[0074] The present invention collects basic vehicle information, determines driving regeneration conditions, and performs relevant data statistics and fuel consumption calculations, thereby being able to provide reminders for driving regeneration related information.

[0075] It should be noted that according to statistics, the number of motor vehicles in my country has continued to grow, and it has become the world's largest producer and seller of motor vehicles for eleven consecutive years. In 2019, the number of motor vehicles in China reached 348 million. In August 2020, the Ministry of Ecology and Environment released the "China Mobile Source Environmental Management Annual Report (2020)", which showed that the emissions of four pollutants from motor vehicles, carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOX), and particulate matter (PM), were 7.716 million tons, 1.892 million tons, 6.356 million tons, and 74,000 tons, respectively. Automobiles are the main contributors to the total amount of pollutant emissions, and their emissions of CO, HC, NOX, and PM exceed 90%. Diesel vehicles emit more than 80% of the total NOX emissions of automobiles, and more than 90% of PM emissions.

[0076] Since pollutants in diesel vehicle exhaust are emitted near the ground and are located in the human respiratory zone, they can easily induce various respiratory diseases in the human body. Therefore, nitrogen oxides and particulate matter in diesel vehicle exhaust not only pollute the environment, but also endanger human health.

[0077] According to the requirements of GB17691-2018, from July 1, 2021, all diesel vehicles nationwide will begin to implement the National VI a limit requirements; from July 1, 2023, the emission standards of all diesel vehicles nationwide will be further upgraded to National VI b. The new National VI standard has significantly tightened the emission indicators of diesel vehicles, and the various exhaust emission limits have been significantly reduced. At present, the National VI era has arrived, and the country has higher requirements for vehicle particulate matter emissions. In order to make the particulate matter emissions in the exhaust gas meet the National VI standard, National VI vehicles have been generally equipped with an important component-DPF (diesel particulate matter filter), which is used to capture harmful particulate matter in the exhaust to achieve the effect of reducing particulate matter PM emissions.

[0078] The process of DPF filtering and oxidizing harmful particles in the collected exhaust gas is called DPF regeneration. During the driving process of commercial vehicles, when the conditions are met, the ECU automatically controls the regeneration. The process of oxidizing and consuming particulate matter without human intervention is called driving regeneration. This process converts particulate matter into harmless gas and then discharges it into the atmosphere. The efficient completion of this process will achieve energy-saving, environmentally friendly and intelligent treatment of particulate matter captured by DPF.

[0079] In recent years, with the continuous rise in fuel prices, the continuous increase in the number of commercial vehicles, and the impact of factors such as the epidemic, the freight prices of commercial vehicle road transportation have continued to fall, and many fleets or individual vehicles have been in a situation of insufficient profitability or even loss-making for a long time. Therefore, it is of great significance to clarify the risk points of fuel waste in the vehicle operation process and realize the digitization of fuel consumption in driving regeneration events to assist drivers in making driving regeneration behavior decisions, reduce fuel consumption and promote National VI driving regeneration training.

[0080] At present, major domestic commercial vehicle manufacturers or engine manufacturers have not compiled and opened driving regeneration fuel consumption data to users, and user training for National VI vehicle regeneration mainly relies on offline links such as vehicle delivery, first vehicle maintenance and three guarantees for emission parts, with sales and service personnel providing face-to-face training to users.

[0081] Therefore, the prior art solution has the following disadvantages:

[0082] First, the existing technical solutions require drivers to understand and memorize the principles of commercial vehicle computers and numerous operating points during offline training before they can apply the corresponding operating specifications to the use and maintenance of National VI vehicles;

[0083] Second, the existing offline training programs are limited by the service resources of commercial vehicle manufacturers, making it difficult to provide full coverage and repeated training for drivers in the National VI driving regeneration training;

[0084] Third, the existing offline training program does not have the ability to make targeted real-time reminders based on the actual operating scenarios of vehicle driving regeneration;

[0085] Fourth, currently vehicle manufacturers and engine manufacturers are focusing on the development of new National VI products and problem solving. After-sales driving regeneration training is mainly offline, and rarely involves online real-time voice reminders, online training and the digitization of driving regeneration events.

