust gas on the wall surface to achieve the purpose of removing soot, however, the continuous accumulation of soot particles can cause the GPF to be blocked, causing the exhaust back pressure to rise, the engine fuel economy to deteriorate, and other problems.

[0003] In order to restore the filtering function of the GPF, periodic regeneration of the GPF filled with soot particles is required. Currently, there are two ways of GPF regeneration, on-road regeneration and parking regeneration. When the user cannot meet the long-time high-speed driving or the carbon particles in the particulate trap are too many, if on-road regeneration is performed again, there is a risk of burning the GPF, at this time, the parking regeneration mode in the 4S store is often used for regeneration.

[0004] Currently, the parking regeneration mode is generally to activate the parking regeneration through a diagnostic instrument, control the engine to be raised to a high idle condition, delay the ignition advance angle, reduce the lean air-fuel ratio, and increase the oxygen flow in the particulate trap to increase the temperature inside the particulate trap, so that the soot particles burn until the regeneration is completed. However, in this way, the engine operating condition of parking regeneration is a single high idle condition, which cannot meet the needs of different customers and 4S stores for regeneration time and fuel consumption, and the fuel consumption and time of parking regeneration are uncontrollable.

[0048] In order to make the personnel in the technical field better understand the present application scheme, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments.

It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0050] Embodiment one

[0051] Figure 1 A flow chart of a vehicle parking regenerative control method provided for the first embodiment of the present application, the present embodiment can be applicable to the case of controlling the parking regenerative process of the vehicle, the method can be executed by the parking regenerative control device of the vehicle, the control device can be realized in the form of hardware and / or software, and the control device can be configured in the controller of the vehicle. As shown in the figure, the method comprises: Figure 1

[0052] S110, when the vehicle responds to the parking regenerative request, display a plurality of parking regenerative modes for user selection.

[0053] ​The parking regeneration modes include at least two of a shortest time parking regeneration mode, a balanced parking regeneration mode and a lowest fuel consumption parking regeneration mode. It should be noted that the time required for the shortest time parking regeneration mode < the time required for the balanced parking regeneration mode < the time required for the lowest fuel consumption parking regeneration mode. Since shortening the time required for parking regeneration will inevitably result in an increase in fuel consumption per unit time, the fuel consumption required for the shortest time parking regeneration mode > the fuel consumption required for the balanced parking regeneration mode > the fuel consumption required for the lowest fuel consumption parking regeneration mode. The display of the plurality of parking regeneration modes can be, but is not limited to, displaying the plurality of parking regeneration modes through a vehicle diagnostic instrument or displaying the plurality of parking regeneration modes through an instrument system of the vehicle, etc.

[0054] It can be understood that during driving, the particulate trap installed in the exhaust system of the gasoline engine of the vehicle will continuously accumulate carbon particles. When the amount of accumulated carbon particles reaches a certain degree, the instrument system of the vehicle will prompt the user to take the vehicle to a service station 4S store for parking regeneration to remove the accumulated carbon particles in the particulate trap and thus restore the function of the particulate trap. After the vehicle is taken to the 4S store, the service personnel connect to the vehicle through a vehicle diagnostic instrument and send a parking regeneration request through a CAN line. When the vehicle meets the parking regeneration conditions, the vehicle will respond to the parking regeneration request sent by the vehicle diagnostic instrument. Exemplarily, the parking regeneration conditions can include that the engine raises the water temperature of the engine to above 70°C through warm-up, the gear of the vehicle is in neutral, the engine hood is open to improve the heat dissipation capacity, and other conditions that should be met during parking regeneration.

[0055] S120, determining an idle parameter of the engine of the vehicle according to the parking regeneration mode selected by the user.

[0056] The idle parameter of the engine of the vehicle can include, but is not limited to, an idle speed of the engine, a retardation ignition angle parameter of the engine and an air-fuel ratio parameter of the engine, etc. The idle parameter of the engine of the vehicle corresponding to different parking regeneration modes selected by the user is also different. In an exemplary embodiment, the shortest time parking regeneration mode requires the shortest time, and thus the efficiency of parking regeneration can be improved by increasing the idle speed of the engine and / or increasing the air-fuel ratio parameter of the engine, etc.

