Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The control method of the vehicle particulate filter can be applied to the application environment shown in FIG. 1. Where the vehicle 110 communicates with the service platform 120 over a network. First, the vehicle 110 acquires vehicle identification information. Then, the vehicle 110 sends the vehicle identification information to the service platform; the vehicle identification information is used for the service platform to determine a regeneration control scheme corresponding to the particulate filter of the vehicle; finally, the vehicle 110 receives the service platform's regeneration control scheme and performs regeneration control of the vehicle's particulate filter according to the regeneration control scheme. The service platform 120 may be implemented by a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, there is provided a control method of a particulate filter for a vehicle, including the steps of:
and S210, acquiring vehicle identification information.
The vehicle identification information may refer to unique identification information for characterizing the identity of the current vehicle. Such as license plate information, vehicle identification number, engine number, and the like.
In practical applications, the vehicle identification information may be identification information corresponding to an on-board automatic diagnostic system (OBD) installed in the vehicle 110.
In specific implementation, the on-board automatic diagnosis system of the vehicle 110 obtains identification information of the system to obtain OBD identification information, and then uses the OBD identification information as vehicle identification information corresponding to the vehicle 110.
S220, sending the vehicle identification information to the service platform 120; the vehicle identification information is used by the service platform 120 to determine a regeneration control scheme corresponding to the particulate filter of the vehicle.
The regeneration control scheme may refer to a scheme for controlling a particulate filter in the vehicle 110 to be regenerated.
In a specific implementation, after the vehicle-mounted automatic diagnosis system of the vehicle 110 obtains the vehicle identification information of the vehicle 110, the vehicle-mounted automatic diagnosis system of the vehicle 110 generates a regeneration scheme obtaining request, and sends the regeneration scheme obtaining request to the service platform 120 for the service platform 120 to receive. Wherein the regeneration scheme acquisition request carries vehicle identification information.
When the service platform 120 receives the request for obtaining the regeneration scheme of the vehicle 110, the service platform 120 determines the vehicle identification information carried by the request for obtaining the regeneration scheme. Then, the service platform 120 queries a database for a regeneration control scheme corresponding to the particulate filter used by the vehicle 110 by using the vehicle identification information. More specifically, the service platform 120 determines a brand of particulate filter currently used by the vehicle 110 in the database through the vehicle identification information, and then the service platform 120 determines a regeneration control scheme corresponding to the brand of particulate filter used by the vehicle 110 according to the brand of particulate filter. Finally, service platform 120 sends the regeneration control scheme to vehicle 110 for receipt by an on-board automatic diagnostic system of vehicle 110.
It should be noted that, the staff needs to enter in advance vehicle identification information corresponding to each vehicle, a model corresponding to each vehicle, a DPF brand and manufacturer equipped for each vehicle, and regeneration configuration information corresponding to each particulate filter brand or manufacturer in the service platform 120, so that the service platform 120 determines a regeneration control scheme corresponding to the particulate filter of the vehicle 110 according to the vehicle identification information of the vehicle 110.
To facilitate understanding by those skilled in the art, in one embodiment, referring to table 1, a table of regeneration configuration information for a control method of a particulate filter of a vehicle is provided;
table 1 the regeneration configuration information table S230 receives the regeneration control scheme transmitted from the service platform, and controls the particulate filter of the vehicle to regenerate according to the regeneration control scheme.
In a specific implementation, after the on-board automatic diagnostic system of the vehicle 110 receives the regeneration control scheme sent by the service platform 120, the on-board automatic diagnostic system of the vehicle 110 generates the regeneration control command according to the regeneration control scheme and in combination with the temperature of the particulate filter of the vehicle 110. The regeneration control command comprises an active regeneration command and a temperature regulation command. The on-board automatic diagnostic system of vehicle 110 may then control the particulate filter of vehicle 110 to regenerate by sending an active regeneration command and a temperature adjustment command to the particulate filter of vehicle 110.
In the control method of the vehicle particulate filter, the service platform determines a regeneration control scheme corresponding to the particulate filter of the vehicle by acquiring the vehicle identification information and sending the vehicle identification information to the service platform; then, the regeneration of the particulate filter of the vehicle is controlled according to the regeneration control scheme by receiving the regeneration control scheme of the service platform; therefore, the particle filter of the vehicle can be reasonably regenerated and controlled in a targeted manner, and the regeneration effect and efficiency of the particle filter of the vehicle are improved.
