Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The regeneration process of the vehicle engine can reduce the carbon accumulation in the DPF of the diesel particulate filter and reduce the pollution of the carbon emission to the environment. In which a DPF (Diesel Particulate filter) is installed in a ceramic filter in an aftertreatment system of a Diesel engine, which can adsorb soot particles in exhaust on a ceramic wall surface.
An Electronic Control Unit (ECU), also referred to as an engine controller, may autonomously Control whether to perform a regeneration process according to the carbon loading in the DPF of the diesel particulate filter, that is, the regeneration process may be performed at any time and in any environment. However, the regeneration process may cause some danger, for example, the regeneration process may generate heat, and when the vehicle is in the regeneration process, the temperature of the after-treatment tank is high, and a part of the after-treatment tank may reach 200 ℃, so that when the vehicle is located in some environment with temperature requirement, such as a gas station, etc., a certain degree of danger is caused to the surrounding environment.
In order to provide the driver with some human control capability, the vehicle may be provided with a regeneration prohibition switch, and in the case where the switch is turned on, the turning on of the regeneration process flow may be prohibited. However, after the regeneration process flow is prohibited, for example, the driver may forget to cancel the regeneration prohibition switch after turning on the regeneration prohibition switch, which may cause a safety hazard to the vehicle.
The present application provides a control flow of vehicle regeneration, which may specifically include steps S101 to S104, as shown in fig. 1.
S101: the regenerative state of the vehicle is obtained.
The regeneration state indicates whether or not the regeneration process flow is permitted, or can be understood as indicating whether or not the regeneration process flow is prohibited. Alternatively, it is understood that the regeneration state includes two, enabled or disabled.
The regenerative state of the vehicle may be determined by the control unit, for example, the control unit may prohibit the vehicle from entering the regeneration process flow in a case where the vehicle condition satisfies the prohibition condition, as determined by the vehicle condition. In this implementation, the regenerative state of the vehicle may be acquired from the control information of the control unit.
Alternatively, as described above, the vehicle may be provided with a regeneration prohibition switch that the driver may manually turn on to prohibit the vehicle from entering the regeneration process flow. In the case where the regeneration prohibition switch is canceled, the vehicle may be permitted to enter the regeneration process flow. In such an implementation, the state of the regeneration disable switch, which may be on or off, may be obtained. If the regeneration prohibition switch is on, the regeneration state can be determined as prohibition of entering the regeneration process; instead, the regeneration status may be determined as being allowed to enter the regeneration flow.
Or in one possible implementation, the regeneration disable switch may be replaced with a regeneration enable switch. The regeneration permission switch is implemented in the same manner as the regeneration prohibition switch, except that the regeneration permission switch is implemented in a different manner, and when the regeneration permission switch is turned on, execution of the regeneration processing flow is permitted, and when the regeneration permission switch is canceled, execution of the regeneration processing is prohibited. Also, a state of the regeneration allowing switch, which may be on or off, may be obtained, and the regeneration state of the vehicle may be determined based on the state of the regeneration allowing switch, similarly to the state of the regeneration prohibiting switch.
Whether the regenerative state of the vehicle is appropriate or not needs to be checked to see whether the regenerative state matches the external environment in which the vehicle is located. The next step is therefore to determine the ambient condition of the vehicle.
S102: determining the external environment type of the vehicle in the preset external environment types; the preset external environment type is an environment type divided according to whether the regeneration processing can be performed or not.
Before implementation, after the application scene is analyzed, two external environment types, namely a safe environment and a dangerous environment, are preset. The safe environment is also a dangerous environment, and the division is based on whether the external environment of the vehicle can carry out the regeneration treatment process.
Specifically, when the vehicle is subjected to a regeneration process, a high temperature may be generated at a local location, and if the external environment of the vehicle is a high temperature-prohibited environment such as a refueling station, the vehicle may bring a certain risk to the surrounding environment. It can be seen that in these external environments, the vehicle is not able to enter the regeneration process flow, and these environments can be marked as hazardous environments. Conversely, if the environment is not high temperature limited, the environment may be marked as a safe environment in which the vehicle can perform a regeneration process. From the above description, it can be considered that the dangerous environment is also a safe environment, and whether the environment has a limitation requirement for high temperature is classified.
