The NCAP test catalogue for Automated Emergency Brake (AEB) systems include different scenarios. Handling these scenarios requires the usage of data fusion for the environment perception of the vehicle. Data fusion increases the data quality of sensors and combines the strengths of multiple sensors. Due to the increased data quality, AEB systems are more precise, reliable and safe.

Benefits of data fusion for AEB
Less false alarms to prevent unintended braking
- Data fusion allows to separate false-positive measurements from real objects.
- For an AEB system this is an important feature in order to prevent unintended braking which might lead to a dangerous rear-end collision.
Faster confirmation time
- In order to get enough confidence in an object hypothesis, a best practice is to confirm a single object over time by multiple successfully measurement associations.
- For an AEB system, a higher update rate leads to smaller safety margins and thus an improved end-user experience.
Improved surveillance area for next generation AEB
- Future evolutions of advanced driver assistance systems such as a city AEB for intersections and pedestrians need to observe more complex areas around the host vehicle.
- This can be achieved with the combination of heterogeneous sensor technologies.
- Data fusion is a methodology in order to address the challenges of different sensor input data representations and the object hand over task at the edges of the individual sensor field of views.
Suitable algorithms for series production
- Safety critical software algorithms for automotive series products such as an AEB system have to be developed according to safety standards such as ISO26262 for functional safety aspects.

BASELABS development support for AEB systems
We support our customers with tools and engineering services in the implementation of both data fusion prototypes and series systems. We can also offer complete driving functions with a partner company.
Tool support - prototyping
BASELABS Create provides relevant functionality for the implementation of the environmental model of an AEB system.
For automated vehicles that operate in urban areas and intersections, relevant objects may be those which cross the path of the vehicle. Detecting cross traffic participants properly is a challenge for environment perception systems, because e.g. front facing radar sensors cannot distinguish between a stationary object and a transversely driving vehicle within a single measurement cycle. Data fusion and tracking algorithms can overcome this limitation, This requires additional resources and enhanced modelling capabilities. BASELABS Create includes several sensor models for e.g. the MobilEye smart cameras that support the configuration and handling of cross traffic participants, e.g. to implement automated driving functions that fulfil Euro NCAP 2018 requirements.
The NCAP scenario catalogue also includes scenarios that require the proper recognition and tracking of vehicles in adjacent lanes. Sensors like radars typically perceive multiple reflections of close-by vehicles which is often denoted as extended object tracking. To reliably track these vehicles, data fusion systems need to be aware of this situation. BASELABS Create supports the configuration and handling of extended objects for radar sensors with built-in models, other sensors can be added by user defined models.
A third aspect which arises from the NCAP scenario catalogue is the detection of stationary vehicles. The track proposer of BASELABS Create is capable of initiating track hypothesises from such objects.

Tool support – series implementation
BASELABS Create Embedded (Release in Q4 2018) provides the same relevant features as our prototyping tool BASELABS Create (see above). In addition to the development capability, BASELABS Create Embedded yields functional safety approved C-source code for the usage in series production vehicles.