In another embodiment, the method further comprises: acquiring a vehicle fault code of a vehicle; judging whether the particle filter needs to be regenerated or not according to the vehicle fault code; if so, a step of performing regeneration control of the particulate filter of the vehicle according to a regeneration control scheme is performed.
The vehicle fault code may be a fault code reflected by analysis of an automobile computer ecu (electronic control unit) after the vehicle has a fault.
In particular implementations, when a particulate filter of vehicle 110 is clogged, vehicle 110 may generate a vehicle fault code for the clogging of the particulate filter. The vehicle-mounted automatic diagnosis system of the vehicle 110 acquires a current vehicle fault code of the vehicle 110; and determines whether the particulate filter of the vehicle 110 needs to be regenerated at that time, based on the vehicle trouble code of the vehicle 110. If it is determined that the fault type corresponding to the vehicle fault code is the particulate filter clogging, the vehicle 110 executes a step of performing regeneration control on the particulate filter of the vehicle according to a regeneration control scheme. Specifically, an on-board automatic diagnostic system of vehicle 110 may generate a regeneration control command based on the regeneration control scheme in conjunction with the temperature of the particulate filter of vehicle 110. The regeneration control command comprises an active regeneration command and a temperature regulation command. The on-board automatic diagnostic system of vehicle 110 may then control the particulate filter of vehicle 110 to regenerate by sending an active regeneration command and a temperature adjustment command to the particulate filter of vehicle 110.
According to the technical scheme, the vehicle fault code of the vehicle is obtained, so that whether the particle filter used by the vehicle needs to be regenerated or not can be accurately judged according to the vehicle fault code, the particle filter can be regenerated in time, and the effect and the efficiency of the vehicle on the regeneration of the particle filter are improved.
In another embodiment, controlling a particulate filter of a vehicle to regenerate according to a regeneration control scheme includes: obtaining a current temperature of the particulate filter; generating a regeneration control signal for the particulate filter based on the current temperature and the regeneration control scheme; the regeneration control signal is used to regenerate the particulate filter.
The regeneration control signal may be a signal for controlling the particulate filter to regenerate.
In a specific implementation, the on-board automatic diagnostic system of the vehicle 110, in the process of controlling the particulate filter of the vehicle to regenerate according to the regeneration control scheme, specifically includes: an on-board automatic diagnostic system of vehicle 110 obtains a current temperature of a particulate filter of vehicle 110. Then, the on-board automatic diagnostic system of vehicle 110 generates a regeneration control signal for the particulate filter by combining the current temperature and the regeneration control scheme; finally, the on-board automatic diagnostic system of vehicle 110 sends the regeneration control signal to the particulate filter of vehicle 110 to regenerate the particulate filter. Wherein the regeneration control signal comprises an active regeneration control signal and a temperature regulation control signal. The active regeneration control signal is used to control the particulate filter to perform active regeneration.
According to the technical scheme of the embodiment, the vehicle generates the corresponding regeneration control signal according to the current temperature of the particulate filter and the regeneration control scheme, so that the particulate filter of the vehicle is subjected to reasonable regeneration control in a targeted manner, and the regeneration effect and efficiency of the particulate filter of the vehicle are improved.
In another embodiment, generating a regeneration control signal for a particulate filter based on a current temperature and a regeneration control scheme includes: determining a passive regeneration temperature range for the particulate filter based on the regeneration control scheme; judging whether the current temperature meets the passive regeneration temperature range; if so, determining an active regeneration temperature and an active regeneration duration for the particulate filter according to a regeneration control scheme; generating an active regeneration control signal according to the active regeneration temperature and the active regeneration duration; the active regeneration control signal is used to cause the particulate filter to actively regenerate according to an active regeneration temperature and an active regeneration time period.
In a specific implementation, the on-board automatic diagnostic system of the vehicle 110, in generating the regeneration control signal for the particulate filter according to the current temperature and the regeneration control scheme, specifically includes: the on-board automatic diagnostic system of vehicle 110 determines a passive regeneration temperature range for the particulate filter according to a regeneration control scheme; then, the on-board automatic diagnostic system of vehicle 110 determines whether the current temperature of the particulate filter satisfies the passive regeneration temperature range; if the current temperature of the particulate filter meets the passive regeneration temperature range, determining an active regeneration temperature and an active regeneration duration for the particulate filter according to a regeneration control scheme; then, the on-board automatic diagnostic system of the vehicle 110 generates an active regeneration control signal based on the active regeneration temperature and the active regeneration time period to cause the particulate filter to actively regenerate according to the active regeneration temperature and the active regeneration time period.
