Calculating driver behaviour (eco-driving)

Topic: Calculating driver behaviour (eco-driving)

Now days CANbus is on many vehicles from machines to truck and some kind of evaluation of drivers behaviour is must have.

So my question to your help was :
"Can you tell me the best way to calculate percentage of various sensore values for example.

I want to calculate and put in report:
-(I have RPM sensore)percentage of "green" RPM ,say from 1000-1500 rpm .So how may green RPM in all RPM are done?
-percentage of KM driven from 80-85 Km
-(i have gas pedal sensore)percetage of driven km with no gas pedal ?how many km?
-driven km with brakeing(have brake sensore)
-driven km with retarder(have retarder sensore)
-driven km with tempomat in percentage(have temop.sensore)
......

Best regards"

Answer is that it cant be done in percetages .Only values can be gathered.

So in att I am going to put a doc how Mercedes has done evaluation on drivers .Similar option for Wialon has to be done.

Re: Calculating driver behaviour (eco-driving)

we have all that already working dont try to do on percentages do them by counts and you can creat your limits on each of the sensor then by creating a notification you can count the nuber of times

Re: Calculating driver behaviour (eco-driving)

Hi

I think this could be a great addition to wialon if a real eco driving system and ranking is implemented!
Real eco driving is taking not only information from accelerator sensor but from canbus information and drivers can be ranked by their driving behavior.
I am attaching a picture how it can be displayed.Percentage calculations has to be made and special report I think

Calculating driver behaviour (eco-driving)

Re: Calculating driver behaviour (eco-driving)

For example:
Rating by fuel consumption is based on the driving technique, which saves the most fuel. Rating is done by drivers or vehicles with lowest WF100 (Wasted fuel per 100 km) parameter.


WF100 = WF * 100 / Distance;

WF = WFIT +WFCC + WFRPM  + WFBRK;


WF – Wasted fuel;

WFIT – Wasted fuel, counted from idle time parameter; WFCC – Wasted fuel, counted from Cruise control usage; WFRPM- Wasted fuel, counted from RPM not in green band;
WFBRK – Wasted fuel, counted form Extreme and Harsh braking;


WFIT = (Current fuel consumptions liters / hour) x (Idling time(s) / 3600).


CCtime = (Time when CC could be turned on - Time when CC was turned on, when it could be);

WFCC = (CCtime (s) / 3600) x Average fuel consumption (liters/hour) x 0,05 (5 % of fuel consumption could have been saved if CC would be turned on).


WFRPM = (RPM in red band (s) / 3600) x Average fuel consumption (liters/hour) x 0,37 (37 percetn of fuel consumption is because of RPM in red band. Fuel consumption rises by 60 % , when in red band).
Used fuel per 10 km = Fuel used * 10 / Distance (km);

WFBRK = (Extreme braking events + Harsh braking events) * 10 / Distance (km) x Used fuel per 10 km x 0,26 (26 percent of fuel used in 10 km is because of braking events (each event for 10 km increases fuel by 35 %))

Rating by safety is based on the driving technique, which is the safest.

-    Over speeding (%) – 0,5 points for each 1 % ;

-    Extreme braking events (events/100 km) – 1 point for every event;

-    Harsh braking events (events/100 km) – 0,5 point for every event;

-    Harsh acceleration events (events/100 km) – 0,5 point for every event.

Re: Calculating driver behaviour (eco-driving)

aahero, Wialon already support such reports with some hardware capable of measuring driver actions. Visit our booth on Cebit, at that moment we should have more information and results.

Re: Calculating driver behaviour (eco-driving)

What was the result of this as this is of interest for me as well. The ability to be able to show drivers ranked by an eco driving criteria would be a great way of seeing who are costing the company the most amount of money.

BTW I can't see the attachment that was mentioned in the firts post.

Re: Calculating driver behaviour (eco-driving)

aahero, calculations and rate assignments for trips are done by terminal (hardware). It's like fuel sensor, too much data to be analized for GPRS connections.

I think that this would be a spectacular feature to have a display that the customer can pull up and see the rating for any vehicle in the fleet or a report of the best and worst drivers

What ever the result of this is harsh cornering should be a mandatory parameter capture as this is how to detect swerving behaviour as wellas going into a corner to harsh with a load. Differentiation needs to be made between empty and loaded vehicles.

sure. but not sure that every vehicle has an apporopriate sensor to detect if it's loaded or not.

Re: Calculating driver behaviour (eco-driving)

a sensor is not needed as you can do this based on operational aspects. If the vehicle is leaving a ware house or terminal you can assume it is loaded. After it leaves a customer geofence you can assume he has unloaded. So the monitoring parameteres for the first part of the trip, when he is under load, are different from the return journey when he is unloaded.

Fuel consumption is also affected as he will use more fuel under load than in an unloaded state.

Easier if they have a load sensor but it can be done manually.

Re: Calculating driver behaviour (eco-driving)

I doubt that we can consider those operational assumption as a basis for different calculations. And the app would hardly be able to assume loaded/not the way you do.

Re: Calculating driver behaviour (eco-driving)

In the application it could be a parameter that could be set on a trip to indicate if the loaded entries would be used for the consumption calculation.

Re: Calculating driver behaviour (eco-driving)

Eco-driving feature is in the final testing stage.

From what I seeing is all the requested features in this thread can be implemented with our trip ranking solution.

The only thing is that we counting trips and penalties for trips. E.g. we skipping from analysis all data between trips. Not suitable for construction equipment. But theere is no drving quality rank by itself in stationary units )

Please once you have the Beta we can test , we already have a solution that works with Atrack , it would be good to compare...

aressun, I can setup testing for you. For this you need to create dedicated account and provide to its user normal (edit) access to vehicles you wonna test eco driving on. And send me this information by e-mail.

Re: Calculating driver behaviour (eco-driving)

EcoDriving is now avaible for usage in Wialon.

To setup eco-driving settings please use unit properties.

The result can be visualized in reports (special eco-table and new column for other tables) or by EcoDriving application.

Full list of already natively supported devices by firmware and protocol is avaible here and we are open to add this feature to all other trackes, just contact us at hw@gurtam.com. All other devices are supported in compatible mode, this means, we calculate acceleration between two points by GPS coordinates and its really depend on messages sending interval.

Re: Calculating driver behaviour (eco-driving)

Sample configuration (avaible through import WLP) that you can start from setting up EcoDriving options for unit attached.
The configuration itself is for powerfull vehicle equipped with BCE tracker with eco-driving feature supported in firmware.
