Vehicle Signal Interface

The Vehicle Signal Interface formerly known as Vehicle Model interface type creates an interface to a signal interface described by the VSS spec. This interface will generate a source code package equivalent to the contents of your VSS JSON automatically upon devContainer creation.

If a Vehicle App requires a vehicle-signal-interface, it will act as a consumer of datapoints already available in the system. If, on the other hand, a Vehicle App provides a vehicle-signal-interface, it will act as a provider (formerly feeder in KUKSA terms) of the declared datapoints.

Furthermore, in the source code generated by this functional interface, a connection to Kuksa Databroker will be established via the configured Velocitas middleware. It uses the broker.proto if provided by the Kuksa Databroker to connect via gRPC. A seperate declaration of a grpc-interface for the databroker is NOT required.
