Wherein, as an example, the step of calculating real-time gear vehicle speed data based on the vehicle condition data may comprise the sub-steps of:

and S31, calculating a vehicle-mounted weight value by using the vehicle condition data.

Wherein the vehicle-mounted weight value may be a load value of the vehicle.

Referring to fig. 8, a flowchart of an operation of calculating the vehicle-mounted weight value according to an embodiment of the present invention is shown.

Wherein, as an example, step S31 may comprise the following sub-steps:

s311, obtaining a preset oil consumption distribution map and on-line operation data of the vehicles, wherein the oil consumption distribution map is obtained by calculating and summarizing engine constants and historical operation data of a plurality of vehicles.

In one embodiment, the prior operation data may include a vehicle speed, an engine speed, an injection amount and a mileage of the vehicle, and the like; then, some data without reference meaning, such as data with too high or too low vehicle speed or small driving mileage, are removed from the data. And then calculating the average oil consumption of hundred kilometers and the average vehicle speed by using the engine constant and the cycle number of the cylinders, and manually marking the vehicle load under the average oil consumption and the average vehicle speed. And counting the loads of the vehicles with the marks, summarizing the loads, and finally forming the oil consumption distribution graph.

The on-line operation data can be real-time vehicle speed, engine speed, fuel injection quantity and driving mileage of the vehicle and the like.

Referring to fig. 9, a flowchart illustrating an operation of calculating a vehicle unique mass according to an embodiment of the present invention is shown.

In a specific implementation, each vehicle can calculate the average oil consumption and the average vehicle speed of hundreds of kilometers by using an engine constant and the cycle number of cylinders, and manually mark the vehicle load under the average oil consumption and the average vehicle speed.

And S312, searching the preset oil consumption distribution map based on the online operation data to obtain a vehicle-mounted weight value.

And calculating the average oil consumption and the average vehicle speed of the corresponding hundred kilometers based on the online operation data, and searching in a preset oil consumption distribution diagram according to the calculated average oil consumption and the average vehicle speed to obtain a vehicle-mounted weight value.

And S32, acquiring driving demand data of the vehicle, and matching the driving demand data and the vehicle-mounted weight value to obtain required gear speed data from historical data.

In one embodiment, the driving demand data may be a user's vehicle driving demand. For example, acceleration demand recognition, hill climbing demand recognition, lane change overtaking demand recognition, or the like. The required gear speed data may be a gear and a speed required for the vehicle to travel in a state that the driving demand of the user is satisfied.

The acceleration requirement identification can comprehensively analyze the acceleration running requirement of the vehicle through the driving requirement information (the opening degree of an accelerator pedal) of the driver, the vehicle load information (an oil injector and air inlet pressure) and other necessary data information in the vehicle data, identify the requirement of the driver for acceleration running, and avoid inappropriate low-gear high-speed behavior judgment and reminding.

The climbing requirement identification can identify the ramp condition of the current vehicle driving road section through a gyroscope signal and a GPS signal which are arranged in the R-BOX, meanwhile, signals such as an accelerator pedal, fuel injection quantity, air inlet pressure, engine output torque and the like in vehicle data are combined, whether the vehicle is in a special climbing requirement working condition or not is judged, inappropriate low-gear high-speed behavior judgment and reminding are avoided, and matched climbing economic gears and engine rotating speed are calculated.

The lane-changing overtaking driving requirement identification can judge whether the vehicle is in a special requirement working condition of lane-changing overtaking driving or not at present by a gyroscope signal and a GPS signal which are arranged in the R-BOX, and simultaneously combining signals such as an accelerator pedal, fuel injection quantity, air inlet pressure, engine output torque and the like in vehicle data, avoid improper low-gear high-speed behavior judgment and reminding, and calculate matched overtaking economic gear and engine rotating speed.

After the driving demand data are determined, the driving demand data and the vehicle-mounted weight value can be utilized, required gear speed data are obtained from historical data in a matching mode, and therefore the current driving road condition information of the vehicle is analyzed, and the relation between the running demand of the vehicle and the gear speed matching demand is reasonably analyzed and calculated.

And S33, calculating real-time gear speed data based on the required gear speed data.

Because the required gear speed data is the gear and the speed which can meet the driving requirements of the user and is possibly close to the gear and the speed when the current user drives the vehicle, the real-time gear speed data can be calculated according to the required gear speed data so as to accurately identify the relation between the driving requirements of the vehicle and the matching of the gear speed and provide subsequent voice reminding interactive behaviors.

Referring to fig. 10, a first flowchart of calculating a gear according to an embodiment of the present invention is shown.

Wherein, as an example, step S33 may comprise the following sub-steps:

and S331, respectively acquiring the on-line gear speed data and the historical gear speed data of the vehicle.

The online gear speed data are real-time gear and speed of the vehicle, and the historical gear speed data are historical gear and speed of the vehicle driven by a user.

