This Glossary collects, organizes and explains frequently used phrases, terms and questions related to fleet management and automotive technology:

  • What standards are used in fleet management?
  • What makes fuel consumption monitoring?
  • What is CAN bus?
  • What other in-vehicle communication protocols can be found there?
  • How does Fleet Management System work?
  • What is ECO-driving?
  • What is a tachograph unit and what are driving time rules?
  • How does trailer braking system work and what information can be acquired?

FMS standard is the result of an agreement between the six major European truck manufacturers to standardize the specific in-vehicle communication systems of the different types of vehicles

Fuel consumption monitoring is one of the most important functions of a fleet management system. Reducing the operational costs can easily be achieved by reducing the vehicle’s fuel consumption

CAN stands for Controller Area Network, meaning a computer network formulated by the vehicle’s electronic control units (ECU). CAN was primarily developed for automotive applications but later it appeared also in industrial, military, aerospace and nautical applications.

There are some in-vehicle communication protocols that are CAN based. These are mainly historic protocols, that were started and developed before the appearance of CAN protocol

Fleet Management is a basic requirement in modern vehicle fleets to provide cost efficient operation. These systems are complex with many electronic components installed in vehicles (FMS gateway, AVL, Board computer, etc.) and in the back office

ECO-driving is a driving attitude focusing on energy efficient using of vehicles. While transportation takes a significant share of the global carbon footprint of the world, ECO-driving helps to reduce fuel consumption thereby reduce fuel costs and CO2 emission

All commercial vehicles must be equipped with a tachograph unit. In the EU law there is a regulation about driving hours and rest time to avoid the crashes caused by driver fatigue. In this section you can read about the operation of tachograph units, the difference between analogue and digital types, tachograph card, driver’s identification types and driving times.

Almost every running heavy duty vehicle with gross vehicle weight over 7.5t has a trailer connected. For fleet managers it is important to know trailer specific information like gross vehicle weight, axle weight, brake status, tire pressure, ABS activation, roll-prevention activation, door statuses and EBS braking related information.