[0057] S130, controlling a parking regeneration process of the vehicle according to the idle parameter of the engine.

[0058] Specifically, when the vehicle responds to the request for parking regeneration, at least two of the shortest time parking regeneration mode, the balanced parking regeneration mode and the lowest fuel consumption parking regeneration mode are displayed, so that the user can select a suitable parking regeneration mode according to the demand for the time and fuel consumption required for parking regeneration; after the user selects the parking mode, the engine idle speed parameter of the vehicle is determined according to the parking regeneration mode selected by the user, so as to adjust the parameters of the engine of the vehicle to be the same as the idle speed parameter, thereby controlling the parking regeneration process of the vehicle.

[0059] In the embodiment, when the vehicle responds to the request for parking regeneration, a plurality of parking regeneration modes are displayed, so that the user can select a suitable parking regeneration mode according to the demand for the time and fuel consumption required for parking regeneration, and then determine the idle speed parameter of the engine of the vehicle according to the parking regeneration mode selected by the user, thereby controlling the parking regeneration process of the vehicle, so that the time and fuel consumption required for parking regeneration of the vehicle are controllable, when the user has a higher demand for saving time, the shortest time parking regeneration mode can be selected to make the time required for parking regeneration shortest, and when the user has a higher demand for saving fuel, the lowest fuel consumption parking regeneration mode can be selected; in addition, the controllability of the time and fuel consumption required for parking regeneration of the vehicle also enables the 4S store to reasonably arrange the time of different customers according to the time required for parking regeneration of the vehicle, thereby reducing the waiting time of the customers and improving the satisfaction of the customers with the service.

[0060] Embodiment two

[0061] Figure 2 A flowchart of a parking regeneration control method of a vehicle provided by the second embodiment of the application, the embodiment further adds the steps of judging whether to respond to the request for parking regeneration and how to determine the idle speed parameter of the engine according to the parking regeneration mode selected by the user when the request for parking regeneration is obtained on the basis of the above-mentioned embodiment.

[0062] When the vehicle is parking, the step of judging whether to exit the parking regeneration is added. Figure 2 As shown in the figure, the method specifically comprises:

[0063] S210, obtaining the request for parking regeneration in real time.

[0064] When the particulate filter of the vehicle needs parking regeneration, the service personnel of the 4S store can connect to the vehicle through the vehicle diagnostic instrument, and then send the request for parking regeneration through the CAN line.

[0065] S220, obtaining the first parameter information of the vehicle when the request for parking regeneration is obtained.

[0066] The first parameter information at least includes the current water temperature of the engine, the speed of the vehicle, the gear of the vehicle and the throttle travel of the vehicle.

[0067] S230, determining whether the first parameter information meets the stationary regeneration condition; if yes, performing S240.

[0068] The stationary regeneration condition includes that the current water temperature of the engine is greater than a preset water temperature, the speed of the vehicle is zero, the gear of the vehicle is neutral, and the throttle stroke of the vehicle is zero. The preset water temperature can be the lowest water temperature that can realize stationary regeneration set by the developer before the vehicle is shipped; in an exemplary embodiment, the preset water temperature can be 60℃; in other exemplary embodiments, the preset water temperature can also be 70℃. Since the vehicle needs to be set to an idle state when performing stationary regeneration, the speed of the vehicle needs to be controlled to be zero, the gear of the vehicle needs to be controlled to be neutral, and the throttle stroke of the vehicle needs to be controlled to be zero.

[0069] S240, controlling the vehicle to respond to the stationary regeneration request.

[0070] Specifically, when the stationary regeneration request is sent through the CAN line through the vehicle diagnostic instrument, the first parameter information of the vehicle is obtained, it is determined whether the first parameter information meets the stationary regeneration condition, and when the first parameter information meets the stationary regeneration condition, the vehicle is controlled to respond to the stationary regeneration request, so that after the user selects the stationary regeneration mode, the vehicle is controlled to perform stationary regeneration.

[0071] S250, displaying a plurality of stationary regeneration modes for the user to select when the vehicle responds to the stationary regeneration request.

