ADASIS v2 HR Blockset

ADASIS v2 system architecture

The ADASIS v2 Interface Standard
To support the development of predictive, map-based driver assistance systems, the ADASIS Forum ( www.ertico.com/adasisforum ) produced a standardized interface for access to electronic horizon data. This is called the ADASIS v2 standard. The members of the ADASIS Forum include car makers, ECU suppliers, and the vendors of navigation systems and digital road maps. dSPACE is also a member, true to our aim of providing a portfolio of tools for developing and testing driver assistance applications.

Linking the dSPACE MicroAutoBox to an electronic horizon provider via the ADASIS v2 protocol

The automotive industry is making increasing use of the ADASIS v2 standard. In vehicles, a unit called the ADAS v2 provider (typically a navigation system or a special ECU without a graphical user interface) makes the electronic horizon available to other ECUs via the CAN vehicle bus. These ECUs interpret the standardized transmission protocol and use a software component called an ADASIS v2 reconstructor to evaluate the road attributes that are relevant to a particular application.

ADASIS v2 System Architecture
To help users develop driver assistance systems in fast iteration cycles and directly experience the effects in a vehicle, dSPACE offers the ADASIS v2 HR Blockset, a flexibly adaptable ADASIS v2 horizon reconstructor blockset for the rapid prototyping systems MicroAutoBox and AutoBox. This blockset provides access from within a Simulink^® model to electronic horizon data that is transmitted via the ADASIS v2 protocol. Only a few mouse clicks are needed to select the predictive road data, connect it to the actual driver assistance function in the model, and generate the real-time code simply by clicking a button and load it to the development system. This means that function developers can can give their full attention to implementing the actual application functions. They do not face the time-consuming challenge of implementing the ADASIS v2 protocol themselves.
In addition to the CAN bus, the dSPACE ADASIS v2 HR Blockset also supports Ethernet as a transmission medium.
