In this situation, we will discuss about driving cycle and its application with the vehicle.
Any vehicle, the characteristics of vehicle is need to decide before proceeding for the manufacturing
project on any vehicle, either it is electrical or ICBC.
First of all, we need to decide which type of vehicle we are going to working on.
That means the two wheeler, three wheeler, four wheeler motorcycle car truck.
That means its application.
So that what we need to decide and then after we need to decide the vehicle driving pattern, that means
vehicle is going to run mostly and which type of road condition it is also depend upon the traffic condition,
urban, rural and highway driving cycle and this driving pattern.
So there's two important things we need to decide before anything type of vehicle on its application
and its.
Driving that and so it is going to run on City Highway and Roura, so depending upon the different driving
pattern, is wearing white.
So we are going to different driving cycle after that.
So first, keep in mind, whatever your vehicle type and its application and how purposefully and which
particular road condition for which road condition it is.
So if we do find the driving cycle, a driving cycle is a series of data points representing speed of
vehicle versus time.
So you have a lot of paperwork of the time that speed is in kilometer per hour and time within seconds.
So to consider the driving cycle, it represents the particular road condition and we can say that in
the road.
So to understand driving cycle, you need to image any.
Dewpoint.
Of location in your mind that you're aware about, so image any 15 to 20 kilometer of any distance,
any road either in urban and city condition or anything else.
So I am considering the one city road that located in the end about Gujrat, that is from the visual
circle to the satellite.
So if I consider the one particular road and I want to map this road in form of our vehicle speed and
time so I can see the vehicle is accelerating at a certain speed, it is reaching at top speed and reducing
support.
The traffic condition is such that there is the traffic signal.
We need to we need stop time and again, speed is increasing and now we are having the higher speed
or the rear for the more time.
Speed is remaining constant at the higher against up time.
So this kind of a pattern we will have for our selected road condition or selected location.
So this pattern is called the driving cycle.
So I why that is the different.
And according to the road condition and traffic density, the driving cycle side one standard and specific
data that represent the speed of vehicle over this time and what they use, this standard pattern we
can use to standardize the efficiency and CO2 emission of the vehicle.
So I hope you understand what is the driving factor in terms of definition and its use.
Now we will see how we can use the driving cycle.
So it may be different for the different location and different parts of consideration, according to
a city and according to region.
But when we standardize the driving cycle, then we can use it for the various purpose, we can call
it the driving cycle, so that same driving cycle can be used for 15 purposes when we standardize driving
cycle, basically represent to the driving cycle, are used to reduce the expense of en route date and
time of testing.
It brings the road to the test lab in India and other countries will use the dynamo meter set up to
test the vehicle for type test and its efficiency measurement or some country.
Also use the computer simulation for predicting the performance of the vehicle based on driving test
driving cycle and represent the road condition.
And this dying pattern at this down cycle is applied to the vehicle model or actual vehicle in the laboratory.
So we do not require to test the vehicle en route.
So this same pattern can standardize and that can be supplied to the test vehicle accordingly with the
anemometer type assembly or the computer simulation.
The W.A. procedure, the world harmonized light vehicle procedure, so this light duty vehicle test
procedure is a global standard for determining the level of pollutant, CO2 emission and fuel consumption
of traditional and hybrid cars, as well as the range of fully electric cars.
But this is the latest thing that we are going to discuss.
Has so many old driving cycles are also there in the past.
What is the reality of it?
The standard driving cycle?
We can say that the driving cycle, categorizing three classes, class one or two and class three plus
one is the driving cycle used for testing of the low power vehicle with the power weight ratio less
than equal to 22.
We will discuss about the power weight ratio electron also.
But let's discuss.
Let me clear the power weight you are.
Weight ratio is the ratio of vehicle power.
That is mechanical power.
If we call it the one body of mass having the weight and its inertia then to go to fulfill the certain
task of the power.
So the power of the vehicle, that is a mechanical input power required to achieve the performance of
that performance in terms of maximum speed in acceleration.
If we want the higher max speed or the higher resolution, our requirement will be higher and divided
by the weight weight of the vehicle.
For lack of simplicity.
Let's consider that the example of bicycle and Wilgie consider the weight of both bicycle and weighted
with the rider is almost seems if because of the same weight of bicycle and wheelchair.
But if we consider its performance requirement to make the speed of bicycle is higher than the requirement
of the wheelchair acceleration requirement, it is also slightly higher in case of bicycle than the
wheelchair.
So competitively power required for the wheelchair application is less and required for the bicycle
is more than twice.
The body weight ratio of bicycle will be more than bodyweight.
They shafter.
We'll check both having the same bet.
This is just one example.
So you've got an idea about the issue just now and don't be confused about it, because it is really
not relating to the last two weeks with the 22 in between twenty to thirty four to less than thirty
four and greater than 22 is the power weight ratio will require the pattern of Class two and Class three
driving cycle pattern is used for high powered vehicle with the borrower traceability then thirty four.
If we look at the typical borrower ratio, most common cars have nowadays power weight ratio.
Forty two hundred.
What but so belong to the class three, so.
