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 for explaining the present invention, and is not considered as limiting the invention.
Detection method, the device of the electric vehicle remaining mileage proposed according to embodiments of the present invention are described with reference to the accompanying drawings
And the vehicle with it, the detection of the electric vehicle remaining mileage proposed according to embodiments of the present invention is described with reference to the accompanying drawings first
Method.
Fig. 2 is the flow chart of the detection method of the electric vehicle remaining mileage of one embodiment of the invention.
As shown in Fig. 2, detection method includes the following steps for the electric vehicle remaining mileage：
In step s 201, judge whether vehicle enters and preset operating mode.
It is understood that as shown in Figure 1, vehicle remaining mileage easy tos produce mutation at the time of operating mode changes,
To influence user experience, therefore, the embodiment of the present invention carries out the judgement of operating mode, the amendment being then mutated again first.
In one embodiment of the invention, default operating mode may include upward slope operating mode, descending operating mode, accelerating mode and subtract
Either vehicle enters anxious the case where accelerating or suddenly slowing down to the special circumstances such as fast operating mode etc., i.e. mountainous region, does not do specific limit herein
It is fixed.
It should be understood that vehicle easy tos produce instantaneous energy consumption at the ascents and descents moment, so as to cause in ascents and descents
At the time of vehicle remaining mileage generate mutation, wherein the calculation formula of the remaining mileage of vehicle can be：
To sum up, it can be obtained from the calculation formula of vehicle remaining mileage, when instantaneous energy consumption increases suddenly, the residue of vehicle
Mileage can reduce suddenly accordingly；And when the instantaneous energy consumption of vehicle reduces suddenly, the remaining mileage of vehicle can also increase suddenly,
And the mutation of this remaining mileage can bring puzzlement to user, reduce user experience.
For example, in vehicle driving up or when vehicle suddenly accelerates, increase since instantaneous energy consumption is very fast, vehicle is remaining
Mileage suddenly drops to 60KM from 100KM, and still, current working is special operation condition, only exists very short time, once it is restored to normal
When operating mode, vehicle remaining mileage can be restored to certain mileage such as 98KM at once again, and this mutation usually allows user's indigestion,
Reduce user experience；Similarly, in vehicle descending or when vehicle suddenly slows down, there are energy regenerating, the residue of vehicle at this time
Mileage also will appear of short duration increase, be then returned to a normal value, and the mutation of vehicle remaining mileage greatly reduces use
The usage experience at family.Therefore, the embodiment of the present invention can first judge whether vehicle enters special operation condition, with to vehicle remaining mileage
It is modified, remaining mileage is avoided to mutate, reduce user experience.
In step S202, if vehicle, which enters, presets operating mode, the remaining mileage of the previous moment of vehicle is obtained.
It is understood that vehicle generates mutation when entering default operating mode, due to instantaneous energy consumption at this moment,
And the embodiment of the present invention can be gone to correct this puzzlement for being mutated and taking to user by the remaining mileage of acquisition previous moment,
Promote the usage experience of user.
For example, in vehicle driving up, or when vehicle suddenly accelerates, increase since instantaneous energy consumption is very fast, vehicle is surplus
Remaining mileage suddenly drops to 60KM from 100KM, then can be raised to 98KM again, as a result it will be appreciated that, vehicle is at the time of going up a slope, such as
Current working when fruit maintains to go up a slope, the practical remaining mileage of vehicle is 60KM, and still, current working is special operation condition, is only deposited
In very short time, when being restored to nominal situation, vehicle remaining mileage can be restored to certain mileage such as 98KM at once again, cause
Generate unnecessary mutation.Therefore, the embodiment of the present invention can be by the remaining mileage of acquisition previous moment, such as 100KM, then
The remaining mileage at moment of going up a slope is modified on the basis of 100KM.
In vehicle descending, or when vehicle suddenly slows down, there are energy regenerating, vehicle remaining mileage prominent from 100KM at this time
120KM so is risen to, then can drop to 98KM again, as a result it will be appreciated that, vehicle is at the time of descending, if maintain descending
Current working, the practical remaining mileage of vehicle is 120KM, and still, current working is special operation condition, only exists very short time,
When being restored to nominal situation, vehicle remaining mileage can be restored to certain mileage such as 98KM at once again, and it is unnecessary to cause to generate
Mutation.Therefore, the embodiment of the present invention can pass through the remaining mileage of acquisition previous moment, such as 100KM, then 100KM's
On the basis of the remaining mileage at descending moment is modified.
