To work with the Eco driving tab, you should have the following access rights:
- View detailed object properties. To view the tab.
- Edit trip detector. To edit the tab.
On this tab, you can select the method which should be used to calculate acceleration and add criteria which allow you to assess the quality of driving and detect violations. This is required in order to improve the safety of driving, maintain the quality of transported goods, and reduce fuel costs.
The tab contains a list of all the added criteria and their parameters.
After adding the criteria and specifying all the required parameters, you can execute a report with detailed information about all the violations for the selected interval.
Calculating acceleration
Acceleration is the difference in the unit speed divided by the difference in time. The movement direction of the unit allows determining the acceleration type: speeding, turn, reckless drivings, etc.
When calculating acceleration, the following data is used:
- unit location;
- initial and final speed values;
- travel time between two points;
- unit movement direction;
- values of special parameters sent by the device.
Three methods for calculating acceleration are available.
| Method | Description |
|---|---|
| GPS and Eco driving parameters | The acceleration is calculated both according to the data on the unit location, speed, movement direction and time and on the basis of special parameters sent by the device. Then the system selects a higher value. |
| Eco driving parameters | The acceleration is calculated by the device on the basis of special parameters which contain the maximum speed values for the period between two messages. These parameters can be transmitted only by some devices. The calculation method based on the eco driving parameters is more accurate because the calculation doesn't depend on the frequency of sending data. |
| GPS | The acceleration is calculated according to the data on the unit location, speed, movement direction and time. |
By default, the acceleration is calculated according to the GPS and Eco driving parameters method.
You can select the required calculation method depending on the type of equipment used.
The selected method is applied to all the configured criteria.
Adding criteria
Depending on the vehicle type, you can add a list of criteria with the already configured parameters. To do this, select the required template from the three available options (Automobile, Truck, Bus) and click on the Add button.
The criteria of the selected template are automatically added to the list.
To add a new criterion on your own, click on the Add a new criterion button (
), specify its basic parameters, and, if necessary, the advanced ones.
To discard the changes, click Clear. To cancel adding the criterion, click Cancel. To save it, click Save.
Basic parameters
To configure the criterion, specify its basic parameters. The required fields are marked with an asterisk (*).
| Parameter | Description |
|---|---|
| Criterion* | Select one of the available criteria which should be used when assessing the quality of driving:
Each violation is fined by adding the number of penalty points specified in the Penalty field. |
| Name* | Specify the name of the criterion. |
| Sensor* | The parameter is available only when the Custom criterion is selected. In the drop-down list, select one of the created sensors the values of which should be used when detecting violations. If a digital sensor is selected, the Violations from device option is available. If you activate this option, the violation duration coincides with the interval of the sensor operation. |
| Min./Max. value | Specify the minimum and maximum values of the selected criterion which should be considered a violation. If the received value of the criterion falls in the specified interval, a violation is detected. The interval doesn't include the value that you specified as the maximum one. For the Speeding criterion, the values are specified in km/h; for the Acceleration, Braking, Turn, Reckless driving criteria, in g. For the Custom criterion, the values of the selected sensor are specified. |
Penalty* | Specify the number of penalty points which should be added for each violation according to the selected criterion. |
The intervals of all criteria, except for the Custom one, can be combined. For example, if one violation is followed by another one based on the same criterion within 10 seconds, these violations are combined.
Advanced parameters
If necessary, specify the advanced parameters of the criterion.
| Parameter | Description |
|---|---|
| Validator | In the drop-down list, select one of the created sensors you want to use as a validator for confirming or rejecting the received values of the selected criterion. If at least one positive value of the validator is received, a violation is detected. After selecting the validator, the Multiplier option is available. If you activate it, the number of penalty points for the violation is multiplied by the value of the selected sensor. For example, if you want to monitor speeding when transporting goods, you can create a weight sensor, select it as a validator, and activate the Multiplier option. If the vehicle is not loaded with goods, the sensor value is zero; if loaded, the value is greater than zero. In this case, if the speed is exceeded when transporting goods, the number of specified penalty points is multiplied by the validator value. |
| Averaging | Select one of the available options to calculate averaging:
If the averaging is disabled (the None option), all the penalty points of the trip are summed up. Averaging by mileage and by time doesn't apply to trips the duration of which is less than a minute. |
| Min./Max. duration, sec | Specify the duration range of the criterion in which violations should be detected. If the criterion duration exceeds the specified minimum value, a violation is detected. If the criterion duration exceeds the specified maximum value, the number of penalty points is multiplied by the number of maximum values of the criterion for the violation interval. |
| Min./Max. speed, km/h | Specify the speed range at which violations should be detected. The system determines the maximum speed at the violation interval and compares it with the values specified in these fields. If the speed falls in the specified range, a violation is detected. For example, you can specify only the minimum speed here. This allows not taking into account violations (speedings, accelerations, brakings, etc.) when moving at a speed the value of which is less than the specified one. |
Actions with criteria
To perform actions with criteria, use the icons at the end of each line.
| Icon | Description |
|---|---|
| Open the criterion properties. |
| Create a new criterion with the same properties. A click on the icon opens the window for creating a new criterion where you can make changes and save them. |
| Delete the criterion. |
Reports
If all the parameters of the tab are specified correctly, you can execute a report with the Eco driving table, or add the Penalties and Rank columns to the following tables:
- Geofences;
- Counter sensors;
- Engine hours;
- Unfinished trips;
- Trips;
- Trips between geofences;
- Summary;
- Digital sensors;
- Statistics.