S332, performing cluster calculation on the online gear speed data, the historical gear speed data and the required gear speed data to obtain real-time gear speed data.

Specifically, the online gear speed data and the historical gear speed data can be subjected to cluster analysis to obtain gear characteristic data specific to the vehicle, and meanwhile, after the vehicle data are collected and calculated online, the current vehicle speed is obtained.

Referring to fig. 11, a second flowchart of calculating the gear according to an embodiment of the invention is shown.

Wherein, as an example, step S33 may comprise the following sub-steps:

s333, obtaining on-line gear speed data of the vehicle, and obtaining a gear speed ratio value of the vehicle type corresponding to the required gear speed data.

And S334, calculating a theoretical gear speed ratio corresponding to the required gear speed data according to the gear speed ratio, and calculating an online gear speed ratio corresponding to the online gear speed data according to the gear speed ratio.

And S335, summing and averaging the theoretical gear speed ratio and the online gear speed ratio to obtain real-time gear speed data.

Specifically, after the online gear vehicle speed data is obtained, a vehicle speed calculation formula can be used to convert a gear speed ratio calculation formula, wherein the influence of the actual rolling radius factor f of the tire is considered.

The gear speed ratio calculation formula is obtained as follows:

gear ratio = engine speed × 60 × 3.14 × tire diameter × f/(1000 × vehicle speed).

Then, a theoretical gear speed ratio (theoretical N/V value) of each gear can be calculated by calculating the correlation characteristics of each gear, the vehicle speed, and the engine speed. The current online gear speed ratio (the current N/V value) can be calculated at the same time by collecting the current speed and the engine speed information of the vehicle; and then comparing the theoretical gear speed ratio with the online gear speed ratio to obtain real-time gear speed data including gear and speed.

Wherein, as an example, the step of calculating ideal gear speed data based on the vehicle condition data may comprise the sub-steps of:

and S41, determining the driving road condition information based on the vehicle condition data.

The driving road condition information may be a road condition of the vehicle when the vehicle is currently driving, and specifically, different road conditions (such as a climbing road condition, a downhill road condition, and a congestion road condition) for the vehicle to drive may be identified through the collected vehicle operation parameter information, the driver driving behavior information, the driving demand information, the GPS information, the gyroscope information in the R-BOX, and the like.

And S43, calculating ideal gear vehicle speed data by adopting the ideal oil consumption value.

Specifically, the oil consumption corresponding to different vehicle conditions, different gears and different vehicle speeds is calculated through the vehicle-mounted machine mechanism data, then the driving working conditions corresponding to different oil consumption are determined, and then the different driving working conditions are constructed into a preset driving working condition list, so that the driving working condition list can be screened according to the driving road condition information, the lowest oil consumption of hundreds of kilometers under the driving road condition information is obtained, the corresponding gears and the vehicle speeds are calculated according to the oil consumption values, and the ideal gear vehicle speed data is obtained.

And S12, when the real-time gear speed data is different from the ideal gear speed data, counting the duration of the deviation.

After the real-time gear vehicle speed data and the ideal gear vehicle speed data are obtained through calculation, whether the real-time gear vehicle speed data and the ideal gear vehicle speed data are the same or not can be judged firstly, if the real-time gear vehicle speed data and the ideal gear vehicle speed data are different, the fact that the vehicle is in a high-oil-consumption driving state is proved, at the moment, the duration time of the difference between the real-time gear vehicle speed data and the ideal gear vehicle speed data can be counted, and whether voice prompt needs to be conducted on a user or not can be determined according to the duration time so as to correct the driving behavior of the user.

And S13, if the duration is longer than a first preset duration, generating and playing voice prompt information to prompt a user to correct the current driving gear.

When the duration is longer than the first preset duration, the vehicle is indicated to continuously run with high fuel consumption, and in order to reduce the fuel consumption, the voice prompt information can be immediately generated and played.

Specifically, the fuel consumption of one hundred kilometers can be calculated according to the real-time gear vehicle speed data accumulation, and a real-time fuel consumption value is obtained. The ideal oil consumption value of a hundred kilometers of the vehicle can be calculated according to the vehicle speed data of the ideal gear.

And S16, calculating a fuel consumption deviation value according to the real-time fuel consumption value and the ideal fuel consumption value.

Referring to fig. 16, a flowchart of an operation of calculating an actual fuel consumption value according to an embodiment of the present invention is shown.

If the vehicle has the fuel consumption value of hundred kilometers, the stored fuel consumption value of hundred kilometers can be used as the real-time fuel consumption value, and if the vehicle does not have the fuel consumption value of hundred kilometers, the fuel consumption value of hundred kilometers is supplemented and corrected to obtain the real-time fuel consumption value.

And S17, generating oil consumption analysis information by using the oil consumption deviation value.