Further, in one embodiment of the invention, according to the institute of the current electric quantity of power battery and previous moment
The instantaneous power consumption of place's operating mode obtains the remaining mileage of previous moment.
It is understood that when vehicle enters upward slope or descending operating mode, since there are instantaneous power consumption, the residues of vehicle
Larger fluctuation can occur for mileage, but the mode of vehicle detection vehicle remaining mileage does not change at this time, therefore can pass through this
When the instantaneous power consumption of the residing operating mode of electricity and previous moment that detected can obtain the remaining mileage of previous moment.It needs
It is noted that there are many kinds of the measurement methods of remaining mileage, it is not particularly limited herein.
Further, in one embodiment of the invention, the method for the embodiment of the present invention further includes：According to instantaneous power consumption
Obtain the power energy consumption and attachment energy consumption of electric vehicle；Obtain the current time of vehicle respectively according to power energy consumption and attachment energy consumption
Correspondence remaining mileage.
It is understood that different from the insensitivity that user influences starting, climb and fall, attachment energy consumption, especially
The use of the attachmentes such as air conditioner, the influence for remaining mileage be user it can be readily appreciated that and expect, therefore, the present invention
Embodiment removes attachment energy consumption and power energy consumption, handles its influence for remaining mileage respectively, user friendly to improve
The performance of degree and remaining mileage prediction.
For example, user is when using high pressure attachment, such as using air conditioner, and the use of air conditioner is for continuation of the journey
Mileage has an impact, and can reduce the remaining mileage of vehicle, and therefore, when user opens air conditioner, the embodiment of the present invention to remain
Remaining mileage mutates, for example, remaining mileage suddenly falls to 90KM from 100KM, it can be right to allow user to understand high pressure attachment
Remaining mileage generates large effect, to effectively improve the usage experience of user.Equally, when user closes air conditioner,
Remaining mileage of the embodiment of the present invention mutates, for example, remaining mileage sharp rises to 110KM from 100KM, to allow user
Large effect can be generated to remaining mileage by solving high pressure attachment, to effectively improve the usage experience of user.
In step S203, the remaining mileage of previous moment is modified according to the current vehicle speed of vehicle, to obtain vehicle
Current time remaining mileage.
It is understood that as shown in figure 3, the embodiment of the present invention by vehicle start, vehicle driving up, when vehicle descending
Remaining mileage do automatic amendment, come smooth power energy consumption caused by remaining mileage curve.The embodiment of the present invention passes through to residue
The automatic amendment of mileage improves the usage experience of user to effectively avoid the generation of catastrophe point.
For example, vehicle such as frequent start-stop, coastal city undulating topography wait the city parking lot scape under complex working conditions
Under vehicle, the embodiment of the present invention effectively avoids the detection of remaining mileage from mutating, carries by automatically being corrected to remaining mileage
High user experience degree of impression promotes brand texture.
For example, in vehicle driving up, the remaining mileage of vehicle is 100KM, and in vehicle driving up, it is instantaneous when due to going up a slope
The remaining mileage of the reason of energy consumption, vehicle will produce larger mutation, and the remaining mileage of vehicle is shown as 60KM at this time, still,
Current working is special operation condition, only exists very short time, and when being restored to nominal situation, vehicle remaining mileage again can be at once extensive
Certain mileage such as 98KM is arrived again, causes to generate unnecessary mutation.Therefore, the embodiment of the present invention passes through to being remained to previous moment
Remaining mileage is modified, to obtain the remaining mileage at the current time of vehicle, the embodiment of the present invention can in the following manner into
Row is corrected：
For example, first, the embodiment of the present invention carries out the detection of the gradient, in different range of grade, vehicle remaining mileage
Situation of change it is different, for example, in the section that range of grade is 0-30 °, the remaining mileage of vehicle will not mutate, because
This, in the range of the gradient is 0-30 °, without the amendment of remaining mileage, i.e. correction value can be 0.It is in range of grade
In 30 ° -45 ° of section, the remaining mileage of vehicle remaining mileage mutation such as vehicle is 60KM, and is once restored to normal work
When condition, vehicle remaining mileage can be restored to certain mileage such as 96KM at once again, then in the section that the gradient is 30 ° -45 °, pass through
The current vehicle speed of vehicle is modified the remaining mileage of previous moment, i.e., correction value is preset certain value or correction value
Can be adaptively adjusted according to current hill grade, as correction value be 4KM, or the gradient be 30 ° when, correction value 2KM, often
Increase by 5 ° of the gradient, then correction value increases 1KM, to carry out being adaptively adjusted according to the gradient, to obtain vehicle
The remaining mileage at current time, those skilled in the art can according to actual conditions to the corresponding correction value in specific gradient section into
Row setting, is not particularly limited herein.
