[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] The vehicle gear condition analysis method provided in this application embodiment can be applied to, for example... Figure 1 The application environment shown above includes a terminal 102 and a vehicle 104. Specifically, the terminal 102 first acquires the vehicle's basic data, vehicle operation data, and vehicle driving status. Based on the transmission type and vehicle driving status, it determines the first vehicle gear. Then, the terminal 102 acquires the gear change time and the corresponding engine speed change value of the vehicle 104. Based on the first vehicle gear and the engine speed change value, it determines the second vehicle gear after the gear change. Finally, the terminal 102 performs a gear condition analysis on the vehicle 104 based on the first and second vehicle gears.

[0044] In one embodiment, such as Figure 2 As shown, a method for analyzing vehicle gear operating conditions is provided, which can be applied to... Figure 1 Taking the terminal in the example, the explanation includes the following steps:

[0045] S202. Obtain basic vehicle data and vehicle operation data. Basic vehicle data includes transmission type, drive axle ratio, and tire rolling radius. Vehicle operation data includes engine speed, vehicle speed, torque percentage, and throttle opening.

[0046] The basic vehicle data is obtained from the basic vehicle information database. The terminal creates the basic vehicle information database by integrating the MES system (Manufacturing Execution System), ERP system (Enterprise Resource Planning), and related business-side databases. The basic vehicle information database is stored in Hive and is updated as the vehicle data is updated.

[0047] Vehicle operation data is stored in a Hive database and is collected by the vehicle network during the target time period. After the terminal obtains the vehicle operation data, it groups the data according to the vehicle chassis number and performs data cleaning on the grouped data. The data cleaning includes removing null values, converting field formats, escaping fields, and filtering data.

[0048] After acquiring basic vehicle data and vehicle operation data, the terminal will correct and thoroughly clean the vehicle speed signal based on the characteristics of vehicle network data quality and gear calculation services, and add three fields—mileage, time, and fuel consumption—to the data using the following formula: In the formula, mile is the distance (km), time is the time (h), fuel is the fuel consumption (L), v is the corrected speed, f is the sampling frequency, and fu is the instantaneous fuel consumption.

[0049] S204. Obtain the vehicle's driving status and determine the first vehicle gear based on the transmission type and the vehicle's driving status. The transmission type includes manual transmissions and electromechanical automatic transmissions. The vehicle's driving status includes normal driving in gear, coasting in gear, reversing, and coasting in neutral.

[0050] The terminal determines the vehicle's basic data based on the vehicle chassis number and confirms the data's validity. If the vehicle's basic data is missing, it searches for valid vehicle basic data for a vehicle with the same model in the vehicle basic information database and replaces the missing vehicle basic data with the valid vehicle basic data. Then, it determines the transmission type based on the vehicle's basic data. The transmission type includes manual transmissions and electromechanical automatic transmissions. After determining the transmission type, the terminal determines the first vehicle gear based on the vehicle's driving status.

[0051] If the transmission type is manual and the vehicle is in normal driving mode with gears engaged, the gear ratios can be calculated using the following formula:

[0052]

[0053] In the formula, n is the engine speed, v is the vehicle speed, and i o For the drive axle speed ratio, x i is the gear ratio of the transmission, and r is the tire rolling radius.

[0054] After determining the vehicle's gear ratios, the first gear is determined according to the following inequality:

[0055]

[0056] In the formula, This is the lower limit of the speed ratio for the i-th gear. This represents the upper limit of the speed ratio in the i-th gear. α: Gearbox constant speed ratio range, x i : The gear ratio of the i-th gear, x i+1 : Gear ratio of the (i+1)th gear, x i-1 : The gear ratio of the (i-1)th gear, where X is the gear of the ith gear.

[0057] If the transmission type is an electromechanical automatic transmission and the vehicle is in normal driving mode with the gear engaged, the first vehicle gear is determined by mapping the collected gear position signal identifier to the specific gear position field.

[0058] S206. Obtain the time of gear change and the corresponding engine speed change value, and determine the second vehicle gear after the gear change based on the first vehicle gear and the engine speed change value.

[0059] The number of gears in a vehicle is determined based on the type of transmission. There are m types of gears in a vehicle, specifically including neutral, 1st gear, 2nd gear... top gear and reverse. Then, the shift sequence is assigned to each gear based on the gear position markings, totaling... There are various shift sequence indicators, each indicated by (g) i ,g j ) indicates that, For the total number of gear shifting sequences, g i The gear indicator before shifting gears, g j This is the gear indicator after shifting gears.

[0060] Specifically, the terminal determines the shift timing based on the clutch signal or gear change, and determines the shift process based on the shift timing and the engine speed change during upshifting and downshifting. The data during the shift process is recorded as [g]. i g j ], count all in sequence The data from the gear shifting process is stored in a database.

