event.absactivation

The event.absactivation event reports an ABS (Anti‑lock Braking System) activation occurrence detected on the asset. This event provides positional, motion, and load‑related contextual information to support safety analysis, diagnostics, and incident reconstruction.

Field level Description

Fields

Type

Description

eventSubscriptionId

String (UUID)

A unique identifier representing the subscription through which this event was delivered. It ensures traceability between the event and the organization's registered RMS subscription.

eventType

String

Defines the category of the event. event.absactivation indicates that the ABS system was triggered during a braking event.

eventId

String (UUID)

A globally unique identifier assigned to this specific event instance. Useful for event deduplication, tracking, and audit logging.

assetId

String (UUID)

Identifies the physical asset (e.g., vehicle, trailer, equipment) associated with this event. Used to correlate telemetry with a specific asset in fleet management systems.

unitId

String

A unique identifier of the telematics device generating the event. It often includes a namespace (e.g., traxee:) followed by the device’s serial or IMEI-like identifier.

eventData

Object

The eventData section contains detailed telemetry and contextual information about the ABS activation event.

registeredOn

DateTime (ISO 8601 timestamp, UTC)

Timestamp indicating when the ABS activation was detected and recorded. Expressed in UTC to maintain consistent cross‑system interpretation.

axleLoad

Number (kilograms)

Represents the measured load on the axles at the moment of ABS activation. Useful for understanding braking dynamics under varying loading conditions.

heading

Integer (degrees 0–359)

Indicates the direction of travel at the time of the event. 0° = true north, increasing clockwise.

mileage

Number (kilometers)

Total cumulative distance traveled by the asset up to the ABS activation point. Supports maintenance planning and event reconstruction.

latitude

Number (decimal degrees)

The geographic latitude where the ABS activation was recorded (WGS‑84 format).

longitude

Number (decimal degrees)

The geographic longitude corresponding to the event location (WGS‑84 format).

speed

Number (km/h)

Instantaneous speed of the asset at the moment the ABS system activated. Provides valuable braking context and supports safety event analysis.