[0086] In view of the problems existing in the above-mentioned prior art, the embodiments of the present invention develop a driving regeneration monitoring model to monitor the occurrence of driving regeneration during the operation of the in-cylinder post-injection National VI vehicle. And the driving regeneration data of the user's vehicle operation is collected in real time through the on-board terminal equipment installed on the vehicle. After the user's business trip is completed, the driving regeneration frequency, interruption frequency, driving regeneration theoretical fuel saving space, actual fuel saving space and the estimated remaining mileage for the next driving regeneration trigger are pushed through the mobile phone APP. Vehicles with a history of successful driving regeneration will broadcast the National VI driving regeneration event to the driver when the driving regeneration is triggered again. The present invention will digitize the fuel consumption data related to the driving regeneration event, and use voice broadcast to facilitate the driver to make driving regeneration behavior decisions.

[0087] Based on the above scheme, in order to facilitate a better understanding of the driving regeneration information reminder method provided by the embodiment of the present invention, the following is a detailed description:

[0088] See also Figure 2 The implementation process of the present invention includes data collection, data processing, vehicle condition analysis, data calculation, voice reminder, fuel consumption calculation, effect analysis, visualization and other main processes, among which:

[0089] 1. Data collection mainly includes vehicle speed, DPF regeneration mode, comprehensive carbon load, post-injection fuel volume, driving regeneration carbon load threshold, etc. during vehicle operation.

[0090] 2. Data processing includes completing data preprocessing, etc.

[0091] 3. Vehicle condition analysis includes vehicle status identification of driving regeneration start, driving regeneration end, parking regeneration start, parking regeneration end, driving regeneration interruption and driving regeneration completion;

[0092] 4. Data calculation includes calculation of the minimum carbon load threshold for triggering driving regeneration, the remaining mileage to the next driving regeneration, and the actual carbon load consumed in a single regeneration process of driving regeneration or parking regeneration;

[0093] 5. Voice reminders include when there is a record of successful driving regeneration in the historical business trip of the bicycle, when the driving regeneration is triggered, the driving regeneration is successful, and the driving regeneration is interrupted, the APP pushes the corresponding voice reminder.

[0094] 6. Fuel consumption calculation includes calculation of actual fuel saving space caused by driving regeneration completion event after the business trip, if there is a driving regeneration completion event during the business trip, and theoretical fuel saving space caused by driving regeneration failure and parking regeneration during the trip.

[0095] 7. The effect analysis includes the number of driving regenerations during the vehicle's business trip, the number of driving regeneration interruptions, the actual fuel saving space, the actual wasted fuel consumption (theoretical fuel saving space), the remaining mileage to the next driving regeneration and other data.

[0096] 8. Visualization includes the number of driving regenerations, the number of driving regeneration interruptions, the actual fuel saving space, the actual wasted fuel consumption (theoretical fuel saving space), the remaining mileage to the next driving regeneration and other data visualization.

[0097] The implementation methods of each process are as follows:

[0098] Data collection:

[0099] 1.1. The embodiment of the present invention adopts the method of installing a vehicle-mounted terminal device on the vehicle, and collecting vehicle operation data (vehicle basic data) in real time through the vehicle-mounted terminal device.

[0100] 1.2. The operating data collected by the vehicle terminal equipment includes vehicle speed, DPF regeneration mode, comprehensive carbon load, post-injection 1 fuel volume, post-injection 2 fuel volume, cycle injection volume and other data.

[0101] Data processing:

[0102] 2.1 The collected data will first be stored in the vehicle terminal device, and then transmitted back to the data collection platform through the mobile network. According to the data usage requirements, the platform will pre-process the collected data before the data participates in calculations or logical judgments, and complete the missing data. Data pre-processing rules: Loss = 1s, completion rules follow the ETL unified completion rules.

[0103] Vehicle condition analysis:

[0104] 3.1. The embodiment of the present invention uses the collected DPF regeneration mode status, comprehensive carbon load value and vehicle speed data to determine the status of a total of 6 vehicle conditions: driving regeneration start, parking regeneration start, driving regeneration end, parking regeneration end, driving regeneration interruption and driving regeneration completion.

