Vehicle Signals

There are two types of query fields that you can use to retrieve vehicle signals from the Telemetry API, depending on if you’re looking for the latest signal data, or if you need to look up historical signal data from the past:

• The signals query allows you to retrieve signal data from a vehicle for a given time period. It is commonly used to perform look backs with a set interval within a time period for a vehicle.

• The signalsLatest query allows you to retrieve the most recent signal data from a vehicle. It returns the latest signals received from the respective data sources.

signals

The signals resource is an aggregation of detailed signal fields, used to retrieve vehicle signal data between a specified time period in the past.

Arguments

Filter Field	Type
tokenId	Int!
from	Time!
to	Time!
interval	String!
filter	SignalFilter

When using signals, be sure to also include the relevant aggregation type.

{
  signals(
    tokenId: 12345
    from: "2024-05-07T09:21:19Z"
    to: "2024-05-10T09:21:19Z"
    interval: "24h"
  ) {
    timestamp
    speed(agg: MAX)
  }
}

signalsLatest

The signalsLatest resource is a SignalCollection that returns data for any signal that was most recently seen matching the filter.

Arguments

Filter Field	Type
tokenId	Int!
filter	SignalFilter

When using signalsLatest, be sure to include a value and optionally a timestamp

{
  signalsLatest(tokenId: 12345) {
    powertrainTransmissionTravelledDistance {
      value
    }
    powertrainFuelSystemRelativeLevel {
      value
      timestamp
    }
  }
}

Fields By Category

Key:

• Signal: The field name that can be queried for signals or signalsLatest.

• Common Name: A simplified, consumer-friendly naming convention for the signal.

• Aggregation (Agg.) Type: The Aggregation Type as specified for the signals resource.
• Units: The unit returned for the specific signal quieried, if relevant.

• Description: A longer description for the specific signal.