The preset external environment types comprise the two types, in practical application, information such as the position of the vehicle can be obtained, and after the information such as the position of the vehicle is analyzed, the specific external environment type of the vehicle is determined.
Alternatively, the external environment may be divided into more kinds, not limited to the above two kinds. It is only necessary to set the regeneration status corresponding to different external environment types.
The first two steps are not limited to the illustrated order, and step S102 may be performed after step S101, or two steps may be performed simultaneously.
S103: and determining a target regeneration state corresponding to the external environment type.
Besides the preset external environment type, the regeneration state corresponding to the external environment type can be set. That is, in an external environment represented by an external environment type, the external environment requires whether the regeneration state is permitted or prohibited. In the permission state, the vehicle control unit may determine whether to enter the regeneration process flow according to the carbon load. In the prohibition state, the vehicle control unit cannot execute the above-described determination process, so that the vehicle does not autonomously enter the regeneration process flow.
According to the requirement of the external environment type on the high-temperature limitation, the regeneration state corresponding to each external environment type can be preset. According to the preset corresponding relation, the regeneration state corresponding to the external environment type of the vehicle can be determined, and for convenience of description, the regeneration state can be referred to as a target regeneration state.
S104: if the regeneration state of the vehicle does not coincide with the target regeneration state, the regeneration state of the vehicle is adjusted to the target regeneration state.
Here, step S101 may obtain a regeneration state of the vehicle, which is an actual regeneration state of the vehicle. Step S103 may determine the regeneration status required by the external environment of the vehicle according to the type of the external environment of the vehicle. And comparing the two regeneration states, and comparing whether the two regeneration states are consistent, wherein if the two regeneration states are consistent, the regeneration state of the vehicle is in accordance with the requirement of the external environment, and the vehicle does not need to be processed. If the two are not in agreement, the vehicle regeneration status needs to be adjusted to the target regeneration status determined in step S103.
According to the technical scheme, the vehicle regeneration control method can obtain the regeneration state of the vehicle, determine the external environment type of the vehicle, determine the target regeneration state corresponding to the external environment type, compare the regeneration state of the vehicle with the target regeneration state, and adjust the regeneration state of the vehicle to the target regeneration state if the regeneration state of the vehicle is not consistent with the target regeneration state. Therefore, the regeneration state of the vehicle can be adjusted according to the requirement of the external environment where the vehicle is located on the regeneration state of the vehicle, the automatic control of the regeneration state of the vehicle is achieved, the potential safety hazard caused by the vehicle to the external environment is avoided, and meanwhile the potential safety hazard caused by the vehicle to the vehicle in the regeneration forbidden state for a long time is also avoided.
Specifically, when the vehicle is in a dangerous environment such as a gas station or the like, the vehicle automatically enters a regeneration prohibition state, so that the potential safety hazard caused by the high temperature of the vehicle to the dangerous environment is avoided. Meanwhile, in a safe environment of the vehicle, the regeneration prohibition switch may be in a turned-on state, and the reason for the state may be that the driver forgets to reset after manually turning on the switch, or the driver operates illegally in order to reduce oil consumption, and the like.
In addition, the present application provides another method flow of vehicle regeneration control, which may specifically include steps S201 to S205, as shown in fig. 2.
S201: the regenerative state of the vehicle is determined based on the state of the regeneration prohibition switch.
In practical application, in order to prevent the regeneration prohibiting switch from being always in a closed state, the regeneration prohibiting switch is set to be a self-reset switch. One implementation of the regeneration-inhibiting switch is shown in fig. 3, the regeneration-inhibiting switch has an original state before being triggered by the click, and the original state of the switch is changed into the click-on-demand state after the click is triggered.
When a driver has a regeneration prohibition requirement, clicking a regeneration prohibition switch once, and determining that the regeneration prohibition switch is turned on after the control unit receives a switch rising edge signal; when the driver has a demand for canceling the regeneration prohibition, the driver clicks the regeneration prohibition switch once again, and the control unit determines that the regeneration prohibition switch is canceled after receiving the rising edge signal of the switch. Therefore, the state of the regeneration prohibition switch can be understood as reflecting the regeneration prohibition demand of the driver.
