Green Driving Solution

Project description

Growing world population and development of new technologies contribute to the growth in use of transport. Driving style is one of the factors directly influencing fuel consumption and vehicle life, e.g. aggressive acceleration, harsh braking, harsh cornering and over speeding. Inefficient driving produces more exhaust gas emissions, thus, increasing the negative environmental impact on our planet.

What you need for a solution?

• All Teltonika FM devices are compatible with this use case.
• The SIM card in order to receive data to Your server.
• Teltonika Configurator to set up FM device correctly for the solution.
• FOTA WEB to remotely send the configuration to the device.
• BTAPP / Driver application to monitor and score driver behavior. Real time events notifications about harsh acceleration, braking, cornering, over speeding, idling and RPM. Solution designed to improve driver behavior and productivity.

Installation

It is good to know that this functionality is supported by all Teltonika vehicle trackers.

In case of the driver alert function, please note that the device must have DOUT for this feature to work.

What is also important, there are two sources for Green Driving operation – GPS data and accelerometer. The desired one can be selected in Configurator. GPS data is pretty reliable and does not require any additional effort to make it work. On the other side, accelerometer data is more precise and ensures uninterrupted operation even when GPS signal is not available, for example, in tunnels or underground parking lots. However, in order to utilize accelerometer data correctly, the device has to perform autocalibration process, which is automatic, as the name implicates, but may take some time.

Configuration

2. Configuration of Green driving scenario:

Before configuring Green driving solution it is important to set up GPRS settings for a device.

2.1. GPRS settings

Parameter ID – Parameter name GPRS settings:

• 2001 – APN
• 2002 – APN username (if there are no APN username, empty field should be left)
• 2003 – APN password (if there are no APN password, empty field should be left)

Server settings:

• 2004 – Domain
• 2005 – Port
• 2006 – Data sending protocol (0 – TCP, 1 – UDP)

After successful GPRS/SERVER settings configuration, FMB920 device will synchronize time and update records to the configured server. Time intervals and default I/O elements can be changed by using Teltonika Configurator or SMS parameters. After familiarizing with devices first start guide and device's GPRS settings are set - configuration for Green driving can be done.

"  setparam 11800:1;11801:0;11806:1;11000:2;11007:1;11200:2"

This SMS will set up Your device to send Trip, Eco/Green driving and Excessive idling data to Your previously provided server.

Note: Before SMS text, two space symbols should be inserted if no SMS username or password was set in SMS / Call settings.

3. BTAPP Mobile application

After making configuration for Your device, it is time to download BTAPP. Keep in mind, app and device connection is established via Blue-tooth. Devices by default come with Blue-tooth enabled and visible. After pairing to device - You can change the trip type of Your trips by performing a long press on the icon and confirming the change.

When vehicle parameters exceed the values of Max Acceleration, Max Braking or Max Cornering parameters, the scenario is activated: a record is generated, and digital output status is changed to 1 when configured. You can configure all three parameters in m/s² units. The scenario is activated until the current Acceleration, Braking, or Cornering value decreases below the set parameter value.
Parameters used with Eco/Green Driving functionality are given in a table below.

Parameter name	Description
Scenario Settings	Enable/Disable Green driving functionality
Max Acceleration	Value which can be reached while accelerating without triggering harsh acceleration event.
Max Braking Acceleration	Value which can be reached while braking without triggering harsh braking event.
Max Cornering Acceleration	Value which can be reached while cornering without triggering harsh cornering event.
Source	Which source (GPS or accelerometer) data will be collected from.
Advanced Eco Driving	When this parameter is enabled device uses an advanced Eco Driving algorithm and sends different IO (maximum, average) elements instead of IO to server. More details about this option is decribed below.
Eco/Green Driving Duration	If enabled, additional record with Eco/Green Driving event duration (ms) will be saved and send to server. When GPS is selected as the data source duration accuracy will be in seconds.
Output Control	Which FMB1YX Digital Output will be used for accesory (buzzer, LED and etc.) activation/deactivation.
DOUT ON Duration	A value in miliseconds (ms), for how long DOUT should be active.
DOUT OFF Duration	A value in miliseconds (ms), for how long DOUT should be inactive.
