Torque
Full qualified VSS Path: Vehicle.Powertrain.CombustionEngine.Torque
Description: Current engine torque. Shall be reported as 0 during engine breaking.
Comment: During engine breaking the engine delivers a negative torque to the transmission. This negative torque shall be ignored, instead 0 shall be reported.

Eclipse Leda: Usage Example

In Eclipse Kuksa.VAL Databroker CLI:

$ databroker-cli
sdv.databroker.v1 > connect
[connect] OK
sdv.databroker.v1 > get Vehicle.Powertrain.CombustionEngine.Torque
[get]  OK
Vehicle.Powertrain.CombustionEngine.Torque: ( NotAvailable )
sdv.databroker.v1 > set Vehicle.Powertrain.CombustionEngine.Torque 0
[set]  OK

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.

Supported datatypes

The following is a list of VSS supported built-in datatypes:

Name Type Min Max
uint8 unsigned 8-bit integer 0 255
int8 signed 8-bit integer -128 127
uint16 unsigned 16-bit integer 0 65535
int16 signed 16-bit integer -32768 32767
