Speed Limiting Solution FMC130+ETC

Introduction

The loss incurred globally by corporate fleet and insurance businesses due to accidents caused by over speeding is significant. This can often lead to the loss in productivity and multiple other evident collateral damage costs. We at Teltonika Telematics have developed a unique solution to help tackle over speeding in the fleet.

Solution description

Using the combination of Teltonika FM device with the Automotive relay and the Electronic throttle controller to achieve speed limiter feature.

What you need for a solution?

• FMC130 device
• Electronic Throttle Controller
• Automotive Relay
• The SIM card in order to get data to your server
• FOTA WEB to remotely send the configuration to the device.
• *Solenoid Valve

*Solenoid Valve is optional for one of the wiring schemes shown below

Installation

This solution can be implemented in 3 different ways based on the speed limiting scenario. It’s important to install the device and the relay in an hidden place inside dashboard.

Although devices have high gain antennas it’s important to mount devices with stickers on top and in metal-free space. The device should be firmly fixed to the surface or cables. Please make sure, that device is not fixed to heat emitting or moving parts.

To have a working solution it’s important to properly wire the devices. In the picture below it's shown how to correctly wire the device when implementing electronic throttle controller solution.

There are 3 ways of connecting the FM device which are displayed below:

A. Installation - Electronic Throttle Controller

B. Installation - Fuel Pump

C. Installation - Solenoid Valve

Wiring Scheme

Relay Wiring Scheme

Relay PIN	Relay cable color	Connection
30	Blue	+VDC (Common connection to NO & NC terminals)
85	Black	DOUT of FM Device
86	White	+VDC (Coil)
87	Yellow	Not Required to connect (Normally Open (NO))
87a	Red	Green Wire from ETC or Wire to Fuel Pump or Wire to Solenoid Valve

ETC Wiring Scheme

ETC cable color	Connection
Red	+VDC (+10...32)
Black	Ground
Green	PIN 87a (NC of Relay)
White	V-/0.40V from Accelerator pedal
Brown	V+/0.70V from Accelerator Pedal
Yellow	S+/0.70V from ECU
Grey	S-/0.40V from ECU

Note: Voltage may vary depending on vehicle model.

During installation please follow recommendations in order to avoid damaging device and vehicle:

• while the connecting the wires, please ensure the module is not plugged IN.
• Ensure the car ECU falls asleep, measure voltage on the chosen wire if it is still available. It usually takes 5 to 30 minutes period for the ECU to completely shutdown depending on the model of the vehicle.
• When the module is connected, be sure to measure the voltage again if it did not decrease.
• The ground wire is connected to the vehicle frame or metal parts that are fixed to the frame.
  

Configuration

2. Configuration - Speed limiting:

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, FM 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.

Sleep settings:

• 102 – Sleep settings(0 – Disable, 1 – Gps sleep, 2 – Deep sleep, 3 – Online Deep sleep, 4 – Ultra sleep)

Note: This scenario will not work with Deep Sleep and Ultra Sleep modes, since they disable the device's GSM module to save power.

To setup the speed limiting feature in the configurator we should navigate to Features → Over Speeding where we would set a priority for the event, speed source and DOUT 1 for the relay to work properly.

Over speeding settings

• 11100 – Scenario settings(0 – Disable, 1 – Low Priority, 2 – High Priority, 3 – Panic Priority)
• 11104 - Max Speed (Default value - 90 km/h)
• 13217 - Speed Source (0 - GNSS (Default), 1 - OBD, 2 - AIN1)
• 13223 - Over speeding Hysteresis (Default value - 8%), value that determines what would be the threshold speed level that would activate the speed limiting feature
• 11103 - Output Control (0 - None (Default), 1 - DOUT1), DOUT1 needs to be enabled to use the speed limiting feature

Note: The speed will be limited within +10 km/h from the configured speed if the speed source is set to GNSS and for more accuracy CAN adapters can be implemented.

Quickstart: From default configuration to Speed Limiting solution in one SMS:

"  setparam 2001:APN;2002:APN_user;2003:APN_password;2004:Domain;2005:Port;2006:0;102:3;11100:2;11104:90;13217:0;13223:8;11103:1;11101:5000;11102:0"

This SMS will set up your device to report the Speed Limiting scenario to the server.

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

3. Configuration - Speed Limiting based on Geo-Fence

Manual Geofence settings

• 20100 – Scenario settings(0 – Disable, 1 – Low Priority, 2 – High Priority, 3 – Panic Priority)
• 20101 - Generate Event(0 - Disable, 1 - Low Priority, 2 - High Priority, 3 - Panic Priority)
• 20104 - Shape Type(0 - Circle,1 - Rectangle)
• 20105 - Radius in Metres
• 20106 - X1 Coordinate
• 20107 - Y1 Coordinate
• 20108 - X2 Coordinate
• 20109 - Y2 Coordinate
• 20110 - Overspeeding(0 - Disable, 1- Enable) should be enabled for speed limiting functionality.
• 2005 - Max allowed speed km/h.

Note: The speed will be limited within +10 km/h from the configured speed if the speed source is set to GNSS and for more accuracy CAN adapters can be implemented.

Conclusion

Speed limiting is achieved when max speed is exceeded. Relay is activated on DOUT1 which will disable the acceleration pedal, turn off the fuel pump or close the solenoid valve.

Note: The speed will be limited within +10 km/h from the configured value when the speed source is set to GNSS. To achieve the accurate speed limiting CAN adapters can be implemented.
