Green Driving

Using a special GPS device equipped with 3G sensors, the Ecofleet system can monitor the driver´s behavior on the road. It tracks down sudden acceleration, braking and turns. All of these unexpected vehicle movements can be set as events in the Event module and can be displayed on the map.

Green Driving is not a module, but a set of functionalities on the map and in the Reports module.

 

Purposes of Green Driving

Green Driving functionality has the following aims:

  • reduction of fuel usage
  • reduction of maintenance costs
  • concern for goods or people in the vehicle
  • concern for the public image of the company whose logo or brand the vehicles bear
  • being “green” in general.
 

How Green Driving is displayed on the map

Any sudden acceleration, braking or cornering is displayed on the map with a dot in distinctive colour. When the user hovers the mouse over the dot, more information about the occurrence is shown:

In the example above, user should pay attention to the row “Green Driving” on the pop-up. The image on the left shows a cornering event. The image on the right shows sudden braking.

 

Units of measurement

Different units of measurement are used to measure different events.

The unit of measurement for acceleration and braking is km/h/s, or how much the speed changes in one second. As the value of the braking force in the picture on the right is given as 22 km/h/s, it means that the force used in braking is equal to the force required to bring a car travelling at a speed of 88 km/h to a complete stop in just 4 seconds.

The unit for aggressive turns is ‘degrees per second’, which in the example given means that in one second the direction of the car changed by 26 degrees, while at the same time maintaining a speed of 51 km/h. At such a speed, a 90-degree turn would take three and a half seconds.

 

What reports become available with Green Driving

There are two reports:

  • Green Driving daily report provides daily accounts of green driving events.

  • Green Driving period report provides an overview of all green driving events during a selected time period. Vehicles performing above average with are colored green and those performing below average, red.

greendriving-report2

In addition to the number of events (‘accelerations’, ‘brakings’, ‘turns’), the report also displays the ratio of events to distance travelled. There is a difference whether 10 green driving events happen within 10 kilometres (1 event per 1 km) or 100 kilometres (0.1 events per 1 km).

 

Green Driving for Trucks

This feature enables to to pick out the coincidences where truck is being abused by the driver, based on CAN data. See the examples below.

 

Setup

  • Go to Settings -> Green Driving for Trucks

  • Create rules, such as:

Example 1:

Name: High RPM with cold engine

Parameters: RPM > 2500 & Coolant < 70°

Example 2:

Name: Clutch pedal too long

Parameters: Clutch = On & Duration > 30s

Example 3:

Name: Brake too long on high speed

Parameters: Brake = On & Speed > 70 & Duration > 20s

Example 4:

Name: Neutral on too long

Parameters: RPM > 400 & RPM < 900 & Duration > 30s

It all comes together from following parameters:

  • RPM (setting RPM range can help detect neutral gear)
  • Coolant temperature in Celsius
  • Brake
  • Clutch
  • Speed
  • Duration
 

Results

  • Two reports: GDFT daily and summary report

GDFT-daily-report

GDFT-summary-report

  • KPIs: event count and events per 100 km

GDFT-kpi

 

Things to keep in mind

  • Data collection starts after saving each rule.
  • When you change the rule, past collected events will not be recalculated.