[0072] The stationary regeneration mode includes at least two of the shortest time stationary regeneration mode, the balanced stationary regeneration mode, and the lowest fuel consumption stationary regeneration mode.

[0073] S260, determining the idle parameter of the engine of the vehicle according to the stationary regeneration mode selected by the user.

[0074] S270, controlling the stationary regeneration process of the vehicle according to the idle parameter of the engine.

[0075] S280, obtaining the second parameter information of the vehicle in real time.

[0076] The second parameter information includes the temperature of the particulate filter in the vehicle, the remaining soot amount of the particulate filter, the brake pedal stroke of the vehicle, and the throttle stroke of the vehicle.

[0077] S290, determining whether the second parameter information meets the stationary regeneration exit condition; if yes, performing S2100.

[0078] The parking regeneration exit condition includes at least one of the following: the temperature of the particulate filter is greater than a preset temperature, the residual soot amount of the particulate filter is less than a preset soot amount, the brake pedal stroke of the vehicle is greater than zero, and the throttle stroke of the vehicle is greater than zero. The preset temperature can be a temperature set by a developer of the vehicle before leaving the factory, which is not greater than the normal use temperature of the particulate filter, for example, the preset temperature can be the maximum temperature at which the particulate filter can be normally used for a long time; in an exemplary embodiment, the preset temperature can be 800℃. The preset soot amount can be a soot amount set by the developer of the vehicle before leaving the factory according to the minimum amount of carbon particles remaining in the particulate filter after parking regeneration; in an exemplary embodiment, when the residual soot amount of the particulate filter is less than the preset soot amount, the carbon particles in the particulate filter cannot continue to burn. When the brake pedal stroke of the vehicle is greater than zero and / or the throttle stroke of the vehicle is greater than zero, the parking regeneration condition will not be met, and parking regeneration needs to be stopped. In an exemplary embodiment, when the user currently selected parking regeneration mode no longer meets his needs, the parking regeneration process in the current parking regeneration mode can be interrupted by stepping on the brake pedal of the vehicle to make the brake pedal stroke of the vehicle greater than zero, or by stepping on the throttle of the vehicle to make the throttle stroke of the vehicle greater than zero, so as to reselect the corresponding parking regeneration mode according to the needs.

[0079] S2100, controlling the vehicle to exit the parking regeneration mode.

[0080] Specifically, in the process of parking regeneration of the vehicle, the second parameter information of the vehicle is acquired in real time to determine whether the second parameter information meets the parking regeneration exit condition. When the second parameter information meets the parking regeneration exit condition, the vehicle is controlled to exit the parking regeneration mode to interrupt the parking regeneration in the current parking regeneration mode.

[0081] S2110, determining whether the residual soot amount of the particulate filter is less than a preset soot amount; if yes, performing S2120, and if no, returning to perform S230.

[0082] S2120, issuing a reminder of completion of parking regeneration.

[0083] The reminder of completion of parking regeneration can be displayed by the display screen of the vehicle diagnostic instrument with the words related to "parking regeneration completed", or displayed by the instrument system of the vehicle, and in other embodiments, the reminder of completion of parking regeneration can also be given by sound prompt, and the embodiment does not limit the way of the reminder of completion of parking regeneration.

[0084] Specifically, after the vehicle exits the parking regeneration mode, whether the remaining soot amount of the particulate filter is less than the preset soot amount is judged. When the remaining soot amount of the particulate filter is less than the preset soot amount, it indicates that the parking regeneration is completed, and a reminder of the completion of the parking regeneration can be given. When the remaining soot amount of the particulate filter is greater than or equal to the preset soot amount, it indicates that the parking regeneration is not completed, and thus the step of judging whether the first parameter information satisfies the parking regeneration condition is returned to. When the first parameter information again satisfies the parking regeneration condition, the parking regeneration request is responded to again, and the parking regeneration mode is displayed again for the user to select a parking regeneration mode that meets the user's demand, so as to control the parking regeneration process of the vehicle.

