Yaw
Full qualified VSS Path: Vehicle.Occupant.Row1.Middle.HeadPosition.Yaw
Description: Head yaw angle, measured from the vehicle sprung mass X-axis as defined by ISO 23150:2023 to the head X-axis, around the vehicle Z-axis (right-hand rule). 0 = Head in normal position. Positive values = Head turned left. Negative values = Head turned right.

Eclipse Leda: Usage Example

In Eclipse Kuksa.VAL Databroker CLI:

$ databroker-cli
sdv.databroker.v1 > connect
[connect] OK
sdv.databroker.v1 > get Vehicle.Occupant.Row1.Middle.HeadPosition.Yaw
[get]  OK
Vehicle.Occupant.Row1.Middle.HeadPosition.Yaw: ( NotAvailable )
sdv.databroker.v1 > set Vehicle.Occupant.Row1.Middle.HeadPosition.Yaw 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
uint32 unsigned 32-bit integer 0 4294967295
int32 signed 32-bit integer -2147483648 2147483647
uint64 unsigned 64-bit integer 0 2^64 - 1
int64 signed 64-bit integer -2^63 2^63 - 1
boolean boolean value 0/false 1/true
float floating point number -3.4e -38 3.4e 38
double double precision floating point number -1.7e -300 1.7e 300
string character string n/a n/a

Min, max and default values defined in a Vehicle Signal Specification must be in the supported range of the data type.