[0061] S208. Based on the gear position of the first vehicle and the gear position of the second vehicle, perform gear condition analysis on the vehicle.

[0062] The analysis of vehicle gears includes two parts: analyzing a single vehicle gear and analyzing the gear shifting process. For a single vehicle gear, the analysis can be performed by considering the distribution of different engine speeds in different gears, the distribution of different vehicle speeds in different gears, the ratio of vehicle mileage in different gears to total vehicle mileage, the ratio of the duration of different gears to total vehicle driving time, and the vehicle's average fuel consumption. The analysis can be performed by considering changes in vehicle speed, engine speed, throttle opening, torque, and vehicle gradient during gear shifts.

[0063] The aforementioned vehicle gear condition analysis method first acquires basic vehicle data and vehicle operating data. Basic vehicle data includes transmission type, drive axle ratio, and tire rolling radius. Vehicle operating data includes engine speed, vehicle speed, torque percentage, and throttle opening. Then, the vehicle's driving state is acquired, and the first vehicle gear is determined based on the transmission type and driving state. Transmission types include manual transmissions and electromechanical automatic transmissions. Vehicle driving states include normal driving in gear, coasting in gear, reversing, and coasting in neutral. Next, the moment of gear change and the corresponding engine speed change value are acquired. Based on the first vehicle gear and the engine speed change value, the second vehicle gear after the gear change is determined. Finally, based on the first and second vehicle gears, a gear condition analysis is performed. The method provided in this application performs gear condition analysis based on the first vehicle gear before the gear change and the second vehicle gear after the gear change, enabling analysis of the operating conditions during the gear change process.

[0064] In some embodiments, such as Figure 3 As shown, Figure 3 This is a flowchart illustrating a method for determining the first vehicle gear in one embodiment. The method, based on the transmission type and vehicle driving state, includes: if the transmission type is a manual transmission and the vehicle is in normal driving with gear, then the gear ratio is calculated based on engine speed, vehicle speed, drive axle ratio, and tire rolling radius; and the first vehicle gear is determined based on the gear ratio. If the transmission type is an electromechanical automatic transmission and the vehicle is in normal driving with gear, then a gear position signal is acquired; and the first vehicle gear is determined based on the gear position signal.

[0065] In this step, the terminal first determines the transmission type, then determines the vehicle's driving status, and finally determines the first vehicle gear based on the transmission type and the vehicle's driving status.

[0066] The method provided in this step determines the first vehicle gear based on the transmission type and vehicle driving status, making the determined vehicle gear more accurate.

[0067] In some embodiments, obtaining the vehicle driving status includes: determining whether the vehicle meets preset coasting conditions, the preset coasting conditions including vehicle speed greater than a first preset vehicle speed, engine speed greater than a preset engine speed, torque percentage being a preset torque percentage, and throttle opening being a preset throttle opening; if the vehicle meets all preset coasting conditions, then the vehicle driving status is determined to be vehicle coasting in gear.

[0068] In this step, if the vehicle's transmission type is a manual transmission, the vehicle's driving state is determined directly based on the preset coasting conditions. If the vehicle's transmission type is an electronically controlled mechanical automatic transmission, the vehicle's current gear is first checked to see if it is positive. If the current gear is positive, the vehicle's driving state is determined based on the preset coasting conditions. For example, the preset coasting conditions could be a vehicle speed greater than 2 km / h, an engine speed greater than 700 r / min, a torque percentage of 0%, and a throttle opening of 0%.

[0069] The method provided in this step determines whether the vehicle is coasting in gear based on preset coasting conditions, which can more accurately determine the current state of the vehicle.

[0070] In some embodiments, obtaining the vehicle driving status further includes: determining whether the vehicle meets preset neutral coasting conditions, wherein the preset neutral coasting conditions include the vehicle being in neutral and the vehicle speed being a second preset speed; if the vehicle meets all preset neutral coasting conditions, then the vehicle driving status is determined to be vehicle coasting in neutral.

[0071] In this step, when the vehicle is in neutral and the speedometer reads 0, the vehicle's driving state is determined to be coasting in neutral.

[0072] The method provided in this step determines whether the vehicle is coasting in neutral based on preset neutral coasting conditions, which can more accurately determine the current state of the vehicle.