For example, when the on-board automatic diagnostic system of the vehicle 110 controls the particulate filter to perform active regeneration according to the active regeneration temperature and the active regeneration duration, the on-board automatic diagnostic system of the vehicle 110 generates an active regeneration control signal, and further may adjust the injection pulse width of the injection pump to control the injection amount of the injection pump and/or start the electrical heating, microwave heating, infrared heating, and the like of the particulate filter, so that the temperature of the particulate filter reaches the active regeneration temperature, that is, reaches the ignition point of the particulate matter in the particulate filter, and maintains the active regeneration duration, for example, 200 seconds to 300 seconds, and then ends the active regeneration process of the particulate filter.
According to the technical scheme of the embodiment, the vehicle determines the passive regeneration temperature range of the particulate filter through a regeneration control scheme; when the current temperature of the particulate filter is determined to meet the passive regeneration temperature range, the vehicle determines an active regeneration temperature and an active regeneration duration for the particulate filter according to a regeneration control scheme; generating an active regeneration control signal according to the active regeneration temperature and the active regeneration time length, so as to control the particulate filter to perform active regeneration according to the active regeneration temperature and the active regeneration time length; therefore, reasonable regeneration control of the particulate filter of the vehicle is realized, and the regeneration effect and efficiency of the particulate filter of the vehicle are improved.
In another embodiment, the method further comprises: generating a temperature adjustment control signal for the particulate filter when the current temperature does not satisfy the passive regeneration temperature range; the temperature adjustment control signal is used for enabling the current temperature of the particulate filter to meet the passive regeneration temperature range; and returning to the step of judging whether the current temperature meets the passive regeneration temperature range.
In a specific implementation, when the on-board automatic diagnostic system of vehicle 110 detects that the current temperature of the particulate filter does not satisfy the passive regeneration temperature range, the on-board automatic diagnostic system of vehicle 110 generates a temperature adjustment control signal for the particulate filter, and the temperature adjustment control signal controls the current temperature of the particulate filter to satisfy the passive regeneration temperature range, and returns to the step of determining whether the current temperature satisfies the passive regeneration temperature range.
For example, when the current temperature of the particulate filter is lower than the lowest temperature value of the passive regeneration temperature range, at this time, the temperature adjustment control signal generated by the vehicle-mounted automatic diagnostic system of the vehicle 110 is used to increase the fuel injection amount of the fuel injection pump or start the electrical heating, microwave heating, infrared heating, and the like of the particulate filter, so as to increase the temperature of the particulate filter until the current temperature of the particulate filter satisfies the passive regeneration temperature range, and the step of determining whether the current temperature satisfies the passive regeneration temperature range is returned.
When the current temperature of the particulate filter is higher than the maximum temperature value of the passive regeneration temperature range, at this time, the temperature adjustment control signal generated by the vehicle-mounted automatic diagnostic system of the vehicle 110 is used to control the modes of reducing the fuel injection quantity of the fuel injection pump or stopping the electrical heating, the microwave heating, the infrared heating and the like of the particulate filter, so as to reduce the temperature of the particulate filter until the current temperature of the particulate filter meets the passive regeneration temperature range, and the step of judging whether the current temperature meets the passive regeneration temperature range is returned.
According to the technical scheme of the embodiment, when the current temperature of the particulate filter does not meet the passive regeneration temperature range, the vehicle adjusts the control signal according to the temperature of the particulate filter so that the current temperature of the particulate filter meets the passive regeneration temperature range, then active regeneration is carried out, reasonable regeneration control of the particulate filter of the vehicle is achieved, and therefore the regeneration effect and efficiency of the particulate filter of the vehicle are improved.
In another embodiment, after the step of regenerating the particulate filter, the method further comprises: obtaining a current pressure differential of the particulate filter, and determining a normal pressure differential of the particulate filter according to a regeneration control scheme; judging whether the current pressure difference is smaller than the normal pressure difference; if so, the particulate filter is judged to be recovered to be normal.
The differential pressure may be a pressure difference between an upstream exhaust pipe and a downstream exhaust pipe of the vehicle.
The normal pressure difference may refer to a pressure difference in which a particulate filter of a vehicle is in a normal state.