Based on the switch signal detected by the control unit, the state of the regeneration prohibition switch can be determined, thereby determining the regeneration state of the vehicle.
S202: and determining whether the vehicle is in a safe position or a dangerous position according to the position information sent by the positioning system.
The vehicle may be equipped with a positioning system such as a Global Positioning System (GPS), and the positioning system may provide real-time position information of the vehicle, and may determine the position of the vehicle at any time according to the real-time position information.
It is determined whether the position of the vehicle belongs to a safe position or a dangerous position. The safe position indicates a position where the vehicle can normally perform the regeneration process flow; the location of the hazard indicates that,
it should be noted that, in the technical solution of the present application, the safe position and the dangerous position are determined according to whether the vehicle is located within a dangerous area of a preset dangerous place. For example, it is determined whether the vehicle is located within a dangerous area of the gas station, and if so, the vehicle location is a dangerous location, and conversely, the vehicle location is a safe location.
As shown in fig. 4, a specific implementation manner is that after the real-time position of the vehicle is obtained, the distance between the real-time position and the set point, such as a gas station, closest to the built-in map of the vehicle is obtained by comparing the real-time position and the set point. And the distance between the vehicle communication bus and the dangerous position is sent to the vehicle communication bus through a message, the control unit compares the information of the communication bus with the preset calibrated safety distance, if the information is less than the safety distance, a signal corresponding to the dangerous position is output, and if the information is more than or equal to the safety distance, a signal corresponding to the safety position is output.
S203: and determining the running state of the vehicle according to the vehicle speed information sent by the instrument panel.
According to the technical scheme, the driving states of the vehicle comprise three states, namely a static state, a low-speed driving state and a high-speed driving state. The instrument panel can record and display the vehicle speed information of the vehicle, and determine the specific running state of the vehicle according to the vehicle speed information.
Although the vehicle position obtained in step S202 may indicate whether the vehicle is in a safe position or a dangerous position, the position of the vehicle at a certain time point may not accurately indicate the external environment condition of the vehicle during the driving process of the vehicle, and therefore, it is necessary to perform comprehensive judgment in combination with the driving state of the vehicle.
As shown in fig. 5, after obtaining the vehicle speed from the instrument panel, comparing the vehicle speed with a set speed value, and if the vehicle speed obtained from the instrument panel is greater than or equal to the set speed value, determining that the vehicle is in a high-speed driving state; if the vehicle speed obtained from the instrument panel is less than the set speed value and greater than 0, determining that the vehicle is in a low-speed running state; if the vehicle speed obtained from the instrument panel is equal to 0, the vehicle is determined to be in a stationary state.
S204: whether the regeneration state of the vehicle needs to be adjusted is determined according to the running state of the vehicle and whether the vehicle is in a safe position or a dangerous position.
Specifically, the external environment type of the vehicle is determined according to the running state of the vehicle and whether the vehicle is in a safe position or a dangerous position, the target regeneration state corresponding to the external environment type is determined, the regeneration state of the vehicle is compared with the target regeneration state, and whether the regeneration state of the vehicle needs to be adjusted or not is determined according to the fact that whether the regeneration state of the vehicle is consistent with the target regeneration state or not.
In specific implementation, the driving state of the vehicle can be firstly judged, and if the driving state is the static state, the external environment type of the vehicle can be directly determined according to whether the vehicle is in a safe position or a dangerous position. That is, if the vehicle speed information indicates that the vehicle is in a stationary state, the external environment type corresponding to the position information is determined as the external environment type in which the vehicle is located.
If the vehicle is stationary and in a vehicle safe location, it may be determined that the type of external environment in which the vehicle is located is a safe environment type. The target regeneration state corresponding to the safe environment type is a regeneration-allowed state, and if the regeneration state of the vehicle does not coincide therewith, it may be determined that the regeneration state of the vehicle needs to be adjusted.