For the trucks and buses and power, weight ratio is less because weight is much higher than the car,
but not the required power is increased with compared to weight, so.
Vans and buses and belong to two, but if you go to truck and two wheelers, that also and the power
weight ratio less than belong to plus one.
So this class one, class two and three represent a particular standard driving cycle.
Let's look at one by one, starting from the class three, because it is for the car.
OK, this is the standard driving cycle that represented by the W.L. typically cycle class three.
So this is the series of data.
You can also take this data.
You can have such.
You can also have to fight to find data with respect to time.
You can see that at the top three are the actual speed that the average speed.
So everything can be calculated, total duration in terms of time, total duration in terms of distance
is also then stop duration, average speed with the stop duration, average speed calculation without
the duration.
So all calculation and also the area and this driving pattern, it's called the cycle plus three need
to apply to the last three vehicle.
Then Outweight ratio is better than thirty four for the car and this driving pattern.
So you can also say it's divided in four or five.
This is the initially low speed then medium speed and high speed and extra high speed.
But it is still remaining less than the 150 kilometers but at speed.
This is the last three driving cycle.
Some country use the miles per hour, that is a simple conversion, one kilometer per hour is equal
to zero point six to one three seven miles per hour.
This represented glass, too, you can see at maximum speed is reduced, it is less than 90 kilometres
per hour and there is only three parts low, medium and high speed.
This is to take the last two vehicle arbitration, less than thirty four and greater than 20 to.
Last one driving cycle, you can see spirits for the religious left in Santa Fe, around 60 kilometers
per hour is only maximum speed for taking this.
So you can use this data if you want to work on the driving cycle and it's better.
Now, look at the region of the world down cycle.
Different countries are using the new European driving cycle and it is a driving cycle.
Last updated in 1997 is also referred to as MBG Cycle Motor Vehicle Emison Group.
So this is the older version.
And what we discussed is W.L. Tippee is the latest version of driving cycle we are using from 1st September
2019.
All the light light duty vehicles that are to be registered in the European countries must comply with
the W.L. standard instead of NFL and else.
So European countries now use the W.L. since September 2000 19 for the distinct end of the vehicle.
The federal procedure, commonly known as the FPP seventy five for the safety driving cycle, are a
series of test defined by the US Environmental Protection Agency to measure emission and fuel economy
of passenger cars, including light trucks and heavy duty vehicles.
For the US, that is the standard driving cycle.
It's called the FPP seventy five.
There are a number of old driving cycle and patterns used by the different countries you can subject
on.
But what is the latest into W.L. topic that we discussed?
If someone wants to do the extensive research in the area of the driving cycle, that is the scope of
two things.
The first is driving cycle design.
So you can search and you can work on the how could be the end of driving cycle.
And also the second thing is how to predict the driving cycle, because you will find a number of literature
also or the prediction of driving psychology, because nowadays things are changing a lot and day by
day and we can predict the future.
Changing the road condition into a population density of cities in urban areas and highways.
Maximum speed capacities are increasing in decades so that all can be considered.
And driving cycle prediction for the future is also one area of research.
So this is not the more technical things, but because we are discussing the fundamental of electric
vehicle engine and also all the engineering students are all the tools, those who are willing to do
their contribution in the area of electric vehicle engineering or the automobile or the vehicle engineering
that can start the research work in the particular area.
One can also specify the driving cycle design or the new driving cycle, particularly for the application
and particularly for also future prediction of the driving cycle, particularly for the electrical vehicle
applications possible.
Because previous, if you consider the previous all you specified driving cycle, then they were limited
due to make the maximum speed and acceleration were considered according to the electrical vehicle,
during the time.
And it was emitted and I would compare two I see with those less.
So it's happening.
I shared a few research, few resources that resources can be used if someone want to mainly focus on
the driving cycle and it's do not require this to go to these resources.
But if you particularly want to know more about driving sika, you can report the resources that I have
here that the European driving cyclists call the AC 15 European urban driving cycle and European urban
cycle for the low power vehicle.
So I have shared the data point for the driving cycle and the link from where you can get better and
that European driving cycle.
I also shared the link for the one reference book of driving cycle for using the measurement of road
vehicle emission.
It will also help if someone was interested in knowing more about the pricing cycle.
Then old USA used the federal government drying cycle and federal highway driving cycle.
You can also search for this and you'll find easily they actually 48 and actually 72 driving cycle that
is in the USA.
You specifically ring cycle, you can find in as a two to seven, Athie.
Society of Automotive Engineers to 270 as the Ford driving cycle to two seven, eight, A, B, C and
D warehouse two to seven Acey is used specifically for the electrical vehicle in Japan and point fifteen
more driving cycle is used for the electrical vehicle.
Although it is the very old driving cycle later has this modification.
And two two seven eight.
I proposed in a 1970.
So you have you may have the idea what kinds of different specifications required for the electrical
break down Sika.
For India Type II, the type one test that used for dissaving vehicle Albon driving cycle, an extra
driving cycle parents are given in this document.
It is data collected from the area for the India and you must visit the area website, Automotive Research
Association of India for further information about the testing and its procedures.
