Description

Vehicle regeneration control method and device

Technical field

The present application relates to the field of vehicle technology, and more particularly to a vehicle regeneration control method and apparatus.

Background technique

Vehicles need to be powered by diesel and other energy sources. The energy combustion process produces emissions containing carbon particles, which can pollute the environment. In order to achieve energy saving and environmental protection, some vehicles currently perform regeneration processing operations on the engine according to the amount of carbon accumulation.

Regeneration means that when the carbon load in the DPF (DPF-Diesel Particulate Filer) accumulates to a certain value, the injection unit injects diesel into the exhaust line, and uses the oxidation reaction of diesel to release heat. The temperature inside the DPF causes the carbon particles in the DPF to undergo high-temperature oxidation reaction to produce CO and CO2, thereby reducing the carbon load. It can be seen that the regeneration process can reduce the carbon load of the DPF.

Detailed ways

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. 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 obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

The regeneration process of the vehicle engine can reduce the carbon accumulation in the diesel particulate trap DPF and reduce the environmental pollution caused by carbon emissions. Among them, DPF (DPF-Diesel Particulate Filer) is a ceramic filter installed in a diesel engine after-treatment system, which can adsorb soot particles in the exhaust on the ceramic wall.

The Electronic Control Unit (ECU), also known as the engine controller, can autonomously control whether or not to perform regeneration processing according to the carbon load in the diesel particulate trap DPF. That is, the regeneration process may be in any When any environment is in progress. However, the regeneration process may have certain risks. For example, the regeneration process can generate heat. When the vehicle is in the process of regeneration, the temperature of the post-treatment tank is high, and some positions can reach 200 ° C. Therefore, when the vehicle is located in some environment where temperature is required. If it is a gas station, it will cause a certain degree of danger to the surrounding environment.

In order to provide the driver with some artificial control capability, a regeneration prohibition switch can be set on the vehicle, and in the case where the switch is turned on, the regeneration processing flow can be prohibited from being turned on. However, after the regeneration process 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. As shown in FIG. 1 , the flow may specifically include steps S101 to S104.

S101: Obtain a regeneration state of the vehicle.

Here, the reproduction state indicates a state in which the regeneration processing flow is permitted, or can be understood as a state indicating whether or not the regeneration processing flow is prohibited. Or it can be understood that the regeneration state includes two types, permission or prohibition.

The regeneration state of the vehicle may be determined by the control unit. For example, the control unit determines based on the vehicle condition, and may prohibit the vehicle from entering the regeneration processing flow if the vehicle condition satisfies the prohibition condition. In this implementation, the regeneration state of the vehicle can be obtained from the control information of the control unit.

Or as above, the vehicle can be provided with a regeneration prohibition switch, and the driver can manually turn on the switch to prohibit the vehicle from entering the regeneration process. In the case where the regeneration prohibition switch is canceled, the vehicle can be allowed to enter the regeneration processing flow. In this implementation, the state of the regeneration inhibit switch can be obtained, which may be either on or off. If the state of the regeneration inhibit switch is on, it can be determined that the regeneration state is prohibited from entering the regeneration process; on the contrary, it can be determined that the regeneration state is allowed to enter the regeneration process.

Or in one possible implementation, the regeneration inhibit switch can be replaced with a regeneration enable switch. The function of the regeneration enable switch is the same as that of the regeneration prohibition switch. However, the implementation of the two is different. When the regeneration enable switch is turned on, the execution of the regeneration process is allowed, and the regeneration permission switch is cancelled. Next, it is implemented that the execution of the regeneration processing is prohibited. Similarly, the state of the regeneration permission switch can be obtained, which may be either on or off, similar to the regeneration prohibition switch state, and the regeneration state of the vehicle can be determined according to the state of the regeneration permission switch.

Whether the regeneration state of the vehicle is appropriate depends on whether the regeneration state matches the external environment in which the vehicle is located. Therefore, the next step is to determine the external environmental conditions of the vehicle.

S102: Determine, in a preset external environment type, an external environment type in which the vehicle is located; wherein the preset external environment type is an environment type classified according to whether the regeneration process can be performed.

