The customer’s challenge

Tribus develops a unique modular city bus. The electrical and software integration of mostly existing automotive components requires a carefully designed E/E architecture. This development process from requirements to acceptance needs to be strictly managed.

Sioux’s contribution

Sioux determined the functional requirements and supported the vehicle component selection. Sioux used its partnership with Continental and selected the KIBES multiplex system, the driver workplace with MultiViu Professional 12” display and the Sioux LIN to CAN Gateway. We implemented and systematically tested all software before integrating the vehicle components. In addition, Sioux configured all gateways, vehicle components and created the graphical HMI design and software for the dashboard.


A state of the art and fully functioning electric city bus, with a modern, clean and ergonomic HMI that matches the high demanding driver, passenger and fleet operators standards.
