Fleet Management Glossary

Fleet technology, explained clearly

18 terms

ADAS
Advanced Driver Assistance Systems: technologies that warn or assist a driver, such as following-distance or lane-departure alerts. Available functions depend on the installed system.
API
Application Programming Interface: a defined way for software systems to exchange information. Permissions, field definitions and error handling are part of the contract.
CAN bus
Controller Area Network: the vehicle network through which electronic control units exchange messages. Available fleet data varies by vehicle and integration.
DMS
Driver Monitoring System: a system that detects selected in-cab behaviours or signs associated with driver attention. Detections require context and appropriate review.
DTC
Diagnostic Trouble Code: a fault code reported by a vehicle system. A code supports investigation; it is not a complete repair diagnosis.
EV
Electric vehicle. Fleet analysis typically considers duty cycle, battery state of charge, energy consumption and charging availability.
FNOL
First Notification of Loss: the initial report of an incident to the relevant claims process, supported by available facts and evidence.
Geofence
A virtual geographic boundary used to identify entry, exit or presence. Accuracy depends on position quality and configuration.
GNSS
Global Navigation Satellite System: the broader category of satellite positioning systems, including GPS.
Idling
Engine operation while a vehicle is stationary. Some idling supports operational equipment, so context matters when assessing avoidable fuel use.
MDVR
Mobile Digital Video Recorder: an in-vehicle recording unit that can capture multiple camera channels, with connectivity and storage depending on the model.
OEM data
Data supplied through a vehicle manufacturer’s systems. Coverage, permissions and signal definitions vary.
ROI
Return on investment: net benefit divided by investment over a stated period. Cost boundaries and assumptions must be consistent.
State of charge
An estimate of remaining battery charge, usually expressed as a percentage. It is distinct from battery health and charging status.
Tachograph
Equipment that records specified vehicle and driver activity. Remote download availability depends on compatible hardware, authorisation and configuration.
Telematics
The collection and communication of vehicle or asset data to support operational decisions.
TPMS
Tyre Pressure Monitoring System: sensors and related systems for reporting tyre pressure, and sometimes temperature.
Video telematics
The combination of vehicle data and camera recordings to provide context for safety, operations and incident review.