[0105] 3.2. Regeneration starts:

[0106] a. Driving regeneration starts: during driving, the DPF regeneration mode changes from 0 to non-0, and the comprehensive carbon load is greater than 5g;

[0107] Parking regeneration starts: DPF regeneration mode changes from 0 to non-0 in parking state, and the comprehensive carbon load is greater than 5g;

[0108] b. Carbon load M1 at the start of driving regeneration / parking regeneration: When DPF regeneration mode is > 0, the first second corresponds to the comprehensive carbon load value M1;

[0109] 3.3. End of regeneration:

[0110] a. Driving regeneration / parking regeneration ends: DPF regeneration mode changes from non-0 to 0; that is, DPF regeneration mode = 0;

[0111] b. Carbon load at the end of regeneration M2: the comprehensive carbon load value M2 when the DPF regeneration mode changes from non-0 to 0;

[0112] 3.4. Driving regeneration interruption and driving regeneration completion: After the driving regeneration is completed, if the comprehensive carbon load M2 is higher than a certain threshold (for example, M2>5g), it is judged that the driving regeneration is interrupted; if M2≤5g, it is judged that the driving regeneration is completed.

[0113] It should be noted that in the embodiment of the present invention, "DPF regeneration mode" is one of the vehicle parameters collected by the vehicle terminal device, 0 represents that the vehicle is not regenerated, and non-0 represents that regeneration has started. When the carbon load of the vehicle accumulates to the driving regeneration trigger threshold, the driving regeneration starts after the driving regeneration condition is met during the driving process of the vehicle. As the driving regeneration proceeds, the injector continues to post-inject diesel, and the diesel is oxidized and releases heat in the DOC. After the heat enters the DPF with the exhaust gas, the carbon load in the DPF is gradually oxidized and reduced at high temperature. When the carbon load is reduced to below the calibration threshold, the regeneration mode changes from non-0 to 0, and the driving regeneration ends. When the carbon load accumulates to the parking regeneration trigger threshold, the vehicle is in the parking state. After the driver presses the parking regeneration switch, the vehicle parking regeneration starts. After controlling the throttle and hydrocarbon injection components, the post-processing temperature is increased to the set value, and the carbon load is gradually oxidized and reduced at high temperature. When the carbon load is reduced to below the calibration threshold, the regeneration mode changes from non-0 to 0, and the parking regeneration ends.

[0114] Data operations:

[0115] The embodiment of the present invention mainly needs to calculate the minimum carbon load threshold for triggering driving regeneration, the actual carbon load consumed in a single regeneration process of driving regeneration or parking regeneration, and the remaining mileage to the next driving regeneration.

[0116] 4.1. Learning method of the minimum carbon load threshold for triggering driving regeneration:

[0117] (1) When the DPF regeneration mode changes from non-0 to 0 during driving, record the comprehensive carbon load value at the beginning of driving regeneration;

[0118] (2) Learn the comprehensive carbon load value at the beginning of each driving regeneration, record the minimum carbon load value M3 that triggers driving regeneration, apply it to each subsequent driving cycle, and iteratively update the threshold.

[0119] 4.2. Calculation of carbon removal during a single driving regeneration or parking regeneration:

[0120] (1) The actual carbon load consumed in a single regeneration process of driving regeneration or parking regeneration is M1-M2;

[0121] 4.3. Calculation of the remaining mileage until the next driving regeneration:

[0122] (1) Taking business trips as units, the carbon load cumulative acceleration rate of each business trip (the total cumulative carbon load of the business trip divided by the total mileage) is calculated, and the minimum carbon load cumulative acceleration rate of the last five business trips is taken as the benchmark. The minimum carbon load cumulative acceleration rate is calculated in an iterative manner.

[0123] (2) Based on the minimum value of the cumulative acceleration rate of the carbon load of the last five business trips, after each business trip, the remaining mileage until the next driving regeneration trigger is calculated based on the difference between the current comprehensive carbon load value on the vehicle and the driving regeneration trigger threshold M3.

