The fuel economy evaluation method based on the driving environment can be applied to different scenes, and the fuel economy evaluation method based on the driving environment is further explained by combining four scenes.
The first scenario is: the driving environment request is a overtaking confirmation request; the driving environment information is overtaking confirmation information, wherein the overtaking confirmation information comprises information whether the vehicle is in an overtaking state currently; on the basis, when the fuel economy score is smaller than the first preset threshold value, whether a steering lamp of the vehicle is in an on state or not is judged; and when the steering lamp of the vehicle is in an on state, sending the overtaking confirmation request to a server. Judging whether the vehicle is in a overtaking state currently or not according to the received overtaking confirmation information; and when the vehicle is in the overtaking state at present, sending out prompt information to prompt a driver that the current driving state does not meet the fuel economy requirement.
The second scenario is: the driving environment request is a overtaking confirmation request; the driving environment information is fuel economy estimation scores; on the basis, when the fuel economy score is smaller than the first preset threshold value, whether a steering lamp of the vehicle is in an on state or not is judged; and when the steering lamp of the vehicle is in an on state, sending the overtaking confirmation request to a server. Judging whether the fuel economy estimation score is smaller than a second preset threshold value or not; and when the fuel economy estimation score is smaller than the second preset threshold value, sending out prompt information to prompt a driver that the current driving state does not meet the fuel economy requirement.
The third scenario is: the driving environment information is a fuel economy evaluation request; the driving environment information is the distance between a traffic light and the vehicle and the light change time of the traffic light; on the basis, whether the fuel economy score is smaller than the first preset threshold value is a reasonable condition or not is judged according to the distance between the traffic light and the vehicle and the light changing time of the traffic light; and when the fuel economy score is smaller than the first preset threshold value and does not belong to a reasonable condition, sending out prompt information to prompt a driver that the current driving state does not meet the fuel economy requirement.

Therefore, when the fuel economy score of the first vehicle is not in accordance with the preset condition, whether the driver is reminded or not is judged by determining the current environment state of the first vehicle, and when the vehicle is in an abnormal driving state (such as overtaking, a red light immediately ahead, congestion of a road section where the vehicle is located and the like), the driver is not reminded of poor fuel economy, so that unnecessary trouble is avoided being caused to the driver.
Fig. 2 is a schematic flow chart of a driving environment-based fuel economy evaluation method according to a second embodiment of the present invention, in which the driving environment-based fuel economy evaluation method is applied to a server, as shown in fig. 2, the driving environment-based fuel economy evaluation method includes the following steps:
step 201: the method comprises the steps of receiving a driving environment request sent by a vehicle, wherein the driving environment request comprises position information and speed information of the vehicle.

Corresponding to a fourth scenario: the driving environment request is a fuel economy evaluation request; determining the number and the speed information of other vehicles in a preset range around the vehicle according to the position information and the speed information of the vehicle, and determining whether a road section where the vehicle is currently located is in a congestion state; and transmitting congestion state information to the vehicle.
The driving environment-based fuel economy evaluation method of the present invention will be further described with reference to specific embodiments, which are described by way of interaction between a driving environment-based fuel economy evaluation device and a server.
As shown in fig. 3, in the present embodiment, the first vehicle may include a Global Positioning System (GPS) module 31, an On-Board Diagnostic (OBD) module 32, a fuel economy evaluation module 33, and a prompt module 34. The module is integrated in a fuel economy evaluation device based on the driving environment; the GPS module 31 is used for determining the current position information of the first vehicle; the OBD module 32 is configured to determine current driving information of the first vehicle, such as a vehicle speed and turn signal information; the fuel economy evaluation module 33 is used for determining whether a driver needs to be reminded when the current fuel economy score of the first vehicle does not meet the requirement; the prompting module 34 may be a display screen, a speaker, etc. for prompting the driver.
The fuel economy evaluation module of the first vehicle is in wireless connection with the background server to achieve communication, the background server can also achieve communication with other vehicles, and the other vehicles can comprise a GPS module 31 and an OBD module 32 and are used for determining position information and driving information of the other vehicles.
Referring to fig. 4, a fuel economy evaluation method based on a driving environment according to a third embodiment of the present invention includes the steps of:
Specifically, the motion state information of the vehicle may include a vehicle speed, an engine speed, gear information, real-time oil consumption, and the like, and the motion state information may be acquired by the OBD module.
The method for determining the current fuel economy grade or fuel economy grade of the vehicle through the motion state information of the vehicle belongs to the prior art, and is not repeated in the invention. The fuel economy grade and the fuel economy grade have the same essence, and the fuel economy evaluation based on the driving environment is carried out according to the fuel economy grade, wherein the higher the fuel economy grade is, the better the fuel economy corresponding to the vehicle is, and the lower the fuel economy grade is, the worse the fuel economy corresponding to the vehicle is.
