MicroAutoBox Embedded SPU

Compact and robust in-vehicle prototyping unit for multisensor applications

The MicroAutoBox Embedded SPU (Sensor Processing Unit) is a compact and robust prototyping unit with high processing power and an intuitive software environment for the development of advanced driver assistance systems and highly automated driving functions. It can be used as a stand-alone system or as an extension to MicroAutoBox II.

MicroAutoBox Embedded SPU is still under development. The information provided on this page is preliminary and subject to change without notice.

Tackling the Challenges of Multisensor Applications

Multisensor applications play an essential role in many areas, such as advanced driver assistance systems (ADAS), automated driving, self-driving vehicles, and robotics. The development of these kinds of applications requires a dedicated hardware and software environment that can process and merge data from various sensors, such as cameras, lidars, radars and GNSS receivers, calculate motion control algorithms, and connect to actuators or HMIs. In addition, sensor and vehicle network data has to be recorded and played back synchronously for testing. To prototype associated algorithms in the vehicle and to process the enormous volume of data, a compact and robust prototyping unit with high processing power and an intuitive software development environment is required. MicroAutoBox Embedded SPU (Sensor Processing Unit) in combination with RTMaps (Real-Time Multisensor applications) is precisely tailored to this use case.

Unique Combination for ADAS and Beyond

The Embedded SPU is a unique combination of high processing power, interfaces to automotive vehicle networks, environment sensors, GNSS positioning, wireless communication, and an extremely compact and robust design for in-vehicle use. Using RTMaps, you can directly access and configure all interfaces of the Embedded SPU by means of ready-to-use block diagrams and design your algorithms for sensor data processing, sensor fusion, etc. in short iteration cycles and in a graphical environment. Each sensor data sample is captured along with its time stamp at its own genuine pace. This ensures that all data is time-correlated. It can even be recorded to an external mass data storage unit (MicroAutoBox Embedded DSU) with high data throughput and then be played back later on. In addition, it is possible to process algorithms on multiple distributed Embedded SPUs while preserving time coherency and synchronization of heterogeneous data streams.
