The data of the same starting position and the same end position are screened out to calculate the average power consumption during running, compared with all historical information, the vehicle information of the same starting position and the same end position has the same road conditions due to the fact that the distance traveled by the vehicle is the same when the average power consumption during running of the vehicle is calculated, and therefore the influence of different road conditions on the calculation result can be reduced by adopting the matched historical running end starting point information calculation, and accuracy is higher.
And S204, determining the average power consumption of the vehicle in a tri-linear interpolation mode according to the running speed information of the vehicle at the current acquisition time and the historical running data associated with the historical running ending and starting point information.

In practical application, because a statement of a trilinear interpolation algorithm is integrated in MATLAB, interpolation can be calculated through one instruction, so that only a simple MATLAB instruction is needed to calculate the running average power consumption of an interpolation point corresponding to an average speed and an average acceleration under the condition that a historical average speed, a historical average acceleration, a historical running average power consumption, an average speed and an average acceleration are known, which is the prior art, and is not described here, and certainly, the invention can be realized through other modes, and the invention is not limited by the embodiment.

Specifically, the historical ambient average temperature matched with the current temperature information is determined, the historical average speed, the historical average acceleration and the historical running average power consumption in the historical driving data corresponding to the historical ambient average temperature are determined, the historical average speed and the historical average acceleration in the multiple pieces of historical driving data corresponding to the historical driving data are calculated in a trilinear interpolation mode according to the average speed and the average acceleration of the vehicle at the current acquisition time, and the running average power consumption of the vehicle corresponding to the average speed and the average acceleration at the current acquisition time is obtained, wherein the trilinear interpolation calculation method adopted in the step is the same as that in the step S204.

