| Full qualified VSS Path: | Vehicle.AverageSpeed |
| Description: | Average speed for the current trip. |
| Comment: | A new trip is considered to start when engine gets enabled (e.g. LowVoltageSystemState in ON or START mode). A trip is considered to end when engine is no longer enabled. The signal may however keep the value of the last trip until a new trip is started. Calculation of average speed may exclude periods when the vehicle for example is not moving or transmission is in neutral. |

About VSS
The Vehicle Signal Specification (VSS) is an initiative by COVESA to define a syntax and a catalog for vehicle signals. The source code and releases can be found in the VSS github repository.