If the vehicle is in a stationary state and in a dangerous position of the vehicle, it can be determined that the type of the external environment in which the vehicle is located is a dangerous environment type. The target regeneration state corresponding to the hazardous environment type is a regeneration prohibition state, and if the regeneration state of the vehicle does not match the target regeneration state, it can be determined that the regeneration state of the vehicle needs to be adjusted.
If the driving state of the vehicle is a low-speed driving state and the vehicle is in a dangerous position, it may be determined that the external environment type in which the vehicle is located is a dangerous environment type. The target regeneration state corresponding to the hazardous environment type is a regeneration prohibition state, and if the regeneration state of the vehicle does not match the target regeneration state, it can be determined that the regeneration state of the vehicle needs to be adjusted.
If the running state of the vehicle is a low-speed running state, and the vehicle is in a safe position, and the regeneration state of the vehicle is a regeneration-prohibited state, there may be some special cases where the following detailed judgment is required in consideration of the existence of these special cases.
In a special case, while the vehicle is running, although the running position is a safety position set by the system, the driver may judge that the regeneration treatment is not allowed on the road according to the surrounding road conditions, for example, inflammable substances such as wheat straws exist on the road, and then the driver may turn on the regeneration prohibition switch, so that the regeneration state of the vehicle is the regeneration prohibition state. However, after the driver turns on the switch and drives out the road, the driver forgets to cancel the switch, and the vehicle cannot normally perform the regeneration treatment.
In this case, the present application assumes that the dangerous state of the road disappears after the vehicle travels a distance, so, in this case (i.e., the traveling state of the vehicle is a low-speed traveling state, the vehicle is in a safe position, and the regeneration state of the vehicle is a regeneration-prohibited state), after the vehicle travels a preset distance from the regeneration-prohibited state, the external environment type of the vehicle is determined again, and the external environment type of the vehicle at this time is determined as a safe environment type. The target regeneration state corresponding to the safe environment type is a regeneration-allowed state, and if the regeneration state of the vehicle does not coincide therewith, it may be determined that the regeneration state of the vehicle needs to be adjusted.
The above-described special case may also occur if the vehicle running state is a high-speed running state, and therefore it is also necessary to determine the external environment type of the vehicle after the vehicle has traveled a preset distance from the regeneration prohibition state, and determine the external environment type of the vehicle at this time as the safe environment type. The target regeneration state corresponding to the safe environment type is a regeneration-allowed state, and if the regeneration state of the vehicle does not coincide therewith, it may be determined that the regeneration state of the vehicle needs to be adjusted. It should be noted that, in the high-speed driving state, it is not necessary to determine the position of the vehicle, because the vehicle driving at high speed does not cause serious potential safety hazard to a fixed dangerous place.
Thus, in the special application scenario, if the driver forgets to cancel the regeneration prohibition switch, the regeneration state of the vehicle can be forced to be adjusted to the regeneration permission state, so as to ensure the normal execution of the regeneration processing flow of the vehicle.
In the above-described special application scenario, in order to confirm whether the driver has forgotten to cancel the regeneration prohibition switch, the regeneration state of the vehicle is determined again after the vehicle travels the preset distance, and the regeneration state is compared with the target regeneration state.
S205: if the regenerative state of the vehicle needs to be adjusted, the regenerative state of the vehicle is adjusted.
Among them, one way to adjust the regenerative state of the vehicle is to adjust the state of the regeneration prohibition switch, or another way is to directly set the regenerative state of the vehicle by the control unit.
According to the technical scheme, the vehicle regeneration control method can achieve distance measurement between a vehicle and a set place which is not suitable for regeneration, meanwhile, the driving state of the vehicle and the state required by a regeneration prohibition switch of a driver are identified, independent judgment of the regeneration prohibition requirement of the vehicle in static state, low speed and high speed can be achieved respectively, the situation that the danger coefficient of the vehicle is increased due to the fact that the vehicle regenerates in an area which is not suitable for regeneration because the driver forgets to press the regeneration prohibition switch is effectively avoided, and the situation that a vehicle is blocked due to too much carbon deposition in a vehicle after-treatment box due to the fact that the driver presses the regeneration prohibition switch for a long time is also avoided.