S206, determining the current average power consumption in the current power consumption information according to the ratio of the power consumption of the vehicle to the running distance.
In the present embodiment, the consumed power may be specifically understood as the battery power consumed by the vehicle when the vehicle starts to drive to the current time or the current position.
Specifically, the consumed electric quantity may be acquired by sending the battery management system BMS to the vehicle control unit; the current average power consumption is calculated by comparing the vehicle power consumption with the travel distance, i.e., the current average power consumption is equal to the vehicle power consumption divided by the travel distance.
And S207, determining a current power consumption weighting coefficient in the current power consumption information according to the running distance and a preset power consumption weighting coefficient table.
In particular, the power consumption weighting factor table may be understood as a data table storing the distance traveled by the vehicle in the current driving cycle and the corresponding power consumption weighting factor.
Specifically, the travel distance and the power consumption weighting coefficient are correspondingly stored in the power consumption weighting coefficient table, and after the travel distance of the vehicle is determined, the data in the power consumption weighting coefficient table are interpolated in a linear interpolation mode to determine the current power consumption weighting coefficient corresponding to the travel distance.
Further, fig. 4 provides a flowchart for determining a current power consumption weighting coefficient in the vehicle remaining range determining method, where determining the current power consumption weighting coefficient in the current power consumption information according to the travel distance and a preset power consumption weighting coefficient table specifically includes the following steps:
and S2071, determining an interpolation interval and an interpolation point corresponding to the driving distance in the power consumption weighting coefficient table.
Specifically, an interpolation interval and an interpolation point corresponding to the running distance of the vehicle at the current acquisition time are determined according to the running distance stored in the power consumption weighting coefficient table. For example, table 1 provides a power consumption weighting factor table.
TABLE 1
And S2072, determining the power consumption weighting coefficient of the interpolation point according to the power consumption weighting coefficients corresponding to the travel distances of the upper limit and the lower limit of the interpolation interval.
And S2073, taking the power consumption weighting coefficient of the interpolation point as the current power consumption weighting coefficient.
For example, the determination process of the current power consumption weighting coefficient is illustrated, when the driving distance is 35km, the interpolation interval is determined to be [30-40], and the interpolation point is 35. The power consumption weighting coefficient corresponding to the interpolation interval lower limit of 30km is 0.7, the power consumption weighting coefficient corresponding to the interpolation interval lower limit of 40km is 0.6, and the power consumption weighting coefficient of the interpolation point is [ (35-30)/(40-30) ] (0.6-0.7) +0.7 is 0.65, so the current power consumption weighting coefficient is 0.65.
And S208, determining that the product of the average running power consumption and the current power consumption weighting coefficient in the current power consumption information is a first product.
S209, determining a difference value between 1 and the current power consumption weighting coefficient, and determining that the product of the difference value and the current average power consumption in the current power consumption information is a second product.
S210, determining a sum of the first product and the second product, and taking a ratio of the residual capacity of the vehicle to the sum as the remaining mileage.
In the present embodiment, the remaining amount of the vehicle may be specifically understood as the amount of electricity remaining in the battery of the electric vehicle at the current collection time.
Specifically, the remaining power of the vehicle may be obtained by sending the remaining power to the vehicle controller by the battery management system BMS; the remaining mileage value can be calculated by the formula:
range _ remaining is the remaining Range of the vehicle in km; battery _ energy is the residual capacity of the vehicle power Battery and has the unit of kWh;
is the current power consumption weighting coefficient without unit; EC (EC)historyThe average power consumption is the running average power consumption, and the unit is kWh/100 km; EC (EC)beforeIs the current average power consumption in kWh/100 km.
And after determining the residual electric quantity, the average running power consumption, the current power consumption weighting coefficient and the average running power consumption of the vehicle, substituting the residual electric quantity, the average running power consumption, the current power consumption weighting coefficient and the average running power consumption into a formula to calculate the residual mileage of the vehicle. Because the average power consumption during driving and the current average power consumption have different calculation influences on the remaining mileage of the vehicle, different proportions are allocated to the average power consumption during driving and the current average power consumption according to the influence of the average power consumption during driving and the current average power consumption on the remaining mileage, and the result of the remaining mileage obtained through calculation is more accurate.
And S211, when the ignition switch of the vehicle is monitored to be turned off, determining the total running distance and the total consumed electric quantity of the vehicle.
In the present embodiment, the total travel distance can be specifically understood as the total travel distance of the vehicle from the driving cycle of turning on the ignition switch, starting driving, and turning off the ignition switch; the total power consumption is understood in particular to mean the battery power consumed by the vehicle during a driving cycle.
Specifically, the total travel distance may be that the vehicle body stability control unit ESP sends to the vehicle control unit; the total consumed power may be transmitted to the vehicle control unit by the battery management system BMS. Detecting that the ignition switch of the vehicle is turned off means that the vehicle ends the current driving cycle, and information in the running process of the vehicle needs to be saved for updating the historical driving information table.
And S212, determining the historical average power consumption according to the ratio of the total consumed power and the total distance traveled.
And the average power consumption is the power consumption/distance, and the average power consumption of the historical driving is obtained by dividing the total consumed power by the total driving distance.
And S213, storing the historical running average power consumption and the vehicle running information as historical running data into a historical running information table to form an updated historical running information table.
In the present embodiment, the vehicle running information may be specifically understood as information generated during running of the vehicle, and may be a starting point position, an end point position, an average speed, a total running distance, an average acceleration, and an ambient average temperature of the vehicle.
Specifically, the calculated historical average power consumption of the running and the vehicle running information are stored as historical running data together and stored in a historical running information table so as to update the historical running information table. After the vehicle finishes one driving cycle each time, historical driving data is stored once, and the historical driving information table is updated once. Therefore, the driving history of each time is actively stored, the information can be ensured to be updated in time, and the prediction of the remaining mileage cannot be influenced because the information in the historical driving information table is too old.
The embodiment of the invention provides a method for determining remaining mileage of a vehicle, which comprises the steps of obtaining preset driving end starting point information of vehicle driving and the driving distance of the current acquisition moment; determining the average running power consumption of the vehicle based on the vehicle end-of-travel starting point information, and determining the current power consumption information of the vehicle at the current collection time based on the running distance; and determining the remaining mileage of the vehicle according to the average running power consumption and the current power consumption information. The average running power consumption and the current power consumption information of the vehicle are determined according to the running distance of the vehicle at the current acquisition moment and the starting point information of the end of running, so that the remaining mileage of the vehicle is determined, the problem that the actual remaining driving mileage of the vehicle cannot be accurately predicted in the driving process of the vehicle is solved, and the method is simple and easy to implement; the calculation range can be reduced and the calculation amount can be reduced by searching matched data in the historical driving information table, and the calculation error caused by the influence of the environment and the road can be reduced by primary screening, so that the accuracy of the remaining mileage prediction is improved; different proportions are set for the average power consumption during driving and the current average power consumption through the current power consumption weighting coefficient in the current power consumption information, and the accuracy of the calculation result of the remaining mileage is improved.
