Methods for the Development of Collaborative Embedded Systems in Automated Vehicles © FEV Europe GmbH
In future automated vehicles, collaborative embedded systems will work in system groups within a dynamic context that poses a particular challenge for design and test concepts. The complex development process must be supported by a heterogeneous tool environment. In the CrESt research project, RWTH Aachen University and FEV Europe are pursuing the goal of establishing interoperability between different tools. In this paper, four development types and tool methods are presented which address these challenges.

INTRODUCTION
Driving assistance systems already have a long history. Since the 1950s, for example, cruise control to keep a vehicle traveling at a constant speed has played an increasingly important role. With Adaptive Cruise Control (ACC), today’s vehicles can follow others at a predefined distance by controlling the longitudinal dynamics with the aid of sensors. Collaborative Adaptive Cruise Control (CACC) is an advancement of this technology, enabling prospective vehicles to adapt their speed to others in front with direct Vehicle-to-Vehicle (V2V) communication. CACC systems can react more directly to speed fluctuations of the vehicle in front,

even if it is outside the line of sight, due to the absence of technically induced dead times. These new types of systems do not exclusively use sensor data for operation, but are increasingly equipped with open interfaces and include communication and collaboration beyond the vehicle (Vehicle-to-everything, V2X). They form so-called Collaborative Em bedded Systems (CES). When these systems collaborate, they can communicate to achieve strategic goals at a higher l evel in a so-called Collaborative System Group (CSG). The development of CES is subject to characteristic challenges, such as operating in an open context that changes dynamically in an unpredictable

manner at design time. The systems must work together and be able to change their behavior at runtime. High security risks exceed the level of conventional systems whose design and test concepts here are insufficient. Therefore, new methods for the development of collaborative embedded systems have to be found. In this paper four development and tool methods are presented that address these challenges.