The first preset threshold is a general standard of vehicle fuel economy, when the fuel economy score is smaller than the first preset threshold, the first vehicle is not required to meet the fuel economy requirement currently, and when the fuel economy score is larger than the first preset threshold, the first vehicle is required to meet the fuel economy requirement currently.
The first preset threshold may be determined by a drive test, or may be determined according to other methods. The first preset threshold value can also be adjusted according to information such as the vehicle model, the engine performance, the specific use state of the vehicle and the like.
If the fuel economy score is smaller than a first preset threshold value, judging whether a current steering lamp of the vehicle is turned on: if the turn signal is on, indicating that the first vehicle may be in a cut-in state, continuing to the following steps; if the steering lamp is not turned on, the first vehicle is not in the overtaking state currently, and at the moment, prompt information can be sent to the driver to prompt that the current motion state of the driver does not meet the fuel economy standard.
And step 404, if the turn signal is in an on state, the fuel economy evaluation module of the first vehicle sends a overtaking confirmation request to the server, wherein the overtaking confirmation request comprises the position information and the speed information of the vehicle.
Wherein the location information of the vehicle may be determined by the GPS module and the speed information may be determined by the OBD module. Because whether the turn signal of the vehicle is turned on does not completely correspond to whether the vehicle is in the overtaking state, after the turn signal is judged to be turned on, the fuel economy evaluation module of the first vehicle also sends an overtaking confirmation request to the server, and the overtaking confirmation request is used for requesting the server to confirm whether the first vehicle is in the overtaking state currently.
Specifically, the preset range may be determined according to actual needs, and in the present invention, the preset range may be a range of 200 meters around the first vehicle. The location information of the other vehicle may be determined by the other vehicle's GPS module and OBD module.
And step 406, the server determines whether the first vehicle is in a overtaking state or not according to the position information and the speed information of the first vehicle and the position information and the speed information of other vehicles, and sends overtaking confirmation information to a fuel economy evaluation module of the first vehicle.
Specifically, it may be considered that the first vehicle is in the overtaking state when the position of the other vehicle is initially in front of the first vehicle, the interval between the other vehicle and the first vehicle gradually decreases with the passage of time, and after a period of time elapses, the other vehicle is located behind the first vehicle, and the speed of the other vehicle is always not greater than the speed of the first vehicle, according to the position information of the first vehicle and the other vehicle.
The overtaking confirmation information includes information about whether the first vehicle is currently in an overtaking state.
According to the scheme, when the fuel economy score of the first vehicle does not meet the preset condition, the fuel economy evaluation module of the first vehicle judges whether a steering lamp is turned on at present or not, if the steering lamp is turned on, the server is requested to determine whether the first vehicle is in the overtaking state or not according to the position information and the speed information of other vehicles within the preset range, when the first vehicle is in the overtaking state, the driver is not reminded of poor fuel economy, and when the first vehicle is not in the overtaking state, the driver is reminded. This scheme can be when the driver overtakes, not carry out the relatively poor warning of fuel economy to the driver, avoid causing unnecessary trouble for the driver.
Referring to fig. 5, a fuel economy evaluation method based on a driving environment according to a fourth embodiment of the present invention includes the steps of:
And step 504, if the steering lamp is in an on state, the fuel economy evaluation module of the first vehicle sends a overtaking confirmation request to the server, wherein the overtaking confirmation request comprises the position information and the speed information of the vehicle.
Specifically, the implementation principle of steps 501 to 504 is similar to that of steps 401 to 404 in the previous scheme, and is not described here again.
And 505, the server determines the position information and the speed information of a second vehicle positioned in front of the first vehicle and a third vehicle which is positioned on the left side of the first vehicle and drives in head-on according to the position information of the vehicles.
Specifically, the server may acquire position information of other vehicles around the first vehicle, and determine vehicles driving ahead and left of the first vehicle according to the position of the first vehicle and the positions of the other vehicles, and fig. 6 shows a schematic position diagram of the first vehicle, the second vehicle, and the third vehicle.
Specifically, the current speeds of the first vehicle, the second vehicle and the third vehicle are s1, s2 and s3 respectively, the distance between the first vehicle and the third vehicle is l1, the distance between the first vehicle and the second vehicle is l2, the overtaking is completed after the time t2 passes by the speed s1 'assuming that the time t1 passes by the first vehicle is increased from the current initial speed s1 to the maximum speed s 1', and the speeds of the second vehicle and the third vehicle are always kept unchanged at t1 and t2, so that the speeds of the first vehicle, the second vehicle and the third vehicle meet the following conditions:
wherein k is a safe distance between two vehicles and can be set according to actual needs. the value of t1 may be predetermined, for example, during a cut-in, it typically takes a few seconds to increase from the initial speed to the maximum speed, and thus t1 may be in the range of 2-5 seconds. t1, the maximum speed s 1' of the first vehicle during the passing, the passing time t1+ t2 and the acceleration a1 required for passing can be determined according to equation (1):
t1+t2＝(l1-l2-k)/(s2+s3) (2)
according to the formulas (2), (3) and (4), the overtaking information such as the acceleration value, the acceleration time, the maximum speed, the overtaking required time and the like of the first vehicle in the overtaking process can be estimated according to the current position information and the current speed information of the vehicle, and the fuel economy score of the first vehicle in the overtaking process is estimated according to the estimated overtaking information to obtain the estimated fuel economy score.