[0073] In some embodiments, a gear condition analysis is performed on the vehicle based on the first vehicle gear and the second vehicle gear, including: obtaining the mileage, driving time, and fuel consumption of the vehicle when it is in the first vehicle gear, and obtaining the total mileage and total driving time during the vehicle's driving process; determining a mileage ratio based on the mileage and total mileage, determining a time ratio based on the driving time and total driving time, and determining an average fuel consumption based on the fuel consumption and mileage; and performing a gear condition analysis on the vehicle based on the first vehicle gear, vehicle speed, engine speed, mileage ratio, time ratio, and average fuel consumption.

[0074] In this step, the terminal first obtains the mileage M of the vehicle when it is in each gear. i Travel time T i and fuel consumption rate F i And obtain the total mileage M0 and total driving time T0 during the vehicle's journey, and then apply the formulas respectively. as well as Calculate the mileage ratio m when the vehicle is in each gear. i Duration ratio t iand average fuel consumption f i The bar chart showing the average fuel consumption for each gear is as follows: Figure 4 As shown.

[0075] The terminal calculates the mileage traveled by the vehicle in each gear within each engine speed range based on the engine speed distribution in different gears. This mileage, along with the total mileage M0, is used to perform a vehicle operating condition analysis. For example, if the vehicle has i gears and j engine speed distribution ranges of 500-600 r / min, 600-700 r / min, ..., 1900-2000 r / min, the calculation is based on the formula... Calculate the mileage ratio M corresponding to each engine speed distribution range. ij And according to M ij Perform operating condition analysis on the vehicle.

[0076] The terminal calculates the mileage traveled by the vehicle in each gear and within each speed range based on the vehicle's speed distribution in different gears. It then performs a performance analysis on the vehicle based on this mileage and the total mileage M0. For example, if the vehicle has i gears and k speed ranges (0-10 km / h, 10-20 km / h…110-120 km / h), the calculation is performed using the formula… Calculate the mileage ratio M corresponding to each speed distribution interval. ik And according to M ik Perform operating condition analysis on the vehicle.

[0077] The method provided in this step analyzes the vehicle's gear condition based on the first vehicle's gear, vehicle speed, engine speed, mileage ratio, time ratio, and average fuel consumption, enabling a more comprehensive analysis of the condition of a single gear.

[0078] In some embodiments, the gear condition analysis of the vehicle based on the first vehicle gear and the second vehicle gear further includes: acquiring changes in vehicle operating data during the process of the vehicle changing from the first vehicle gear to the second vehicle gear, including changes in vehicle speed, engine speed, throttle opening, torque, and vehicle gradeability; and performing gear condition analysis of the vehicle based on all changes in vehicle operating data.

[0079] In this step, the terminal performs a condition analysis on the vehicle's gear shifting process based on changes in vehicle speed, engine speed, throttle opening, torque, and vehicle gradient, and stores the analysis results in a database. The throttle opening changes are shown below. Figure 5 As shown.

[0080] The method provided in this step analyzes the operating conditions of a vehicle during gear shifting based on changes in vehicle operating data, making the analysis of the operating conditions during gear shifting more accurate.

[0081] In one embodiment, another method for analyzing vehicle gear conditions is provided, which includes data preprocessing, gear calculation, gear condition analysis, upshift / downshift frequency analysis, and gear shifting process analysis.

[0082] (1) Data preprocessing

[0083] Based on the required vehicle information, basic vehicle information is obtained. A basic vehicle information database is created through the integration of MES, ERP systems, and related business-side databases. This database mainly includes: vehicle chassis number, TBOX terminal number, vehicle model, engine model, transmission model, transmission gear ratios, drive axle model, drive axle final drive ratio, tire model, and tire rolling radius. This basic vehicle information database is stored in Hive and is updated along with vehicle and data updates in the production system.

[0084] Based on the required vehicles and target time period, SparkSQL is used to extract relevant vehicle operation data collected from the Hive database, mainly including: longitude, latitude, altitude, heading angle, GPS vehicle speed, instrument speed, engine speed, throttle, torque, instantaneous fuel consumption, clutch signal, neutral signal, reverse gear signal, and gear position signal. Then, the data is grouped according to chassis number, and the grouped data undergoes data cleaning, mainly including removing null values, converting field formats, escaping fields, and filtering data.

[0085] Based on the characteristics of vehicle network data quality and gear calculation services, the vehicle speed signal is corrected and thoroughly cleaned using the following formula: Add three fields to the data: mileage (km), time (h), fuel (L), v (corrected speed), f (sampling frequency), and fu (instantaneous fuel consumption).

[0086] (2) Gear Calculation

[0087] Based on the preprocessed data grouped by chassis number, the system queries the vehicle's basic information by chassis number and identifies the transmission model. Depending on the transmission type, there are two calculation processes: MT (manual transmission) and AMT (automatic manual transmission).

