Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
The electric energy consumption calculation method of vehicle drive system according to an embodiment of the present invention is described with reference to the accompanying drawings.
Fig. 2 is the flow chart of the electric energy consumption calculation method of vehicle drive system according to an embodiment of the present invention, such as Fig. 2 institute
Show, which includes:
S1 calculates the instantaneous power of vehicle drive system according to the motor speed of driver's requested torque and vehicle.
Specifically, full-vehicle control module calculates current driver's request according to input signals such as throttle, the brakes of driver
Torque T, motor control module provide motor speed N, are illustrated in figure 3 vehicle drive train according to an embodiment of the invention
The electric energy consumption calculating process schematic diagram of system, computing device can calculate the wink for working as front drive system according to formula P=T*N/9550
When power.
S2, according to instantaneous power and mileage unit of account mileage electric energy consumption.
Wherein, mileage can be obtained directly from instrument record or obtain vehicle row by motor speed calculating
The distance sailed.It is illustrated in figure 4 the calculating process schematic diagram of mileage travelled according to an embodiment of the invention, by motor control
Molding block provides motor speed, and vehicle obtains vehicle speed by the conversion of revolving speed calculation formula, then carries out time product to speed
Separately win to obtain mileage travelled, can take 1 kilometer or other as mileage.
Specifically, as shown in figure 3, carrying out integral calculation to the instantaneous power of acquisition, when detecting the complete unit of vehicle driving
At such as 1 kilometer of mileage travelled, integral obtains 1 kilometer of electric energy consumption using as unit mileage electric energy consumption to record at this time.
S3, the unit mileage electric energy consumption of bulk registration preset quantity is to obtain default mileage total energy consumption.
Specifically, instantaneous power integrate-dump is regained into instantaneous power simultaneously in unit mileage electric energy consumption of record
It is integrated, successively obtains the unit mileage electric energy consumption of preset group, and then calculate the energy of the unit mileage electric energy consumption of preset quantity
Summation is consumed using as default mileage total energy consumption, such as shown in Fig. 3, obtains accumulative 40 kilometers of total energy consumption.
The electric energy consumption calculation method of the vehicle drive system of the embodiment of the present invention, is counted according to the relevant parameter of drive system

Consumption obtains the total kilometrage that vehicle can travel, and then the difference of total kilometrage and the total kilometres travelled is current surplus
Current residual mileage can also be supplied to driver by display screen or instrument by remaining mileage, facilitated planning stroke or carried out row
Journey plan.
Alternatively, can judge the driving habit of driver according to default mileage total energy consumption.Specifically, different drivers drives
It is different to sail habit, for example, some drivers like the traveling that high speed stimulates, and some drivers then like slow under identical operating condition
Slow steady traveling, the electric energy consumption of vehicle drive system is different as a result, can recorde different driver's driving habits and right
The default mileage total energy consumption answered, therefore, it is possible to the driving habit of driver be judged according to default mileage total energy consumption, for vehicle number
According to statistics be of great significance with the improvement to drive system.
Alternatively, drive parameter can be adjusted according to default mileage total energy consumption to obtain the consumption of the optimal electrical power under current working.
Specifically, when carrying out the control of optimal energy consumption, change drive parameter under current working and for example adjust accelerator open degree or adjusting
Motor speed etc., the default mileage total energy consumption of estimation also will determine wherein the smallest default mileage total energy consumption with variation, then when
Electric energy consumption can be reduced by consuming corresponding drive parameter operation under preceding operating condition with the optimal electrical power.
Compared in the related technology by the consumption of battery capacity come in a manner of estimating electric energy consumption using having limitation, can only
For the estimation of new energy vehicle remaining mileage, the calculating of the embodiment of the present invention obtains electric energy consumption, the pure drive based on acquisition
The electric energy consumption of dynamic system, may be implemented more function relevant to drive system, such as can obtain current residual mileage, side
Just stroke plan also may determine that driver's driving habit and carry out electric energy consumption optimum control, and application range is more extensive.
