Navya ARMA | Dossier modular software interface and the CAN hardware interface used in the controllers allow different V2V and V2X technologies to be used in other regions of the world such as the US and Asia, which operate at different radio frequencies. Controllers ARMA uses two electronic control units (ECUs) developed by Eve System, using a standard CAN bus to communicate with the ARMA’s central processing board. The ECUs handle the powertrain control, as well as the hydraulic and electromagnetic braking systems, which provide engine braking at a maximum deceleration of 3 m/s 2 , while the brakes provide 5 m/s 2 , bringing the vehicle to a stop in less than 0.5 s. The central controller consists of two fanless high-end industrial PCs from Taiwanese supplier Perfectron. The PCs are specified for the temperature range of -40 to 70°C and use Intel’s high-end processor, the Core i7. One PC handles the sensor software and the fusion algorithms, while the other handles the decision process and the comms with the supervision centre via a V2X link. This second PC also controls the outside and inside screens for human-machine interactions. Future development includes moving to the Linux operating system with extensions for real-time operation, called Posix, and then to a real-time operating system. The 33 kWh battery pack is the heart of the ARMA platform