In a particular implementation, an on-board automatic diagnostic system of vehicle 110 obtains a current differential pressure of the particulate filter after the step of generating the active regeneration control signal based on the active regeneration temperature and the active regeneration duration. Meanwhile, the on-board automatic diagnostic system of the vehicle 110 determines a pressure difference when the particulate filter used by the vehicle 110 is in a normal state, that is, a normal pressure difference, in the regeneration control scheme. Then, the vehicle-mounted automatic diagnostic system of the vehicle 110 determines whether the current differential pressure is smaller than the normal differential pressure; if so, the particulate filter is judged to be recovered to be normal.
In addition, when it is determined that the particulate filter has returned to normal, the on-board automatic diagnostic system of the vehicle 110 may also generate a regeneration success message for the particulate filter, by which the user is reminded that the particulate filter of the vehicle 110 has returned to normal at this time.
According to the technical scheme of the embodiment, after the vehicle generates the active regeneration control signal according to the active regeneration temperature and the active regeneration duration, whether the current pressure difference is smaller than the normal pressure difference is judged, so that whether the particle filter subjected to the active regeneration is recovered to be normal is accurately judged, the control signal is timely adjusted, accordingly, the particle filter of the vehicle is pertinently and reasonably subjected to regeneration control, and the regeneration effect of the particle filter of the vehicle is improved.
In another embodiment, the method further comprises: when the current pressure difference is larger than the normal pressure difference, acquiring the regenerated times of the particulate filter, and determining the regenerated times of the particulate filter according to a regeneration control scheme; judging whether the regenerated times exceed the regenerated times; if not, updating the regeneration times of the particulate filter, and returning to the step of judging whether the current temperature meets the passive regeneration temperature range; if yes, generating an abnormal alarm aiming at the particle filter; the anomaly alert is used to alert a user to service the particulate filter.
The number of regenerations may be the number of times the particulate filter has completed regeneration.
The number of regenerations may be the number of times the particulate filter can be regenerated.
In a specific implementation, when the on-board automatic diagnostic system of vehicle 110 still detects that the current differential pressure of the particulate filter is greater than the normal differential pressure after the particulate filter completes one active regeneration, the on-board automatic diagnostic system of vehicle 110 obtains the number of times that the particulate filter has been regenerated, and determines the number of times that the particulate filter can be regenerated in the regeneration control scheme. Then, the on-board automatic diagnostic system of vehicle 110 determines whether the number of regenerations exceeds the number of regenerations; if not, the vehicle-mounted automatic diagnosis system of the vehicle 110 updates the regeneration times of the particulate filter, returns to the step of judging whether the current temperature meets the passive regeneration temperature range, and regenerates the particulate filter again; if so, it is indicated that the current particulate filter may be damaged, so the vehicle-mounted automatic diagnostic system of the vehicle 110 stops regenerating the particulate filter to save energy, generates and reports an abnormality alarm for the particulate filter, and further reminds the user of needing to repair the particulate filter through the abnormality alarm.
According to the technical scheme of the embodiment, when the particle filter completes one-time active regeneration and the current pressure difference is still larger than the normal pressure difference, the regeneration times of the particle filter are updated by judging whether the regeneration times exceed the regeneration times or not, and the step of judging whether the current temperature meets the passive regeneration temperature range or not is returned; if so, generating an abnormal alarm aiming at the particle filter and stopping regenerating the particle filter so as to save energy; the reasonable regeneration control of the particulate filter of the vehicle is realized, and the regeneration effect of the particulate filter of the vehicle is improved.

S390, judging whether the regenerated times exceed the renewable times; if not, updating the regenerated times of the particulate filter, and returning to the step of judging whether the current temperature meets the passive regeneration temperature range. By adopting the control method of the vehicle particle filter, the reasonable regeneration control can be carried out on the vehicle particle filter in a targeted manner, and the regeneration effect of the vehicle particle filter is improved.

To facilitate understanding by those skilled in the art, as shown in fig. 4, a control flow diagram of a control method of a particulate filter of a vehicle is provided; the OBD of the vehicle acquires a vehicle fault code, and when the DPF regeneration is determined to be needed according to the vehicle fault code, the regeneration period number is 1. Then, checking whether the current DPF temperature accords with a passive regeneration temperature range; if not, the temperature of the DPF is adjusted by adjusting the oil injection quantity of the oil injection pump or starting/stopping the electric heating, microwave heating and infrared heating functions of the particulate filter. And if the current DPF temperature accords with the passive regeneration temperature range, controlling the DPF temperature, and performing active regeneration according to the active regeneration temperature and the active regeneration time length in the regeneration control scheme. When the active regeneration is finished, checking whether the pressure difference of the DPF is smaller than a preset normal pressure difference; if yes, the DPF regeneration is judged to be finished.