Specifically, a drive test may be performed on a vehicle of a model corresponding to the first vehicle in advance, that is, the fuel economy score corresponding to the vehicle of the model in different running states, such as different vehicle speeds and different accelerations, may be tested on a road, and the corresponding relationship between the relevant running state and the fuel economy score may be recorded. In this step, the corresponding fuel economy estimation score can be determined according to the estimated maximum speed, acceleration and other information of the first vehicle in the overtaking process.
And step 507, the server sends the fuel economy estimation score of the first vehicle in the overtaking process to a fuel economy evaluation module of the first vehicle.
In this step, the second preset threshold may be set according to actual needs, but the second preset threshold should be smaller than the first preset threshold, that is, the requirement for fuel consumption during overtaking is lower than the requirement for fuel consumption during normal driving. The driver may not be alerted as long as the estimated fuel economy score is greater than a second predetermined threshold (although possibly not greater than the first predetermined threshold). If the fuel economy estimation score and the second preset threshold value are not reached, the fact that the oil consumption of the first vehicle in the overtaking process does not meet the fuel economy requirement according to the estimated overtaking information is shown, the driver can be prompted at the moment, and the driver can terminate the overtaking action according to the prompt conveniently.
According to the scheme, the acceleration, the maximum speed and the like of the first vehicle in the overtaking process are estimated according to the position information and the speed information of the first vehicle and the position information and the speed information of the first vehicle in front of and on the left of the first vehicle, the fuel economy score of the vehicle is estimated according to the acceleration, the maximum speed and the like, whether the fuel economy estimation score in the overtaking process meets the preset condition is judged, if the fuel economy estimation score meets the preset condition, the prompt is not given to a driver, when the condition is not met, the driver is reminded, and the driver can conveniently know the problem that the fuel consumption is too large due to overtaking in the existing environment in time.
Referring to fig. 7, a fuel economy evaluation method based on a driving environment according to a fifth embodiment of the present invention includes the steps of:
step 701, a fuel economy evaluation module of the first vehicle determines a current fuel economy score of the vehicle according to the motion state information of the vehicle.
And 703, if the fuel economy is smaller than a first preset threshold, the fuel economy evaluation module of the first vehicle sends a fuel economy evaluation request to a server, wherein the fuel economy evaluation request carries the position information and the speed information of the first vehicle.
The method can be realized through the following specific steps:
step 7051, determining whether the distance between the first vehicle and the traffic light is less than a preset distance threshold. If yes, executing step 7052, otherwise, reminding the driver that the current driving does not meet the fuel economy requirement.
Step 7052, determining a difference value between the last light changing time and the current time and a difference value between the next light changing time and the current light changing time according to the last light changing time and the next light changing time of the traffic lights.
The lamp changing in the scheme refers to changing a red lamp into a green lamp or changing a green lamp into a red lamp.
Step 7053, determining whether at least one of the two difference values is smaller than a preset time threshold: if so, not reminding the driver; if not, reminding the driver that the current driving does not meet the fuel economy requirement.
Specifically, if the difference between the last light changing time and the current time is smaller than the preset time threshold, it indicates that the driver may need to brake suddenly at the moment, and if the difference between the next light changing time and the current time is smaller than the preset time threshold, it indicates that the driver may need to accelerate to rush away at the moment.
Or, as long as the current fuel economy score is not too low, the driver need not be alerted; if the fuel economy score is too low, the driver can be alerted even in the event of a light change.
In the scheme, when the current fuel economy score is low, whether the driver is reminded or not is determined through the traffic light information, and the fuel economy evaluation can be carried out more comprehensively.
Referring to fig. 8, a fuel economy evaluation method based on a driving environment according to a sixth embodiment of the present invention includes the steps of:
And 803, if the fuel economy is smaller than the first preset threshold, the fuel economy evaluation module of the first vehicle sends a fuel economy evaluation request to a server, wherein the fuel economy evaluation request carries the position information and the speed information of the first vehicle.
Wherein the preset range can be determined according to actual needs. Preferably, the road section where the first vehicle is currently located may be determined according to the position information of the first vehicle, and the number of vehicles on the road section and the speed information of each vehicle are acquired and obtained.
Specifically, when the number of vehicles on the road section is greater than a certain threshold value and the average speed of the vehicles on the road section is less than a certain threshold value, the road section can be considered to be in a congestion state, and if the road section is in the congestion state, the fuel economy score in the driving process is inevitably lower than the fuel economy score in the normal driving process, so that additional reminding of a driver is not needed.
In the scheme, when the current fuel economy score is low, whether the driver is reminded or not is determined according to the congestion condition of the road section where the first vehicle is located, and the fuel economy can be further comprehensively evaluated.