[0085] In the embodiment, when the parking regeneration request is acquired, the first parameter information of the vehicle is acquired to judge whether the first parameter information satisfies the parking regeneration condition, and when the first parameter information satisfies the parking regeneration condition, the vehicle is controlled to respond to the parking regeneration request, so that the vehicle responds to the parking regeneration request only when the parking regeneration condition is satisfied, thereby ensuring that the carbon particles in the particulate filter can be quickly oxidized when the vehicle is parked and regenerated, and the purpose of removing the carbon particles is achieved. Meanwhile, during the parking regeneration of the vehicle, the second parameter information of the vehicle is acquired in real time to judge whether the second parameter information satisfies the parking regeneration exit condition, and when the second parameter information satisfies the parking regeneration exit condition, the vehicle is controlled to exit the parking regeneration mode to interrupt the parking regeneration in the current parking regeneration mode. After the vehicle exits the parking regeneration mode, whether the remaining soot amount of the particulate filter is less than the preset soot amount is judged. When the remaining soot amount of the particulate filter is less than the preset soot amount, it indicates that the parking regeneration is completed, and a reminder of the completion of the parking regeneration can be given. When the remaining soot amount of the particulate filter is greater than or equal to the preset soot amount, it indicates that the parking regeneration is not completed, and thus the step of judging whether the first parameter information satisfies the parking regeneration condition is returned to. When the first parameter information again satisfies the parking regeneration condition, the parking regeneration request is responded to again, and the parking regeneration mode is displayed again for the user to select a parking regeneration mode that meets the user's demand, so as to control the parking regeneration process of the vehicle.

[0093] Specifically, when the request for parking regeneration is obtained, the remaining soot amount of the particulate filter is obtained to determine the time required and the fuel consumption required for completing the parking regeneration corresponding to each parking regeneration mode according to the remaining soot amount of the particulate filter and each parking regeneration mode, so that in response to the request for parking regeneration, a plurality of parking regeneration modes are displayed, and the time required and the fuel consumption required for completing the parking regeneration corresponding to each parking regeneration mode are displayed, so that the user can select a parking regeneration mode meeting the user's own demand according to the user's own demand for the time required and the fuel consumption required for parking regeneration, and refer to the time required and the fuel consumption required for completing the parking regeneration corresponding to each parking regeneration mode.

[0094] S340, determining the idle parameters of the engine of the vehicle according to the parking regeneration mode selected by the user.

[0096] In an optional embodiment, according to the user-selected parking regeneration mode, determining the engine idle parameter comprises: when the user selects the shortest time parking regeneration mode, determining the engine idle parameter as engine idle speed = A1, retarded ignition angle parameter = B1, and air-fuel ratio parameter = C1; when the user selects the balanced parking regeneration mode, determining the engine idle parameter as engine idle speed = A2, retarded ignition angle parameter = B2, and air-fuel ratio parameter = C2; when the user selects the lowest fuel consumption parking regeneration mode, determining the engine idle parameter as engine idle speed = A3, retarded ignition angle parameter = B3, and air-fuel ratio parameter = C3; wherein A1 > A2 > A3; B1 > B2 > B3; and C1 > C2 > C3, so that when the user selects the lowest time parking regeneration mode, the parking regeneration time is the shortest, and correspondingly, when the user selects the lowest fuel consumption parking regeneration mode, the parking regeneration fuel consumption is the least.

[0097] S350, controlling the parking regeneration process of the vehicle according to the engine idle parameter.

[0098] In the embodiment, by obtaining the residual soot amount of the particulate filter, the required time and fuel consumption for completing the parking regeneration corresponding to each parking regeneration mode are determined according to the residual soot amount of the particulate filter and each parking regeneration mode, so that when responding to the parking regeneration request, the multiple parking regeneration modes are displayed, and the required time and fuel consumption for completing the parking regeneration corresponding to each parking regeneration mode are displayed, so that the user can select the parking regeneration mode meeting the user's own demand according to the user's own demand for the required time and fuel consumption for the parking regeneration and according to the required time and fuel consumption for completing the parking regeneration corresponding to each parking regeneration mode, and the controllability of the required time for the parking regeneration is further improved, so that the waiting time of the user can be further reduced, and the satisfaction of the user with the service is improved.
