Abstract: In general, techniques are described by which to provide streaming via a hardware abstraction layer. A cartridge comprising a memory, and a processor may be configured to perform the techniques. The processor may execute a second version of an operating system, and receive a stream, via an interface and to a first version of the operating system executing on a processor of a head unit of a vehicle, information relating to an application executing in the application layer exposed by the first version of the operating system. The information relating to the application may include a first function call that conforms with the first version of the operating system, where the cartridge is communicatively coupled to the head unit. The interface may transform the first function call to a second function call that conforms with the second version of the operating system.

Abstract: In general, techniques are described for extensible mappings for vehicle system busses. A device configured to interact with a vehicle may perform the techniques. The device may comprise a memory that stores an extensible mapping between a local control message and a standard control message. The device may also include a processor configured to execute an operating system to control a system of the vehicle. The operating system may generate the standard control message, where the standard control message includes a first representation of a command set. The processor may translate, based on the extensible mapping, the standard control message to obtain the local control message, the local control message including a second representation of the command set. The processor may transmit, via a control bus coupled to the processor and the system, the local control message to initiate an operational state change of the system.