Further, in one embodiment of the invention, the method for the embodiment of the present invention further includes：Detect the row of vehicle
Car state；If driving states are starting state, current time is obtained according to the remaining mileage stored when electricity under the last time
Remaining mileage.
It is understood that when vehicle start, than height of the energy consumption after step under unit operating range, because in residue
The predicted value of journey is negative correlation with energy consumption speed, and therefore, the remaining mileage of vehicle easy tos produce mutation at this moment, influences user's
Usage experience, and the embodiment of the present invention is by being modified catastrophe point, for example remaining mileage when last lower electricity is 90KM,
And when starting, since instantaneous energy consumption is relatively high, remaining mileage when may start is 80KM, and the embodiment of the present invention is then according to upper
Remaining mileage 90KM when principal, on this basis to start when remaining mileage be modified, such as when level land starts,
Remaining mileage when last lower electricity is kept, i.e. remaining mileage is still 90KM, and is detected when being poured on hill-start, then according to inspection
The different gradient measured, is corrected accordingly.
For example, remaining mileage when electric under the vehicle last time is 90KM, in the section that range of grade is 0-30 °,
When vehicle start, vehicle remaining mileage mutates, and when being restored to nominal situation, vehicle remaining mileage again can be at once extensive
Certain mileage is arrived again, if remaining mileage is 90KM, when starting in the range of the gradient is 0-30 °, according to electric under last vehicle
When remaining mileage be modified, at this point, remaining mileage such as 90KM when keeping electricity under last vehicle, i.e. correction value are 0.
In the section that range of grade is 30 ° -45 °, the surplus of current time is obtained by the remaining mileage stored when electricity under the vehicle last time
Remaining mileage, i.e. correction value, which are preset certain value or correction value, to be adaptively adjusted according to current hill grade, and vehicle exists
When this gradient section starts, vehicle remaining mileage mutation such as remaining mileage is 50KM, and when being restored to nominal situation,
Vehicle remaining mileage can be restored to certain mileage such as 86KM at once again, then at this point, according in the residue under last vehicle when electricity
Journey is modified, if correction value is 4KM.Or when the gradient is 30 °, correction value 2KM often increases by 5 ° of the gradient, then corrects
Value increases 1KM, so as to be adaptively adjusted according to the gradient.In addition, those skilled in the art can be according to actual conditions
It is configured, is not specifically limited herein.The remaining mileage when embodiment of the present invention is by vehicle launch is modified, to
The generation for effectively avoiding catastrophe point, greatly enhances the user experience.
It should be noted that the driving conditions of vehicle, including starting, it drives a vehicle, braking, 4 stages of parking.Ignore climb and fall
When gravity belt come additional effect, then need that maximum static friction force is overcome to do positive work when vehicle start, overcome in accelerator
Rolling friction couple square does positive work, and when braking does negative work by energy regenerating and force of sliding friction to vehicle reduces speed.It can be with
Find out, the instantaneous energy consumption highest of power of vehicle start, cause at this time remaining mileage be in a low spot, with instantaneous energy after starting
The reduction of consumption, as shown in Figure 1, remaining mileage curve shows ascendant trend instead.Vehicle is when going up a slope since it is desired that additional gram
Gravity acting is taken, under the premise of maintaining current vehicle speed, the instantaneous energy consumption of power increases；Because gravity makees just vehicle when descending
Work(, the instantaneous energy consumption of power reduce.But user is often not obvious the impression of climb and fall, reacts in remaining mileage curve
On, these are all the catastrophe points that do not expected.The embodiment of the present invention effectively avoids the generation of these catastrophe points by amendment, from
And it greatly enhances the user experience.
