eSOL Announces Development of its eBRAD AI framework

The use of psychological domain knowledge allows design reviews and enableAI generation from small datasets
Tokyo, Japan. September 28, 2018 -eSOL, a leading developer of real-time embedded software solutions, today announced
that it is developing eBRAD* (the eSOL BehavioR ADaptation engine), an AI framework that can control autonomous driving
and other kinds of automation in the form of an AI personalized to the characteristics and behaviors of human drivers.
The announcement will be made today by Masaki Gondo, CTO and General Manager, Engineering Division, at the eSOL
Technology Forum 2018, a private conference hosted by eSOL.

eBRAD is a framework that incorporates knowledge of autonomous driving, in the form of an AI personalized to the
characteristics and behaviors of human drivers. The three steps of autonomous driving are recognition, judgment and control.
This decision-making algorithm determines the driving actions that in turn determine vehicle behavior. While the majority of
autonomous driving systems currently attempt to behave homogeneously like an ideal averaged driver, prior researches of
driving behavior have found significant variations in the way people drive: there are large differences between what each
person considers to be “normal driving”, depending on several parameters like location, climate conditions, car model, or
driver personality. eBRAD provides a way to generate decision-making models that are personalized based on how people
actually drive. This helps to deliver autonomous driving functions that feel more natural and human-like. The algorithms also
help make the manual driving Advanced Driver-Assistance Systems (ADAS) safer and less intrusive, by predicting driver
actions and adapting to the driving characteristics of a particular individual

Another aspect of the design is the ability to conduct design reviews, a vital part of software quality assurance. This property
is retained because it is the system developer who designs the core network structure of the AI, using existing domain
knowledge about driver behavior psychology. This also means that analyses can be conducted when problems arise.
Additionally, because the core structure is provided, the volume of data required in the machine learning phase is much lower
than for deep learning, to a level that the vital data on individual drivers needed for personalization can be obtained, and AI
training conducted, in a realistic timeframe.

The eBRAD SDK provides a comprehensive toolset to use the AI framework together with a runtime engine, to incorporate
the algorithm into target systems. Development of the runtime draws on the OS technology and expertise in advanced
parallelization using multi/many-core processors that eSOL has built up over many years, combining a high level of
performance and efficiency with the prospect of support for functional safety certification.

Beyond automotive applications like autonomous driving (AD) systems and ADAS, the technology also has potential uses in
other systems where human actions can be automated. eSOL intends to work with partners to also offer support for
applications outside AD and ADAS.

By making the eBRAD SDK commercially available, eSOL will support the development of both the next generation of
autonomous driving systems and of automated and semi-automated systems in other industries, including healthcare.

eSOL CTO and General Manager, Engineering Division Masaki Gondo commented that “In this time of innovation when
advances in automation are taking place in automotive as well as many other sectors, I believe that eBRAD offers an extremely
effective way to address the growing challenge of making AI less homogeneous and more personalized. It also offers an
approach that takes full advantage of the domain knowledge that represents the greatest core asset of the system manufacturers
who have been our customers for many years, without relying on large amounts of data and computational resources. Rather
than a world in which data is everything, the aim is to provide system manufacturers with a new tool that utilizes data, but on
a base of knowledge and expertise.”
