Driver assistance features have been introduced to the market focusing on basic, independent functional scenarios. The trend is showing that these kinds of products are facing more and more complex scenarios and we are transitioning from single independent functions to a strongly networked system. Some of the drivers for future autonomous vehicles are 360° monitoring by active safety technology and V2X (vehicle to vehicle or vehicle to infrastructure) communication. In the past vehicles were strictly operated by the driver. Advanced driver assistance products added so called feedback features like lane departure warning, forward collision warning, and blind spot monitoring. First steps towards semi-autonomous driving started with the development of active support functions like adaptive cruise control or lane keeping support. Collision mitigation with various authority levels is the next milestone towards automation followed by other, even more advanced, features.

Connected vehicles provide suppliers and OEMs new opportunities to improve their customer experience and offer new services. Yet, in this new era of Internet of Things (IoT), OEMs and suppliers are expected to expand their engineering efforts beyond the vehicle itself. We present a new Rapid Application Development (RAD) service offered by IBM, called IBM Internet of Things Workbench. This is a visual tool, offered as an IBM Bluemix service that allows engineers to design and simulate the overall architecture and interactions between the various IoT entities such as devices, cloud applications and services, mobile clients and asset management systems. IoT Workbench abstracts the messaging details and generates code skeletons for the cloud applications as well as for simulating devices. It also provides the device simulation to allow for the application testing before the actual devices are available and the requirements for the various devices are validated.