[0124] Voice reminder: The embodiment of the present invention determines the start of driving regeneration, completion of driving regeneration and interruption of driving regeneration based on the collected parameters such as vehicle speed, comprehensive carbon load and DPF regeneration mode (see 3.1-3.4 for the judgment method). When there is a record of successful driving regeneration in the historical business trip of a single vehicle, and the start of driving regeneration, completion of driving regeneration and interruption of driving regeneration in the business trip are triggered again, a corresponding voice reminder is provided.

[0125] Fuel consumption calculation:

[0126] 6.1 Calculation of theoretical fuel saving space when driving regeneration is frequently interrupted:

[0127] (1) When driving regeneration occurs, the theoretical fuel saving space is not calculated after the driving regeneration is completed;

[0128] (2) If M1-M2≤0, the amount of fuel injected after injection 1 and after injection 2 during the DPF regeneration mode>0 is integrated as the fuel saving space Q1;

[0129] It should be noted that if M1-M2≤0, it means that the carbon load has not decreased during the regeneration process from the start of driving regeneration to the end of driving regeneration, and the carbon load at the end of regeneration is increased compared to the carbon load at the beginning of regeneration. The common reasons are that the driving regeneration time is too short due to the driver stopping midway or the speed is too low, the driving regeneration is interrupted, and the driving regeneration does not reach the stage of reducing the carbon load. Instead, the driving regeneration process increases the accumulation of carbon load.

[0130] In this embodiment, post-injection 1 and post-injection 2 are two stages in the regeneration process. Post-injection 2 is the diesel injection after the main injection of the injector. The function of post-injection 2 is to promote the temperature increase of the exhaust gas after-treatment system. The function of post-injection 1 is to bring the hydrocarbons (diesel) required for the exothermic reaction of the after-treatment to the oxidation catalyst of the after-treatment. After the diesel is oxidized in the after-treatment, the temperature of the after-treatment is increased to the required temperature for reducing the carbon load.

[0131] (3) If M1-M2>0, the comprehensive carbon load decreases for 5 consecutive seconds, and the first second of the decrease is taken as the start time of regeneration and carbon elimination. Calculate the amount of post-injection 1 and post-injection 2 between the start of driving regeneration and the start time of regeneration and carbon elimination, and then sum them up as the total fuel consumption Q2 in the warm-up stage. Calculate the fuel consumption in the warm-up stage per gram of carbon load at the start of this driving regeneration and use this as the benchmark. After the regeneration is not completed, calculate the wasted fuel in the warm-up stage based on the remaining carbon load M2 after the regeneration is completed, that is: Q2 / M1*M2.

[0132] (4) Parking regeneration fuel consumption: If parking regeneration occurs, the parking regeneration fuel consumption Q3 is calculated based on the integral of the cycle injection amount during the parking regeneration process;

[0133] (5) Theoretical fuel saving space Q = Q1 + Q2 / M1 * M2 + Q3.

[0134] 6.2 Calculation of actual fuel saving space when driving regeneration is successful:

[0135] (1) The total fuel consumption and total carbon load of all driving regeneration interruptions and parking regeneration events in all historical data of the vehicle. The fuel consumption per gram of carbon load consumed is Q4 = total fuel consumption / total carbon load.

[0136] (2) In a single business trip, the total fuel consumption and total carbon load consumed by the vehicle regeneration completion event, the fuel consumption per gram of carbon load consumed Q5 = total fuel consumption / total carbon load.

[0137] (3) Actual fuel saving space = (Q4-Q5)*total carbon load consumed by the vehicle regeneration completion event; it should be noted that if Q5 is greater than Q4, the actual fuel saving space will not be pushed for this business trip.

[0138] (4) When there is no driving regeneration interruption and parking regeneration in the historical data, the actual fuel saving space is not pushed (historical data without driving regeneration interruption and parking regeneration means that in the historical data of a single vehicle, all driving regenerations that occurred can be completed, that is, no driving regeneration interruption or parking regeneration occurs.

Under this condition, the driving regeneration success rate is very high, and there is a possibility that all driving regenerations can be completed). When there is no successful driving regeneration in a single business trip, the actual fuel saving space is 0, and the actual wasted fuel consumption (theoretical fuel saving space) is pushed.
