Abstract
The bus-architecture of commercial vehicles and passenger cars differ significantly. Here the cruise control is integrated in the combustion engine's control unit. Due to different possibilities in commercial vehicles, e.g. torque measurement at the ancillary drive (PTO), engineers of Magna Powertrain/Engineering Center Steyr integrate the vehicle governor, the speed controller or the torque controller in an own control unit. This Hybrid Control Unit (HCU) includes the existing cruise control as well as the new additionally necessary controller structure for the hybrid mode. Therefore required E / E architecture as well as more efficient energy management are described in this article.