Before the implementation, the application analyzes the application scenarios and presets two types of external environments, namely a security environment and a dangerous environment. The safe environment is also a dangerous environment, based on whether the external environment in which the vehicle is located can be recycled.

Specifically, when the vehicle performs the regeneration process, the local location will generate high temperature. If the external environment of the vehicle is a high temperature prohibiting environment, such as a fueling station, the vehicle will bring certain danger to the surrounding environment. It can be seen that in these external environments, vehicles are not able to enter the recycling process and can mark these environments as hazardous environments. Conversely, if the external environment does not have a high temperature limit, the external environment can be marked as a safe environment, and the vehicle can perform a regeneration process in a safe environment. According to the above description, it can be considered that the hazardous environment is also a safe environment, and the basis is based on whether there is a restriction on the high temperature.

The preset external environment types include the above two types. In actual applications, information such as the position of the vehicle can be obtained, and after analyzing the information such as the position of the vehicle, it is determined which type of external environment the vehicle is in.

Alternatively, the external environment can be divided into more types, not limited to the above two. As long as the corresponding regeneration state is set for different external environment types.

It should be noted that the first two steps are not limited to the illustrated order, and may be performed in step S102 before the previous step S101, or may be performed simultaneously in two steps.

S103: Determine a target regeneration state corresponding to the external environment type.

In addition to setting the external environment type in advance, it is also possible to set the regeneration state corresponding to the external environment type. That is to say, in an external environment represented by an external environment type, the external environment requires the regeneration state to be permitted or prohibited. In the allowable state, the vehicle control unit can judge whether or not to enter the regeneration process according to the carbon load. In the prohibited state, the vehicle control unit cannot perform the above-described judging process, so that the vehicle does not enter the regenerative processing flow autonomously.

According to the requirements of the external environment type for the high temperature limit, the regeneration state corresponding to each external environment type can be set in advance. According to the preset correspondence relationship, the regeneration state corresponding to the type of the external environment in which the vehicle is located can be determined. For convenience of description, the regeneration state can be referred to as the 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.

Wherein, in step S101, the regeneration state of the vehicle can be obtained, and the regeneration state is the actual regeneration state of the vehicle. Step S103 can determine the regeneration state required by the external environment in which the vehicle is located according to the type of external environment in which the vehicle is located. The two regeneration states are compared to compare whether the two are consistent. If they are consistent, it indicates that the regeneration state of the vehicle is in compliance with external environmental requirements and does not have to be processed. If the two do not match, it is necessary to adjust the vehicle regeneration state and adjust it to the target regeneration state determined in step S103.

It can be seen from the above technical solution that the present application provides a vehicle regeneration control method, which can obtain a regeneration state of a vehicle, determine an external environment type in which the vehicle is located, and determine a target regeneration state corresponding to the external environment type, and the vehicle The regeneration state is compared with the target regeneration state, and if not, the regeneration state of the vehicle is adjusted to the target regeneration state. It can be seen that the present application can adjust the regeneration state of the vehicle according to the requirements of the environment in which the vehicle is located, and realize the automatic control of the vehicle regeneration state, thereby avoiding the safety hazard caused by the vehicle to the external environment and avoiding the safety hazard caused by the vehicle to the external environment. The vehicle poses a safety hazard to the vehicle itself in the long-term prohibition of regeneration.

Specifically, when the vehicle is in a dangerous environment such as a gas station or the like, it automatically enters a regeneration prohibition state, thereby avoiding a safety hazard caused by the high temperature of the vehicle to the dangerous environment. At the same time, the vehicle in a safe environment, the regeneration prohibition switch may be in the opened state, the reason for this state may be that the driver forgets to reset after manually turning on the switch, or the driver in order to reduce the fuel consumption violation operation, etc., in this case Under the above, the vehicle can be forced into the regeneration permission state, thereby preventing the vehicle from entering the regeneration process for a long period of time, resulting in excessive carbon deposition in the aftertreatment box and blocking, thereby ensuring the safety of the vehicle.

In addition, the present application provides another method flow of vehicle regeneration control. As shown in FIG. 2, the method flow may specifically include steps S201-S205.