[0088] For manual transmissions (MT), the basic configuration information is retrieved by chassis number. This information includes the gear ratios of each gearbox, tire rolling radius, and final drive ratio, and the validity of the data is verified. If the basic configuration information for the vehicle is missing, valid basic configuration information for vehicles with the same model is searched in the vehicle basic information database. The gear ratios corresponding to each row in the vehicle data are then calculated using a formula. Where n: engine speed, v: vehicle speed, i o Drive axle speed ratio, i g : Gear ratio of the transmission, r: tire rolling radius, and then match the specific gear information corresponding to each line.

[0089] Reverse gear detection: If the reverse gear switch is on, it is determined to be in reverse gear; Coasting in gear detection: If the vehicle speed is >2km / h, the engine speed is >700r / min, the torque percentage is 0%, and the throttle opening is 0%, it is determined to be in gear; Neutral gear detection: If the neutral gear switch is on, and the speed is 0km / h, it is determined to be in neutral; Coasting in neutral: If the neutral gear switch is on, and the speed is 0km / h, it is determined to be in neutral; Normal driving gear detection: After filtering out the above data, based on... satisfy Where X is the gear ratio value calculated for each row. The lower limit of the gear ratio in gear i. The upper limit of the gear ratio in gear i, α: the range of constant gear ratios in the transmission, x i : The gear ratio of the i-th gear, x i+1 : Gear ratio of the (i+1)th gear, x i-1 : The gear ratio of the (i-1)th gear. The final calculation yields the i-th gear corresponding to X.

[0090] The AMT transmission works as follows: Based on the collected gear position signal identifier, it maps to the specific gear position field, and adds other gear judgment logic on this basis: Reverse gear judgment: If the current gear is negative, it is judged as reverse gear; Coasting in gear judgment: If the current gear is positive, and the vehicle speed is >2km / h, the engine speed is >700r / min, the torque percentage is 0%, and the throttle opening is 0%, it is judged as coasting in gear; Neutral gear judgment: If the current gear is 0 and the speed is 0km / h, it is judged as neutral; Coasting in neutral: If the forward gear is 0 and the speed is 0km / h, it is judged as coasting in neutral.

[0091] (3) Gear condition analysis

[0092] Define the gear positions as: Neutral, 1st gear, 2nd gear... highest forward gear of the transmission, reverse gear, coasting in neutral, coasting in gear.

[0093] Calculate the proportion of mileage and time for each gear tag, calculate the total mileage M0 and total time T0 for all data, and then filter the data for gear tag i in turn to calculate the total mileage M under that gear tag. i Total time T i Then through the formula Calculate the percentage of mileage and time for each gear level label.

[0094] Calculate the average fuel consumption under each gear label, filter the data for gear label i in turn, and calculate the total mileage M under that gear label. i And total fuel consumption F i Then through the formula Calculate the average fuel consumption for each gear rating.

[0095] Calculate the distribution chart of gear labels and engine speed segments. Gears are segmented according to their labels, and engine speeds are segmented according to 500-600 r / min, 600-700 r / min, ..., 1900-2000 r / min. Data that matches gear segment i and engine speed segment j are selected sequentially, and the mileage M of that data is calculated. ij Through formula Calculate each value of the gear label and speed distribution.

[0096] Calculate the distribution map of gear labels and vehicle speed segments. Gears are segmented according to gear labels, and engine speeds are segmented according to 0-10km / h, 10-20km / h…110-120km / h. Data that matches gear segment i and vehicle speed segment j are selected sequentially, and the mileage M of this data is calculated. ij Through formula Calculate each value of the gear label and vehicle speed distribution.

[0097] (4) Analysis of the number of gear shifts

[0098] The number of gears is determined based on the gearbox model, and gear identifiers are defined: neutral, 1st gear, 2nd gear... highest gear, reverse, totaling m categories. Furthermore, based on the gear identifiers, the shift sequence identifiers for all gears are defined, totaling... Each type of shift indicator is represented by (g) i ,g j ) identifier, where, For permutations and combinations, g i : The i-th gear indicator, g j : The j-th gear indicator.

[0099] Specifically, the shift point is determined based on the clutch signal or gear change, and the gear before the shift is denoted as g. i The gear after shifting is denoted as G. j And accumulate the shift indicator (g) i,g j The number of times each gear shift indicator is counted is recorded in Table 1.

[0101]

[0102] (5) Gear shifting process analysis

[0103] The shift point is determined based on the clutch signal or gear change. The shift process is then determined based on the sudden changes in engine speed during upshifts and downshifts. The gear position before the shift is denoted as g. i The gear after shifting is denoted as G. j Shift indicator (g) i ,g j The shift process data is recorded as [g] i ,g j The system sequentially collects data from all gear shifting processes and stores it in the database.
