What does a vehicle require so it has the capability to drive completely autonomously? And what should the technological basis be, to allow for the step-by-step development of HARRI to achieve the capacity for driverless mobility? In 2017, we, the Bertrandt team of experts began our journey with all of these considerations in mind.
Cloud-based platform
A high-efficiency vehicle networking architecture, the integration of sensor technology and sufficient processing power constitute the decisive aspects required for autonomous driving. With our specifically developed domain and systems architecture, our IT experts have created the future-oriented, high-performance basis to achieve this. Together, the back-end and vehicle control all vehicle functions, whereby the vehicle itself is also functional without the cloud.
Moreover, all vehicle data are recorded, processed and analyzed in the cloud. And that includes gradually providing HARRI with the capability to connect and to find his way around, to take control and to learn (AI).
Design decisions and vehicle development
It was important early on for autonomous driving to deal intensively with the interaction of human and machine (HMI) or that of vehicle and environment—and to derive design decisions from these considerations, e.g. for lights, traffic signals and other communications media. It was abundantly clear that a vehicle that drives entirely autonomously needs neither mirrors nor a steering wheel. But what should the vehicle actually look like? Initial design ideas came from trainees as part of an internal contest. Our design team picked up on some of these up and further advanced their development. Ultimately, the mechanical aspects were developed based on simulations and the vehicle was assembled in the model making unit.
On the road to driverless mobility in SAE levels 4 and 5
In its current state, HARRI is not yet roadworthy. However, in terms of technology, he is equipped with everything he needs for gradual further development from assisted to automated or autonomous driving.
Integrated solutions:
- In-house domain architecture
- In-house system architecture
- Electrical system development
- Drive-by-wire system