S201: Determine a regeneration state of the vehicle according to a state of the regeneration prohibition switch.

Among them, in practical applications, in order to prevent the regeneration prohibition switch from being always in the closed state, the regeneration prohibition switch is set to the self-reset switch. One implementation of the regeneration inhibit switch is shown in FIG. 3. The regeneration prohibition switch has an original state before being tapped, and after the trigger is clicked, the original state of the switch is changed to the demand state.

When the driver has a request for regeneration prohibition, press the regeneration prohibition switch once. After receiving the switch rising edge signal, the control unit determines that the regeneration prohibition switch is turned on. When the driver cancels the regeneration prohibition request, press the regeneration prohibition switch again to control. After the unit receives the rising edge of the switch, it determines that the regeneration inhibit switch is canceled. Therefore, the state of the regeneration prohibition switch can be understood as reflecting the driver's regeneration prohibition demand.

Based on the switching signal detected by the control unit, the state of the regeneration inhibiting switch can be determined to determine the regeneration state of the vehicle.

S202: Determine whether the vehicle is in a safe position or a dangerous position according to the location information sent by the positioning system.

The vehicle can be loaded with a positioning system such as a Global Positioning System (GPS), and the positioning system can provide real-time position information of the vehicle, and according to the real-time position information, the position of the vehicle at any moment can be determined.

Determine if the location of the vehicle is a safe or dangerous location. The safe position indicates the position at which the vehicle can normally perform the regeneration process; the dangerous position 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 in a dangerous area of the preset dangerous place. For example, the preset gas station is a dangerous place, and it is judged whether the position of the vehicle is within the dangerous area of the gas station, and if so, the indicated vehicle position is a dangerous position, and the opposite is a safe position.

As shown in FIG. 4, a specific implementation manner is: after obtaining the real-time position of the vehicle, comparing with the set location closest to the built-in map of the vehicle, such as a gas station, to obtain the distance between the two. The distance between the two is sent to the vehicle communication bus through the message, and after receiving the information of the communication bus, the control unit compares with the pre-calibrated safety distance, and if it is less than the safety distance, outputs a signal corresponding to the dangerous position, if it is greater than or equal to safety The distance outputs a signal corresponding to the safe position.

S203: Determine a running state of the vehicle according to the vehicle speed information sent by the dashboard.

Among them, in the technical solution of the present application, the running state of the vehicle includes three types, which are a stationary state, a low speed running state, and a high speed running state. The dashboard can record and display the vehicle speed information of the vehicle, and based on the vehicle speed information, determine which one of the vehicle's driving state is specific.

Although the vehicle position obtained in step S202 may indicate whether the vehicle is in a safe position or a dangerous position, but the vehicle may be in the process of running, the position of the vehicle at a certain point in time does not accurately indicate the external environmental condition of the vehicle, and therefore needs to be combined. The driving state of the vehicle is comprehensively judged.

A way of judging the driving state is as shown in FIG. 5. After obtaining the vehicle speed from the instrument panel, the vehicle speed is compared with the set speed value. If the vehicle speed obtained from the instrument panel is greater than or equal to the set speed value, it is determined that the vehicle is in the vehicle. The high speed driving state; if the vehicle speed obtained from the instrument panel is less than the set speed value and greater than 0, it is determined that the vehicle is in the low speed running state; if the vehicle speed obtained from the instrument panel is equal to 0, it is determined that the vehicle is in the stationary state.

S204: Determine whether the regeneration state of the vehicle needs to be adjusted according to the running state of the vehicle and whether the vehicle is in a safe position or a dangerous position.

Specifically, according to the driving state of the vehicle and whether the vehicle is in a safe position or a dangerous position, the type of the external environment in which the vehicle is located is determined, the target regeneration state corresponding to the external environment type is determined, and the regeneration state of the vehicle is compared with the target regeneration state, according to Whether the two are consistent to determine whether the vehicle's regeneration status needs to be adjusted.

In a specific implementation, it may be first determined which type of driving state the vehicle is, and if it is in a stationary state, the external environment type of the vehicle may be determined directly according to whether the vehicle is in a safe position or a dangerous position. That is to say, if the vehicle speed information indicates that the vehicle is in a stationary state, the type of the external environment corresponding to the location information is determined as the type of the external environment in which the vehicle is located.

If the vehicle is at a standstill and in a safe position in the vehicle, it can 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 safety environment type is the allowable regeneration state, and if the regeneration state of the vehicle does not coincide with this, it can be determined that the regeneration state of the vehicle needs to be adjusted.

If the vehicle is at a standstill and in a dangerous position of the vehicle, it can be determined that the type of external environment in which the vehicle is located is a hazardous environment type. The target regeneration state corresponding to the hazardous environment type is the prohibition regeneration state, and if the vehicle regeneration state does not coincide with this, it can be determined that the vehicle regeneration state 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 can 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 the prohibition regeneration state, and if the vehicle regeneration state does not coincide with this, it can be determined that the vehicle regeneration state needs to be adjusted.

If the driving state of the vehicle is a low-speed driving state, and the vehicle is in a safe position, and the regenerative state of the vehicle is a prohibited regeneration state, there may be some special cases at this time, and in consideration of the existence of these special circumstances, the following detailed judgment is required.

A special case is that, while the vehicle is in the process of driving, although the position that has been driven is the safe position set by the system, the driver may judge the section of the road according to the surrounding road conditions and is not allowed to carry out regeneration treatment, for example, there is wheat straw on the road. Fuel, then the driver may turn the regeneration prohibition switch on, so that the regenerative state of the vehicle is a prohibited regeneration state. However, after the driver turns on the switch, after driving out the road, the driver forgets to cancel the switch, and the vehicle cannot perform the regeneration process normally.

In this case, the present application assumes that the dangerous state of the road disappears after the vehicle has traveled for a distance, so in this case (ie, the running state of the vehicle is a low speed driving state, and the vehicle is in a safe position, and The regenerative state of the vehicle is a prohibited regeneration state. After the vehicle starts from the prohibition regeneration state to the driving preset distance distance, the external environment type of the vehicle is determined, and the external environment type of the vehicle at this time is determined as the safety environment type. The target regeneration state corresponding to the safety environment type is the allowable regeneration state, and if the regeneration state of the vehicle does not coincide with this, it can be determined that the regeneration state of the vehicle needs to be adjusted.

If the driving state of the vehicle is a high-speed driving state, the above special circumstances may also occur. Therefore, it is also necessary to determine the external environment type of the vehicle after the vehicle starts from the prohibited regeneration state to the driving preset distance distance, and the external environment type of the vehicle at this time. Determined as the type of security environment. The target regeneration state corresponding to the safety environment type is the allowable regeneration state, and if the regeneration state of the vehicle does not coincide with this, it can 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 judge the position of the vehicle, because the vehicle traveling at a high speed does not pose a serious safety hazard to a fixed dangerous place.

Thus, in the above 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 allowable regeneration state, thereby ensuring the normal execution of the vehicle regeneration processing flow.

It should be noted that, in the above special application scenario, in order to confirm whether the driver forgets to cancel the regeneration prohibition switch, after the vehicle travels a predetermined distance, the regeneration state of the vehicle is determined again, and the regeneration state is compared with the target regeneration state. .

S205: Adjust the regeneration state of the vehicle if it is necessary to adjust the regeneration state of the vehicle.

Among them, one mode of adjusting the regeneration state of the vehicle is to adjust the state of the regeneration prohibition switch, or alternatively, the regeneration state of the vehicle is directly set by the control unit.

It can be seen from the above technical solution that the present application provides a vehicle regeneration control method, which can realize distance measurement between a vehicle and a set location that is unsuitable for regeneration, and simultaneously recognize a vehicle running state and a driver regeneration prohibition switch demand state. It can realize independent judgment of the vehicle's demand for regeneration prohibition at static, low speed and high speed, effectively avoiding the situation that the driver forgets to press the regeneration prohibition switch, causing the vehicle to regenerate in an area unsuitable for regeneration and increase the vehicle risk factor. It is also possible to prevent the driver from pressing the regeneration prohibition switch for a long time, and the vehicle does not enter the regeneration process, and the vehicle after-treatment box is blocked due to excessive carbon deposition.
